Patients with maxillectomy face problems with speech, swallowing, chewing and appearance. These defects are prosthetically rehabilitated with obturators that prevent oronasal communication, restoring function and social reintegration. An obturator must be light-weight, tight, easy to make and low cost. This article describes a simplified technique for fabrication of an acrylic hollow bulb obturator in two pieces using single flask. The prosthesis is made entirely of heat cure acrylic resin. The two parts of the obturator are sealed with the self-curing resin.

This paper presents the results from the characterization of pneumatic touch sensors (sensing bulbs) designed to be integrated into myoelectric prostheses and body-powered prostheses. The sensing bulbs, made of silicone, were characterized individually (single sensing bulb) and as a set of five sensors integrated into a silicone glove. We looked into the sensing bulb response when applying pressure at different angles, and also studied characteristics such as repeatability, hysteresis, and frequency response. The results showed that the sensing bulbs have the advantage of responding consistently to pressure coming from different angles. Additionally, the output (pneumatic pressure) is dependent on the size of interacting object applied to the sensing bulb. This means that the sensing bulb will give higher sensation when picking up sharper objects than blunt objects. Furthermore, the sensing bulb has good repeatability, linearity with an error of 2.95± 0.40%, and maximum hysteresis error of 2.39± 0.17% on the sensing bulb. This well exceeds the required sensitivity range of a touch sensor. In summary, the sensing bulb shows potential for use in prosthetic hands.

Technological advancements in the areas of sample illumination, image acquisition, and image processing have significantly improved the speed and sensitivity of fluorescence microscopy. In particular, light emitting diodes (LEDs) coupled to transistor-transistor logic (TTL) circuits have reduced photo-bleaching and photo-toxicity by limiting sample illumination to the camera exposure time. Unfortunately, many microscopes still rely on bulb-based light sources that cannot be configured with TTL. Moreover, even when TTL is enabled in conventional microscope software, hardware and software delays can still contribute to photo-toxicity and lead to additional delays between subsequent images, introducing errors in time lapse image recordings. The goal of the present article is to highlight the significance of these issues.

This paper discusses numerical simulations of horizontal flow propeller turbines. Static bulbs located before the turbine can be used to increase water velocity and potentially increase the turbine's performance. The blade angle affects the gap between the blades, and this will also affect the performance of the turbine. Numerical simulations were conducted by using software Solid Works Flow Simulation 2016 and by using five blades in a static state. This study aimed to determine the effect of the bulb ratio and blade angle on the propeller turbine characteristics on horizontal flow. Bulb Ratio variations used in this study were 0, 0.4, 0.6, and 0.8, while the angle variations used were 20, 25, and 30 degrees. Each variation was tested at 0.02 m3/second. The results of this study indicated that the bulb ratio 0.6 with the 25-degree blade angle produces the highest torque

We show how small vibrations of a hanging bulb (in response to sound hitting its surface), can be exploited by eavesdroppers to recover sound. We evaluate our method's performance in a realistic setup and show that our method can be used by eavesdroppers to recover songs from a target room containing the hanging light bulb.

In this paper, we consider multi-datastream VLC networks serving dense IoT deployments and propose a "dome bulb" that consists of a multi-LED array with a dome-shaped lens structure to separate each LED's beam for spatial reuse. Each LED has Lambertian irradiance distribution that can be collected and directed to receiver location using a wide field-of-view (FOV) lens system. Within the FOV, each LED's divergence angle is narrowed to improve spatial reuse, which also brings the problem of spotty lighting. We analyze the dome bulb in terms of illumination uniformity and Signal-to-Interference-Noise Ratio (SINR) provided to receivers in the room. We also present a channel model based on the simulated SINR.

Autologous fat transfer is a common technique to refine the contour of the breast after prosthetic augmentation or reconstruction, correcting remaining asymmetries by injecting previously harvested fat tissue with a cannula. Current procedures are often performed without visualization of the cannula at the delivery site and may require subsequent verification of the implant’s integrity. The present paper aims to evaluate the safety of a new bulb tip cannula to be used during breast implant procedures for injecting fat adjacent to a breast implant that reduce the risk of damaging the implant. Two conventional cannulae and 3 bulb cannulae, which have an atraumatic distal tip, were tested in a simulated implant-puncture setting in 3 positions (at 0°, 45°, and 90° of incidence). A Tensile Tester (Instron, High Wycombe, UK) was used to apply force with each cannula device and record the amount of force applied in the attempt to penetrate the implants used, with shell layers having a variable thickness. No implant rupture was observed with the bulb tip cannulae regardless of size or the position in which the cannulae were pressed against the implants. The cannula opening was not impeded and tended to bend instead; 27% of the cases with the conventional lipo-cannulae caused an implant rupture. The bulb tip cannula could enhance the safety of the fat transfer procedure by ensuring no iatrogenic implant disruption and optimal delivery of the fat tissue.

This selection aims to reduce the amount of battery usage as a DC power source.

The major reasons that cause the damage of damper bars in the leeward side are found in this paper. It provides a route for the structure optimization design of a hydro generator. Firstly, capacity of a 24 MW bulb tubular turbine generator is taken as an example in this paper. The transient electromagnetic field model is established, and the correctness of the model is verified by the comparison of experimental results and simulation data. Secondly, when the generator is operated at rated condition, the eddy current density distributions of damper bars are studied. And the asymmetric phenomenon of the eddy current density on damper bars is discovered. The change laws of the eddy currents in damper bars are determined through further analysis. Thirdly, through the study of eddy current distributions under different conditions, it is confirmed that the stator slots and armature reaction are the main factors to affect the asymmetric distribution of the eddy current in damper bars. Finally, the studies of the magnetic density distribution and theoretical analysis revealed the asymmetric distribution mechanism of eddy current density.

We have developed four different ways of exfiltrating data and analyzed them for generality, throughput, efficiency, and stealthiness.

Through the flux characterization of a high flux solar simulator, all directional information of the flux distribution is lost. Therefore, an experimental approach is necessary to restore the directional information. In this study, 13 heat flux maps were experimentally obtained from a 10 kWe Xenon arc solar simulator through an indirect flux mapping technique, implementing the use of one Lambertian target. The formulation of the inverse problem of experimentally determining the intensity distribution at the focal plane is presented. In addition, a Monte Carlo ray tracing in-house code modeling the Xenon arc is developed and used to generate the experimentally obtained flux maps and intensity at the focal plane to be used as a reference. Two intensity interpolation schemes were examined; a zeroth and first-order schemes. It is shown that a first order interpolation unnecessary complicates the inverse problem. The percentage error reduced from 90.9% to 82.6% when changing the interpolation scheme from a first to zeroth-order, in addition to a five times reduction in computational time. Furthermore, a new approach of constraining the formulated system of equations with an equality constraint that works by eliminating some of the intensity values that cannot be traced back to the ellipsoidal reflector is proposed. Therefore, it can be used as a technique to change the ill-conditioned problem to a well-conditioned one, without depending heavily on Tikhonov regularization methods. This new approach provided intensity values at the focal plane with a reduced percentage error from 52.2% to 30.4% for the zeroth-order interpolation scheme.

It is a well-known fact and a much studied problematic that the performance of low-head hydraulic turbines is highly dependent on the runner–draft tube coupling. Around the optimal operating conditions, the efficiency of the turbine follows closely the performance of the draft tube that in turn depends on the velocity field exiting the runner. Hence, in order to predict correctly the performance of the draft tube using numerical simulations, the flow inside the runner must be simulated accurately. Using results from unique and detailed particle image velocimetry (PIV) and laser Doppler velocimetry (LDV) measurements inside the runner channel of a bulb turbine, this paper presents an extensive study of the predictive capability of a widely used simulation methodology based on unsteady Reynolds-averaged Navier–Stokes equations with a k-epsilon closure model. The main objective was to identify the main parameters influencing the numerical predictions of the velocity field at the draft tube entrance in order to increase the accuracy of the simulated performance of the turbine. This paper relies on a comparison of simulations results with already published LDV measurements in the draft tube cone, interblade LDV, and stereoscopic PIV measurements within the runner. This paper presents a detailed discussion of numerical–experimental data correlation inside the runner channel and at the drat tube entrance. It shows that, contrary to widely circulated ideas, the near-wall predictions at the draft tube entrance is surprisingly good while the simulation accuracy inside the runner channels deteriorates from the leading to the trailing edges.

Background: Hand function is an overall indicator of health and is often measured using grip strength. Handheld dynamometry is the most common method of measuring grip strength. The purpose of this study was to determine the inter-rater and test-retest reliability, the reliability of one trial versus three trials, and the preliminary norms for a young adult population using the Baseline® Pneumatic Squeeze Bulb Dynamometer (30 psi). Methods: This study used a one-group methodological design. One hundred and three healthy adults (30 males and 73 females) were recruited. Six measurements were collected for each hand per participant. The data was analyzed using Intraclass Correlation Coefficients (ICC) two-way effects model (2,2) and paired-samples t-tests. Results: The ICC for inter-rater reliability ranged from 0.955 to 0.977. Conclusion: The results of this study suggest that the bulb dynamometer is a reliable tool to measure grip strength and should be further explored for reliable and valid use in diverse populations and as an alternative to the Jamar dynamometer.

Patient A patient of hemimaxillectomy with restricted mouth opening, wearing a hard acrylic bulb obturator encountered difficulty in insertion and removal of the prosthesis. The prosthesis was converted into a open hollow bulb obturator with flexible walls with permanent silicone soft liner for easy insertion and removal. Discussion Patients having acquired maxillary defects due to surgical resection of the maxilla often suffer with difficulty in mastication, swallowing, nasal regurgitation, speech disturbances and poor esthetics. Different types of obturator with various bulb designs most commonly fabricated from acrylic resins together with "acrylic resin plate and/or" metal framework are used to improve the quality of life of these patients by restoring the function. But restricted mouth opening in some of these patients makes it difficult to place and remove the prosthesis with hard acrylic bulb. Fabrication of flexible open hollow bulb and relining of remaining obturator with resilient permanent silicone soft liner makes easy insertion and removal of the prosthesis and also improve the retention by intimate contact of soft liner with the tissues. Conclusion Permanent silicone soft liner open hollow bulb obturator is a novel way for the functional rehabilitation of a hemimaxillectomy patient suffering with restricted mouth opening.

Secondary optical system designed for LED bulb which emits light in all directions was simulated with Energy Star standards. Components of the optical system were LED light source, the cover of the LED bulb and reflector which is to confirm the diffuser plate and LightTools software was used to design the illumination optics. The main points of the secondary optical system design are the location of the LED light source, the shape of the LED bulb cover, the location of the reflection plate, and the scattering properties of the diffusing plate. Mechanism of the LED bulb is that the light emitted from the light source move on to the backward after reflected by the coated light cover from the inside and then the reflected light is scattered by the diffuser plate. The LED bulb was designed to satisfy the standard light distribution and color specifications of the Energy Star(IES LM-79-08).

Daylighting is often integrated into a building as an architectural statement and for energy savings. However, the benefits from daylighting extend beyond architecture and energy savings. Solar bottle bulb is an invention that is highly effective and cost effective enough to be used in huge numbers for those without sources of interior lighting. This invention is very easy and excessively cheap, requires only a bottle, some roofing materials, water and minimal amount of regularly found chemical and no electricity is needed. This paper reviews the critical retrospect of daylighting through the solar bottle bulb perspective. It highlights the need for solar bottle bulbs use within the underprivileged areas of the world and the importance of this invention as a pathway towards sustainability. This paper presents a review on the designs, principles and applications of the invention that have startled the poor people into a new way of life. The review consists of the assessment of journals, books, newspapers, reports and online sources in the field of daylighting and solar bottle bulb.

Harmonics reduce power quality and increase inefficiency. Although light emitting diode (LED) bulb has been considered more efficient than previous bulb technologies; its internal circuits potentially generate additional problems. This paper has surveyed 6 LED bulb samples and measured the harmonics generated by the internal circuits. As a result. 7 Watt type B LED bulb produces the highest 3rd order harmonics current which is incompatible with IEC61000-3-2 Class C. A prototype of LC filter is designed to decrease the harmonic level. The measurement shows that the designed passive filter is able to reduce at least 81.3% of harmonics.

Smartphones can derive position and orientation by decoding the VLC messages from three or more lights. To achieve this goal, VLC based positioning solutions like Luxapose [3] require all the COTS luminaires to be modified. We propose VisualLoc, a system that enables smartphones to derive position and orientation using a composite-bulb which consists of a single modified commodity luminaire attached to a microcontroller and additional ordinary bulbs arranged in some geometric fashion. The modified luminaire flashes rapidly advertising its global coordinates encoded in terms of light intensity changes imperceptible to human eyes. The relative closeness and/or ordering of the bulbs w.r.t the identified smart-bulb can be leveraged to uniquely map the bulbs. A smartphone camera identifies the composite-bulb from a short video feed and decodes its location. Using this information, the global coordinates and orientation of the camera can be obtained with sub-meter level accuracy.

The improved benefits of the general light emitting diode (LED) attracts the automotive lighting industry and as a result many of the higher end cars today are fitted with LED headlight in place of halogen and xenon bulb based headlights. The advantages include higher operating efficiency, compactness and improved bulb life. In this research, a comparison between the halogen and LED based headlight systems was carried out by focusing on their temperature distributions and light intensity illumination. For this purpose, headlights of SUMO Victa, a Multi Utility Vehicle (MUV) from TATA Motors is used. A LED bulb assembly was fabricated using SMD LEDs which was retrofitted into the Victa headlamps by replacing the original halogen bulb. To dissipate the heat produced by LED, a heatsink fabricated from copper sheet and fitted with copper powder was used. LED bulbs are fitted around the heatsink to effectively remove the heat generated during LED operation and control the junction temperature. To evaluate the performance of the fabricated SMD LED bulb and halogen bulb, experiments were carried out to capture the temperature distribution on bulb, inner and outer surface of headlight along with light intensity. The results clearly show that the LED bulb achieves higher light intensity, less power consumption and temperature distribution than a halogen bulb.

Diffuser vane of tubular pump is different with that of the axial flow pump, since the diffusion angle after the impeller is larger than as usual, which is an important part of bulb tubular pump system. By calculating the hydraulic loss of each part of bulb tubular pump system, it is found that the hydraulic loss of diffuser vane is in large proportion of the whole hydraulic loss. For this situation, focuses on the design parameters of diffuser vane such as diffuser vane length, unilateral edge diffusion angle, equivalent diffusion angle are necessary. In this paper, CFD method is used to simulate the turbulent flow in a bulb tubular pumping system with two different diffuser vanes. The three dimensional flow fields in the whole passage of pumping system with different diffuser vanes are obtained. The results show that all the main geometry parameters of the diffuser vane design affect the performances of tubular pumping system, it should be chosen the parameters reasonably based on the actual situation.

This study presents the performance investigation of a rudder bulb-turbine device (RBTD), which is designed to recover the rotational energy into torque to drive a generator inside the rudder. The blade of turbine is designed first by using lifting line theory, which is modified by lifting surface theory. The induced velocities between the forward propeller and turbine are obtained through the surface panel method (SPM). Hydrodynamic performance for the system is predicted by using SPM. An iterative calculation method is used until the hydrodynamic performance of the system converges. Through the design of turbine behind propeller of a large container ship, the influence of rotational speed of turbine on hydrodynamic performance of propeller-turbine system is observed. Then the size of rudder bulb is determined by calculating the influence of rudder bulb geometry on the hydrodynamic performance of the propeller-rudder system. Based on CFD technology, the hydrodynamic performance of the propeller-rudder system without/with RBTD is also simulated, and velocity distribution is observed. The results show that RBTD is successfully designed and as a ship energy saving device is feasible.

The article elaborates the design and construction of automatic light control system. The developed electronic system eliminates the disadvantages of the existing systems by taking date and time from the GPS, as it also gives information about the position of the system. Based on the results the microcontroller calculates and automatically detects geographical area and retrieve relevant data for sunrise and sunset in the area, respectively ensures very precise ON/OFF mode of the lighting system. It doesn't need operator maintenance and initial installation setup. The developed electronic device increases bulb life in result of the dimming effect. On the other hand this decrease of the illumination leads to reduce in the energy consumption.

After a car accident, it is an important forensic task to evaluate the status of the vehicle's lighting at the time of impact. In some cases, the bulb has to be opened up to allow proper examination of the high and low beam filaments. Quartz halogen pressurized bulbs are both rigid and brittle and their internal pressure makes them likelier to explode. This study aimed to develop a more elegant method of breaking halogen bulbs open that would minimize the danger of explosion and the risk of damaging the filaments in the process. As part of the study, several opening methods were tried on multiple pressurized quartz halogen bulbs, such as cutting a groove with a hacksaw or a rotary tool, using a propane torch on the bulb to cut or warm it and then cooling it rapidly. Repeated testing by several examiners has shown that the new method developed in this study is the safest and easiest compared with other established methods.

This paper presents a novel wide dynamic range system to reduce flickering artifact produced by a high speed electronic rolling shutter in a CMOS image sensor. The proposed algorithm removes flicker artifact in the shortexposure image using a correlation between the pair of two differently exposed images to extend the dynamic range. Since the proposed method overcomes the electronic shutter problem in a conventional wide dynamic range imaging system, it can remove the flicker artifact under an alternating current light source such as a fluorescent bulb.

In regular electrical upsetting process, the process parameters were determined by the experience. During working, these parameters were constant and could not be controlled online. In this paper a new proportionate valve and various velocity top anvils, electrical upsetting system is introduced. Based on the bulb temperature measured at the time of operation proportionate valve will vary the upset pressure to obtain the bulb without crack or fold. The control strategy includes two key parts: sensing the temperature and controlling it by varying the power intensity in the circuit through controlling the upset pressure. And the different anvil position and anvil velocity will be used to change the bulb shape based on the valve profile. This control strategy also includes two key parts: Velocity of anvil is directly proportional to height of bulb, in various positions various velocity will be used to form a different shape of bulb without defects.

This study presented a Leap Motion somatosensory controlled switches. The switches were implemented by the relays. The “open” or “short” of the switching circuit were controlled by the sensing of the Leap Motion somatosensory module. The virtual switches on the screen have designed to be 5 circle buttons. When the sensing hand touched the circle buttons virtually, the programming language “Processing” sent the instruction codes to the Arduino MEGA module which gave the “high” and “low” signal to the transistor switches. Therefore, a four-channel Leap Motion somatosensory controlled switching module has been implemented. For testing the module, the bulbs have been connected with the switching module. Consequently, the “light” or “dark” of LED modules can be controlled by touching the virtual buttons on the screen.
