This paper presents a high-sensitivity passive wireless humidity sensor system with a portable telemetry unit for applications in sealed environments. A complementary metal oxide semiconductor (CMOS) interdigital capacitive humidity sensor die was attached to an organic substrate (FR-4) on which a fixed planar spiral copper inductor was fabricated. The variable capacitor and the fixed inductor were wire bonded to form an inductor–capacitor ( LC ) tank circuit. The resonant frequency of the sensor tank is dependent on the sensor capacitance, which changes in response to the humidity. The sensitivity of the capacitive sensor was improved significantly using graphene oxide as a sensing material. The package-level integration was achieved by employing the embedded inductor on an organic packaging substrate. The LC -type sensor is interrogated wirelessly using our homemade portable telemetry unit, which is based on a standing wave ratio bridge to measure the real part of the readout coil impedance. Measurements show a sensitivity of −18.75 kHz/%RH over a range of 15%–95% RH. The implemented telemetry unit addresses the need for a low-cost, portable, and universal reader of the LC -type passive wireless sensors. [2013-0188]

Radio telemetry is used in many remote monitoring and remote control applications, such as in environmental monitoring, pollution monitoring, weather forecasting, and other applications. In typical applications sensors are used to collect data and this data is then transmitted to a remote receiving station where it is analysed. This paper outlines the basic principles of the radio telemetry systems and gives an example to show how such a system can be designed and used in teaching the principles of radio telemetry. The designed system is based on a popular microcontroller.

The modern world is increasingly reliant on technology and consequently the systems which power it. Portable power systems are used in a wide variety of applications to varying degrees of success. Within the power range of 10 – 5000W the current power systems are not adequately ‘portable’. Thus the aim of this thesis is to recommend chosen portable power systems which are best suited to certain portable power applications.A comprehensive, critical analysis of relevant portable power systems; micro combustion engines, fuel cells and batteries has led to accurate recommendations being made on the benefits of each in various portable power applications of unmanned aerial vehicles, military services, personal electronics and portable generators.An extensive literature review has been undertaken and research compiled on the previously stated portable power applications and portable power systems. From this research, a relevant assessment framework was created to perform a comparative analysis of each power system. Using a multi-criteria decision making analytical hierarchy process, a matrix of criteria necessary for portable power applications was made presenting weightings for each criteria, quantifying their importance. A ranking system was defined to enable each power systems features in relation to each stated criteria to be ranked. Multiplying the weightings and rankings together resulted in weighted rankings for each power system in relation to each portable power application.Analysing the results obtained from the assessment framework indicated that micro combustion engines were best suited to all portable power applications. Batteries were a close second in all applications and fuel cells ranked significantly lower than both of these systems in all applications. Whilst micro combustion engines are not currently commercially available, they have incredible potential in the portable power market, and if research and improvements continue they will be a preferred choice to a battery in future. Currently batteries are still the best product on the market for portable power applications due to their maturity and commercial success.It is recommended that in future the further criteria be established and a wider range of rankings used to improve the accuracy of results. It is also recommended that in future the data the rankings are based off be updated, as fuel cells and micro combustion engines are a quickly improving technology whose features will change in future.

Telemetry data frame structure is complicated and changeable, so telemetry pre-processing software cannot be universal. To solve this problem, a component method was proposed in this paper, which can effectively compensate for the deficiencies of the traditional method. XML files were employed to configure telemetry parameters, including the information of appropriate processing method for data processing. Based-on memory-mapped telemetry source data extraction can greatly improve source extraction speed, and data integrity is guaranteed by sub-frame data fusion. Subsequent telemetry software developing shows that the method can improve the reusability of pre-processing module and shorten the system development time.

In this paper, the effective information transfer technique between computing device and portable device that is connected through USB interface has been studied. The proposed technique is realized by the method which portable device is perceived into optical media such as CD-ROM or CD-R/W through SCSI commands on USB interface. Through the proposed system in this study, we maximized user convenience by executing diverse works using stored data in a portable device without installing extra USB driver corresponding to portable device, when user data is transmitted between computing device and portable device. We conducted experimental tests to verify the performance of the proposed system through implementing of test system. As a result, we confirmed the technique is comparatively superior to existing method in transmitting speed and user convenience.

Research is underway to develop instruments and methods to determine the activity of radionuclides present in the fallout debris from the detonation of a radiological dispersal device (RDD). Handheld instruments, including commonly used health physics survey instruments, have been incorporated into a portable telemetry kit containing a global positioning system receiver, WiFi and radio communications, and a small microcomputer to facilitate data processing, logging, and transmission. An operator carries the system and walks through the RDD post-blast environment, real-time radiological data is logged, stored locally, and transmitted to a base station outside of the RDD hot zone. A map of the distributed radiological dispersal is generated, subdividing the world into 1-m2 squares. Separate measurements of ground activity taken at a finite number of discrete locations is used to cross-correlate the survey data, transforming the health physics data (e.g., mrem hr−1) to surface activity (Bq m−2). The map data, smoothed using standard Kriging approaches, is then analyzed by summing each discrete square area, producing an estimate for the total dispersed ground activity. The instrumentation and method have been field tested multiple times at Idaho National Laboratory during field exercises using short-lived radionuclides detonated in small-scale experiments.

The most rational scenarios for strategies for constructing and developing on-board telemetry systems and software-hardware means for the telemetry complex of a space-vehicle launch site are determined on the basis of previous research and a problem-oriented morphological analysis.

Compact flash(CF) memory for data storage media, USB interface for data downloading, and a software for operating status diagnosis and file format conversion are used.

Measurement of the energy cost of walking in children with cerebral palsy or spina bifida is difficult due to the cumbersome nature of equipment used to assess oxygen consumption. Such information collected with a lightweight telemetric system, the Cosmed K2, correlated well with that from a non-portable breath-by-breath system associated with a treadmill. The K2 did not significantly affect regular gait pattern as measured by gait analysis, and repeatability was satisfactory. Measurement of the energy cost of walking in the individual is unreliable in detecting differences of less than 10%; comparison between groups is more useful.

The third purpose of the system is to serve such a flying relay station for scenarios that LOS or range limits between ground station and vehicle under test could not be achieved. Such maneuvers performed at low altitude or out of range for receiving antenna on ground could be examples.

In recent years, with the boom of BCI (brain-computer interface, BCI) research, a multitude of researchers have begun to study control system based on BCI. However, the existing brain control systems still have some problems: bulky acquisition devices, cumbersome to use, expensive and difficult to communicate. So it is difficult for the existing brain control systems to be used in situations such as wearable artificial limbs and battlefield equipment, which needs portable control device.

This paper describes an electronic system for telemetry and control applications of distributed systems. It consists of a portable electronic circuit (portable module) that can be connected up to various types of sensors depending on the application to be used in each case, together with a mobile-telephony communications system. Different portable modules can be used to build up a communication network governed by a central control unit (personal computer and communications system); communication can be established from the control centre with any portable module for sending or receiving information; it is also possible to modify the application programme executed in each portable module by the teleprogramming of the microcontroller system built into the latter circuit.

In these times of Faster, Better, Cheaper (FBC) spacecraft, Spacecraft Operations Automation is an area that is targeted by many Operations Teams. To meet the challenges of the FBC environment, the Mars Global Surveyor (MGS) Operations Team designed and quickly implemented two new low-cost technologies: one which monitors spacecraft telemetry, checks the status of the telemetry, and contacts technical experts by pager when any telemetry datapoints exceed alarm limits, and a second which allows quick and convenient remote access to data displays. The first new technology is Automatic Alarm Notification (AAN). AAN monitors spacecraft telemetry and will notify engineers automatically if any telemetry is received which creates an alarm condition. The second new technology is Web Telemetry Display (WTD). WTD captures telemetry displays generated by the flight telemetry system and makes them available to the project web server. This allows engineers to check the health and status of the spacecraft from any computer capable of connecting to the global internet, without needing normally-required specialized hardware and software. Both of these technologies have greatly reduced operations costs by alleviating the need to have operations engineers monitor spacecraft performance on a 24 hour per day, 7 day per week basis from a central Mission Support Area. This paper gives details on the design and implementation of AAN and WTD, discusses their limitations, and lists the ongoing benefits which have accrued to MGS Flight Operations since their implementation in late 1996.

Telemetry is an important function of the Internet of Things as it is being developed and deployed today. Of particular interest within this area are energy monitoring services. In this paper we describe Watts App, a social telemetry gathering and comparison platform, which was built as a demonstrator that integrates technologies from embedded systems to mobile applications. We used the SNMP protocol stack developed for the Contiki embedded operating system to retrieve telemetry information from a hardware interface that reads data from S0 meters (e.g., power meters, fluid meters). A web interface and an Android mobile application lets users view this data. To ensure privacy of users' data, it is only stored at users' own premises and all communication takes place over encrypted connections. This paper provides an overview of the implementation of Watts App.
