Digital Matrix System (DMS) is well known as sound management system that is specifically designed to provide an intelligent solution to meet the high expectation and distinctive demands of latest Public Addressing (PA) System. On the other hand, Digital CCTV System (DCS) is installed separately to expand the capability of moving object visualization. However, the operation of DCS is mutually exclusive to the management range of DMS. So, the development of Multimedia Digital Matrix System (M-DMS) is worth to provide an integrated solution with both DCS and DMS functionality. As a result, a new framework of Multimedia Public Addressing (M-PA) System is proposed. The essential of multimedia support in M-DMS is high-speed digital interfacing technique. In this case, back plane communication technique has been changed from parallel architecture to serial. So, switch fabric would be a good choice for serial back plane design. The communication backbone of M-DMS is designed to be in star topology. Optical fiber is used as physical communication media to provide better performance in transmission speed, bandwidth, electro-magnetic effect, and noise tolerance. Due to the issues of signal integrity in high-speed digital design, a new adaptive channel synchronization algorithm has been developed. The algorithm, named as hybrid-reset algorithm utilizes the nature of asynchronous reset to compensate the drawback of synchronous counter for phase detection. The hybrid-reset algorithm is successfully solved the most well known problem of channel synchronization in data oversampling method. The problem is about the incapability of embedded clock extraction from serial data stream with unpredictable center of data eye. Besides, the algorithm enables an accurate prediction to the center of data eye with an even number of oversampling clock to data rate ratio. This feature is valuable to simplify the process of frequency synthesis. The algorithm is implemented in programmable logic pl

Controlling gripping force and object slippage is one of the main concerns in the prosthetic hand system. This paper describes a basic equation on a gripping force of an object in one dimension that has been formulated, where the time and the acceleration profiles are defined for holding the object securely. An accelerometer and force sensor system has been developed to monitor the gripping force and also sense the displacement of the object slippage. The acceleration when the object slips is observed and is double integrated to determine the velocity and then the distance. Experimental results are presented for the acceleration and the subsequent integrations. Having the necessary components identified, built and tested, the apparatus can be used to investigate automatic control algorithms for secure grips on objects.

Current trend in Integrated Circuits (IC) implementation such as System-on-Chip (SOC) has contributed significant advantages in electronic product features such as high circuit performance with high number of functions, small physical area and high reliability. Therefore, including Built-In-Self-Test (BIST) facility into each subsystem of SOC is considered a good solution. Commonly, BIST structure is based on random test data generation from a Linear Feedback Shift Register (LFSR) due to its simple, small and economical circuit structure. For this reason, development of test pattern" for BIST based on combination of K-map LFSR and deterministic approach could provide one of the solutions to reduce the testing time. This paper describes the test efficiencies based on combination of K-map LFSR features and deterministic test pattern. A parallel multiplier that considered as one of the demanding subsystems is chosen to verify the proposed BIST performance.
