Abstract A standalone ambient light sensing device was constructed by interfacing a sulphided Cuprous Oxide (Cu2O)thin film semiconductor based photo-sensor. The photo-sensor was custom fabricated by depositing n-type Cu2O on a titanium substrate followed by a sulphidation process that formed a Cu2O/CuxS thin film semiconductor heterojunction. Evaporated gold contacts were placed on top of the film. The photo-sensor was operated in the... A standalone ambient light sensing device was constructed by interfacing a sulphided Cuprous Oxide (Cu2O)thin film semiconductor based photo-sensor. The photo-sensor was custom fabricated by depositing n-type Cu2O on a titanium substrate followed by a sulphidation process that formed a Cu2O/CuxS thin film semiconductor heterojunction. Evaporated gold contacts were placed on top of the film. The photo-sensor was operated in the photovoltaic mode and once interfaced to the device, the sensor photovoltage was further amplified and measured through a 10-bit analog to digital voltage converter embedded in a microcontroller. A liquid crystal display was interfaced to the microcontroller to display measurements. Data logging was done directly to the available microcontroller flash memory or through a RS-232 serial communication link to a PC. The sensor was sensitive to a broad range of intensities (0 – 120,000 lux) with a fast photo-response time on the order of a few hundred milliseconds. The available extra micro controller ports could be utilized for device control and feedback by interfacing other suitable electronics. The total cost of parts for the device was less than US$25.

Abstract Experimental approaches used for architecture exploration and validation are often based on configurable logic device such as FPGA. NoC architectures require multi-FPGA platforms as the resources of a single FPGA are not big enough. Partitionning a NoC on multi-FPGA requires special techniques for allocating communication channels, physical links and suitable resource allocation scheme. We present a scalable emulation platform and its... Experimental approaches used for architecture exploration and validation are often based on configurable logic device such as FPGA. NoC architectures require multi-FPGA platforms as the resources of a single FPGA are not big enough. Partitionning a NoC on multi-FPGA requires special techniques for allocating communication channels, physical links and suitable resource allocation scheme. We present a scalable emulation platform and its associated design flow based on a multi FPGA approach that allows quick exploration, evaluation and comparison of NoC solutions. The efficiency of our approach is illustrated through the deployment of the Hermes NoC and its exploration on several FPGA platforms. Read More Read Less

Security risks exist in fireworks production and storage and there have been many accidents in the past few years. The introduction of chain management for fireworks industry is currently a new exploration and it is the new development trend of this industry. Using environmental monitoring system and the indoor positioning and tracking system based on RFID technology for real-timely monitoring the people walking paths and production environment, the processes among production and storage would be safer and easily avoid accidents. At the same time, it can improve the management style and increase the profits of enterprises, for improving the quality of products and reducing the administration cost. Read More Read Less
