The present invention discloses a fuel-cell-based cogeneration system with radio frequency identification (RFID) sensors. The fuel-cell-based cogeneration system with RFID sensors includes the fuel-cell-based cogeneration system and an RFID data processing system. The RFID data processing system captures data of the temperature and flow rate from the RFID sensors, while the system data are in turn converted into RFID signals. The RFID data processing system transmits a control signal generated from the RFID signal to control the operation of the fuel-cell-based cogeneration system. Since the RFID transmission technology, the sensor error caused by wires is consequently reduced. Furthermore, overall sensitivity and accuracy of the RFID sensors are increased, which leads to an accompanying increase in the stability of the operating system.

A power module is proposed to package an electronic system having flip chip power MOSFET devices. The power module includes a front surface cover board and a multi-layer printed circuit laminate bonded thereto. Notably, the front surface of the printed circuit laminate includes recessed pockets each having printed circuit traces atop its floor. Inside the recessed pockets are power MOSFET and other circuit components bonded to the printed circuit traces. As the circuit components are encased inside the power module, it features a low profile, an increased mechanical robustness and EMI/RFI immunity. Additionally, some circuit components can be provided with a front-side bonding layer that is also bonded to the front surface cover board to realize a double-side bonding to the interior of the power module. Methods for making the low profile power module are also described.

By taking advantage of parallel data processing and transmission techniques, the data access rate of a redundant array of independent disks (RAID) level 5 can be boosted significantly. A data distribution and aggregation unit is utilized to distribute a data stream into a plurality of data sub-streams based on the primitive data access block of storage devices as a processing unit of data writing, or to aggregate a plurality of data sub-streams to form a data stream based on the primitive data access block of storage devices as a processing unit of data reading. An exclusive OR operation unit capable of parallel data processing is introduced for performing data processing on the plurality of data sub-streams simultaneously. The data transmission of each data sub-stream is controlled individually by one of a plurality of transmission controllers.

A class-D amplifier includes a ramp generator to provide a ramp signal having a frequency varying with an audio input signal, and a modulator to convert the audio input signal to a pulse width modulation signal according to the ramp signal for a driver to drive a load device. The varying frequency of the ramp signal will cause the frequency of the pulse width modulation signal unfixed and consequently improves EMI issue.

A reusable bio-analysis cartridge that includes a built-in mechanism to track various parameters and usage data. The tracking mechanism includes a non-volatile rewritable memory “smart-key” that is associated with the cartridge to provide automatic tracking dedicated to the cartridge. The key may be physically coupled to the cartridge with good high voltage insulating properties. When the cartridge is used in an instrument, the associated key is inserted into an I/O interface to communicate with the instrument. The instrument may be configured to “authenticate” the cartridge and conduct an integrity check to determine if the particular cartridge has the correct properties (e.g., gel-chemistry, serial no., Patient I.D.) for the particular sample analysis to be conducted. Further, the instrument may communicate/record information concerning usage of the cartridge (e.g., usage history, test parameters, and perhaps test results). Such information provides an update to the stored information from the previous use of the cartridge.

A test sample collection device includes a generally elongated sample collection section for collecting and holding a test sample, a handle member having a top half, a bottom half, a test strip located between the top and bottom halves, and an opening formed by the top and bottom halves, and a cap. Prong members fit within the opening of the handle member for releasably connecting the sample collecting section to the handle member. The cap is releasably mounted on the sample collecting section and covers the sample collecting section. Flexible extension members on the cap are used to release the sample collecting section from the handle member. The collecting section includes a plurality of fins and slots for assisting in collecting the test sample. The device also includes windows for magnified viewing of test results and for indicating whether a sufficient amount of the sample has been collected.

摘要:
A method is disclosed for defining discrete magnetic and non-magnetic regions on the magnetic film layer of a storage media substrate. The method applies anodic oxidation of a cobalt-containing magnetic film layer to remove cobalt, followed by controlled deposition of a non-magnetic matrix into the regions where the cobalt has been removed. Deposition may either be electrodeposition, collimated vacuum deposition, or other methods depending upon the composition of the non-magnetic matrix being deposited. The method may be performed in a single electrochemical cell.
