摘要： An aftertreatment device for reducing nitrogen oxides (NOx), particulate matter (PM), hydrocarbon (HC), and carbon monoxide (CO) generated by a compression-ignition (CI) engine. In this device, lean exhaust air generated in the CI engine is converted to rich exhaust air, and energy used for the conversion is recycled using an energy recovery device. The result rich exhaust air then pass through an oxidation catalyst, where NOx is reduced with CO and HC.

摘要： An RFID device having sensor arrays incorporated in its tags. Each tag generates an ID code together with sensing pulses the width of which changes with sensing values. Conflicts between tags in communication are avoided by adding a sleep section to the code sequence. The interrogator reads the ID code and digitizes the width of sensing pulses during the communication with tags, and then calculates sensing values based on the information obtained. Since only discrete signals exist in data acquisition, and the digitization process is in parallel with data communication, the system needs neither ADC circuits nor an extra process for signal digitization.

摘要： A radio frequency identification device having sensing elements incorporated in its tags, and the sensing value determines the width of a sensing pulse in its RFID code. Through a pulse-processing unit, during communication, digital sensing values are obtained by measuring the width of the sensing pulse. Since only discrete signals exist, the tag device is insensitive to the fluctuation in its power supply voltage, which is derived from a continuous wave RF carrier.
