Abstract: A method in a Radio Frequency Identification (RFID) system including at least one reader/writer and a group of tags each attached to a workpiece. The method includes reading a plurality of tags from the group of tags, capturing received signal strength indication envelopes of tags, and storing the received signal strength indication envelope one tag as a template. A correlation match is performed for the received signal strength indication envelope of the tags and the template to obtain a time interval between the received signal strength indication envelope of each of the tags and the template when the correlation is at a maximum value. Using the present invention, the at least one reader/writer can report each tag that is directly in front of an antenna, even if multiple tags exist in the complicated industrial environment, ensuring First Come First-Read (FCFR) and improving the reliability of an ultra high frequency RFID system.

The rotation speed control circuit provides a rotation speed control signal. The voltage transforming circuit is electrically connected to the rotation speed control circuit and transforms the rotation speed control signal to a speed control voltage signal. The buffering circuit, electrically connected to the voltage transforming circuit, receives the speed control voltage signal and delays or buffers output of the speed control voltage signal. The driving circuit, electrically connected to the buffering circuit, receives the speed control voltage signal from the buffering circuit and generates a driving signal according to the speed control voltage signal so as to control the operation of the motor.

Abstract: A reader and method for adjusting the transmission time of a continuous wave (CW), wherein the method comprises setting an initial value for a response waiting time, sending the CW to a tag after sending a command to the tag and waiting for a response from the tag, judging whether the response from the tag is received within the response waiting time. If the response from the tag is received within the response waiting time, then sending of the CW is stopped and the response waiting time is adjusted. If the response from the tag is still not received beyond the response waiting time, then sending of the CW is stopped. The time for the reader to wait for a response from the tag is far less than 20 ms. Consequently, a command failure can be found early, so as to improve the processing efficiency of an RFID system.

Each pair of the adjusting elements are fitted into receiving spaces of a corresponding pair of left and right covers such that teeth formed on each pair of the adjusting elements mesh with teeth formed in the corresponding pair of left and right covers. Each pair of the left and right covers have a side provided with guide grooves for receiving a sliding element coupled to the windshield. Thus, the windshield coupled to the frame units can be conveniently raised, lowered, or tilted to provide the desired shielding effect. The motorcycle windshield assembly is flexibly adjustable in height and tilt angle and is collapsible when not in use.

Abstract: An apparatus, system and communication method, which is particularly suited for a radio frequency identification system (RFID), wherein a reflection-transmission apparatus is disposed in a radio system and, during a communication process, the reflection and transmission features of reflection-transmission apparatus presented at the radio frequency are changed to introduce a multi-path signal component which changes with time. Consequently, during the communication process, a receiving apparatus receives and combines the multi-path signal component of communication signals and the radio system performs communication by utilizing time diversity effects. The apparatus, system and method provide effective and continued reduction of communication blind spots in the RFID system, thereby improving the overall success rate for the RFID system to read tags and accomplishing a better balance with the overall reading time.

Abstract: Monoclonal antibody reagents that recognize the SARS-coronavirus (SARS-HCoV) are needed urgently. In this report we describe the development and immunochemical characterization of mAbs against the SARS-HCoV based upon their specificity, binding requirements, and biological activity. Initial screening by ELISA, using highly purified virus as the coating antigen, resulted in the selection of seventeen mAbs. Five mAbs exhibited Western immunoblot reactivity with the denatured spike protein, of which two demonstrated the ability to neutralize SARS-HCoV in vitro. Another four Western immunoblot-negative mAbs also neutralize the virus. These antibodies will be useful for the development of diagnostic tests, pathogenicity and vaccine studies.
