  • Patent number: 11480471
    Abstract: An infrared temperature sensor comprises a first communication port and a second communication port. A plurality of infrared temperature sensors can be cascaded to each other and connected to an external host controller through the second communication port. The external host controller can set up and administer the unique addresses of the plurality of the infrared temperature sensors through the second communication port, whereby to selectively perform multicasting communication or unicasting communication with the plurality of infrared temperature sensors through the first communication port. The infrared temperature sensor further comprises a second thermopile sensing element used to sense the thermal radiation of a package structure, whereby to compensate for the measurement error induced by temperature variation of the package structure. Thus, the measurement accuracy is increased.
    Type: Grant

  • Patent number: 7860008
    Abstract: A method for receiving data is provided. Multiple packages are received according to a sliding window W(N). If a starting package of the packages is received successfully, the W(N) is slid to a W(N+1). If a non-starting package of the packages is received successfully, the corresponding counter is activated for counting. If the starting package of the packages is not successfully received and part of multiple counters counts to an up-limited value, the W(N) slides to the W(N+1). Other packages are continuously received according to the W(N+1), and whether the block sequence numbers (BSNs) of the counters located in the overlap area between the W(N) and the W(N+1) are determined. When at least one BSN to which at least one counter corresponds is not located in the overlap area, the at least one counter corresponding to the at least one BSN not located in the overlap area is reset.
