  • Patent number: 8063800
    Abstract: An encoding method comprises generating a character map of an alphanumeric character string, identifying runs of like character type symbols in sequential positions, and removing the runs of character type symbols from the character map. The center for the center infix run is determined, and the characters of each character type are encoded into binary encoded substrings. A decoding method comprises parsing the one or more run fields in the alphanumeric header to determine a number of characters of each type of a plurality of character types represented in the binary encoded string, generating a character map having a string of character type symbols representing the binary encoded string, including determining a reduced character map, centering the character type symbols for a center infix run about the center of the reduced character map, completing a final character map, and decoding each binary encoded string.

  • Patent number: 8033149
    Abstract: A technique is provided for determining estimated location of a wireless communication device (WCD) in a network. A first AP transmits a first RSSI data request message, including a BSSID to the WCD at a first time over a radio channel. The WCD then transmits a first response message to the first AP, which then transmits a first measured RSSI value to a trilateration engine (TE). At a different, second time, a second AP can switch to the radio channel and transmit a second RSSI data request message that includes the BSSID of first AP to the WCD over the radio channel. In response, the WCD transmits a second response message to the second AP, which then transmits a second measured RSSI value to the TE. A third AP performs a similar message exchange. This technique collects RSSI information from the WCD at the APs without disrupting any of their connections.

  • Patent number: 8033472
    Abstract: A bioptical workstation includes plural image capture modules for capturing images of indicia along different fields of view. Each module includes an illuminator for illuminating the indicia with illumination light, a megapixel imager with a rolling shutter for sequentially capturing the return light, and a shutter element for passing the return light to its imager in an open state, and for blocking the return light from other modules from reaching its imager in an closed state. A controller prevents interference among the modules by controlling the shutter element to assume the open state only during a respective exposure time period during which its imager produces an electrical signal indicative of the indicia, and by controlling the shutter element to assume the closed state at all times other than the respective exposure time period to prevent capture of the return light from the other modules.
