The long form housing frame securely frames the handheld computing modules when the variable form keyboard is configured as the long form keyboard, and the short form housing frame securely frames the plurality of computing modules when the variable form keyboard is configured as the short form keyboard.

Abstract: A docking cradle for a portable electronic device has a floating connector assembly which isolates a portable electronic device connected to the connector assembly from at least some of the shock, vibration or other motion imposed on the rest of the docking cradle. The connector assembly is positioned above a base frame and comprises a platform, a device interface on the platform, a device securing mechanism connected to the platform and connectable to the portable electronic device to physically secure the portable electronic device to the connector assembly; and at least one connector assembly spring connecting the connector assembly to the base frame such that the connector assembly is movable laterally relative to the base frame.

Abstract: A keypad bezel for attaching to a housing of a handheld computer comprises a main body including plurality of screw holes and tabs for connecting the main body to the computer housing and a plurality of leverage points in the main body useful for removing the keypad bezel from the housing. To remove the keypad bezel, the screws are removed from the screw holes and a removal tool is positioned so that it mates with recesses the keypad bezel and force is applied to the removal tool in a direction way from the housing. The force removes the tabs out of corresponding slots in the housing allowing the bezel to be removed.

Abstract: A multi-field antenna able to receive a signal over one field selected from a plurality of different fields of the antenna includes an interface to connect the antenna to a signal processing device, such as an RFID reader, to receive and process the signal. The antenna includes a first magnetic loop configured to be tuned by a first tuner to provide a first volume field for reading data; a second magnetic loop configured to be tuned by a second tuner to provide a second volume field for reading data, the second volume field being smaller than the first volume field; and a switch to configure the first tuner and the second tuner to select the one field from the plurality of fields. The multi-field antenna can have a wide volume field selected to detect items within a large area and then the multi-field antenna can be switched to select a smaller volume field to detect items within a substantially smaller area.

Abstract: A computing device and method for reading a barcode captured with a color image sensor is disclosed. The barcode can have features and background that have equal brightness such that the barcode could not be decoded with known greyscale decoding techniques. The method for reading the barcode includes receiving color image values for each pixel of a captured image of a target barcode from a color image sensor, determining chrominance values for each pixel from the color image values, detecting edges based on the chrominance values to generate an edge-detected image that is provided to a greyscale barcode decoder to decode the information in the target barcode. The chrominance values can be based on the blue and red difference components from the YUV image format, and the U and V values can be combined using color temperature information.

Abstract: A battery module mount for securing a battery module to a housing of a handheld device, including one or more latch elements attached to the housing and movable between a free position and an unlatched position, with a tab portion, and one or more elongate resilient elements biasing each latch element to the free position. Each latch element is positionable in a latched positions. The mount also includes one or more mating means attached to the battery module with an abutment with which the tab portion is engageable when the latch element is in the latched position, to hold the abutment in a retainable position, thereby securing the battery module to the housing. The tab portion is disengaged from the abutment when the latch element is in the unlatched position, to permit removal of the battery module from the housing.
