Abstract: A method and apparatus for selectively reading radio frequency identification device (RFID) tags by an RFID reader includes the RFID reader transmitting an interrogation signal at each of a plurality of power levels beginning with a lowest power level and sequentially increasing power of the transmitted interrogation signal to a highest power level. The RFID reader receives, in response to transmitting the interrogation for at least one of the power levels, at least one data signal from each RFID tag within a read zone of the RFID reader, wherein each of the data signals contains stored data corresponding to the RFID tag responding to the transmission of the interrogation signal. The RFID reader selectively reads the stored data contained in the data signals received from the responding RFID tags.

Abstract: Systems and methods are provided for authenticating an input on a touch screen. A method comprises obtaining one or more pressure metrics for an input by a user on a touch screen that is being proffered as that of a known user. Each pressure metric corresponds to a pressure applied to the touch screen by the user at a respective impression location of the input. The method further comprises authenticating the user as the known user based at least in part on the one or more pressure metrics.

Abstract: A system and method to prevent merchandise from being left at a checkout counter includes a first step of entering a checkout area with a group of items having identification tags. A next step includes reading the tags of the items in the group. A next step includes associating the tagged items as a group. A next step includes detecting whether any tagged item is separated from the group. A next step includes generating an alert if any tagged item is separated from the group.
Abstract: Output power of a laser beam emitted by a laser in an electro-optical reader is regulated by storing a killswitch byte in non-volatile memory, and by checking whether the killswitch byte is in a default state or a kill state prior to performing reading. A controller detects a fault condition and responsively changes the killswitch byte to the kill state, in order to permanently deenergize the laser and to maintain the laser permanently deenergized after the killswitch byte has been changed to the kill state.

Abstract: A cable retention mechanism locks an external connector with an input/output (I/O) connector of an electronic device. The mechanism includes a retention housing having a first surface and a second surface opposite the first surface, the second surface adjacent to the device housing when the retention mechanism and the electronic device are coupled to one another. The mechanism includes a retainer including a mounting arrangement defining a channel receiving a cable of the external connector, the mounting arrangement biased to apply a first retaining force to the cable. The retainer includes a biasing member compressing a portion of the mounting arrangement such that a width of the channel decreases as the channel approaches the second surface, the biasing member applying a second retaining force to the mounting arrangement to increase the first retaining force. When tension is applied to the cable, the biasing member increases the second retaining force.

Abstract: An electronic device includes a main antenna and a diversity antenna. The diversity antenna includes a first portion configured to enable a transceiver to receive a signal in a first low-band frequency of four frequency bands. A second portion enables the transceiver to receive a signal in first and second high-band frequencies. A third portion is RF coupled to the first portion when the third portion is connected to ground. The third portion tunes the first portion such that the transceiver receives a signal in a second low-band frequency. A switch is connected between the third portion and the ground. When the switch is open, the first portion enables the transceiver to receive the signal in the first low-band frequency. When the switch is closed, the third portion tunes the first portion to enable the transceiver to receive the signal in the second low-band frequency.
