Abstract: A portable probe stand assembly including a hand-held frame, a gravity tilt unit, and a probe holder. The hand-held frame includes a frame body with a cut-out and two gripping handles. The gravity tilt unit includes a movable part that has a pivot portion rotatably connected to the hand-held frame. The movable part tends to pivot due to gravity to turn the portable probe stand assembly to a hand-held state where a portion of an underside abutting surface of the movable part is disposed out of the cut-out. The portable probe stand assembly is convertible from the hand-held state to a usage state where the movable part is leveled via a pivot movement of the movable part upon engaging the underside abutting surface with a surface of an object.

Each first sliding block has a bottom end complementarily engaged to and slidable on the bridge plate of one of the bridge modules. The locking modules are operable to respectively lock or unlock the first sliding blocks relative to the bridge plates.

Abstract: A support fixture is adapted for utilization of a test probe, and includes two pedestals and at least one moveable carriage assembly. Each pedestal includes a spacing block and at least one side plate connected to the spacing block extending in a longitudinal direction. The at least one moveable carriage includes a vertical panel and an adjustable holding device.

Abstract: A method and an apparatus for evaluating an expression embedded inside a communication packet received from an RFID (Radio Frequency Identification) interrogator device are described. The evaluation result may determine a selection with another RFID interrogator device. An RFID data packet may be sent to an RFID interrogator device based on a selection to be associated with the RFID interrogator. A task may be performed based on the evaluation as instructed by a remote RFID interrogator through a command included in the wireless communication packet.

Abstract: A method and apparatus that determine a time window based on a presentation schedule for a multimedia content in response to receiving the presentation schedule is described herein. The multimedia content is played according to the presentation schedule at a predetermined location. During the time window, an interactive user interface pattern is presented within a vicinity of the predetermined location. In response to receiving a user input via the interactive user interface pattern, a reward is generated during the time window.

Abstract: A method and apparatus that select presentation information for an electronic sign wirelessly placed within a proximity of one or more object items are described herein. The electronic sign displays the presentation information. An alert message is determined in response to a signal received from the electronic sign according to objects items in proximity locations of the electronic sign. The determined alert message is sent to the electronic sign to replace the displayed presentation information.

Abstract: A method and an apparatus for determining the proximity between an electronic sign and one or more object items to transmit presentation information to the electronic sign are described. The determination may be based on a signal wirelessly generated from the electronic sign. The presentation information displayed at the electronic sign may describe the one or more object items. Locations of the one or more object items may be determined based on wirelessly received identifiers of the one or more objects items, a portable wireless device, and the electronic sign.

Abstract: The system of the present invention includes a large-zone RFID reader, a plurality of small-zone RFID readers, and a plurality of RFID tags. The large-zone RFID reader covers areas which are not covered by the small-zone RFID readers. The output power of the small-zone RFID readers is controlled by the large-zone RFID reader based on RFID tag operation patterns of the small-zone RFID readers. The system reliability is improved by a method that uses reliable RFID tags, RFID reader beacon signals, and RFID tag's repetitive transmitting signals to detect tag failures. The system security is provided by a method that uses integrated crypto engines in both the RFID tags and RFID readers.

Abstract: An apparatus, a system, and a method for communication between multiple base stations and radio frequency (RF) transponders (RF Tags) is disclosed. A first radio frequency (RF) base station for communicating RF signals with an RF tag communicates external trigger signals with at least a second RF base station, which causes the second RF base station to begin transmission.

Abstract: A method of selecting groups of radio frequency RF transponders (tags) for communication between a base station and the tags. The tags are selected into groups according to a physical attribute of the signal sent by the tags to the base station, or according to the physical response of the tags to a physical attribute of the signal sent from the base station to the tags. Communication with the tags is thereby simplified, and the time taken to communicate with the first tag is markedly reduced.

Abstract: An apparatus and a method of transporting energy from a base station to energize a remote RF transponder having an energy store is described, comprising transporting power in pulses of frequencies chosen from a randomly ordered list of frequencies, wherein the time between pulses when little power is transmitted is less than the time taken for the remote transponder to deplete the energy store.
