Abstract: A portable electronic device includes a housing, a sensor array including a first camera module having a first field of view, a second camera module having a second field of view different from the first field of view, and a light source, and a rear cover formed from a glass material and defining a raised sensor array region positioned over the sensor array. The raised sensor array region defines a first hole extending through the rear cover and positioned proximate a first corner region of the raised sensor array region, and a second hole extending through the rear cover and positioned proximate a second corner region diagonal from the first corner region. The first camera module includes a first camera housing defining a recess at a corner of the first camera housing, and the second camera module includes a second camera housing extending into the recess.

Abstract: A method and system for assembling framed display items is provided. The method includes: a) providing a substrate feeder and controlling the substrate feeder to dispense a first substrate; b) using a first robotic actuator to pick the first substrate and move it from the substrate feeder to an assembly station; c) locating the first substrate to a predetermined position on the assembly station; d) using a second robotic actuator to pick a frame from a frame station and move the frame to the assembly station. The second robotic actuator moves the frame from the frame station to the assembly station with the frame oriented such that the frame is placed over the first substrate residing at the assembly station and the first substrate is disposed within a frame rabbet; and e) installing fasteners within the frame to secure the first substrate within the frame rabbet.

Abstract: Briefly, the above and further objects of the present invention are realized by providing a portable wireless communication unit having an electronic communication device with an integrally formed U-shaped frame housing mounted externally thereto. A power pack for supplying electrically power to the communication device, is adapted to be mounted removably latchably within the frame housing. The power pack includes an apparel clip mounted externally to one of the power pack faces for enabling the communication unit to be supported from the wearing apparel of a user. A resilient spring finger disposed on the power pack is latchably received within a groove disposed in the frame housing, to retain releasably, the power pack in a confronting relationship within the frame. An integrally formed flange forming part of the power pack, cooperates with an elongated slit-like groove in the frame housing to facilitate the proper alignment of the power pack when received within the frame housing.

Abstract: The optical transceiver includes a headset antenna assembly, which is adapted to be worn on the head of the user, and which is connected electrically by a cable to a transceiver unit adapted to be worn on the belt of the user. The headset antenna assembly includes a set of alternating light emitting diodes and photosensitive diodes which are disposed on the antenna assembly to transmit and receive optical signals about a substantially 360 degree radial axis. The light emitting diodes are inclined upwardly from a horizontal plane to help avoid obstructions. Baffles are disposed between the diodes to reduce feedback interface, and a circuit in the transceiver unit discriminates against background light.

Abstract: A communication headset has an earpiece assembly mounted on one end of an arcuate headband having a single-piece integral, unitary construction and a resilient composition. The earpiece assembly includes an earmuff which engages a user's ear and which receives a speaker and speaker holder. The speaker holder is mounted rotatably to an interface module which in turn is mounted to a microphone module. An end cap engages the interface module and the microphone module. The mounting structure for attaching the microphone module to the interface module enables free 360.degree. rotational movement of the microphone module relative to the interface module about a central axis transverse to the interface module. A temple piece is disposed on the opposite end of the headband for engaging the user's temple.

Abstract: A method of testing the implementation of a communication system definition by constructing a model of the communication system definition in a high level computing language such as PL/1; compiling the model and producing an executable machine language program; monitoring and recording messages transmitted by the data communication system; extracting relevant message-related information; using the extracted message unit sequence as input data to the executable machine language program; executing the machine language program and using the results of the execution to give an indication whether or not the messages were constructed correctly according to the communication system definition.
