Abstract:
A weapon system is provided. The weapon system includes a receiver and an operating group. The operating group includes a barrel extension at least partially housed within the receiver and arranged to axially translate relative to the receiver; an operating rod (op-rod) assembly arranged to axially translate within the barrel extension; and a bolt assembly arranged to axially translate within the barrel extension. The system further includes a gas accelerator coupled to the barrel and the op-rod assembly; a buffer assembly including a self-centering spring and a hydraulic piston assembly having a first end coupled to the receiver and a second end coupled to the barrel extension; and a feeder coupled to the receiver and configured to provide the round to the operating group.
Abstract:
Provided is a light emitting semiconductor device that includes a substrate having a first area having a first height and a second area having a second height different from the first height, wherein the first area supports at least a first light emitting semiconductor (LES) and the second area supports at least a second light emitting semiconductor (LES).
Abstract:
A variable speed electromagnetic motor (69), generator or dynamic brake includes a rotor (52) and a stator (56), both mounted for rotation with respect to a reference element. A drive shaft is coupled to one of the rotor and the stator, and a controlled variable load is coupled to the other of the rotor and the stator. This variable load reacts against the reference element to apply a variable torque tending to retard rotation of the other of the rotor and the stator. In this way the speed of the drive shaft and the power transmitted by the drive shaft are controlled. Another variable speed electric motor, generator or dynamic brake includes a rotor having a rotor gear (74) and a stator having a stator gear (76). A gear or gear assembly (76) is coupled to the rotor gear in a manner to form a mechanical differential that causes the rotor and the stator to rotate in opposite directions, when the gear assembly is rotated.

Abstract:
A wireless presentation system includes communication means for line-of-sight communication links such that an association between a content holder and a desired presentation device can be automatically established using line-of-sight communication links.
Abstract:
A presentation request and delivery system includes a client device and a presentation system. In some cases, the client device is configured to send a request for at least part of the presentation being presented on the presentation system, where the request includes an audience identification. In some other cases, the client device is configured to obtain a device identification of a presentation device via a line-of-sight communication interface and send a request for at least part of the presentation, where the request may include an audience identification and at least part of the device identification. Upon receiving the request, the presentation system will verify whether the request is authorized using the audience identification and deliver the at least part of the presentation requested if the request is authorized.
