Abstract: Bushings and methods of manufacturing bushings to be used in a chassis of a vehicle or the like for damping and absorbing vibrations, oscillations, and noise are provided. In one implementation, a method of manufacturing a bushing includes the steps of positioning a flexible member around a cylindrical outer surface of a rigid inner member having a cylindrical inner surface or solid core and positioning an outer member having a cylindrical inner surface around the flexible member. The method also includes the step of clamping a cylindrical outer surface of the outer member to form an indentation in the cylindrical outer surface of the outer member, thereby deforming the flexible member. This method may be executed to create a bushing having certain axial, radial, and torsional stiffness.

Abstract: A linear LED lighting system, assembly and/or fixture distributes luminance efficiently in certain applications, such as for ceiling lighting used in certain retail environments. According to example embodiments of the invention, a linear LED lighting system includes at least two tilted, parabolic reflecting surfaces and a linear array of LED devices, wherein at least some of the LED devices are substantially disposed at a focus line of at least one of the tilted, parabolic reflecting surfaces. A diffuser or diffusive lens can be disposed adjacent to the parabolic reflecting surfaces where light exits the system to provide color mixing and/or eliminate potential hot spots. The tilt of the reflecting surfaces can be changed to adjust the illumination pattern. A lighting system according to example embodiments of the invention can be designed for retrofit installation or as a complete fixture.

Abstract: Methods for sharing service identity between client devices in a real-time communications network are presented including: registering a first client device with a server on the real-time communications network, the first client device registering with a shared service identity, where the first client device becomes an active client device; and when a second client device enters a physical proximity of the first client device; establishing a personal area network connection between the first client device and the second client device; registering the second client device with the server, the second client device registering with the shared service identity, where the second client device becomes the active client device and the first client device becomes a waiting device, where the waiting device discontinues communication with the server.

Abstract: Methods for providing full duplex media service over a communications network employing simplex media paths are presented including: establishing a simplex media path and session over a terminal using a communication protocol; establishing an additional simplex media path and session over an additional terminal using the communication protocol; and utilizing the simplex media path and session with the additional simplex media path and session to provide full duplex media service between the terminal and the additional terminal. In some embodiments, after establishing the additional simplex media path and session, processing media on the additional terminal. In some embodiments, the communications network is a Push-to-Talk over Cellular (PoC) network and the simplex media path and session and the additional simplex media path and session are Push-to-Talk (PTT) sessions.
