Title: Emulating an advanced control algorithm in a mobile communications system
Inventor: FRIED TOMAS
IPC: H04W60/00
Filed: 1998-02-03
Abstract: An illustrative embodiment is described herein, whereby a packet switched system (16, 20) emulates the location algorithm of a circuit switched system (14, 18). The packet switched system (16, 20), wherein cell reselection (1) is performed primarily by the mobile stations (20), has advanced locating and flexible cell reselection capabilities that cause the packet switched traffic to behave (from a control standpoint) virtually the same, with respect to cell reselection and locating, as the circuit switched traffic. In other words, the packet switched mobile terminals (20) are able to emulate the locating functions of the circuit switched system, which minimizes signal interference (40) between the two systems (14, 16, 18, 20). More broadly, the present invention enables one type of mobile communications system (16, 20), which utilizes a less advanced radio network control algorithm, to emulate the more advanced radio network control algorithm of a second type of mobile communications system (14, 18), which enables the two system's traffic to behave virtually identically in the same radio network environnement (10).

Title: Retro-reflective sign
Inventor: BALINT GREGORY J
IPC: E01F9/619
Filed: 1999-09-22
Abstract: A retro-reflective sign is formed of a lens plate bearing indicia and having a front face and a rear face. The rear face is formed with a plurality of adjacent cube corner configurations having central axes, which configurations may reflect light rays approximately parallel to incoming light rays. The front face can be formed with adjacent rows of prisms that are saw-tooth shaped in cross-section. The prisms overlap the configurations and are shaped to bend incoming light rays towards the axes of their respective overlapped configurations and to re-bend the reflected light rays parallel to the incoming light rays. The lens plate is bowed so that its front face is convex and its rear face is concave. A rearwardly bowed support plate covers the rear face of the lens plate and the two plates are secured together along their peripheral edges for rigidifying the sign. The rear plate may be sufficiently light transparent to pass some light therethrough to backlight the indicia on the front plate.
