Title: Digital demodulation
Inventor: BROWN GEOFFREY BRIAN DONALD
IPC: H04L7/04
Filed: 1993-04-02
Abstract: A method of demodulating an oversampled digitised analogue signal F(t) wherein n samples per bit of the digitised signal represent the instantaneous frequency and/or phase of the signal. The method includes the steps of selecting a sequence of bits containing bit value transitions, determining the magnitude of F(t) within the sequence so that all the extrema are maxima (or minima), whereby the maxima (or minima) of ¦F(t)¦ provide a defined timing position in relation to the bits of the sequence. The value of ¦F(t)¦ over a succession of said bits is averaged and a timing control signal is derived therefrom for demodulation of the digitised analogue signal. Applications include TDMA radio systems. <IMAGE>

Title: Radio channel selection method
Inventor: OWADA JUNICHI
IPC: H04W72/00
Filed: 1995-03-08
Abstract: A mobile radio communications system comprises a mobile station which can operate in either a full-rate TDMA or a half-rate TDMA mode. When a call is set up, the mobile terminal transmits a signal indicating that communication can be performed in either of the two modes. A radio base station receiving the signal checks whether there is a channel available in a first of the two modes and if there is sends a signal designating the channel to be used. If there is no channel available, the base station checks whether there is a channel available in the second mode and, if there is, sends a signal designating the channel to be used. If no channel is available in either mode a clear-forward signal is transmitted. <IMAGE>

Title: Multi-colour head-up display system with corrected colour aberrations
Inventor: GOHMAN JEFFREY A
IPC: G02B27/01
Filed: 1996-05-24
Abstract: A multi-color optical display system 10 employs a multi-powered reflective combiner 20 that together with a monochromatic or partly color-corrected relay lens 16 longitudinally corrects a multi-colored image. The combiner typically includes two surfaces 82, 90 of different optical powers with a reflective coating 106, 108 on each of the surfaces. The coatings are chosen to each reflect a specific wavelength range of colored light used in the system and to transmit all other wavelengths. The curvature of each surface is dictated by the aberrations in the color image created by the relay lens 16. Specifically, each surface is positioned so that its focus (86, 94, Fig. 3) coincides with the focal point (58, 60, Fig. 3) of the corresponding color component in an intermediate image 18 created by the relay lens so that the final virtual image 22 reflected by the combiner is longitudinally color corrected. The plan view also shows image source 12 and pilots aye reference point 23. Coating 106 is preferably holographic.
