Title: Method of operating a communications system, a communications system anda secondary station for use in the system
Inventor: OWEN FRANK CHARLES GWYN
IPC: H04M1/72516
Filed: 1991-12-11
Granted: 2002-01-29
Abstract: A communications system, such as DECT, comprises a plurality of geographically separate primary (or fixed) stations (PS) and a plurality of secondary (or portable) stations (SS) which are able to roam relative to the primary stations. Communication between the primary and secondary stations is by way of any one of a plurality of TDD radio channels. A primary station when idle transmits an idle beacon signal onto which an idle primary station can lock by scanning the radio channels. However a secondary station which has roamed out of coverage range of the primary stations can save battery power by progressively increasing to a maximum time value the time interval between successive scans.

Title: Vehicle engine ignition timing system and method with windowing knock control
Inventor: WITKOWSKI MICHAEL ROBERT
IPC: F02P5/152
Filed: 1992-04-03
Granted: 1995-12-19
Abstract: An ignition timing system activates combustion ignition apparatus in a combustion chamber at times established at least partly in response to a knock retard value.  The knock retard value is normally modified in response to a knock signal generated by a knock sensor during a knock window corresponding to a predetermined crankshaft rotational angle in which knock is to be sensed.  However, if the knock signal is determined to be present at the beginning of an occurrence of the knock window, modification of the knock retard value in response to the knock signal is prevented during that occurrence of the knock window, since a knock signal already present at the beginning of the knock window is assumed to be noise.

Granted: 2007-04-03
Abstract: The invention relates to methods and mutation linkers to modify DNA, to methods for producing libraries containing a multiplicity of modified DNA, and to methods for using such libraries for screening modified proteins encoded by such DNA. The DNA targeted for modification typically encodes a polypeptide such as an enzyme.

Abstract: A video transmission apparatus that has a first input terminal for receiving a low-resolution TV signal. The apparatus also has a second input terminal for receiving a high-resolution TV signal and for outputting the high-resolution TV signal. The apparatus converts the low-resolution TV signal into a signal having a format which is equal to that of the high-resolution TV signal. The apparatus selects either the signal, which has been produced by converting low-resolution TV signal into a signal having a format which is equal to that of the high-resolution TV signal, or the high-resolution TV signal, which is outputted from the second input terminal. The signal which has been produced by converting low-resolution TV signal into a signal having a format which is equal to that of the high-resolution TV signal, is fitted into the high-resolution TV signal. The apparatus encodes the selected signal into a digital high-efficiency coded signal, and outputs a signal indicative thereof. Finally, the apparatus transmits the signal produced by encoding the selected signal.
