Title: Liquid crystal display device
Inventor: TAKASHI AKIYAMA
IPC: G09G3/36
Filed: 1994-04-08
Abstract: This invention contemplates to make a liquid crystal display device compact by reducing the number of input terminals of a scanning electrode driving circuit or a signal electrode driving circuit. A scanning direction is determined from the relation of the polarity of a sequential scanning start signal (TPR) and a sequential scanning timing signal (CK) in a scanning electrode driving circuit. A transverse direction of output data is determined from the relation of a display data latch signal (CL) and a signal electrode driving voltage output signal (CL2) in the signal electrode driving circuit. Accordingly, the number of input/output terminals necessary for the scanning electrode driving circuit or the signal electrode driving circuit is reduced, and the liquid crystal display device can be made compact. <IMAGE>

Title: Compensating for motion in satellite telephone handset
Inventor: HUTCHINSON BEN
IPC: H04W64/00
Filed: 1997-09-06
Abstract: A satellite communications system, where a satellite 10 passes messages between a user terminal 44 and an earth station 38 as the satellite moves in an orbit 12 12', includes means for measuring the position of the user terminal by means of Doppler shift measurements and propagation delay measurements between the single satellite 10 and the user terminal 44. If two or more satellites are used, only Doppler shifts or only propagation delay measurements need be used. Apparant position errors, due to movement of the user terminal 44 relative to the surface of the earth 14, inducing its own Doppler shift, are compensated by iteratively estimating the velocity and position of the user terminal 44 starting with a best guess for the user's velocity. The specification also discusses the optimum number of measurement to use to optimise the accuracy of the position estimate.

Title: Method for enabling the locking of a mobile phone hand set to a specified network by the network operator
Inventor: COOPER DAVID EDWARD
IPC: H04M1/66
Filed: 1998-03-18
Abstract: A secret number is embedded in the hand set 1 through the SIM interface in the locking process. The hand set can then only be used with that SIM from that network operator. The secret number is stored in a non volatile memory 2 in the handset. When the operator wishes to unlock the phone from the network,the SIM 4 instructs the handset to generate a random number. This is then used in combination with the secret number as inputs to a random challenge authentication algorithm such as the GSM A3 algorithm. This function is calculated in the handset. The random number is transmitted to the SIM, which also calculates the value of the function. Only if the value returned by the SIM matches the internally generated value will the handset reverse network lock. The secret number may be transmitted over the air interface.

Title: Method and architecture for simplified communications with HID devices
Inventor: RAY KENENTH D
IPC: G06F3/038
Filed: 1998-07-29
Abstract: A computer system in accordance with the invention includes a USB transport layer and an HID class driver implemented on top of the transport layer. A client program calls the class driver (either directly or indirectly) to obtain HID reports and report descriptors. Before returning the reports to calling programs, however, the HID class driver normalizes the reports by making them a uniform length and by adding report IDs to any reports that do not already have report IDs. A provided parser includes a descriptor parsing function and an item retrieval function. After obtaining a report descriptor, a client calls the descriptor parsing function with the report descriptor as an argument. The descriptor parsing function returns a data structure containing a parsed report description. The client stores the parsed report description and submits it, along with HID reports, to the item retrieval function. A particular usage specification is also provided as an argument to the item retrieval function. The item retrieval function searches the designated HID report, based on the parsed report description, and returns one or more data items from the report whose usage specifications match the usage specification submitted as an argument to the item retrieval function.
