Title: Airbag folded by draw threads.
Inventor: BAUER WOLFGANG
IPC: B60R21/232
Filed: 1997-06-17
Abstract: Folding threads 10,11 have one end fastened to seam 4, loose connections to the top 2 and bottom 3 layers of fabric and a portion accessible from outside the bag.

Title: Channel estimation in a variable data rate communication system
Inventor: TOSKALA ANTTI
IPC: H04W28/22
Filed: 1997-11-03
Abstract: In a communication system with variable data transmission rates, data is transmitted as a plurality of data symbols over a sequence of time slots each time slot having at least a proportion containing data symbols depending on the transmission rate of the slot. A rate estimator estimates the transmission rate in each slot from received data symbols. The estimated transmission rate is used for channel estimation. Thus channel estimation based on data can be used where there are poor signal to noise ratio, discontinuous or no pilot signals. Also rate information specifying the transmission rate, encoded in the received data channel or in a separate control channel can be verified. The estimated transmission rate can also provide a Viterbi decoder with additional information for rate based decisions.

Title: Block cypher resists differential or linear cryptoanalysis
Inventor: LEE CHANG HYI
IPC: H04L9/06
Filed: 1998-06-04
Abstract: A block cipher algorithm is based on the prior Feistel type block cipher algorithm (or similar to DES algorithm). Usually the security of a Feistel type block cipher algorithm depends on the structure of its round function. More specifically, this disclosure relates to the round function structure of the Feistel type block cipher algorithm, in the instance that the round input data block is divided into 8-bit blocks and the divided sub blocks are fed, with the combined output data of the previous S-box, into 256 x 8 S-box, except for the first input sub-data block. The first sub-data block one is directly fed into the first S-box. The total output data block, after these steps, is rotated by 8-bits and this rotated result is the output of the current round function. This is to resist linear and differential cryptanalysis.

Title: Establishing communication in a computer network
Inventor: EIBACH WOLFGANG G
IPC: G06F21/31
Filed: 1998-09-12
Abstract: Provided are apparatus and a method for establishing communications between a Web client computer in a vehicle and a Web server computer connected to the Internet or an intranet, initiated from a remote Web Browser. The Web Browser sends a request to the server, which invokes a process at the server causing a SMS message to be sent to a telephone connected to the client computer. This SMS message includes an identification of the server process (such as a URL) and causes the client computer to establish communications with the server. This allows the Browser to interact with the client computer via a standard Browser request without the overheads of security exposure of requiring the client to be a Web server. The invention is useful for allowing a remote Browser to interact with a computer controlling a vehicle's electronic control systems.

Title: Focus voltage tracking circuit
Inventor: GEORGE JOHN BARRETT
IPC: H04N3/26
Filed: 1999-06-18
Abstract: A direct current focus voltage FV applied to a focus electrode 17 of a cathode ray tube 10 that produces a blue image is set to slightly defocus the blue image for increasing the blue beam spot size. The increase in the blue beam spot reduces the saturation and allows brighter blue and increased blue video drive rage. A passive network 25, 26 including a capacitor 25 is coupled between a ultor electrode 14 and the focus electrode 17 to tracking of focus voltage-to-ultor voltage ratio. A dynamic focus correction signal DF is coupled via a capacitor 24 to the focus electrode 17. The tracking prevents voltage fluctuation of the ultor voltage produced by video loading from disturbing uniform defocussing in the entire blue image.

Title: A CMOS data receiver with insensitivity to common-mode voltages
Inventor: KURD NASSER A
IPC: H03F3/45
Filed: 1999-11-01
Abstract: The input stage of a CMOS data receiver comprises an inverter 518,520 with active loads 502,508. When the reference voltage is relatively high, the PMOS active load 502 sources more current to match the current sunk by NMOS input transistor 520. When the common mode voltage is low, the NMOS active load 508 sinks more current to match the current sourced by PMOS input transistor 518. Rising and falling delay times are insensitive to the reference voltage. The source and sink transistors 510,512 are connected to the current mirrors 502,504 and 506,508 to provide self-biasing.
