Title: Wash durable fabric laminates
Inventor: DUTTA ANIT
IPC: B32B7/14
Filed: 1997-03-25
Abstract: A delamination problem in fabric laminates made of a fabric laminated to a non-porous, hydrophilic organic polymer film, such as a breathable polyurethane film, was found to be caused by the hydrophilic nature of the polymer. A  particular adhesive pattern was devised to overcome the delamination problem.  More specifically, a wash-durable fabric laminate of a continuous, non-porous hydrophilic polymer, e.g., a breathable polyurethane, layer and a fabric layer were bonded together by a discontinuous, but interconnected pattern of an adhesive layer. The fabric laminate is water-vapor-permeable, air-impermeable and liquid water impermeable.

Abstract: A trellis-coded modulation (TCM) decoder of a high-definition television (HDTV) receiver for a US-type terrestrial broadcasting, and a decoding method thereof.  The TCM decoder includes:  a segment sync suspension unit for directlyconnecting the data before and after 12 symbols from a segment sync when as input HDTV signal has passed through as NTSC rejection filter (8-state case), and for passing the input HDTV signal unchanged when the input HDTV signal has not passed through the NTSC rejection filter (4-state case); a field delay for directly connecting the data of the data segment just before the field sync segment to the data of the date segment just after the field sync segment; and a Viterbi decoder for decoding the output of the field delay in both an 8-state case and a 4-statecase.  Therefore, decoding is performed in consideration of the effects of uncoded segment sync and field sync signals, thereby achieving stable decoding.

Title: Profile key operator system - pko
Inventor: GEVA GABRIEL
IPC: G06Q30/02
Filed: 1998-10-08
Abstract: The PKO is a suggested solution and a way to provide a rather targeted advertisements to the consumers and to the companies to have their Ads exposed as much as possible to the most well defined targeted group of people. Today the Ads are running by the special date and time... the advertiser has made the contract for and thus he is exposed only to those people watching or using that media at that time...some of the existing Ads are given in some "specific"  sites so as to provide a better targeted exposure... while in the PKO system the Ads will be targeted to the pre-screened & pre-evaluated prospective consumers and thus the benefit is by far and large better and has the expected value of a rational input to the Ads... [fig. No. 1] Using the PKO provides almost an unlimited frames of time/date for the Ads to be exposed as at any particular time/date frame given... a great number of Ads can be exposed as they would be directed to the appropriate pre-evalueated consumers....and thus each consumer will be exposed to the appropriate kind of Ads he most likely to be interested in....and thus all the 'participants" are getting a better service and a better value for their time/money formula... The basic idea is providing a system that would be able to provide the Ads according to a rather very dynamic formula that might convey a well defined and targeted Ads on the electronic media - particularly over the Internet machines as well as all the Cable-TV used all over the world! [Fig. No. 2]  The PKO is a specific key encoded with some specific data derived from a well prepared Questionaire that will provide different User/Consumer sections that will lead to the different machines - namely computers hooked to the Internet, or the Cable-TV- the well defined Ads and thus all the participants will be pleased in getting a better service from the huge media of the Internet and the Cable TV.

IPC: H01L29/78
Filed: 1997-07-04
Abstract: The invention discloses a high frequency MOS transistor structure with an extended drift region, which modulates the resistance in the drift region of the MOS transistor. The extended gate layer is obtained by an extra semiconductor layer forming a second MOS structure on top of a thin gate oxide layer. The electrical field will then be uniformly distributed laterally in the extended drift region. This design makes it possible to produce a MOS transistor with a short channel length and an extended drift region with low doping concentration and still having very low on-resistance together with a high breakdown voltage.
