Patent CA-2161998-A1 (CA)
Title: System for televoting
Inventor: SCHINKEL DOLF ALBERT
IPC: H04N7/173
Filed: 1995-11-02
Abstract: System for televoting, in which home audiences may transmit televotes in response to a radio or television programme by means of a televote terminal to a central processing system. Driving the televote terminal by a (broadcasted) radio or television signal makes it possible to centrally program the televote terminal, e.g., from the studio. In this manner, the televote terminals may be provided with the desired transmission parameters, which would otherwise have to be set by the home users. The ease of use is also considerably improved, as more simple response codes may be used. Finally, central driving of the televote terminals results in additional, interactive user-options.

Inventor: MCCORMICK FRED B
IPC: C09J4/02
Filed: 1994-06-15
Abstract: A composition of matter includes a polymerizable mixture comprising 1 to 99 weight percent of a first monomer and an initiator therefor, the first monomer being one of 1) at least one free-radically polymerizable monomer or 2) at least one cyanate ester monomer, and 99 to 1 weight percent of a second monomer and an initiator therefor, the second monomer being the member of 1) or 2) that is not selected as the first monomer, wherein the curative for the cyanate ester is a transition metal-containing organometallic compound curing agent and the curative for the free-radically polymerizable monomer is a free-radical generating curing agent or a transition metal-containing organometallic compound. The polymeric mixtures are useful, for example, in applications requiring high performance, such as high temperature performance; in composites, particularly structural composites; structural adhesives; vibration damping materials; electronic applications such as printed wiring boards, semiconductor encapsulants and electronic adhesives; photoresists; injection molding and prepregs; protective coatings; tough self-supporting films; and high performance binders. In addition, a curable composition comprising two partially polymerized mixed syrups of ethylenically unsaturated monomers is provided. These compositions are useful as the precursors for vibration damping materials. Further, a curable composition including (1) an ethylenically unsaturated monomer or (2) an ethylenically unsaturated monomer and a cyanate ester monomer, and certain organometallic neutral compounds is useful in the graphic arts.

Patent CA-2177414-A1 (CA)
Inventor: KROON PETER
IPC: G10L25/90
Filed: 1996-05-27
Abstract: A speech coding system employing an adaptive codebook model of periodicity is augmented with a pitch-predictive filter (PPF). This PPF has a delay equal to the integer component of the pitch-period and a gain which is adaptive based on a measure ofperiodicity of the speech signal. In accordance with an embodiment of the present invention, speech processing systems which include a first portion comprising an adaptive codebook and corresponding adaptive codebook amplifier and a second portion comprising a fixed codebook coupled to a pitch filter, are adapted to delay the adaptive codebook gain; determine the pitch filter gain based on the delayed adaptive codebook gain, and amplify samples of a signal in the pitch filter based on said determined pitch filter gain. The adaptive codebook gain is delayed for one subframe. The pitch filter gain equals the delayed adaptive codebook gain, except when the adaptive codebook gain is either less than 0.2 or greater than 0.8., in which cases the pitch filter gain is set equal to 0.2 or 0.8, respectively.

Title: Selection of Terminal Equipment in Response to a Data Message Received During Silent Intervals of Ringing
Inventor: BROWN EDWIN ZANE
IPC: H04M1/715
Filed: 1996-05-30
Abstract: Responding by telecommunication terminal to data messages received during the silent intervals of ringing to immediately answer a call, perform monitoring activities, provide selective answering of incoming calls, and perform control functions. For providing selective answering, telephone sets utilizing the invention monitor the incoming data message to determine if an identification code of the telephone set is contained within that message. If the identification code of the telephone set is within the message, the telephone allows ringing at that set. If the identification code of the telephone is not in the data message, the telephone counts the number of ringing cycles, and, once this count becomes greater than apredetermined number, the telephone set allows ringing at the set. For performing monitoring activities, a remote utility meter reader is responsive to it's identification code in a data message to immediately answer the incoming call from a public utility company computer before ringing starts. After answering the call, the meter reader establish a communication session with the public utility company computer to allow the transfer of utility usage to the public utility computer. Similarly, fax, computers, and answering machines are responsive to their identification code in a data message to immediately answer the call. In addition, for performing controlfunctions, a control unit utilizing the invention recognizes its identification code and additional data to either turn on or turn off some device connected to the control unit.

Title: A capacitive pressure sensor having a reduced area dielectric spacer
Inventor: PROVENZANO PAUL L
IPC: G01L9/00
Filed: 1995-01-26
Abstract: A silicon capacitive pressure sensor is disclosed that has a glass dielectric material sputter-disposed  onto a silicon substrate of the sensor.  After deposition of the bulk dielectric material, the glass is patterned and etched to form a pair of  concentric rings.  An inner ring is of a circular shape, while the outer ring is of an octagonal shape.  As compared to prior art dielectric spacers which are  of a single ring of relatively wide  thickness,  the pair  of concentric  rings disclosed  herein significantly reduce  the parasitic capacitance of  the glass  dielectric material, thereby increasing the sensitivity of the sensor.
Patent CA-2182540-A1 (CA)
Inventor: LEICHTY DERYLL L
IPC: B65G59/06
Filed: 1996-08-01
Abstract: The apparatus of this invention comprises a tray destacking station, a part unloading station, and a tray stacking station arranged sequentially adjacent and connected by a pallet transport system and a tray transport system. This system is designed to move a pallet containing a stack of fully loaded trays into the destacking station, raise the dunnage and suspend the stack over the pallet. The pallet is then removed from the bottom of the stack. In a similar manner the stack is then raised and suspended over the bottom tray to allow it to be moved into the unloading station. After the parts are removed from the tray, the tray is moved into the stacking station where it is positioned underneath the stack of empty trays. This is accomplished by providing a lift at the destacking and stacking stations which raises and lowers the stack in operative association with racks that engage, suspend, and release the stack to allow the trays to be separated from the bottom of the stack.

Title: Apparatus and method for bingo card management
Inventor: GILGEOUS EARLE
IPC: A63F3/06
Filed: 1995-09-22
Abstract: The issue of bingo paper is controlled by producing packages of multiple sheets each including multiple bingo cards, with each card provided with a uniformly located machine readable index number, the index number of cards on a sheet, and on sheets within a package being related to each other and to a matrix of numbers appearing on each card such that the index number of each card uniquely identifies a number matrix appearing on that card, and that of other cards within the sheet, as well as the sheet and package to which it belongs, checking each package into inventory, machine reading the index numbers of sufficient of said cards as they are sold to identify which cards have been sold, and placing the said cards in play. Verification of cards is provided by machine reading the index number of a card claimed to be a winning card, verifying that it is a card in play, and identifying the number matrix carried by the card to verify that it is a winning card. Multiple cards can be identified at a time as they are sold by measuring the dimensions of a part sheet of cards to determine the numbers of cards therein and their positional relationship to a card at one corner of the part sheet, and matching reading the index number of the card at that corner to identify the cards transferred from stock to play. The index numbers are typically in the form of barcodes.
