Patent CA-2045270-A1 (CA)
IPC: H04M1/663
Filed: 1991-06-21
Abstract: A method and apparatus for processing incoming telephone calls includes structure and process steps whereby an incoming telephone calling signal having a data message associated therewith is received.  The data message is processed to determine whether it is a first type of message or a second type of message.  An alert signal is output only if the received data message is determined to be a first type of message. Preferably, the alert signal is a ring signal, and the first type of message is an ICLID message indicating the identification of the telephone call initiator or calling party.  If the incoming signal is detected as an ICLID PRIVATE signal, the phone ringer will not be activated, an off-hook signal will be returned to the caller, and a display device will indicate that the received call is an ICLID PRIVATE phone call.

Title: Adjustable, elastic static control wristband
Inventor: WEISS JOHN W
IPC: A61N1/14
Filed: 1991-08-22
Abstract: An adjustable, elastic wristband for dissipating the buildup of excess electrostatic discharge from an individual. The wristband has two straps or strap sections, one electrically insulative and the other electrically conductive, and at least one of the two straps or strap sections being elastic. A connector case provides the electrical connection between the conductive strap and a conductive grounding tether. Various clasps are used to adjust the insulative strap or strap section.      In each of the disclosed alternative embodiments, the wristband may be adjusted for comfort without requiring trimming of the excess strap material which is pulled through the clasp, and without otherwise exposing any conductive portions of the wristband, since the excess adjusted material is electrically insulative and thus may be left dangling.

Abstract: This invention provides a moldable fiber reinforced resin sheet which is suitable for preparing a fiber-reinforced resin molding having excellent coloured conditions.  The invention also relates to a method for producing the sheet.  The moldable sheet of the present invention comprises a fiber-reinforced resin layer and a coloured surface resin layer laminated to the first layer and has, in the fiber-reinforced resin layer, a fiber-reinforced coloured resin layer adjacent to said surface resin layer.  The fiber-reinforced coloured resin layer is coloured in a colour similar to that of the surface resin layer, and has a fiber-reinforced transparent resin layer arranged on the surface of the side opposite to the surface resin layer.  The transparent resin layer being curable with ultraviolet radiation.  The first method for producing the sheet comprises carrying out a viscosity-thickening treatment on a resin layer first laminated out of the fiber-reinforced coloured resin layer and fiber-reinforced transparent resin layer.  The second method for producing the sheet comprises forming a fiber-reinforced transparent resin layer and, on this layer, laminating a fiber-reinforced coloured resin layer without the viscosity-thickening treatment on the transparent resin layer, and then, laminating a surface resin layer, if necessary, after carrying out viscosity-thickening treatment on the fiber-reinforced resin layers.  The third method for producing the sheet comprises forming a surface resin layer and carrying out a viscosity-thickening treatment on this layer, and independently, after forming a fiber-reinforced transparent resin layer, on this layer, laminating a fiber-reinforced coloured resin layer without the viscosity-thickening treatment on the transparent resin layer, and then, laminating the surface resin layer on the fiber-reinforced coloured resin layer.

Abstract: A new architecture of an ATM or ATM/STM switching node which is functionally equivalent to the classical buffer-space-buffer  (BSB) architecture is disclosed.   In the basic embodiment, it uses middle packet buffers with a rotator (commutator) at its input and output.  It has two main advantages over the BSB architecture.  First of all, in the ATM mode, the need for arbitration when more than one inlet competes for the same outlet during the same time slot is eliminated.   Each packet knows when to proceed without being aware of the competing packets. This greatly simplifies the switching-control mechanism. Secondly,  the  switch hardware  complexity is reduced through the use of  clock-driven rather  than state-controlled cross points.  The cross-point ratio is 4/?n, where n is the number of inlets (outlets).

Abstract: A system and method for processing image data from a document and for producing a compressed binarized version of the image data for transmission to or use by subsequent users.  Processing of the image data is done in parallel after the scanning of the document is started but before the entire document is scanned.  A splitter is used to divide a scan line of image data produced by an imager at the scan line into a plurality of channels, with each channel having at least one overlap area of pixels and with the overlap areas of pixels being used to avoid errors between channels.  Thresholding and compression are performed by each one of the channels in parallel. The compression is performed in a direction which is perpendicular to the direction of scanning and conforms to a standard compression algorithm like CCITT Group 4.

Title: Method of forming a channel estimate for a time-varying radio channel
Inventor: LARSSON LARS G
IPC: H04B17/00
Filed: 1992-08-13
Abstract: ABSTRACT            Radio signals are transmitted over a fading radio channel and are filtered and sampled in a receiver to obtain a digital signal (y(n)). A channel equalizer (5) has an equalizing filter (CEST) in which a channel estimate (h(n/n-L)) is formed with the aid of a known synchronizing sequence. A Viterbi analyzer (VIT) decides symbols (d(n-L)) with the aid of the channel estimate. An es-timated time derivative of the channel estimate (h(n/n-L)) is formed and adapted with the aid of the decided symbols (d(n-L)). The channel estimate (h(n/n-L)) is adapted to the radio channel by the derivative estimate and the decided symbols (d(n-L)). In the event of fading with rapidly varying signal strength (y(n)), the channel estimate (h(n/n-L)) is adapted slowly and is predicted mainly through the derivative estimate which varies relatively evenly. The digital signal (y(n)) is stored in a memory (M) and an initial value is formed for the derivative estimate as a dif-ference between two known channel estimates divided by a time difference therebetween. The known channel estimate may belong to two separate synchronizing sequences  or may belong to one synchronizing sequence and a fading time point in which the channel estimate has zero value.

Title: Positive temperature coefficient start winding protection

Filed: 1992-12-11
Abstract: A protection circuit for a permanent split capacitor motor includes a positive temperature coefficient (PTC) resistor in series with the auxiliary winding of the motor for protecting the auxiliary winding during normal operation.  At a predetermined temperature anomaly due to over-current conditions in the windings, the PTC resistor will sharply increase its resistance to a point wherein no current will pass, effectively open circuiting the auxiliary winding from the power source, thereby protecting the windings from damage.  A thermally responsive protector may also be used in conjunction with the PTC resistor for providing further over-current protection to both the main and auxiliary windings.
