Patent CA-2042396-C (CA)
Title: Arrangement for processing sensor signals
Inventor: SCHNEIDER GEORG
IPC: G01D3/028
Filed: 1990-09-10
Granted: 1999-11-23
Abstract: The arrangement serves to process sensor signals which are furnished by a measuring sensor and by one or more further sensors. The measuring sensor generates a measuring effect which depends on a physical measured quantity to be determined and on physical disturbance quantities and each further sensor generates a measuring effect which depends substantially only on physical disturbance quantities. The arrangement includes a signal processing circuit which receives the measuring effects as input quantities. By analog processing of the sensor signals the signal processing circuit furnishes an output quantity, the ratio of which to a reference quantity in dependence upon the measuring effects forming the input quantities is governed by a transfer function defined in specific manner. The coefficients of the transfer function are adjustable for obtaining the desired transfer behaviour in dependence upon the properties of the measuring sensor, the influence of the disturbance quantities on the measuring effect of the measuring sensor thereby being compensated and errors in the relationship between the measured quantity and the measuring effect of the measuring sensor being corrected.

Title: Fibroblast growth factor receptors
Inventor: DIONNE CRAIG A
IPC: G01N33/53
Filed: 1991-07-03
Granted: 2006-01-17
Abstract: The complete cDNA cloning of two human genes previously designated flg and bek is disclosed. These genes encode for two similar but distinct surface receptors comprised of an extracellular domain with three immunoglobulin-like regions, a single transmembrane domain, and a cytoplasmic portion containing a tyrosine kinase domain with a typical kinase insert. The expression of these two cDNAs in transfected NIH-3T3 cells led to the biosynthesis of protein of 150 kDa and 135 kDa for flg and bek respectively. Direct binding experiments with radiolabeled acidic FGF (aFGF), basic FGF (bFGF), or kFGF inhibition of binding with native growth factors, and Scatchard analysis of the binding data indicated that bek and flg bind aFGF, bFGF, or kFGF with dissociation constants of (2-15) × 10 -11 M. The high affinity binding of three distinct growth factors to each of two different receptors represents a unique double redundancy without precedence among polypeptide growth factor/receptor interactions. The use of transformed host cells overexpressing flg or bek or biologically active fragments thereof for drug screening is disclosed.

Title: Method for effecting a set change in a winder
Inventor: GANGEMI DONALD C
IPC: B65H18/20
Filed: 1991-09-30
Granted: 1996-06-11
Abstract: A method for effecting a set change in a winder (14) for a papermaking machine, comprises skip-slitting the paper web (W) across the width of the web (W) transversely to the direction of web travel in the winder (14). An adhesive stripe (44, 44') is appli-ed to the web (W) on either side of where the skip-slit (50) is located. The skip-slit (50) and application of the glue is done at a location upstream of the winder (14) to avoid the problems associated with mounting and operating such equipment beneath the winder (14). The paper web (W) is severed by advancing the skip-slit (50) to a position near the 10 o'clock position over the sur-face of a first winder drum (12) where the web (W) is halted and the wound paper roll (R) is urged off its support on the first win-der drum (12) to thereby increase the tension in the web between the wound roll (R) and web (W) supported on the first winder drum (12) to sever the web. The adhesive stripes (44, 44') on either side of the severance are then applied to the wound roll (R) and a new core, and the process is repeated.

Granted: 2003-07-15
Abstract: A driver for a cathode ray tube includes a black level compensation circuit which generates an offset voltage which tracks the current flowing to the output of the driver and therefore the average picture level (APL). The offset voltage is added as a component of the output voltage so as to increasingly shift the output voltage toward black as the APL increases. This compensates for CRT gamma non-linearities and for light scattering effects which might otherwise cause the loss of perceived detail and sharpness in dark areas of a high APL image.      In the disclosed embodiment, the driver comprises a cascode amplifier and the offset voltage generating element includes a capacitively bypassed resistor connected in a reference voltage network connected to the emitter circuit of the lower (common emitter configured) transistor of the cacode amplilfier.

Abstract: Abstract An improved carding process utilizing a brush attached to a cylinder carding machine for inhibiting the buildup of napped fibers.         Mounted just downstream of the transfer region between cylinders where carding takes place, the brush is stationary with respect to the revolving cylinders.  The brush is disposed across the face of the carding drum, with the nylon bristles of the brush engaged in the card-cloth wires of the drum.  The bristles continuously brush, straighten and force napped fibers down into the wires of the carding cylinder, which results in a thicker, heavier web of carded fibers and virtually eliminates buildup of fluffy fibers on the carding drum as well as the input drum.

Abstract: A composite synchroniza-tion extraction circuit is particu-larly suited for receiving compo-site video signals containing closed captioning data in raster scan line (21) by means of a sig-nal CMOS integrated circuit de-vice. A dual mode voltage clamp is realized in CMOS technology. The clamp includes temperature compensated current sources in the form of complementary cur-rent mirrors through which a clamped composite synchroniza-tion node is charged and dis-charged with the aid of a compar-ator, the output of which controls a transistor for charging the com-posite synchronization node. De-tected pulse amplitude is set by slicing (24, 25) the incoming pulse at the back porch level and then doubling the amplitude with an amplifier and comparing that level with the back porch level as derived from a sample-and-hold device. Frequency and phase synchronization is accomplished by a combination of frequency lock Loop and phase lock loop (27, 28) working in concert to generate a control voltage for a voltage controlled oscillator in a. flywheel mode. The voltage con-trolled oscillator (27) is not subject to noise in the incoming signal and provides a clean source of timing information for the cir-cuit.

Abstract: A CDMA signal receiving apparatus for a base station is disclosed. The apparatus is characterized by a spread-spectrum demodulation section which has a plurality of channel-signal processing sections and a common-signal processing section.

Abstract: The retransmission of signaling messages that data terminals (e.g., modems) might exchange prior to exchanging user data is controlled by arranging a data terminal that receives multiple copies of the same signaling message so that it saves only the first copy thereof, but transmits a response to the sending terminal following receipt of each such copy. The sending terminal terminates its transmission of the signaling message upon receipt of a response from the receiving terminal. The inventive procedure is especially advantageous for controlling theretransmission of signaling messages during a n-way handshake between two terminals.
