Patent CA-2102500-A1 (CA)
Inventor: POKLEMBA JOHN J
IPC: H04B1/10
Filed: 1992-07-16
Abstract: A pre-averager for digitally averaging the samples of an input data signal (26) over two or more symbols, the averaging interval being defined by the input sampling rate divided by the output sampling rate. As the averaged sample is clocked (290, 29e) to a suitable detector at a much slower rate than the input signal sampling rate the noise bandwith at the input to the detector is reduced. The pre-averager forms a data filter (50a, 50b, 50c, 50d) having an output sampling rate of one sample per symbol of received data. More specifically, selected ones of a plurality of samples accumulated (28a, 28b, 28c, 28d) over two or more symbol intervals are output in response to clock signals at a rate of one sample per symbol interval.      The pre-averager includes circuitry (40, 44) for weighting digitized signal using stored finite impulse response (FIR) filter coefficients (42).

Title: Inhibition of tumor cell growth by administration of b7-transfected cells
Inventor: CHEN LIEPING
IPC: A61K45/00
Filed: 1993-10-01
Abstract: The present invention is directed to a method of inhibiting tumor cell growth. Tumor cells from a pateint are recombinantly engineered to express the B7 surface protein and these cells are then readminsistered to the pateint. The presence of the B7 molecule on the tumor cell surface stimulates a broad immunologic response against both the B7-transfected and non-transfected tumor cells and results in the immunologic killing of localized and metastatic tumor cells. B7 transfection of the tumor cells, or cell membranes, serves as a stimulant to engender a potent immunologic response against the surface antigens present on the tumor cells.
Patent CA-2109192-A1 (CA)
Inventor: CHAN DOUGLAS W
IPC: G06F13/00
Filed: 1993-10-25
Abstract: In a telecommunications management network including a network element provisioned as a so-called Directory Services Network Element (DSNE) and at least one sub-network intended to include one or more network elements, the DSNE automatically distributes the identity information of all network elements in a sub-network to all the network elements in that sub-network. Specifically, the DSNE automatically distributes all the identity information for all network elements within a sub-network to a newly registered network element and also supplies the identity information for the newly registered network element to all the other network elements within the sub-network. Since, each sub-network can be defined as a set of network elements that require significant communications with each other, distribution of the identity information for all the network elements in the sub-network to all the network elements in that sub-network significantly reduces the number of queries made to the DSNE. Furthermore, in the event of a DSNE  failure, the network elements in a sub-network may still be capable of communicating with each other, thereby improving communications survivability. (FIG. 1).

Patent CA-2113250-A1 (CA)
Inventor: TOPPER JEFFREY
IPC: H04L12/24
Filed: 1994-01-11
Abstract: A connection-oriented congestion controller for a common channel signaling network comprises a memory for storing data representative of established connections, and a data transceiver connected between user terminals and remote signaling nodes for receiving and sending data messages on the established connections.  The data transceiver is responsive to a blocking status indication for imposing flow control on the data messages and marking the established connections as blocked in the memory, and is responsive to an unblocking status indication for removing the flow control and marking the established connections as unblocked in the memory.  A resource monitor compares a resource availability value with a number of thresholds, and produces the blocking status indication when it becomes lower than a start-of-blocking threshold until it becomes higher than an end-of-blocking threshold, and initiates the unblocking status indication when the resource availability value becomes greater than a start-of-unblocking threshold when at least one established connection is being blocked and continues the unblocking status indication until the availability value becomes less than an end-of-unblocking threshold or until there is no established connection which is blocked.  When the established connections are marked unblocked in the memory, the resource monitor compares the resource availability value with a new connection threshold to determine whether a new connection request is to be allowed or refused.

Title: Dimming control circuit
Inventor: CUNNINGHAM DAVID W
IPC: H02M5/257
Filed: 1992-09-14
Abstract: A dimming control circuit for a plurality of lighting fixtures includes a separate semiconductor power switch, e.g., a silicon-controlled rectifier or SCR, for providing controlled amounts of pulsed, unidirectional electrical current to each lighting fixture.  In one embodiment, a pair of SCRs, arranged in parallel, opposed relationship, are controllably pulsed to produce an alternating sequence of positive and negative electrical current pulses, of independently-controlled duration, and oppositely-conducting diodes then connect these SCRs to two separate lighting fixture. One such lighting fixture thus receives the positive current pulses, and the other such lighting fixture thus receives the negative current pulses. In an alternative embodiment, each lighting fixture receives pulsed, unidirectional current directly from a separate, independently-controlled SCR.

Patent CA-2121311-A1 (CA)
Inventor: SUYAMA KIICHI
IPC: G01N22/02
Filed: 1994-04-14
Abstract: A method of inspecting an abnormality occurring inside a pipe to be inspected and an apparatus for practicing the method, includes the steps of transmitting an electric wave having a predetermined frequency from an antenna of a transmitter located at a predetermined position inside the pipe, receiving the transmitted electric wave by an antenna of a receiver located at a predetermined position inside the pipe, and discriminating the characteristic of the received electric wave. The characteristic of the received electric wave is the intensity of the electric wave, and an attenuation amount is detected in the first example. On the other hand, the characteristic of the received electric wave is a time required to reflect the transmitted electric wave until it is received by the receiver, and a time interval between transmission of the electric wave and reception of the reflected electric wave is measured in the second example.

Title: A method for detecting a differentiation marker in normal and carcinoma cells and in biological samples and body fluid
Inventor: LOTAN REUBEN
IPC: G01N33/574
Filed: 1992-10-28
Abstract: The present invention provides a novel and improved method for the diagnosis, and continuing assessment, of squamous cell carcinoma (SCC). The protein encoded by a rabbit cDNA termed SQ10 is shown to be a molecular marker of squamous cell differentiation. By immunoblotting with antibodies raised against a 22 residue SQ10 synthetic peptide, SQ10 is shown not to be present in undifferentiated cells. SQ10 expression is up-regulated during the differentiation process and inhibited by retinoids. DNA and amino acid homologies between SQ10 and various preprorelaxin proteins allowed SQ10 to be identified as a preprorelaxin-like molecule. The SQ10 relaxin-like protein is secreted from squamous epithelial cells, and as such represents the first molecular marker of squamous cell differentiation that can be detected in body fluids. The rabbit SQ10-derived peptide was found to have a counterpart in human preprorelaxin, with the sequence MSTWSKRSLSQEDAPQTPRPV. Antibodies raised to a peptide of this sequence are also specific differentiated squamous cells. Such antibodies can be used to detect the presence of preprorelaxin-related molecules in normal and malignant squamous cells and in human biological samples and, importantly, in tissue fluids, and thus can be used in a diagnostic test for SCC.
