Title: Decoding of composite television signals
Inventor: CROLL MICHAEL G
IPC: H04N/
Filed: 1992-08-20
Abstract: A broadcast system is provided in which the effects of differential distortions on composite television signals are reduced. At predetermined intervals, the broadcast signal includes a test signal having high frequency components at least three average video signal levels. In a suitably equipped receiver, following demodulation by the receivers vision demodulator (20), a test signal is identified by a test signal detector (34). Measurement apparatus (24) then measures the distortion of the test signal at a number of different average video signal levels, calculates the correction required to minimise the effect of distortion at each measured signal level, and stores the corrections in a memory (28) at address locations derived from the demodulated signal by a filter circuit (32). The stored corrections are applied to an interpolator (40) which derives further corrections for other average video signal levels, the derived corrections being applied to subsequently received television signals by a controllable equaliser (38).
Patent CA-2095053-A1 (CA)
Inventor: JUDD IAN D
IPC: H04L12/56
Filed: 1993-04-28
Abstract: Described is a network addressing scheme in which a message sent from a source node to a destination node include a path address which defines the path over which the message should travel to reach the destination node. At each node between the source and destination,  the path address is compared against a predetermined value, and on determining that the address  and predetermined value  are  different,  the  node modifies the address before forwarding the message onto the next node. In a switch node having three or more ports, the identity of the output port is determined from the path address  and a portion of the  address  is deleted before sending the message out on that output port. Also described is a method of configuring a network in which one or more initiator nodes are defined,  the initiator nodes issuing query messages to an adjacent node which responds by sending the initiator details of the number of operational ports which are implemented in the adjacent node. The initiator node then issues query messages addressed to those nodes which are attached to the operational ports on the adjacent node. This continues until the initiator has walked through the entire network at which point the configuration process is complete.

IPC: H04Q3/00
Filed: 1994-09-06
Abstract: Apparatus for providing displays in which the locations of nodes of a graph relative to each other are a function of the significance of a relationship between the nodes. The technique used to locate the nodes produces groups of nodes with significantrelationships to each other which are set visually apart from the other nodes. The relationships between the nodes are defined by using a statistic to give weights to links between the nodes. Statistics may also he used to determine the size, shape, and color of the nodes and the color and width of the links. The display may also include histograms which show the numbers of links or nodes which have given values of the statistics and which relate the colors in which the nodes and links are displayed to values of the statistics. The histograms may further he used to interactively define masks for links and nodes, and masked links and nodes are not taken into account in making the display.

Abstract: METHODS AND COMPOSITIONS FOR THE ORAL DELIVERY OF               THERAPEUTIC AGENTS  Abstract of the Disclosure Alginate beads are employed as a site specific oral delivery system for cationictherapeutic agents, such as TGF-.beta.1, designed to target the agents to the luminal side of the small intestine. Improved delivery of bioactive material is obtained by: 1) incorporating selected polyanions in the alginate beads to shield the cationic therapeutic agent from interaction with alginate and/or 2) acid treating alginate beads containing the therapeutic agents to reduce the molecular weight of alginate and its interaction with the agents. Enhanced bioactivity of therapeutic agents released from the alginate is attributed to the ability of polyacrylic acid to shield the agents from interaction with lower molecular fragments of acid treated alginate.

Title: Acoustic beam levitation
Inventor: GUIGNE JACQUES Y
IPC: F16C32/00
Filed: 1994-11-10
Abstract: A system is described that uses acoustic energy to position an object, which simplifies the application of forces in defined directions to the object and which enables the application of large forces to the object. The system includes transducers (21-24, FIG. 1) that direct separate acoustic beams (31-34) at the object (12), with the system constructed so the beams do not create standing wave patterns. A plurality of beams whose phases at the object are not closely controlled, are directed at different surface areas of the object so the beams do not substantially overlap at the object and create possible canceling effects. A very large force is applied to the bottom (124, FIG. 8) of an object lying in a gravity environment, by directing a plurality of beams (141-145) at the same area at the bottom of the object, and with the beams being controlled so they are substantially in phase at the object area. This plurality of beams can also replace one or all of the transducers (21-24, FIG. 1) to provide much stronger forces to position and manipulate the object. The wavelength (B, FIG. 2) of the acoustic energy in each beam is preferably much less than one-tenth the diameter (C) of the object in order to obtain efficient momentum transfer of energy to the object.

Patent CA-2143768-A1 (CA)
Inventor: DEAN ARTHUR L
IPC: H02P25/06
Filed: 1995-03-02
Abstract: This invention pertains to sensorless measurement of electromagnetically induced displacement in actuators and similar units. Primarily, the device imposes a constant frequency and amplitude excitation sine wave on a coil through a fixed impedance of a drive isolation network.      The amplitude and phase of the voltage across the coil fluctuate depending upon the coil's inductance. This variation in the value of the inductance is dependent upon the change in magnetic flux density generated by the coil current and the displacement in air gap between the coil pole and armature. Accordingly, a measurable magnitude of displacement can be controllably imposed upon a system of solenoids. The displacement is thus measured and set without the use of extrinsic sensors.
