Title: Transponder detection system for vehicles in toll collection lanes
Inventor: O'CONNOR ROGER J
IPC: G07B15/06
Filed: 1995-11-29
Granted: 2000-01-11
Abstract: A transponder detection system (50) for detecting the presence at a detection zone such as a vehicle toll collection lane (22) of a vehicle (100) on which a transponder (3) is mounted. Two antenna arrays (32, 34) are located on opposite sides of the detection zone (22), and have their boresights (B) directed to the detection area. For each array, a sum and difference signal of signals received from the transponder are measured. The sum channel signal is used to establish whether a transmission has occurred, and the difference channel signal is used to isolate any transponder that is at the detection zone.

Abstract: Liposome encapsulated antibiotic therapy has limited application against infectious organisms which can sequester in non-phagocytic cells. Virulence factors of these infectious organisms, for example bacterial components, when used in the formulation of liposomes can enhance the effectiveness of liposomes as delivery systems in the treatment of disease. In this manner, multi-functional liposomes can be developed to treat target diseases. In addition to serving as antibiotic delivery systems, such liposomes also have an immunization effect. Thus, the liposomes can be used for both the prevention and treatment of diseases.

Patent CA-2176459-C (CA)
Inventor: HEDBERG MATS OLOF JOAKIM
IPC: H03K19/0948
Filed: 1994-12-01
Granted: 2000-02-15
Abstract: The invention relates to a signalling system which is adapted for digital signals and which includes a signal transmitter, a signal receiver and a connection which connects the transmitter to the receiver.  The transmitter includes an output buffer which has at least one transistor connected to the lowest level of a signal supply voltage, such as "O" potential or earth potential.  Driving or steering of the transistor in response to a received control signal causes the transistor to switch from a state of high impedance to a state of low impedance which exhibits resistive or at least predominantly resistive properties, such as to form an information-carrying output signal.  A first of two series-connected transistors is connected to the lowest level of the signal supply voltage, for instance "O" or earth potential, whereas the other transistor is connected to the signal supply voltage.  A connection conductor on which the information-carrying signal is transmitted is connected between the transistors.  The transistors are brought to different states simultaneously, and in a state of low-impedance, the impedance value shall correspond to the impedance value (the resistance value) of the connection.

Granted: 2000-06-27
Abstract: A gas-fired air heating furnace has a modulatable supply air blower and a modulatable gas valve operatively connected to the combustion air heat exchanger burner.  A calibration sequence of a microprocessor-based control system is utilized to automatically determine the precise relationship between the gas valve setting and the actual heat transferred by the heat exchanger to air flowing through the furnace by measuring the actual air temperature rise across the heat exchanger obtained using initial calibration settings of the blower and gas valve.  The microprocessor uses the results of its calibration sequence to establish an adjustment correlation between the blower and gas valve settings which the microprocessor subsequently utilizes to adjust the flow rates of the blower and the gas valve in a manner maintaining a predetermined, generally constant air temperature rise across the heat exchanger while the furnace alters its overall air heating output rate in response to changing heating demands from the conditioned space served by the furnace.

Title: Silent echo generator for mobile position search in a wireless communication system
Inventor: YUN PAUL MUNSANG
IPC: G01S13/74
Filed: 1997-11-27
Granted: 2002-04-30
Abstract: Methods and apparatus for determining mobile station position in a wireless communication system are disclosed. A mobile station of the wireless system includes a silent echo generation circuit which receives a transmit time stamp transmitted in a sync channel from a base station, and processes the transmit time stamp to generate a receive time stamp. The silent echo generation circuit transmits the receive time stamp back to the base station on a spurious-like echo carrier which is offset from a data carrier of the wireless system. The base station processes the transmit and receive time stamps to compute a first ranging value, receives corresponding second and thirdranging values computed by two other system base stations which receive the echocarrier and its time stamp, and processes the first, second and third ranging values to determine a position vector indicative of the position of the mobile station. The base station then further processes the position vector to determine a bearing for the vector, and converts the result into latitude and longitude coordinates of the mobile station position. The silent echo generation circuit provides mobile position determination capability in the wireless system without significantly increasing the cost, size, weight and power consumption of the mobile station, without requiring a multilayer userinterface, and without degrading system voice quality.
