Patent CA-2236562-C (CA)
Inventor: SALAMAT BIJAN
IPC: B60T13/74
Filed: 1998-05-01
Granted: 2007-04-17
Abstract: The adaptive brake application and initial skid detection system allows rapid brake application and prevents deep initial skids. Brake pressure is compared with a predetermined threshold brake pressure. Wheel velocity error signals are also generated to indicated the difference between the wheel velocity and a reference velocity signal. A pressure bias modulator integrator responsive to brake pressure signals adjusts the wheel velocity error signals to provide an anti-skid control signal. The pressure bias modulator integrator can also be initialized to the value of the measured brake pressure when the wheel velocity error signals indicate the beginning of a skid. Brake pressure difference signals are generated to indicate the difference between brake pressure and a commanded brake pressure, and an adjusted brake pressure error signal is generated in response to the brake pressure difference signals.

Title: Spoofing detection system for a satellite positioning system
Inventor: HARTMAN RANDOLPH G
IPC: G01S1/00
Filed: 1996-06-12
Granted: 2005-01-18
Abstract: A pair of antennae (230a, 230b) in combination with a GPS signal receiver system is employed for detecting the reception of satellite information signals from a spoofing signal transmitter as opposed to those satellite information signals transmitted aboard each of the satellite vehicles which form a satellite positioning system. An indication of the pointing angle (.alpha.) or (.beta.) between the line of the antennae and the actual transmitter transmitting the satellite information signals is detected. The pointing angle and/or alternatively the range difference derived from the outputs of respective receiver systems (240a, 240b) may be observed by monitoring the behavior of the pseudo random code associated with the carrier of the satellite information signal, or the carier itself. In turn, pseudo range measurements, pseudo range rate measurements, carrier phase measurements, and/or Doppler count measurement associated with the two antennae may be used to obtain the desired discriminant, which distinguishes between genuine satellite signals, and those re-radiated via the terrestrial antenna of the spoofing signal transmitter.

Title: Position detector for fluid cylinder
Inventor: NAGAI KATSUMI
IPC: B66F9/24
Filed: 1999-08-03
Granted: 2003-10-21
Abstract: A position detector includes a fluid cylinder (20) having a piston (26). An ultrasonic transceiver (31) is provided at one end of the piston (26) outside of the moving range of the piston (26). In response to electrical signals, the ultrasonic transceiver (31) transmits ultrasonic waves to a reflection surface of the piston (26).      The transceiver (31) receives the ultrasonic waves reflected by the piston (26) and then generates electrical signals representing the reflected waves. A sensor detects that the piston (26) is at a predetermined position, at which the distance to the transceiver (31) is known. A CPU (45) supplies electrical signals to the ultrasonic transceiver (31) to produce ultrasonic waves and receives electrical signals representing the reflected waves from the ultrasonic transceiver (31). The CPU (45) then computes a piston (26) position value, which is a function of the travel time from when an ultrasonic wave is transmitted to when the reflected wave is received and the speed of the waves. The CPU (45) determines the speed of the waves when the piston (26) is detected to be at the reference position. The CPU (45) then computes the current position of the piston (26) based on the speed of the waves and on a current reading of the travel time.
