Patent GB-2238201-A (GB)
Title: Ground probing radar
Inventor: CORDES PAUL BEAUMONT
IPC: G01S13/02
Filed: 1990-10-29
Abstract: Radio transmission especially ground probing radar for locating objects buried in the ground such as pipes and cables varies the frequency of a controlled oscillator (16) by feeding it with random or pseudo-random voltages or currents. A feed for a transmitter is derived from the oscillator. Pseudo-random voltages may be produced by driving a digital to analogue convertor (14) by three outputs from a 16-stage shift register (51 ... 516). The oscillator (16) has a voltage variable capacitor (20) and its output is divided by 64 internally before being passed to a monostable (28) to drive an impulse generator (30). The transmission is received by a sampling gate (34) triggered by a voltage controlled delay 32 receiving the output from the monostable (29). The voltage controlled delay is set by a ramp voltage produced by a digital to analogue convertor (44) driven by a counter (42) receiving the output from the monostable (28). The oscillator may itself contain a noise source (126, Fig 9) connected into a feedback loop controlling the oscillator. <IMAGE>

Title: Electric braking for vehicles with two parallel electric motors
Inventor: KONRAD HARALD
IPC: B60L7/00
Filed: 1992-12-09
Abstract: A method of motor control for braking an electrically-driven vehicle with two electric motors 1, 2 connected in parallel and arranged one on each side of the vehicle and which motors are controlled by a pulse control, comprises the steps of braking the vehicle above a prescribed rpm threshold value by means of current braking, and below this value by means of regenerative braking. Instead of an rpm threshold value, the braking current or battery current can be used as the criterion for the different types of braking. An electric switching circuit using this method is described. Braking is obtained by reversing the direction switches 12 to 19, and above the rpm/current threshold value contact 4 is opened and contact 3 is closed. Current braking is obtained via thyristor 21, resistance 24, motors 1 and 2 and the field coils 6 and 7. Additionally current flows through feedback diode 20, the two motors 1 and 2 and the field coils 6 and 7. When the braking current exceed a certain value or the speed is below the rpm threshold value, such as 200 rpm, thyristor 21 is opened and the braking current flows in the opposite direction through the feedback diode 20, the motors 1 and 2, the field coils 6 and 7 and diodes 8 - 10 into the battery to provide regenerative braking. <IMAGE>

Title: Modems with timing error correction
Inventor: KAWADA NOBORU
IPC: H04L7/00
Filed: 1993-08-24
Abstract: A system (1A, 1D, 1E) modulates and demodulates a signal in a main channel for main data and a secondary channel for secondary data obtained by frequency division and uses, upon demodulation, a frequency timing extracted from the secondary channel as a sampling timing for analog to digital conversion means (1C) for the main channel. The system (1A, 1D, 1E) can rapidly restore, when a timing error occurs, a processing condition in which a normal timing is used, and comprises demodulation means (1D) which includes phase timing error detection means (6B) for detecting an error of phase timing information extracted from the main channel and storage means (7) for storing the phase timing information. When an error is detected, the demodulation means (1D) performs demodulation processing of main data using the phase timing information stored in the storage means (7). Alternatively, means (1D) performs re-leading-in processing of timing information, dependant upon carrier detection (8) or timing errors in the secondary channel (15B). <IMAGE>
