Title: Two directional multi-speed shifting gear of middle axle
Inventor: CHANG DIANLIN
IPC: B62M11/14
Filed: 1995-11-10
Abstract: A two directional multi-speed shifting gear of middle axle is made of outer ring, bearing ring, starwheel, freewheel screw cup, freewheel plate, core teeth, inner and outer pawls, and chainwheel etc.  The chainwheel is fixed on the outer ring through thread or hole.   The starwheel is geared with inner teeth of the outer ring and the core teeth. The outer pawl is mounted on pawl hub, the later is fixed on the bottom bracket case of the cycle frame.  The middle axle is passed through and fixed with the freewheel plate, the core teeth and the right crank, and then inserted into the bottom bracket case.  With such a shifting gear, a pedal cycle may be given a unique function that when the cycle is moving forward, the changing of it's moving speed in the very moving direction may be in-situ realized by variating the shifting gear through pedalling to enable the crank to be rotating in either positive or inversive directions.

Abstract: An output buffer circuit is provided, which enables to reduce the delay of a digital output signal with respect to  an  input  digital  signal.  The  output  buffer  circuit includes  first and second FETs serially connected to each other.  A gate of the  first  FET  is  applied with a  first digital input signal. A gate of the second FET is applied with a second digital input signal. The first and second FETs operate to be opposite or complementary in logic state to each other.  A digital output signal is  taken out  from a connection point of the first and second FETs. The circuit further includes a current source for causing a bias current having the same direction or polarity as that of a drain current of the first FET to flow through the first FET in the pseudo-OFF state. A turn-on speed of the first FET from the pseudo-OFF state to the ON state is enhanced by the bias current.

Inventor: GRUENENFELDER RETO
IPC: H04L49/111
Filed: 1996-08-16
Abstract: A generic cell rate monitoring algorithm (GCRA) which is implemented in an ATM network element must be tested during operation.  The method uses a second GCRA of the same kind which is synchronized with the first one, and a conformity test is carried out by comparing the results of both GCRAs.  The synchronization is preferred when both GCRAs are in a regeneration state. This is artificially produced during operation of the GCRA to be tested by temporarily changing a parameter of the agreement in such a way, that a contract violation can no longer occur. The time of reaching the regeneration state can be limited by special steps of the method.  An apparatus for carrying out the method (30) comprises a conformity decision unit (20), which counts arriving cells and compares counter positions, an implementation of the second GCRA (14) and a circuit (13) for synchronization, together with a return line (15) to an insertion circuit (16) for the cell stream in the line (1).  The cell stream is directed to both GCRA implementations (4, 14) via a branch (10).  The difference in running time from the branch to the two implementations cannot be longer than one cell transmission time.

Title: Hydraulic drive and steering systems for a vehicle
Inventor: PAUL LOWELL ALLAN
IPC: B62D12/00
Filed: 1995-05-04
Abstract: Front and rear wheeled units (13, 14) of vehicle are connected together for articulated steering.  Wheels on at least one unit are mounted for swivelling relative to the respective unit to provide kingpin steering in combination with articulation steering.  A first embodiment has front and rear kingpin steering and articulation steering performed manually and independently of each other.  In a second embodiment a steering integrator cooperates with actuators (162, 163, 212, 213, 236, 237) which control at least the articulation steering and kingpin steering of the front wheels (22, 23) to automatically integrate two types of steering so that a controlled relationship exists between an articulation angle of the front unit (13) with respect to the rear unit (14), and swivel angles of the front wheels (22, 23) with respect to the front unit (13).  A manual steering control, e.g. a steering wheel (186), controls actuation of the steering integrator.  Each wheel is powered by a hydraulic motor (32, 33, 44, 45) receiving pressurized fluid from a drive apparatus comprising a flow combiner and two flow restrictors connected in parallel with each other and communicating with outlets from the wheel motors.  Bypass valves (114, 115) can be used to bypass the flow combiner and flow restrictors as needed in certain applications not requiring the flow combiner, to reduce generation of heat in the hydraulic fluid.

Patent CA-2193435-A1 (CA)
Inventor: TARGOFF DONALD M
IPC: G01S13/88
Filed: 1996-12-19
Abstract: A center-line filter for a radar receiver (50) is a cascade of an analog filter  (54A)  and a digital filter (58A).  The purpose of the filter cascade is to filter out all but a single line of a pulsed spectrum.  The signal is passed through the analog filter, and then over-sampled by an analog-to-digital convertor (56A).  A sharp cutoff FIR filter is used as the digital filter (58A) to eliminate the remaining undesired lines.  Since the analog filter already has  the  correct  matched  filter  characteristic  in  the passband, the digital filter passband is deliberately wider and unsymmetrical.   After digital filtering, the filter output is decimated by a decimation processor  (60A)  to provide a desired output data rate.
