Land vehicle braking system

A braking system in a land vehicle having wheels for movement and a motor rotating the wheels. The braking system includes a brake rotor that is secured to one of the wheels. A brake caliper is secured to the vehicle for grasping the rotor in response to a caliper actuation signal. A brake pedal is secured to the land vehicle for movement by the vehicle driver. A pedal sensor is connected to the pedal for sensing the movement thereof and generating a braking signal in response to the movement of the pedal. A power train control module is secured to the vehicle for controlling the speed at which the motor rotates the wheels in response to a deactivation signal. A camera is mounting on the vehicle for generating a video signal representative of the incident light entering the camera. A central processing unit (CPU) is connected to the pedal sensor, the brake caliper and the camera. The CPU is adapted to receive the braking signal from the pedal sensor and, in response thereto, transmit a caliper actuation signal to the brake caliper. The CPU is also adapted to receive the video signal from the camera and process the video signal to determine whether the incident light entering camera includes light of a red color. In response to detecting light of a red color, CPU transmits a caliper actuation signal to the brake caliper and a deactivation signal to the power train control module.

Interactive neural training device

An apparatus and method for rehabilitating patients and assessing tactile skills in response to visual stimuli generated from a portable neural training device. The device generates a visual output to elicit tactile response (hand movement) from the patient. The device preferably automatically adjusts the difficulty of a session in response to demonstrated patient skill level (i.e. combination of correct responses, speed, and accuracy of responses). The invention evaluates and challenges the patient to control tactile response, overcome visual perception difficulties, or practice simple multi-tasking or reasoning skills. The invention also provides information which is valuable to those administering the rehabilitation program or assessing patient skill and / or progress. By way of example the neural training device is described with an embodiment having discrete fixed keys and an embodiment utilizing a touch sensitive display screen.

Contactless angular position sensor and method for sensing angular position of a rotatable shaft

A contactless rotary shaft position sensor provides for precision computation of shaft angle for a wide range of input shaft rotational angles. The sensor includes two annular two-pole magnets which are connected by a precision, motion-transmitting gear train. An optional second gear train between one of the magnets and the input shaft can provide additional angular rotation scaling to accurately measure either fractional or a large number of multiple turns of the input shaft. The gear ratios are selected such that one of the magnets does not rotate more than one revolution. Pairs of ratiometric Hall-effect or magnetoresistive sensors provide differential voltage signals which are used for sensing angular position of each magnet over a full 360 degrees of rotation. The single-turn magnet provides an absolute, coarse indication of input shaft rotation with a typical accuracy of 2%. The gear ratio between the magnets produces several turns of the second magnet for each turn of the single-turn magnet. Since the gear ratio between the magnets is fixed, the angle sensed for the multi-turn magnet can be predicted from the position of the single-turn magnet. This is compared to the multi-turn magnet's actual sensed rotation. The result is an improvement in accuracy directly proportional to the gear ratio between the magnets. Computation of the individual magnet rotation angles and the input shaft angle is performed using a microprocessor and appropriate signal conditioning circuits. Utilizing two magnets, input shaft rotation can be accurately measured to within 0.1% of maximum range.

Geothermal power generation

A valve arrangement (16) for a geothermal steam turbine generator (10) comprises first and second steam control valves (18, 20) for regulating the supply of steam to the steam turbine generator (10). The first and second steam control valves are arranged in parallel in a steam supply line (24) and the first steam control valve (18) has a smaller fully-open diameter than the second steam control valve (20). The first steam control valve (18) is arranged to regulate the volume flow rate of steam supplied to the steam turbine generator (10) during a speed-control phase, until the steam turbine generator (10) attains a predetermined rotational speed at which it can be connected to an ac electrical system. The second steam control valve (20) is arranged to regulate the volume flow rate of steam supplied to the steam turbine generator (10) during a load-control phase, after the end of the speed-control phase, once the steam turbine generator (10) has attained the predetermined rotational speed and is connected to the ac electrical system.
