摘要:
The present invention provides a system for generating an end of travel feedback to the driver of a vehicle where the vehicle includes a steer by wire system. The system includes a steering wheel, a steering shaft, a motor, and a brake. The steering wheel is configured to control the steer by wire system. The steering shaft is coupled to the steering wheel and rotates in conjunction with the steering wheel. To provide road feel resistance to the driver, the motor is coupled to the steering shaft. Further, the brake is coupled to a shaft of the motor and is adapted to provide mechanical resistance when the road wheel is at an end of travel position.

A steer-by-wire system for an automotive vehicle comprises a driver interface system that includes a steering wheel mounted on a steering column. A reaction torque generator is coupled to the steering column for applying a resistive torque in response to a steering command to create a steering feel. An electromechanical brake, such as a magnetorehological brake, is also coupled to the steering column. During operation, a controller receives an input signal indicative of road wheel response to a steering command and determines when the road wheels have reached a limit, such as by engaging mechanical stops mounted on the vehicle or prevented from movement by curb or other external obstacle. In response, the controller actuates the electromechanical device to prevent rotation of the steering wheel and thereby alert the driver that the road wheels have reached a limit.

An electro-optical device for processing an optical signal, comprises an electrode that is arranged and designed so that the optical signal at least partially intrudes the electrode when the optical signal is processed in the electro-optical device. An insulator is arranged adjacent to the electrode so that one face of the electrode contacts the insulator. A gate is arranged so that a voltage is applicable between the electrode and the gate such that a charge layer is induced on the face of the electrode that is contacting the insulator.

An optical control system is described which is capable of maintaining and optimizing a fiber-optic transport system within it's domain of control while interacting with other optical systems which are controlled independently. This allows the optical system to be incorporated as a building block into a larger optical network in a relatively arbitrary fashion. This provides an underlying control system for a non-linear system like optics network that is flexible and extensible.

An apparatus to separate solids from drilling slurry, having an inlet positioned over an outlet of a concentration tank to displace water that would otherwise enter the down-stream centrifuges. Baffles are provided to direct solids to the outlet and minimize the time that solids spend in the concentration tank. Fluids having solids removed therefrom are removed from the apparatus at a location remote from the outlet.

A bag handle is disclosed that includes a rigid, elongated body having an upwardly facing top surface, a downwardly facing lower surface, opposing front and back surfaces, and a pair of opposing side surfaces. A pair of hooks extend at each side surface outwardly therefrom proximate the lower surface of the body and generally parallel to each side surface. Preferably each hook extends above the top surface and terminates in a radiused point. A pair of biased locking means each comprise a biasing means, such as a coiled metal spring, and a hook engagement member, such as a glass marble. The hook engagement member protrudes from one side surface and is urged to contact one of the hooks by the biasing means. A method of use is disclosed for selectively engaging and disengaging a plurality of plastic grocery bags with the hooks and the hook engagement means.

A universal mount for acoustically coupling a musical instrument tuner to an instrument has a link connected to the tuner at one end, the link adapted and arranged to have selectable loose and fixed states, with the link including complementary first and second clamping halves joined by a compression element, and a clamp connected to the other end of the link for acoustically coupling the tuner to the musical instrument.
