High Energy Density Elastic Accumulator and Method of Use Thereof

The invention is an accumulator which stores energy by deforming from its original shape in response to the flow of a pressurized fluid. The stored energy is returned when the fluid flow is reversed and the accumulator returns to its original shape. At least one part of the novelty of the accumulator is that it captures elastic strain energy of a stretched bladder, as opposed to relying on gases and metals for energy storage as is usually seen in conventional accumulators.

A surgical instrument can be disinfected or sterilized, and has a rechargeable secondary battery incorporated therein. A distal treatment section of the surgical instrument is ultrasonically oscillated or otherwise activated using the secondary battery as a driving power source to perform surgery on a living tissue.

ANTI-BLOCKING CONTROL SYSTEM

CIRCUIT ARRANGEMENT FOR A BRAKE SYSTEM WITH ELECTRONIC BLOCKING PROTECTION CONTROL

A circuit arrangement for a vehicle with electronic anti-lock regulation has circuits for the individual regulation of the braking pressure cycle in the wheel brakes on a vehicle axle and to limit the yawing moment resulting from differences in braking pressure. In addition there are circuits (6) which detect the pressure reduction signals (PA1, PA2) individually and determine the pressure difference DA12) therefrom. With different frictional values ( mu -split), the average pressure release gradient on the high-pressure wheel is varied dependently upon the pressure difference (DA12) and the vehicle deceleration. At the moment when the "yawing moment peak" occurs, i.e. immediately before the low-pressure wheel returns to the stable region, the braking pressure at the high wheel is reduced by a value depending on the vehicle deceleration and the pressure difference.

ABS variant nominal hold pressure

A brake control system is described that maximizes the braking efficiency of an under-damped actuator, such as a motor-driven linear screw. When an incipient lock condition is detected, the system determines the optimal brake pressure, relieves brake pressure and measures the duration of the pressure release. When the wheel is approaching recovery, but has not yet substantially recovered, the system holds brake pressure constant at a value calculated to represent the amount of pressure remaining at the wheel brake. This calculated hold value is based upon the measured optimal pressure and the measured release duration, and allows the wheel to continue to reaccelerate towards recovery while preventing unnecessary pressure relief. Once the wheel recovers, the system reapplies brake pressure to a substantial fraction of the optimal pressure without over-exciting the actuator and over-shooting the desired pressure.

Braking systems

Process for improving the control behavior of an anti-lock control system

In order to improve the regulating behaviour of an antilock or skid control system, in particular to improve the steerability of a vehicle and the drive stability when braking in a curve, criteria for recognising curves and their orientation are derived from the skidding of the individual wheels of the vehicle. When a curve is recognised, the normal regulation mode for straight driving is changed into a regulation mode for curve driving. The normal regulation mode for straight driving is characterised by an individual regulation of all wheels or by an individual regulation of the front wheels combined with a select-low regulation of the rear wheels. In the regulation mode for curve driving, the mean pressure level of the front wheel at the inner side of the curve is lowered by a predetermined value and the mean pressure level of the front wheel at the outer side the curve is increased by a predetermined value. The mean pressure level of the rear wheels may also be modified in a corresponding manner in vehicles provided with select-low regulation and pairs of valves for each wheel.

Brake control system for an electrically operated vehicle

In an electrically operated vehicle in which a regenerative braking operation is performed to apply a regenerative braking torque to a wheel, if the regenerative braking torque reaches its maximum value and is insufficient to brake the wheel, a static hydraulic pressure outputted from a master cylinder is supplied to the wheel brake cylinder mounted on the wheel until the brake pedal reaches a retained position. Thereafter, a dynamic hydraulic pressure is supplied to the wheel brake cylinder. While the brake pedal is in movement from the rest position to the retained position, the wheel brake cylinder is supplied with only the static hydraulic pressure and while the brake pedal is being retained at the retained position the wheel brake cylinder is supplied with the static hydraulic pressure and the dynamic hydraulic pressure.
