Abstract: A control circuit selectively energizes a load, such as an elevator or escalator brake (12). The circuit includes a transformer (28) with a primary-winding connected to a series with a semiconductor switch (40) that is driven by a pulse width modulation (PWM) controller. Power to the PWM controller is supplied through safety relay contacts (52A, 52B). When the load is to be energized, the safety relay contacts are closed and the PWM controller drives the semiconductor switch to supply energy through the transformer to the secondary circuit. A command signal to secondary circuitry (64) causes power in the secondary to be applied to the load (12). If the safety relay contacts open, the PWM controller turns off and power is no longer delivered to the secondary circuit and the load.

Abstract: A wheel brake for an aircraft, the brake comprising a support (2) that receives at least one electromechanical actuator (1) fitted with a pusher (8) facing friction elements (3) and movable under drive from an electric motor (6) to apply a braking force selectively against the friction elements. The actuator is non-reversible such that a reaction force applied on the pusher cannot cause the electric motor to turn, and the actuator is associated with elements (30, 31, 32, 33, 34) for selectively switching off an electric power supply to the electric motor, which elements allow power to be delivered to the actuator in normal circumstances, and switch off the power if (a) the measured speed of rotation (wmes) of the electric motor drops below a first predetermined threshold (S1); and (b) the commanded speed of rotation ( ω) of the electric motor drops below a second predetermined threshold (S2).

Abstract: In an antiskid control system for a motor vehicle, the speed and acceleration of at least one vehicle wheel are detected, and from the detected wheel speed, the speed of the vehicle is estimated. First and second variable threshold values are derived from the vehicle speed. The wheel speed and acceleration are compared with the first and second thresholds, respectively, to estimate the level of road surface friction and to operate solenoid-operated hydraulic brake pressure decreasing means. The operating period of the pressure decreasing means is controlled in accordance with the estimated road surface friction to prevent excessive reduction of the brake pressure and premature locking of the wheels.

Abstract: An actual slip ratio of a wheel is estimated from a slip ratio speed of a wheel calculated according to a running state of a vehicle based on relationship between a slip ratio of the wheel of the vehicle and the slip ratio speed of the wheel set in advance. Typically, the actual slip ratio is estimated supposing that the slip ratio of the wheel calculated according to the running state of the vehicle, when a change rate of the slip ratio speed becomes larger than a predetermined value set in advance, is a reference slip ratio determined in advance according to the relationship between the slip ratio and the slip ratio speed set in advance. Therefore, it is possible to improve control accuracy when controlling a state of the vehicle by decreasing an effect of operation by a driver and a road surface, for example.
