Abstract: A power supply system of a transport system includes: a direct-current intermediate circuit; a motor bridge connected to the direct-current intermediate circuit, for supplying power between the direct-current intermediate circuit and the motor that moves the transport appliance; and also an energy storage and a direct-current converter based on indirect power transmission connected between the energy storage and the direct-current intermediate circuit, for controlling the power supply between the energy storage and the direct-current intermediate circuit. The direct-current converter based on indirect power transmission includes: a controllable solid-state switch, for disconnecting the power supply occurring from the energy storage.

Abstract: A motion control device for controlling a motor is presented. The motion control device is operable to scale or adjust an input relative to an input range that is based on calibration values and to use that scaled input to produce a drive signal to drive the motor. The motion control device performs a self-calibration to produce the calibration values. The self-calibration involves measuring home position and full travel position values for the motor.

Abstract: A device for steering a vehicle, particularly a helicopter or even a simulator, comprising a handgrip that can be moved in a manner that is linear to the drive of a drive device, particularly the power unit or motor. The linear motion of the handgrip is coupled with a rotational motion of a drive element.

Abstract: A digitally controlled hybrid power module is controlled by a programmable controller. The hybrid power module includes a digitally controlled switching supply with an output coupled to an input of a digitally controlled linear voltage regulator. Independent control of switching supply and the linear regulator is provided by the programmable controller, which may be a field programmable gate array (FPGA), microcontroller, or digital signal processor (DSP). The programmable controller may independently control one or more power modules. Each power module may also include enable switching and an associated current clamp for capacitive loads. An output voltage transient suppressor may also be used to control transients, such as those produced under fast switching conditions.

Abstract: The present invention provides a sensor for an adjustable system of a vehicle. The sensor is utilized to facilitate monitoring of adjustment positions with respect to a reference in the system. The sensor comprises a mechanical interface that allows for the input of movement and an electrical device coupled to the mechanical interface that is capable of changing an electrical signal in relation to the movement of the mechanical interface. The electrical signal, which is proportional to the movement input to the mechanical interface, is utilized by a control unit for control purposes, such as to control the positioning of vehicle control pedals, control the positioning of an adjustable seat of a vehicle, or to control the temperature adjustment in a vehicle HVAC system.

Abstract: A powered movable chair controllable by a user. The chair includes a frame, a powered apparatus mounted to the frame to power the movable chair, and a controller including a control circuit coupled to the powered apparatus. The control circuit includes at least two switches for selectively controlling a change of the status of the powered apparatus between a locked state and an unlocked state. The control circuit is operable to generate an output signal allowing control of the powered apparatus in the unlocked state and preventing control of the powered apparatus in the locked state. The control circuit is further operable to change from the unlocked state to the locked state when a user operates a first switch of the at least two switches, and to change from the locked state to the unlocked state when a user operates a second switches of the at least two switches for a predefined time period.
