Abstract
A control handle for electro-mechanical devices, such as the brakes of a train or other vehicle, is disclosed. The control handle incorporates elements for electrical switching as well as elements for measuring the angle of rotation between the control handle's rotating portion and its stationary portion. Some of the switching elements and measuring elements are combined onto a single printed circuit board in order to reduce size, complexity, and cost.
Claims21
A control handle comprising:
- a grip arranged to be grasped by a human operator;
- a shaft fastened to the grip;
- a hub fastened to the shaft and arranged to be moved rotationally by the shaft;
- a spiral resonator and switch trace board supported by the hub;
- a stationary mounting block supporting the hub for movement;
- a switch contact supported by the stationary mounting block;
- and
- a spiral track and main board supported by the stationary mounting block.

A method comprising:
- converting movement of a human operator to mechanical movement of a shaft;
- moving a hub in response to the movement of the shaft, wherein the hub is attached to the shaft and is supported by a stationary mounting block;
- moving a spiral resonator and switch trace board supported by the hub;
- determining a hub position measurement of the movement of the spiral resonator board and switch trace board in relation to a spiral track and main board where the spiral track and main board is supported by the stationary mounting block;
- activating and deactivating electrical circuits based on the interaction of the spiral resonator board and a switch contact where the switch contact is supported by the stationary mounting block;
- and
- generating as a control output based on the hub position measurement and the states of the electrical circuits.
