Abstract: One version of this disclosure includes a system for assigning an elevator car to respond to a call signal wherein a controller is responsible for determining which elevator car will respond to a call signal. This version includes the controller receiving a hall call signal, receiving information regarding the elevator system, determining whether the call assignment can be made in view of a first rule associated with a banned call assignment, and eliminating the rule against banned call assignments when necessary to avoid saturation of the elevator system.

Abstract: A programmable switching device that employs a Hall Effect sensor and a moving magnet is disclosed. The Hall Effect sensor is electrically connected to a programmable microprocessor that is programmed to detect changes in Hall Effect voltages at the sensor. The programmable switching device may also be configured as a rotary switching device. By using a plurality of magnets and Hall Effect transducers and orienting some magnets with their polarities in different directions, a temper-proof switch can be achieved. The programmable switching device may be connected to a serial bus that is interfaced with an elevator controller.
