Abstract: A method and apparatus for testing an HVAC component is provided, the field-testing system includes an external device to test the HVAC component, and a field testing device includes at least one testing output to provide an input signal to the HVAC component, at least one testing input to receive an output signal from the HVAC component, and an external device interface to communicate with the external device, to control the at least one testing output in response to the external device, and to monitor the at least one testing input in response to the external device.

Abstract: A thermostat includes a housing having an exterior surface and an interior surface with a view port communicating through the surfaces. A target of the thermostat is disposed outside of the housing and made of a material having a high thermal conductivity. A thermal detector housed in the housing is configured to measure a parameter indicative of at least the temperature of the target.

Abstract: A method and system for reconfiguring a thermostat for use with an HVAC system includes providing at least one output port, pre-configuring the at least one output port for a function, and reconfiguring the at least one output port for an alternate function via a processor.

Abstract: A controller, control system and method for controlling an auxiliary device comprising a wheelchair lift, ramp, or the like are provided. An exemplary embodiment of the auxiliary device controller is microprocessor-based and communicates with a vehicle's OEM controller for receiving a plurality of sensor inputs, which originate from OEM and auxiliary sensors, process the sensor inputs, and control various OEM and auxiliary systems relative to the sensor inputs to effect a number of safety interlocks. The controller may operate to coordinate various OEM and auxiliary subsystems to automate auxiliary device operation to reduce operator error.

Abstract: A vehicle access system for moving a passenger between the vehicle and ground. Some embodiments have an electrical system, a motive source coupled to the electrical system, an arm coupled to the motive source, a platform coupled to the arm, and a safety restraint system coupled to the electrical system and the platform. The vehicle access system has at least a vehicle access position and a ground access position, wherein the passenger can safely access the platform at either access position. The platform is unable to move from either access position until the safety restraint system is in place. Once operation of the access system has begun, it can continue to operate and move the passenger to one of the access positions even if the safety restraint system is subsequently removed.
