An HVAC system is disclosed. In some embodiments, the HVAC system comprises a first component comprising a first communication module; a second component comprising a second communication module, the second component configured to communicate with the first component. The second communication module is configured to receive a first set of information over a power line and a second set of information over a communication line.

Methods and systems for data communications in HVAC systems

Provided are embodiments for a heating, ventilation, and air conditioning (HVAC) system for providing sensor information and sensor communication over relay-controlled power line. The system can include a controller of the HVAC system and a first power line converter coupled to the controller. The first power line converter is configured to receive data over a serial bus, convert the data into a communication message for transmission onto a power line, wherein the power line is configured to transmit power and communication messages, and transmit the communication message over the power line. Also provided are embodiments for transmitting and receiving a communication message over relay-controlled power line.

HVAC sensor information and sensor communication over relay-controlled power line

A zone board for a heating, ventilation, and air-conditioning (HVAC) system including: a controller connector configured to electrically connect a controller to the zone board, the controller being configured to control operation of the HVAC system; a unit connector configured to electrically connect an indoor air handler to the zone board; and a thermostat connector configured to electrically connect a thermostat in a first zone to the zone board, wherein the thermostat connector is a 24-volt printed circuit board connector.

Variable speed airflow zone board

The present invention provides a system and method for degrading and disabling a vehicle's engine throttle. The vehicle disable system includes a throttle position sensor that generates a throttle position signal, an electronic control module ('ECM') input connected to the ECM on which the throttle position sensor provides the throttle position signal to the ECM, and an override input that enables an idling signal to be transmitted to the ECM instead of the throttle position signal. The method of the present invention includes the steps of receiving an input signal related to the state of the driver input mechanism, interpreting the input signal, and at least one of degrading and disabling the throttle based on the interpretation of the input signal.

Throttle disable method and system

A technique for providing management of a motor vehicle information system includes a number of steps. Initially, a wake-up message is received from a portable transmitter. In general, the wake-up message, unique to the portable transmitter, is provided responsive to user activation of a button that is electrically coupled to the portable transmitter. Next, it is determined whether power capability of the motor vehicle is adequate responsive to receipt of the wake-up message. When the motor vehicle power capability is adequate, power is provided to a wireless interface, a vehicle information system and a mass storage device, all of which are located within the motor vehicle. Information is then received via the wireless interface and stored in the mass storage device, when the power capability of the motor vehicle is adequate.

Technique for providing management of a motor vehicle information system

A vehicle disable system including an onboard computer linked to a throttle control relay. The onboard computer is capable of communicating to a remote control center by way of telecommunications link. If certain security protocols are breached, the control center communicates a shutdown command to the vehicle by way of the telecommunications link and the vehicle initiates a shutdown procedure for incapacitating the vehicle throttle controls.
