The present invention is an improvement to previously known systems for controller area networks and the method of communicating across such networks. The system and method introduces interpolated time markers to provide higher resolution bit container, for communicating data bits across the data bus of a three-wire controller area network. The interpolated time markers allow devices on a controller area network to effectively double tie amount of bandwidth available for communication and can in some cases even further increase the bandwidth beyond a factor of two.

An apparatus for checking conditioning mode of a heat pump system includes: (a) a temperature sensing device coupled with the heat pump system at a sensing locus; (b) a comparing device coupled with the temperature sensing device and configured for comparing a first temperature sensed by the temperature sensing device at a first time with a second temperature sensed by the temperature sensing device at a second time to determine an extant conditioning mode; the extant conditioning mode being a first conditioning mode when the second temperature is greater than the first temperature; the extant conditioning mode being a second conditioning mode when the second temperature is less than the first temperature.

The disclosure includes an HVAC data processing and communication network and a method of manufacturing the same. In one embodiment the network includes a duct, a blower and a controller. The blower is configured to receive a control message from a data bus. The duct is configured to direct air flow from the blower. The controller is configured to publish the control message to the data bus. The controller thereby commands the blower to provide air to the duct at an initial volume rate and to increase the volume rate until the controller detects onset of a cutback mode of the blower.

Activation and deactivation of a plurality of heating elements in an electric heating system are separately controllable in accordance with the present invention. Individual heating elements are sequentially activated in response to a demand for heat. A predetermined time delay is imposed between successive activations of the heating elements to allow time to satisfy the demand for heat before another heating element is activated. Normally, the heating elements are also deactivated sequentially in response to a reduced demand for heat, with a predetermined time delay between successive deactivations to allow time to respond to the reduced demand for heat before another heating element is deactivated. A temperature sensor is located in the air discharge plenum of the heating system for sensing the temperature of the discharge air. The discharge air temperature is used to control the operation of the heating elements, a two-speed heat pump, and the "off cycle" of the heating system blower.

Automatic food frying and dispensing apparatus is disclosed which is housed in a supporting cabinet and includes a device for holding a supply of cooking oil and a heating device for maintaining the temperature of the cooking oil at a predetermined temperature. A fan assembly exhausts air through the top of the cabinet. A derated precipitator, a flame arrester and a charcoal filter are positioned upstream of the fan assembly and in the path of air flow. A switch device is positioned in the path of air flow and shuts off the heating device if the air flow drops below a predetermined value. Food handling apparatus automatically lowers the food to be cooked into the cooking oil when a customer selects a desired cooking time and automatically raises the food from the cooking oil and dumps the food into a container positioned at the food collection station at the end of the preselected cooking time.

An improved timed-off control apparatus and method are provided to prevent excessive cycling of an electrically operated device, such as an air conditioning compressor. The timed-off control apparatus provides a predetermined timed-off period (e. g. , five minutes), during which the electrically operated device is constrained to remain in an off state after the device is deactivated by a loss of power. For example, in an air conditioning system, fluctuations in power supply voltage and thermostat switch bounces may result in excessive cycling of the system compressor. By constraining the compressor to remain deactivated for the selected timed-off period, the compressor is protected against excessive cycling. In order to achieve consistent and predictable timed-off periods, a field effect transistor (FET) is used in conjunction with a resistance/capacitance (RC) circuit. When the power supply is interrupted, the FET is turned off state and remains off during the timed-off period.
