Abstract: The present invention provides methods and apparatuses for configuring an electrical device to a selected orientation. Direction information that is indicative of the orientation of the electrical device is provided by a directional detection switch. A processor selects a selected orientation from a plurality of permitted orientations by processing the direction information and instructs a display unit to operate in the selected orientation. Different adjacent contacts of a directional detection switch are activated corresponding to different orientation of the electrical device. A conductive ball may be positioned by gravity and consequently conducts an electrical current between two corresponding adjacent contacts based on the orientation of the electrical device. A display unit of an electrical device may include an output component or an input component that is configured based on the orientation of the electrical device.

Abstract: The present invention controls a room temperature by controlling an environmental control unit. A total span about a setpoint temperature is adjusted in accordance with a previous total span and a multiplicative factor. The multiplicative factor is periodically updated from a desired cycle time and a previous cycle time. The room temperature may also be controlled by adjusting a duty cycle for controlling an environmental control unit. The duty cycle is adjusted based on an error associated with a previous control cycle and an attenuation factor. A new control cycle may be started by cutting the previous control cycle or a current control cycle may be extended if a predetermined condition is detected. The control mode is selected based on environmental characteristics and room characteristics. The control mode may include a span control mode and a duty cycle control mode that is selected from the cycle rate.

Abstract: Aspects of the invention provide apparatuses, methods, and systems that support measuring and conveying energy consumption by an electrical device. An apparatus includes an energy sensor that measures an incremental energy value consumed by an electrical device. Apparatus obtains the incremental energy value, accumulates an energy usage measurement in accordance with the incremental energy value, provides requested information about energy consumption of the electrical device in response to a request from a network controller, and adjusts the energy usage measurement in accordance with the requested information. The total energy consumption may be partitioned into at least one energy component, in which the at least one energy component corresponds to the energy consumption of the electrical device during an associated time interval. A network controller may use the energy consumption information to determine a new set temperature for a thermostat unit that instructs the device control logic.

Abstract: The present invention provides methods and apparatuses that support the transfer of data from a thermostat unit to a controller unit to control a variable speed heating, ventilation, and air conditioning (HVAC) system. The duty cycle of a signal (that is sent from a thermostat unit to a controller unit) is adjusted in accordance with a temperature difference between the ambient temperature of an environmentally controlled space and a set temperature. The controller unit measures the duty cycle to determine the temperature difference and adjusts the speed of a blower motor or compressor in accordance with the temperature difference. The signal is switched on and off, in which the AC waveform is conducted and blocked by the thermostat unit and received by the controller unit. The controller unit measures the duty cycle of the received signal, determines the temperature from the duty cycle, and adjusts the speed from a predetermined relationship.

Abstract: The present invention supports pairing a transmitter and a receiver that use the same power line and power module. The transmitter associates an identification number with a command message so that a receiver can ascertain that a command message is intended for the receiver. The transmitter uses the time from the power up to the first zero crossing of the AC signal to generate a matching seed for both transmitter and receiver. The transmitter generates an identification number by incrementing a counter each incremental time interval between power up and the occurrence of the first zero crossing of the AC signal and sends the generated identification number to the paired receiver after power up but before a predetermined time interval. The receiver stores the generated identification number and compares the stored identification number with a received identification number that is received in a subsequent command message.
