  • Publication number: 20080266846
    Abstract: The present invention supports a solar lamp that includes a solar panel that charges a battery to power a display panel and a processor. Based on environmental factors measured by a sensor, the processor instructs the display panel to change colors based on the value of an environmental factor. If the measured environmental factor changes values, the processor may subsequently instruct the display panel to change colors. The solar lamp may be controlled by a remote controller. The solar lamp has a receiver circuit that receives control data from the remote controller to configure the display panel. Based on the control data, a processor may instruct the display panel to change colors or change intensity. The remote controller controls a solar lamp through a wireless communications channel. Based on an indication, a processor sends control data through a wireless transmitter circuit to configure the display panel of the solar lamp.

  • Publication number: 20080265804
    Abstract: The present invention provides apparatuses, computer media, and methods for controlling the speed and direction of a controlled device. An input device provides input information, which is converted into speed information and direction information. A controlled device, e.g., a variable speed motor, is then instructed to operate at a device speed and direction in accordance with the speed information and direction information. The remote device may include a circular input device through which a user draws strokes. The remote device instructs the controlled device to operate at a device speed and a direction in accordance with extracted characteristics of the entered stroke such as the speed of drawing the stroke and the direction of the stroke. The remote device then transmits a signal with speed and direction information to control the controlled device.

  • Publication number: 20080244730
    Abstract: The present invention provides apparatuses and methods for providing security for a secured unit with a security code. The secured unit may be locked to prevent an unauthorized user from accessing the secured unit. In order to unlock the secured unit, a user enters a sequence of strokes through an input device, e.g., a circular input device. A security module extracts stroke information from the entered strokes and unlocks the secured unit when the extracted stroke information matches the security code. Stroke information may be indicative of the locations of the start and end points and the direction of each stroke. A security code is configured for a secured unit by a user entering a sequence of strokes through an input device. The security code is determined from stroke information. The stroke information may be verified by the user re-entering the sequence of strokes.

  • Publication number: 20080228432
    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.

  • Patent number: 7400942
    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.

  • Publication number: 20080001595
    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.

  • Publication number: 20080000246
    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.

  • Publication number: 20070085696
    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.
