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 provides apparatuses and methods for controlling the brightness of a display unit based on detected movement of an external object such as a user. An apparatus includes a display, e.g., a color liquid crystal display (LCD) or organic light emitting diode (OLED). A proximity circuit generates a transmitted signal and a received signal. The received signal results from the transmitted signal being reflected by an external object. A control unit processes the received signal to determine a degree of motion of the external object. When the degree of motion is greater than a first predetermined threshold but not greater than a second predetermined threshold, the display is activated and operating at partial intensity. When the degree of motion is greater than the second predetermined threshold, the display is activated at full intensity. The degree of motion may be determined from the variation of the received signal.

Abstract: A toy vehicle includes a chassis, a right turning member that supports a right steerable road wheel and a left turning member that supports a left steerable road wheel. A rigid steering link extends across the chassis and has right and left ends that are operably connected to the right and left turning members. An actuator provides a pivoting motion on a horizontal axis extending longitudinally forward and rearward in the vehicle. The motion provided by the actuator moves the steering link side to side across the vehicle. The right and left road wheels are pivoted by the motion of the steering link. An adjustable trim mechanism includes a bias member that helps to maintain a neutral position of the steering link and a trim adjustment that modifies a position on the chassis at which the steering link and road wheels are maintained in the neutral position.

Abstract: The present invention provides apparatuses and methods for restricting access to a control unit in an environmental system based on a lock level. The control unit (e.g., a thermostat) is configured with a selected lock level, where each lock level is mapped to an associated set of features. A user is able to access any of the features from the associated set of features without entering a security sequence. Also, a feature parameter may be restricted in accordance with the activated lock level. The control unit may be reconfigured with a different lock level by an administrator only when a security sequence is entered. Also, features may be mapped by an administrator to a set of features when the control unit is operating in the locked state. When the control unit is operating in the unlocked state, all supported features can be accessed by a user.

Abstract: An electronic programmable thermostat having a program set made up of a plurality of program start times and program temperature values for a daily time period which can be automatically vacated upon initiation by the thermostat user. The user may initiate a temporary reset of the program time/temperature values whereby a microprocessor sets a new temperature value corresponding to a comfort temperature value obtained from one of the program temperature values. Preferably, the system automatically sets a temperature value equal to the highest temperature value of the program set temperatures, when in a heating mode, or the lowest temperature value when in a cooling mode. The system maintains such reset values until the beginning of one of the program start times depending upon when the reset feature was selected by the user.

Abstract: The present invention provides apparatuses and systems for adjusting a communication channel between a control unit and a remote sensor. A system may include a control unit that controls an environmental unit and a remote sensor that provides data about an environmental factor as measured at the remote sensor. The remote sensor transmits a radio frequency (RF) signal that conveys the data to control unit through a directional antenna. The RF signal is received by the control unit through an omnidirectional antenna, and a signal strength parameter is determined from the received RF signal. A signal strength indication unit provides an indication from the signal strength parameter as a user adjusts the position of the directional antenna. With embodiments of the invention, a signal strength module generates an audio signal in accordance with an audio characteristic, which is indicative of the signal strength of the received RF signal.
