Abstract:
A load control system for a building having a heating and cooling system and a window located in a space of the building uses a daylighting procedure to adjust the amount of power delivered to the lighting load in response to the amount of daylight entering the window, and controls amount of daylight entering the window in order to attempt to reduce the power consumption of the heating and cooling system if the daylighting procedure is not causing the heating and cooling system to save energy. If the lighting load is consuming more energy when the fabric of the motorized window treatment is at a position above the fully-closed position than the lighting load would consume if the fabric was at the fully-closed position, the motorized window treatment moves the fabric to the fully-closed position.
Abstract:
A remote control for a wireless load control system comprises a housing having a length and a width slightly smaller than the length and the width of an opening of a standard faceplate, respectively, such that the housing is adapted to be received within the opening of the standard faceplate. The remote control comprises a controller, a radio-frequency transmitter coupled to the controller, and a battery coupled to provide power to the controller and the radio-frequency transmitter, which are all contained within the housing. The remote control may be provided with multiple mounting means. For example, the remote control may be coupled to a lanyard, clipped to a car visor, rested on a table top, or mounted to a wall.
Abstract:
Directional indicators on the control buttons of an electrical control for a light dimmer or a motor controller are formed by triangular lines with vertices pointing away from one another and in a direction related to the change initiated by pressing the related button. The indicia are formed by narrow lines of length less than about one hundred thousands of an inch, and tend to disappear from view as an observer is farther away from the control buttons. The buttons are formed of right triangles with adjacent spaced hypotenuses and fit into a rectangular area. On/off rectangular buttons of the same color as the control buttons are atop and below the rectangular area.
Abstract:
A wall-mountable electrical timer for controlling the delivery of power from an AC power source to an electrical load, such as a lamp or a fan motor, includes: a timer adjustment actuator for selecting a predetermined time period of operation for the load; a toggle actuator for starting the timer, turning off the timer, and placing the timer in a bypass mode of operation; a vertical linear array of light-emitting diode visual indicators for indicating the length of a predetermined time period, the time remaining, and whether the timer is in the bypass mode; a controllably conductive device for regulating the delivery of power from the AC source to the load; and a controller for receiving inputs from the timer adjustment actuator and the toggle actuator, and for transmitting outputs to the visual indicators and the controllably conductive device.
Abstract:
A system for labeling a button in the field includes a label defining a peripheral boundary and a label-receiving surface defined by the button and adapted for receipt of the label. The label-receiving surface of the button defines a perimeter adapted to accommodate the peripheral boundary of the label. The button includes side and end portions defining raised edges or lips that define the label-receiving surface. The side and end portions serve to align the placement of the label. The side and end portions also protect the edges of the label against accidental dislodgement and peeling. The label typically has a suitable button identifier such as text, or a graphical design element such as an icon, printed thereon.
Abstract:
An infrared hand-held remote control for handling a single or plural devices such as lights, shades, drapes and the like contains ergonomically selected and placed control buttons that are self-describing and easy to use. It allows explicit, easy-to-use control of different functions by providing for each function to be controlled vertically disposed discrete buttons that provide "all or nothing" control of some physical feature and similar, vertically disposed and horizontally aligned "adjust" buttons that allow for fine and continuous control of the physical quantities between the extremes or limits of the discrete button functions. Successive groups of buttons provide for the control of different appliances or devices, where each group of buttons is identified by easy to comprehend icon or alphabetic representations.
