Abstract:
In a remote control system, when a user directs a host device of a portable type toward target devices for search and specification, a search signal including a unique identifier (UID) is transmitted from a directional antenna. Each of the target devices stores the UID included in the received search signal in a memory unit, and transmits a response signal including device information on itself from an antenna. The host device identifies one of the target devices based on the device information included in the response signal, runs a control program for the identified target device, and displays an operation screen on a display unit. When the user instructs the remote operation on the operation screen, the host device transmits a remote control signal including the UID from the omni-directional antenna. When the target device receives the remote control signal including the UID that matches with the UID stored in the memory unit, the target device controls a function unit according to the remote control signal.
Abstract:
The field of view of a video camera is set to include electric appliances such as a refrigerator, TV set, air conditioner and lamp installed within a room. When the user operates a remote controller to emit a visible laser beam toward a controlable range including these electric appliances set within this field of view, and designate a certain one of the appliances by the resulting pointer within the controlable range, the video camera for extracting only the visible laser beam of a wave length picks up this pointer, and a control box detects the position of the pointer within the controlable range from the output of the camera so that the appliance designated by this pointer can be detected and remotely controlled by use of the remote controller.
Abstract:
A system for communication with addressable electronically-controllable appliances using a generalized pointing device is provided. The system includes a pointing device that can communicate with dissimilar types of target appliances from a position remote from those appliances and an appliance interface that makes the target appliances compatible with the pointing device. Use of the system is believed to allow the convenience associated with use of a computer's graphical user interface (GUI) to be realized in communication with physical objects, i.e. the target appliances. In an embodiment for one-way communication from a pointing device to a target appliance, the pointing device may comprise an actuator, an input-output interface, and a transmitter. In an embodiment configured for two-way communication between the pointing device and an appliance, the pointing device may further include a receiver. The appliance interface may include a receiver, an input/output interface, and a driver to convert received pointer command signals to corresponding functions of the appliance. In an embodiment configured for two-way communication, the appliance interface may further include a transmitter. The system may be configured for transmission using optical signals, radio-frequency signals, or both.
Abstract:
A remote control device, which controls any of a plurality of apparatuses by transmitting a remote control signal for controlling a target apparatus in response to a user operation, detects a position of the remote control device and generates self-position information indicating the position, and specifies one of the apparatuses that is the closest in distance from the remote control device, as the target apparatus, based on the generated self-position information and a predetermined criterion. When the remote control device detects a user operation, the remote control device transmits a remote control signal corresponding to the detected user operation.
Abstract:
A plurality of spaced ceiling mounted fixtures or other controllable electrical appliances have radiation detectors mounted within each fixture and wired internally of the fixture to a dimming circuit or to a ballast. The radiation detectors have sensitivity over a wide angle and have elongated plastic radiation conduction rods which extend to or beyond the plane of the lens of the fixture to be located free of shadow effects of reflections of the fixture lens. A flexible end light fiber optics can be used in place of the acrylic rods. A narrow beam radiation transmitter selectively illuminates one of the rods or end light fiber optics without illuminating the others. The dimming circuits or ballasts within the fixtures can be further controlled by external dimmers, occupancy sensors, timeclocks, photosensors and other types of input devices. The radiation detector and ballast can occupy a common housing and share the same power supply and circuit board. The microcontroller for the radiation detector operates with a 4 of 4 voting mode until a valid signal is detected to switch the system to a 3 of 4 voting mode. A novel mounting adaptor for mounting a visible light fiber optic cable is disclosed with the visible light fiber optic cable conducting infrared radiation for up to 24 inches.
Abstract:
A motorized window covering includes an actuator that is controlled by a remote control unit. The remote control unit emits a blinking visible light beam and an invisible encoded light beam superimposed thereon. The blinking visible light beam allows a user to accurately direct the encoded light beam, which carries the control data, toward the actuator. Consequently, the user can control individual actuators within an array of actuators.
Abstract:
A remote operator includes a laser-actuated photo switch. A hand held laser sweeps past an active or sensitive area on the unit to cause the unit to change states, e.g., between “on” and “off.” In a lamp dimmer implementation, pointing the laser at the unit can cause it to increment (between dim and bright, fast and slow, soft and loud, etc.). The laser produces a narrow beam of laser light at a single characteristic wavelength. A dark filter or other optical filter can be disposed over the optical sensor element for passing only light at the laser's characteristic wavelength. A monostable, bistable or other multivibrator unit can be employed to effect toggling or a timed on (or timed off) operation. The remote operator can be integrated into the housing or body of the load device, e.g., into a ceiling fan, wall switch, table lamp, or any other device in need of remote controlled operation.

Abstract:
A method for communication with addressable, electronically-controllable appliances using a generalized pointing device is presented. The pointing device can communicate with dissimilar types of target appliance, and each appliance is associated with an appliance interface that makes the target appliance compatible with the pointing device. Use of the method is believed to allow the convenience associated with the use of a computer's graphical user interface to be realized in communication with physical objects, i.e. the target appliances. The method includes orienting the pointing device for reception of its pointer command signals by an appliance interface of the targeted appliance, transmitting a selection signal from the pointing device to the appliance interface, and transmitting a pointer command signal to the appliance interface. In an embodiment involving two-way communication between the pointing device and appliance interface, the method further includes observing appliance response information transmitted from the appliance interface to the pointing device. The method may include establishment of a line-of-sight transmission path between the pointing device and appliance interface for optical signal transmission. Additionally or alternatively, the method may include use of a non-line-of-sight transmission path for radio frequency signal transmission.
