Abstract: Remote control systems that can distinguish predetermined light sources from stray light sources, e.g., environmental light sources and/or reflections are provided. The predetermined light sources can be disposed in asymmetric substantially linear or two-dimensional patterns. The predetermined light sources also can output waveforms modulated in accordance with one or more signature modulation characteristics. The predetermined light sources also can output light at different signature wavelengths.

Abstract: A wireless battery-powered daylight sensor for measuring a total light intensity in a space is operable to transmit wireless signals using a variable transmission rate that is dependent upon the total light intensity in the space. The sensor comprises a photosensitive circuit, a wireless transmitter for transmitting the wireless signals, a controller coupled to the photosensitive circuit and the wireless transmitter, and a battery for powering the photosensitive circuit, the wireless transmitter, and the controller. The photosensitive circuit is operable to generate a light intensity control signal in response to the total light intensity in the space. The controller transmits the wireless signals in response to the light intensity control signal using the variable transmission rate that is dependent upon the total light intensity in the space. The variable transmission rate may be dependent upon an amount of change of the total light intensity in the space. In addition, the variable transmission rate may be further dependent upon a rate of change of the total light intensity in the space.

Abstract: A monitor-light-emitting device and multiple light-emitting devices are mounted on a board, and a light-guiding member is disposed in front of these devices. Monitor light emitted from the monitor-light-emitting device is directly supplied to a light receiving device. Part of light emitted from the multiple light-emitting devices is incident on the light-guiding member and is used as reference light. The reference light is received by the light receiving device. Reflected detection light that has been reflected off a target object located in front of the optical sensor is transmitted through the light-guiding member and is received by the light receiving device. A condenser is disposed in front of the light receiving device and the reference light or the reflected detection light is efficiently supplied to the light receiving device.

Abstract: An illumination system and method is disclosed. In one example, the illumination system comprises a light source, a controller controlling the power output of the light source, and a light sensor wirelessly communicating with the controller. In a normal mode, the controller controls the light source such that the light level remains substantially constant. In a change mode, the controller controls the light source such that the light level is gradually changed with a predetermined change rate so as to decrease a deviation from a target level, The controller switches from the normal mode to the change mode on the basis of input signals received from the light sensor. The light sensor measures a light level, and decides whether or not to communicate a signal to the controller. The light sensor refrains from transmitting a signal when receiving the signal does not cause the controller to change its control behaviour.
