Abstract:
A method of selecting a light source among a plurality of light sources by means of a remote controller includes the remote controller: instructing, by omnidirectional transmission, the light sources to each transmit a directional signal comprising a code, which is unique for each light source; receiving the directional signals from the light sources; and selecting one of the light sources on basis of the received directional signals. Furthermore, the method includes: generating, remotely of the light sources, codes to be transmitted by the light sources; and the remote controller instructing each one of the light sources which one of the remotely determined codes to transmit.

Abstract:
A method of selecting and controlling devices based on wireless communication technology. The wireless controller sends a probe message to one or more devices; each device receives the probe message, obtains information in respect of its relative position with respect to the wireless controller, determines a response time to respond according to a first predefined rule, based on its relative position information: detects response signals from other devices before expiration of the response time; decides whether to send or not to send its response signal according to a second predefined rule and the detecting procedure of response signals from other devices; the wireless controller receives response signals sent by the devices after the comparison of the relative position information of each device with respect to the wireless controller, and selects the target devices from the devices. Embodiments of the present invention reduce the complexity, delay and energy consumption of the selection for wireless devices, and are especially applicable for wireless lighting systems.
Abstract:
A remote operation apparatus (300) includes: an operating-side first communication section (301) that is capable of transmitting a signal to an operation target apparatus (200); an operating-side second communication section (302) that is capable of transmitting/receiving the signal to/from the operation target apparatus (200); a connection start section (11) which transmits a connection start signal, which notifies a start of the transmission/reception of the signal via the operating-side second communication section (302), to the operation target apparatus (200) via the operating-side first communication section (301); and an operating-side communication control section (12) which transmits/receives the signal to/from the operation target apparatus (200) via the operating-side second communication section (302). With this arrangement, it is possible to easily specify a communication partner to/from which a signal is transmitted/received via the operating-side second communication section (302). Moreover, an amount of data transmitted by the operating-side first communication section (301) can be suppressed to a bare minimum. That is, it is possible to easily specify a communication partner and to suppress an amount of data transmitted by communication means for specifying the communication partner to a bare minimum.
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.
