An information terminal device (terminal) has a first radio communication unit capable of performing radio communication with low power consumption and a second radio communication unit performing data communication using a wireless LAN. In an ad-hoc mode in which data communication is performed between the terminals, as a rule, the second radio communication unit is set in a sleep mode. However, when actual data communication is necessary, an activation signal is transmitted to a terminal as a communication party by using the first radio communication unit to activate the second radio communication unit. After completion of data communication, a stop signal is transmitted to the terminal as the communication party by using the first radio communication unit to stop the second radio communication unit on the transmission side. In such a manner, transmission of a beacon signal from the second radio communication unit is suppressed, and proper power saving is realized.

A three-dimensional data generating apparatus of the present invention comprises an obtaining portion for obtaining plural image data representing images obtained by photographing an object from different viewpoints, the plural image data each representing respective one of the images; a first detector for detecting corresponding points of the images by a gradient method; a second detector for detecting corresponding points of the images by a correlation method; a selector for selecting either one of the first detector or the second detector; and a generator for generating three-dimensional image of the object based on the corresponding points detect by the selected detector. The present invention is capable of generating highly reliable three-dimensional data irrelevant to a type of an object.

A first light receiving portion and a second light receiving portion are provided on the upper surface of a moving body having driving wheels at an interval of a prescribed distance in a plane. The first light receiving portion and the second light receiving portion rotate around the axis in the vertical direction. On the other hand, a first light emitting portion and a second light emitting portion are provided on the side face of a station serving as a reference station at an interval of a prescribed distance in a plane. The first and second light receiving portions carry out sampling while rotating, so that the quantity of light reception is changed according to the directivities of the first and second light receiving portions. When the peaks of the directivities of the first and second light receiving portions match the direction of the first light emitting portion or the second light emitting portion, the quantity of light reception is maximized. Based on a rotational angle at which the quantity of light reception is maximized, the relative positions and the relative directions of the first and second light receiving portions with respect to the first and second light emitting portions are calculated.

Position detecting system

A cleaner comprises a driving unit which moves the cleaner, a cleaner unit which cleans an object to be cleaned, a sensor by which a degree of dirt on the object is detected, and a driving controller which controls the driving unit on the basis of the detected degree of dirt. The cleaner unit further comprises a controller which compares the degrees of dirt detected by the sensor before and after a cleaning operation.
