摘要:
A movement control system useful for an apparatus comprising a movable member movable between two positions, a motor and a sensor device for producing an output value which changes during the movement of the movable member. The control system drives the motor in a first amount so as to move the movable member from one of the two positions to the other position and thereafter drives the motor in a second amount to move the movable member toward said one position when the output value of the sensor device remains unchanged. When the sensor device produces a changed output value, the system drives the motor in a third amount to move the movable member toward said one position. Subsequently, the system drives the motor in a fourth amount when the output value of the sensor device is different from the output value before the motor is driven in the first amount, so as to move the movable member toward said other position. The system drives the motor in the second amount when the output values are the same so as to move the movable member toward said one position.

The present invention provides an integrated antenna with an identical ground member, in which the interference between the adjacent antennas can be suppressed while the antenna is miniaturized in not only the width direction but also the height direction. In the integrated antenna with the identical ground member, plural antenna elements having two different resonance frequency bands are disposed in an identical ground member. Each antenna element includes a first radiation portion corresponding to one of the resonance frequency bands and a second radiation portion corresponding to the other resonance frequency band. At a point where the two antenna elements are adjacent to each other, a dielectric material is disposed in one of radiation portions located inside the antenna element such that the dielectric material contacts the radiation portion.

A communication terminal includes a display device configured to display an image on the display device according to image display parameters; a processor to process the images data; and a communication interface to transmit or receive data, the communication interface configured to be coupled to a remote image processing device via a network. Unnecessary data is prevented from being transmitted, and it becomes possible to reduce processing loads on the terminals to thereby display only the focused image data section in a shared fashion between the terminals during the communication. When a communication is conducted in real time, it can be explicitly indicated on what section of image data a user of a terminal which is to transmit the image data and a user of a terminal which is to receive the image data are to focus each other's attention during the communication.

A technique is disclosed for accurate measurement of the distance and detection of an object such as a human body behaving in a complicated way and having a complicated reflection surface using the two-frequency Doppler method. Each of the two-frequency Doppler signals is subjected to the short time Fourier transform to produce a spectrum in a short time window. Based on restraints, it is determined whether the waveforms of the two spectra are analogous to each other or not, and only in the case where the waveforms are analogous, the Doppler signals of the particular time window are used for distance calculation. As a result, the Doppler signals having the phase information low in reliability are eliminated, and therefore high-accuracy distance measurement and object detection are possible.

A tape drawing-out mechanism for positioning a magnetic tape 91 as tensioned in a specified path of travel has a drive lever 6 having a cam follower 62 projecting therefrom, a tape drawing-out lever 5 having a tape drawing-out pin 51 for receiving the force of the drive lever 6 in a first step of a tape drawing-out movement, and an auxiliary lever 7 for receiving the force of the drive lever 6 in a second step of the tape drawing-out movement. The auxiliary lever 7 has a pin 71 projecting therefrom for pressing a face 54 provided on the tape drawing-out lever 5 to pivotally move the lever 5 to a tape drawing-out end position. The mechanism described precludes a great reaction from acting on the cam follower 62 and a cam groove 41 for giving a tape drawing-out drive force.

A surveillance camera comprising an image capturing portion having a rotational drive portion for rotatingly driving an image capturing lens about a pan axis and an initial position sensor providing a reference to the pan angle of the image capturing lens, a base for the image capturing portion to be attached thereto with the pan axis positioned toward a changeable direction, a controller electrically connected to the drive portion and the initial position sensor, and restrictive portion for mechanically restricting the permissible pan angle of the image capturing lens to different angles in accordance with the direction of the image capturing portion as attached to the base. The controller detects the direction of the image capturing portion as attached to the base based on the angle of rotation of the drive portion and the position of the initial position sensor.
