Abstract: 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.

Abstract: 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.

Abstract: A reproducing apparatus is provided. According to that reproducing apparatus, separately provided sound data and motion picture data coincide with each other in reproducing start timing with smaller discrepancy than the conventional techniques. The reproducing apparatus 1 synchronously reproduces separately provided motion picture data and sound data, comprising a motion picture reproducing unit 40 and a sound reproducing unit 50. The motion picture reproducing unit 50 includes a motion picture decoder 42 which decodes the motion picture data and a display control unit 44 which converts the motion picture data decoded by the motion picture decoder into an image signal for a display unit, to output the image signal to the display unit 60.

Abstract: A communication system including a network and at least two terminal units connected thereto. Each terminal unit includes a session controlling unit for controlling a session for enabling transmission/receiving of voice, image, handwritten data to/from the remote terminal unit individually, and a display unit for displaying the image and the handwritten data. The image data and the handwritten data are overlapped and displayed on a display of the display unit.

Abstract: A plurality of primary detection regions A to I are scanned by switching a beam width and a beam direction of an antenna. The primary detection regions A to I are formed such that one detection region overlaps at least one of other detection regions. A small region (any one of secondary detection region (1) to (14)) corresponding to a region provided by excluding a region corresponding to a sum of set of the detection regions where a detection object was not detected, from a region corresponding to a product set of the primary detection regions where the object was detected is specified as a bearing in which the object exists, based on detection results of the respective primary detection regions.

Abstract: Beams are irradiated in three directions by switching an irradiation direction of a mainlobe of an antenna by stages, and an echo is received from a detection object obtained in the mainlobe or a sidelobe in each irradiation direction. Then, reflection power intensity in each irradiation direction is found from the received echo, and pattern of relative variation of the reflection power intensity (power intensity pattern) in each irradiation direction is generated. Meanwhile, a detection region is divided into seven bearings “c” to “i” and a power intensity pattern when an object exists in each bearing is previously stored as a reference pattern in each bearing. Then, the bearing in which the detection object exists is specified by comparing the power intensity pattern obtained from the received echo with the reference pattern in each bearing.

Abstract: Provided are an intruding object detecting apparatus (a radio wave sensor) capable of setting an arbitrary detection region, an apparatus for setting the detection region and a setting processe. An intruding object detecting apparatus 51 is installed in a corner of a room 53, a coordinate system is defined in which a location of the intruding object detecting apparatus 51 is an origin thereof, and coordinates are a distance r from the intruding object detecting apparatus and a scanning angle &thgr; of a transmission antenna/reception antenna of the intruding object detecting apparatus, and a state corresponding to the coordinate system is stored (b) in a storage means; thereby enabling the detection region 52 of the intruding object detecting apparatus can be arbitrarily set. Moreover, the setting can be performed with ease using a reflector or a transmitter, or alternatively, using a setting apparatus constituted of the reflector and the transmitter, combined.

Abstract: 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.

Abstract: A VCR embodying the invention comprises a memory 78 for storing video signals to be recorded on the tape 10, a control circuit 77 for controlling rotation of a capstan and two reel tables to set various operation modes and controlling write and read of the video signals to the memory 78. The control circuit 77 executes repeatedly a first control operation wherein the tape 10 is moved in a forward direction recording the time-compressed video signals to be read from the memory means on the tape 10, a second control operation wherein the tape 10 is rewound up to a position closer toward a tape head than a position wherein the recording operation has been terminated, and a third control operation wherein the tape 10 is moved to the position wherein the recording operation has been terminated, and thereafter, follows to the recording operation. With the VCR, a transition recording can be performed even in an intermittent recording operation, and recording operation is not interrupted with recording check.

Abstract: 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.
