摘要:
A radio communication CPU controls each section of a radio communication device included in a short distance radio communication network by using network setting information in a network setting storage section. A connection relation with a communication network (for example, the Internet) is set and transmission/reception of data to/from equipment included in the communication network via the short distance radio communication network is controlled. Thus, the network setting or the like for connecting to the Internet or the like is simplified for each portable equipment existing in the short distance radio communication network.

A signal transmission method applicable to prevention of modification or alteration of the playback mode information, such as copying management information or charging information. The playback mode information form a terminal 15P is data-converted for ciphering by a playback mode information appendage circuit 14 in a header appendage circuit 13 responsive to the key information from a terminal 15K and the resulting information comprised of the data and the playback mode information is outputted. The reproducing side effects data conversion on the ciphered playback mode information for deciphering, by a playback mode information detection circuit 26 in a header separation circuit 25, using the key information from a terminal 27K, for taking out the original playback mode information at a terminal 27P.

摘要:
A vehicle seat includes a seat back, a seat cushion, and a system for facilitating relieving of fatigue of a person sitting on the vehicle seat for many hours. The system includes an angle sensor installed within the seat back for sensing variations in an angle of a pelvic region of the person sitting on the vehicle seat, an active device installed within the seat back for pressure-supporting the pelvic region of the person, an actuating device connected to the active device for actuating the active device and a sequential control unit electrically connected to the angle sensor and the actuating device for controlling the operation of the actuating device, the angle sensor being constructed so as to send the sequential control unit signals representing values of variations in the angle of the pelvic region of the person, the sequential control unit being constructed such that, when a value represented by a signal sent to the sequential control unit from the angle sensor is more than a predetermined value, the sequential control unit sends the actuating device a command to actuate the actuating device, whereby the active device is actuated, to thereby control supporting pressure that is applied to the pelvic region of the person.
摘要:
A data transmitting method for preventing direct copying of digital bi-level signals. When processing input digital data from an input terminal 11 by circuits 13 to 16, modulating the data by a modulation circuit 17 and appending synchronization signals by a synchronization appendage circuit 18, the synchronization signals are appended using a synchronization format which is different from the synchronization format conforming to the standard and which is usually not used. For example, the synchronization pattern different from the regular synchronization pattern may be used, or the synchronization signal may be inserted at a position different from the regular position. If attempts are made for direct copying of the digital bi-level signal having such synchronization format, synchronization may be disengaged, for example, thus obstructing and prohibiting duplication.
摘要:
An optical disk D is composed of a first recording layer L.sub.1 and a second recording layer L.sub.2 each for two recording formats. Encrypted data is recorded on the first recording layer L.sub.1. Encrypting key data is recorded on the second recording layer L.sub.2. The encrypting key data is used for decoding the encrypted data. This recording makes easy reproduction of the recorded data quite difficult. If data recorded on a bit-formed portion may be reproduced by any means, the data signal recorded on the optical disk cannot be easily reproduced.
摘要:
A mat for a phonograph record turntable is made up of at least one rubber or other flexible enclosure defining at least one sealed interior space which contains a fluid material, preferably in the form of a viscous liquid, so as to provide a cushioned, vibration-damping record supporting surface which conforms to the shape of a warped or otherwise distorted phonograph record placed thereon. In order to avoid the accumulation of the liquid at any one portion of the mat when the turntable is not horizontally disposed, the interior of the mat may be divided into a plurality of liquid-containing spaces which are isolated from each other, as by partitions therebetween, and/or each interior space may further contain absorbent material which takes up the viscous liquid. The vibration-damping properties of the mat may be enhanced by providing solid particles which float in the viscous liquid.

摘要:
A data transmitting method, a data recording apparatus, a data record medium and a data reproducing apparatus are provided to disallow the encryption to be easily decoded and keep the secrecy of key information higher. The data transmitting apparatus includes an error correction coding process block. In the block, an input converting circuit operates to perform a logic operation with respect to the information data from an interface circuit 12 according to the key data. The converted information data is sent to an encoder 15 for generating parity data. This parity data is mixed with information data before conversion in a mixing circuit. The error correction coding block operates to send the resulting data to a modulating circuit 17 for modulating the data. The modulated data is recorded on a disk record medium.
