Abstract: A data processing apparatus is disclosed, that comprises a large capacity memory means for storing a plurality of files, a memory means for storing move/copy history when a particular file is moved/copied from the large capacity memory means to a non-volatile memory, a reference means for referencing the history information stored in the memory means when the particular file is moved/copied from the large capacity memory means to the non-volatile memory, and a control means for prohibiting the particular file from being moved/copied from the large capacity memory means to the non-volatile memory when the reference means has detected that the history information is stored in the memory means.

Abstract: Technologies to transfer responsibility and control over security from player makers to content authors by enabling integration of security logic and content. An exemplary optical disk (200) carries an encrypted digital video title combined with data processing operations that implement the title's security policies and decryption processes. Player devices include a processing environment (e.g., a real-time virtual machine), which plays content by interpreting its processing operations. Players also provide procedure calls to enable content code to load data from media, perform network communications, determine playback environment configurations (225), access secure non-volatile storage, submit data to CODECs for output (250), and/or perform cryptographic operations. Content can insert forensic watermarks in decoded output for tracing pirate copies.

Abstract: A saddle type vehicle includes a down tube extending downward from a head pipe for supporting a front fork, a rear wheel pivot unit provided on the down tube, and a rear wheel suspension device for supporting a rear wheel of the vehicle such that the rear wheel can pivot substantially upward and downward around the rear wheel pivot unit. The rear wheel pivot unit is disposed before an engine in the advancing direction of the vehicle. The engine is attached to the rear wheel suspension device such that the engine can pivot with the rear wheel suspension device.

Abstract: A scooter includes a body having four pulleys at four corners of the body. A wire reeves through the pulleys. A head tube is connected to the body, and a handlebar stem with a front wheel rotatably extends through the head tube. A rear wheel is connected to the rear part. Two pedals are fixedly connected to the wire, and toothed belts extend through the pedals. Each pedal has two wheel sets. Each wheel set has a shaft on which a one-way bearing is mounted. A gear is connected on the the one-way bearing and is engaged with the toothed belts. Wheels of the wheel sets contact the ground, and the scooter moves by reciprocally shifting the pedals on the toothed belts.

Abstract: A kinetic energy generating mechanism includes a driving part, a transmission part, and a driven part. The driving part includes front and rear rollers separately mounted on a vehicle, and an actuating belt wound around the front and rear rollers. The transmission part is a transmission gear mounted to an end of the rear roller to rotate along with the same. The driven part is a driven gear mounted on a rear axle of the vehicle and meshing with the transmission gear, or may include front and rear driven gears wound around by a chain to mesh with the transmission part and mount on the rear axle of the vehicle, respectively. When a user walks or runs on the actuating belt, the latter rotates the front and the rear roller counterclockwise, and the driven part meshed with the transmission part is rotated clockwise to move the vehicle forward.

Abstract: A jogging kick scooter is constructed to include a rectangular open base frame, a track assembly formed of rolls and an endless belt and mounted in the open base frame, a steering control handlebar mounted in the front side of the open base frame to hold and control steering of a front wheel, two rear wheels bilaterally coupled to the open base frame at a rear side, and transmission gear sets respectively connected between the rear wheels and the wheel axle of the last roll of the track assembly and adapted to rotate the rear wheels when the user walks or runs on the track assembly.

Abstract: A jogging scooter is constructed to include a base holding a set of tracker rollers, two tracks mounted on the tracker rollers and arranged in parallel, a front wheel rack provided at a front side of the base, two front wheel holders respectively pivoted to the front wheel rack and linked by a link and supporting a respective front wheel, a steering column mounted on the front wheel rack and coupled to the link for steering control, a rear wheel axle mounted in a rear side of the base and supporting a pair of rear wheels, and two gears meshed together and respectively mounted on the rear wheel axle and the rear tracker roller for transmission of rotary force.

Abstract: A method of managing keys used by a digital content player on a computer system. According to the method, digital content data encrypted with a first encrypting key is decrypted using a first decrypting key, and re-encrypted using a second encrypting key. A second decrypting key is encrypted using a third encrypting key to produce an encrypted second decrypting key. In one preferred method, an encrypted first decrypting key that was encrypted using a fourth encrypting key is received, and the encrypted first decrypting key is decrypted using a fourth decrypting key to reproduce the first decrypting key. A digital content player for use on a computer system is also provided. The content player includes a decrypter that decrypts digital content data, which was encrypted with a first encrypting key, using a first decrypting key so as to produce the content data. An encrypter re-encrypts the content data using a second encrypting key and encrypts a second decrypting key using a third encrypting key.

Abstract: A vehicle suspension system for wheeled vehicles includes a split-beam trailing arm which is secured to the vehicle frame pivotably at one end for vertical swinging movement relative thereto. The other end of the trailing arm supports an air spring assembly. The split-beam trailing arm comprises a first member and second member which have respective connecting surfaces for assembling the first and second members together in a variety of orientations to accommodate varying spacing needs between the axle or trailing arm and the vehicle frame. The load centers on the trailing arm at the pivoted connected with the frame, the connection with the axle and the connection with the air spring assembly are generally aligned and extend from a point offset from the frame to the frame thereby reducing the torsional moment on the trailing arm. The first and second members are also symmetrical about a transverse plane.

Abstract: A tricycle which includes a treadmill walked by a rider in order to power the vehicle, the treadmill including an endless belt, on which the rider's feet are placed, and the treadmill driving a system of pulleys, that turn an axle on which the rear wheels are affixed.
