  • Patent number: 9747944
    Abstract: Zeotropic effects are created while an observer experiments with video data and speed controls of a rotary motor. A system facilitates user creation of a customized zoetrope animation disc by enabling a user to take a video of a repetitive motion (e.g., a person doing a jumping jack, a hand opening and closing, a person swinging back and forth on a swing, etc.). The system prompts a user to select a start point and end point to the video. The system further prompts the user to specify a number of frames desired for the animation disc. The animation disc is then printed for use on a rotary motor based on the user input.

  • Patent number: 8290349
    Abstract: The present invention relates to a playback apparatus, a method, and a program which can appropriately perform jump playback when content transmitted through a network is played back in real time. A terminal 3 receives stream data transmitted from a server 1, buffers the stream data, and plays back the buffered data. The terminal 3 has multiple buffers to allow content data of the positions of jump destinations that can be specified as a jump destination during jump playback to be pre-buffered in the multiple buffers. As a result, upon receiving a request for jump playback, the terminal 3 can start playback from a jump destination without delay, since the data of the jump destination has already been buffered. The present invention is applied to, for example, television receivers.

  • Patent number: 6671235
    Abstract: A method of, and apparatus for, defining disk tracks in magnetic recording media. The track-writing apparatus (20) is capable of forming tracks (340) with a track width (TW) and track spaces (350) with a space width (SW) on a magnetic media disk (70) having an upper surface (70S), wherein the disk comprises a magnetic medium with a thermal diffusion length (X). The apparatus comprises, in order along an optical axis (A1), a laser light source (30) capable of providing a pulsed laser light beam (B1), a light pipe (32), and illumination shaping optical system (40) that provides substantially uniform illumination over an exposure region (ER), and a phase plate (60) having a phase grating (210) with a grating period (p), arranged proximate and substantially parallel to the upper surface of the disk so as to form an periodic irradiance distribution (380) at the surface of the disk when the phase plate is illuminated with the exposure region.

  • Patent number: 6654547
    Abstract: A digital versatile disc (DVD) includes a read-only ROM area in which video is previously recorded, and a readable/writable RAM area. A lender DVD apparatus writes a playback/recording control program in the RAM area of the DVD to be rented. A user DVD apparatus reads the playback/recording control program from the RAM area of the rented DVD. Following the playback/recording control program, the user DVD apparatus receives digital broadcasting, extracts commercial messages therefrom, and writes the extracted commercial messages in the RAM area. Then, the user DVD apparatus reads the video from the ROM area and the commercial messages from the RAM area for playback. Then, the user DVD apparatus generates history data indicating how many times and which commercial message has been played-back, and writes the generated history data in the RAM area.

  • Patent number: 6632546
    Abstract: A recording layer 6 records and stores information and comprises a plurality of layers, namely a first layer 6a and a second layer 6b. The first layer 6a is made from a recording material which gives parallel directions to saturation magnetization and sublattice magnetization. The second layer 6b is made from a recording material which gives antiparallel directions to saturation magnetization and sublattice magnetization at room temperature. The recording material for the second layer 6b gives parallel directions to saturation magnetization and sublattice magnetization at around a read temperature.

  • Patent number: 6622276
    Abstract: A long time optical recording and repeated reproduction of multimedia information is possible. Using a printer system or printing process system, on a recording medium such as a sheet, the so-caled multimedia information in the form of dot codes (36) together with images (32) and characters (34) is recorded. The multimedia information includes audio information such as voices, image information obtainable from a camera and others, and digitally coded data obtainable from a personal computer and other. A pen-like information reproducing device (40) is manually moved to scan the dot codes (36) and to take in the dot codes. The original sound is generated by a voice output device (42) such as an earphone, the original image information is outputted on a display such as a CRT, and the digitally coded original data to a page printer or the like.

  • Patent number: 6609841
    Abstract: A system and method for achieving, while using a multimode diode laser and polarization-maintaining fibers, high signal-to-noise ratio in a magneto optical storage system. In particular, the system splits an incoming main light signal into two orthogonal polarization states, which then propagate over different distances before recombining. By pulsing the laser on and off at a high frequency and choosing an appropriate path difference for the polarization states, which is dependent upon the modulation frequency of the laser, the system eliminates first-order spectral polarization noise arising from a potential error in a key optical component.

  • Patent number: 6583945
    Abstract: A data cartridge and method for providing a write-securable storage medium that inhibits writing. The medium comprises a write-secure-type indicator in a predefined location that indicates the medium is of a type that is susceptible to write securing. Additionally, the medium comprises a write-secure-complete indicator in a predetermined zone of the disk that is not accessible to a user. When the write-secure-complete indicator is set by a host device, the setting is irreversible and consequently the data on the medium is protected, and additional writing onto any part of the medium is permanently prevented.
