  • Patent number: 8134748
    Abstract: There has been a problem in that original image data should be saved with another name so as not to be altered, resulting in complexity and an increase in a necessary storage region. Image data are housed in a folder managed as a film metaphor and a database of photographic data 30b corresponding to each image data is prepared. When a desirable image processing is selected for desirable image data, the selected image processing is updated as modification information in the database structure. When display, output or print is actually required, various image processings are executed by referring to modification information on only a work area with original image data left. Therefore, it is possible to easily enjoy image modification or the like with the original image data left as they are.

  • Patent number: 7967125
    Abstract: A deformed-coin detector accurately detecting a deformed coin without being affected by a variation in transporting speed of a coin. A coin transported along a coin transporting face comes into contact with detecting elements of coin-thickness detecting bodies, the detecting elements move by a distance corresponding to the dimension of the coin in its thickness direction and simultaneously, light shielding portions of the coin-thickness detecting bodies move. A light detecting portion detects a light shielding amount that varies due to movement of the light shielding portions. A coin denomination determining unit determines a denomination of the coin transported along the coin transporting face and reads a reference light-shielding amount pre-stored in a reference light shielding amount storing unit regarding the denomination.

  • Patent number: 7693177
    Abstract: A navigational aid for use as an AIS apparatus includes a memory for storing information about previous use of individual time slots synchronized with transmission schedules of other stations and a signal detector for judging whether an information signal exists in a time slot specified in accordance with a synchronization timing signal based on the information stored in the memory and a result of monitoring of the behavior of a baseband signal obtained from a received signal on an IQ-plane. The navigational aid transmits information about own station based on a result of judgment by the signal detector. The monitoring of the behavior of the received baseband signal plotted on the IQ-plane can be accomplished by performing pattern recognition operation, for which a carrier sense technique, such as a support vector machine, subspace method or neural network, can be used.

  • Patent number: 7620022
    Abstract: A CPU of a TDMA communications apparatus examines whether a slot to be allocated for a next transmission is a first slot (S1). If the slot to be allocated is the first slot, the CPU examines whether there are any slots already allocated by other stations within a Selection Interval SI in a frame in which the next transmission of own station is to be allocated referring to a slot map in a memory and finds out a free slot within Selection Interval SI (S11). Then, the CPU allocates the free slot as a next transmit slot of the own station and sets the slot number of the free slot as the slot number of the next transmit slot (S12). Then, the CPU examines whether a slot adjacent to the next transmit slot of the own station is allocated to any of the other stations (S13).
