  • Publication number: 20140040677
    Abstract: A storage device includes one or more storages and one or more control devices to control writing data to and reading data from one of the storages. Each of the control devices includes a memory, a memory controller, and a processor. The memory controller controls writing data to and reading data from the memory. The processor determines whether the memory and the memory controller have error correcting functions respectively. The processor determines, when at least one of the memory and the memory controller does not have an error correcting function, whether an error is detected in first data expanded in a first memory region of the memory. The first data includes an error detecting code. The processor saves, when no error in the first data has been detected, the first data into a second memory region of the memory. The second memory region is different from the first memory region.

  • Patent number: 7957429
    Abstract: In order to increase the efficiency of large-capacity transmission, the continuity of divided signals generated by dividing a multiplexed signal is maintained and the original large-capacity multiplexed signal is restored. A signal dividing section divides a multiplexed signal to generate a plurality of divided signals in the STS or STM transmission interface format. A guarantee information adding section adds guarantee information for guaranteeing the continuity of the divided signals to each of the divided signals to generate transmission signals. A signal sending section sends the transmission signals via a transmission line in the transmission interface format. A signal receiving section receives the transmission signals. A signal restoring section restores the multiplexed signal by constructing the divided signals on the basis of the guarantee information.

  • Patent number: 7940651
    Abstract: A read address from a memory and a write address to the memory are transmitted from a VT pointer circuit on an active side to a VT pointer circuit on a standby side in order to eliminate a difference between pointer values of the VT pointer circuits on the active and the standby sides, which is caused by a difference between the phases of the read address from the memory and the write address to the memory of the VT pointer circuits on the active and the standby sides, and the read and the write addresses on the standby side are overwritten with the transmitted address values. As a result, the address values can be made to match both on the active and the standby sides, and also the pointer values can be made to match.

  • Patent number: 7761004
    Abstract: A fully charged battery or an unused battery is set in a battery box of a lighting apparatus. A user turns on an illumination electric source of the apparatus and selects the battery. A maximum number of lighting times Smax when the lighting apparatus causes manual full lighting M1/1 by using the selected battery is stored in a memory of a microcomputer or IC by a user according to an operating button or an instruction on a liquid crystal screen. Next, the user performs normal shooting. A lighting amount (TTL lighting, manual full lighting, or the like) when the user performs shooting is converted to manual full lighting M1/1 to be obtained as a number of lighting times. By comparing the obtained number of lighting times with the maximum number of lighting times Smax, how many times of lighting can still be performed at a maximum is calculated.
