A lighted helmet having a protective shell having: an outside surface, a plurality of lamps which emit light from the outside surface; a power supply, typically a battery; and a motion detecting switch in communication with the power supply and the plurality of lamps. When the helmet is worn by a user, even small movements of the head produce forces, which in turn, trigger the motion detecting switch.

Upon expiration of the time period, subsequent motion will retrigger the switch, once again activating the lamps. The process continues until the helmet is placed in a stationary position, at which time the lamps are extinguished upon expiration of the then active time period.

Some disk devices used for a disk array may shorten a total active time when they are turned on 24 hours a day in comparison to a case where the disk devices are turned on only when needed. The disk device's total active time shortens when the disk device is turned on 24 hours a day and is operated continuously 24 hours a day. As a result, the disk device's operation period shortens. Such disk device is not suited for 24-hour continuous operations. The disk array capacity increases year after year. There is a trend of increasing the number of disk devices to be mounted. The power consumption for disk arrays tends to increase. A computer accessing a disk array has a disk control instruction program which allows the disk array to turn on or off specific disk devices in it. The disk array has a disk power supply control instruction reception program and a disk power supply control circuit. The disk power supply control instruction reception program receives an instruction to turn on or off disk devices from the computer. The disk power supply control circuit turns on or off a disk device corresponding to an LU specified by the computer.

In transmission of paging information from a mobile network to a terminal device (200), the terminal device applies a discontinuous reception cycle to enter a sleep mode. Further, the terminal device determines an advance wakeup time (AW) for leaving the sleep mode. The advance wakeup time (AW) is advanced by an advancement time interval (DeltaA) with respect to a start of an active time of the discontinuous reception cycle. At the determined advance wakeup time (AW), the terminal device leaves the sleep mode and starts monitoring the downlink control channel with respect to paging configuration information transmitted by the mobile network. The paging configuration information defines a paging occasion for transmission of the paging information. On the basis of the paging configuration information, the terminal device monitors the paging occasion to receive the paging information from the mobile network.

Using this methodology, a wireless network can be self-forming or “ad-hoc” in nature. That is, the formation of the network does not depend upon the presence of a pre-determined central coordinator. Second, it can accommodate relatively rapid changes in network configuration, including changes in the number and location of the devices participating in the network, and changes in the channel conditions experienced by communication devices. Third, it can accommodate an extended network system where the population of devices that are able to communicate wirelessly, either directly, or indirectly via devices that also act as repeaters, may be spread over a relatively large geographic area. Fourth, it can provide robust Quality of Service through the use of time reservations or “slots” during which one device or a limited number of devices are allowed to transmit. Fifth, it can provide good power management qualities, such that there are mechanisms which allow devices minimize active time and to transition in and out of reduced power “sleep” states while still maintaining the ability to communication.
