A method and apparatus are disclosed for reclaiming solid state storage with limited write cycles such as flash memory. Through the use of shared storage for common data patterns, physical space may be conserved or reclaimed in a solid state device. The apparatus may use internal mappings and/or external device drivers to handle the reclamation of unused space. By enabling reclamation of physical space, the disclosed systems, apparatus, and methods may provide more efficient read and write access and improved wear leveling.

The invention relates to a process of producing fermented milk or milk powder, including removing ions from milk, and reducing the dissolved oxygen concentration in the milk, followed by subjecting the milk to a heat treatment, as well as concentrated milk and milk powder with good flavor and an effect of improving physico-chemical properties as a raw food material, which have never been found in conventional concentrated milk and milk powder.

A battery pack is disclosed. The battery pack includes a battery, an impact sensor, a processor and a memory. The impact sensor is capable of generating an impact signal in response to a detection of an impact on the battery pack. The processor is capable of generating impact information based on the impact signal, and processor continues to count a number of charging times to the battery after the generation of the impact information. The memory is capable of storing the impact information and the number of charging times. The processor can refer to the memory to deliver a control command to a battery charger so that the battery can only be charged up to an allowable charge capacity smaller than a full charge capacity after an occurrence of an impact when the battery pack is attached to the battery charger. The charging to the battery stops when the number of the counted charging times reaches a predetermined number of allowable charging times that is allowed after the generation of the impact information.

A power control method for a magnetic disk unit is disclosed. The method includes identifying a type of a last instruction sent to a magnetic disk unit and, in response to identifying the type, setting a wait time that varies according to the type. In response to the wait time having elapsed after a completion of processing ordered by the last instruction, an idle instruction is sent to the magnetic disk unit for placing the magnetic disk unit in an idle state in which power consumption is reduced.

A light detecting apparatus has a two-axis deflector such as a two-axis mirror capable of controlling the deflection of a light beam. The apparatus realizes a sure and speedy light beam search operation without increasing deflecting frequencies of the two-axis deflector. In the light detecting apparatus, a digital signal processor (3) generates two periodic signals having different frequencies to separately control deflective operations in two axial directions of the two-axis deflection mirror (1). A light beam from the two-axis deflection mirror (1) draws a locus on a two-dimensional position sensitive detector (2). Along the locus, the search operation is carried out to find an orientation of a light emitting element that emits a light beam toward the two-axis deflection mirror (1).

A method to reduce the power dissipation of a system by omitting an unnecessary CPU throttling operation in a power management apparatus that performs the CPU throttling operation. A power management apparatus 10 is constituted by an event detecting section 12 to detect an event in a system, an activity detecting section 14 to decide whether the system is in a busy state or in an idle state by checking whether or not there is activity in the system, and a clock control section 16 to execute CPU-clock control. The control section 16 does not perform an unnecessary CPU throttling operation, by stopping the CPU throttling operation when the system is in the idle state and performing the CPU throttling operation only when the system is in the busy state. With this, the power dissipation of the system can be considerably reduced.

A communication route guidance system provides exchange of data between an information center and each of a plurality of mobile units such as vehicles. The information center has the latest road data and searches it to prepare recommended route guidance data in response to a request from the mobile unit. The reccommended route guidance data is divided into a plurality of data segments, each usable as an independent guidance instruction in the mobile unit. The mobile unit has stored therein road data similar to the road data in the information center and determines if data communication with the information center is available. In a case where the mobile unit can not communicate with the information center, the mobile unit prepares route guidance based on the road data stored in the mobile unit. It thereby becomes possible to guide the user even in the case that the mobile unit can not communicate with the information center. Even in a case where a communication link is disrupted during transmission of route guidance data to the mobile unit, the mobile unit can effectively prepare whole route guidance data in combination with already-received route guidance data and additionally prepared route guidance data by reference to the road data stored in the mobile unit because the already received route guidance data is structured to be usable independently.

A radar apparatus is provided that can correctly extract the necessary point for a determination related to the safe travel of one's automotive vehicle among objects such as automotive vehicles moving at an angle in front and constructed objects. The radar apparatus of the present invention provides antennas that transmit beams in a plurality of directions and receive the reflected waves from objects as received signals. The objects that generated these reflected waves are detected. In addition, this radar apparatus provides a reflected location detection device that detects the reflected locations that are the generation source of the reflected waves for this plurality of directions, a grouping device that groups each of these detected reflected locations into a group of single or plural reflected locations assuming they belong to the same object, and a device that extracts reflected locations having the shortest distance from the moving body from among these grouped reflected locations to serve as reference points related to the safe travel of this moving body.
