A memory card includes a non-volatile memory, a memory controller for controlling the operation of the memory card. The memory controller is capable of providing an interface with outside according to a predetermined protocol, and performs error detection and correction of the memory information at regular time intervals or at the timing of connection of electric power supply, independently of reading out the memory information according to external access request. Therefore, it is possible to improve reliability of data retention in the non-volatile memory without the host device reading out the memory information from the non-volatile memory of the memory card.

A shock-absorbable electricity-producing apparatus comprises an electricity generator and an electricity-producing module. The electricity-producing module includes a rack, first and second gears, and a spring buffer. The rack is synchronously driven by a shock absorber. The spring buffer is located between the first and second gears. The first and second gears are engaged with the rack and an axial gear of the electricity generator, respectively. An electricity output terminal of the electricity generator is connected to an electric device. As a result, the rack drives the first gear by means of gravity drop that forms during movement of the shock absorber to enable the electricity generator to produce electricity. Consequently, the shock-absorbable electricity-producing apparatus absorbs shocks and produces the electricity insensibly without causing burden and resistance.

A management system of a machine equipped with a driving-power source reads out maintenance conditions from a storage means of maintenance management information when data and conditions, concerned about a maintenance management of a machine, the features of the machine, and so on, including the maintenance conditions, are inputted from the input means. Then, information about predicted maintenance management under a certain operation time of the machine is predicted with reference to the maintenance conditions. Subsequently, the information about the predicted maintenance management is represented on a display means. Furthermore, a maintenance predicted value is previously stored in a data base or the like with respect to the maintenance within an operation time under the contract or within a contract term for each of a plurality of contract ranks. A maintenance actual result value of the machine being entered is accumulatively stored. After a termination of the maintenance contract of the machine, the maintenance predicted value that corresponds to a model and a contract rank of the machine is read out, and simultaneously the maintenance actual result value of the machine is read out, followed by making a judgment whether the maintenance actual result value is larger or smaller than the maintenance contract predicted value.

An updating system able to easily and cheaply update music information in a terminal having a memory function unit storing music information of track data and music database information.A broadcasting apparatus 20 is configured by a broadcasting side memory function unit 21 for storing music information including track data and music database information and a transmission function unit 23 for broadcasting the music information on a broadcast channel, and a terminal 30 is configured by a reception function unit 31 for receiving the broadcast wave thereof, an extraction function unit 32 for extracting the music information from the received broadcast wave, and an update function unit 33 for updating the information in the reception side memory function unit 34 with the extracted music information.

A plurality of images are classified into hierarchical categories. A degree of importance for each of the categories is set according to at least one of: the number of images therein, the number of images in an upper-level category, the number of categories related to the category, the number of hierarchical levels below the category, and the number of hierarchical levels from the uppermost level to the level of the category.

A secondary battery charging system includes a secondary battery charging device and a power generation device that generates a charging current. The secondary battery charging device controls the charging a secondary battery, which has a protection timer that counts a first elapsed time from a start of charging. The secondary battery charging device includes a charging switch that controls a supply of the charging current, a time management timer portion that counts a second elapsed time starting from a point at which the charging switch becomes conductive and performs a charging stop determination and that counts a third elapsed time starting from a point at which the charging switch is cut off and performs a charging start determination, and a charging control portion that causes the charging switch to be conductive or cut off based on results of the charging stop determination and the charging start determination.

A passenger vehicle for carrying a golf bag includes first and second front wheels and a rear wheel, a frame that may be folded into a compact position, gearing, and a steering mechanism. The frame includes a cross bar extending between the first and second front wheels, first and second front bars connected to a rear bar at a hinged connection, and a down tube connected to the cross bar, wherein the rear bar includes a receiving mechanism for releaseably receiving the down tube. The gearing includes a cassette secured to an axle extending through the cross bar. A steering mechanism for providing directionality includes a steering member within the rear bar. A first golf bag support is connected to the first and second front bars and a second golf bag support is connected to the cross bar.

A method for performing privacy-preserving or secure multi-party computations enables multiple parties to collaborate to produce a shared result while preserving the privacy of input data contributed by individual parties. The method can produce a result with a specified high degree of precision or accuracy in relation to an exactly accurate plaintext (non-privacy-preserving) computation of the result, without unduly burdensome amounts of inter-party communication. The multi-party computations can include a Fourier series approximation of a continuous function or an approximation of a continuous function using trigonometric polynomials, for example, in training a machine learning classifier using secret shared input data. The multi-party computations can include a secret share reduction that transforms an instance of computed secret shared data stored in floating-point representation into an equivalent, equivalently precise, and equivalently secure instance of computed secret shared data having a reduced memory storage requirement.

A test system is provided for simulating pre-tensioner systems that use pyrotechnic gas generators. In a preferred form, the test system includes a pneumatic cylinder energized by pressurized air from an accumulator and passing through a fast acting ball valve. A substantially linear relationship is established between accumulator pressure and the time rate of change of acceleration of a piston in the pneumatic cylinder. Use of the test system allows improved evaluation of seat belt systems employing pre-tensioners with pyrotechnic gas generators.
