Abstract:
A terminal apparatus acquires setting information for controlling whether a storage area held by the non-volatile storage medium is to be used or not, from an external apparatus connected via a network, when the terminal apparatus is activated. The terminal apparatus updates area definition information defining the structure of storage areas in the non-volatile storage medium so that the storage area the use of which is restricted is in a state which cannot be recognized by the operating system, if the acquired setting information indicates that the use of the storage area is restricted. The terminal apparatus performs activation processing of the operating system after the update processing of the area definition information ends, if the acquired setting information indicates that the use of the storage area is restricted.
Abstract:
An information processing apparatus includes: a physical quantity detector unit which transforms a physical quantity into an electric signal and provides a detected value represented by the electric signal; a physical quantity determiner unit which determines whether the detected value is larger than a given threshold value; a timer unit which measures a time period during which it continues to be determined that the detected value is not larger than the given threshold value, in response to the determination that the detected value is not larger than the given threshold value after it is determined that the detected value is larger than the given threshold; a transmitter unit which transmits a request signal for requesting transmission of data, when the time period measured by the timer unit transcends a first given time threshold; and a receiver unit which receives transmitted data which is transmitted in response to the request signal.
Abstract:
To provide a memory product controller, a memory product control method, and a memory product storing a computer program, capable of realizing a multi-function memory product, without increasing the cost, by grouping a plurality of memory products. In a memory product controller, information identifying a memory product and an operating condition of the memory product are stored in association with information identifying a group, and when reading/writing is performed on one memory product belonging to a predetermined group by a reader/writer for a memory product, reference is made to an operating condition storage unit, and when other memory products having the similar operating condition are present in the same group, instruction information to perform reading or writing on one or a plurality of other memory products belonging to the same group and having the similar operating condition is transmitted to the reader/writer.
Abstract:
An apparatus for determining a position of a mobile wireless station comprises means for determining the position of the mobile wireless station in accordance with a position of a first reference wireless station, a position of a second reference wireless station, a first relative angular direction between the mobile wireless station and the first reference wireless station, and a second relative angular direction between the mobile wireless station and the second reference wireless station.
Abstract:
An information access system comprises: antennas arranged at respective different positions and used for communicating with contactless information storage devices that pass through a predetermined region substantially simultaneously; reader devices coupled to the respective antennas and adapted to communicate with the contactless information storage devices; and a control unit for controlling the reader devices and transmitting, to another apparatus, data received from the reader devices. In response to a control signal received from the other apparatus, the control unit controls predetermined one of the reader devices to transmit an RF identification request signal to the predetermined region via the antenna. The reader devices receive RF response signals from the contactless information storage devices via the antennas, then reproduce identifications, and then provide the reproduced identifications to the control unit. The control unit receives the reproduced identifications, and then processes redundant identifications in the received identifications so as to produce distinct identifications having no redundancy.
Abstract:
An information access system comprises a reader/writer for continually transmitting an ID request signal at a first frequency and being continuously ready to receive an RF signal at a second frequency, and an active contactless information storage device having a receiver for sensing a carrier of an RF signal at the first frequency, and a transmitter for transmitting a response signal at the second frequency when the ID request signal is received. When the receiver senses a carrier of an RF signal at the first frequency in a particular predetermined period, the receiver receives further the ID request signal, and, in response to the ID request signal, the transmitter transmits a response signal at the second frequency carrying an ID of the storage device stored. In the carrier sensing, the controller causes the receiver to be in an active state and the transmitter to be in an inactive state in the predetermined periods. When the receiver attempts to sense a carrier of the RF signal at the first frequency in a particular predetermined period but detects no carrier, the controller controls the receiver and the transmitter to maintain the inactive state during a sleep period between the particular predetermined period and the subsequent predetermined period.
Abstract:
A configuration notification unit monitors internal messages generated by an operating system of a computer related to a device configuration process for plug and play devices coupled to the computer via a serial bus interface. The configuration notification unit outputs a real time warning to the user when it is unsafe to change the number of devices coupled to the computer. In a preferred embodiment, the configuration notification unit include a message handler coupled to an indication unit.
Abstract:
A module which may be connected to an I/O port of a notebook computer to provide an enhancement to the number of connectivity options available to a user of the computer. The module houses a set of connectors, some or all of which may be specialized ones not normally found on the computer. The connectors are electrically connected to an I/O port of the computer by a flexible cable that allows the module to be easily positioned or re-positioned by the user. The flexibility of the connection allows the user to easily satisfy the line of sight requirement when using the infrared port for data transmission.
