摘要:
Disclosed is a wireless communication apparatus for receiving a code-spread transmission signal. The wireless communication apparatus includes: an RF section; and a baseband section, wherein, in the baseband section, despreaders of an integral submultiple, which is 1/n1, of the number of chips of a spread code are arranged in parallel, and there is provided a propagation measurement section that measures a propagation channel by using the plurality of despreaders a plurality of times in a time-division manner and performing despread of each period corresponding to a chip rate of the spread code.

摘要:
In a registered card issuing information supply device 131, the registered card issuing information is encrypted, and the encrypted registered card issuing information thus obtained is transmitted through a transmission medium 121 to a registered card issuing machine 101. In the registered card issuing machine 101, the encrypted registered card issuing information from the registered card issuing information supply device 131 is received and registered. When the registered card issuing machine 101 is allowed to communicate with the IC card 2, it transmits the encrypted registered card issuing information thus registered to the IC card 2. In the IC card 2, the encrypted registered card issuing information from the registered card issuing machine 101 is decoded, and the registered card issuing information thus obtained is stored.
摘要:
The at least five simultaneous equations include at least five unknown quantities, namely, a reference time, an error of a clock for measuring a diffusion-code reception time for each of the satellites and the 3-dimensional coordinates of the receiver. The diffusion code is transmitted from each of the satellites at a diffusion-code transmission time expressed as a sum of a time having a value represented by digits expressing a number equal to or greater than one unitary time corresponding to one period of the diffusion code and a time having a value represented by digits expressing a number smaller than the unitary time. The time represented by the digits expressing a number equal to or greater than the unitary time is represented by a sum of the reference time which is a time common to all the satellites and the differential time which varies from satellite to satellite. Accordingly, the position of a receiver can be found even in a condition where latest time information cannot be obtained or a condition where a signal transmitted by each satellite is weak such as a condition immediately following activation of the receiver so that a diffusion-code transmission time ti of the satellite cannot be confirmed.

To be able to maintain compatibility of a plurality of data even when a hazard is caused in the midst of writing the plurality of related data, a first region stores physical block numbers #00H through #03H of physical blocks constituting a data region respectively in correspondence with logical block numbers %00H through %03H, for example, when a request of writing data is made to the logical blocks %00H and %02H, the data are respectively written to, for example, physical blocks #04H and #05H which are updating blocks for updating data in physical blocks constituting the data region and block numbers #04H and #05H of the physical blocks are stored to a second region respectively in correspondence with the logical blocks %00H and %02H.
摘要:
In information communication system and method applicable to an in-vehicle networking architecture, at least one first electronic equipment which is enabled to serve another electronic equipment with its function and at least one second electronic equipment which is enabled to make use of a function which another electronic equipment serves are connected to a common communication bus (network). An equipment managing apparatus connected to the common communication bus stores a function serving information representing the function that the first electronic equipment can serve and a making-use-of function information representing the function of which the second electronic equipment can make use. If both contents of the function serving information and the making-use-of function information are coincident with each other, the second electronic equipment makes use of the function of the first electronic equipment.

An electric motor includes a magnet rotor which is placed with an air gap interposed between it and a stator and has a magnetic pole portion formed from a plastic magnet which swells by hydrogen bonds, an inverter circuit, a DC-voltage conversion portion, a driving logic control portion, a supply current value control portion, a current value designation portion, a reference current value designation portion, and a correlation designation portion, wherein the correlation designation portion determines an average current value by changing the average current value linearly or non-linearly with respect to a reference current value, and the magnetic pole portion absorbs moisture to swell, thereby making the air gap smaller, at higher humidity than a reference humidity.
摘要:
When transmitting position/time information calculated by means of a GPS function to a server apparatus, authentication is carried out with the server apparatus. The position/time information may be certified as legitimate measured by a portable apparatus with a GPS reception function employed by a user. When transmitting information related to the position and the time acquired from a portable phone terminal having the GPS function and a network function by means of the GPS function to the server apparatus, authentication is carried out between the portable phone terminal and the server apparatus. The position/time information is transmitted to the server apparatus, only if the server apparatus is authenticated as a legitimate counterpart for connection.

The position/time information is transmitted to the server apparatus, only if the server apparatus is authenticated as a legitimate counterpart for connection. A secret key holding section is provided for holding different secret keys for different apparatuses. The position/time information measured based on an electromagnetic wave received from a positioning satellite is digitally signed by means of the secret key. The identification information and the position/time information having the digital signature are then transmitted to a counterpart.
