The first and second data units are stored on a data storage device. A controller is operable to update the second data unit, to partially update the first data unit by storing the updated second data unit in the first data unit and to store the partially updated first data unit in the data storage device.

Abstract: In a network system controlling a device at home via a network, a direct access management server easily registering a control device and the controlled device is provided. The direct access management server receives a control device and service management ID acquisition request transmitted by a service server in response to a request from the control device, generates a control device and service management ID for a combination of the control device and a service, stores the control device and service management ID on a storage unit, and transmits the control device and service management ID to the service server. Upon receiving a password acquisition request, the direct access management server generates a controlled device registration password and transmits the controlled device registration password to the control device via the service server.

Abstract: A controlled device executes processing for device authentication and processing for device registration, receives a response of registration completion from a direct-access management server, and sets an automatic connection flag indicating the registration is completed. When the automatic connection flag is not set, the controlled device establishes an always-on connection session with the direct-access management server after executing the processing for the device authentication and the processing for the device registration. When the automatic connection flag is set, the controlled device skips the processing for the device authentication and the processing for the device registration to enter processing for establishing an always-on connection session.

Abstract: A vehicular transmission has a structure which enables a reverse idle gear to absorb and reduce excessive back torque inputted from drive wheels. At the time of reverse traveling motion, a counter shaft and a reverse gear are connected to each other through the intermediation of a clutch mechanism, whereby the power of the counter shaft is transmitted from the reverse gear, a driven gear, a hollow shaft, and a drive gear to the drive shaft by way of a final gear. When a large back torque is inputted to the final gear from the drive shaft, the inputted back torque is transmitted to the drive gear, and is then further transmitted to the driven gear by way of the hollow shaft. Since the hollow shaft is thin-walled and has reduced rigidity, it undergoes circumferential twisting due to the back torque inputted, whereby the back torque is reduced.

The map data includes: a structure achieved by dividing the map into a plurality of mesh-like subdivisions and dividing the map-related information into units corresponding to the individual subdivisions; and a structure in which the map-related information is managed in units of subdivision sets each containing a plurality of adjacent subdivisions and the map-related information is used in the map data processing apparatus in units of the individual subdivision sets.

Abstract: A map update system includes: a navigation apparatus that provides guidance from a current position to a destination having been set based upon map data stored therein and downloads various types of information requested by a user; and a providing apparatus that provides the various types of information to be downloaded at the navigation apparatus, and: the providing apparatus transmits the various types of information and update information related to an update of map data to the navigation apparatus in response to a download request transmitted from the navigation apparatus; and the navigation apparatus issues a notice related to the update of the map data based upon the update information transmitted from the providing apparatus, while downloading the various types of information.

Abstract: Data is transferred between a plurality of networks which are not synchronized in clock with each other, without creating either an overflow or an underflow. Data output from a first DVCR is transferred to a second DVCR via a first IEEE-1394 serial bus, a first ATM/IEEE-1394 data transfer apparatus, a first UNI, a first ATM network, an NNI 101, a second ATM network, a second UNI, a second ATM/IEEE-1394 data transfer apparatus, and a second IEEE-1394 serial bus. The second ATM/IEEE-1394 data transfer apparatus stores data in a buffer for each flow and deletes or inserts an empty packet depending upon the amount of data stored in the buffer so as to prevent an overflow and an underflow. A deviation of a time stamp caused by the insertion or the deletion of the empty packet is gradually corrected.

Abstract: In a sensor device having a pressure detecting element and a temperature detecting element, a port portion has an opening portion from which a pressure medium is introduced to a pressure introduction passage of the port portion, and a lead wire connected to the temperature detecting element is disposed in the port portion to be fixed by a fixing portion at a tip end portion of the port portion. Furthermore, the temperature detecting element is disposed such that the pressure medium introduced from the opening portion passes the temperature detecting element and is conducted to the pressure detecting element through the pressure introduction passage. Because the temperature detecting element is disposed in the pressure introduction passage, a diameter of the port portion can be made small.
