| 20110145290 | ROUTE SEARCHING APPARATUS AND ROUTE SEARCHING METHOD - A route searching apparatus includes a travel route accumulation unit, an algorithm selection unit to select route searching algorithms to meet the preference of a user based on the accumulated travel routes, and a route searching unit to perform a route search up to a destination by using the selected algorithms. Preferably, the algorithm searching unit searches for each of the travel routes accumulated in the accumulation unit by means of several algorithms, calculates, for each algorithm, a match rate between the searched route and the actual travel route, and selects an algorithm of the highest match rate. Also, it is preferable that a condition common to roads avoided by the user is extracted from the accumulated travel routes, and a route search is performed by adjusting search costs so as to make such roads less prone to be selected. | 06-16-2011 |
| 20100323694 | MOBILE RADIO COMMUNICATION SYSTEM AND RADIO COMMUNICATION METHOD - In a mobile radio communication system of the cognitive radio method, a database device has a use state table indicating a probability that each frequency band is used for each period of time and for each location. An on-vehicle terminal acquires a frequency band having the highest probability that the band is empty at the current time and the current location according to the use state table and performs a radio communication by using the frequency band. The use state table is preferably created by a statistical process using the database device which acquires the use states of frequency bands of various locations and times by using respective vehicles as probe cars. Thus, it is possible to detect the frequency of the empty state in a short time. | 12-23-2010 |
| 20100248644 | WIRELESS DEVICE - A wireless device includes a baseband unit and front-end units that are provided in individual housings. The baseband unit and the front-end units are connected to each other by wire. A transmitter for synchronization that converts a signal based on a reference clock into a radio signal and transmits the radio signal as a clock synchronization signal is provided in any one of the housings, and receivers for synchronization that receive the signal for the clock synchronization and PLLs that generate a clock synchronized with a reference clock signal which is obtained from the received clock synchronization signal are provided in the housings other than the housing having the transmitter provided therein. In order to simultaneously process a plurality of wireless devices having different symbol rates, it is preferable to provide the transmitter, the receiver, and the PLL for each reference clock. | 09-30-2010 |
| 20100107005 | PROCESSOR OPERATION INSPECTION SYSTEM AND OPERATION INSPECTION CIRCUIT - A processor operation inspection system includes a processor and an operation inspection circuit that inspects an operation of the processor. When a program under execution changes from one predefined state to another state, the processor outputs a state switching signal indicating a transition of its state, a state signal indicating a current state to the inspection circuit. The inspection circuit includes a state register that stores the state of the processor, a combinational logic circuit that calculates, according to the stored state of the processor and the state switching signal, a new state to be taken by the processor, and a comparison circuit that inspects the operation of the processor by comparing the calculated new state to the state of the processor inputted as the state signal. | 04-29-2010 |
| 20100080168 | PROBABILISTIC ROUTING FOR VEHICULAR AD HOC NETWORK - A probabilistic method of determining a second vehicle in the VANET to which a packet is to be forwarded from a first vehicle is provided. The method includes determining the second vehicle to forward the packet from the first vehicle based on pre-calculated expected latency data corresponding to the second vehicle, and forwarding the packet from the first vehicle to the determined second vehicle. The expected latency data is indicative of the latency expected for communication of the packet from the first vehicle to the destination if the packet is forwarded from the first vehicle to the second vehicle, and is calculated in advance of the step of the determining the second vehicle to forward the packet. The second vehicle to forward the packet may also be determined based on pre-calculated communication probability data corresponding to the second vehicle in addition to the pre-calculated expected latency. | 04-01-2010 |
| 20100036972 | Reconfigurable computing device and method for inspecting configuration data - A reconfigurable computing device includes a reconfigurable logical device of which a circuit logic can be changed based on configuration data, a storage part to store beforehand input-output attributes of input-output parts of the reconfigurable logical device, and a verification part to verify the configuration data by making a comparison between information on the input-output parts in the configuration data and the input-output attributes stored in the storage part. With this, it is possible to inspect the configuration data of the reconfigurable logical device by a simple method. | 02-11-2010 |
