摘要： A power transmission device includes a power transmission coil, and a power transmission side processor. A power reception device includes a power reception coil receiving electric power from the power transmission coil, a power reception power supply charging the storage battery based on the received electric power and general-purpose power supply components, a power reception side processor periodically controlling a charging current to the storage battery, and a current sensor detecting the charging current. When a value of the charging current is outside a predetermined range, the power reception side processor calculates a feedback control parameter to the power transmission power supply based on a difference between the value of the charging current and a target current value, and transmits the feedback control parameter to the power transmission side processor. The power transmission side processor controls electric power from the power transmission power supply based on the feedback control parameter.

摘要： In a “local production for local consumption” network including a backhaul line formed by wireless multi-hop communication between a plurality of base stations, and a plurality of local service servers, communication speed is increased by appropriately selecting communication routes between the user terminals and the local service servers, and the power efficiency of the wireless communication by minimizing the power consumption of the overall system. A network control server collects information regarding the user terminals, the access points, and the local service servers, sets communication routes between the user terminals and the local service servers, groups of the base stations, those of the existing base stations and local service servers that are active so as to optimize a power efficiency of the overall network according to the collected information, and notifies the base stations, the local service servers or the user terminals of route information regarding the communication routes.

摘要： Provided are a radio transmission device and a radio transmission method capable of improving downlink and uplink throughput even when performing dynamic symbol allocation. In the device and the method, BS and MS share a table correlating a basic TF as a combination of parameters such as TB size used for transmitting only user data, an allocation RB quantity, a modulation method, and an encoding ratio, with a derived TF having user data of different TB size by combining L1/L2 control information. Even when multiplexing L1/L2 control information, Index corresponding to the basic TF is reported from BS to MS.

摘要： A program execution device capable of protecting a program against unauthorized analysis and alteration is provided. The program execution device includes an execution unit, a first protection unit, and a second protection unit. The execution unit executes a first program and a second program, and is connected with an external device that is capable of controlling the execution. The first protection unit disconnects the execution unit from the external device while the execution unit is executing the first program. The second protection unit protects the first program while the execution unit is executing the second program.

摘要： An electromagnetic wave absorbing sheet includes a metallic base and an electromagnetic wave absorption film formed on the metallic base. The electromagnetic wave absorption film contains MTC-substituted ε—Fe2O3, black titanium oxide, a conductive filler, and a resin. The MTC-substituted ε—Fe2O3 is a crystal belonging to the same space group as an ε—Fe2O3 crystal and containing Ti, Co, Fe, and at least one element selected from the group consisting of Ga, In, Al, and Rh. The proportion of the conductive filler to the electromagnetic wave absorption film is equal to or greater than 0.1% by volume and equal to or less than 10% by volume.
