A user apparatus has a determiner configured to determine whether a relationship degree indicative of a degree of depth of relationship between a first user who manages the user apparatus and a second user who manages an external apparatus that is located within a predetermined range from the user apparatus is at or above a threshold; an acceptor configured to, when a determination result by the determiner is affirmative, accept an input of an instruction that permits lending to the second user a usage authorization to use a service that is available to the first user on the user apparatus; and a lender configured to, when the acceptor accepts the input of the instruction, provide the external apparatus with authorization information to enable the service to be used on the external apparatus.

User apparatus and external apparatus

A security apparatus identifies a first user associated with a first terminal apparatus within an area of a house to which entry is limited by a lock apparatus, and a second user associated with a second terminal apparatus approaching the house. The security apparatus determines a requirement for unlocking for the second user, based on a relationship of the second user with respect to the first user, and then determines whether the requirement for unlocking is satisfied. When the requirement for unlocking is satisfied, the security apparatus controls unlocking of the lock apparatus.

A radio communication system includes: a visit information storage unit that stores plural visit information elements each indicating information on a visit to a cell visited by a user equipment; an event detector that detects an event that occurs in the user equipment; a cell identifier detector that detects a cell identifier that indicates a cell visited by the user equipment; and a location characteristic determiner that determines a location characteristic of the cell indicated by the cell identifier based on one or more visit information elements corresponding to the cell. The location to characteristic determiner determines the location characteristic of a cell visited by the user equipment when the event detector detects a no-cell-change event other than a cell-change event that indicates a change in the cell identifier.

A feature of the present invention pertains to a transmitter for transmitting data by video, the transmitter including a transmission data control unit that distributes the data to multiple colors constituting the video, and a display unit that converts the distributed data into a sequence of a predetermined color value with respect to each of the multiple colors and lighting the multiple colors in a communication area on a display in accordance with the sequence of the color value.

Transmitter, receiver, and method

A method to be executed by a user terminal for searching for locations of one or more wireless devices that are located within an area in which the one or more wireless devices can wirelessly communicate with the user terminal, wherein each of the one or more wireless devices periodically transmits a beacon signal. The method includes detecting a number of the one or more wireless devices that are located within the area based on the beacon signals; determining a transmission period for transmitting the beacon signals depending on the number of the one or more wireless devices; and instructing the one or more wireless devices that are located within the area to transmit the beacon signals in accordance with the determined transmission period.

Consciousness of environmental conservation is increasing nowadays, and there are power generators for a portable device and employing power generation schemes without a codischarge, such as solar power generation and hand-crank power generation. When, however, power is supplied, information indicating that the power is obtained from clean energy without a COdischarge is unknown at the portable-device side. When power is supplied from the power generator to the portable device, a power generation scheme identifier for identifying a power generation scheme is transmitted. The portable device identifies the power generation scheme identifier, and can recognize the power generation scheme of the connected power generator. A supplied power level is recognized based on a power level of the storage battery of the portable device at a time point of starting the power supply, and a power level of the storage battery at a time point of terminating the power supply. Since the power level in the storage battery is managed in this manner using the power generation scheme identifier, it becomes possible to determine whether or not the power generation scheme of the power in the storage battery is a clean scheme.

A shading area having a transmissivity in the range of 0 to 2% is formed at the center of a clear defect in a wiring pattern of a half tone mask. Semitransparent areas having a transmissivity in the range of 10 to 25% are formed, adjacently to shading area, in areas extending from the inside of the edge of an imaginary pattern having no defect to the outside of the edge. In this way, in the correction of the defect in the half tone mask, the working accuracy tolerable margin of the correction portion of the defect can be made large.

A speaking period required for a voice recognition processing is detected with a simple and robust approach. A speaking period is detected based on an EMG generated when a speaker speaks. A large amplitude is observed in an EMG as muscular activity is caused when a speaker speaks. By observing this, a speaking period can be detected. The EMG can be measured from the speaker's skin via electrodes provided on a mobile-type terminal. Since a mobile-type terminal is usually pressed to the skin for use, affinity between this use form and the present invention is very high.
