Abstract: According to one embodiment, an electronic apparatus includes a processing circuitry configured to estimate a position at which electromagnetic noise occurs based on propagation data in communication between a first wireless device located at a first position and second wireless devices located at second positions, and position information indicating the first position and the second positions.

Abstract: According to one embodiment, an electronic apparatus is arranged at an interface between a first layer and a second layer in a base station, and includes a processor and a memory configured to store allocation information indicating a radio resource for a first control signal. The first layer is configured to transmit a physical layer signal to the second layer. The processor is configured to generate a second control signal based on the allocation information, generate a synthesis signal by adding the second control signal to the physical layer signal, and transmit the synthesis signal to the second layer.

Abstract: An impact producing actuator can vary energy to be applied to a shape memory alloy, depending on, for example, an ambient temperature. The impact producing actuator has a drive signal generation unit that generates a drive signal based on a single pulse signal generated in response to an input operation and outputs the drive signal, a switching element whose switching operation is controlled by the drive signal, and a shape memory alloy through which electric current passes for a period of time during which the switching element is turned on or off. The impact producing actuator is configured such that the period of time during which the switching element is turned on or off varies depending on the ambient temperature.

Abstract: A drive device includes: a base member having, on a surface, an operation base part made up of one or more operation recesses; and a movable member disposed to be opposed to the base member and having, on the opposing surface, operation projections to be inserted into the operation recesses. A shape memory alloy member is interposed between the base member and the movable member, and the movable member is moved so as to be separated away from the base member in response to the contraction of the shape memory alloy member when energized. The drive device includes a spring which is supported by the base member and bias the movable member so as to be separated away from the base member.

Abstract: A vibration generation apparatus includes a holder including a receiver disposed with a distance from a vibration target component on the outside thereof, an actuator supported by the receiver and configured to push out one side surface of the vibration target component, and a biasing unit supported by the receiver and configured to bias the other side surface of the vibration target component in a pushing-back direction. The biasing unit includes one or more insulating elastic members opening at both ends thereof and formed in a tubular shape, and the elastic members are interposed between the receiver and the vibration target component side surface in the state in which the elastic members are compressed in a tube diameter direction.

Abstract: A drive unit includes a base member having an operation base having operation recesses in a front surface, a movable member that is disposed to be opposite to the base member and has operation projections to be inserted into the operation recesses in an opposed surface, and a shape memory alloy member that is disposed between the base member and the movable member and shrinks by heat generated by passing an electric current. In conjunction with the shrinkage of the shape memory alloy member by the passage of the electric current, the movable member is moved in a direction away from the base member. The base member has a fixed portion in its middle in a core axial direction of the shape memory alloy member, to fix the middle on a support member.

Abstract: Various operation feelings are provided in, for example, an impact actuator. The impact actuator includes a drive signal output unit for outputting a drive signal in which the voltage of a single pulse signal is changed with time, and a shape memory alloy through which an electric current is caused to pass in a period corresponding to the drive signal.
