Abstract: An unmanned air vehicle includes a generator that generates a flying force and also generates an air flow, a structural component, a microphone that outputs a first signal, a speaker, and a processor. The processor generates a second signal according to the first signal. The structural component surrounds a noise source of the generator, and includes a through-hole extending in a direction of the air flow. The through-hole is in a direction opposite to the direction of the air flow. An end, in the opposite direction, of the structural component corresponds to an end, in the opposite direction, of the noise source of the generator. An end, in the direction of the air flow, of the structural component extends, in the direction of the air flow, beyond an end, in the direction of the air flow, of the noise source of the generator.

Abstract: The present invention provides a transmitter which can suitably perform a transmission power control in a PT-RS port. In this transmitter (100), a control unit (101) determines a transmission power for transmitting a reference signal (PT-RS) for phase tracking and a data signal within a range in which the maximum transmission power for each antenna port is not exceeded. In addition, a transmission unit (105) transmits the reference signal for phase tracking and the data signal at the transmission power determined by the control unit (101).

Abstract: An encoder that encodes a current block in a picture includes circuitry and a memory coupled to the circuitry. The circuitry, in operation: selects at least one transform basis from among candidates for a transform basis which include a basis of a type-II discrete cosine transform (DCT-II) and at least one of a basis of a type-IV discrete cosine transform (DCT-IV) or a basis of a type-IV discrete sine transform (DST-IV); and transforms prediction error values of the current block, using the at least one transform basis selected. When the size of the current block is greater than a threshold size, the circuitry selects at least one transform basis after excluding at least one of the basis of the DCT-IV or the basis of the DST-IV from the candidates. The threshold size is at most half a maximum size to which the DCT-II is applicable.

Abstract: An anomaly detection device included in a communication network adopting a time-triggered protocol based on a time slot includes: a frame transceiver that receives frames; and an anomaly detector that detects an occurrence of an anomalous frame in accordance with a time slot among a plurality of time slots included in a cycle and the number of repeated cycles of the cycle for each frame. The anomaly detector detects an occurrence of an anomalous frame by verifying a statistic on the frames received while the cycle is repeated a predetermined number of times, which is at least once, against a rule indicating a reference range of the statistic.

Abstract: This communication device relays a relay signal to be transmitted to and from a first communication device and a second communication device, and is connected to a first apparatus. The communication device transmits the relay signal using a first transmission slot, and also transmits, using a second transmission slot, a signal having been transmitted from the first apparatus, said signal being transmitted within the transmission period of the first transmission slot in a frequency domain different from that of the first transmission slot.

Abstract: An encoder includes processing circuitry; and a memory coupled to the processing circuitry. Using the memory, the processing circuitry is configured to: change values of pixels in a first block and a second block to filter the boundary between the first block and the second block such that change amounts of the respective values are smaller than respective thresholds, the pixels being arranged along a line across the boundary; and encode a third block. The pixels in the first block include a first pixel located at a first position, and the pixels in the second block include a second pixel located at a second position corresponding to the first position with respect to the boundary. The thresholds include a first threshold and a second threshold corresponding to the first pixel and the second pixel, respectively. The first threshold is different from the second threshold.

Abstract: A decoder that decodes a current block using a motion vector includes: a processor; and memory. Using the memory, the processor: derives a first candidate vector from one or more candidate vectors of one or more neighboring blocks that neighbor the current block; determines, in a first reference picture for the current block, a first adjacent region that includes a position indicated by the first candidate vector; calculates evaluation values of a plurality of candidate regions included in the first adjacent region; and determines a first motion vector of the current block, based on a first candidate region having a smallest evaluation value among the evaluation values. The first adjacent region is included in a first motion estimation region determined based on the position indicated by the first candidate vector.
