  • Publication number: 20210258716
    Abstract: [Object] To provide a mechanism that makes it possible to control a process of determining a position in accordance with a radio propagation environment. [Solution] A communication device comprising: a wireless communication section configured to receive wireless signals from another communication device; and a control section configured to calculate a reliability parameter serving as an indicator that indicates whether a first incoming wave serving as a signal detected as a signal that meets a predetermined detection standard is an appropriate process target, among the wireless signals received by the wireless communication section, and control a positional parameter determination process of determining a positional parameter indicating a position of the other communication device on a basis of the first incoming wave, on a basis of the reliability parameter.

  • Publication number: 20210243054
    Abstract: A communication device is configured to correlate a first signal with a second signal at a designated interval, the second signal corresponding to the first signal and being received by the communication device where the other communication device transmits a signal including a pulse as the first signal, convert a correlation computation result that is a result of correlating the first signal with the second signal at the designated interval into a format including a matrix product of an expanded modal matrix and an expanded signal vector, the expanded modal matrix including a plurality of elements indicating the correlation computation result obtained when assuming that the signals are received at respective set times, the expanded signal vector being a vector including a plurality of elements, each of which indicates whether or not there is a signal received at each of the set times and amplitude and phase of the signal.

  • Patent number: 10990433
    Abstract: An apparatus determines a similarity of names of a plurality of virtual machines, and divides the plurality of virtual machines into clusters based on a result of the determination such that virtual machines having a value that represents the similarity of the names that is equal to or less than a given threshold are included in a first cluster and virtual machines having a value that represents the similarity of the names that is greater than the given threshold are included in a second cluster. The apparatus places virtual machines included in the first cluster on different host machines.

  • Patent number: 9896060
    Abstract: There are provided a buckle switch that detects an insertion of a tongue into a buckle of a seatbelt and an ejection of the tongue from the buckle, a signal transmitting section that wirelessly transmits a signal showing a state of the buckle switch, and an attaching detection control unit that controls the signal transmitting section such that the signal transmitting section transmits different signals that correspond to a first time lasting from the insertion of the tongue into the buckle until the ejection of the tongue from the buckle or a second time lasting from the ejection of the tongue from the buckle until the insertion of the tongue into the buckle.

  • Publication number: 20170305387
    Abstract: A buckle switch-and a microcontroller are provided. A power supply is connected to the buckle switch, which switches the connection with the power supply between a connected state and a disconnected state. The microcontroller is connected with the buckle switch and includes a removal switch input port and a removal control port. The removal switch input port detects the state of the buckle switch. The removal control port is connected to the buckle switch-via a pull-down resistance and controls whether the pull-down resistance operates. The microcontroller controls the removal control port such that the pull-down resistance does not operate when the buckle switch is in the connected state and such that the pull-down resistance does operate when the buckle switch is in the disconnected state.
