  • Patent number: 11972073
    Abstract: An electrostatic input apparatus is provided. A measuring unit measures capacitance at a plurality of coordinates of an electrostatic coordinate input unit. A converting unit obtains a reference value of the capacitance and converts the capacitance to difference values according to a distance between the electrostatic coordinate input unit at the coordinates and a finger. A first coordinate calculating unit calculates barycentric coordinates of a contact portion from the difference values for the plurality of coordinates. A cycle determining unit determines whether the difference values at coordinates on a circumference of a circle with a predetermined radius centered on the barycentric coordinates exhibit periodicity of two cycles in one round along the circle. An operation determining unit performs, when the cycle determining unit determines that the difference values exhibit periodicity of two cycles, a determination that an input operation using two or more fingers has been performed.

  • Publication number: 20230177968
    Abstract: A central command system may determine a mission plan for resilient execution by a swarm of drones comprising one or more sensors to capture data in accordance with the mission plan. The mission plan may specify requirements for fault tolerance or parallelism and a redundancy structure for the swarm. The mission plan may be transmitted to a remote drone swarm controller device that determines a swarm configuration based on the mission plan and available drones. The controller may transmit instructions regarding the swarm configuration to dispatch a resilient swarm of drones. During execution of the mission plan, drones in the resilient swarm may be monitored by other drones in the swarm, by the remote drone swarm controller, and/or by the central command system. The redundancy structure provides for failover options for one or more drones in the resilient swarm.
