  • Publication number: 20190196476
    Abstract: In automatic travel control of a flying device towards a target, when a current distance from the target is large in comparison to a prescribed distance threshold, a controller of the flying device performs velocity feedback PID control to control the flight propulsion unit of the flying device. When the current distance becomes small in comparison to the prescribed distance threshold, the controller performs a hybrid of the velocity feedback PID control and position feedback PID control to control the flight propulsion unit such that as the flying device approaches the target, the position feedback PID control becomes more dominant than the velocity PID control. The processor calculates a weighted average of the respective manipulated variables with dynamically adjusted weights to achieve the hybrid control.

  • Publication number: 20190094885
    Abstract: A flying device includes a propulsion unit, a distance sensor, a controller, a determiner and a control modifier. The propulsion unit enables the flying device to fly in air. The distance sensor determines a distance from the flying device to a reference plane. The controller controls an altitude of the flying device based on a value output from the distance sensor. The determiner determines occurrence of an environmental change due to a shift of the reference plane. The control modifier modifies control of the controller in a case in which the determiner determines the occurrence of the environmental change.

  • Patent number: 8653350
    Abstract: A performance apparatus 11 extends in a longitudinal direction to be held by a player, and is provided with an acceleration sensor 23. CPU 21 of the performance apparatus 11 gives a sound source unit 31 of a musical instrument unit 19 an instruction (note-on event) to generate a musical tone. CPU 21 generates a note-on event indicating a sound-generation timing represented by a time when an acceleration-sensor value of the acceleration sensor 23 exceeds a first predetermined value and thereafter has decreased to a value less than a second threshold value ?, which is less than a first threshold value ?, and gives the musical instrument unit 19 the generated note-on event to generate a musical tone.
