Abstract: A movement control system is a movement control system of a moving body configured to be moved by a driving system. The movement control system includes a planner, a corrector, and a controller. The planner is configured to execute an update process of updating a control plan of the driving system in accordance with reference information including first external environment information regarding an external environment of the moving body. The corrector is configured to execute, at a second timing between a plurality of first timings at each of which the update process is executed, a correction process of correcting the control plan in accordance with second external environment information regarding the external environment of the moving body. The second external environment information is different from the first external environment information. The controller is configured to control the driving system in accordance with the control plan.

Abstract: A rotation detecting device includes first and second magnetic detection elements that output first and second signals and a detection circuit having the first and second signals input thereto. The detection circuit includes an automatic correction circuit that performs generating and updating of a correction value for correcting the and second signals. The automatic correction circuit is configured to stop the generating or the updating of the correction value in at least one of a case where a rotation direction of an object is changed to a reverse rotation direction from a normal rotation direction and a case where a rotation direction of the object is changed to the normal rotation direction from the reverse rotation direction.

Abstract: A sensor includes a sensor element, a package accommodating the sensor element in an inside of the package, a grounding electrode disposed in the package, a lid covering an opening of the package, and a lead extending from the package. The lead includes first and second portions. The first portion of the lead is electrically connected to the grounding electrode and extends along a side surface of the package with a gap provided between the first portion and the side surface. The second portion of the lead is disposed between the lid and the package and extends toward the inside of the package. In this sensor, the opening can be sealed without soldering and reliably connect the lid to the grounding electrode.

Abstract: An inertial force sensor has a first sensor element, a second sensor element, a first signal processor, a second signal processor, and a power controller. The first sensor element converts a first inertial force to an electric signal, and the second sensor element converts a second inertial force to an electric signal. The first signal processor is connected to the first sensor element, and outputs a first inertial force value. The second signal processor is connected to the second sensor element, and outputs a second inertial force value. The power controller is connected to the first signal processor and the second signal processor, and changes power supplied to the second signal processor based on the first inertial force value.
