  • Publication number: 20190248438
    Abstract: A wireless receiving device for a human powered vehicle comprises a receiver having a first mode, and a second mode in which the receiver consumes less electric power than in the first mode. A controller is configured to set the receiver with the second mode if the receiver does not receive the communication signal in a first-mode period during which the receiver operates in the first mode. The controller is configured to count a consecutive number of a plurality of no-communication periods if no-communication periods consecutively occur. The controller is configured to set the receiver with the first mode if the consecutive number of the no-communication periods is less than a count threshold. The controller is configured to control the receiver to continue the second mode until a release condition is satisfied if the consecutive number is more than or equal to the count threshold.

  • Patent number: 10372267
    Abstract: A force detection apparatus includes: a force detector that includes an electrode and a conductor facing the electrode across a first and a second layers and outputs a force signal value before correction; and a force detection controller outputting a force signal value after correction having a linear relationship with a force. In a first range of force in which the first layer is deformed and the second layer is not deformed, the force detection controller calculates the force signal value after correction, based on a product of the force and a first constant. In a second range of force in which the first and second layers are deformed, the force detection controller calculates the force signal value after correction, based on a sum of a product of a threshold and the first constant and a product of a difference between the force and the threshold and a second constant.
