  • Patent number: 11125282
    Abstract: A torque limiting assembly is disclosed comprising: an input shaft; an output shaft; and spring having a first end coupled to the input shaft and a second end coupled with the output shaft. In a low torque mode, when the input shaft is rotated the spring is compressed by a low amount and transmits a force to drive rotation of the output shaft, whereas in a high torque mode the spring is compressed by a high amount such that the input shaft rotates relative to the output shaft. This relative rotation moves or urges an engagement member so as to either: disconnect the input shaft from the output shaft; or engage a housing to prevent or inhibit rotation of the input shaft relative to the housing.

  • Patent number: 11117686
    Abstract: Providing collision avoidance protection to controllers sharing the same sensor. Each of a pair of asynchronous controllers changes the period of a sync pulse transmitted to the other controller to indicate to the other controller it is synchronized. When one of the controllers begins reading data from the shared sensor, the other controller waits to receive another sync pulse for indicating when the controller is finished reading data from the shared sensor. Thus, the asynchronous controllers avoid accessing the same sensor at the same time.
