  • Patent number: 11499292
    Abstract: In embodiments, a work vehicle magnetorheological fluid (MRF) joystick system includes a joystick device, an MRF joystick resistance mechanism, and a controller architecture. The joystick device includes, in turn, a base housing, a joystick, and a joystick position sensor. The MRF joystick resistance mechanism is controllable to selectively resist movement of the joystick relative to the base housing. The controller architecture is configured to: (i) when detecting operator rotation of the joystick in an operator input direction, determine whether continued joystick rotation in the operator input direction will misposition the work vehicle in a manner increasing at least one of work vehicle instability and a likelihood of work vehicle collision; and (ii) when determining that continued joystick rotation will misposition the work vehicle, command the MRF joystick resistance mechanism to generate an MRF resistance force deterring continued joystick rotation in the operator input direction.

  • Patent number: 10741189
    Abstract: Embodiments that generate multiple haptic effects receive a first haptic effect signal having a first priority and corresponding to a first haptic effect, and receive a second haptic effect signal having a second priority and corresponding to a second haptic effect. When the first priority is less than the second priority, embodiments generate an interaction parameter using the second haptic effect signal. When the second priority is less than the first priority, embodiments generate the interaction parameter using the first haptic effect signal. Embodiments then apply a drive signal to a haptic output device according to the interaction parameter, where the drive signal causes the first haptic effect and the second haptic effect to be generated by the haptic output device concurrently.

  • Patent number: 10712931
    Abstract: A user may provide finger press input to a surface such as a touch sensitive input surface. The input surface may be formed from a two-dimensional touch sensor overlapping a display of an electronic device. The electronic device and an associated device such as a finger-mounted device may form a system for gathering the finger press input from the user. A sensor may be used in monitoring when the finger-mounted device and a user's finger in the device approach the input surface of the electronic device. In response to detection of the finger near the input surface, actuators in the finger-mounted device may squeeze the finger inwardly to cause a finger pad on the finger to protrude outwardly towards the input surface, thereby softening impact between the finger and the input surface. The electronic device may also have an array of components to repel the finger-mounted device.

  • Patent number: 10693518
    Abstract: A device and method of verifying protective case usage, is described. The device includes one or more processors to drive an electromechanical transducer with an input signal. The electromechanical transducer generates an input force based on the input signal, and a sensor of the device generates a test output signal in response to the input force. The one or more processors determine, based on the test output signal, a level of verification that a protective case is mounted on the device. The determination can include determining whether the test output signal matches a predetermined impulse response signal indicative of an unprotected device or a protected device. A digital identification tag of the protective case can be read by a radio-frequency transceiver of the device to provide an additional level of verification that the protective case is mounted on the device. Other aspects are described and claimed.
