  • Patent number: 11893171
    Abstract: Computing systems and input devices can include a chassis with a computing device and an input tool with a sensor, such as a pen- or rod-like input tool, that can be positioned relative to the chassis in multiple configurations. In one configuration, the tool can be spaced away from the chassis and its sensor output can cause a first output signal in response to input provided to the sensor. In another configuration, the tool can be contacting the chassis and its sensor output can cause a second output signal in response to input provided to the sensor. For example, an input tool can be stowed in a recess of a keyboard housing or device chassis, and the input tool can produce a first output when it is in the recess and a second input when it has been removed from the chassis.

  • Patent number: 11886644
    Abstract: A human machine interface (HMI), a method of interacting with an HMI and a corresponding computer program product facilitate user interaction with an HMI. In a method, a face of a person attempting to interact with the HMI is detected and a gesture made by the person relative to the HMI is also detected. The method analyzes information regarding the face of the person that has been detected to determine whether the person is wearing personal protection equipment. In an instance in which the person is determined to not be wearing personal protection equipment, the method suspends a response to the gesture made by the person. However, in an instance in which the person is determined to be wearing personal protection equipment, the method analyzes the gesture made by the person relative to the HMI and converts the gesture to a corresponding command to the system associated with the HMI.
