  • Patent number: 11567575
    Abstract: Haptic response is controlled in a device having a touch sensor, a force sensor, and a haptic response actuator operably coupled to a touch surface. A user touch to the touch surface is detected by the touch sensor. A force applied to the touch surface is sensed by the detected user touch. Electrical power supplied to the haptic response actuator is adjusted based at least in part on the sensed force satisfying a haptic condition. The haptic response to the touch surface is actuated based at least in part on satisfaction of the haptic condition and the supply of the adjusted electrical power to the haptic response actuator.

  • Patent number: 7253384
    Abstract: An apparatus comprising a movable optical element having an optical axis and including one or more focusing elements, an image sensor positioned along the optical axis and substantially normal thereto, and a radiation source attached to the movable optical element, wherein the radiation source directs a beam of radiation onto the sensor at a selected angle relative to the optical axis. A process comprising positioning a sensor along, and normal to, an optical axis of a movable optical element, projecting a radiation beam onto the sensor from a radiation source attached to the movable optical element, wherein the radiation beam is at a selected angle relative to the optical axis, and adjusting the position of the movable optical element until the position where the radiation beam falls on the sensor corresponds to the position where the radiation beam is expected to fall on the sensor when the movable optical element is in focus. Other embodiments are disclosed and claimed.
