  • Publication number: 20200218377
    Abstract: Logic of a handheld controller can implement sensor fusion algorithms based on force data provided by a force sensing resistor (FSR) in combination with touch data or proximity data provided by a touch sensor or an array of proximity sensors, respectively. An example sensor fusion algorithm can be used to re-calibrate the FSR when an object contacts an associated control, as detected by the touch sensor. Another example sensor fusion algorithm can be used to ignore spurious inputs detected by the FSR when an object is in contact with an adjacent control. Another example sensor fusion algorithm can be used to detect a hand size of a hand grasping a handle of the controller, as detected by the array of proximity sensors, and to adjust the threshold force to register a FSR input event at the FSR according to the hand size.

  • Publication number: 20190139811
    Abstract: Semiconductor devices and methods of forming the same are provided. The methods may implanting dopants into a substrate to form a preliminary impurity region and heating the substrate to convert the preliminary impurity region into an impurity region. Heating the substrate may be performed at an ambient temperature of from about 800° C. to about 950° C. for from about 20 min to about 50 min. The method may also include forming first and second trenches in the impurity region to define an active tin and forming a first isolation layer and a second isolation layer in the first and second trenches, respectively. The first and second isolation layers may expose opposing sides of the active fin.

  • Publication number: 20060074320
    Abstract: In embodiments of the present invention, an ultrasound system includes an ultrasound machine, which may be located in a hospital, clinic, vehicle, home, etc., coupled to a remotely located diagnosis station via a communication network. For some embodiments, the ultrasound machine includes an application-specific scan head that has identification information that allows the home ultrasound machine to notify a user whether the attached scan head is appropriate for the type of examination to be performed. For other embodiments, a first stage of beamforming is conducted in reconfigurable hardware and a second stage of beamforming is conducted in programmable software digital signal processor.
