Patent number: 11429205Abstract: A stylus having an applied force-sensitive tip-switch is disclosed. The stylus includes a tip-switch responsive to a variable applied force. Control circuitry determines whether the tip-switch has made contact with an object and, if so, the magnitude of the applied force resulting from the contact. The circuitry then encodes a signal that varies with the magnitude of the applied force and transmits the encoded signal to a computing device, enabling the computing device to indicate the two- or three-dimensional path of the tip-switch in the stylus on a computer screen. The circuitry also monitors a manual override switch that activates an encoded override signal for interpretation and use by the computing device while indicating the path of the tip switch on a computer screen.Type: GrantFiled: July 31, 2014Date of Patent: August 30, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: David Bradley Short, Jinman Kang, Ben Wynne, Jamie Etcheson
