Patent number: 9086738Abstract: An optical tracking device that is capable of operation on both glossy and diffuse surfaces includes at least one housing, at least one light source, and at least one sensor. The light source emits light toward a surface on which the housing is moved and the sensor receives the light emitted by the light source after it is reflected off of the surface. The light source is oriented such that the angle of incidence of the emitted light corresponds to Brewster's angle. The sensor may be also oriented such that the angle of reflection of the reflected light corresponds to Brewster's angle. The light emitted by the light source may be polarized to increase the p-polarization of the emitted light and/or the light received by the sensor may be filtered to block s-polarized portions of the reflected light.Type: GrantFiled: March 12, 2013Date of Patent: July 21, 2015Assignee: Apple Inc.Inventors: Omar Sze Leung, Matthew Last

Publication number: 20150109223Abstract: A haptic electromagnetic actuator for track pad is provided. The actuator includes an array of electromagnets with alternating South and North poles on a first end, each magnet comprising a metal core and an electrical wire around the metal core. The array of magnets is coupled to a base plate on a second end opposite to the first end. The actuator also includes an attraction plate at a distance from the first end of the array of the magnets such that the attraction plate moves toward the magnets when an electrical current flows through the electrical wire around the metal core and moves away from the magnets when the current becomes zero. The array of magnets is configured to form a uniform gap from the attraction plate.Type: ApplicationFiled: June 10, 2013Publication date: April 23, 2015Inventors: Patrick Kessler, Dhaval Chandrakant Patel, Jonah A.

Patent number: 8988396Abstract: One particular implementation conforming to aspects of the present disclosure takes the form of an input device for a computing system. The input device includes a input surface on which one or more input characters are shown and one or more sensors to detect which input character is pressed or selected by the user. In one example, the input device may include one or more piezo-electric sensors that detect an acoustic pulse created when the user taps on the input surface to indicate a selected input. Each character of the input surface of the input device creates a different acoustic pulse signature when tapped such that, upon detection and receiving of the acoustic pulse at the piezo-electric sensors, the input device or computer system may compare the received pulse to a database of stored pulse signatures to determine which character on the surface of the input device was tapped by the user.Type: GrantFiled: January 7, 2014Date of Patent: March 24, 2015Assignee: Apple Inc.Inventors: Mushtaq A. Sarwar, Omar Sze Leung, Aleksandar Pance, Brett Bilbrey, Andrew Ross Richardson

Publication number: 20140085253Abstract: A touch device including a force sensor disposed between capacitive sensing structures, so both touch and force sensing occur capacitively using device drivers in rows and columns. A dual-layer cover glass, with gel adhesive separating first and second CG layers, so capacitive sensing between the first and second CG layers can determine both touch locations and applied force. The first and second CG layers include a compressible material having a Poisson's ratio of less than approximately 0.48, the force sensor being embedded therein, or disposed between the first and second CG layers. Applied force is detected using capacitive detection of depression of the first CG layer. Depression is responsive to compressible features smaller than optical wavelengths, so those features are substantially invisible to users. Alternatively, the compressible features may be large enough to be seen by a user, but made substantially invisible through the use of a fluid or other element filling spaces between the features.Type: ApplicationFiled: November 14, 2012Publication date: March 27, 2014Applicant: Apple Inc.Inventors: Omar Sze Leung, Jonah A.

Publication number: 20140085213Abstract: A force sensor incorporated into a touch device, measuring deflection in a device stack, including compressible elements disposed between the device stack and the frame element. When the device stack is deformed, applied force is measured using the compressible elements, using capacitive sensing or strain measurements. The force sensitive sensor provides an applied force image for the touch device's surface. The applied force location [X, Y] can be determined from measures of cover glass tilt, force at particular points, and capacitive sensing of touch location.Type: ApplicationFiled: September 21, 2012Publication date: March 27, 2014Applicant: Apple Inc.Inventors: Brian Q.
