Patent number: 10908742Abstract: A device is provided. The device comprises a conductive element comprising one or more grooves, a capacitive field measurement element coupled to the conductive element, and a controller coupled to the capacitive field measurement element. The grooves comprise material with conductivity lower than the conductivity of the conductive element. The capacitive field measurement element is configured to measure change in the capacitive field in proximity of the grooves caused by physical interaction or proximity between the grooves and an external object, and provide the measurement to the controller. The controller is configured to trigger at least one function assigned to the one or more grooves when a change in the capacitive field in proximity of the one or more grooves is measured. Methods of operation and manufacture are also presented.Type: GrantFiled: October 21, 2015Date of Patent: February 2, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Jari Saukko, Joni Arola, Pertti Husu

Patent number: 10754478Abstract: A device is described. In an example, a device comprises a capacitance sensor layer and a conductive grounded layer. The conductive grounded layer is placed under the capacitance sensor layer in a direction opposite to a targeted sensing direction of the device. The distance between the capacitance sensor layer and the conductive grounded layer is configured to remain within a threshold over a range of deformation. In other examples, a method for manufacturing a device and a module are discussed along with the features of the device.Type: GrantFiled: May 3, 2017Date of Patent: August 25, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Marko K.

Patent number: 10528172Abstract: Technologies are described for pressure sensors used in display devices. In one embodiment, a reference ground layer and sensing pad can be positioned between a display substrate and a window substrate. Additionally, a compression region can be positioned between the display substrate and the window substrate. The compression region can be compressed so as to change a distance between the reference ground layer and the sensing pad. By placing the compression region between the window substrate and the display substrate, the air gap below the display substrate can be removed. In still another embodiment, the sensing pad is aligned over a frit layer, but it is divided into spaced-apart sub-regions that are serially coupled together. Gaps between the sub-regions are sized such that the laser can adequately penetrate through the sensor pad to melt the frit.Type: GrantFiled: June 17, 2016Date of Patent: January 7, 2020Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Joni Arola, Marko Heikkinen

Publication number: 20180039365Abstract: A sensor and a method for detecting a displacement are disclosed with one implementation having a force sensor on a display. The sensor reacts to a bend of a conductor, wherein a diameter of the bends corresponds to a self-capacitance that is measurable from the conductor. In one embodiment the bent conductor is placed between two circuit boards or between a circuit board and a display, wherein a force applied to either surface causes a change in the bend diameter and the force may be measured. The sensor may be digital with a processor or analog with discrete components.Type: ApplicationFiled: August 2, 2016Publication date: February 8, 2018Inventors: Joni Arola, Hiroshi Sasaki

Publication number: 20170371441Abstract: Techniques are described for pressure sensors used in display devices. In one embodiment, a capacitive shielding layer is used to block capacitive effects of user input from reaching sensor pads of the pressure sensor. In this way, the pressure sensor can extend into an active area of the display traditionally reserved for only touch sensors. The capacitive shielding layer can have gaps therein for allowing capacitive effects of touch input signals to pass to the touch sensors, while blocking the input signals from the pressure sensor. To reduce visibility of the pressure sensor in the active area, traces from both the pressure sensor and the capacitive shielding layer can be angled with respect to an edge of the display.Type: ApplicationFiled: June 22, 2016Publication date: December 28, 2017Applicant: Microsoft Technology Licensing, LLCInventors: Marko Heikkinen, Joni Arola

Patent number: 9835769Abstract: A method which may be used for forming an optical effect coating for a light transmission element configured to form a part of a cover of a device is disclosed. The method comprises: printing a first coating layer having a plurality of adjacent first elongated micro openings extending in a first direction in an aperture area, and printing a second coating layer having a plurality of adjacent second elongated micro openings extending in a second direction, the second direction differing from the first direction, in the aperture area. Thereby, an optical effect coating is formed, comprising micro holes formed at intersections of the first and the second elongated micro openings, the micro holes producing locally increased effective light transmittance through the optical effect coating in the aperture area.Type: GrantFiled: May 4, 2015Date of Patent: December 5, 2017Assignee: Microsoft Technology Licensing LLCInventors: Hiroshi Sasaki, Joni Arola
