Patent number: 6661410Abstract: Capacitive proximity sensing is carried out by detecting a relative change in the capacitance of a “scoop” capacitor formed by a conductor and a surrounding ground plane. The conductor may be a plate provided in the form of an adhesive label printed with conductive ink. Charge is transferred between the “scoop” capacitor and a relatively large “bucket” capacitor, and a voltage of the bucket capacitor is applied to an input threshold switch. A state transition (e.g., from low to high, or high to low) of the input threshold switch is detected and a value (TouchVal) indicative of a number of cycles of charge transfer required to reach the state transition is determined. The presence or absence of an object or body portion in close proximity to or contact with a device can be determined by comparing TouchVal with a predetermined threshold value (TouchOff).Type: GrantFiled: September 7, 2001Date of Patent: December 9, 2003Assignee: Microsoft CorporationInventors: Mark W. Casebolt, Gary Rensberger, Steven N. Bathiche, Mihai Abulet

Patent number: RE46025Abstract: To reduce viewing angle dependence of ? characteristics in a normally black liquid crystal display. Each pixel 10 has a first sub-pixel 10a and a second sub-pixel 10b which can apply mutually different voltages to their respective liquid crystal layers. Relationships ?V12 (gk)>0 volts and ?V12 (gk)??V12 (gk+1) are satisfied at least in a range 0<gk?n?1 if it is assumed that ?V12=V1?V2, where ?V12 is the difference between root-mean-square voltage V1 applied to the liquid crystal layer of the first sub-pixel 10a and root-mean-square voltage V2 applied to the liquid crystal layer of the second sub-pixel 10b.Type: GrantFiled: October 15, 2009Date of Patent: June 7, 2016Assignee: SHARP KABUSHIKI KAISHAInventor: Fumikazu Shimoshikiryo

Patent number: RE46058Abstract: An electrode structure is disclosed for enhancing the brightness and/or efficiency of an LED. The electrode structure can have a metal electrode and an optically transmissive thick dielectric material formed intermediate the electrode and a light emitting semiconductor material. The electrode and the thick dielectric cooperate to reflect light from the semiconductor material back into the semiconductor so as to enhance the likelihood of the light ultimately being transmitted from the semiconductor material. Such LED can have enhanced utility and can be suitable for uses such as general illumination. The semiconductor material can have a cutout formed therein and a portion of the electrode can be formed outside of the cutout and a portion of the electrode can be formed inside of the cutout. The portion of the electrode outside the cutout can be electrically isolated from the semiconductor material by the dielectric material.Type: GrantFiled: December 16, 2013Date of Patent: July 5, 2016Assignee: Kabushiki Kaisha ToshibaInventor: Frank T.
