Patent number: 9780781Abstract: A multi-action capacitive switch comprising a capacitive sensing area in a surface, a plunger comprising conductive material, and a structure of flexible conductive material. A change in capacitance caused by the presence of a user's finger travels from the capacitive sensing area, down the conductive material of the plunger, over the structure, and to a capacitive touch detector in contact with the structure. An actuation of the switch, for example by pressing, is detected by an actuation detector. In a handheld electronic device, a user may initiate a phone call using such a multi-action capacitive switch. The method includes displaying a list of phone numbers in response to detection of a user's finger on a predetermined key and calling one of the numbers when the user actuates the predetermined key.Type: GrantFiled: September 28, 2010Date of Patent: October 3, 2017Assignee: BlackBerry LimitedInventors: Yun Sun Lee, Chin Feng Hsu

Patent number: 8384689Abstract: A switched-capacitor tracking apparatus including a variable capacitor, an auxiliary capacitor, and a plurality of switches, and an operating method thereof are provided. In a charge period, a first reference voltage charges a panel capacitor, and a second reference voltage charges the variable capacitor.
