Publication number: 20090188727Abstract: An apparatus with multiple processing units is provided for processing signals from one or more electromagnetic antenna board in a concurrent and/or cooperative manner. The apparatus of the present invention includes a plurality of signal processing units, each connected to a different or same electromagnetic antenna board, and an integration processing unit connected to each of the signal processing units. The signal processing units process the signal from the connected antenna board independently, if connected to different antenna board, or cooperatively, if connected to the same antenna board. The result of the processed signals are then fed to the integration processing unit, which will perform further processing to obtain the final output signals.Type: ApplicationFiled: January 24, 2008Publication date: July 30, 2009Inventor: Yun-Hsiang Yeh

Patent number: 7474300Abstract: In a position detecting apparatus, electric power of a position pointer is turned on only when the position pointer is put within a particular range from a tablet to minimize consumption of a battery disposed in the position pointer. When the position pointer is brought close to the tablet, a control signal transmitted from the tablet is detected by a resonant circuit of the position pointer, and MOSFETs serving as a power switch are turned on by the detected signal. In response, electric power is supplied from a battery via the MOSFETs to circuit elements of the position pointer, and thus an operation of the position pointer starts.Type: GrantFiled: November 12, 2004Date of Patent: January 6, 2009Assignee: Wacom Co., Ltd.Inventors: Yuji Katsurahira, Sadao Yamamoto

Patent number: 7327354Abstract: A method of determining a type of touch plane operator input device comprises sensing the impedance across first and second terminals of a touch plane operator input device to distinguish the touch plane operator input device as being one of at least two different types of touch plane operator input devices. A method of processing an input from a touch plane operator input device comprises determining a first location of a first touch on the touch plane operator input device; determining a second location of a second touch on the touch plane operator input device; comparing the first and second locations to obtain an indication of an amount of difference between the first and second locations; and determining whether the indication of the amount of difference exceeds a predetermined amount. These steps are performed by discrete logic circuitry that provides an event notification to a microprocessor when the indication of the amount of difference exceeds the predetermined amount.Type: GrantFiled: April 27, 2004Date of Patent: February 5, 2008Assignee: Rockwell Automation Technologies, Inc.Inventor: Gary Dan Dotson

Patent number: 7176902Abstract: Bending wave vibrations propagating in a substrate of a touch input device are sensed. Provision is made for discriminating between sensed vibrations propagating in the substrate indicative of an intended touch and sensed vibrations propagating in the substrate indicative of an unintended touch. In response to the sensed vibrations propagating in the substrate indicative of the intended touch, a wake-up signal is generated. The wake-up signal is communicated to a control system of the touch input device for transitioning the control system from a sleep state to an operational state.Type: GrantFiled: October 10, 2003Date of Patent: February 13, 2007Assignee: 3M Innovative Properties CompanyInventors: Richard A.
