| 20090079438 | System and method for testing electrical connection - An electrical connection testing system for testing existence of an electrical connection between a first electronic device and a second electronic device. An electrostatic discharge (ESD) protection circuit is provided between the first and second electronic devices. The testing system includes a comparator having a first input connected to a power for output of the first electronic device and a second input connected to an output signal from the first electronic device. The output signal is adapted to be sent to the second electronic device through the ESD protection circuit. The testing system also includes a system for determining if a comparator output from the comparator is indicative of the first and second inputs being different or if the comparator output is indicative of the first and second inputs being substantially the same. | 03-26-2009 |
| 20090160778 | APPARATUS, METHOD AND COMPUTER PROGRAM PRODUCT FOR USING VARIABLE NUMBERS OF TACTILE INPUTS - An apparatus, method and computer program product are provided for using varying numbers of tactile inputs to manipulate different features of an electronic device. In particular, varying numbers of tactile inputs resulting from a user touching the electronic device touchscreen or touchpad may be used in order to adjust the speed of movement of an image displayed on the electronic device. Varying numbers of tactile inputs may likewise be used to adjust in various manners an adjustable feature represented by an icon displayed on the electronic device display screen. Finally, varying numbers of tactile inputs may further be used in order to unlock an electronic device in a secure, yet simple, manner. | 06-25-2009 |
| 20100123592 | Warning system for breaking touch screen or display - Disclosed herein are apparatus, method, and computer program whereby a signal generated by a touch screen device is received in response to a tactile input from a user on an input surface of the touch screen panel. In response, presenting information to a user, the information comprising a warning that the user is exerting an excessive amount of force on a surface of the touch screen panel. | 05-20-2010 |
| 20100265209 | POWER REDUCTION FOR TOUCH SCREENS - This specification relates to determining areas within touch screen, where a user input is possible. To reduce power consumption of a device with a touch screen, touch detection for sensing a user input is only activated within the determined areas, where a user input is possible. | 10-21-2010 |
| 20110069075 | METHOD AND APPARATUS FOR DISPLAYING ONE OR MORE PIXELS - In accordance with an example embodiment of the present invention, an apparatus comprising a data control line configured to comprise data for subsequent viewing on a display. Further, the apparatus comprises a refresh control line configured to update at least one pixel on a display; a frequency based selector coupled to the refresh control line; and a memory coupled to the frequency based selector and the data control line. The apparatus is configured to provide one or more signals to a pixel in a first mode of operation and a second mode of operation based at least in part on the refresh control line. | 03-24-2011 |

| 20080313382 | Method and Device for Mapping Signal Order at Multi-Line Bus Interfaces - The present invention provides methods and modules allowing for mapping of interface signals at for instance multi-line buses. A mapping of internal signal order schemes to external signal order schemes is enabled such that upon configuration any interface signals may carried on any lines of a multi-line bus. The configurability may obtained by the implementation of mapping logics and mapping algorithms, which associates external interface terminal to signal association to internal interface terminal to signal association in a configurable manner. | 12-18-2008 |
| 20090122795 | Method and apparatus for providing a shared message - According to some embodiments of the present invention provides a new and unique technique to extend a point-to-point communication with a point-to-multipoint feature. Each end node has, beside a unique address, a configurable address that can be updated via some configuration means from a control entity. The unique address is a dedicated address. Different end node can have the same configurable address. The sender of a message or packet must be aware of the used addresses in the system. The technique does not require any changes to the normal data communication protocol. The messages or packets are unchanged. The implementation is done on the sender side and in the end node. Each message or frame or packet contains only one address. Each message and packet is received by each end node. A message is used by an end node if the unique or configurable address is matching. Beside that there is a possibility that the filtering is done by a hub that is selecting the right end node according the port definition (each output port has a dedicated unique address and configurable address). Moreover, the shared image frame has been sent once by the sender, which results in lower power consumption and less load on the sender. | 05-14-2009 |
| 20090201259 | Cursor creation for touch screen - Quick cursor creation is obtained by providing touch detection information of at least one pixel cell to a source driver at the time when pixel information of the pixel cell is updated and updating pixel information of the pixel cell within a pixel output buffer depending on the touch detection information at the time when the pixel information is updated. | 08-13-2009 |
| 20100141272 | Read-out line - It is disclosed to measure the impedance of a read-out line. The read-out line includes at least two cascaded electrical circuit segments, each electrical circuit segment including two longitudinal arms, wherein one of the longitudinal arms includes an electrical component, and a lateral arm including a switch configured to close in the presence of an object in the vicinity of the switch. The measured impedance of the read-out line can be compared to a preset value corresponding to an allowable value of the impedance of the read-out line. | 06-10-2010 |
| 20100182286 | Integrated circuit protection layer used in a capacitive capacity - In one exemplary embodiment of the invention, an apparatus includes: at least one functional circuit; and an electrically-conductive protective layer on a protected surface of the apparatus, where the protective layer is arranged to be substantially opaque to incident light, where at least one portion of the protective layer is electrically isolated from a remainder of the protective layer, where the at least one portion is a plate of a capacitor for coupling at least one signal to said at least one functional circuit. | 07-22-2010 |
| 20110069015 | TOUCH DETECTION - An apparatus with a first and second touch screen, where the first touch screen has a plurality of first touch sensors formed as a first grid of rows and columns and the second touch screen has a plurality of second touch sensors formed as a second grid of rows and columns. A first processor detects touch areas by scanning through the first touch sensors in a predetermined order along the rows and columns. A second processor detects touch areas by scanning through the second touch sensors in a predetermined order along the rows and columns. A controller causes that the first and second processors scan the first and second grids synchronized such that when the first and second touch screens are arranged side by side, neighboring first and second touch sensors are scanned substantially simultaneously. | 03-24-2011 |
