20140281526 | Secure Network Storage - This invention includes apparatus, systems, and methods to secure data in a remote storage device where an end-point device does not have direct access to the storage device to secure the data, or the end-point device does not trust the storage device to adequately secure the data, comprising securing an authenticated communication between the end-point device and a synchronized storage server via a communication network. The synchronized storage server sends the end-point device a notification including the root folder list. The end-point device compares the sent root folder list to a previously stored root folder list in the end-point devices' memory. If the end-point device detects either a new root folder on the synchronized storage server, a change in an existing folder, or deleted content in a folder the end-point device will determine that a change is required to the stored data. Next the end-point device will synchronize with the synchronized storage server and create a new storage list. Finally, the synchronized storage server will send the end-point device a new encrypted folder encryption key which includes the encrypted file contents along with identifying information such as the server name and revision information. | 09-18-2014 |

20140253500 | Using Capacitive Proximity Detection with Resistive Touch Screens for Wake-Up - Power consumption of a device having a resistive touch screen may be reduced if the resistive touch screen is not scanned unless a touch thereto is imminent, especially if the device can remain in a low power sleep mode during no-touch inactivity. Furthermore, detecting a potential touch earlier then an actual first touch may improve initial touch response time.

The top ITO coated plane may be used as a capacitive proximity detector and the bottom ITO coated plane may be used as a guard shield for the top ITO coated plane to significantly reduce parasitic capacitance thereof and enhance the sensitivity of capacitive proximity detection. The device may also remain in a low power sleep mode until a potential touch is detected thereby further saving device power consumption. | 09-11-2014 |
20140267152 | Force Sensing X-Y Touch Sensor - A force sensing X-Y touch sensor comprising a plurality of conductive electrode rows, a plurality of electrode columns substantially perpendicular to and over the plurality of conductive electrode rows, a flexible electrically conductive cover over the electrode columns and a plurality of deformable spacers between the cover and the electrode columns, wherein the deformable spacers maintains a distance between the cover and the electrode columns.
