| 20110005066 | Method Of Forming A Photovoltaic Cell Module - A method of forming a photovoltaic cell module uses a cell press having a table and a plate that is spaced from and moveable relative to the table. The method includes supporting the cell with the plate between the plate and the table. A substrate and a tie layer disposed on the substrate are introduced between the cell and the table with the substrate supported by the table and with the tie layer facing the cell. One of the cell and the table are moved toward the other until the cell contacts the tie layer. A vacuum is applied between the cell and the tie layer to evacuate the space between the cell and the tie layer as the cell contacts the tie layer. This evacuation eliminates the possibility of air bubbles being formed between the cell and the tie layer as the cell contacts the tie layer. | 01-13-2011 |

| 20110200194 | AMBULATORY REPEATER FOR USE IN AUTOMATED PATIENT CARE - An ambulatory repeater for use in automated patient care is presented. A local memory store includes a cryptographic key, sensitive information, and physiological measures. The cryptographic key is uniquely assigned to the implantable medical device prior to implant of the implantable medical device into a patient. The sensitive information is preencrypted under the cryptographic key and physiological measures are measured by the implantable medical device. An authentication module is in receipt of the cryptographic key. A permissions module confirms authorization of an external data processing device against the cryptographic key. A decryption module decrypts the sensitive information with the cryptographic key into decrypted information. A processor is operatively coupled to the local memory store. A communications module exchanges the decrypted information and the physiological measures with the external data processing device over a wireless interface contingent upon the authorization confirmation. An internal power supply supplies power to the foregoing components. | 08-18-2011 |

| 20100156913 | Multi-display handheld device and supporting system - Current approaches to paperless books use single screen laptop computers or electronic paper display (EPD)-based book readers. Laptop computers consume too much power and cannot be used for extended periods of time, such as an entire school day, without recharging its battery. EPD devices are limited in functionality due to their slow refresh rate and grey-scale only images. An embodiment of the present invention integrates bi-stable display technology and refresh display technology into a single device and manages the use of these technologies to achieve power savings while providing a rich set of display functionalities to support user interaction with content in a synergistic manner. The power savings functionality enables the device to have a battery operating life between charges of many hours of operation, such as eight hours or more, while the display functionality enables users to access, display, and interact with content in ways users have become accustomed and in ways not before possible. | 06-24-2010 |
