| 20080261107 | ROBUST METAL FILM ENCAPSULATION - The present invention relates to metal film encapsulation of an electrochemical device. The metal film encapsulation may provide contact tabs for the electrochemical device. The present invention may also include a selectively conductive bonding layer between a contact and a cell structure. The present invention may further include ways of providing heat and pressure resilience to the bonding layer and improving the robustness of the protection for the cell structure. | 10-23-2008 |
| 20090251099 | Passive over/under voltage control and protection for energy storage devices associated with energy harvesting - Described herein is, for example, a battery or capacitor over voltage (overcharge) and under-voltage protection circuit, that, for example, is adapted to not draw current from the battery or capacitor to be charged unless charge energy is detected and to not charge an energy storage device when an over-charge condition is sensed. The protection circuit may, for example, not be turned on unless an over voltage condition is present. Incoming energy to the system can be shunted to ground via a shunt load of various types including resistive loads and active components such as a zener diode. In some embodiments, no switching of the inbound power is required. Within limits, no regulation of inbound power is needed. When inbound power is sufficient to charge the battery or capacitor, regulation can occur via the applied shunt regulator if overcharge voltage conditions exist. Either type of charge source, voltage or current, can be used to provide charge energy. Combining said battery or capacitor over voltage (overcharge) and under-voltage protection circuit with electronic loads, such as wireless sensors, may lead to autonomously-powered wireless sensor systems. | 10-08-2009 |
| 20100032001 | Energy Device With Integral Collector Surface For Electromagnetic Energy Harvesting And Method Thereof - An apparatus, method, and system to harvest and store electromagnetic energy is disclosed. The present invention uses, for example, conductive surfaces within the energy storage component itself as a means of electromagnetic energy collection. The surface may be an integral portion of the energy device, such as a charge collection surface within a battery or a capacitor that mainly provides the battery or a capacitor with a necessary function. In another embodiment of the invention a metallic or conductive surface is added to and specifically built into the energy device during manufacturing for the main purpose of collecting electromagnetic energy for the energy device but is otherwise not necessary for the energy storage component. Once the energy is collected, it can be rectified either via rectification components that were built directly into the energy storage component during its manufacture or connected external to the energy storage component but within the energy device. The so-designed energy device may represent a self-sustaining, autonomous electromagnetic energy harvesting—energy storage device. | 02-11-2010 |

| 20100294428 | Method of Integrating Electrochemical Devices Into and Onto Fixtures - Methods of integrating an electrochemical device to a fixture are disclosed. When performed, these methods may, for example, result in the improved performance and/or extended shelf life of the electrochemical device. These methods may include, for example, discharging an electrochemical device prior to an integration process, limiting the temperature exposure of the electrochemical device during the integration process, and/or applying a constraining force to a surface of the electrochemical device during an integration process. | 11-25-2010 |
