A method of fabrication and use are provided. | 01-31-2013 |
20130029215 | Aluminum housing with a hermetic seal - A housing for an energy storage cell includes an interior which provides beneficial properties to fabricators of the cell. The cell may be hermetically sealed by conventional laser welding techniques. | 01-31-2013 |
20130141088 | NON-INTRUSIVE MONITORING OF POWER AND OTHER PARAMETERS - Methods and apparatus for non-intrusive power monitoring and current measurement in a circuit breaker without modification of the breaker panel or the circuit breaker itself. In one example, an inductive pickup sensor senses current from the breaker face, an inductive link transmits power through a steel breaker panel door, and a passive balanced JFET modulator circuit modulates a carrier signal on the inductive link with information regarding the sensed current. A demodulated breaker current signal is available outside of the breaker panel door. The JFET modulator circuit does not require DC power to modulate the carrier signal with the information regarding the sensed current from the breaker. Such methods and apparatus may be interfaced with a spectral envelope load detection system that can monitor multiple loads from a central location. | 06-06-2013 |
20130141840 | ON-BOARD POWER SUPPLY - A power supply for a device disposed on a substrate is provided. An electrolytic double layer capacitor disposed in a circuit to provide power to circuit components is described. Aspects of fabrication are provided. | 06-06-2013 |
