Abstract: A lamp driver circuit to selectively energize one or more lamps is provided. The inverter circuit has a transformer with primary and secondary windings to provide voltage to the lamps. A filter is connected to the primary winding to receive a primary winding signal representative of the voltage across the primary winding. The primary winding signal has a frequency spectrum and the filter detects a particular characteristic of the frequency spectrum that is indicative of an end of life (EOL) condition of the one or more lamps. A control circuit is connected to the inverter circuit and to the filter. The control circuit is configured to discontinue energizing of the one or more lamps by the inverter circuit when the particular characteristic of the frequency spectrum of the primary winding signal is detected by the filter.

Abstract: A ballast for driving one or more lamps includes a controller and a current reduction circuit for accelerating a controller reset. Upon detecting a fault, the controller disables the ballast for a preset period of time, and resets. The controller additionally resets when the ratio of a supplied second value to a supplied first value falls below a threshold value. The current reduction circuit reduces the supplied second value in less than the preset period of time, such that the ratio falls below the threshold value and the controller resets. An emergency lighting system includes the ballast as a primary ballast, a backup ballast, and a primary power source. The controller detects a fault if the primary power source de-energizes and the backup ballast disconnects the one or more lamps from the primary ballast. The current reduction circuit accelerates the reset of the controller when the primary power source de-energizes.

Abstract: Resistive switching memory elements are provided that may contain electroless metal electrodes and metal oxides formed from electroless metal. The resistive switching memory elements may exhibit bistability and may be used in high-density multi-layer memory integrated circuits. Electroless conductive materials such as nickel-based materials may be selectively deposited on a conductor on a silicon wafer or other suitable substrate. The electroless conductive materials can be oxidized to form a metal oxide for a resistive switching memory element. Multiple layers of conductive materials can be deposited each of which has a different oxidation rate. The differential oxidization rates of the conductive layers can be exploited to ensure that metal oxide layers of desired thicknesses are formed during fabrication.

Abstract: Nonvolatile memory elements are provided that have resistive switching metal oxides. The nonvolatile memory elements may be formed by depositing a metal-containing material on a silicon-containing material. The metal-containing material may be oxidized to form a resistive-switching metal oxide. The silicon in the silicon-containing material reacts with the metal in the metal-containing material when heat is applied. This forms a metal silicide lower electrode for the nonvolatile memory element. An upper electrode may be deposited on top of the metal oxide. Because the silicon in the silicon-containing layer reacts with some of the metal in the metal-containing layer, the resistive-switching metal oxide that is formed is metal deficient when compared to a stoichiometric metal oxide formed from the same metal.

Abstract: A ballast for dimming a lamp is provided. The ballast includes an inverter circuit for providing a lamp current for energizing the lamp and a dim interface for receiving an input indicative of a selected lighting level. A control circuit is connected to the dim interface for generating a pulse-width-modulated signal having a duty cycle corresponding to the selected lighting level. A switching network is connected to the control circuit for receiving the pulse-width-modulated signal. The switching network operates between a conductive state and a non-conductive state as a function of the pulse-width-modulated signal. An impedance device is connected across the switching network and is configured for connecting in series with the lamp so that the impedance device receives the lamp current when the switching network is operating in the non-conductive state and the lamp current bypasses the capacitor when the switching network is operating in the conductive state.
