  • Publication number: 20080211430
    Abstract: An electronic ballast system controls one or more ballasts of HID or fluorescent lamps, which are controlled in an “on/off” manner by a ultra low power controller that is isolated for a primary power circuit or derives its very low switch power from the ballast itself. The on/off control provides a near lossless control system. This system may be applied to electronic ballast for operates at fractional power levels corresponding to different lighting intensities and with conventional occupancy sensors. The system may also be applied to other electronically compatible end-use devices and applications.

  • Patent number: 7224131
    Abstract: A high efficiency lighting system maintains normal lighting conditions by lighting fixtures requiring DC electrical power. A power control device receives AC electrical power from a public utility converts AC power to DC power and delivers low voltage DC electrical power to lighting fixtures. A standby battery is provided to maintain power during power outages. Optionally, a photovoltaic DC electrical power source may be connected to the power control device, to provide alternate DC electrical power. In a further embodiment, a gas driven cogenerator unit may supply DC electrical power.

  • Publication number: 20070098152
    Abstract: Encryption and decryption of data stored from a computing system to a storage medium is disclosed wherein the processing employs a non-accessible encryption key that is unique to the computing system. The unique encryption key can be embedded in non-removable hardware of the computing system or generated, e.g., from identification numbers ascertained from non-removable hardware of the computing system. Processing includes establishing the unique encryption key, encrypting data using the unique encryption key and storing the encrypted data to the storage medium without storing the unique encryption key on the storage medium. The storage medium can comprise any non-removable or removable storage medium, including for example a computer hard drive, floppy diskette, or recordable compact disk.

  • Publication number: 20060107334
    Abstract: Embodiments of the present invention provide for flexible monitoring of content. The content at a client device can be monitored based on the use and actions performed by the client. In order to monitor the content at the client, a dependency is created between any recipient of the content and a monitor installed at the client device. For example, the content may be encrypted and, when the content is accessed by a potential recipient, the recipient may be required to request a key from the monitor. This activates the monitor to begin recording transaction data and events about the content's use, such as the recipient's identity and the type of actions performed. The monitor can be configured to passively monitor and record the use of the content at the client's device. In addition, the monitor can be configured to provide audit data that indicates the transaction data recorded to a server.

  • Publication number: 20060085343
    Abstract: A method, system and computer readable medium for the blocking of recording digital content at an end user multimedia end-user-system during the rendering of encrypted digital multimedia files. Before the process of rendering of encrypted digital multimedia can be started all rendered media stream during playback are opened to ensure that this multimedia content is not recorded. This blocks the usage of the multimedia interfaces including devices and/or ports that can be used to store un-encrypted content that has been decrypted for the purposes of playing or rendering. The method also includes an exception, which allows recording with permission from the present invention.

  • Publication number: 20050091656
    Abstract: A system and method for managing simultaneous access to a scarce or serially re-usable resource by multiple process threads. A stationary queue is provided, including a wait counter for counting the cumulative number of threads that have been temporarily denied the resource; a satisfied counter for counting the cumulative number of threads that have been denied access and subsequently granted access to said resource; a sleep code routine responsive to the wait counter for generating a run identifier; and a wakeup code routine responsive to the satisfied counter for generating the run identifier.

  • Patent number: 6614130
    Abstract: An electrical distribution system and method has storage battery mechanism of very large equivalent capacitance providing excellent ripple filtering and an ideal path to ground, and filter capacitor mechanism of microfarad size providing DC blocking and limited AC path to ground. The storage battery entity is maintained as to its charge by DC supply, which provides regulated DC power in which switching regulation may be involved. The system and method provides dual voltage capability, both DC and AC, in which circuit breakers may be ganged for simultaneous tripping, and in which intrinsic DC circuit(s) may be looped to increase current-carrying capability. A DC isolation capacitor is connected to a common current path, such as to one of the busses, such as, for example, in series with the neutral circuit, as a means for avoiding undesirable DC current paths as may be encountered due to a multitude of established neutral-line connections to earthing grounds established throughout in AC power supply network.

  • Patent number: 5969435
    Abstract: A DC power system receives AC electrical power and DC electrical power from separate first and second sources simultaneously. The DC power system delivers DC electrical power to an output for use by a load requiring DC power. The DC power system includes a converter to convert AC electrical power to DC electrical power and a power sharing control device to control and distribute the DC electrical power to an output. The first source of DC electrical power includes a storage battery, which provides standby DC electrical power to the DC power system. It also includes a power sharing device, which maintains the storage battery fully charged for use at peak loads, when the DC output electrical power is insufficient to meet the DC load.

  • Patent number: 5803754
    Abstract: An receptacle for low voltage DC applications includes a receptacle surface in which are located only one pair of female connections. One of the female connections is a terminal normally connected to the neutral line of an AC power grid, and the other of the female connections is a terminal connected to a ground line of an AC power grid. The two connections are arrayed to correspond with the neutral and positive terminals of a conventional three prong AC receptacle.
