摘要:
Systems and methods are provided for deriving power for an external device from the power source of a fluorescent light. The power source includes a fluorescent ballast electrically connected to the connectors of a light fixture for receiving an input voltage and for converting the input voltage to a lamp voltage suitable for powering a fluorescent lamp. The fluorescent ballast may be modified to include an output line that outputs a voltage for powering the external device to a power port. The power port may be mounted on or near the fluorescent light. Alternatively, the power port may be integrated within a housing that contains one of the connectors of the light fixture. The ballast may be further modified to include an output line for extracting network data and control signals from the power line carrier signals on the input voltage.

Systems and methods are provided for deriving power for an external device from a circuit of a fluorescent light. A first circuit supplies power from a fluorescent light power source to a fluorescent lamp. The power converter of an external device can be electrically connected to any two points within that circuit to create a second circuit to supply power to the external device. The power converter may be connected to the first circuit via one or more power coupling or power tether. At least one of the two points within the first circuit may comprise a pin of the fluorescent lamp. Alternatively, at least one of the two points may comprise a connector of a fluorescent light fixture designed to receive a pin of the fluorescent lamp or a point within the fluorescent ballast of the fluorescent light fixture.

Methods and Apparatus are provided for a power supply capable of being operated directly from fluorescent lighting fixture and capable to functioning properly when supplied by conventional 60 cycles per second (cps) “Core and Coil’ fluorescent lamp power supply (ballasts) as well as ‘Electronic’ or ‘Solid State’ ballasts functioning at frequencies from 20,000 cps to as much as 40,000 cps, without adversely affecting normal lighting fixture operation.

A mobile subscriber can elect to grant permission for the release to a requesting party of information relevant to the mobile subscriber release information. In the alternative, the mobile subscriber can elect to establish a communications path directly with the requesting party. The mobile subscriber can initiate this communications path without divulging their identity or contact information to the requesting party. For example, the mobile subscriber can elect to block a display of their identity and calling information to the requesting party by the use of identity blocking codes or blocking methods that hide this information.
摘要:
A system for communicating with the user of a cellular telephone via the cellular mobile radio (CMR) system and the public switched telephone network (PSTN). A communications interface appends the telephone exchange number of an outgoing communication to include an identifier unique to the communications interface. The outgoing communication is transmitted by the cellular telephone to the CMR system, which recognizes and verifies the outgoing communication as originating with the communications interface. Accordingly, the origination of the outgoing communication from a communications interface is documented prior to forwarding the outgoing communication to its intended recipient via the PSTN. Communications incoming to a communications interface are authenticated as such, and a record as to this is created, prior to forwarding the incoming communication to the cellular telephone.

The invention provides methods and apparatuses covering subscriber initiated handoff to improve call quality, change networks, record a quality event, or for other purposes. The subscriber initiated handoff is primarily designed to be used in conjunction with a wireless network.

A grant of permission is operative to release the personal information of a user, such as mobile subscriber of a mobile telephone network, prior to transmitting that information to a requesting party. If the permission grant is delayed, however, the delivery of the mobile subscriber's information can be provided at a later time to the requesting party if the mobile subscriber subsequently grants permission. The requesting party can receive information relevant to the mobile subscriber via text message, e-mail, or other conventional media in response to the delayed permission grant. The mobile subscriber can grant a delayed release of the information or contact the requesting party directly without revealing the requested information.
摘要:
A mobile subscriber can elect to grant permission for the release to a requesting party of information relevant to the mobile subscriber release information. In order to make the decision to provide the information to the requesting party, the mobile subscriber can first determine if the request is being made from a trusted source. If the identity of the requesting party is hidden, the requesting party can be queried to release their identity to be used in conjunction with the permission request to the mobile subscriber.
摘要:
Confirmation of a mobile subscriber's permission to release their personal information is completed prior to transmitting the information to a requesting party. The mobile subscriber can view the requesting party's identity prior to making a decision to release their directory information. In the alternative, the mobile subscriber can contact the requesting party directly without a release of their personal information. Other types of information, such as location information, can also be communicated to a requesting party by this permission grant methodology.
