Abstract: A method for generating and maintaining hierarchical tags with community-based ratings is provided. Tags for media streams are organized into a hierarchical format. Users may select tags from the hierarchical tag database that describes a particular multimedia content. If the user is unable to locate a desired tag, the user may submit a new tag. Upon submission of the new tag, a librarian approves the tag before storing and placing the tag in the hierarchical tag database. Users are also able to rate the quality of the association between the tag and the multimedia content. If a tag is rated low, the tag may be removed from the hierarchical tag database. If the tag is rated highly, display of the tag in a list of tags becomes more prominent.

Abstract: Techniques for identifying a trusted SSID for a wireless network are disclosed. Prior to establishing a connection with a wireless network, a first network message is received from a first access point (AP) identifying a first service set identifier (SSID) associated with a first wireless network, a second network message is received from a second AP identifying a second SSID associated with a second wireless network, and a visual similarity is determined between a first visual representation of the first SSID and a second visual representation of the second SSID. The second SSID is designated as suspicious based on the determined visual similarity.

Abstract: A method and arrangement for transferring data between nodes over a telephone cable that couples the nodes provides a dual configuration node transmitter, and a dual configuration node receiver. The dual configuration transmitter has a first transmitter circuit that transmits data over a first configuration of the telephone cable and a second transmitter that simultaneously transmits other data over a second configuration of the telephone cable. The dual configuration receiver is coupled to the telephone cable and has a first receiver circuit that selects the data transmitted by the first transmitter circuit and rejects the data transmitted by the second transmitter circuit, and a second receiver circuit that selects the data transmitted by the second transmitter circuit and rejects the data transmitted by the first transmitter circuit.

Abstract: Miniature light-activated lamp control apparatus and the like, including a thin disk-shaped switching unit positionable within a light bulb socket and a thin light conductor having one end attached thereto, the light conductor being extendable through the gap between the electrically conductive inner wall of the socket and the electrically conductive outer surface of the bulb base disposed in the socket, and terminating at the opposite end in a lens for gathering ambient or other light. The switching unit has a first contact on one side for engagement with the socket center terminal, and a second contact on an opposing side for engagement with the center terminal of a light bulb. The unit includes a thin circuit board having control circuitry mounted thereon, such circuitry being positioned to occupy available space between the conical bulb base and the circuit board.

Abstract: A switch for reacting quickly to a neutron emission. A rod consisting of fissionable material is located inside a vacuum tight body. An adjustable contact is located coaxially at an adjustable distance from one end of the rod. Electrical leads are connected to the rod and to the adjustable contact. With a vacuum drawn inside the body, a neutron bombardment striking the rod causes it to heat and expand longitudinally until it comes into contact with the adjustable contact. This circuit closing occurs within a period of a few microseconds.

Abstract: Data is stored on a rotating memory disk by maintaining constant the relative velocity between the recording transducer and the recording media. The rotational speed of the disk is varied as the transducer is translated radially of the disk recording surface, the disk surface being divided into a number of concentric track zones each containing a predetermined number of tracks. For any given zone, an optimum rotational motor speed is established and the rotational speed of the disk is maintained at that zone speed when the transducer position signals specify a given zone. As the transducer is commanded to step to a different track in a different zone, the rotational speed of the disk is altered to match the new zone speed within a relatively short period of time. Once the transducer is located within the given zone, the rotational disk speed is maintained at that zone speed for motion within the zone.
