Abstract:
The present invention is an applications gateway that offers multiple functions and features for specific geographic venue locations, while providing easy access to advertising, purchasing, and redemption opportunities for that specific geographic venue location. Venue locations can be stadiums, shopping malls, amusement parks, open air spaces where people can congregate, and/or buildings, which most often require the presence of a concentration of people. The venue location may correlate to the location of the hand-held mobile unit or it may be a remote geographic venue location not near the location of the hand-held mobile unit. Access to the gateway application is through a hand-held mobile unit, which can include a mobile phone, smartphone device, or portable computer having a wireless radio transmission connection. (e.g. iPhone, Droid, iPad, Slate, etc.)

The apparatus includes a plurality of amplifiers corresponding, respectively, to the plurality of twisted-pair communication links, each amplifier having a sufficiently high input impedance and common-mode voltage tolerance to non-intrusively copy a data signal transmitted through a corresponding twisted-pair communication link and amplify the copied data signal. The apparatus further includes a plurality of isolation transformers corresponding, respectively, to the plurality of amplifiers, each isolation transformer receiving the amplified, copied data signal from the corresponding amplifier, and outputting a transformed data signal, and a connector receiving the transformed data signals from the plurality of isolation transformers in a pin order corresponding to the plurality of twisted-pair communication links. A protocol analyzer is also provided to receive the transformed data signals via the connector for decoding and monitoring purposes.
Abstract:
Disclosed is a system that monitors the signal strength of each transmission by a node on a LAN cable of a local area network and determines the location of the node sending the signal. This system has a monitor at each end of the LAN cable, with one of the monitors typically being located in a computer node attached to the cable. When an information frame is sent on the cable, each of the monitors records the signal strength of the frame preamble and the source address contained within the frame. The distance to the node from a first end of the cable is calculated based on the signal strengths. A LAN collision trap circuit transmits a pseudo frame signal, of maximum length, periodically and monitors any collision or jam signals that occur during the pseudo frame. If a collision or jam is detected, a collision/jam information bit and the signal strength and time of the collision or jam, relative to the beginning of the pseudo frame, is recorded in a FIFO. Software within the system reads this FIFO, and determines, based on the collision/jam information bit and time, if a valid early collision, an invalid late collision or a jam was detected. If a late collision or jam was detected, the software determines the defective node by comparing the signal strengths of the collision or jam signal to the strengths measured by the LAN level monitor and displays the address and location of the defective node that caused the late collision or invalid jam.
Abstract:
A surface for reflecting light energy of a first frequency range while transmitting light energy of a second frequency range and an incandescent lamp employing such a surface utilizes an array of corner cube elements. Each element has three sides which are mutually perpendicular and meet at a common vertex. Each side of each element is a surface in the shape of a square. All edges of the three square sides have equal dimensions. The array of elements is arranged with each element except for extreme outer elements having all of its edges contiguous with corresponding edges of other elements so as to form a continuous surface of the elements such that the projection of outer edges of each element on a common plane through corners of each side diagonally opposite to the vertex of that element form a hexagon. At least one surface of each element being dichroic to allow transmission of light energy of the second frequency range while reflecting light energy of the first frequency range.
Abstract:
In accordance with the present invention, a laser device is formed on an integrated circuit substrate, such as a silicon chip by sandwiching a thin-film amorphous semiconductor between reflective electrodes. The upper electrode is made only partially reflective so that, when an operating potential is applied between the electrodes, a stimulated emission of light energy in the infrared range is observed and this emission occurs through the upper electrode. To form a light amplifier, the lower reflecting electrode is omitted, so that the amorphous semiconductor and the substrate form a heterojunction which has low infrared reflectivity. In operating the amplifier, a potential is applied between the upper electrode and the substrate to control amplification. Incident radiation passes through the upper electrode and into the amorphous semiconductor and substrate and, in the process, is amplified in accordance with the value of the applied potential. This permits the incident radiation to be modulated in accordance with the applied potential. In a preferred embodiment incorporating the invention, at least one laser and an amplifier are incorporated on the same substrate as electronic circuits handling information signals. The laser is a source of light radiation and the amplifier is controlled with a voltage signal from the electronics to modulate laser radiation. Radiation is coupled between the laser and the amplifier and also out of the amplifier by means of optical wave guides which are fabricated on the substrate. The modulated radiation in the wave guide from the amplifier can then be provided directly to a fiber optic "transmission line".
