Abstract: A system and method to efficiently use a plurality of ‘receivers’ to monitor a larger plurality of ‘sources’ for audio content. Upon identifying that a source is active, one of the plural receivers is assigned to convey the content to a destination. All other receivers are prevented from monitoring that specific source for the duration of its activity, but continue to monitor the remaining sources. ‘Source’ includes any source of information containing audio content. ‘Receiver’ includes any device capable of selectively conveying such content, including physical switches, hardware or software multiplexers, microphones, radio receivers, or any other means of obtaining such content.

Abstract: A system and method of communicating audio through a network. The method includes detecting audio content from an audio source by a first network terminal, sending a directory packet including a network address of the detected audio content to a second network terminal, and requesting the audio content through the network by the second audio terminal. The further step of storing the detected audio content in a buffer for audio packets identified by packet identities may be added. The sending a directory packet step may include sending a packet identity, and the requesting step may include specifying an audio packet according to the packet identity. A further step of sending a source packet including the network address of the detected audio content to a network directory server by the first network terminal may be added. The network directory server may execute the sending a directory packet step.

Abstract: Audio content distribution from audio sources to client terminals through a network. An audio source interface receives raw audio from an audio source, and converts it into a digital audio clip in a digital audio packet, containing a timestamp and a channel identity corresponding to the audio source. A network audio server formats the digital audio packet into a network compliant digital audio file, which is stored at a network address. The network audio server generates a directory packet including the address of the digital audio file, the channel identity, and the timestamp, and, couples the directory packet to a directory server located on the network. The directory server outputs a directory stream to a client terminal on the network, which selects a directory packet and sends an audio file request through the network for the digital audio file. The audio file is then sent to the client terminal.

Abstract: A network audio receive terminal. A receive terminal includes a network interface that receives network packets and a network packet scanner coupled to the network interface that sequentially scans received network packets in accordance with scan criteria. A content selector is coupled to the network packet scanner, and selects network packets containing units of audio content from the scanned network packets based on selection criteria, including pertinence data. An audio content processor is coupled to the content selector, and processes the audio content in the selected network packets. The network packets may include directory packets containing audio content addresses, in which case, the content selector further selects directory packets based on selection criteria. An audio packet requestor requests audio packets through the network identified by the audio content addresses that correspond to the selected directory packets.

A needle is connected to the hub and extends through the first opening at the first end. Access to the needle through the second opening is prevented by a sterility barrier, which has a movable portion that is moved along a longitudinal axis of the needle to provide access to the needle. A storage container includes a housing having a plurality of cavities to receive a plurality of pen needles. A cover is rotatably connected to the housing and is rotated such that an access portion thereof is aligned with one of the cavities, thereby providing access to the pen needle in the cavity.

Abstract: A satellite or spacecraft in low Earth orbit, when in eclipse and not illuminated by sunlight, represents a low-bandwidth datastream through modulation of a source of uncollimated light, such as a set of light emitting diodes. Transmission modes include generating patterns in the color, intensity or polarization of a light source, or precise timing control of a strobe signal. A ground station tracks the satellite in a telescope, stewing the telescope to follow the satellite as it moves across the sky, recording light generated by the satellite with a light sensor such as a video camera. The datastream is regenerated through analysis of recorded video. Satellite downlink is initiated by detection of eclipse, by command via radio uplink, or in response to a periodic automatic timer. In an alternative embodiment, the satellite represents the datastream through modulation of its effective albedo or reflective flux during periods of solar illumination.

Abstract: The invention provides an apparatus and a method for determining the frequency of a radio frequency signal. The coherency of a received signal is determined and only the frequency of a coherent signal is determined. Zero amplitude transitions of coherent signals are counted in respective time periods. If the counts in each time period agree within a quantization error, the accumulated counts for a fixed time period are employed to determine a frequency. The frequency determining apparatus and method are particularly useful with a frequency agile radio receiver for detecting the presence of radio frequency signals from nearby mobile and stationary transmitters. Upon determination of the frequency of the nearby transmitter, the channel of transmission can be determined from a memory within the receiver and the receiver can be tuned to monitor the transmission. Additional tests to verify the frequency determination may be applied using squelch and window detector circuits of the radio receiver.

Abstract: Methods and systems for detecting an energy emission event are provided. In a method for detecting an energy emission event, a reference event signal is compared with a received event signal. In some embodiments, the reference event signal is associated with radiated energy having a predetermined temporal response. A detection signal is output when the received event signal corresponds to the reference event signal. In response to outputting the detection signal, imagery of a location in proximity to where the received event signal originated is captured or processed. Using the captured imagery and the detection signal, a determination of where the received event signal originated is made.
