Abstract: Systems and methods of monitoring radio channels and automatically providing selective notifications through a network that messages containing useful information, transmitted in the form of voice content, have been received. Keywords are compared with textual data transcribed from voice messages receive on a radio channel. The textual data and the keywords are compared, and upon identifying a correlation therebetween, a notification is automatically generated that indicates receipt of a given message, the existence of the correlation with the keywords, and an identity of the channel, so that client terminals can receive the message and also receive subsequent or related messages.

Abstract: A network audio feed source terminal, for coupling units of audio content from an audio source to a network. The feed terminal includes a source interface that receives audio content from the audio source and a content monitor that identifies audio content in accordance with monitoring criteria. The feed terminal also includes a means for capturing a selected portion of the identified audio content as units of audio content in accordance with capture criteria, and, a network interface that couples the units of audio content into the network.

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: 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.

Abstract: An apparatus for processing signals produced by signal sources, including a first signal source that is a first server of streaming audio signals, which include intermittent audio content, and which is located at an address on a network. The apparatus includes a network interface and a processor that selects the first signal source by outputting the address of the first server to the network interface, thereby establishing a network connection. The apparatus also includes a threshold detector coupled to receive streaming audio signals through the network interface, and that has a detector output with an active state that indicates that the intermittent audio content presently meets a threshold value. The processor further couples the streaming audio content to an output circuit if the detector output is active. The apparatus may further include a scanning radio receiver that is used as an alternative source for audio signals with intermittent content.

Abstract: A frequency scanning radio receiver scans and receives transmissions on discrete radio frequencies. The frequency scanning radio receiver is programmable to monitor frequencies in a geographical area where the receiver is located. The receiver is coupled to a communication device, located externally or internally of the receiver, for communication with a positioning system, such as the global positioning system, to determine the geographical location of the frequency scanning radio receiver either automatically or in response to a manual request. A data base of frequency allocation data, either internal to the radio or in a remotely located host system, provides frequency data to a memory in the frequency scanning radio receiver based on geographical location of the receiver determined through the communication device to program the receiver to monitor local radio frequency transmissions.

Abstract: A frequency scanning radio receiver programming system includes a frequency scanning radio receiver that scans and receives transmissions on discrete radio frequencies. The frequency scanning radio receiver is automatically programmable to monitor frequencies in a geographical area where the receiver is located. A host system including data bases of frequency allocation and geographical information assembles and sends frequency data to the frequency scanning radio receiver to program the receiver to monitor local radio frequency transmissions. The frequency data also includes identification of the transmitting parties and the frequency scanning radio receiver displays identification information to a listener.

Abstract: An improved frequency synthesizer utilizes a first order loop and sample-and-hold phase detector with optimized gain to obtain very fast frequency locking characteristics. In addition, synchronization of the programming of the loop divider and of the range shifting the voltage controlled oscillator is also utilized. An adaptive loop filter is provided to allow a first order loop to be used for lock acquisition and still maintain excellent noise performance after lock has been obtained.

Abstract: A high frequency divider suitable for use in a frequency synthesizer using a dual modulus prescaler and two counters to achieve high speed and low current drain. The input signal is alternately divided by one of the two moduli in the prescaler and then alternately divided by one of the two counters. Each of the two counters is reset while the other is counting thereby reducing circuit complexity and increasing circuit speed.
