Abstract: A method and system are provided for tracking a target with an imaging system. An example of a method includes activating a transmitter on the target. A detector system is activated on the imaging system. A signal from the transmitter is received at the detector system and an imaging device is moved to point at the transmitter.

Abstract: Emergency session systems and corresponding methods are described that allow a subscriber to initiate an emergency session over a communication network in anticipation of an emergency event. The emergency session system includes a subscriber database that is operable to store a plurality of subscriber profiles for a plurality of subscribers subscribing to an emergency service offered by a service provider. Responsive to initiating an emergency session for a subscriber, a control system accesses the subscriber database to identify a subscriber profile for the subscriber. The control system identifies a first set of parameters for the emergency session from the subscriber profile, and performs actions based on the first set of parameters. The parameters may be pre-defined by the subscriber or dynamically entered by the subscriber.

Abstract: Systems and methods are described for providing text of a voice conversation of a voice call to one or more parties of the voice call. In accordance with one embodiment of the invention, a voice conversion system receives voice traffic from the voice call and converts the voice traffic to text. A buffer system buffers the text, which represents the most recent portion of the voice conversation. Responsive to a request from one of the parties, the buffer system provides the buffered text for display on the party's voice call device (e.g., cell phone). The party may then view and navigate the text of the portion of the voice conversation.

Abstract: Systems and methods are disclosed for changing attributes of voice calls. During a voice call over a connection of a circuit-based network between a first station and a second station through a switching system, the switching system receives audio from the first station. The switching system also detects a code entered by the user of the first station. Upon detecting the code, the switching system changes one or more attributes of the audio received from the first station to generate audio with changed attributes. For instance, the switching system may raise or lower a volume of the audio, may raise or lower the frequency of the audio, may add or remove background tones, or change other attributes. The switching system then transmits the audio with the changed attributes to the second station.

Abstract: Systems and methods are disclosed for adding attachments to voice calls. A communication system for the invention includes a file server and a switching system of a circuit-based network. During a voice call connected between a first station and a second station over the circuit-based network, the switching system detects a code entered by the user of the first station. Responsive to detecting the code, the switching system transmits a query to the file server. The file server processes the query to locate one or more files stored in the file server. The file server then transmits the located file to the switching system. The switching system plays the file to the second station over the connection for the voice call.

Abstract: Methods and software products are disclosed for protecting against software piracy. When a customer purchases software, the seller performs an activation process by identifying a unique computer identifier (ID) for the computer system of the customer, and activating the software based on the computer ID, such as by encoding the computer ID on the media storing the software. When the customer attempts to install the software on a computer system, the computer system executes an installation process. The computer system identifies its own computer ID and the computer ID used to activate the software. The computer system determines if its computer ID corresponds with the computer ID used to activate the software. If the computer IDs correspond, then the computer system is allowed to install the software. If not, the computer system is prevented from installing the software.

Abstract: A method, software, and computer system for defending against virus attacks is described. Assume that a computer system receives an instruction to run an executable file. Before the computer system runs the executable file, the computer system determines if the executable file is certified to run on the computer system. If the executable file is not certified, then the computer system prevents the executable file from running. If the executable file is certified, then the computer system determines if the executable file has been modified since being certified. If the executable file has been modified, then the computer system prevents the executable file from running. If the executable file has been certified and has not been modified, then the computer system runs the executable file. Because many viruses are included in executable files, virus attacks may be prevented by requiring executable files to be certified before they can run.

Abstract: A method and camera system for capturing a scene in three-dimensional format is described. In the camera system, light sensitive elements receive light reflected off of a scene, and measure properties of the light. The X-Y coordinate system then scans the light sensitive elements an X-Y coordinate to measure X-Y coordinate information for the X-Y coordinate. The Z coordinate system measures Z coordinate information for the corresponding X-Y coordinate. The Z coordinate system measures the Z coordinate information by transmitting waves at the X-Y coordinate of the scene and receiving the waves reflected from the X-Y coordinate. The information system receives the X-Y coordinate information and the Z coordinate information from the X-Y coordinate system and the Z coordinate system respectively, and combines the X-Y coordinate information and the Z coordinate information to generate an image signal.

Abstract: A method of providing real-time Internet access to a caller using only a standard telephone and plain old telephone service. The method includes receiving at a local switch a destination number representing a request for Internet access from the caller; routing the call to an Internet server for providing the Internet access; converting the destination number to a URL at the Internet server; routing the URL from the Internet server to the Internet; receiving a response from the Internet at the Internet server, the response including digital information; and converting the digital information in the response to a voice message, the voice message including information from the Web site and prompts for the caller; and routing the voice message to the caller.

Abstract: A method for receiving and transmitting signals in a cellular radio network. The method comprising receiving a plurality of radio signals at different frequencies using a single radio receiver at the base station, scanning the incoming signals and saving the signals to a buffer with a first processor, reading, processing and time-multiplexing the buffered signals with a second processor, transmitting the time-multiplexed radio signal via a single physical link to a mobile switching center, demultiplexing the time-multiplexed radio signal into independent radio signals corresponding to the incoming signals at the mobile switching center with a third processor;, processing the independent radio signals with the third processor; and routing the independent radio signals to the proper end users.
