Abstract: A method of creating an application-based subnet for enhanced telephony call processing includes the steps of determining during the processing of a call that the call may require additional call processing services available at a second node located within an application-specific subnet, and transferring the call and call control to the application-specific subnet for further call processing.

Abstract: A networked system of voice-activated dialers is described. When a calling party using a local voice-activated dialer utters a phrase which indicates that information to reach a called party may be available at a remote site, a network connection is established to the remote site, spoken words or phrases are transmitted to the remote site, and the called party information is obtained from the remote site. The called party information is used to provide additional networked services to the calling party such as call-completion, voice messaging, or paging. These additional networked services may use the Public Switched Telephone Network (PSTN) and an existing signaling network such as the Signaling System No. 7 network.

Abstract: An object locating system, especially for use in locating a gaming ball in the game of football, utilizes a series of three sensors positioned on one side of a football playing field and a calibration source positioned on the other side. The calibration source emits an ultrasonic signal which is received by the sensors in order to provide a calibration signal. A ball marking unit is positionable on the field at a location of the ball and emits an ultrasonic signal which is received by the sensors and an RF signal which is received by the calibration source in order to turn the calibration source off. The sensors provide signals in which a processing unit calculates time delays by a time acquisition process in order to determine the position of the ball. In an alternate embodiment, the ball marking unit emits only an RF signal which is received by the sensors. The sensors again provide signals which are analyzed by the processing unit to determine delay between receipt of the signals at the sensors.
