Abstract: An improved brake light warning system is provided that warns the driver of an intelligent vehicle of the need to brake while simultaneously alerting the driver of a following car prior to the driver of the intelligent vehicle stepping on the brakes. A highly intelligent vehicle processor monitors inputs from various sources and compares the reactions of the driver of the highly intelligent vehicle to that of a virtual competent driver in the same context. In response to the presence of an obstacle, the leading car may brake or decelerate. The highly intelligent vehicle detects the response of the leading car via a remote sensing device, determines a context from the physical data, determines what the virtual competent driver would do, determines if the driver should brake, and sends a warning signal to the driver. In one embodiment, a pre-brake signal is also sent to the brake light assembly. The brake light assembly illuminates and is observable by the driver of the following car.

Abstract: A device capable of analyzing call progress event information from sensors connected to switched network circuits for the purpose of identifying the beginning and end of a telephone call. The invention also collects and analyzes all events occurring between the origination and termination of the call, providing a detailed description of both telephone user and network element actions. Abnormal events are identified during this analysis so that call quality can be determined. The invention can use information supplied by sensors that are intrusive or non intrusive to the switched network circuit.
