Methods and systems for remotely configuring and monitoring a communication device are provided, especially useful in a computer network environment such as the Internet. A communication device or network appliance compares communications entering the communication device to a list of communication types established as known security risks, for example hacker attacks, unauthorized attempted access to network resources, or similar network security threats. If the received communication corresponds to a known security risk, the communication is classified as either a high security risk or low security risk, and an alert signal is transmitted to a remote monitoring center. Upon receiving the alert signal, the remote monitoring center assigns a priority to the alert signal based upon the type of the communication that triggered the transmission of the alert signal. Based on the assigned priority, the prioritized alert signal is then forwarded to a remote monitoring agent for resolution. The remote monitoring agent may then analyze the communication, contact the end user of the communication device with an appropriate resolution, or take other appropriate action in response to the received communication. The communication device may also be remotely configured.

The present invention relates generally to automatic insurance verification, and more specifically, to a non-invasive method and system for automatically determining, by any person with computer, wireless, or telephone access and in real-time, if an insured object of value is or is not insured irrespective of insurer location, jurisdiction, language, type, time, and also the internal operations, software platform and communications protocols used by insurers and / or governmental entities. It is an insurance verification, not an insurance reporting or tracking system and because it maintains no personal data of any kind, and can modify no record, it can deliver only very limited features regarding reporting or tracking. The present invention can however, provide absolute assurance of current insurance status at all times, provides a unique method of access which resolves all current failures and is non-invasive, providing complete privacy for all parties involved, (the absence of all personal information and the access method used ensures that all access and data is inherently non-invasive). This invention further ensures that any check of status, at insurer or governmental registration, (including “e-registration”, inspection, or any other location and time when and where a jurisdiction or insurer requires such a status check, will result in an instant and totally accurate status response. This system is based upon the assignment of a unique identifier, also known in this present art as a “UC” or “Unique Code” which then provides a method of accurate data, (including status checks), without reliance on “VINs”, (vehicle identification numbers), policy number or other identifiers which are often incorrect. The UC is assigned to any combination of two or more elements that are “gleaned”, (file field extraction and related system and methods), one of which is always current status. The extraction of these selected fields from data streams may be done by a number of prior art techniques, and the three most common have been detailed. First demonstrated to government officials in 1999 as a medical version and later the same year as a vehicle version, it has been demonstrated and documented since to a great many Federal and State governmental entities. This present invention has also been demonstrated to several foreign governments but incorporates no technologies that create any possible security risk for any government, insurer, individual, and especially to the national security of the United States.

A video endoscope in which the imaging chip at the distal tip is connected to the proximal connector and operator console by an optical fiber. Video data (preferably digital) is impressed on the optical fiber by a pulse-code modulator (PCM) circuit and light emitter with lensing. A small, inexpensive, flexible optical fiber in the endoscope body conveys the PCM optical data to the receiving circuit, preferably via an optical connector at the proximal end of the endoscope, and to decoding and display circuits in the operator console. The fiber optic transmission overcomes the difficulty of electrical transmission of wide band (digital video) signals via miniature cables, which can be expensive, bulky, inflexible, susceptible to noise and interference, and constitute a potential electrical safety risk by leakage currents. The PCM circuits may be integrated into the camera chip.
