A security system and method for mass transit and mass transportation whereby high capacity mobile vehicles such as ships, buses, planes, trains and subways transporting large numbers of passengers or cargo, are continuously monitored and secured. Sensors are utilized to detect and alert the presence of radioactive or explosive materials on board as well as within close proximity of the vehicle. Sensors are also used to identify and track cargo and people, such as drivers, operators, employees, crew, and passengers, and provide continuous location and tracking thereof from the point of initial entry to the final point of exit. Additionally, a global positioning system (GPS) provides location data, and wireless data and telecommunications link provides two-way data and voice communication with any designated remote location by using one of several modes of wireless telecommunication. Cameras provide visual observation within designated viewable areas, and may be activated by any detection of motion, and are infrared or night vision capable allowing viewing even in extremely poor light conditions. DVR recording allow a huge amount of video content from the cameras to be digitally recorded, then played back later for further analysis. Finally, the Security System may optionally have an Internet Protocol (IP) address thereby allowing authorized persons to access the system from secured Internet connection.

A coaxial cable connector is provided with a generally tubular mandrel. An attachment element and a retainer are associated with the mandrel and a bushing is telescopically mounted on the retainer. The bushing is adapted for axial movement along the retainer to a closed position wherein the bushing biases a first portion of the retainer into sealing engagement with a seating surface on the exterior of the mandrel. The retainer is sufficiently translucent to permit visual observation of a cable inserted into the retainer.

In the field of dental care, diagnoses have been and being made by means of X-ray images, visual observation, explorer, palpation, fluorometery, insertion of a pocket probe and observation, observation by means of a root canal meter and the use of a Doppler flood flowmeter. However, such diagnoses are invasive and not very clear and three-dimensional X-ray CT apparatus that are being used for diagnoses are very large and complex. Additionally, OCT apparatus for obtaining optical tomographys by using reflection light that are being used by ophthalmologists give rise to problems because of the profile of the detection probe and operability when such an apparatus is used in an oral cavity that contains hard tissues such as teeth and soft tissues such as gingiva for dental care. The present invention dissolves the above identified problems and provides a non-invasive and high resolution dental optical diagnostic apparatus. A dental optical diagnostic apparatus (1) according to the invention comprises a means (30) for generating guide light to irradiate the dental part of a subject for viewing, visible light for picking up a surface image and signal light of low coherence light for diagnosing the dental part, a camera (69) for picking up a surface image of the dental part, an OCT means for acquiring an optical tomography and an image display section (5) for displaying the obtained images.
