  • Patent number: 11283972
    Abstract: Disclosed is an enclosed camera apparatus for use in applications with high temperature and/or airborne powder. The apparatus includes a housing enclosing a camera, with air moving within the housing that cools the camera and pressurizes the housing such that some air expels through a camera outward viewing orifice (aka “camera hole”), such that the camera can look outwardly through the orifice without powder accumulating around and atop the camera lens and/or camera viewing orifice. The camera is held in place by a machined camera mount that centers the camera on the orifice and allows compressed air to pass over the camera and the cable to protect it from overheating. The machined camera mount allows compressed air to pass back through the rest of the housing after it cools the camera to cool the rest of the housing, including the power and signal supply lines of the camera, before it exhausts out the top.

  • Patent number: 10792512
    Abstract: A modular structure is disclosed that shields people from radiation typically encountered in radiotherapy rooms. The structure can be easily assembled without cracks. Moreover, the structure can be assembled and repaired quickly, without interrupting treatments for long periods of time. The structure is made of two general types of modules. A base module is made up of two cuboids fused along facing long edges and offset, one from the other, both vertically and horizontally. A complementary module is made of a single flatter shaped cuboid. It is designed to fill gaps that appear at the top and bottom of the assembled array of base modules. These modules, as configured, allows several structures to be assembled by quick and simple fitting and horizontal and vertical stacking of the modules. The modules can be manufactured from low cost materials such as metal casing filled with metal powder.

A borescope is provided in communication with the combustion chamber and is operable to communicate images of the combustion chamber to the high-speed imaging device. A high intensity light source, for example, a xenon light source, is operable to substantially illuminate the combustion chamber. The high-speed imaging device and borescope are in axial alignment with respect to each other and are mounted with respect to the internal combustion engine. A method of imaging the combustion chamber of the internal combustion engine during engine operation employing the disclosed in-cylinder imaging apparatus is also provided.

  • Patent number: 7215358
    Abstract: The present invention relates to a motor-less automatic retraction device that can insert a vision tube capable of monitoring the inside of a furnace to mange the internal state of the furnace and control the temperature of the furnace into the furnace and retract the vision tube from the furnace in a motor-less manner. A conventional retraction device is disadvantageous in that it is expensive, voluminous, difficult to install, thus requiring expert's help to install, and difficult to repair at the time of breakdown, and requires expensive repairing costs. In order to overcome the above-described disadvantages, an object of the present invention is to develop a motor-less automatic retraction device that can insert the vision tube into the furnace and retract the vision tube from the furnace using a spring, so the device is easily to install due to its small size and lightweight, is easy to repair, and allows repairing costs to be reduced.

  • Patent number: 7184076
    Abstract: A fluid-powered inspection camera adapted to be operated in a contaminated environment where an electric power supply is not readily available includes a housing having a tubular shell terminating at an open end. An imaging device has a portion arranged within the tubular shell in a spaced relation so as to define an annular chamber therebetween. The imaging device has an eye positioned adjacent to the open end of the body. A compressed fluid-powered motor is arranged within the body and has a compressed fluid inlet adapted to be connected to a suitable source of compressed fluid and also has a compressed fluid outlet. A generator is operatively coupled to the compressed fluid-powered motor and arranged within the body to electrically power the imaging device in proportion to the rate of fluid flow passing through the motor. Compressed fluid discharged from the compressed fluid-powered motor outlet passes through the annular chamber and is discharged through the open end of the body.

  • Patent number: 6724467
    Abstract: A system and method for viewing objects at a fire scene allows fire fighters to view objects, including persons, in a smoke and fire filled environment. The present invention utilizes two different techniques to discriminate reflections from an object from scattered reflections from smoke and fire. In one embodiment of the invention, the coherent nature of laser light is employed to pick out objects. Another embodiment of the invention utilizes a time-gated approach to select reflections from objects which are located a specific distance from the laser transmitter.
