International Classification:
H04N 718
US Classification:
358100
Abstract:
A video inspection system for hazardous environments is provided, comprising a housing, sealable so as to contain a pressurized gas therein, having a view opening therein and further including a valve for introducing pressurized gas into the housing, connected to the housing; and a transparent lens, sealingly affixed across the view opening; a camera for recording visual images through the view opening, mounted within the housing; and a power supply, for powering the camera, mounted within the housing and operatively connected to the camera. A method for operating the above system is also provided, including the steps of substantially purging undesirable gases from the interior of the housing; sealing the housing, eliminating external connections thereto; introducing non-flammable gas to the interior of the housing until the pressure in the housing reaches a desired level; and operating the camera within the housing. The system may also be operated as a portable lighting system without the camera and may utilize fiber optics communications to transmit contemporaneous signals from the camera in a hazardous environment.

Belt Mounted Beverage Container Holder
US Patent:
2010029, Nov 25, 2010
Filed:
May 21, 2009
Appl. No.:
12/469741
Inventors:
John Sentell - Baton Rouge LA, US
International Classification:
B65D 81/38, A45F 5/00
US Classification:
2241483, 2241484
Abstract:
Disclosed is a waist- or belt-mounted beverage container holder. A belt clip attaches to the user's waist or belt. A soft-sided, collapsible pouch has sides, one closed end and one open end, forming a cavity sized and shaped to accommodate a beverage container such as a can or bottle inserted into said cavity. The pouch has a mounting stud fixed to it. A beverage container is placed into the pouch, and the mounting stud is slid into a channel on the belt clip, so that the beverage container is suspended from the user's body. When desired, the beverage container (in the pouch) is lifted up, sliding the mounting stud out of the belt clip, and the beverage is consumed as desired. Reversing the process permits the user to suspend the beverage container from his or her body, leaving both hands free.
