Abstract: Disclosed are systems, methods, devices, and apparatus to interrogate a clothed individual with electromagnetic radiation to determine one or more body measurements at least partially covered by the individual's clothing. The invention further includes techniques to interrogate an object with electromagnetic radiation in the millimeter and/or microwave range to provide a volumetric representation of the object. This representation can be used to display images and/or determine dimensional information concerning the object.

Abstract: A system and method for detecting perforations in a body cavity. A fluid (liquid or gas) is delivered into a body cavity to slightly pressurize the cavity. A pressure sensing system monitors the pressure within the cavity for a predetermined test period. If cavity pressure is not substantially sustained during the test period, the physician is alerted to further assess the cavity for perforations before initiating treatment within the cavity. In a preferred form of the system, a medical treatment system such as an RF ablation system is provided with perforation detection functionality. The system preferably includes a pre-test and post-test lockout system. The lockout system prevents RF power delivery unless, during a predetermined test period, the pressure sensing system determines that no perforation exists, or unless a previously performed perforation detection procedure determined a perforation was present but the lockout system was subsequently overridden by the physician.

Abstract: A combination golf club and weeding device is disclosed. A cutter is attached to the lower portion of the club head and oriented so that weeds can be cut by swinging the club in the same fashion as is used in striking a golf ball. The shape of the cutter requires that the club be swung accurately in order to achieve a successful cut. When the cutter is retrofitted to a conventional club, reliefs are cut in the club head so that the entire assembly has the same mass and moment of inertia as the original club.

Abstract: A new illuminatable bag for enabling a user to locate items disposed within the bag. The inventive device includes a bag portion having a hollow interior. The bag portion has a battery chamber formed therein. A pair of lights are secured within the hollow interior of bag portion. The pair of lights have wiring extending downwardly therefrom to couple with connectors of the battery chamber. Batteries are removably positioned within the battery chamber. The batteries communicate with the connectors of the battery chamber for powering the pair of lights.

Abstract: A liquid carrier fluid that is used as a carrier system to suspend and deliver water soluble polymers which act to adjust the rheological properties of the aqueous systems to which they are added.

Abstract: Apparatus including a plurality of selectively positionable and securable thermal switches selectively positionable within an engine compartment. The switches include clamping ends to secure the switches to spaced terminal blocks in association with electrical circuitry of an associated automobile. Upon completion of a circuit through a thermal switch, an audible horn in association with an optionally utilized warning lamp is actuated to effect warning of a thermal threshold within operation of an associated automobile engine.
