Abstract: A folding knife has an elongated blade having a pivot end and an opposed free end, the pivot end of the blade pivotally connected to a handle, the blade being movable between a closed position in which the blade is protectively received by the handle and an open position in which the blade extends away from the handle, a back lock element pivotally connected to the handle and having a block portion, the back lock element movable between a locked position in which the block portion operably contacts a portion of the pivot end of the blade to prevent movement of the blade from the open position to the closed position, and an unlocked position in which movement of the blade from the open position to the closed position is enabled, and a safety element movable between an engaged position and a disengaged position.

Abstract: Devices, systems, and methods for reducing stress on a blood vessel are disclosed herein. For example, a method of treating effects of dementia comprises positioning a damping device along an artery that provides blood to a brain of a person so that an inner surface of the damping device contacts an outer surface of the artery. Wherein an inner diameter of the inner surface changes in response to a wavefront of blood passing through the artery and thereby attenuates energy of the wavefront.

Abstract: Devices, systems, and methods for reducing stress on a blood vessel are disclosed herein. A damping device configured in accordance with embodiments of the present technology can include an anchoring member coupled to a flexible, compliant damping member including a generally tubular sidewall having an outer surface, an inner surface defining a lumen configured to direct blood flow, a first end portion and a second end portion, and a damping region between the first and second end portions. The inner and outer surfaces of the damping member can be spaced apart by a distance greater at the damping region than at the first or second end portions. When blood flows through the damping member during systole, the damping member absorbs a portion of the pulsatile energy of the blood, thereby reducing a magnitude of the pulse pressure transmitted to a portion of the blood vessel distal to the damping device.

Abstract: A pressure relief system and a non-intrusive, low chatter pressure relief valve for use with such as system are disclosed. The pressure relief valve allows excess pressure in a pressurized fluid line to flow through a flow return line to a fluid reservoir when the fluid pressure exceeds the valve's pressure limit setting. The establishment of a uniform channel between the valve stem and the inner surface of a housing in which the valve stem is slidably located, as well as the use of a vent and sight tube to remove air from the top portion of the housing upon a spring being compressed during the opening of the valve, reduces the occurrence of pulsation and vibration when the valve is cycled between its open and closed positions. When the valve is in its closed position, the bottom end of the valve stem is in close proximity to the inner surface of the main fluid passageway in the pressurized fluid line, but does not intrusively interfere with the flow of fluid through the main fluid passageway.

Abstract: A tamper resistant mixture adjustment screw arrangement for a carburetor. The arrangement includes a carburetor body having at least one air/fuel adjustment screw threaded therein. The adjustment screw has a threaded shank and a head portion. The head portion is defined by a smooth top surface and an undulant, uneven side surface capable of being engaged and mated by an adjusting tool having a complementary undulant, uneven side surface capable of being engaged and mated by an adjusting tool having a complementary undulant, uneven surface for initially adjusting the air/fuel mixture in the carburetor. A blocking curb extends from the carburetor body to a level which at least substantially corresponds to a projecting extent of each adjustment screw and being closely spaced to the screw head to prevent the screw from being turned by commonly available tools, but to permit the screw to be adjusted by the adjusting tool.
