Abstract: An all-purpose, multi-use touchup tool designed for home, office, and general construction work for producing a pleasant, show-quality finish to the construction project. The system generally includes a multitool having up to ten functional touch-up tasks capable of being performed thereby, including multiple blade edges, brushes, and measuring elements. A holder element can be joined with the multitool to expand the functionality of each. The system could include other touchup tools and elements such as a storage cup, wipes, and additional brushes and sanding elements.

Abstract: A phototherapy mouthpiece includes a mouthguard including a light source and a power pack extending power therethrough a cable to the light source mounted for converting the power to red or near-red photon light, in order to convert the photon energy to proton-motive energy in the gum margin, so that gum cells can replicate to heal gum tissue. The mouthguard portion forms a plurality of recesses and air ducts to enhance oral osmosis. Optionally, a power pack based light source can deliver red or near red photon light through an optic cable to achieve the same proton-motive energy effect, but with less load on the jaw.

Abstract: A combination blower and trimmer assembly including a centrifugal clutch transmission for shifting a drive shaft driven by a motor between engagement with an impeller of the blower and engagement with a drive shaft of the trimmer for selective operation of either the blower or trimmer.

Abstract: An engine is connected to the upper end of a drive shaft housing and a work head with a string trimmer or blower or both is operatively connected to the lower end of the drive shaft housing and is rotatably driven by an engine rotating a drive shaft inside the drive shaft housing and connected to the working head. The drive shaft housing is rigidly connected to the working head and may be rotated about its longitudinal axis relative to the engine in any desired amount of rotation, but the preferred degree of rotation is 135° to move the working head from a trimming position with the rotating trimmer string in a horizontal position to an edging position with the rotating trimmer string in a vertical position and with the working head being displaced to the operator's right side for better viewing and control and operator comfort.

Abstract: An auxiliary harness supported by right or left shoulder to suspend the string trimmer at or near a fixed point somewhat central to the torso having a carrying case, a string trimmer quick release button, an on-off lock to release or fix a retractable cable from a spring loaded spool, the cable fitted to the string trimmer and the operator by harness clips, the cable having to provide a longitudinal span to dampen lateral kickback and longitudinal flutter and to relax one or more trigger fingers, the operator having to adjust the cable and the boom slightly without having to remove the harness, the cable made of firm or elastic material having to dampen an operator's foot movement and the string trimmer vibration with a two-way longitudinal span embodiment or maneuvers the string trimmer with a single loop embodiment, and the harness providing steps to relieve operator fatigue.

Abstract: A combined edger, trimmer and blower generally referred to as a lawn care apparatus for tending vegetation. More particularly, a novel handlebar provides a power control handle to maintain a boom on a longitudinal line of symmetry from a fixed point to an upright motor assembly in response to a side control handle rotating and translating the boom from a gearbox to a tangential tool assembly in front of an operator on a lateral line of symmetry. The gearbox including one or more lateral hubs that quick couples the side control handle into either a right or left handed holding position when the fixed point is to the side of an operator. The gearbox further containing one or more orthogonal gears with one or more gear addendum cams to lock the tangential tool assembly into a vertical or horizontal operating position, that is, a narrow or wide operating framework.

Abstract: A shield with a cutting disk having minimum weight with respect to a boom holding angle, the cutting disk dampened at a shield protective by a wind tunnel, the wind tunnel forming a high-pressure cylinder having a reciprocal fluid flow inlet and outlet with a small trough capable of removing a significant amount of debris, the wind tunnel allowing a portion of the cutting disk to pass through the cylinder to stabilize the cutting disk transverse flow, the wind tunnel having one or more oval or straight blades separating a portion of the cutting disk from the shield to stabilize the cutting disk tangential flow and can be placed downwind of prevailing breezes and the cutting disk stabilized by turf grass.

Abstract: A grounds maintenance tool sends power to a grounds trimming or lawn edging orthogonal isometry from about an identical transport route, the tool orthogonal isometry is orientated by an upright power control handle and a three-way lateral control handle that is sometimes used as a bar arm, the power control handle provides a rear arm rest that also contains shaft stops and a power control trigger with one or more speeds to keep an index finger in about identical tool operating frameworks, the longitudinal power control handle, lateral control handle and the auxiliary shoulder harness creating a congruent orthogonal isometry on the shaft center of rotational symmetry, the cutting disk bringing the string line filament inner and outer spool out in radius to obey elasticity laws, the cutter stabilizes quickly, the guard side walls are folded to wing ends, the three main skids are stabilizers and the arm rest is a wand.
