One embodiment of an alignment apparatus for aligning an object, such as a tool or other implement, perpendicular with respect to a horizontal or a vertical target surface, comprises a three-axis accelerometer and at least two forward-facing distance sensors and a projection display comprising four addressable laser projectors. The accelerometer and distance sensor outputs are mapped to a predefined graphic symbol representing the orientation of the tool relative to the target surface, in particular when the tool is perpendicular to the target surface. The projection display projects the predefined symbol onto the target surface where it may be easily viewed by the tool operator allowing the operator to make any necessary corrections to the tool position.

An apparatus includes a strap that is positional about a drill and maintains a static relationship therewith while a drill bit and chuck rotate. The apparatus includes a plurality of light sources and sensors. The light sources and sensors face forwardly and emit corresponding light arrays aligned parallel to the drill bit and measure a linear distance to a target surface respectively. Each light source defines a reflection that has a unique diameter when the drill is not perpendicular, notifying the user to adapt the drill such that identical diameters are reflected on the work surface. A mechanism communicates an output signal to a display screen so that a visual representation of the drill bit location becomes displayed on a display screen. The drill bit is aligned perpendicular to the work surface when the light sources are equidistantly spaced from the work surface.

An arm supporting exoskeleton comprises a shoulder base coupled to an arm link mechanism. The arm link mechanism comprises a proximal link and a distal link configured to rotate relative to each other about a rotating joint; at least one arm-coupler adapted to couple a user's arm to the distal link; a tensile force generator coupled to the proximal link and the distal link, and providing a torque to flex the distal link relative to the proximal link; and a protrusion located substantially at the rotating joint. When the distal link extends past a toggle angle, the protrusion constrains the tensile force generator, and the torque provided by the tensile force generator remains substantially small. When the protrusion does not constrain the tensile force generator, the torque tends to flex the distal link relative to the proximal link, thereby reducing human shoulder forces and torques required to raise the user's arm.
