Abstract: An ergonomic handle is disclosed for use with a power tool, the power tool having a power source, a housing containing a source of motion, and a tool holder coupled the housing and defining a tool holder axis and a forward direction toward a working end of the tool and rearward direction away from the working end of the tool. The handle includes a handle portion having a proximal end coupled to the housing and a distal end coupleable to the power source, and defining, from the proximal end to the distal end, a first region, a second region, a third region, and a fourth region, and defining a handle axis that is generally transverse to the tool holder axis. The first region includes a switch for actuating the source of motion and adapted to receive a user's thumb and forefinger when the forefinger is actuating the switch.

Abstract: An exercise arrangement includes a movable support that is movable in a fore-aft direction and simultaneously movable laterally, e.g. about a tilt axis. The support may be a platform movably mounted to a base. A roller and track arrangement may be provided between the platform and the base, to provide movement of the platform in the axial direction relative to the base as well as an axially neutral position of the platform relative to the base. The roller and track arrangement may be in the form of one or more curved roller and track engagement surfaces that extend in the axial direction and that provide a gravity bias of the platform toward the neutral position. The roller and track arrangement may provide tilting movement of the movable platform about the tilt axis. A tilt biasing arrangement biases the platform toward a neutral tilt position relative to the base.

Abstract: An ergonomic handle for use with a power tool defines a first region that includes a switch, adapted to receive a thumb and forefinger when the forefinger is actuating the switch, a second region adapted to receive a middle finger, a third region adapted to receive a ring finger; and a fourth region adapted to receive a pinky finger. Each of the second, third, and fourth region includes a generally oval cross section having a major axis and a minor axis. The longest major axis is in the third region, the shortest major axis is in the fourth region, the shortest minor axis is in the second region, and the longest minor axis is positioned in the fourth region.

Abstract: In an embodiment, a data storage and retrieval system includes a computing device that configures the computer memory according to an RTree (a type of logic tree) representing a structure of a spreadsheet. The computer memory may be internal to or external to the computing device. In an embodiment, the RTree has a plurality of nodes, at least some of which contain one or more minimum bounding rectangles. Each minimum bounding rectangle (“MBR”) encompasses cells of the spreadsheet from a different one of a plurality of columns of the spreadsheet, but does not encompass cells of any of the other columns of the plurality of columns. A node of the RTree may hold multiple MBRs or a single MBR.

Abstract: A feeding mechanism and method for feeding objects singulated from a bulk mass of objects includes receiving the bulk mass into a hopper system having a hopper screw set including first and second hopper screws and a plurality of feeding pockets defined by the thread forms of the hopper screws. Rotation of the hopper screws tumbles the bulk mass to cascade and singulate individual objects into respective feed pockets. An object set including at least one singulated object is discharged from the hopper screw set by rotation of the hopper screws. A discharge assembly including a ramp and star wheel receives the discharged object set, and transfers the object set to a discharge outlet. The object set output from the discharge outlet is received by a target defined by a receiving article. In one example, the object is rounded, the target is an opening of a container.

Abstract: A warm air solid fuel furnace is disclosed that includes a firebox defined by a floor, opposing sides, a top baffle, a front door, and a rear wall, wherein the firebox floor is at least partially lined with fire resistant material. A primary combustion air flow path includes one or more holes through the front door. A secondary air flow path receives air from a front of the furnace and conducts received air along a first opposing side of the firebox, up the rear wall of the firebox, and into at least one tube having orifices, the tube located beneath the top baffle. A rear pilot air flow path receives air from the front of the furnace and conducts received air along a second opposing side of the firebox, up the rear wall of the firebox, and into at least one hole through the rear wall.

Abstract: A vehicle includes an engine, an input device for controlling a speed of the engine, a seat for an occupant of the vehicle, a seat belt for securing the occupant in the seat, and a seat belt sensor for detecting when the seat belt is buckled. A controller may be operatively connected to the seat belt sensor and the engine for controlling the vehicle in a first mode when the seat belt is buckled and a second mode when the seat belt is unbuckled. The controller may perform various different functions, such as cutting fuel to the engine when the vehicle speed is equal to or greater than a predetermined threshold while operating in the second mode, or receiving input indicating that the input device is released before switching the vehicle to the first mode when the seat belt is buckled while the vehicle is operating in the second mode.
