A tool assembly includes a handle and a plurality of tools mounted to the handle. Several of the tools can be rotated between a closed position and an open position relative to the handle. The tools include a utility knife, a keyhole saw, a pry bar and a punch. Additionally, the tool assembly includes a recessed rasp for trimming an edge of a sheet of gypsum board.

A “Woodprint™” characterization and identification technique employs cameras (16), lighting (14), camera interface hardware (18), a computer (20), and / or image processing software to collect and analyze surface characteristics of pieces of wood (8) to track them through an automated production process in real-time with information that is specific to each wood piece (8), such as what machining is required, its value, and / or its destination. When a wood piece (8) reaches a point in the production process where a decision is required, its unique identity is used to retrieve appropriate information previously determined and assigned to the wood piece (8).

A portable sawhorse which comprises first and second beam sections which are pivotally connected together to form a storage housing, first and second leg assemblies at respective distal ends of said first and second beam sections, said first and second leg assemblies being pivotally connected so as to be storable within said beam sections, and reinforcing members extending between first and second leg assemblies to stabilize the same when in an opened condition.

The invention provides an extendable utility device including: a central housing; one or more extendable members attached to the central housing; one or more spirit vials (i.e., a level) embedded in the central housing; and one or more wall markers attached to the extendable members. The extendable members extend from and retract into the central housing, and the wall markers are individually positioned perpendicular to, and at the ends of each of the extendable members.

One embodiment of the present invention is a compact, low-cost, lightweight, versatile and easy-to-operate, processor-controlled carving and multi-purpose shaping device (“PCCMPS machine”). The PCCMPS machine that represents one embodiment of the present invention is configured, in part, similarly to common, commercially available portable wood planers and ubiquitous laser and ink-jet computer printers, with work pieces fed into the PCCMPS machine in a horizontal direction. The PCCMPS machine includes a motor-powered cutting head that can power detachable bits to drill, cut, shape, and rout a work piece under processor and computer control. The cutting head may be translated, under processor control, back and forth across the surface of the work piece in a direction perpendicular to the direction in which the work piece is fed into the PCCMPS machine and moved by motor-powered rollers. The cutting head may be translated up and down, in a vertical direction, approximately perpendicular to the surface of the work piece. The processor can thus position a cutting bit at any point on a surface of, near the surface of, or within the work piece, via a combination of lateral and vertical translations of the cutting head and horizontal translation of the work piece, and can control the speed at which the bit rotates as the computer moves the rotating bit from one position to another position relative to the surface of the work piece in order to carve and shape elaborate, three-dimensional designs onto the work piece.

A method and a system for forestry, in particular harvesting by means of a harvesting machine comprising a vehicle and a harvesting arrangement mounted thereon, is based on the fact that at least one position determining device (5), capable of determining the positioning of the harvesting machine by means of external wirelessly receivable signals, is arranged on the harvesting machine (1). A marking device adapted to apply a marking on pieces of timber obtained from trees is arranged on the harvesting machine. A control unit (8), suitably a computer, is arranged on the harvesting machine to control the marking device to mark the piece of timber with position information or a code corresponding thereto by means of position information received from the position determining device (5).

A method and system for operating a tree harvesting machine including a tree harvesting tool are provided. The method may include identifying a tree to be harvested, generating one or more tree position signals indicative of a position of the tree, and controlling movement of the tree harvesting tool toward the tree as a function of the one or more tree position signals. The system may include a tree position sensor operable to generate one or more tree position signals indicative of a position of a tree. The system may further include a controller operable to receive the one or more tree position signals. The controller may be further operable to generate one or more tool control signals for controlling movement of the tree harvesting tool toward the tree as a function of the one or more tree position signals.

The melon-holder includes an elongated base having a pair of jaws each pivotal about a separate side of the base. The jaws are pivotal from a melon-engaging position to a melon-releasing position. The jaws have a number of lateral spaces which are spaced apart from one another and which are adapted to receive a knife for cutting the melon into lateral slices while the jaws are in the melon-engaging position.

A hand-held jigsaw includes a saw blade and control element for automating a tracking the saw blade, the hand-held jigsaw, or both along layout lines. A sensor, preferably a camera unit, detects a layout line provided on a work piece.
