A sawhorse has a first pair of legs connected to a first bracket, the first pair of legs comprising first and second legs which are independently movable relative to one another, a second pair of legs connected to a second bracket, the second pair of legs comprising third and fourth legs which are independently movable relative to one another, and a head connected to the first and second brackets and spacing the first and second pairs of legs from one another. The legs can be moved from an extended position to a retracted or collapsed position where they extend along and generally parallel to the head. The sawhorse includes a latching mechanism which allows it to be connected to a second sawhorse for storage and transport.

A computer-implemented method for scheduling processing of an order for goods at a provider location obtains an arrival estimate for when a user associated with the order is expected to arrive at the provider location and uses the arrival estimate to schedule processing of the order. Processing may be scheduled so that completion of order processing is expected to substantially coincide with arrival of the user at the provider location. The method may also obtain an order completion estimate for when processing of the order is expected to be completed and use both the arrival estimate and the order completion estimate to schedule processing of the order. The method may update one or both of the arrival estimate and the order completion estimate. The method may be executed by a networked mobile wireless telecommunication computing device of the user, or by a data processing system associated with the provider.

A saw system capable of cutting through a workpiece in one stroke is provided. The saw system includes a base, a turntable mounted on the base for rotation about a vertical axis, a support structure defining a cutting axis and fixedly attached to the turntable, and an elongated blade including a cutting edge. The turntable has a substantially planar support surface for supporting a workpiece. The support structure includes a pair of parallel sliding members, wherein the sliding members are disposed in a direction substantially parallel to the cutting axis. The elongated blade is spaced apart from the sliding members and is movable along the sliding members. The cutting edge includes a proximal end and a distal end, wherein an angle between an imaginary line connecting the distal end of the cutting edge to the proximal end thereof and its projection onto the turntable is an acute angle.

A log lifting device for raising a log into a cutting position includes a cylinder, a handle, and a wedge. The handle is coupled to and extends from the cylinder equally distant from opposing ends of the cylinder. The wedge is coupled to and extends from the cylinder proximate to the handle. The wedge is substantially perpendicular to the handle. The wedge is configured to be positioned beneath a felled log, positioning a user to grasp and pull on the handle to rotate the cylinder to apply a lifting force to the log so that the log is supported upon the handle above a surface. The log thus is positioned to be safely cut by the user using a chain saw, or other log cutting implement.

A method for fulfilling a plurality of orders for goods at a provider location comprises obtaining an arrival sequence estimate for each of a plurality of users indicating the sequence in which the users are expected to arrive, and organizing completed orders according to the arrival sequence estimate. The arrival sequence estimate may be obtained by ordering users according to their respective radial distances from a target, and may also be used to schedule processing of the orders. Alternatively, arrival estimates for when each of the users is expected to arrive may be used to schedule processing of the orders. A dynamic arrival estimate may be obtained based on an expected travel path toward the destination during a first trip portion comprising travel within a constrained travel path network, and based on radial distance from the destination during a second trip portion subsequent to the first trip portion.
