A portable paint station that includes a work table and a pair of legs that are positionable in a retracted position and an extended position. In one form, the paint station provides a work surface that may be selectively positioned at two distinct heights. In another form, the paint station provides a work surface with a roller tray recess that may be selectively covered to resist the formation of a skin on paint that is located in the recess. In a further form, the paint station provides a work table with a pair of legs. At least one set of the legs has a handle aperture that may be employed to hand carry the paint station on its side. In yet another form, the paint station includes a roller tray assembly that facilitates the short-term storage of a paint roller that is loaded with paint.

A work box to be combined with a work table has a base with at least one extending side wall enclosing a tool retaining area. An interruption is formed in the base to define a gap for receiving a support on the work table. The support mounts the base and, in turn, the work box onto the support and the work table.

A lock set installation apparatus has a pair of hole saw guides which locate a hole to receive door operating members of a lock set. Each hole saw guide has at least one rail member which oppose one another. A lock bolt hole mechanism is movable and coupled with the rails. The lock bolt hole mechanism centers the lock bolt hole onto the door. A locking mechanism locks the hole saw guides with respect to one another to enable cutting of the door.

Various embodiments of the present invention are directed to nanowire crossbars that use configurable, tunneling resistor junctions to electronically implement logic gates. In one embodiment of the present invention, a nanowire crossbar comprises two or more layers of approximately parallel nanowires, and a number of configurable, tunneling resistor junctions that each interconnects a nanowire in a first layer of approximately parallel nanowires with a nanowire in a second layer of approximately parallel nanowires.

One embodiment of the present invention is a nanoscale shift register that can be used, in certain nanoscale and mixed-scale logic circuits, to distribute an input signal to individual nanowires of the logic circuit. In a described embodiment, the nanoscale shift register includes two series of nanoscale latches, each series controlled by common latch-control signals. Internal latches of each series of latches are alternatively interconnected with a previous latch of the other series and a next latch of the other series by two series of gates, each controlled by a gate signal line.

Various embodiments of the present invention are directed to antisymmetric nanowire-crossbar-circuit designs. Antisymmetric nanowire crossbars are composed, in certain embodiments of the present invention, of two or more microregions that receive input signals and two or more microregions that send output signals. Antisymmetric nanowire crossbars may include a nanowire-crossbar network having signal paths that carry signals between one or more of the microregions. The nanowire-crossbar network may also carry signals between external electronic devices and one or more of the microregions. Antisymmetric nanowire crossbars may additionally include two or more structures that supply voltage and ground.

Reconfigurable logic devices and methods of programming the devices are disclosed. The logic device includes a look-up table (LUT) and at least one storage element configured for sampling LUT output signals. The LUT comprises a plurality of input signals, an array of programmable impedance devices operably coupled to the input signals, and the LUT output signals. Each programmable impedance device in the array includes a first electrode operably coupled to one of the input signal, a second electrode disposed to form a junction wherein the second electrode at least partially overlaps the first electrode, and a programmable material disposed between the first electrode and the second electrode. The programmable material operably couples the first electrode and the second electrode such that each programmable impedance device exhibits a non-volatile programmable impedance. The array may be configured as a one-dimensional or two-dimensional array.

A support stand for a tool such as a miter saw is disclosed. The stand includes legs, a beam supported by the legs, and a pair of tool support platforms that may be connected to the tool. The tool support platforms are configured to slide along the beam; moreover, they can be removed from the beam and placed on a supporting surface. Each platform may include a receptacle that engages a clip fastened to the beam. The clip engages the platform to prevent its movement along the beam. Each platform also includes a series of slots through which fasteners are inserted. The slots allow the fasteners to be repositioned so they can be aligned with the specific connection points on a variety of different tools (including tools of different manufacturers).

Various embodiments of the present invention provide methods for allocating nanowire junctions in a nanowire crossbar having one or more randomly distributed non-functional crossbar nanowire junctions. In certain embodiments, the method constructs a circuit graph based on the circuit and constructs a crossbar graph based on the nanowire crossbar. A search is then conducted, in the embodiments, in order to determine a monomorphism that respectively maps the nodes and edges of the circuit graph to a subset of nodes and a subset of edges of the crossbar graph. The subset of nodes and subset of edges of the crossbar graph can then be used to allocate nanowire junctions in the nanowire crossbar.
