The non-ferrous anticorrosive railroad bracket 10 includes a stainless steel threaded shaft 50 for preventing oxidation on moving parts. A sliding clamp plate mechanism 36 is for mounting to virtually any common rail 54 in use throughout the world. The bracket 10 includes a pointed wedge end 14 for providing under-rail installation by displacing stone gravel base underneath. It also includes a tool-less clamping rail attachment mechanism 32 requiring only hand-tighten for installation. There is a large knob-nut 34 for tightening and securing to the rail 54 by easily hand-tightening. A simple folded kick-plate 12 is utilized for kicking by foot, pushing by hand, and hammering so as to easily displace gravel, stones, slag, and other material. Lastly, the folded kick-plate 12 acts as a handle to carry the bracket 10 and an attached sensor detector unit 30.

Methods and systems are provided for imaging a microarray of a microarray assembly. The microarray assembly may be configured as a protein microarray and may be used to visualize protein expression levels in sample for disease detection and/or diagnosis. In one example, the microarray assembly may comprise a laser pointed in a first direction, a camera positioned parallel to and vertically below the laser, a first dichroic mirror vertically aligned with the laser for reflecting light emitted from the laser, a second mirror vertically aligned with the camera and horizontally aligned with the first dichroic mirror, and a chip coated in a nitrocellulose film and including an array of wells containing one or more biomolecules.

A bar bell comprises a plate-accepting bar that extends longitudinally between two end regions at which weight plates can be mounted, a longitudinally-extending handle positioned above the plate-accepting bar and supported by the barbell, a pair of barbell-supporting brackets positioned at respective end regions of the plate-accepting bar to stably support the barbell on a supporting surface without contact between mounted weight plates and the supporting surface, and at least one longitudinally-extending fulcrum bar affixed to the barbell in such a way that it is positioned to contact a users forearm during a bicep curl and create a lever arm vis--vis the handle that maintains the barbells center of gravity in a lagging position with respect to the users hands so as to exert enhanced resistance to the curling movement during the movement.

A dumbbell comprises a pair of frame members, each having a lower plate-like portion and an upper stem portion. The frame members are coupled together via spacer bars. An upper spacer bar is coupled to the frames members at the stem portions, and a handle is mounted for rotation about the upper spacer bar. Two lower spacer bars positioned near the front and back of the plate-like portions of the frame members. The frame members may provide the desired weight, either through choice of material, plate thickness or both, or the frame members may be provide a basic master weight plate for the dumbbell, with additional weight being provided by the addition of one or more weight plates to each frame member. Pads are mounted about the lower spacer bars, and are positioned to contact the wrist area of a user during exercise movements. A gap is defined between the pads through which the hand of a user may inserted to grasp the dumbbell in an upside-down orientation for secure control and comfort for certain exercise movements. The dumbbell may also be manipulated by the handle or stems for certain kettlebell exercises.

A cable attachment that permits the strap of an exercise machine to be replaced independently of the machines handle without the need for sewing machines or special tools such as crimping devices comprises a body having three juncture points arranged in a generally triangular relationship, the first point being near its top to accommodate the bodys attachment to the cable of the exercise machine, the other two juncture points lying below the first point and separated from each other by the center section of the body. The two lower junction points are configured to securely accommodate a removably-coupled handle-coupling strap, and are the locations to which the straps can be secured, preferably with a suitable knot. The two lower juncture points are configured to resist lateral slippage of the straps in order to laterally stabilize the load against which the user is working, and to accommodate knots having excellent holding strength.

User-manipulated exercise equipment of the type utilizing a weight-plate stack comprises a stack of weight plates, of which a user-selected portion moves as a unit along a pair of guide rods in response to an exercise movement by the user. The selected portion of the stack moves with virtually no cross-wise (i.e., lateral) shifting among the plates and virtually no friction between the moving portion of the stack and the guide rods because (1) a keystone bushing below the weight plate stack provides virtually error free alignment with the guide rods by setting the non-selected portion of the stack at a highly accurate home position that resets the moving stack if it has shifted laterally during movement, even if that shift is very slight, and (2) the guide rod holed in the weight plates carry bushings which align with the bushings of the adjacent weight plates to prevent the plates within the moving portion of the stack from shifting laterally with respect to each other and thereby contacting a guide rod. Preferably, the topmost weight plate in the moving portion of the stack carries bushings forming a smaller gap with the guide rods than the bushings of the remaining weight plates so that, at worst, only the topmost plate will contact a guide rod resulting in negligible friction.

An approach is described that combines distinct properties of a specialized porous nitrocellulose film (PNC) with quantum nanoparticles to create an improved assay and detection sensitivity, permitting the development of a camera-based imaging system for fluorescent detection of macromolecules in microarray format. The two properties of PNC that facilitate the approach are an extraordinarily high binding capacity and a newly observed internal scattering of light. Quantum nanoparticles complement these PNC properties by providing a higher level of emitted light than the fluorescent dyes in common microarray use. Overall, the approach allows for instrument cost savings, reduced imaging time, and the ability to remotely image.

Systems, methods, and apparatuses for microarray mixing are provided. In one embodiment, a system comprises a microarray having one or more vibration motors coupled thereto, and psuedo-random voltage signals are provided to the vibration motors to agitate the microarray. In this way, the size of a microarray mixer can be reduced while avoiding standing wave artifacts in the microarray background.

Methods and systems are provided for a lateral flow test device. In one example a lateral flow test device may include a housing comprising an upper first portion and a lower second portion, the lower second portion further including a planar surface, a nitrocellulose matrix strip, the strip disposed on the planar surface, and one or more ligand regions included in the strip, the ligand regions comprising one or more ligands. The strip may be formed from a liquid polymer mixture dispensed onto the planar surface via a dispensing device positioned vertically above the planar surface.
