Abstract:
A method, system and apparatus for imaging an oral cavity of a subject include a bracket comprising a mouthpiece and a camera mount. The mouthpiece has upper and lower bite guides disposed on a posterior side and separated by an opening through the mouthpiece. The bite guides are spaced apart so a subject biting on the guides opens the oral cavity to inspection through the opening. The mount is disposed on an anterior side of the mouthpiece; and has a flange to engage and slide along the opening and an optical path for light to pass through the mount and mouthpiece. A clip on an anterior side of the mount is configured to removeably hold a camera to record light passing through the optical path from the posterior side of the mount. In one embodiment, the camera is a programmable cell phone with digital camera.

Abstract:
A method of manufacture and assembly of multiwell plates employing targeted radiation at an interface in order to achieve bonding is disclosed. The method accommodates glass and polymer attachment as well as polymer to polymer attachment. Resultant plates have unique flatness and optical properties.
Abstract:
A rucksack comprises a sack (1), a carrying harness (11) and a waistbelt (12). The rucksack has an external frame member comprising a U-shaped hoop (20) which is connected by its free ends to the waistbelt (12) and extends around the side walls (4) and front wall (2) of the rucksack (1). Compression straps (25, 28) are connected between the hoop (20) and the rucksack such that the hoop (20) may be adjusted relative to the rucksack (1). The hoop (20) is held in a sleeve (21) sewn to the walls (2, 4) of the rucksack (1).
Abstract:
A multiwell plate device is provided having a frame, a substantially flat substrate and a multiwell structure supported by the substrate. The multiwell structure includes multiple bottomless wells formed therein. The substrate is supported by the frame and may be processed by an automated arrayer or instrument that is used to print or spot arrays in a pattern on a reaction surface of the substrate. Thereafter, the multiwell structure may be engaged with the substrate and the multiwell structure and substrate may be engaged with the frame in an upright orientation. For scanning or other analysis, the multiwell structure and substrate may be disengaged from the frame, inverted 180°, and then reengaged with the frame in the inverted orientation.
Abstract:
In accordance with one aspect of the present disclose, a fluid compressor for compressing a fluid is disclosed. The fluid compressor has a frame and a piston assembly. The piston assembly has a compression chamber connected to the frame, and the compression chamber includes a movable piston inside of the compression chamber along with a connection rod of a smaller transverse dimension than the diameter of the piston connected to the piston at a first end of the connection rod. The fluid compressor further has a pivot point located on the frame, and a lever connected to the pivot point. The lever has a short end and a long end on opposite sides of the pivot point, and the short end is connected to a second end of the connection rod. Further included is a lifting device for raising and lowering the lever.
Abstract:
An apparatus for and method of recycling the edge portion of a chopped strand mat are disclosed. The method includes the steps of trimming an edge portion of the chopped strand mat, transporting the edge portion to a shredder assembly, and shredding the edge portion into individual strands or filaments. The separated strands are introduced with new chopped strands into the chopped strand mat forming process. The apparatus for recycling the edge portion of the mat includes a shredder assembly for separating the edge portion into individual strands. The shredder assembly includes two pairs of rollers that engage the trimmed edge portion. The first and second pairs of rollers are driven at first and second rotational speeds, respectively. Preferably, the second speed is greater than the first speed. The mat is pinched between each pair of rollers and is thereby placed under tension due to the different rotational speeds. The tension applied to the mat breaks the resin bond between the strands in the mat, separating the mat into individual strands on the downstream side of the second pair of rollers. The individual strands are then transported to a forming hood of the chopped strand mat forming apparatus and introduced into the chopped strand mat manufacturing process.
