A collection device for a biological sample to capture target compounds such as viruses or other pathogens or particles for testing from within the sample and move the captured target compound to a separate chamber for subsequent processing. The collection device can include an openable substance blister including capture particles located in a cup interior. Capture particles can attract and bind the target compounds from the sample. An extraction tube extracts any nucleic acid from the target compound for storage or subsequent amplification and testing to confirm presence of known microorganisms. The extraction tube can comprise a heat-deformable material and can be connected to a microfluidic cartridge for further processing of nucleic acid including, amplification and detection. The microfluidic cartridge includes valves and a plurality of chambers for amplification.

Method and system for sample collection, storage, preparation and detection

A method to extract, amplify and separate nucleic acid in a microfluidic device having a plurality of chambers and channels can include a) introducing cells having nucleic acid to a first chamber of the microfluidic device and subjecting the cells in the first chamber to conditions that lyse the cells. The method can further include b) subjecting the first chamber to centrifugal force, thereby allowing the lysate or a portion thereof having nucleic acid to be distributed to a second chamber through a first channel in the microfluidic device. The method can also include c) combining the lysate or the portion thereof and reagents for amplification of the nucleic acid, thereby providing a second mixture. The method can also include d) subjecting the second chamber to centrifugal force, thereby allowing gas to be expelled from the second mixture.

Devices and methods for extraction, separation and thermocycling

A sizing apparatus has input and output ends and a sampling window therebetween. Sizing means determines the size of each item passing through the sampling window. Singulating means arranges the items in a line and delivers them sequentially at the input end of the sizing apparatus. A lower conveyor belt extends through the sizing apparatus from the input end through the sampling window to the output end. The lower conveyor belt is translated at a speed sufficient to receive, transport, and maintain the items in sequential fashion. A flexible upper stabilizer belt is arranged above and generally in alignment with the lower conveyor belt, and is driven to match the speed of the lower conveyor belt. The upper stabilizer belt is suspended so as to engage the items incoming from said singulating means and to maintain loose contact with them until the items have passed through the sampling window.

Agricultural sizer with item stabilizer belt

A conveyor belt comprised of a plurality of rigid, elongated bars arranged in parallel, spaced relation. The ends of each bar are connected to parallel, lateral belts, to support the bars and maintain their registration. Each bar has a plurality of elements, extending from either side of the bar. Elements on one side of a bar arranged in interdigitized relation with respect to adjacent elements extending from an adjacent bar. Rollers are provided within of the arcuate ends of the lateral belts, with at least one roller being driven. The rollers may be smooth or toothed, to engage the undersides of the lateral belts. The belt may be endless, or assembled from one or more belt segments. Two or more belts may be combined laterally, to increase the width of the conveyor belt.

Bar belt with interdigitized elements

The present invention provides a kit for attaching a manually operated wheelchair to a motorized scooter having a seating apparatus and supporting structure and a floor, comprising: (a) a motorized scooter attachment angle iron, wherein the angle iron comprises: (i) a vertical wall; and (ii) a horizontal wall, the horizontal wall forming approximately a right angle to the vertical wall, wherein the horizontal wall has at least two embedded elongated slots; (b) an angle iron attachment adjustable bar, wherein the adjustable bar comprises (i) a left elbow shaped tubular segment having a horizontally oriented bottom end and a vertically oriented top end; (ii) a right elbow shaped tubular segment having a horizontally oriented bottom end and a vertically oriented top end; and (iii) a straight middle tubular segment having a diameter larger than the left segment and the right segment, so as to permit the left segment to insert into a left end of the middle tubular segment and so as to permit the right segment to insert into a right end of the middle tubular segment; and (c) a pair of tubular adapters, wherein each adapter comprises (i) an elbow connecting bottom end, capable of attaching to the vertically oriented top end; and (ii) a concave top end, wherein the concave top end is generally perpendicular to the elbow connecting bottom end and wherein the concave top end is open on top.

Motorized scooter wheelchair attachment device

A method of attaching a manually operated wheelchair to a motorized scooter using an angle iron, an adjustable bar that has a left segment, a middle segment, a right segment and a pair of adapters. A user slides the middle segment over the left and right segments, and inserts screws into left and right holes in the middle segment and aligned holes in the left and right segments. The user then screws the adapters onto upper ends of the left and right segments and snaps them into position on the underside of the wheelchair. Next, the user removes the seating apparatus from the scooter, fastens the angle iron to the floor of the scooter by inserting a pair of bolts through the slots in the angle iron and tightening the bolts with a pair of matching nuts, and places the bar squarely against the angle iron.

Roller module

An apparatus and a method for sizing and sorting articles in an article stream. A scanning station includes a plurality of laser line beam generators and a linear array including a plurality of photo detectors. A first group of generators and detectors is horizontally oriented, and second group is vertically oriented. The area between the generators and the detectors defines an exposure window through which the articles are passed. Each line beam generator has a respective cylindrical lens for collimating its output across the exposure window. The output information is sampled, digitized, stored, and analyzed. Computer-based determinations are made regarding the size, configuration, and weight of the articles. Articles determined to have predetermined physical characteristics are selectively removed from the article stream, and directed to diverting conveyors carrying articles having like characteristics.
