Abstract: A system comprised of an apparatus and a test device is described. The test device and the apparatus are designed to interact to determine the presence or absence of an analyte of interest in a sample placed on the test device. The test device and apparatus interact to provide a timer feature for determining a test device specific adjustable cut-off value that is used to ascertain whether signal from a test line in the device corresponds to a positive or negative results, irrespective of the time elapsed since placement of sample on the test device. The adjustable cut-off value renders the system relatively insensitive to incubation time of the test device, where if the incubation time is shorter or longer than needed for accuracy of a test result, the analyzer will report an invalid result, thus preventing the reporting of an incorrect (false negative or false positive) result.

Abstract: A Handheld All-Terrain Chalker of the present invention is designed to create straight chalk lines on all types of surfaces. The Handheld All-Terrain Chalker works independent of the the surface in which the chalk lines are to be drawn and are unaffected by the variations of the surface. The Handheld All-Terrain Chalker includes a chalk hopper and a removable ergonomic handle. The chalk hopper is a semi-circular bucket having a storage container integrally formed with a dispenser. The storage container has an opening to allow the insertion of chalk. The dispenser is formed with a bottom having circular perforations or slotted openings to allow chalk to be dispensed to draw the chalk lines. To control the amount of chalk being dispensed and the width of the chalk line, a gasket or an adjustable chalk line plate is used to regulate the opening of the dispenser.
