Abstract: The present invention is directed to methods, compositions and devices useful for the detection and/or quantification of a microbial contaminant, including an endotoxin. In embodiments, cartridges are provided that suitably include dried compositions that are useful in absorbance-based assays and in combination with portable readers/devices.

Abstract: The present invention relates to a biochemical assay apparatus in which a sample processing device is controlled by a detection instrument through a series of linear and rotary actuations to execute a biochemical assay on a biological fluid sample.

Abstract: An attachable and extendable saw and methods for cutting objects with the attachable and extendable saw are provided. The attachable and extendable saw can include a blade housing coupled to a main body. The blade housing at least partially covers a saw blade and the extendable member can be configured to move the saw blade with or without the blade housing between a retracted position and an extended position relative to the main body. The extendable saw can also include means to drive the saw blade, means to drive the extendable member, and means for attaching the attachable and extendable saw to the objects to be cut. Saw blade height adjustment means, handles for ease of use, and eyelets for tethering are provided. The saw blade is attached to the attachable and extendable saw via pins and fasteners.

Abstract: The present invention is directed to systems and methods for cleaning a component inside a machine, such as an evaporator coil inside an air conditioner. A pump is connected to a controlling device. The pump is also connected to a metering device. The metering device is connected to one or more reservoirs. The metering device is also connected to one or more wands. Each wand is positioned inside a housing containing the component to spray cleaning solution, drawn from the reservoirs by the metering device, onto a face of the component. To perform the cleaning of the component, the controlling device disables the machine. The controlling device then activates the pump. The pump causes cleaning solution to be drawn from the one or more reservoirs into the metering device, which then transfers the cleaning solution into the wands. The controlling device then allows the machine to resume operation.

Abstract: Apparatus and methods for positioning one or more components relative to a work surface are provided. The apparatus can include a frame having a first support member extending therefrom. At least one extendable member can be disposed on the first support member. The extendable member can be adapted to move in a linear direction. At least one magnet can be disposed on the frame. The magnet can include at least one contact side that can be switchable between a magnetized state and a non-magnetized state.

Abstract: An apparatus for releasably attaching a pushing tool to one work piece such that a pushing force can be applied to a second work piece and allow alignment of the two work pieces for joining the work pieces together.

Abstract: A method of improving sales volume includes the steps of distributing redeemable offers to teams of shoppers wherein the shoppers are able to receive whatever basic discounts or other benefits that may be available to all shoppers, but also to receive a “kicker” benefit when the team achieves a specified purchasing objective such as a total of all sales to members of the team. Teams may compete for prizes or other benefits beyond those offered to individual teams.
