Abstract: An apparatus includes a housing, a sample carrier device. The sample carrier device includes samples and is mounted in the housing such that the samples are external to the housing. The apparatus further includes a sample cover mounted to the housing such that the sample cover and the housing enclose the sample carrier device. The apparatus further includes a sensor directed to the sample carrier device. The apparatus further includes a processor and a memory device storing instructions executable by the processor to initiate removal of the sample cover from the sample carrier device. The instructions are further executable by the processor to initiate capture of data by the sensor.

Abstract: An application for a system and method for generating browns gas (mixture of oxygen and hydrogen) from a direct current power source is disclosed. The browns gas is mixed with fossil fuels such as gasoline, ethanol and diesel before combustion in a combustion engine. In such, the efficiency of the combustion engine is improved while reducing emissions of pollutants. A unique grid arrangement is immersed in an electrolyte for generating browns gas. The grid assembly includes conductive plates that are insulated and interspersed between positively biased plates and negatively biased plates, thereby improving the efficiency of the electrolysis.

Abstract: A vending machine with a frame in which there are numerous pivoting shelves, each shelf having a tang which extends through a hole in the frame, each tang having a tab positioned to frictionally interact with a side of the hole to keep the shelf in a generally horizontal position until the tab is forced out of the frictional interaction by a ratchet slide which travels vertically up a ratchet column disposed next to the frame. The ratchet column causes the slide to ratchet upward by moving a face of the column up and down vertically, causing grooves on the column to lift the slide. Each movement of the face up and back down causes the slide to ratchet to a position one hole higher, forcing the tang out of frictional interaction with the hole wall which causes the shelf to pivot and drop its contents into an accessible receptacle at the bottom of the machine.
