Abstract: Linear peristaltic pumps for use with fluidic cartridges. An apparatus includes a reagent cartridge configured to be received within a cartridge receptacle of a system. The reagent cartridge includes a reagent reservoir and a body including a surface that forms depressions. Each depression has a fluid inlet and a fluid outlet and is fluidly coupled to at least one other depression. The reagent cartridge also includes a deformable material coupled to the surface of the body and includes portions. Each portion covers one of the depressions to define chambers. The portions of the deformable material are movable relative to the depressions between a first position outside of a dimensional envelope of the body and a second position within the dimensional envelope of the body.

Abstract: An analog signal measurement apparatus and system that utilize light optics to trigger button input commands when the button is pressed or activated. A light beam from an infrared light emitting diode is adapted to enable users to operate electronic equipment with limited physical interaction with the equipment surfaces. Embodiments of the invention utilize a non-contact analog signal measurement that occurs with a beam of light from an infrared emitting diode is directed inside a hollow tube towards a piston that moves in and out of the tube. The beam is reflected towards an infrared receiving diode, which connects to an analog sensor that calculates the delay and beam intensity in order to determine the proximity of the piston. In embodiments, the piston is a spring-loaded structure with a leading centrally placed rod that does not obstruct the beam of light and is connected to the analog trigger button on the other end which recedes into the hollow tube when the user presses a trigger button.

Abstract: A platform or mat for exercising and dancing that is lightweight, has non-slip features and can be folded up for storage. The platform allows a user to determine foot position without having to look down at the platform thus allowing the user to watch a display screen while exercising or dancing. The platform includes tactile indicia molded that foot placement is determined by feel by the user's foot touching the tactile indicia. The material used to make the platform surface includes ethylene vinyl acetate. The platform includes electrically conductive switches that are activated by a force from the user's foot on a segment while exercising or dancing. Placing a user's foot on a segment communicates signals about the user's foot placement to a control device. The control device includes popular video game player devices and computers and includes the use of a display screen.
