Abstract: A chamber device for analyzing living cell(s). The chamber device includes a base and a lid that when reversibly pressed closed create a chamber. The base is configured with an optically transparent well to contain at least one cell. The lid has a breadth greater than the base and is configured to contain at least one sensor. The lid is further configured with a lip that when pressed between the lid and the base creates an impermeable seal. The base and the lid are configured so that, when closed and in use, the sensor remains spatially apart from the at least one cell.

Abstract: Systems and methods for growing photosynthetic cells that may be used to produce a biomass. The systems and methods recycle liquid and can produce a high cell concentration harvested biomass.

Abstract: The present invention is directed to devices having wheels, and more specifically, a method and device for making the wheels readily detachable and interchangeable by users. The removable wheel system comprises a removable axle, a wheel, an optional shield, and a hangar to be assembled in connection with a skateboard. The present invention provides a wheel and hangar using a removable axle for a removable wheel system that is easily removable, replaceable, durable, and protectable against dust accumulation while providing the strength necessary to withstand the rigors and stresses imposed on the system during use.
