Abstract:
A memory comprises a row of bit cells, including a first plurality of bit cells and a second plurality of bit cells. A first word line segment driver is connected to the first plurality of bits cells. A second word line segment driver is connected to the second plurality of bits cells. The first and second word line segment drivers are selectively operable for activating one of the first and second pluralities of bit cells at a time to the exclusion of the other plurality of bit cells. A shared sense amplifier is coupled to at least one of the first plurality of bit cells and at least one of the second plurality of bit cells. The shared sense amplifier is configured to receive signals from whichever of the one first or second bit cell is activated by its respective word line segment driver at a given time.

A disk structure is disposed in an optical tweezers device including a light source for producing incident laser light. The disk structure includes a first substrate, a second substrate and a reflective layer. The second substrate is disposed with respect to the first substrate. One of the first substrate and the second substrate has at least one flow path. The reflective layer, which is adhered to the second substrate, is disposed between the first substrate and the second substrate.

Abstract:
A continuous testing device for testing the concentration of a target object in a fluid is provided. The continuous testing device includes a first chip, a signal source and a second chip. The first chip includes a separating unit and a reacting unit. The separating unit separates the target object from a non-target object in the fluid.
