  • Patent number: 9735303
    Abstract: A color light field imaging sensor array for use as a lensless imaging camera, tactile or proximate gesture user interface, image display, or combination. Each sensor array pixel comprises groups of at least three LEDs, OLEDs, or similar devices having differing emission color wavelengths configured to provide light amplitude measurement signals. For each pixel, a first output signal is produced by subtracting a function of the light amplitude measurement signal from an LED of a mid-value color wavelength from a function of a light amplitude measurement signal from an LED of a higher-value color wavelength. A second output signal is produced by subtracting a function of a light amplitude measurement signal from lower-value color wavelength LED from a function of the light amplitude measurement signal obtained from mid-value color wavelength LED. A third output signal is produced from function of light amplitude measurement signal associated with lowest-value color wavelength LED.

  • Patent number: 9724694
    Abstract: An article of laboratory glassware for directing the flow of chemical materials is described. The article includes a glass manifold having a plurality of input ports and at least one output port, and a plurality of stopcocks. Each stopcock has an inlet port and an outlet port connected by a passageway through the plug. Each of the stopcock output ports is connected to one of the manifold input ports, and each stopcock input port is connected with one end of a hollow glass tube, and the other end of the hollow glass tube is connected to a ground glass joint. The output ports of the manifold are terminated to a ground glass joint. Each plug is rotationally coupled to a planetary gear arrangement operated by a stepper or electrical motor, and rotational position can be sensed by a sensor. The rotation of each rotating plug is controlled by a computer.

  • Publication number: 20140274814
    Abstract: A removable microfluidics structure comprising at least one actuated fluid delivery element, wherein the actuated fluid delivery element is a pump element of a valve element configured to control fluid delivery to or from a removable media detachably coupled with the removable microfluidics structure based on an actuation force. The actuation force is an external actuation force or an internal actuation force. The removable microfluidics structure may include an electromechnical actuator for providing the actuation force, such as a solenoid, a solenoid with an ferromagnetic core or a piezoelectric actuator. The removable microfluidics structure may further include a coupling mechanism for detachably coupling the removable microfluidics structure with the removable media, such as a cell array, such that when the microfluidics structure couples with the removable media, the microfluidics structure controls fluid delivery to or from a cell of the cell array.
