  • Patent number: 10033910
    Abstract: The present approach relates to the synchronization of frame acquisition by a camera with an external event or trigger despite the camera lacking external control or synchronization capabilities. For example, inexpensive and/or consumer grade camera typically lack a control interface to explicitly synchronize with an external trigger event or external device. The present approach allows synchronization of such a camera lacking external synchronization capabilities with an external event or device.

  • Patent number: 9714447
    Abstract: The present disclosure relates to characterization of biological samples by amplification detection in a porous substrate. By way of example, a porous substrate may include amplification reagents configured to provide a signal when released during amplification. When a sample is applied, amplification occurs as a wavefront from the application point, and the time that the wavefront reaches a distance on the porous substrate is related to an initial concentration of the sample applied. By detecting the distance traveled by the amplification products at one or more time points, an initial concentration of the sample may be estimated.

  • Publication number: 20170153223
    Abstract: A device and/or methodology are described that include a mechanism for separating erythrocytes from other constituents of blood and for purifying leukocytes from blood. The separation and purification aspects may be provided in separate components or within the same component. The separation aspect assists in separating erythrocytes (red blood cells) from other cells in blood, such as by aggregation of the red blood cells. A suitable aggregation device or device component uses chambers with at least one small dimension (e.g., a microfluidic chip) to control the interaction of the blood with a solution containing a high molecular weight polymer (e.g., dextran) to achieve separation.
