Abstract: Certain embodiments described herein are directed to chromatography systems that include a microfluidic device. The microfluidic device can be fluidically coupled to a switching valve to provide for selective control of fluid flow in the chromatography system. In some examples, the microfluidic device may include a charging chamber, a bypass restrictor or other features that can provide for added control of the fluid flow in the system. Methods of using the devices and methods of calculating lengths and diameters to provide a desired flow rate are also described.

Abstract: An architecture which allows real-time video editing using a 2D/3D graphics engine. This architecture comprises input and output buffers. It receives video streams from either compressed sources of data or non compressed sources of data. This architecture allows a flexible upgrade of the video effects using software plug ins.

Abstract: An apparatus is configured for inclusion in an arrow. In one embodiment, the apparatus includes a sensor configured to provide data concerning one or more flight characteristics of the arrow in flight and a communication link coupled to the sensor, the communication link configured to communicate the data to a device external to the arrow.

Abstract: A device for sustaining a plasma in a torch is provided. In certain examples, the device comprises a first electrode configured to couple to a power source and constructed and arranged to provide a loop current along a radial plane of the torch. In some examples, the radial plane of the torch is substantially perpendicular to a longitudinal axis of the torch.

Abstract: An apparatus is configured for inclusion in an arrow, where the apparatus includes a device configured to provide feedback to a user concerning the arrow shot from a bow, and a processor coupled to the device, the processor configured to control an operation of the device at least during a flight of the arrow.
