Abstract: Methods and systems for pumping fluid through tubing are provided. Methods include orbiting one or more first rollers at multiple angular speeds around the periphery of a substantially circular first disk having a first radius with each first roller travelling at the same angular speed as the other first rollers, orbiting second rollers at a second angular speed around a substantially circular second disk having substantially the first radius, and increasing the pressure of fluid in tubing between one first roller and one second roller by causing the one or more first rollers to orbit at a first angular speed greater than the second angular speed so the one first roller moves along and fully compresses the tubing in a first section of the first disk, and simultaneously causing the one second roller to move along and fully compress the tubing in a first section of the second disk.

Abstract: Disclosed herein are electronic devices with a sensor configured to breakaway from an input button or input/output interface. In one example, the electronic device includes a button positioned within an opening of a chassis or housing. A sensor is in communication with the button, wherein the button is configured to contact the sensor in a first sensor position upon application of an activation force. At least one magnet is configured to retain the sensor in the first sensor position by a frictional or magnetic force. Additionally, the sensor is configured to move from the first sensor position to a second sensor position upon application of a force greater than the frictional or magnetic force and less than a sensor damage force. The activation force is less than the frictional or magnetic force, which is less than the sensor damage force.

Abstract: Disclosed is a two station system for a flow cytometer that includes a sample station and a wash station. During washing, the user has access to the sample station to insert a new sample. This increases the efficiency of the workflow process. Rotary clamps are used to automatically clamp the sample station and wash station to the system. A low volume pressurized cavity is used to bring the pressure of the sample to a desired pressure, which further increases productivity of the system. A transparent body is provided in the sample station so a user can view the sample during the sampling process. A backwash process is used to clean the sample injection tube and the sample uptake tube. In addition, the wash station is designed to rinse the outer surface of the sample uptake tube.

Abstract: A method includes impregnating a region of a glass sheet with a filler material in a liquid state. The glass sheet includes a plurality of glass soot particles. The filler material is solidified subsequent to the impregnating step to form a glass/filler composite region of the glass sheet.

Abstract: A manufacturing line includes a tape of green material that is directed through a furnace so that the furnace burns off organic binder material and then partially sinters the tape without the use of a setter board. Sintered articles resulting from the manufacturing line may be thin with relatively large surface areas; and, while substantially unpolished, have few sintering-induced surface defects. Tension may be applied to the partially sintered tape as it passes through a second furnace on the manufacturing line to shape resulting sintered articles.

Abstract: Disclosed is a system that can mix deionized water and concentrated sheath fluid to provide sheath fluid in a flow cytometer system having a desired concentration. Flow rates are low, which substantially match the flow rate of sheath fluid through the nozzle, so that turbulence and air bubbles are not formed in the sheath fluid. The available deionized water is then used for back flushing and removal of sample cells and deposited salts from the sheath fluid.

Abstract: Disclosed is an automated method and apparatus for automatically setting a drop delay period by detecting calibration particles in a waste stream. The drop delay is incremented over a series of drop delays and the number of calibration particles in the waste stream is detected for each drop delay. The drop delay is selected which has the least number of calibration particles in the waste stream.

Abstract: This disclosure provides egress and ingress for unmanned aerial vehicles (UAVs) from a fulfillment center (FC) to perform deliveries of products and return to the FC from such deliveries while providing minimal exposure of an interior of the FC. The UAV may be used to deliver the cargo from the FC to a destination, and then return to the FC to retrieve other cargo for another transport to another destination. In some embodiments, departing UAVs may be launched from the FC through a launch bay and returning UAVs may land upon a conveyance system to await being transported back into the FC. A flight coordinator may also provide assignments to the UAV based upon a current state of the UAV and other nearby UAVs and also based on a current order backlog of the FC and/or other considerations.

Abstract: This disclosure is directed to a detection and avoidance apparatus for an unmanned aerial vehicle (“UAV”) and systems, devices, and techniques pertaining to automated object detection and avoidance during UAV flight. The system may detect objects within the UAV's airspace through acoustic, visual, infrared, multispectral, hyperspectral, or object detectable signal emitted or reflected from an object. The system may identify the source of the object detectable signal by comparing features of the received signal with known sources signals in a database. The features may be, for example, a light arrangement or number of lights associated with the object. Furthermore, a trajectory envelope for the object may be determined based on characteristic performance parameters for the object such as cursing speed, maneuverability, etc. The UAV may determine an optimized flight plan based on the trajectory envelopes of detected objects within the UAV's airspace to avoid the detected objects.

Abstract: A fuel line assembly for an aircraft comprises a ferrule assembly comprising a ferrule affixed to an isolation tube, which may be directly affixed to a fuel tube or affixed to an extension tube, which in turn, is affixed to the fuel tube. The ferrule assembly provides electrostatic discharge protection and lightning protection as the isolation tube maintains a separation distance from the ferrule and fuel tube, both of which are made from metal. The isolation tube is made from a dielectric material, but which may have conductive particles added to aid in the dissipation of an electrostatic charge. The electrical resistance through the isolation tube has a lower limit to arrest the flow of the induced lightning current through the assembly. The amount of lightning protection afforded can be configured. The ferrule assembly components may be affixed by using thermo-welding, adhesive, or mechanical pressure.

Abstract: The subject matter described herein includes a modular and extensible approach to integrate noisy measurements from multiple heterogeneous sensors that yield either absolute or relative observations at different and varying time intervals, and to provide smooth and globally consistent estimates of position in real time for autonomous flight. We describe the development of the algorithms and software architecture for a new 1.9 kg MAV platform equipped with an IMU, laser scanner, stereo cameras, pressure altimeter, magnetometer, and a GPS receiver, in which the state estimation and control are performed onboard on an Intel NUC 3rd generation i3 processor. We illustrate the robustness of our framework in large-scale, indoor-outdoor autonomous aerial navigation experiments involving traversals of over 440 meters at average speeds of 1.5 m/s with winds around 10 mph while entering and exiting buildings.

Abstract: Disclosed is a sheath delivery system that uses a continuous flow of sheath fluid into a pressurized internal reservoir that substantially matches the outflow of sheath fluid through the nozzle of a flow cytometer. A substantially constant level of the sheath fluid is maintained. If the sheath fluid level falls below a desired level, or goes above a desired level, a dampened control system is used to reach the desired level. In addition, air pressure in the pressurized internal container is controlled so that an external sheath container can be removed and refilled with additional sheath fluid without stopping the sheath delivery system 100. Differences in pressure are detected by a droplet camera, which measures the droplet breakoff point to determine the pressure of the sheath fluid in the nozzle.
