Abstract: Disclosed is a differential pressure volume flow air sampler that measures temperature in a collection cavity, differential pressure between the measured ambient pressure and air pressure in a collection cavity. These parameters are used to calculate the volume air flow across a collection disk using a processor which adjusts a blower to maintain a substantially constant volume air flow through said air sampler from the surrounding atmosphere.

Abstract: Systems, methods, and other embodiments associated with intelligent order routing are described. In one embodiment, a method includes receiving and parsing an electronic order. The example method may also include identifying a set of sourcing locations capable of sourcing an item for the electronic order. The example method may also include applying a set of weighted criteria to each sourcing location. The example method may also include generating ranks for each sourcing location. The example method may also include generating a set of control instructions within a data structure that identifies an item of the electronic order and a target sourcing location from the set of sourcing locations having a target rank exceeding a threshold. The example method may also include sending the data structure to a remote computer to cause the remote computer to initiate a transfer of the item from the target sourcing location to an item destination.

Abstract: A sampling device uses two ball valves that may be operated to take a sample while allowing flow to continue in a bypass path in a pressurized pipe. As one ball valve closes, it may capture a sample of liquid and gas that may be traveling in the pipe, then the sample may be discharged through a sampling outlet. The second ball valve may be operated simultaneously to open a bypass path while the first ball valve captures a sample. In some cases, the speed of actuation may be a function of the flow speed to capture an accurate sample. In other cases, the length of pipe from the sampling valve to the bypass junction may determine the effectiveness of the sample when actuation speed is relatively slow.

Abstract: A flow tester may use a low impedance flow meter to test a hole at a predetermined Reynolds number. The flow tester may be mounted to a robot so that testing may be fully automated. For example, the flow tester may be incorporated into a laser drilling workcell and used to test flow characteristics of a test coupon or workpiece to calibrate or verify the laser settings. Another example may be used for testing flow characteristics of a finished workpiece. The flow tester may have a testing tip that is compliant to form a seal against a workpiece, and the testing tip may be able to seal against angled, curved, or other surfaces. The flow tester may be capable of testing individual holes or groups of holes and determining an effective cross sectional area for the hole at the predetermined Reynolds number.
