Abstract: A sleeve for securing a cryogenic vial includes a cylindrical body sized to receive a vial, the body including a longitudinal axis, a first end, and a second end. A plurality of deformable members are disposed near the first end of the body and are arranged to deform from a first configuration to a second configuration. Each deformable member is displaced outwardly relative to the longitudinal axis of the body in the second configuration.

Abstract: Step size can be used to slow or freeze the adaptive filter to improve AEC system performance, such as during double talk events. An AEC control system may be used to adjust the step size based on an echo-to-disturbance energy ratio (EDER). The algorithm adjusts the step size to lower the adaptation rate when the EDER is small (or the combination of the near signal and noise is large compared to the echo) and raise the adaptation rate when the EDER is large (echo is large compared to a combination of near signal and noise).

Abstract: A fuel system is provided for switching between two separate regulated pressures of a first fuel pump to a supply line. The supply line supplies both a second fuel pump of a high pressure fuel injection system and a fuel injector separate from the high pressure fuel injection system. The switchover can include multiple regulators, one of which is selectively disabled.

Abstract: System and techniques are described for applying selectable applications to process data packets an adaptive private network (APN). Methods to select application specific processing within a WAN ingress processing pipeline begin with receiving a packet from a local area network (LAN) in an adaptive private network (APN) WAN ingress processing stages. The received packet is identified to be separately processed by a selected application that is different than standard ingress processing. Packet processing flow is redirected to the selected application for application specific processing of the received packet in response to the packet being identified to be separately processed. The separately processed packet is returned to the standard ingress processing after completing the separate processing.

Abstract: Methods for determining the 3-D structures of proteins. Such a method includes incorporating a compound into a protein crystal such that the compound enhances the activity of the protein crystal to second harmonic generation, illuminating the protein crystal with a sufficiently intense light to cause second harmonic generation by the protein crystal, and detecting a second harmonic generation response produced by the protein crystal that is suitable for protein structure determination by diffraction analysis.

The base plate of the adaptor rail has an inboard flange extending along the longitudinal axis of the base plate. The inboard flange extends from the inboard portion of the base plate in a direction away from and below the base plate. The rail may include adaptor retainers axially spaced along the inboard flange. A truck bed cargo management assembly may include the rail and an adjustable clamp. A truck bed cargo management apparatus may include a truck bed accessory including a coupling arm to insert into truck bed adapter retainers and a retention member to secure the accessory with respect to the retainers.

Abstract: A method of laser welding a workpiece stack-up (10) that includes at least two overlapping steel workpieces (12, 14) comprises directing a laser beam (40) at a top surface (26) of the workpiece stack-up to form a keyhole (56) surrounded by a molten steel weld pool (58). The laser beam is conveyed along a predefined weld pattern that includes one or more nonlinear inner weld paths (66) and an enclosed outer peripheral weld path (68) surrounding the one or more nonlinear inner weld paths. During conveyance of the laser beam along the one or more nonlinear inner weld paths, the keyhole fully penetrates through the workpiece stack-up from the top surface of the stack-up to the bottom surface (28) of the stack-up. The method produces weld joints between the steel workpieces that do not have an intentionally imposed gap formed between their faying surfaces.

Abstract: A beam-scanning optical design is described for achieving up to kHz frame-rate optical imaging on multiple simultaneous data acquisition channels. In one embodiment, two fast-scan resonant mirrors direct the optical beam on a circuitous trajectory through the field of view, with the trajectory repeat-time given by the least common multiplier of the mirror periods. Dicing the raw time-domain data into sub-trajectories combined with model-based image reconstruction (MBIR) 3D in-painting algorithms allows for effective frame-rates much higher than the repeat time of the Lissajous trajectory. Because sub-trajectory and full-trajectory imaging are different methods of analyzing the same data, both high-frame rate images with relatively low resolution and low frame rate images with high resolution are simultaneously acquired.

Abstract: Techniques are described to automatically activate and deactivate standby backup paths in response to changing bandwidth requirements in an adaptive private network (APN). The APN is configured with one or more regular active wide area network (WAN) links in an active mode and an on-demand WAN link in a standby mode. The on-demand WAN link is activated to supplement the conduit bandwidth when an available bandwidth of the conduit falls below a pre-specified trigger bandwidth threshold and the conduit bandwidth usage exceeds a usage threshold of a bandwidth of the conduit that is being supplied by the active paths (BWC). The on-demand WAN link is deactivated to standby mode when an available bandwidth of the conduit is above the pre-specified trigger bandwidth threshold and the conduit bandwidth usage drops below the usage threshold of BWC. Techniques for adaptive and active bandwidth testing of WAN links in an APN are also described.

Abstract: A method for controlling the charging of one or more electric vehicles at one or more charging stations in a geographic locality includes determining if the charging event of an electric vehicle of the one or more electric vehicles increases a demand billing rate. The demand billing rate may be a cost per unit of energy in the locality. The method also includes charging the electric vehicle at the charging event such that the demand billing rate is not increased.
