Abstract: An aseptic liquid cryogen dosing head has a liquid cryogen reservoir in communication with a dosing outlet. An electromagnetic actuator is attached to an upper end of a dosing valve stem and is operable to move the dosing valve stem to open and close the dosing outlet. An air-tight seal extends about the dosing valve stem and separates the liquid cryogen reservoir from a cavity between the seal and the electromagnetic actuator. A controller is operable to perform a head leakage test, including pressurizing the cavity with a pressure higher than a pressure within the reservoir, to check for leakage past the seal; and pressurizing the reservoir to check for leakage from the liquid cryogen reservoir.

Abstract: Disclosed is an approach to differentiating between different particle types in samples flowing through microfluidics chips. A sample may have an initial proportion of a first cell type to a second cell type. An illuminating light source may emit a coherent light at the sample, and light leaving the chip in a first direction may be detected using a first light detector, and light leaving the chip in a second direction (e.g., orthogonal to the first direction) may be detected using a second light detector. The detected light may be fluorescence. An orientational feature of a plurality of cells in the sample may be determined based on the light detected by the detectors. Based on the orientational features and the detected light, a biasing operation may be performed for each cell in the sample to obtain a modified proportion of cell types in the sample.

Abstract: A robot configured for pipe handling. The robot may include an articulated arm controllable by a controller and an end effector arranged at an end of the articulated arm. The articulated arm may include two pipe engaging jaws, each jaw having an inner contour configured for engaging a pipe section. At least one of the jaws may be a fixed jaw. The end effector may be configured to restrict radial movement of the pipe section while permitting axial movement. The inner contours of the two jaws may be arranged on different planes in some embodiments. The inner contours May additionally be concave in opposing directions. The articulated arm may be configured to pivot the end effector about a central axis extending between, and parallel to, the planes of the inner contours. In some embodiments, one or both jaws may be actuatable.

Abstract: In implementation of techniques for template-based behaviors in machine learning, a computing device implements a template system to receive a digital video and data executable to generate animated content. The template system determines a location within a frame of the digital video to place the animated content using a machine learning model. The template system then renders the animated content within the frame of the digital video at the location determined by the machine learning model. The template system then displays the rendered animated content within the frame of the digital video in a user interface.

Abstract: A framework for generating and presenting verbal command suggestions to facilitate discoverability of commands capable of being understood and support users exploring available commands. A target associated with a direct-manipulation input is received from a user via a multimodal user interface. A set of operations relevant to the target is selected and verbal command suggestions relevant to the selected set of operations and the determined target are generated. At least a portion of the generated verbal command suggestions is provided for presentation in association with the multimodal user interface in one of three interface variants: one that presents command suggestions as a list, one that presents command suggestions using contextual overlay windows, and one that presents command suggestions embedded within the interface. Each of the proposed interface variants facilitates user awareness of verbal commands that are capable of being executed and teaches users how available verbal commands can be invoked.

Abstract: The eye imaging system for producing images with reduced speckle artifacts may comprise a laser diode for providing a beam of radiation to the eye; a detector for collecting light returning from the eye and generating output signals in response thereto, the detector having a sensor integration time; a driver circuit for applying a modulated drive signal to the laser diode, the modulated drive signal inducing a spectral broadening of the beam of radiation during the sensor integration time. The laser diode may be a single-mode laser designed to operate at a fixed current and wavelength. The drive signal may be modulated by shaping a drive current pulse. The drive signal may be modulated by imposing an RF modulation on a drive current pulse. The drive signal may be further modulated by shaping a drive current pulse.
