Abstract: A fluid sample collection unit may include a pod configured to receive a plurality of assay pads and a metering stack. The metering stack defines a channel extending longitudinally between an inlet end and dispensing portions. In some instances, the dispensing portions are movable relative to the assay pads, but a support feature within the pod vertically spaces apart the dispensing portions from the assay pads when less than a threshold vertical pressure is applied. In one instance, the pod defines a collection volume, a dispensing volume, and a passage portion, the passage portion connecting the collection and dispensing volumes. The metering stack is at least partially received within the pod, with the inlet end being positioned at the collection volume, the dispensing portions positioned within the dispensing volume above the assay pads, and an air gap being formed within the passage portion around the metering stack.

Abstract: A traction tool is operable with fluid flow from coiled tubing for use in a wellbore. The traction tool includes a mandrel, a driver, at least one piston, and a motor. The driver is rotatably disposed on the mandrel and can be movable between retracted and extended conditions when the at least one piston is actuated. The driver in the extended condition is configured to engage inside the wellbore. The piston is adjacent to the driver and is actuated by the fluid flow from the mandrel. The motor is also actuated by the fluid flow from the mandrel. The motor imparts rotation to the piston and the drive, which can be supported by bearings on the tool's mandrel. Tracks on the driver arranged at an angle transverse to a longitudinal axis of the tool allow the rotating driver to spiral inside the wellbore and advance the traction tool.

Abstract: An aspect of the disclosure pertains to detecting a position of a blood pressure measurement device. An inflatable bladder of the blood pressure measurement device defines, at least in part, a pressurizable volume. The inflatable bladder may be inflated to pressurize a user's appendage and temporarily occlude blood flow in the user's appendage. A pump may initiate inflation of the inflatable bladder when one or more accelerometers and/or one or more proximity sensors determine that the blood pressure measurement device is within sufficient proximity or elevation to a user's heart and stationary.

Abstract: A device and method for estimating the frequency difference between antennas having asynchronized local oscillator references includes a frequency meter configured for connection with radio frequency signals from two antennas and configured to output a measured frequency difference between baseband filtered signals of two antennas. The frequency meter includes a phase meter, a quadrant transition, and a frequency meter counter. The phase meter receives in-phase and quadrature pairs of filtered signals and output a phase difference between the pairs. The quadrant transition state machine receives the phase difference, detects a quadrant associated with the phase difference, and detects a change between the detected quadrant and a previously detected quadrant. The frequency meter counter then accumulates the quadrant transitions and direction over a desired interval to establish a measure of the frequency difference between the two radio frequency signals input into phase meter.

The housing can support at least one aspect of a reusable system thereon.

Abstract: A traction tool is operable with fluid flow from on coiled tubing for use in a wellbore. The traction tool includes a mandrel, a driver, at least one piston, and a motor. The driver is rotatably disposed on the mandrel and can be movable between retracted and extended conditions when the at least one piston is actuated. The driver in the extended condition is configured to engage inside the wellbore. The piston is adjacent to the driver and is actuated by the fluid flow from the mandrel.

Tracks on the driver arranged at an angel transverse to a longitudinal axis of the tool allow the rotating driver to spiral inside the wellbore and advance the traction tool.

Abstract: Various embodiments are directed to group-based data storage systems configured for maintaining data exchanged between client devices within channel-specific shards each corresponding with one or more group-identifiers to provide group-based access to those channel-specific shards and for applying group-specific policies for data stored within those channel-specific shards. Membership of particular users within particular groups and within particular channels may be monitored such that access to particular channel shards may be controlled based on group-memberships of the users, and access to data stored within particular channel shards may be controlled based on channel-memberships of the users.
