According to one implementation, the transition interface may include a non-linear outlet taper. In another implementation, the transition interface may include a non-linear inlet taper and a non-liner outlet taper. In still other implementations, the water meter assembly may include a transition interface with different outlet and inlet tapers.

Abstract: A metering system uses an electronics assembly with a single transducer to determine flow rate. The meter assembly emits an ultrasonic beam from the transducer and splits the ultrasonic beam into a first partial beam and a second partial beam. The first partial beam is transmitted over a first path that returns to the electronics assembly, and the second partial beam is transmitted over a second path that returns to the electronics assembly. The first path goes over a first net distance of a measuring channel. The second path goes over a second net distance of the measuring channel. The meter assembly detects the return of the first partial beam and the second partial beam, measures a time difference between the return times, and determines a measurement of a fluid flow through the measuring channel based on the time difference.

Abstract: A reticle has a horizontal stadia line and a vertical stadia line. A plurality of elevation subtension markings having a thickness are connected to the vertical stadia line. A plurality of fine subtension markings are positioned along the horizontal stadia line. A plurality of coarse subtension markings are positioned along the horizontal stadia line. The thickness of the coarse subtension markings is greater than the thickness of the fine subtension markings. A Christmas tree dot pattern is provided below the horizontal stadia line with a hold point feature within a lower portion of the Christmas tree dot pattern.

Abstract: Upon determining a mobile object is approaching an ice layer above a body of water, a thermal image of the ice layer is obtained. The thermal image and ambient temperature data are input to a neural network that outputs a plurality of regions of the ice layer and respective estimated thicknesses for the regions. A classification for each region is determined based on its estimated thickness and the mobile object. The classification is one of preferred or nonpreferred. The classifications for the regions are output.

Abstract: A device may include a communication interface and a processor configured to determine that a first transmission task is scheduled and attempt to execute the first transmission task. The processor may also evaluate a metric associated with an effectiveness of the first transmission task. The processor may further modify or set at least one of a transmission interval or power level associated with a second transmission task based on evaluating the metric.

Abstract: A protective lens cover assembly is provided. A protective lens cover assembly comprises a body, a first lens cover and a second lens cover. The first and second lens covers are connected to the body. The first lens cover has a first set of securing structures and a second set of securing structures. The second lens cover also has a first set of securing structures and a second set of securing structures. The first set of securing structures of one of the first lens cover and second lens cover is configured to engage the second set of securing structures of the other of the first lens cover and second lens cover.

Abstract: A method and system are herein disclosed wherein a robot handles objects that are large, unwieldy, highly-deformable, or otherwise difficult to contain and carry. The robot is operated to navigate an environment and detect and classify objects using a sensing system. The robot determines the type, size and location of objects and classifies the objects based on detected attributes. Grabber pad arms and grabber pads move other objects out of the way and move the target object onto the shovel to be carried. The robot maneuvers objects into and out of a containment area comprising the shovel and grabber pad arms following a process optimized for the type of object to be transported. Large, unwieldy, highly deformable, or otherwise difficult to maneuver objects may be managed by the method disclosed herein.

Abstract: A viewing optic is disclosed. In one embodiment, the viewing optic is a rifle scope having a scope body, a movable optical element defining an optical axis connected to the scope body, a turret and a zero point adjustment subassembly. The turret includes a turret screw, a turret chassis subassembly and a turret cap. The turret screw defines a screw axis and is operably connected to the optical element for adjusting the optical axis in response to rotation of the screw. The turret cap at least partially overlaps the turret chassis subassembly. The zero point adjustment subassembly includes a zero cap connected to the turret screw and a locking mechanism. The locking mechanism releasably secures the zero cap and the turret. The zero point adjustment subassembly permits adjustment of the zero point without the use of tools.

Abstract: A riflescope with a scope body has a movable optical element defining an optical axis connected to the scope body.

Abstract: Systems and methods described herein provide a pilot-operated oscillating valve including a diaphragm. The valve is configured such that when the diaphragm is in a closed position, pressure of a fluid supply opens the valve, and when the diaphragm is in an open position, the pressure of the fluid closes the valve. The oscillating valve may further include an actuator that can cause the valve to be arrested selectively in the open position or the closed position depending on a state of the actuator. The state of the actuator is switchable with a small expenditure of energy, enabling an extended duty cycle for a battery or other power source associated with the actuator. In some implementations, energy from the oscillating movement of the diaphragm may be captured to recharge the battery for the actuator.
