A damper assembly is configured for deployment in an existing forced air duct that supplies conditioned air through a register boot to a vent cover secured relative to the register boot. The damper assembly includes a damper frame having an at least substantially obround shaped frame periphery and a damper blade having an at least substantially obround shaped blade periphery. A damper insert arm is biased into a deployment configuration in which the damper insert arm is at least substantially perpendicular to the damper frame and is movable into an operational configuration in which the damper insert arm is at least substantially parallel with the damper frame. A latch is configured to releasably engage the damper insert arm in order to hold the damper insert arm in the deployment configuration.

A directly-controlled hydraulic directional valve includes a housing, control piston, first and second springs, double-stroke solenoid, spring plate, adjustment device, and electronics. The piston is longitudinally displaceable in a bore in the housing, either directly or via a control sleeve. The springs are positioned in a region of an end of the piston remote from the solenoid. One end of each spring is supported on the spring plate, which is clamped between the springs and the piston. The other end of the first spring is fixed to the housing, and the other end of the second spring is fixed to the adjustment device. The first spring exerts a force on the piston in a first direction, and the second spring exerts a force on the piston in a second opposite direction, so as to bias the piston into a preferred position. The solenoid is mounted on a side of the housing, and is operable to move the piston out from the preferred position in opposite directions proportional to an electric current from the electronics, such that the piston moves to the preferred position in response to each of non-actuation of the solenoid and a fault in the electronics. The adjustment device is operable to alter a position of the other end of the second spring to adjust the preferred position of the piston.

In one embodiment, a multi-purpose sensor may couple to a machine operating in an industrial environment and include numerous sensors disposed within the multi-purpose sensor to acquire sets of data associated with the machine or an environment surrounding the machine. A first portion of the sets of data may include historical sensor measurements over time for each of the sensors, and a second portion of the sets of data may include sensor measurements subsequent to when the first portion is acquired for each of the sensors. A processor of the multi-purpose sensor may determine a baseline collective signature based on the first portion, determine a subsequent collective signature based on the second portion, determine whether the collective signatures vary, and generate signals when a variance exists. The signals may cause a computing device, a cloud-based computing system, and/or a control/monitoring device to perform various actions.

The present technology relates to an automatically locking, releasable, safety knob assembly for a stove. The assembly includes a base with a locking notch. An adapter mates with the stove's valve stem and has a head, a tubular middle section, and an adapter base with a central aperture for receiving the valve stem. The knob includes a housing with a housing disk covering the base, an arm movement channel aligned with the locking notch in the locked configuration, and a central aperture for receiving the adapter head. The assembly further includes a sub-assembly with a slidable button allowing free rotation of the knob in the unlocked configuration, an automatic locking arm biased with the slidable button, and engagement with the button causing the arm to disengage from the locking notch and move in the arm movement channel, enabling the knob to freely rotate and rotate the valve stem.

A system and method for monitoring an underground valve is provided. The system includes a valve having an actuator operable to open and close the valve. The system includes a first housing having a recess, the recess being sized to fit at least partially over the actuator. A second housing is removably coupled to the first housing, the second housing having a hollow interior disposed to have an open end enclosed by the first housing, the second housing further having a handle feature opposite the open end. A sensor is disposed in the hollow interior, the sensor generating a first signal in operation in response to a movement of the second housing.
