5 results about "Flexible collar" patented technology

A covering is provided to protect nozzles from outdoor elements while allowing the nozzle to discharge fluid when needed. The covering includes a water way portion with a cap, a lock ring, a clamp, and a flexible collar, and may also include a body cover attached to the water way portion and extending over the body of the nozzle. The cap is configured to cover the water way of the nozzle and is attached such that when pressure is applied from the water way, the cap is released allowing water to flow from the nozzle. The cap may then be reattached to the collar when the nozzle is not is use. In this way, the cover protects and covers fire nozzles up to the moment that the equipment is activated.

The invention discloses a flow velocity sensor assembly, an ecological flow measurement device and a measurement method, and belongs to the technical field of measurement, and the flow velocity sensor assembly comprises a shell which comprises an upper shell part, a lower shell part and a flexible lantern ring, the lower shell part is connected with a balancing weight, and the upper shell part is connected with a sling; the flow velocity sensor main body is arranged in the upper shell part, and two ends of the flow velocity sensor main body are respectively connected with a water inlet pipe and a water outlet pipe; the empennage is arranged outside the shell and connected with the water outlet pipe; and the proximity sensor is arranged in the shell and is provided with a main body part and a sensing end, and the sensing end is arranged on the upper side of the balancing weight. The ecological flow measuring device comprises a supporting frame, a hanging seat, a lifting assembly, a transverse moving assembly and a flow velocity sensor assembly. The ecological flow measurement method uses the ecological flow measurement device to measure the ecological flow. A worker can use the lifting assembly and the transverse moving assembly to control transverse moving and lifting of the flow velocity sensor assembly on a water cross section, and the ecological flow can be accurately measured.

A collar-mounted locator sensor and stimulation unit (101) comprise a body (110). Quick-mount fastening clips (112-115) extend from the upper and lower lateral edges of the body, bend at a 90-degree angle toward the center, and extend a short distance toward each other before terminating. A flexible collar (40) is clamped between the quick-mount clips and then released to expand within the space between the fastening clips and the ends of the body. A generally flat stimulation unit (127, 130) and an impedance-based fur detector (126) protect the animal from harmful stimulation. At least one sensory stimulator is configured to provide at least one auditory, kinesthetic, or visual stimulation in response to the output signal from a locator sensor.An electrode cover (150), in a first deactivation position, electrically isolates the stimulation electrodes (132a-f) from the animal, and in a second activation position allows electrical connection between the stimulation electrodes and the animal's fur.

Apparatus and system aspects for camera lens flexure collars are disclosed herein. An aspect includes an inner wall having one or more internal protrusions, an outer wall having one or more openings, a cam located between the inner wall and the outer wall, an actuation arm coupled to the cam and extending through the one or more openings of the outer wall, and two flexure members. The aspects are operated by manipulation of the actuation arm, where manipulation of the actuation arm moves the cam and generates a force through the one or more internal protrusions of the inner wall, thereby causing the inner wall to move in an axial direction within the stress limitation of the two flexure members. In this regard, movement of the inner wall in the axial direction can focus one or more camera lenses.
