An apparatus for detecting a puncture comprises a housing comprising a plurality of compartments. Each compartment comprises an opening for receiving a flow of air into the compartment. Each compartment also comprises a detection element mounted on an axle, the axle having a first end and a second end and being secured at said first end and said second end within the compartment. The detection element is rotatable about the axle and when a flow of air passes through the opening into the compartment, the detection element rotates around the axle in response to the flow of air.

A multi-control automatic faucet includes a faucet body, a manual valve core, a solenoid valve core, a water flow sensor, a main sensor switch, and a controller. The water flow sensor is configured to detect whether water flows through manual valve core. When there is water flowing through the manual valve core, the controller controls the main sensor switch to be inactive. When there is no water flowing through the manual valve core, the controller controls the faucet body to spray water out through the solenoid valve core. The multi-control automatic faucet has two control modes, namely, a manual control mode and a sensor control mode. It is convenient for users to use.

A covering device for protecting an anemometer engaged with an external frame on a moving body is provided. The covering device includes: a propeller protecting part including (1_1)-st and (1_2)-nd case units for protecting a propeller, wherein space created by combining the (1_1)-st and (1_2)-nd case units holds the propeller; a body protecting part including (2_1)-st and (2_2)-nd case units for protecting a main body and its vertical tail, wherein space created by combining the (2_1)-st and (2_2)-nd case units holds the main body and the vertical tail; and a supporting member protecting part including (3_1)-st and (3_2)-nd case units for protecting a supporting member, wherein space created by combining the (3_1)-st and (3_2)-nd case units holds the supporting member; wherein the (3_1)-st and (3_2)-nd case units engage the external frame, to allow all the case units to be fixed.

The present disclosure describes various systems and methods for measuring environmental parameters. In one embodiment, such as system comprises a pole that is equipped with various instruments (sensors) at various heights along the length of the pole. With such an instrumented pole, a local vertical profile of parameters that relate to wind conditions and air quality can be obtained. These parameters can include one or more of wind speed and direction, air turbulence, air temperature and humidity, concentrations of pollutant gases within the air, and concentrations of pollutant particles within the air. In some embodiments, the system can further measure other parameters that are relevant to the migration of the air and, therefore, the pollutants it contains.

An angle of attack sensor includes a vane assembly and a multi-piece faceplate adjacent the vane assembly. The faceplate includes a mounting plate having an opening and a heated chassis positioned adjacent the mounting plate and having a ring portion extending through the opening, the ring portion defining a ring-shaped deflector that surrounds the vane assembly and extends beyond an exterior surface of the mounting plate.

An air circulation indicator and method of use includes a rotatable fan blade, and a support structure for securing the rotatable fan blade substantially adjacent to a vent, such that air circulation through the vent rotates the fan blade, thereby indicating the air circulation through the vent. The support structure includes a housing assembly. The housing assembly is integrally formed with the vent. Alternatively, the housing assembly includes an attachment mechanism for attaching the housing assembly to the vent. The attachment mechanism includes a hook which removably attaches the housing assembly to the vent. In another alternative, the support structure includes a clip attachable to the vent, wherein the clip is removably attachable to the vent. The support structure includes a rotatable hub attached to the blade, and a rib extending from the hub to the vent for fixing the hub to the vent.
