Abstract: A sensing system that includes a cylindrical body including an internal flow channel that channels a first fluid therethrough, and a sampling chamber. The sampling chamber is in flow communication with an ambient environment. A venturi device is coupled within the cylindrical body, and the venturi device includes a high pressure portion and a low pressure portion. The low pressure portion is in flow communication with the sampling chamber. A valve is coupled within the cylindrical body and is positionable in at least a first position. A first flow channel is defined between the internal flow channel and the high pressure portion through the valve. The first flow channel channels the first fluid towards the high pressure portion such that the low pressure portion draws a second fluid into the sampling chamber from the ambient environment. A sensor assembly determines characteristics of the second fluid within the sampling chamber.

Abstract: The present invention is to provide a knife configured to receive a blade securely and safely in a handle thereof. The handle is assembled at least from first to third plates. The blade has one end pivotally connected between the second and third plates. The first plate has a switch groove extending in a front-rear direction and configured to position a locking switch.

Through the alternately layered layers of optical thin film, the transmittance of the lens for incident light in infrared ray band is reduced. Therefore, the infrared ray is mostly filtered without use of an additional infrared ray filter.

Abstract: A fixing apparatus comprises a base, a locking structure, an operating member, a first elastic member and a second elastic member. The base has an opening. The locking structure is movably disposed at the opening along a second direction. The operating member is movably disposed at the second surface along a first direction perpendicular to the second direction. The first elastic member is connected with the operating member and the base. The second elastic member is connected with the locking structure and the base. When the operating member moves along the first direction and compresses the first elastic member, the locking structure moves along the second direction by a resilient force of the second elastic member and exposes the opening. When the operating member moves along an opposite direction of the first direction, the locking structure moves along an opposite direction of the second direction and covers the opening.
