A method and apparatus for characterizing the response of an electronic stethoscope. The sensor of the electronic stethoscope is held in contact with a test surface of a phantom. A shaker, which is coupled to a stinger rod that extends inside the phantom, is driven to produce internal vibrations in the phantom. Surface motion of the test surface of the phantom is measured using a surface accelerometer coupled to the test surface. Vibrations from the phantom are detected and an electric signal based on the detected vibrations is generated with the electronic stethoscope. A surface transfer function is calculated based on the measured surface motion and the electric signal to characterize the response of the electronic stethoscope.

A coupling for attaching a support tube of a sports equipment carrier frame to a hitch mount, securely held to a mounting stinger received in a receiving type hitch of a transporting vehicle. The hitch mount includes a slot for sliding engagement with a lock pin held to the support tube by a bracket. A latch, pivotally mounted in the hitch mount, moves between open and closed positions. Its open position allows the lock pin to move into the slot to establish a suitable position for joining the support tube to the hitch mount. When the latch moves to its closed position, it captures the lock pin to secure the connection between the hitch mount and the support tube.

The invention provides a coupler and a method for installing an instrumentation line, such as fiber optic cable, into a wellbore. The coupler places upper and lower instrumentation lines in communication with one another downhole to form a single line. The apparatus comprises a landing tool and a stinger that lands on the landing tool, thereby placing the upper and the lower instrumentation lines in communication. The landing tool is run into the wellbore at the lower end of a tubular, such as production tubing. The upper instrumentation line affixes to the tubing and landing tool and extends to the surface. The lower instrumentation line affixes along the stinger. In this manner, the lower instrumentation line may be installed after expansion of a well screen or liner and may be later removed from the wellbore prior to well workover procedures without pulling the production string.
