摘要:
A vehicle cylinder head coolant passage inspection device and a method for inspecting vehicle cylinder head coolant passages therewith. A device and method of the present invention can be used to detect blockages present within such coolant passages. A device and method of the present invention uses one or more fiber-optic probes that can both emit and receive light. The probe(s) are used with a sensor that can register light reflected by a blockage and received by a probe(s) while in a coolant passage. Reflected light readings registered by the sensor can be used to determine whether a blockage is present.

摘要:
An apparatus and method for simulating human ophthalmic artery for testing of ultrasound devices is disclosed, whereby two chambers are provided and are capable of being independently pressurized, one representing the intra-cranial space and the other representing extra-cranial space, and whereby a tube running through both chambers is provided, simulating the course of the ophthalmic artery and capable of being pressurized to stimulate arterial pressure. The apparatus is operated by pressuring both chambers, and pumping a blood-imitating fluid through the vessel in a pulsatile manner.

A tappet clearance setting apparatus includes a screwdriver, a pneumatic portion, and a controller. The screwdriver engages the tappet screw and the pneumatic portion provides a monitored and air flow through an engine cylinder. The controller directs the screwdriver to tighten the tappet until the air flow through the cylinder is indicative of a valve opening. The controller then directs the screwdriver to reverse directions until the sensed air flow indicates that the valve has closed, which further indicates that the tappet screw is in a reference position. From the reference position, the controller directs the screwdriver to loosen the tappet a predetermined amount to establish the desired tappet clearance.
