摘要： An ultrasonic transducer includes a transducer element having a backing element bonded thereto. The thickness of the backing element is selected to be less than or equal to half the length of an ultrasonic pulse, expressed in wavelengths of the center frequency of the pulse, so that the first reflection from the back side of the backing element is received by the transducer element before the primary pulse rings down. A method for mounting the transducer that reduces the formation of air bubbles includes the steps of forming a peaked mound and continually lowering the transducer to flatten the mound against the underside of the transducer.

摘要： A low profile electrical plug includes a support plate formed from a rigid, nonconductive material such as a printed circuit board. Prongs extend perpendicularly from a face of the support plate and are oriented for insertion into a conventional electrical outlet. The prongs are adapted to snap into reciprocal apertures in the support plate during assembly. Paths of electrically conductive material are disposed on a face of the support plate and extend between the prongs and terminals formed in the edge of the support plate. A power cord has electrical conductors electrically connected to different ones of the prongs to provide an electrical connection to a remote device. For this purpose, each power cord conductor includes a connector adapted slide over one of the terminals and electrically contact a respective conductive path. The integral assembly of the power cord, support plate and prongs is molded in a nonconductive housing. The prongs exit perpendicularly from a flat face on the housing and the cord exits the housing generally parallel to the flat face. A handle is connected to the housing to facilitate removal of the plug from an outlet. In one embodiment, the handle pivots away from the housing to facilitate grasping. In another embodiment, the stretchable handle is fixedly secured to the housing.
