Abstract: In ultrasonic echoscopy, when an object to be examined has overlying layers of a medium (for example, fat, muscle, skin or bone) which have different ultrasonic transmission characteristics from those of the object, the echogram of the object is usually distorted. To reduce that distortion, the present invention uses a transducer comprising an array of ultrasonic transducer elements operated in a higher resolution mode than its normal imaging mode, to obtain information about the geometry of the overlying layers. Using this information and a knowledge of the transmission characteristics of the overlying layers, amplitude and phase corrections are calculated, to enable the transducer, when operated in its normal imaging mode, to generate a required beam of ultrasound. The corrections are then applied and an echogram of the object, with reduced distortion, is obtained while operating the transducer in its normal imaging mode.

Abstract: Echoscopes incorporating signal processing circuits capable of providing a more complete and useful display of information received as a train of electrical signals. In one circuit, which is essentially a compression amplifier, the amplitude range of the input signal is limited by way of two or three amplitude limiting stages and an adder connected to sum the output of the first and last stages provides an advantageous output to input characteristic for the circuit.The second circuit includes filter means and derivating means to separately process the input signal, and an adder to combine the outputs of these means to obtain a signal of enhanced utility.

Abstract: The present invention provides a small, cylindrical hinge, or pivoting pin, which can be configured to produce various profiles of torque versus angle. The desired profile of torque versus angle is achieved by the shapes of the hinge shaft and the spring plates of the hinge. Detents at one or more angular positions can be achieved, with or without frictional damping torque at other angles. The friction of our hinge is produced symmetrically about the hinge axis, eliminating the problems associated with asymmetric construction.

Abstract: A hinge that provides equilibration and variable friction for a display screen or a laptop lid. In the preferred embodiment, a torsion rod provides a restoring force which increases as the lid is moved either direction from its vertical position. A friction hinge, of well know design, uses a spring band about a shaft. One end of the torsion rod is coupled to the end of the band of the friction hinge, so that the moment in the torsion rod increases or decreases the moment in the spring band of the hinge, modifying the frictional torque accordingly. This allows the frictional torque to be low as the lid is first opened, and larger as the display reaches the useful range of its motion.
