Abstract: A device for training the binocular function of the human visual system for optimal performance. The device is comprised of a horizontal shaft, with a handle substantially in the center of it. It has two stationary vertical posts. One post is affixed to each end of the shaft. The posts are aligned in a spaced apart relationship in the same vertical plane. When combined the elements of this device induce physiological diplopia and enable it to be used dynamically as visual biofeedback during training. The visual biofeedback is informative because it provides the user with proof that their visual system is focused binocularly. Training systematically and methodically recalibrates the musculature of the human visual system, thereby enhancing its performance. Use of the personal Binocular Trainer also increases the user's attention span and comprehension.

Abstract: There is described a semi-automatic fishing apparatus for retaining a baited fishing rod in an inclined, flexed configuration wherein it may be automatically released to an unflexed position in response to tensioning of the fishing line, as for example, by acceptance of the bait by a fish, so as to set the hook in the fish. The apparatus features an elongated inclined base member to which the fishing rod handle is secured at an acute angle to one end and to which the tip of the fishing rod is retained at the opposite other end below the plane of the base member in the flexed configuration through the agency of a latching device. The latching device is tripped directly by the downward movement of the line which line simply overlies the tripping mechanism without the need for complicated threading of the line through the tripping mechanism as in prior art devices.

Abstract: The disclosure relates to a novel device for performing signal convolution functions such as auto and cross correlation through the use of combined acoustic surface wave and semiconductor devices. A detector or pickup unit comprising a plurality of interdigital fingers coupled to associate semiconductor diodes is disposed on the surface of an acoustic substrate in the path of surface waves propagated along the surface of the substrate. The diodes are operatively connected to a summing bus from which an output signal indicative of some characteristics of the surface waves may be obtained.

Abstract: The disclosure relates to an acoustic surface wave device and method for long signal delays and bulk wave discrimination through the folding of a surface wave propagation path. A surface wave device is formed on the surface of an acoustic substrate and a surface wave, acoustic discontinuity is formed in the propagation path of surface waves propagated along the surface of the substrate. The acoustic discontinuity defines a reflecting surface for acoustic surface waves thereby deflecting incident surface waves along a reflecting path differing from the propagation path. Substantially all of the bulk waves propagated along the propagation path continue along this path and can be absorbed or otherwise dissipated. As a result, a substantially pure surface wave mode signal can be detected along the reflecting path. The surface waves may be reflected in this manner, i.e., by folding the path of the surface waves, a number of times as required to obtain a desired delay.

Abstract: A thin film piezoelectric transducer generates bulk mode ultrasonic elastic waves which propagate into a transmission medium, such as silicon. The wave is reflected back towards the first transducer by a reflecting surface. A second transducer is located adjacent to the first transducer and receives the acoustic wave from the reflected surface. The path length of the ultrasonic wave from the first transducer to the second transducer is long enough to enable the bulk wave to be in the Fraunhofer field. An acoustic absorbing material, such as indium, may be placed on the reflecting surface and on the surface containing the two transducers in selective areas to reduce undesired reflections. The structure is suitable for use in the microwave region wherein the insertion loss may be relatively constant over a given frequency band.
