Abstract: Acoustic energy is used to detect and identify objects buried in soil by imaging acoustic energy reflected from the soil and buried objects. Acoustic energy is injected into soil at an oblique angle relative to the surface of the soil, reflected and received. Signals representative of the reflected energy are processed to generate image signals used to generate images representative of the reflected energy. Objects buried within the soil are identified by viewing the images. In one embodiment, obliquely oriented acoustic energy signals are carried from a source to a soil sample by a first duct and reflections of that energy are carried to a receiver within an adjacent second duct. The ducts acoustically isolate the source from the receiver. A beveled end of the first duct and the second duct are supported above the soil sample for noncontact operations. In another embodiment, an acoustic energy source is obliquely supported upon and forced into engagement with soil in a reservoir. The reservoir is placed in contact with soil to be probed to effect a soil "impedance match" for oblique injection of acoustic energy into the soil. An acoustic energy receiver contacts the soil adjacent to the reservoir to receive acoustic energy reflected from the soil and objects buried within the soil. Pulse compression increases penetration depth. To compensate for soil attenuation characteristics, frequency-swept sinusoidal acoustic energy pulses are preferably amplitude modulated to have an exponentially changing envelope.

Abstract: A method and apparatus is described for modulating a color display in which the blended color is dependent upon the magnitude of N electrical signals which vary with the parameters of an audio signal. Known color pattern generators contain too many variables for a watching subject to be able to correlate them. This invention displays a single blended color which is related to the characteristics of the sound input.

Abstract: Tissue attenuation of ultrasound energy is determined by transmitting a wide band ultrasonic pulse into tissue and obtaining a measure of the average center frequency of the reflected pulse between two levels in the tissue. The log amplitude decay is estimated from a reflected pulse, and the attenuation coefficient is then obtained from the ratio of log amplitude decay to average center frequency between the two levels.

Abstract: This invention is a fluorescent light testing device. It is difficult to determine which fluorescent light or lights may be weak or on the verge of failing when a plurality of lights are disposed in the same general area. This is particularly true when the lights are of the overhead type and the higher the ceiling, the greater the problem. The present invention is a listening device on an extended boom type member to allow the user therof to readily determine which fluorescent lamp is humming thus indicating weakness or imminent failure so that the same can be replaced both to reduce energy use and to keep the lighting system at peak performance.

Abstract: A time gain control (TGC) signal for a variable gain amplifier in an ultrasonic scanner is derived by determining the attenuation at many levels in the object under examination and then constructing the TGC signal based on the cumulative attenuation of an ultrasonic signal through the object. A zero crossing detector such as a Schmitt triggered monostable multivibrator receives a reflected ultrasonic wave signal and generates pulses which are counted during time intervals corresponding to a depth level in the object. By comparing the zero crossing density at one level to the zero crossing density at another level a measure of attenuation between the two levels is obtained.
