Abstract
A circuit means including a power source, a cathode ray tube, a source of high frequency sound, a transducer means for emitting and receiving sound signals, and mode control means for varying the visible output of energy across said cathode ray tube for making various anatomical measurements by emitting high frequency sound into an anatomy through said transducer, whereby the amplitude and frequency of reflected signals received by said transducer will be visibly reflected on said cathode ray tube.
Claims7
An anatomy testing and measuring device for determining pregnancy and measuring backfat, copmprising,
- a housing having an outer surface,
- a first circuit means within said housing for electrically generating ultrasonic pulses, transmitting said pulses into an animal body, receiving the echoes of said pulses from said animal body, selectively processing said pulses for visual display, and visually displaying said pulses to determine pregnancy in a sow, pregnancy in a cow and to measure the backfat of cattle,
- said first circuit means having electrically interconnected transmitter means, receiver means, and a cathode ray tube display means with a multiposition mode switch means,
- said cathode ray tube display means having a cathode ray tube on said outer surface, a horizontal sweep generator, a horizontal deflection amplifier, a vertical deflection amplifier, a gain control means, and said mode switch means electrically interconnected,
- said mode switch means having at least first, second and third positions, said first position selecting a first predetermined sweep rate of said sweep generator and a first predetermined level of the base line of the display on said cathode ray tube to determine pregnancy in a sow, said second position selecting a second predetermined sweep rate of said sweep generator and a second predetermined level of said base line of the display on said cathode ray tube to determine pregnancy in a cow and said third position selecting a third predetermined sweep rate of said sweep generator and a third predetermined level of said base line of the display on said cathode ray tube to determine backfat thickness,
- a transducer means remote from said housing and electrically connected to said first circuit means for transmitting ultrasonic pulses into said animal body and receiving the echoes of said pulses, and
- power means for powering said first circuit means.
