A marine sonar display device comprises a display, a memory element, and a processing element. The processing element is configured to transmit a transmit electronic signal to a frequency steered sonar element that transmits an array of sonar beams into a body of water in a first direction towards the front of the marine vessel forming a first sonar wedge and a second array of sonar beams into a body of water in a second direction directly below the marine vessel forming a second sonar wedge, receive a receive electronic signal from the frequency steered sonar element, generate an array of sonar image slices, identify a gap in an underwater area between the first sonar wedge and the second sonar wedge, and control the display to visually present the array of sonar image slices in near real time and a sonar image slice in the gap.

Frequency steered sonar user interface

A transducer system comprises a first frequency steered transducer array element and a second frequency steered transducer array element that is spaced apart from the first frequency steered transducer array element. The system additionally includes a processing element in communication with the first and second frequency steered transducer array elements. The processing element is configured to receive a first receive electronic signal from the first frequency steered sonar array element, receive a second receive electronic signal from the second frequency steered array sonar element, compare a difference in amplitude between the first receive electronic signal and the second receive electronic signal to determine a cross-track position of an underwater target, and control a display to present an indication of the cross-track position of the underwater target.

Frequency steered sonar array system with three-dimensional functionality

A marine sonar display device comprises a display, a memory element, and a processing element. The display displays sonar images. The memory element stores sonar data. The processing element is configured to transmit a transmit electronic signal to a frequency steered sonar element which transmits an array of sonar beams into a body of water, each sonar beam transmitted in a different angular direction, receive a receive electronic signal from the frequency steered sonar element, the receive electronic signal including a plurality of frequency components, calculate an array of sonar data slices, one sonar data slice for each frequency component, generate an array of sonar image slices, one sonar image slice for each sonar data slice, and control the display to visually present the array of sonar image slices in near real time and a historical sequence of at least one sonar image slice.

A golf launch monitor is configured to determine a flight characteristic of a golf ball. The golf launch monitor includes two low-speed cameras, a trigger device, and a processor. The trigger device is configured to detect a golf swing. The processor is configured to instruct, upon the trigger device detecting said golf swing, the first camera to capture the first ball image; instruct the second camera to capture the second ball image after a time interval, wherein the time interval is less than the first frame rate and the second frame rate; and determine, based at least in part on the first ball image and the second ball image, the flight characteristic of the golf ball.

Hybrid golf launch monitor

A transducer assembly comprises a housing and a plurality of frequency steered transducer array elements. Each of the transducer array elements includes a plurality of piezoelectric elements. The frequency steered transducer array elements are configured to receive a transmit electronic signal including a plurality of frequency components and to transmit an array of sonar beams into a body of water. Each sonar beam is transmitted in an angular direction that varies according to one of the frequency components of the transmit electronic signal. The frequency steered transducer array elements are positioned within the housing in a fan-shaped configuration where an end section of at least two of the frequency steered transducer array elements are within an intersection range of each other.

Frequency steered sonar array orientation

A frequency steered sonar element comprises a transducer element and a grating element. The transducer element presents a longitudinal axis and is configured to receive a transmit electronic signal and generate an acoustic wave with a frequency component corresponding to a frequency component of the transmit electronic signal. The grating element presents a longitudinal axis and is oriented such that a longitudinal axis of the grating element and a longitudinal axis of the transducer element form an acute angle. The grating element includes a first surface and an opposing second surface. One or more of the surfaces includes one or more grooves distributed thereon, the one or more grooves including first and second facets. The grating element is configured to emit a sonar beam in an angular direction which varies according to the frequency component of the acoustic wave.
