A sonar system is provided including a sonar assembly configured to attach to a motor assembly of a watercraft or a watercraft. The sonar assembly includes sonar transducer element(s) that transmit sonar beam(s). The sonar system includes a display, processor(s), and a steering assembly configured to cause rotation of the sonar assembly or the motor assembly. The sonar system includes a memory including computer program code that causes the processor(s) to cause the sonar transducer element(s) to emit sonar beam(s), receive sonar return data from a coverage volume of the sonar transducer element(s), generate a sonar image of the coverage volume based on the sonar return data, receive an input from a user, determine a target in the underwater environment based on the input, and cause the steering assembly to adjust the coverage volume to maintain the target within the coverage volume as the watercraft moves relative to the target.

A depth sensing system is configured to track one or both eyes of a user. The depth sensing system includes a transducer chip comprising a phased array of ultrasound transducers that transmit a signal at an eye of the user and detect a reflected signal from the eye. A controller estimates an orientation of the eye based on the reflected signals received by the phased array. The depth sensing system may be part of a headset that includes a display element configured to display content to a user wearing the headset.

The invention relates to the use of sonar acoustic pulses to provide information about the status and composition of aquaculture farming tanks or ponds. In particular, the invention is directed to processes and systems comprising: a acoustic pulse transducer configured to transmit a acoustic pulse into an aquaculture farming tank or pond, a network of underwater sonar signal receivers; a computer connected to the network of underwater sonar signal receivers, said computer having a processor and memory, said memory having computer programming instructions saved thereon and executable on the processor, said computer programming instructions configured for receiving and comparing a signal difference between the acoustic pulse and the scattered return signal and for using the signal difference to output a signal difference data point related to a calculated shrimp biomass and distribution in the aquaculture farming tank or pond; a computer display connected to the computer and configured to display the signal difference data point related the calculated shrimp biomass and distribution.

Electronic tracking systems are disclosed for assisting users with locating objects in a sporting environment. One such system includes a ball tracking component that tracks a game ball while moving in the sporting environment, and a heads up display that is worn by the user. This heads up display has an electronic display screen with a transparent display area that dynamically displays images within the user's field of view. A processor, which communicates with the ball tracking component and heads up display, is programmed to detect movement of the game ball, and responsively determine launch characteristics and/or flight characteristics of the moving game ball. The heads up display displays the launch/flight characteristics contemporaneous with an object indication adjacent to or superimposed over the moving game ball as the game ball is visible through the transparent display area of the display screen within the user's field of view.
