A data processing apparatus is provided, which includes processing circuitry. The processing circuitry is configured to acquire a data set from target detected by a detection apparatus, perform rendering of the data set, and generate a plurality of views arranged on a screen. Each view of the plurality of views includes a plurality of pixels. Each pixel included in the plurality of views is associated with a plurality of pieces of information including a first information displayed on the screen and a second information that indicates a view among the plurality of views to which the pixel belongs.

Disclosed is inter alia an apparatus (63) for sensing a movement of an object (10, 11) relative to a fluid (12, 13), e.g. for sensing relative movements of a surf board in water. A particular characteristic of the invention is that the housing (21) is mounted in fixed arrangement to a surface (20) of the object, the housing receiving a spring member (62) having a plurality of blades (25a, 25b, 25c, 25d), wherein each blade has an outer end (27) which is fixed to the housing, and an inner end (28) which is connecting to a center portion (65) of the spring, the plurality of blades defining a plane (73), wherein a plurality of strain gauges (26a, 26b, 26c, 26d) is positioned on the blades, and wherein a rigid pin (17) is mounted on the center portion of the spring member which is extending in a direction of a normal vector (74) of the plane and which is protruding from the surface (20) of the object and configured to dip into the fluid.

A camera produces image data representing an image of a surrounding view of a watercraft. A controller obtains the image data. The controller recognizes an image representing a specific mark in the image data. With reference to a control data set, the controller obtains watercraft operating information associated with the specific mark recognized in the image data. The control data set defines a relationship between the specific mark and the watercraft operating information.

A boat sharing system includes a non-transitory computer readable memory for receiving and storing data for routes previously traveled. The route data includes starting and ending points and points of interest along the routes. The memory receives and stores data related to boat types, equipment for boating activities and boat drivers. A processing system accesses the memory and is configured to: display the stored data; receive and store route data and trip timing, boat type, equipment, boat driver requirements and activity desires for a present user; compare the present user's desired route, timing, activity, equipment and boat driver requirements with previously stored data. The system provides at least one previously stored set of route, boat, activity, equipment and operator data as an option for the present user; provides proposed timing, starting and ending points for the suggested route; and permits the present user to confirm selection of the suggested route.
