Abstract: Aspects discussed herein are directed to ergonomic pointing device systems. In one example, a pointing device system includes an elongate base member, a sleeve disposed to fit over at least a portion of the elongate base member, the sleeve configured to rotate about the elongate base member in a first direction and slide about the elongate base member in a second direction substantially orthogonal to the first direction, where the sleeve includes a pattern on a surface thereof, and a sensor disposed within the elongate base member and positioned to detect at least one of a rotational movement of the sleeve relative to the sensor and an axial movement of the sleeve relative to the sensor based at least in part on a variation of the pattern within a field of view of the sensor.

Abstract: Devices and systems for noninvasively and nondestructively sensing a signal in an electrical outdoor device, such a fishing transponder, are described. The device can include a first electrical connection to connect to a port on a main unit of an echo-location device, a second electrical connection to connect to a port on a transponder, the second electrical connection being in bi-directional electrical communication with the first connection to send a power signal from the main unit to the transponder and return an echoed signal to the main unit, and a third electrical connection to sense the signals between the first electrical connection and the second electrical connection. Positioning data is also created and stored with the signal data. The positioning data can be used to control acquisition of data. Systems and methods for processing the sensed data are described. Reports can be generated using the data and, in some reports with the positioning data.
