A tool with multiple measurement markings for use in assessing the depth and width of a hole or crevasse while gardening, landscaping, or performing other forms of excavation. The tool may also be used to measure distances on the ground or the height of various objects. The tool includes a handle with a tool attachment, such as a shovel or hoe blade, affixed to the proximal end of the handle. The tool has multiple lines of measurement markings across the front or back of the handle and attachment. These lines may start at the tip of the attachment and continue sequentially to the distal end of the handle. There may also be an additional line of measurement markings on the back of the handle with a starting point at the distal end of the handle. The attachment itself also may be marked with one or more lines of measurement markings on the front or back of the attachment.

An electronic battery tester for testing a storage battery includes a Kelvin connection configured to electrically couple to the storage battery and a microprocessor configured to determine a dynamic parameter of the storage battery. A forcing function source is configured to apply a forcing function signal to the storage battery through the Kelvin connection. A sensor is electrically coupled to the storage battery and configured to sense an electrical response of the storage battery to the applied forcing function signal. A tire tread gauge is arranged to be inserted into a tread of a tire. The tire tread gauge including a visual indicator. An image capture device is configured to capture an image of the tire tread gauge when the tire tread gauge is inserted into the tread of the tire.

An example device includes a housing including a top portion, and a lower portion which connect together to house a spring, and a bushing disposed inside the housing with a backside of a bushing rested against the spring, and the backside of the bushing is in contact with a probe tip of a depth measurement gauge disposed in a top portion of the housing.

Systems, methods, and apparatus for acquiring surface profile information (e.g., depths at multiple points) from limited-access structures and objects using an autonomous or remotely operated flying platform (such as an unmanned aerial vehicle). The systems proposed herein use a profilometer to measure the profile of an area on a surface where visual inspection has indicated that the surface has a potential anomaly. After the system has gathered data representing the surface profile in the area containing the potential anomaly, a determination may be made whether the collected image data indicates that the structure or object should be repaired or may be used as is.

An agricultural trench depth sensing system having a trench implement adapted to be disposed in a soil trench opened in a soil surface. In one embodiment an ultrasonic sensor detects a distance to an upper surface of said trench implement or a target disposed thereon. In another embodiment, said trench implement includes one or more fingers which rotate with respect to said trench implement to detect the soil surface relative to said trench implement. In another embodiment, said trench implement includes side sensors for detecting the sidewall of the soil trench.
