Disclosed by way of example embodiments is a wireless communication system transmitting or receiving a wireless signal according to an orientation of the wireless communication system. In one aspect, the wireless communication system includes an antenna operable in different configurations. In each configuration, the antenna has a corresponding antenna gain in a direction with respect to the antenna. The wireless communication system further includes a sensor for determining an orientation of the wireless communication system. According to the determined orientation, the antenna is configured to transmit or receive the wireless signal in a corresponding configuration. Hence, the wireless communication system disposed in different orientations can successfully communicate with another wireless communication system.

Techniques for measuring a monument, including obtaining a set of two or more images of a monument environment, detecting a set of markers in the set of images, wherein the set of markers are positioned on a plane level with respect to gravity by a leveling device, and wherein the leveling device is configured to automatically level the markers, generating a virtual representation of the monument environment with respect to gravity, mapping the monument to a virtual representation, determining one or more slopes and dimensions of the monument based on the mapped monument and the gravity plane, and outputting the one or more slopes and dimensions of the monument.

A smart pool skimmer is disclosed. In one embodiment, the pool skimmer includes a body housing having electronics and sensors extending from the body housing to monitor pool conditions. The sensors detect a plurality of pool condition, including but not limited to pH, ORP, temperature, water level, water movement, chlorine levels, and salt concentration. The smart pool skimmer receives data from the sensors and sends the information to a user computing device or a cloud-based analytics server, which tracks conditions of the pool water. A solar panel may be provided on the housing to enable the smart skimmer to run on renewable energy. Additionally, visual light indicators can be mounted on top of the cover plate to provide visual indications of pool conditions.

An automatic guided vehicles (AGV) can include: motors, wheels, motor controllers, and batteries coupled to an elongated frame. The two wheels can be mounted on opposite sides of the elongated frame. The wheels can be coupled to motors which can be controlled by motor controllers. The motors and motor controllers can be attached to the frame. The center of gravity can be lower than the axis of rotation of the wheels so that the AGV will passively rotated into an upright position. A connector flange can be mounted on top of a payload holder column mounted to a center portion of the AGV frame. Objects can be mounted on or towed by the connector flange.
