Abstract: A health monitoring system for caged birds is described. An enclosure containing sensors and associated circuitry mounts to the outside of a bird cage with a perch protruding into the cage. The sensors included in the present embodiment are a strain gauge load cell for bird weight measuring, a temperature sensor, and an ambient light sensor. The load cell is used with a perch such that the bird's weight can be measured whenever they alight upon the perch. Also included is a piezoelectric sensor to measure vibration data from the cage itself, which is used as a proxy for the bird's activity level. Associated circuitry and software processes and transmits this data to an internet-hosted server. The user can access this information to track a caged bird's weight, activity level, and environmental conditions over time.

Abstract: A surface treatment robot including a robot body, a differential drive system mounted on the robot body and configured to maneuver the robot over a cleaning surface, a liquid applicator carried by the robot body, and a collection assembly carried by the robot body and configured to remove waste from the cleaning surface. The robot body has a forward portion and a rear portion, with the forward portion preceding the rear portion as the robot moves in a forward direction over the cleaning surface. The liquid applicator is configured to dispense a liquid to the cleaning surface such that at least a portion of the liquid is dispensed rear of the collection assembly as the robot moves in the forward direction.
