Abstract: A scale calibration device and method of use. The device may include a base supportable on and movable along a surface to a location. The base further includes a base surface for supporting a scale to be calibrated proximate the location. The device includes a frame assembly connected to the base and operable to support, in a position over the base surface, means for simulating a dead weight, the means being operable to apply a force to the scale supported on the base surface.

Abstract: Systems and methods for scale calibration. One example embodiment provides a system for calibrating a scale. The system may generally include an actuator for applying force to a platform of the medical scale, and an electronic processor communicatively coupled to the actuator. The electronic processor may be configured to control an actuator to apply, for a first interval, a first applied force having a first value greater than a target force value, and control the actuator to apply, for a second interval, a second applied force having a second value substantially equal to the target force value.

Abstract: A cogeneration machine with an oil and filter change feature is disclosed. The present invention makes it possible to change the oil and/or the oil filters of a reciprocating engine in cogeneration equipment without turning off the engine. A cogeneration system user can safely change the engine oil or oil filters in the system without effecting its operation or incurring the significant costs associated with taking the system off-line.
