The scraper comprises a metal edge. The actuator is coupleable to the scraper. When the actuator is coupled to the scraper and extended and retracted, the metal edge of the scraper is oriented to pass in proximity to a surface of the plurality of tines, thereby removing debris stuck in the tines.

Abstract: A power converter can be controlled to generate a target output power. The control process may include obtaining a target current reference for the power converter, sensing an output current of the power converter, and determining a difference between the target current reference and the sensed output current. The next switching duty cycle for the next switching period of the switching circuits in the power converter can be derived based on at least the present switching duty cycle of the present switching period, and the difference between the target current reference and the sensed output current. The switching circuits of the power converter can then be switched according to the derived next switching duty cycle in the next switching period.

Abstract: A power converter can be controlled to generate a target output power based on a reactive power reference and an active power reference. The control process may include monitoring a time-varying power signal (e.g., a power grid voltage signal from a power grid), and filtering the time-varying power signal to derive a filtered sine component of the time-varying power signal and a filtered cosine component of the time-varying power signal. A sine coefficient and cosine coefficient each based on at least the reactive power reference and the active power reference can be determined, and applied to the filtered sine component and filtered cosine component of the time-varying power signal, respectively. A target current reference of the power converter can then be set to include a sum of the current reference sine component and the current reference cosine component.

Abstract: A storage system is provided. The storage system includes a shelf, a number of elongated frame members and a number of support assemblies having a spherical coupling. The support assemblies are coupled to beams. The frame members extend downwardly from the support assemblies and are coupled to the shelf. The support assemblies' spherical coupling allows for the frame members to be disposed at an adjustable angle relative to the shelf. Thus, regardless of the spacing of the beams, the support assemblies are directly coupled to the beams.
