Methods for creating apertures in a layer on a back side of a substrate that includes a microlens array on a front side thereof include curving the substrate into a cylindrical surface segment that defines an axis, so that the microlens array on the front side of the substrate faces the axis. A pulsed laser beam is scanned from the axis circumferentially along the cylindrical surface segment, to pass through the microlens array on the front side of the substrate and into the layer on the back side of the substrate to create the apertures, while simultaneously translating the substrate and/or the scanned pulsed laser beam axially relative to one another. Related apparatus and microlens array products are also disclosed.

The invention provides an apparatus and method for removing diatomaceous earth and contaminants from a filter and for filtering liquid using diatomaceous earth. Embodiments of the method can include a washdown process, a backwash process, and a filtering process. Some embodiments of the apparatus can include one or more filter cartridges with cartridge tubes to increase flow during the backwash process. Some embodiments of the apparatus can include a backwash sprayer to disturb contaminants during the backwash process. Some embodiments of the apparatus can include a removable lid to access the filter cartridges during the washdown process.

An optical data communication and power converter device includes a receiver circuit comprising an optical receiver. The optical receiver includes a photovoltaic device and a photoconductive device arranged within an area that is configured for illumination by a modulated optical signal emitted from a monochromatic light source of a transmitter circuit. The photovoltaic device is configured to generate electric current responsive to the illumination of the area by the modulated optical signal. The photoconductive device is configured to generate a data signal, distinct from the electric current, responsive to the illumination of the area by the modulated optical signal. A reverse bias voltage may be applied to the photoconductive device by the photovoltaic device, independent of an external voltage source. Related devices and methods of operation are also discussed.
