Abstract: A disinfection device including a pipe with a taper, inlet, and outlet; an ultraviolet laser; a beam steering device and a transparent layer. The laser, located at a smaller diameter end of the pipe, projects a laser beam towards a larger diameter end of the pipe. The laser beam projects through and/or off the beam steering device and through the transparent layer at a plurality of angles in a cycle. The beam steering device reflects, refracts and/or deflects the laser beam at angles such that a laser beam profile projects through part or all of an inner profile of any point along the taper in the cycle. The pipe receives a fluid that passes through the pipe. One of the inlet or the outlet is located at the smaller diameter pipe end and the other of the inlet or the outlet is located at the larger diameter pipe end.

Abstract: A technique for operating a data storage system that includes a non-volatile memory array controlled by a controller includes storing, in the non-volatile memory array, first data whose frequency of access is above a first access level in a bandwidth optimized code word. Second data whose frequency of access is below a second access level is stored in the non-volatile memory in a code rate optimized code word.
