Abstract: A mobile cleaning system (10) that enables touch-free, daily cleaning and disinfecting to areas or locations within an establishment is provided. The system includes generally a push cart (12) having front (18) and rear (20) sections spaced between vertically upstanding side sections (22A-B). One or more sections of the cart (12) include a modulated space configurable with one or more cleaning and/or disinfecting modules for performing and supporting a cleaning and/or disinfecting operation. A tool drip tray (30) extends outward from at least one of the sections beneath a tool storage location (32A-B) for preventing liquid or debris from dropping onto a surface beneath the cart (12) while stationary or in transit.

Abstract: Systems and methods are provided for directionally filtering signals by projecting a received signal onto a subspace substantially orthogonal to selected interfering signals. The received signal typically comprises at least one signal of interest, at least one selected interfering signal, and noise. The received signal may further comprise other signals, including non-selected interfering signals. The projection of the received signal results in substantially no contribution from the selected interference signals on the signal of interest. For example, substantially no residual energy of the selected interference signals remains as an influence on the signal of interest. In one embodiment, a system generates a converted matrix having a substantially orthogonal set of vectors. Each vector may represent one or more selected interfering signals. The vectors may comprise code characteristics of the selected interfering signals. A directional filter uses the matrix to perform the projection.
