Abstract: Apparatuses and methods determine positional information from a reflected optical signal for an object on a per pixel basis. A spread spectrum imaging system includes a transmitting module transmitting a transmitted optical signal that illuminates a target space and contains a transmitted pulse that is modulated with a first pseudo-noise (PN) code. The imaging system includes a receiving module that receives a reflected optical signal from an object. The reflected signal is processed by an optical array that detects a detected signal from the reflected optical signal, where the detected signal contains a plurality of pixels spanning a target space. When the determined PN code corresponds to the selected PN code, image information and the positional information is presented for the object. When different positional information is obtained for different pixels in the image, the imaging system may determine that different objects appear in the received image.

Abstract: A roller cleaning assembly for cleaning water-soluble paint from a paint roller cover has two major components, namely an enclosure and a spray jet component. The enclosure has a rigid sidewall, preferably of rectangular cross section, open at the bottom to permit free drainage and has a top wall with a central round opening of sufficient diameter to accommodate the roller cover. A u-shaped channel can grip the neck portion of the roller handle. The jet component is biased by a spring-like interference fit in the interior of the enclosure. A jet component has an inlet tube with a female fitting to attach to a source of water, and first and second riser pipes that rise from the inlet tube and which contain jet outlets that are spaced at intervals. The riser pipes direct jets of water and the roller cover to dislodge paint from the nap and to impart a spin to the roller. A bracket can be employed to mount the enclosure on a tank or bucket.
