Abstract: A method is provided for using a single-pixel imager in order to spatially reconstruct an image of a scene. The method can comprise the following: configuring a light filtering device including an array of imaging elements to a spatially varying optical filtering process of incoming light according to a series of spatial patterns corresponding to sampling functions. The light filtering device can be a transmissive filter including a first membrane, a second membrane, and a variable gap therebetween. The method further comprises tuning a controller for manipulating a variable dimension of the gap; and, measuring, using a photodetector of the single-pixel imager, a magnitude of an intensity of the filtered light across pixel locations in the series of spatial patterns. The magnitude of the intensity can be equivalent to an integral value of the scene across the pixel locations.

Abstract: A printer includes a printhead configured to eject high viscosity material and refill a reservoir in the printhead with high viscosity material. The printhead includes a transducer having an electroactive element and a member to which the electroactive element is mounted. An electrical signal activates the electroactive element to move the electroactive element and the member in the reservoir of high viscosity material. This movement thins the high viscosity material and enables the printhead to eject the thinned material while refilling the reservoir. The apertures through which the thinned material is ejected share a common manifold without separate chambers for each of the apertures.

Abstract: A printer includes a printhead configured to eject high viscosity material and refill a manifold in the printhead with high viscosity material. The printhead includes a layer having an opening to form a reservoir to hold a volume of a high viscosity material and at least one member positioned within the receptacle formed by the opening in the layer. The at least one member has an electroactive element mounted to the member, and an electrical signal generator is electrically connected to the electroactive element. A controller operates the electrical signal generator to activate selectively the electroactive element with a first electrical signal to move the at least one member and thin the high viscosity material adjacent the at least one member to enable the thinned material to move away from the at least one member.
