Abstract: A single pass inkjet printer that utilizes a modular printing system with one or more self-contained printing modules, where each printing module is easy to remove and replace from a large printing machine, thus resulting in an overall system that is easy to service and maintain. Each module is a self-contained printer including an ink supply, printhead drive electronics, and printhead assembly in order to provide one color or fluid of inkjet printing capability. Each module includes a precise three-point compliant self-aligning mount system to obtain accurate printhead positioning, and a unique integrated printhead tending system that includes a compact movable vacuum knife for cleaning the printheads, and a printhead capping station for sealing and protecting the printheads from the ambient environment when not in use.

Abstract: An alignment member for aligning electrical components. The alignment member includes a base, a telescoping portion and a spring. The base has a first spring receiving cavity which extends from a first end of the base to a spring engaging shoulder. The telescoping portion has a second spring receiving cavity with a spring cooperating surface. The spring is positioned in the first spring receiving cavity of the base and in the second spring receiving cavity of the telescoping portion. The spring has a length which is approximately equal to or slightly larger than the length of a cavity formed by the spring receiving cavity and the base receiving cavity when the alignment member is in an extended position. The spring is retained in a biased position to keep the telescoping portion extended until a force is applied to the telescoping portion by the mating alignment member.

Abstract: A gonioscopic attachment can attach to a gonioscope and can include atraumatic retention elements that are configured to engage an eye to retain the gonioscope relative to the eye. The gonioscopic attachment can be configured to position the gonioscope so that at least a portion of the concave distal surface of the gonioscopic optical element is spaced apart from the eye, and/or so that the curvature of the distal surface is angularly offset from the curvature of the eye. The gonioscope can include a fixation point configured to be visible to the subject when the gonioscope is positioned on the eye. In some embodiments, the retention elements can be incorporated directly into the gonioscope. A coupling mechanism can couple the gonioscope to a lid speculum. The gonioscope can include a light pipe, which can be configured to directly light into the eye.

Abstract: A system and method for generating a force from a voltage difference applied across at least one electrically conductive surface. The applied voltage difference creates an electric field resulting in an electrostatic pressure force acting on at least one surface of an object. Asymmetries in the resulting electrostatic pressure force vectors result in a net resulting electrostatic pressure force acting on the object. The magnitude of the net resulting electrostatic pressure force is a function of the geometry of the electrically conductive surfaces, the applied voltage, and the dielectric constant of any material present in the gap between electrodes. The invention may be produced on a nanoscale using nanostructures such as carbon nanotubes. The invention may be utilized to provide a motivating force to an object. A non-limiting use case example is the use of electrostatic pressure force apparatus as a thruster to propel a spacecraft through a vacuum.
