Abstract: A filtering method for evaluating patents comprises loading each unit of text or figure in a portfolio of patents into digital memory then comparing each unit of text or figure with all other units of text or figures in digital memory using digital data processing. The duplicate units of text or figures are determined and the earliest instance of each duplicate unit of text or figure is identified. The duplicate unit of text or figure, other than earliest instance, are marked as duplicate to create a filtered version of each patent in portfolio. The filtered version of each patent in portfolio is evaluated to determine the uniqueness of the patent specification and the interrelationships between the patents in the portfolio are determined. The interrelationships are illustrated in an electronic workspace for analyzing the portfolio of patents.

Abstract: A hand-held micro-fluid ejection device for manually ejecting fluid droplets onto a substrate during relative translational motion between the ejection device and a target area on the substrate. The ejection device includes a frequency generator to set a designated frequency signal for fluid droplet ejection by the device. The frequency generator is configured to operate open-loop with respect to the relative translational motion between the ejection device and the target area. An electronic processor uses the designated frequency signal to drive a micro-fluid ejection head that produces a predetermine droplet pattern. In some embodiments a manual tuner is provided to adjust the designated frequency. In some embodiments the designated frequency signal includes more than one component to control different elements of fluid being ejected.
