Patent number: 10759201Abstract: In an example implementation, a method of adjusting frame length in an inkjet web press includes measuring a time T1 between a first sensor sensing a first mark and a second sensor sensing a second mark, and measuring a time T2 between the second sensor sensing the second mark and the first sensor sensing a next first mark. The method includes adjusting a gap between printed frames when T1 does not equal T2.Type: GrantFiled: October 29, 2018Date of Patent: September 1, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Carlos Millan-Lorman, Jason C.

Patent number: 10751003Abstract: Vital sign monitors are plagued by noisy photoplethysmography (PPG) data, making it difficult for the monitors to output consistently accurate readings. Noise in PPG signals is often caused by motion. The present disclosure provides improved techniques for reducing motion-related artifacts in optical/PPG measurements for vital signs monitoring. In general, techniques described herein are based on using measurements of reference sensors that include sensors other than optical sensors used for the optical measurements, e.g., biopotential sensors, bioimpedance sensors, and/or capacitive sensors. In particular, techniques described herein aim to filter PPG signals using substantially only the noise components of signals generated by reference sensors, by attenuating or altogether eliminating components of the signals generated by reference sensors which are indicative of the parameter the reference sensors are designed to measure.Type: GrantFiled: July 12, 2018Date of Patent: August 25, 2020Assignee: ANALOG DEVICES GLOBAL UNLIMITED COMPANYInventors: Roberto Munoz, Guillermo Serrano Leon, Carlos Millan Navarro

Patent number: 10144211Abstract: Examples disclosed herein relate to front-to-back registration of a printed content onto a print medium. In one example, a trigger signal generated by a sensor upon detection of a trigger mark on a first surface of a print medium is received. The trigger mark includes a leading edge and a trailing edge, wherein the leading edge and the trailing edge are non-parallel. Based on the trigger signal, a distance of the trailing edge from a point on the leading edge is determined. Once determined, a measure of lateral wander of the print medium with respect to the print path is obtained. The measure of the lateral wander is determined by comparing the distance between the leading edge and the trailing edge, with a threshold value.Type: GrantFiled: July 24, 2014Date of Patent: December 4, 2018Assignee: Hewlett-Packard Development Company, L.P.Inventors: Cesar Fernandez, Srinivas Bhakthavatsalam, Carlos Millan

Publication number: 20040046814Abstract: A system and method for providing thermal protection to printheads in a large format ink jet printer. In the system and method, an adaptive thermal print swath servo (“ATPSS”) module configured to divide a swath of a print operation into a plurality of individual cells is utilized. In a preferred embodiment, each cell is approximately four (4) inches long, although a user may configure the cell length for any length. The ATPSS module may be further configured to predict a peak temperature of each printhead in printing each cell of a swath. If any of the printheads is predicted to exceed a maximum allowed temperature (e.g., predetermined by the printhead manufacturer) in printing any of the cells, the ATPSS module may be further configured to divide an upcoming pass of the printhead across a recording medium into a series of sub-passes.Type: ApplicationFiled: September 4, 2003Publication date: March 11, 2004Inventors: Pere Josep Canti, Carlos Millan, Roger Vinas
