Patent number: 8902426Abstract: A densitometer includes a plurality of light-emitting diodes (LEDs) and at least one sensor. The LEDs are activated one at a time in a sequential, repeatable order. Photonic energy from each LED is reflected off an entity and is incident upon the sensor(s). Circuitry samples or acquires signaling from the sensor(s) in accordance with the respective LED activations. Signaling from the densitometer can be used in controlling ink-jetting printers or other apparatus.Type: GrantFiled: January 31, 2013Date of Patent: December 2, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Javier Gonzalez Bruno, Marti Rius Rossell, Jordi Ferran Cases

Patent number: 8702191Abstract: A method and apparatus for controlling firing energy in a printer pen of a thermal inkjet printer are described. A digital voltage value representative of a voltage output by a printer-pen power supply is obtained. The printer-pen power supply is electrically coupled to a switch. The switch is electrically coupled to a nozzle resistor and is controlled using a switch logic signal. A voltage level of the switch logic signal is set based on said digital voltage value and a voltage drop due to a parasitic resistance between the printer-pen power supply and the switch.Type: GrantFiled: July 5, 2012Date of Patent: April 22, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Pere Esterri Pedra, David Soriano Fosas, Javier González Bruno, Eduard Pamies Corominas
