| 20110310182 | PRINTHEAD AND METHOD OF FABRICATING THE SAME - Disclosed is a printhead having at least one ink drop generator region, which includes an ink chamber, an orifice through which ink drops are ejected, and a heating element positioned below the ink chamber. The heating element includes a resistor defined therein and a nano-structured surface that is exposed to the ink fluid supplied to the ink chamber. The nano-structured surface takes the form of an array of nano-pillars. The printhead is fabricated by a method that includes: forming a heating element having an oxidizable metal layer as the uppermost layer; forming an aluminum-containing layer on the oxidizable metal layer; anodizing the aluminum-containing layer to form porous alumina; anodizing the oxidizable metal layer so as to partially fill the pores in the porous alumina with metal oxide material; and removing the porous alumina by selective etching to produce a nano-structured surface. | 12-22-2011 |

| 20090295613 | PERFORMING ANALOG-TO-DIGITAL CONVERSION BY COMPUTING DELAY TIME BETWEEN TRAVELING WAVES IN TRANSMISSION LINES - A method and device for converting an analog input electrical signal to a digital signal. A plurality of integrated active and/or passive transmission lines may be implemented with signal-dependant propagation velocities. The delay differences of pulses traveling through these transmission lines are compared, and the collective results are used to evaluate and subsequently quantize the input signal. | 12-03-2009 |
| 20100122904 | INCORPORATING CMOS INTEGRATED CIRCUITS IN THE DESIGN OF AFFINITY-BASED BIOSENSOR SYSTEMS - A biosensor system incorporating CMOS integrated circuits. In one type of biosensor system, the biosensor system includes a complementary metal-oxide-semiconductor (“CMOS”) integrated circuit. The biosensor system further includes an optical filter fabricated on the CMOS integrated circuit. Additionally, a plurality of capturing probes is optically coupled to the CMOS integrated circuit. Alternatively, another type of biosensor system includes a silicon substrate. The alternative biosensor system further includes active devices fabricated on the silicon substrate. Additionally, the alternative biosensor system includes a plurality of metal layers stacked on top of the active devices. Furthermore, the alternative biosensor system includes a passivation layer covering a top metal layer, where the passivation layer includes an opening configured to expose the top metal layer, where the opening is used as a sensing electrode. Additionally, the alternative biosensor system includes a plurality of probes attached to the sensing electrode. | 05-20-2010 |

| 20100228266 | Master Controller Having Redundant Degrees of Freedom and Added Forces to Create Internal Motion - An input device includes a handle coupled to a base by a linkage. The handle is manually movable relative to the base to provide a position input. The linkage has a plurality of links including a redundant link that permits internal motion of the linkage such that the linkage can move without moving the handle relative to the base. When a distance between the handle and a handle stop position is less than a threshold distance, a handle stop applies a first load to the handle. A drive system applies a second load to the redundant link responsive to the first load to create internal motion of the linkage that increases a distance between the handle and a handle stop position. The second load may be proportional to a cosine of an angle between a handle axis of motion and a redundant link axis of motion. | 09-09-2010 |
