In Re Alappat
''In re Alappat'', 33 F.3d 1526 (Fed. Cir. 1994), along with ''In re Lowry'' and the ''State Street Bank'' case, form an important mid-to-late-1990s trilogy of Federal Circuit opinions because in these cases, that court changed course by abandoning the ''Freeman-Walter-Abele Test'' that it had previously used to determine patent eligibility of software patents and patent applications. The result was to open a floodgate of software and business-method patent applications, many or most of which later became invalid patents as a result of Supreme Court opinions in the early part of the following century in '' Bilski v. Kappos'' and ''Alice v. CLS Bank''. Background Kuriappan Alappat was an employee of Tektronix, an oscilloscope manufacturer. He and two other employees (Edward Averill and James Larsen, but for convenience the three will be referred to collectively as Alappat) devised a form of "rasterizer," which is a device used in a digital oscilloscope to smooth waveform data be ...

United States Court Of Appeals For The Federal Circuit
The United States Court of Appeals for the Federal Circuit (in case citations, Fed. Cir. or C.A.F.C.) is a United States court of appeals that has special appellate jurisdiction over certain types of specialized cases in the Federal judiciary of the United States, U.S. federal court system. It has exclusive appellate jurisdiction over all U.S. federal cases involving patents, trademarks, government procurement, government contracts, veterans' benefits, public safety officers' benefits, federal employees' benefits, and various other categories. Unlike other federal courts, the Federal Circuit has no jurisdiction over cases involving Federal crime in the United States, criminal, Bankruptcy in the United States, bankruptcy, Immigration to the United States, immigration, or State law (United States), U.S. state law. Headquartered in Washington, D.C., the Federal Circuit was created in 1982 with passage of the Federal Courts Improvement Act, which merged the United States Court of Cus ...

Tektronix
Tektronix, Inc., historically widely known as Tek, is an American company best known for manufacturing test and measurement devices such as oscilloscopes, logic analyzers, and video and mobile test protocol equipment. Originally an independent company, it is now a subsidiary of Fortive, a spinoff from Danaher Corporation. Several charities are, or were, associated with Tektronix, including the Tektronix Foundation and the M.J. Murdock Charitable Trust in Vancouver, Washington. History 1946–1954 The company traces its roots to the electronics revolution that immediately followed World War II. It was founded in December 1945 as Tekrad. The name was similar to that of a California company, Techrad, so in 1946, the four partners, Howard Vollum, Jack Murdock and Miles Tippery, who had both served in the Coast Guard, and accountant Glenn McDowell, formed Tektronix, Inc. Each contributed an initial $2,600 for equal shares. Howard Vollum had graduated in 1936 from Reed Coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
En Banc
In law, an en banc session (; French for "in bench"; also known as ''in banc'', ''in banco'' or ''in bank'') is a session in which a case is heard before all the judges of a court (before the entire bench) rather than by one judge or a smaller panel of judges. ''En banc'' review is used for unusually complex or important cases or when the court feels there is a particularly significant issue at stake. United States Federal appeals courts in the United States sometimes grant rehearing to reconsider the decision of a panel of the court (consisting of only three judges) in which the case concerns a matter of exceptional public importance or the panel's decision appears to conflict with a prior decision of the court. In rarer instances, an appellate court will order hearing ''en banc'' as an initial matter instead of the panel hearing it first. Cases in United States courts of appeals are heard by three-judge panels, randomly chosen from the sitting appeals court judges of tha ...

O'Reilly V
O'Reilly ( ga, Ó Raghallaigh) is a group of families, ultimately all of Irish Gaelic origin, who were historically the kings of East Bréifne in what is today County Cavan. The clan were part of the Connachta's Uí Briúin Bréifne kindred and were closely related to the Ó Ruairc (O'Rourkes) of West Bréifne. O'Reilly is ranked tenth in the top twenty list of most common Irish surnames. It is also the patronymic form of the Irish name Reilly (Irish Gaelic: ''Uí Raghaile''). The name is commonly found throughout Ireland, with the greatest concentration of the surname found in County Cavan followed by Longford, Meath, Westmeath, Fermanagh and Monaghan, and the Province of Leinster. Naming conventions Overview It is usually anglicised as Reilly, Riley, and O'Reilly. The original form of the name, Ó Raghallaigh, denotes "from/of Raghallach", the name Raghallach thought to be derived from the compounds ''ragh'' (meaning "race") and ''ceallach'' (meaning "sociable").

Diamond V
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, orange, or red. Diamond also has a very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrostatic Deflection
Electrostatic deflection refers to a way for modifying the path of a beam of charged particles by the use of an electric field applied transverse to the path of the particles. The technique is called electro''static'' because the strength and direction of the applied field changes slowly relative to the time it takes for the particles to transit the field, and thus can be considered not to change (be static) for any single particle. Explanation The Lorentz force acts on any charged particle in an electrostatic deflection. Electrostatic deflection uses a special, simplified case of this general effect by limiting the field to an electric field. An electric field applies a force on a particle that is proportional to the strength of the field and to the charge on the particle. The direction of the applied force is the same as the direction of the electric field. For electrostatic deflection, the applied electric field is arranged so that it lies in the plane perpendicular to the ini ...

Cathode Ray Tube
A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen. The images may represent electrical waveforms ( oscilloscope), pictures (television set, computer monitor), radar targets, or other phenomena. A CRT on a television set is commonly called a picture tube. CRTs have also been used as memory devices, in which case the screen is not intended to be visible to an observer. The term ''cathode ray'' was used to describe electron beams when they were first discovered, before it was understood that what was emitted from the cathode was a beam of electrons. In CRT television sets and computer monitors, the entire front area of the tube is scanned repeatedly and systematically in a fixed pattern called a raster. In color devices, an image is produced by controlling the intensity of each of three electron beams, one for each additive primary color (red, green, and bl ...

Aliasing
In signal processing and related disciplines, aliasing is an effect that causes different signals to become indistinguishable (or ''aliases'' of one another) when sampled. It also often refers to the distortion or artifact that results when a signal reconstructed from samples is different from the original continuous signal. Aliasing can occur in signals sampled in time, for instance digital audio, or the stroboscopic effect, and is referred to as temporal aliasing. It can also occur in spatially sampled signals (e.g. moiré patterns in digital images); this type of aliasing is called spatial aliasing. Aliasing is generally avoided by applying low-pass filters or anti-aliasing filters (AAF) to the input signal before sampling and when converting a signal from a higher to a lower sampling rate. Suitable reconstruction filtering should then be used when restoring the sampled signal to the continuous domain or converting a signal from a lower to a higher sampling rate. For spa ...

Jaggies
"Jaggies" is the informal name for artifacts in raster images, most frequently from aliasing, which in turn is often caused by non-linear mixing effects producing high-frequency components, or missing or poor anti-aliasing filtering prior to sampling. Jaggies are stair-like lines that appear where there should be "smooth" straight lines or curves. For example, when a nominally straight, un-aliased line steps across one pixel either horizontally or vertically, a "dogleg" occurs halfway through the line, where it crosses the threshold from one pixel to the other. Jaggies should not be confused with most compression artifacts, which are a different phenomenon. Causes Jaggies occur due to the "staircase effect". This is because a line represented in raster mode is approximated by a sequence of pixels. Jaggies can occur for a variety of reasons, the most common being that the output device (display monitor or printer) does not have enough resolution to portray a smooth line. In addi ...
