PF Flyers
PF Flyers is an American brand of Shoe, lifestyle shoes owned by Kassia Designs, LLC. Founded in 1937 by Goodrich Corporation, B.F. Goodrich, it is one of the original American sneaker brands. History In 1933, inventor Hyman L. Witman and rubber manufacturing company Goodrich Corporation, B.F. Goodrich patented the "Posture Foundation" arch support insole, and began adding the new technology to its shoes. B.F. Goodrich shoes with Posture Foundation became known simply as "PF" in 1937. In 1935, Canadian badminton player Jack Purcell designed a low, white-bleached badminton shoe made of canvas and rubber for B.F. Goodrich. Named after Purcell, it featured a blue "smile" across the toe of the shoe and provided more protection for the court. By 1944, PF Flyers released their first kids' collection, and created the slogan, "Run Faster, Jump Higher". Fashion trends in the 1940s and 1950s saw PF Flyers expand from gyms and ball fields to become fashionable active footwear; its main com ...

Power Factor
In electrical engineering, the power factor of an AC power system is defined as the ratio of the '' real power'' absorbed by the load to the ''apparent power'' flowing in the circuit. Real power is the average of the instantaneous product of voltage and current and represents the capacity of the electricity for performing work. Apparent power is the product of RMS current and voltage. Due to energy stored in the load and returned to the source, or due to a non-linear load that distorts the wave shape of the current drawn from the source, the apparent power may be greater than the real power, so more current flows in the circuit than would be required to transfer real power alone. A power factor magnitude of less than one indicates the voltage and current are not in phase, reducing the average product of the two. A negative power factor occurs when the device (which is normally the load) generates real power, which then flows back towards the source. In an electric power system ...

PF (firewall)
PF (Packet Filter, also written pf) is a BSD licensed stateful packet filter, a central piece of software for firewalling. It is comparable to netfilter (iptables), ipfw, and ipfilter. PF was developed for OpenBSD, but has been ported to many other operating systems. History PF was originally designed as replacement for Darren Reed's IPFilter, from which it derives much of its rule syntax. IPFilter was removed from OpenBSD's CVS tree on 30 May 2001 due to OpenBSD developers' concerns with its license. The initial version of PF was written by Daniel Hartmeier. It appeared in OpenBSD 3.0, which was released on 1 December 2001. It was later extensively redesigned by Henning Brauer and Ryan McBride with most of the code written by Henning Brauer. Henning Brauer is currently the main developer of PF. Features The filtering syntax is similar to IPFilter, with some modifications to make it clearer. Network address translation (NAT) and quality of service (QoS) have been i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patients' Front
The Socialist Patients' Collective (German: ''Sozialistisches Patientenkollektiv'', and known as the SPK) is a patients' collective founded in Heidelberg, West Germany, in February 1970, by Wolfgang Huber (born 1935). The kernel of the SPK's ideological program is summated in the slogan, "Turn illness into a weapon", which is representative of an ethos that is continually and actively practiced under the new title, Patients' Front/Socialist Patients' Collective, PF/SPK(H). The first collective, SPK, declared its self-dissolution in July 1971 as a strategic withdrawal but in 1973 Huber proclaimed the continuity of SPK as ''Patients' Front''. The SPK assumes that illness exists as an undeniable fact and believe that it is caused by the capitalist system. The SPK promotes illness as the protest against capitalism and considers illness as the foundation on which to create the human species. The SPK is opposed to doctors, considering them to be the ruling class of capitalism and resp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PF Keys
A function key is a key on a computer or terminal keyboard that can be programmed so as to cause an operating system command interpreter or application program to perform certain actions, a form of soft key. On some keyboards/computers, function keys may have default actions, accessible on power-on. Function keys on a terminal may either generate short fixed sequences of characters, often beginning with the escape character (ASCII 27), or the characters they generate may be configured by sending special character sequences to the terminal. On a standard computer keyboard, the function keys may generate a fixed, single byte code, outside the normal ASCII range, which is translated into some other configurable sequence by the keyboard device driver or interpreted directly by the application program. Function keys may have abbreviations or pictographic representations of default actions printed on/besides them, or they may have the more common "F-number" designations. History T ...

South Vietnamese Popular Force
The South Vietnamese Popular Force ( vi, nghĩa quân, PF) (originally the Self-Defense Corps) was a part-time local militia of the Army of the Republic of Vietnam (ARVN) during the Vietnam War. The South Vietnamese Popular Force mainly protected homes and villages in South Vietnam from attacks by the Viet Cong (VC) and later the People's Army of Vietnam (PAVN). The Popular Force resembled the Viet Cong and PAVN strategy, organization and structure, Local Force and village-guerrilla level component of the VC, while the South Vietnamese Regional Force, Regional Force was a full-time force available for operations within a province. The Popular Force was initially very poorly-trained and equipped, but often bore the brunt of PAVN/VC attacks. PF and Regional Force units were responsible for inflicting an estimated 30% of the total PAVN/VC casualties throughout the war, and were much more capable of fulfilling ambush and small-unit movement, reconnaissance and detection roles than larg ...

Pforzheim
Pforzheim () is a city of over 125,000 inhabitants in the federal state of Baden-Württemberg, in the southwest of Germany. It is known for its jewelry and watch-making industry, and as such has gained the nickname "Goldstadt" ("Golden City"). With an area of , it is situated between the cities of Stuttgart and Karlsruhe at the confluence of three rivers (Enz, Nagold and Würm). It marks the frontier between Baden and Württemberg, being located on Baden territory. From 1535-65, it was the home to the Margraves of Baden-Pforzheim. The City of Pforzheim does not belong to any administrative district (''Kreis''), although it hosts the administrative offices of the Enz district that surrounds the town. During World War II, Pforzheim was bombed by the Allies a number of times. The largest raid, and one of the most devastating area bombardments of World War II, was carried out by the Royal Air Force (RAF) on the evening of 23 February 1945. Nearly one third of the town's populati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Project Fanboy
Project Fanboy (PF) is an American website that publishes news, interviews and reviews about the American comic book industry. In addition, the site is host to comic book fan-voted awards. It was founded by Stephen Jondrew and Scott Williams in the fall of 2005 as an alternative site that covers mainstream comic book news, but also promotes smaller independent works. History The Project Fanboy website was launched in 2005 as an independently run promoter of comic books and creators in the comic book industry. A little known site in its first three years, it eventually began publishing interviews and reviews of independent comic books in 2008. The site garnered little interest until May 2008, with the introduction of the annual Project Fanboy Awards. At the 2009 MegaCon comic book convention the winners of the 2008 Project Fanboy Awards were announced. The awards sparked controversy amongst comic book fans with the announcement of Jim Balent's company Broadsword Comics receivi ...
