Kempster Blanchard Miller. Kempster Blanchard Miller (August 14, 1870 – November 22, 1933) was an American engineer, author, and businessman. He is known for his many writings in the field of electrical engineering, electrical design, and the early telephone industry. His best known work was American Telephone Practice, considered for many years to be the seminal textbook on early telephone design and function.

Personal life
Miller was born in Boston, Massachusetts, to Joseph Kempster Miller and Eliza (Blanchard) Miller, he spent his childhood in Washington, D.C., before earning his engineering degree from Cornell University in 1893. In 1897 he married Antha Knowlton, and they had three daughters, Dorothea, Antha, and Ruth.

Notable Family Members
Daughter Ruth Miller, also known as Ruth Kempster and Ruth Blanchard Miller, was a distinguished artist whose work was exhibited (and won a silver medal) in the 1932 Olympics.

His brother was businessman, rancher and citrus farmer Azariel Blanchard Miller (1878–1941), founder of the city of Fontana, California.

Career
After graduating from Cornell, Miller worked for a time in the US Patent Office as an examiner. In 1897, he found employment at Westinghouse Electric and Manufacturing, but left after only months to work as an electrical engineer for the Western Telephone Construction Company in Chicago as chief electrician. Starting in 1898, he began a career as book author in telephony and telegraphy, and contributing and editing correspondence school text books. In 1899, he published his seminal work American Telephone Practice, and became electrical engineer at the Kellogg Switchboard & Supply Company, quickly ascending to lead the experimental shop and laboratory. At Kellogg he was an unwitting accomplice to the secret takeover by the Bell Telephone Company, reversed after a lawsuit by the company's founder, Milo G. Kellogg. He then formed an engineering consulting firm with Samuel G. McMeen in 1904 in Chicago, Illinois, a partnership he maintained until 1919, when he became manager of the North Electric Manufacturing Company. After 1922, he returned to consulting and wrote numerous papers and treatise in telephony technology.

American Telephone Practice
In 1899, the American Electrician Company published Miller's book, American Telephone Practice. At 458 pages including many dozens of illustrations, it detailed nearly everything known about telephone technology at the time. Two more editions followed within one year in 1900. In 1905, a final edition, the fourth, was published by McGraw-Hill Book Company. The edition, "enlarged and entirely rewritten", grew to 888 pages.

Philanthropy
Credited in 1928, along with F.R. Welles and Charles A. Brown, with donating 100 acres of land that would become Pilot Butte State Scenic View in Bend, Oregon.

Death
Miller died on November 22, 1933, in Pasadena, California, at the age of 63.

Pencil-beam scanning. Pencil beam scanning is the practice of steering a beam of radiation or charged particles across an object. It is often used in proton therapy, to reduce unnecessary radiation exposure to surrounding non-cancerous cells.

Ionizing radiation

Ionizing radiation photons or x-rays (IMRT) use pencil beam scanning to precisely target a tumor. Photon pencil beam scans are defined as crossing of two beams to a fine point.

Charged particles
 
Several charged particles devices used with Proton therapy cancer centers use pencil beam scanning. The newer proton therapy machines use a pencil beam scanning technology.
This technique is also called spot scanning. The Paul Scherrer Institute was the developer of spot beam.

Intensity Modulated Proton Therapy

Varian's IMPT system uses all pencil-beam controlled protons where the beam intensity can also be controlled at this small level. This can be done by going back and forth over a previously radiated area during the same radiation session.

Aerobeacon. An aerobeacon is a light assembly used to create a fixed or flashing signal visible over long distances. It consists of a high intensity electric lamp mounted with a focusing device in a cylindrical housing, which usually is rotated on a vertical axis by an electric motor. The sweep of the narrow beam thus produced gives the flashing effect. Aerobeacons were originally developed for aviation use, mostly as aerodrome beacons, but they also saw extensive use in lighthouses. They were far less expensive to manufacture and maintain than classic glass Fresnel lenses, and much more durable; they could be mounted and exposed to the weather. Historic models include the DCB-24, which used a single parabolic reflector; the DCB-224, a double-beamed version of the DCB-24; and the DCB-36, which used a system of plastic Fresnel type lenses. Manufacturers included Carlisle & Finch in Cincinnati and the Crouse-Hinds Company in Syracuse, New York. Aerobeacons have replaced fragile glass Fresnel lenses in many lighthouses and are still widely used in other applications.

DCB-224

The model DCB-224 is a high-power spotlight designed and built by Carlisle & Finch.  Originally intended for use as an aerodrome beacon, it was also widely used in marine lighthouses.

Depending on the type of bulb installed, the beam could be seen for .  The unit consists of a 25-inch aluminum housing with a parabolic reflector.  An electric motor and gearbox drives the optical unit's rotation.  They can optionally be fitted with a CG-2P automatic bulb changer.

The letters DCB stand for Directional Code Beacon.

Dickson Dam. Dickson Dam is a flow-regulation dam constructed in 1983 which impounded the Red Deer River creating a reservoir known as Gleniffer Lake. The dam is  west of the town of Innisfail and  southwest of the city of Red Deer. The dam was created to control for floods and low winter flows, to improve quality of the river, to create a recreational resource and to provide a reliable, year-round water supply sufficient for future industrial, regional and municipal growth.

Generation
All water control structures at the site, including the dam, intake, headgates, and spillway, are owned by the Province of Alberta and administered by Alberta Environment and Water. Algonquin Power owns a small hydropower station that was added to the dam.  It consists of three 5 MW Barber turbines with Ideal Generators. Commercial operations began on January 16, 1992. Water management of the reservoir is directed by the provincial Ministry of Environment and Water. 

Under the Dickson Power Purchase Agreement signed in 1990, all electrical power generated by the facility was sold to TransAlta Utilities Corporation. The 20-year contract expired on January 16, 2012.

Low reservoir water levels were a concern in 2010.

Gleniffer Reservoir Provincial Recreation Area
In the summer of 2009, Alberta Tourism, Parks and Recreation consolidated six provincial recreation areas (PRAs) at Dickson Dam and around Gleniffer Lake  (Dickson Dam–Cottonwood PRA, Dickson Dam–Dickson Point PRA, Dickson Dam–North Dyke PRA, Dickson Dam–South Dyke PRA, Dickson Dam–North Valley PRA, Dickson Dam–South Valley PRA) into one PRA renamed Gleniffer Reservoir PRA. Motorboating, waterskiing, swimming, and sailboarding are allowed. There are rainbow trout in a trout pond. Northern pike, walleye, mountain whitefish, and brown trout are also found nearby.

Globally asynchronous locally synchronous. Globally asynchronous locally synchronous (GALS), in electronics, is an architecture for designing electronic circuits that addresses the problem of safe and reliable data transfer between independent clock domains. GALS is a model of computation that emerged in the 1980s. It allows to design computer systems consisting of several synchronous islands (using synchronous programming for each such island) interacting with other islands using asynchronous communication, e.g. with FIFOs.

Details
A GALS circuit consists of a set of locally synchronous modules communicating with each other via asynchronous wrappers. Each synchronous subsystem ("clock domain") can run on its own independent clock (frequency). Advantages include much lower electromagnetic interference (EMI). The CMOS circuit (logic gates) requires relatively large supply current when changing state from 0 to 1. These changes are aggregated for synchronous circuit as most changes are initialised by an active clock edge. Therefore, large spikes on supply current occur at active clock edges. These spikes can cause large electromagnetic interference, and may lead to circuit malfunction. In order to limit these spikes large number of decoupling capacitors are used. Another solution is to use a GALS design style, i.e. design (locally) is synchronous (thus easier to be designed than asynchronous circuit) but globally asynchronous, i.e. there are different (e.g. phase shifted, rising and falling active edge) clock signal regimes thus supply current spikes do not aggregate at the same time. Consequently, GALS design style is often used in system on a chip (SoC). It is especially used in network on a chip (NoC) architectures for SoCs.

Some larger GALS circuits contain multiple CPUs.
Generally each CPU in such an asynchronous array of simple processors has its own independent oscillator.
That oscillator can be halted when there's no work for its CPU to do.

In some cases each CPU is further divided into smaller modules, each with their own independent clock,
or in a few cases no clock at all ().

Friction drilling. Friction drilling is a method of making holes in metal in which the material is pushed out of the way with the aid of heat from friction. The process is also called thermal drilling, flow drilling, form drilling, or friction stir drilling.

Friction drilling is commonly used on bicycle frames, heat exchangers, and to create holes for mounting bearings.

History
In 1923, the Frenchman Jean Claude de Valière tried making a tool that could make holes in metal by friction heat, instead of by machining. It was only a moderate success, because at that time the right materials were not yet available. Moreover, he hadn't yet discovered the right shape for this kind of tool.

It was not until the 1980s that a useful tool could be produced.

Principle
Friction drilling uses a conical bit made of very heat-resistant material such as cemented carbide. This device is pressed against a target material with both high rotational speed and high pressure. That way, there is a high local production of heat which softens the object, making it plastic. The tool then "sinks" through the object, making a hole in it. Lubricants help prevent work-material from adhering to the bit. Unlike drilling, material that is flowed is not lost but it forms a sleeve around the hole. The length of that sleeve is up to 3 times the original thickness of the material. The presence of this metal lip around hole edges makes connections stronger.

Several options are available with this technology.  Bits may include a cutting device that removes the typical "collar" of plastified material that flows upwards, so that an even top surface is the result. Drilled starter holes may be used to reduce the required axial force and to leave a smooth finish in the bushing’s lower edge. Internal screw threads may be cut with taps or rolled with dies.

Advantages
 Very quick process (2 to 6 seconds)
 The process reshapes all material so that no material is lost. The excess material forms a sleeve that is about 3 times longer than the original thickness of the target material, which makes it possible to make very strong bolt joints in thin material.
 It is a clean process because no litter (particles) is produced.
 No access needed to back of workpiece, as with press-in or self-clinching hardware.
 More reliable and faster than rivet nuts (an alternative that also does not require access to back of workpiece).
 Works in almost all kinds of metal.

Disadvantages
 Friction drilling is not possible in massive material since displaced metal must be able to flow somewhere. Maximum material thickness is typically half of the hole diameter with bit manufacturers providing specific guidance.
 The target material must be able to withstand the added heat. Materials that have been painted, plastic coated, galvanized, or heat treated are often unsuitable for this process.
 Requires higher motor capacity and rotational speed than conventional drills.
