4797 Ako

4797 Ako, provisional designation 1989 SJ, is a stony asteroid from the inner regions of the asteroid belt, about 6 kilometers in diameter. It was discovered by the Japanese astronomers Toshiro Nomura and Kōyō Kawanishi at the Minami-Oda Observatory, Japan, on 30 September 1989.

The asteroid orbits the Sun at a distance of 2.0–2.9 AU once every 3 years and 9 months (1,369 days). Its orbit shows an eccentricity of 0.18 and is tilted by 2 degrees to the plane of the ecliptic. It has a rotation period of 4.1 hours and an albedo of 0.11, according to the U.S. Wide-field Infrared Survey Explorer survey with its subsequent NEOWISE mission. However, the Collaborative Asteroid Lightcurve Link (CALL) assumes a higher albedo of 0.21, which is typical for a stony asteroid with a S-type spectrum. As a consequence, CALL calculates that the asteroid measures only 4 kilometers in diameter, as the higher the body's albedo (reflectivity), the lower its diameter for a given absolute magnitude (brightness).

Chess

Chess is a two-player board game played on a chessboard, a checkered gameboard with 64 squares arranged in an eight-by-eight grid. Chess is played by millions of people worldwide, both amateurs and professionals.

Each player begins the game with 16 pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns. Each of the six piece types moves differently. The most powerful piece is the queen and the least powerful piece is the pawn. The objective is to 'checkmate' the opponent's king by placing it under an inescapable threat of capture. To this end, a player's pieces are used to attack and capture the opponent's pieces, while supporting their own. In addition to checkmate, the game can be won by voluntary resignation by the opponent, which typically occurs when too much material is lost, or if checkmate appears unavoidable. A game may also result in a draw in several ways.

Chess is believed to have originated in India, some time before the 7th century; the Indian game of chaturanga is also the likely ancestor of xiangqi and shogi. The pieces took on their current powers in Spain in the late 15th century; the rules were finally standardized in the 19th century.

Power!

Power! (known as Critical Mass in Europe) is a computer game developed by Simon Francis in 1985 for the Amstrad CPC, Commodore 64 and ZX Spectrum.

Plot

The player operates a rocket-powered hovercraft whose mission is to destroy an enemy transfer beam that is protected not only by long-distance enemy raiders and mines, but also molecular disorientation that sucks the energy from the player's attack craft.

Gameplay

The player may control the hovercraft in either a normal joystick operational mode or with vectored movement. When the player pushes forward on the joystick, the hovercraft accelerates, and when pulling back on the joystick, speed decreases.

Reception

In 1988, Dragon reviewed Power!, and gave the game 4 out of 5 stars.

PoweredUSB

PoweredUSB, also known as Retail USB, USB PlusPower, and USB +Power, is an addition to the Universal Serial Bus standard that allows for higher-power devices to obtain power through their USB host instead of requiring an independent power supply or external AC adapter. It is mostly used in point-of-sale equipment, such as receipt printers and barcode readers.

History

PoweredUSB, as a proprietary variant of USB, was developed and proposed by IBM, Berg (now FCI), NCR and Microsoft between 1998 and 1999, with the last revision (0.8g) issued in 2004. The specification is not endorsed by the USB Implementers Forum (USB-IF). IBM, who owns patents to PoweredUSB, charges a licensing fee for its use.

PoweredUSB was licensed by Hewlett-Packard, Cyberdata, Fujitsu, Wincor and others.

Implementation

PoweredUSB uses a more complex connector than standard USB, maintaining the standard USB 1.x/2.0 interface for data communications and adding a second connector for power. Physically, it is essentially two connectors stacked such that the bottom connector accepts a standard USB plug and the top connector takes a power plug.
