The safety electric receptacle and plug by which the completion of an electrical circuit is impossible until the plug makes a rotation of lateral translation after inserting into receptacle is disclosed. The apparatus utilizes a plug on which two blade conductors make a perpendicular position with the plug. Two conductors in the receptacle are installed at the place where don't touch with the inserted plug directly at first. There are two implementations of this device. First, the inserted plug ...

A method of operating a solar power station solar power station including a solar panel assembly having multiple towers, a solar panel pivotally mounted to an upper end of each tower, and a control system. Each of the towers has multiple floors and is individually extendable from a bottom position to an extended position. The control system includes a main routine for operating the towers comprising a normal operation subroutine for selectively positioning the towers between the bottom position ...

A modular cord retractor apparatus includes a spring-driven reel and may be used with a range of different electrical appliances incorporating a dual conductor cord. Fixed and rotating electrical contact pairs provide power to the cord and reduce noise and wear. Rotating contacts are disposed at axially opposing ends of an axle assembly supporting the reel. Each rotating contact has a contact surface intersecting the axis and each fixed contact is mounted to a fixed reel mount. The axle assembly...

Provided are a method, system, and program for initializing a storage device. A pulse response profile is determined for a storage system in response to a series of signals generated to seek to a location in the storage system. A determination is made of a desired response trajectory for the storage system that optimizes seek performance. An adjustment vector is calculated based on the pulse and step response profiles and the desired response trajectory to optimize the pulse response profile. Th...

A solar power station includes a solar panel assembly, having a substantially planar solar panel, and first, second and third towers. Each of the towers includes multiple vertically stacked floors and a main bearing structure pivotally mounting the solar panel assembly to the tower upper end. Each of the floors includes an arrangement of robots that are connected to each vertically adjacent floor. At least some of the robots including hydraulic jacks. A controller selectively actuates the hydrau...

An online algorithm exchange is presented herein. The online algorithm exchange provides access to a plurality of coloring algorithms from any number of developers. Users can select a particular algorithm for use as well as specify particular color measurements as inputs thereto. The color measurements can be selected from a database at the algorithm exchange, or provided by the user from a client terminal.

A method of synthesis of (2S,3R,1'R)-stegobinone(I) using borane intermediates and methods for the use of stegobinone (I) for attracting beetles of the Anobium species.

A direct access storage device (DASD) servo control system detects a servo pattern recorded in multiple cells of a servo sector and compares the cell-to-cell readback signal independently of the position error signal (PES). A servo sector of the disk contains multiple servo identification cells such that a servo readback signal is generated for each cell. If the servo signal data from two successive cells of a single sector, or from the same cell of successive sectors, differs by an amount great...

Imido and amido substituted alkanohydroxamic acids reduce the levels of TNF.alpha. and inhibit phosphodiesterase in a mammal. A typical embodiment is 3-(3-cyclopentyloxy-4-methoxyphenyl)-N-hydroxy-3-phthalimidopropionamide.

A direct access storage device that (DASD) includes a sector servo control system that controls disk write operations by receiving a servo pattern readback signal in a sector, determining track centering for that sector, and generating a write inhibit signal before any write operations are initiated for that sector. The servo control system is able to make write inhibit decisions without software processing delays, enabling the system to produce a write inhibit signal quickly after an off-track ...
