G06F 11/30

US Classification:

713320, 713340, 714 14

Abstract:

A signal suitable for signaling a computer system to reduce power consumption is generated from a plurality of power supplies. The signal is asserted when at least one of the power supplies of the plurality of power supplies signals impairment, and at least one of the power supplies of the plurality of power supplies signals that the power supply is supplying current above a threshold level.

Filed:

Jun 26, 1989

Appl. No.:

7/371875

Inventors:

Stephen E. Horvath - Roseville CA

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

G09G 104
H01J 2958

US Classification:

315382

Abstract:

A circuit within a display monitor is used to generate a focal voltage used to vary the focal length of an electron beam of a cathode ray tube. The circuit utilizes horizontal current placed on a horizontal deflection yoke of the cathode ray tube and utilizes vertical current placed on a vertical deflection yoke of the cathode ray tube. The circuit includes a horizontal capacitor, a vertical capacitor, a first amplifier, a second and a summing device. The horizontal capacitor is connected to the horizontal deflection yoke. Similarly, the vertical capacitor is connected to the vertical deflection yoke. The voltages across each of the vertical capacitor and the horizontal capacitor are amplified and summed to obtained the focal voltage.

Filed:

Jun 24, 1998

Appl. No.:

9/104485

Inventors:

Stephen Ejner Horvath - Roseville CA

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

H02H 324
H03K 1722

US Classification:

327198

Abstract:

An apparatus for supervising input voltages of a multi-rail power supply includes a corresponding voltage detector unit electrically connected to each rail for ascertaining values of the input voltages of each rail. An output of each voltage detector unit is electrically connected at a wired-or node. A pull-up resistor is connected between the wired-or node and a power supply for pulling the voltage level of the wired-or node high. Circuitry generates a power-good signal responsive to the voltage of the wired-or node being greater than a predetermined threshold voltage.

Abstract:

The present disclosure is drawn to amorphous thin metal films and associated methods. Generally, an amorphous thin metal film can comprise a combination of four metals or metalloids including: 5 at % to 85 at % of a metalloid selected from the group of carbon, silicon, and boron; 5 at % to 85 at % of a first metal; 5 at % to 85 at % of a second metal; and 5 at % to 85 at % of a third metal wherein each metal is independently selected from the group of titanium, vanadium, chromium, cobalt, nickel, zirconium, niobium, molybdenum, rhodium, palladium, hafnium, tantalum, tungsten, iridium, and platinum, wherein the first metal, the second metal, and the third metal are different metals. Typically, the four elements account for at least 70 at % of the amorphous thin metal film.
