US Patent:

60634367, May 16, 2000

Filed:

Jul 10, 1998

Appl. No.:

9/113673

Inventors:

James M. Pavell - Thousand Oaks CA
Chong C. Lee - Calabasas CA
Alan F. Stewart - Thousand Oaks CA

Assignee:

Litton Systems, Inc. - Woodland Hills CA

International Classification:

B05D 136
C23C 1404
C23C 1446

US Classification:

427162

Abstract:

The uniformity of individual layers of multiple coating materials deposited on a substrate in a vacuum deposition process (such as for manufacturing mirrors for use in ring laser gyroscopes) is improved by an apparatus and method that include changing the masks placed in front of the substrate upon which the coating materials are to be deposited. Separate masks are tuned for each particular coating material to compensate for the unique plume shape of the material, and provide a uniform deposition of that particular coating material. Each mask is positioned in front of the substrate when the material for which the mask has been tuned is being deposited. The masks are changed when the coating material is changed, without venting the chamber.

Appl. No.:

15/818910

Inventors:

- DALLAS TX, US
Chong Lee - Allen TX, US

International Classification:

G06F 21/36

Abstract:

A method and associated computing device. A first arrangement of numeric characters - is displayed, on a touch screen of the computing device, for an entry of a confidential sequence of numeric characters by a user during display of the first arrangement of the numeric characters - in ten respective regions of the touch screen. Each region includes (i) a unique numeric character and (ii) a graphical design that does not include the unique numeric character. The graphical design in each region is a different graphical design in each region. Each region has a closed exterior boundary and is totally filled with the graphical design consisting of a background pattern or no pattern. A graphical characteristic is instantiated differently for each numeric character displayed in the first arrangement. User touches are received on the displayed first arrangement of the confidential sequence of numeric characters to authenticate or authorize the user.

Abstract:

A method and associated computing device, A first arrangement of numeric characters 0-9 is displayed, on a touch screen of the computing device, for an entry of a confidential sequence of numeric characters by a user during display of the first arrangement of the numeric characters 0-9 in ten respective regions of the touch screen. Each region includes (i) a unique numeric character and (ii) a graphical design that does not include the unique numeric character.

Inventors:

- Dallas TX, US
Chong Lee - Allen TX, US

Assignee:

Softlayer Technologies, Inc. - Dallas TX

International Classification:

G06F 21/60

US Classification:

713184

Abstract:

A method and system for performing a security authentication. A name of a user, N sequences of digits, and encrypted values respectively corresponding to the digits in the N sequences are transmitted to a destination device. Each sequence includes a same M unique digits and begins with a different digit, wherein N≧2 and M≧3. N encrypted values of the transmitted encrypted values are received, wherein an Ireceived encrypted value of the N received encrypted values corresponds to one of the digits selected by the user, at an electronic device, from a respective Isequence of the N sequences (I=1, 2, . . . , N). N digits respectively corresponding to the received N encrypted values are determined. The determined N digits form a number matching a PIN associated with the name of the user, which authenticates the user to access a resource.
