Patent number: 10002571Abstract: The system for coordinated color control of LCD backlight and filters comprises a display pixel, a light source driver, a filter driver, and a processor. The light source driver sets a backlight color and a backlight intensity level for the display pixel. The filter driver sets an array of filter levels for three or more filters for the display pixel. The processor is configured to determine the backlight color and the backlight intensity level and the array of filter levels to target a desired color and intensity for the display pixel. The array of filter levels is determined based at least in part on the backlight color and the backlight intensity level.Type: GrantFiled: February 22, 2011Date of Patent: June 19, 2018Assignee: Zulch Laboratories, Inc.Inventor: Richard C.

Patent number: 8665296Abstract: A system for generating a colored light comprises a set of illuminant types and a processor. The set of illuminant types is associated with a chromaticity gamut, and the set of illuminant types comprises at least five illuminant types that are each associated with an illuminant type hue angle. The processor is configured to determine, based at least in part on a mapping, a sequence of one or more output level sets that are associated with changing a first generated colored light associated with a first color coordinate to a second generated colored light associated with a second color coordinate. The mapping comprises associating each color coordinate with an output level set that uses a set of hue-adjacent illuminant types. Hue-adjacent illuminant types comprise a group of illuminant types that are determined to be adjacent in a circular ordered list of illuminant types which is circularly ordered according to the illuminant type hue angle.Type: GrantFiled: April 30, 2009Date of Patent: March 4, 2014Assignee: Zulch Laboratories, Inc.Inventor: Richard C.

Patent number: 8330392Abstract: A system for changing a light source intensity comprises a controller, an input interface, and a memory. The input interface is configured to receive a command intensity for a light source, wherein the light source has a current intensity, and wherein an intensity of the light source is ramped toward the command intensity from the current intensity automatically. The controller is configured to determine a non-linear curve for the intensity of the light source, wherein at least a portion of the non-linear curve includes a beginning slope that is steeper than an end slope and to cause a change of a light source intensity by ramping over a time interval, wherein the light source intensity targets conforming to the non-linear curve for the intensity of the light source. The memory is coupled to the processor and configured to store an intensity value.Type: GrantFiled: June 15, 2011Date of Patent: December 11, 2012Assignee: Zulch Laboratories, Inc.Inventor: Richard C.

Patent number: 7994732Abstract: Changing light source intensity is disclosed. A command intensity is received for a light source, wherein the light source has a current intensity, and wherein a starting intensity is equal to the current intensity when the command is received. A sequence of at least three steps in intensity for the light source is determined, wherein each step of the sequence is used to change the light source intensity from the starting intensity toward the command intensity, and wherein each of the at least three steps of the sequence are progressively smaller. A light source intensity change is caused, wherein the sequence of the at least three steps in intensity for the light source are added each in turn to the current intensity with a time interval occurring between each of the at least three steps of the sequence.Type: GrantFiled: May 31, 2007Date of Patent: August 9, 2011Assignee: Zulch Laboratories, Inc.Inventor: Richard C.

Patent number: 7966513Abstract: A method of automatically classifying clients into different backup policy groups according to pre-selected criteria, such as type of client, whether the client is a server, a desktop or a mobile computer, the department or business unit, or even the user. The method uses information obtained from the client itself to classify the client. This information includes the kind of processor platform and operating system in the client, the type and version of software being run, and whether the client has a battery, indicating that it is a mobile computer. Other information that can be used to classify the client for backup may be obtained from information that identifies the user, the department to which the client is assigned, and the location in which it is used. The process enables a mobile client traveling to another site of an enterprise to connect to a local LAN of the enterprise and be authenticated for backup, and to be automatically assigned an appropriate backup classification.Type: GrantFiled: February 3, 2006Date of Patent: June 21, 2011Assignee: EMC CorporationInventors: Asit A. Desai, Richard C. Zulch

Patent number: 7890746Abstract: A method of automatically authenticating clients on a computer system network enables clients on the network to be automatically logged in and added to a backup database and assigned for backup. The method employs a public key/private key encryption system in which clients have a public key and the backup server has a private key. The backup server interrogates new clients to determine client status and whether the client supports the public key/private key certificate. If it does, the backup server uses key values from the client decrypted using its private key to generate encryption keys which are employed in an algorithm for securely communicating with the client to log the client into a backup database. Otherwise, the backup server uses a password entered by a user in the client for generating the encryption keys. Additionally, the method enables backup software and public keys to be automatically push installed on the clients.Type: GrantFiled: February 3, 2006Date of Patent: February 15, 2011Assignee: EMC CorporationInventors: Asit A.

Patent number: 5966730Abstract: A backup system is operated in accordance with a server or intelligent storage data controller containing a pre-written script governing a backup protocol. This script designates the possible source of data for backup that could become visible on the network and the possible storage sets that may be available in the storage repository. Preferably, the script also contains a timetable for when the script should be active, and wrap up interval of time for intelligently terminating a particular backup operation. In operation, the total number of accessible data sources (usually computers) and the total number of storage media destinations (for example available tapes mounted in tape drives) are generated to list possible source to storage paths. Utilizing the script, the possible source to storage paths are prioritized with the least recently backed up source as dated by the available media having first priority for backup.Type: GrantFiled: October 30, 1996Date of Patent: October 12, 1999Assignee: Dantz Development CorporationInventor: Richard C.

Patent number: 5150473Abstract: A data archive format is disclosed for archiving computer information taken from computer sessions, each session being of the form that includes a so-called "root directory" with appropriate branches leading to each discrete file or subfile within the computer session. The archive format includes the transfer of data to an archive media member, which archive media member can alternatively be addressable or sequential memory and can be recordable in either a rewriteable or right once manner. When data is archieved, a separate and resident archived directory is created in the immediate memory of the computer having data to be archived, the purpose of this separate and resident directory being to maintain high speed during reading and writing of the archived data.Type: GrantFiled: January 16, 1990Date of Patent: September 22, 1992Assignee: Dantz Development CorporationInventor: Richard C.
