Patent number: 9392332Abstract: A method and apparatus for exercising access control over television programs using a parental control user interface that has different functions is provided. The method requires a password to enter into a master mode for obtaining access to all the functions of the parental control user interface. Once in the master mode, the user may enter a criterion for blocking a television program from being viewed or recorded or the user can override an already blocked television program. If a user, not in the master mode, attempts to watch or record a program that meets the blocking criterion and the program does not meet the overriding criterion, a prompt is provided to the user to enter the password. Upon entering a correct password, the program is unblocked.Type: GrantFiled: December 12, 2013Date of Patent: July 12, 2016Assignee: Rovi Guides, Inc.Inventors: Wing P. Leung, Roy J. Mankovitz, Henry C. Yuen

Patent number: 8078031Abstract: A video tape indexing system in which program broadcast identification information is entered into the system for use in recording the program. When the program is recorded, the system stores indexing information in an index memory. The system monitors a broadcast channel for electronic program guide information that includes titles and usually channel, date, time and length for the titles. The system matches the channel, date, time and length information from the broadcast channel with the identification information entered for the program to be recorded. The title in the broadcast channel associated with the channel, date, time and length information is then associated with the indexing information for the program.Type: GrantFiled: April 27, 2009Date of Patent: December 13, 2011Assignee: Index Systems, Inc.Inventors: Henry C.

Publication number: 20030237088Abstract: A television control system automatically tunes a television set to receive and display a desired program telecast at a future time. This is done by keying in a PLUS CODE™ number defining the channel, time, day, and length (CTDL data) of the program or selecting the program from an on-screen program guide to capture the CTDL data from an EPG data base stored in memory. The CTDL data is stored in a stack memory until the time of the program. The microprocessor monitors the stack memory. The microprocessor tunes the television set to the channel on which the desired program is telecast and turns the television set on at the time of the desired program.Type: ApplicationFiled: April 21, 2003Publication date: December 25, 2003Applicant: Gemstar Development CorporationInventors: Douglas B.

Patent number: 5689057Abstract: Crater shaped bumps are made on a calibration disk which can be used for calibrating a PZT slider, the PZT slider in turn being used for detecting predetermined asperities on a production run magnetic disk. The crater shaped bumps emulate predetermined asperities of production run magnetic disks and especially asperities which are undesirable and would cause the production run disk to be discarded after testing by the PZT slider. Crater shaped bumps which emulate undesirable asperities on current production runs of magnetic disks have a diameter in the range of 10 to 25 .mu.m and a peripheral ridge with a height h.sub.r above a nominal surface of the calibration disk in the range of 75 to 120 nm. Close tolerance crater shaped bumps with this configuration can be made by impinging two or more pulses of laser energy on the same location of a calibration disk. By increasing the number of pulses the height of the peripheral ridge progressively increases.Type: GrantFiled: February 27, 1996Date of Patent: November 18, 1997Assignee: International Business Machines CorporationInventors: Peter Michael Baumgart, Karl A.

The crater shaped bumps have a diameter in the range of 10 to 25 .mu.m and a peripheral ridge with a height h.sub.r above a nominal surface of the calibration disk in the range of 75 to 120 nm. Close tolerance crater shaped bumps with this configuration can be made by impinging two or more pulses of laser energy on the same location of the disk. By increasing the number of pulses the height of the peripheral ridge progressively increases. By employing multiple pulses, the height of the peripheral ridge is increased while the diameter of the crater shaped bump stays substantially constant. Further, by employing multiple pulses diameters and heights of crater shaped bumps can be produced with close tolerances within a diameter range of 5 to 20 .mu.m and a height range of 2 to 120 nm.Type: GrantFiled: February 27, 1996Date of Patent: May 20, 1997Assignee: International Business Machines CorporationInventors: Peter M.

Patent number: 5595791Abstract: A process for creating an array of bumps to texture a brittle nonmetallic surface, such as a glass substrate for data recording disks. The texturing process uses a laser to provide pulses of proper energy fluence to the brittle glass surface to produce a plurality of raised bumps in the surface. The bump creation is accomplished without unwanted micro-cracking or ejection of surface material by limiting the laser pulse fluence to a value in a narrow operating region discovered below the abrupt thermal shock fluence threshold for the brittle nonmetallic surface material. The process is also applicable to other brittle surface textures, such as those intended for use as "stamping surfaces" for the contact reproduction of the negative of a surface pattern, such as an optical disk.Type: GrantFiled: May 31, 1995Date of Patent: January 21, 1997Assignee: International Business Machines CorporationInventors: Peter M.

Patent number: 5544775Abstract: A method is provided for making a high definition, high aspect ratio amorphous carbon element, such as a slider, which carries one or more magnetic heads in a disk drive. A special gaseous environment is provided during laser etching which results in virtually no redeposition of the etched material. The result is a carbon element which has good edge definition for establishing desirable flying characteristics of a slider. In a preferred embodiment the laser etching, which is preferably implemented by an excimer laser, is performed in an gaseous environment of oxygen saturated with water vapor at a pressure above ambient. Significant improvements were also realized with nitrogen saturated with water vapor at a pressure above ambient and steam at ambient pressure. High aspect ratios were achieved, namely slope angles of 50.degree. to 60.degree..Type: GrantFiled: December 22, 1994Date of Patent: August 13, 1996Assignee: International Business Machines CorporationInventors: Randall T.

Patent number: 5543852Abstract: Apparatus and methods are provided for inserting data into a vertical blanking interval (VBI) line of video frames. The method includes the steps of inserting first data into a first vertical blanking interval VBI line for a plurality of consecutive video frames, inserting second data into a second vertical blanking interval VBI line for a plurality of consecutive video frames, counting a number of consecutive video frames having first data inserted into the first vertical blanking interval VBI line, terminating the insertion of first data for a first number of video frames before again inserting first data into the first vertical blanking VBI interval line when the counted number of consecutive video frames into which first data is inserted into the first vertical blanking interval VBI line equals a second number, and repeating the steps.Type: GrantFiled: June 24, 1994Date of Patent: August 6, 1996Assignee: Index Systems, Inc.Inventors: Henry C.
