Publication number: 20040107905Abstract: A substrate surface is plasma cleaned and silanized in a chamber. Plasma is generated in the chamber to clean the substrate surface. Gas containing an organosilane compound is introduced into the same chamber to silanized the cleaned surface. Water is deposited on the substrate surface to facilitate silane coupling reaction. A layer of covalently bonded silane molecules having functional groups is thus produced on the substrate surface. The substrate is then cured by a baking process.Type: ApplicationFiled: August 14, 2003Publication date: June 10, 2004Applicant: AST Products, Inc., a Delaware corporationInventor: Min-Shyan Sheu

Patent number: 6170024Abstract: A computer system having dual paths for controlling a peripheral device electrically associated with a host computer. The peripheral device is electrically connected to the host computer and to an independent control circuit. Control inputs for the peripheral device and data and/or control inputs for the host computer are generated by a keyboard or other input device and transmitted to an input controller which directs certain data and/or control inputs to the host computer for processing and directs certain peripheral device control inputs to a state machine for the generation of peripheral device control signals. In such a manner, the independent control circuit provides for the control of the peripheral device while the host computer may process data unrelated to the control of the peripheral device. In one aspect, control of the peripheral device may be effected by both the host computer and the independent control circuit.Type: GrantFiled: November 23, 1999Date of Patent: January 2, 2001Assignee: AST Research, Inc.Inventors: Carl K.

Patent number: 6100875Abstract: An apparatus and method emulates mouse pointer functions utilizing a keyboard having an additional special function key. When the special function key is depressed, designated keys on the keyboard are interpreted as "mouse keys" which may be used to direct a pointer on a computer screen in a manner similar to a conventional mouse pointer. In one embodiment, the keys used as cursor movement keys during normal operation are designated as "mouse keys" which effect the movement of the pointer on the screen when the special function key is depressed. In addition, other keys may be used as left and right mouse buttons and as mouse lock keys. In one embodiment, the pointer speed is gradually increased when the user continuously holds any of the cursor movement keys down for a preselected interval.Type: GrantFiled: December 28, 1993Date of Patent: August 8, 2000Assignee: AST Research, Inc.Inventors: Michael Ken Goodman, Charles Frederick Raasch, Farzad Noorbehesht

Patent number: 6074769Abstract: The invention concerns a method of generating electrical energy from biomass which is produced in a biomass-production module. The biomass is gassified in a reformer module to form a hydrogenous crude gas from which a purified gas with a higher hydrogen content is produced. Electrical energy is generated from the purified gas in a converter module. In this case, biomass with low sulfur and chlorine contents is produced by a suitable fertilizing of plants. The reformer module operates with at least one allothermic reformer, the dwell time of the biomass or crude gas in the reformer, and the temperature and pressure therein being set so that the alkali compounds can be removed from the reformer with any ash produced. Tar is gassified in the reformer to form carbon monoxide and hydrogen. A purified containing less than 1% carbon monoxide is produced in the crude gas processing module.Type: GrantFiled: April 2, 1997Date of Patent: June 13, 2000Assignee: Hannelore Binsmaier Nee Gallin-AstInventor: Wolf Johnssen

Patent number: 6064766Abstract: A keyboardless entry computer system includes a transparent input screen that generates positional information when contacted by a stylus, and a display screen mounted physically below the input screen such that a character that is displayed can be seen below the input screen. The system includes a computer that has been programmed to compile the positional information into Strokes, to calculate Stroke characteristics, and then compare the Stroke characteristics with those stored in a database in order to recognize the symbol drawn by the stylus. Key features of the system are: (1) transparent position sensing subsystem; (2) underlying display on which to mimic drawing of sensed positions and to show characters or symbols; (3) means to convert sensed positions first into plotted Points and then into recognized characters or symbols; and (4) means to "learn" to associate sensed input positions with a character or symbol.Type: GrantFiled: December 18, 1998Date of Patent: May 16, 2000Assignee: AST Research, Inc.Inventor: Ralph Sklarew

Patent number: 6035358Abstract: A computer processing unit (CPU) module is described. The present CPU module accommodates a CPU and includes a power supply, a power good detection circuit and a clock speed selector, all of which are integral to the CPU module. The power supply provides the CPU module the ability to convert power supplied to the CPU module to power as needed by the CPU. The power good detection circuit provides the CPU module the ability to notify the mother board of a power supply to the CPU which is below the operating voltage of the CPU (e.g., a power failure or insufficient voltage). The clock speed selector provides the CPU module the ability to automatically set the clock speed to that required by the CPU without modification to the BIOS stored on the mother board or changing components.Type: GrantFiled: October 13, 1998Date of Patent: March 7, 2000Assignee: AST Research, Inc.Inventor: Roy K.

Patent number: 5961613Abstract: A computer network includes a network server in communication with a plurality of user terminals. The network server includes disk drives which store data accessible via the user terminals. To increase power efficiency of the network server, the number of accesses to the disk drives is monitored and a histogram is generated to display the distribution of disk accesses over time. A network administrator subsequently selects time intervals to spin down one or more of the disk drives during periods of disk inactivity as depicted in the histogram. In a preferred embodiment, the network administrator uses the histogram for failure analysis to determine which disks are more likely to fail over long time periods.Type: GrantFiled: September 2, 1997Date of Patent: October 5, 1999Assignee: AST Research, Inc.Inventor: Richard M.
