摘要:
A method of manufacturing integrated circuits based on providing a test column of memory cells in the devices. A test control processor (100) and a test board (101) for gang testing of integrated circuits (00, 01, 10, 11, 20, ...). Cells in the test column are selected by a portion of the addresses which identifies a row in the main array on the device. A test is executed to determine a characteristic of the device and the results of that test are mapped to the portion of the address which identifies a row in the array. This produces a characteristic code address for the device which indicates the test results of the test. Access to the test column on the device is enabled and a bit is written in response to the characteristic code address in a memory cell on the test column. During manufacture the test column is read in order to classify the device according to the characteristic. This allows for storing in a look up format significant amounts of data about the characteristics of the device without requiring large amounts of memory on the device, and substantially relieving the testing system of a requirement for memory resources.

摘要:
A system and method for monitoring the conditions in a gas plasma processing system while varying or modulating the RF power (2A, 2B, 2C) supplied to the system, so that resulting signals of the electrical circuits of the system provide information regarding operational parameters of the system or the state of a process. Significant improvements in sensitivity and accuracy over conventional techniques are thereby achieved. In addition, the plasma processing system can be thoroughly tested and characterized before delivery, to allow more accurate monitoring by monitor controller (1) of and greater control over a process, thereby improving quality control/assurance of substrates (40) being produced by the system. The information obtained by the modulation technique can be displayed on a monitor screen, in order to allow an operator to accurately monitor the system/process and diagnose any problems with the system/process.

The system controls formation of wet stock (55) comprising fibers on a moving water permeable wire (13) of a de-watering machine that has a refiner (135) that is subject to a variable load and a headbox (10) having at least one slice (50), wherein each slice (50) has an aperture through which wet stock (55) is discharged at a stock jet speed onto the wire (13) that is moving at a wire (13) speed. A sheet of wet stock (55) moving a speed develops on the wire (13). The system includes: a) at least two water weight sensors (42A-42E) that are positioned adjacent to the wire wherein the at least two sensors (42A-42E) are positioned at different locations in the direction of movement of the wire (13) and upstream from a dry line (43) which develops during operation of the machine and the sensors (42A-42E) generate signals indicative of a water weight profile made up of a multiplicity of water weight measurements; and b) adjustability of at least one of the stock jet speed, sheet speed, wire speed, or refiner load to cause the water weight profile to match a preselected or optimal water weight profile.

Driving power for a vibrating device is provided at less than full level when the device is initially used. Power is gradually increased in successive steps after a selected number of uses in each step until full power is achieved. Also, a battery-energized driving signal for a vibrating device has a selected characteristic, such as duty cycle, which in set initially at less than an optimum value, when the battery is at full strength. As the battery discharges, the selected characteristic is adjusted toward optimum so as to compensate for reduction in the battery voltage and ensure full power output.

A method and system for customizing and distributing for user sites (17) is disclosed and includes gathering user profile information to create data objects based on individual user profile information. The data objects are stored locally in a group of user computer sites (12). Presentation logic objects based on the data objects are created to facilitate the creation of individual customized presentations, at the user sites (17). The data objects are stored locally at the user computer sites (12). Presentation media objects are broadcast to the computer sites (12). Certain ones of the media components of the media objects are selected in response to the individual presentation logic objects and the individual data objects to create customized presentations for the users at their user sites (17).
