In a redundant array of disks, the disks are divided into areas of different sizes, so that small amounts of data can be stored in an area of an appropriate size on a single disk, instead of being spread over multiple disks. A usage status table indicates which areas are in use. Check information is generated and stored only for areas indicated to be in use. When new check information is generated, it is therefore possible to omit the reading of unnecessary old data and old check information. Wh...

Dynamic translation is used during debugging of a computer application process. During runtime, the first application is dynamically translated to produce translated code. Debugging code, such as a conditional breakpoint, may then be added to the translated code.

A bus monitor system comprises eight identical programmable monitor circuits that are each connected to a monitored bus and to a local 16-bit event bus. There are three interfaces to the event bus within each monitor circuit. One interface asserts a predetermined bit pattern on the event bus when match conditions occur between bit patterns on the monitored bus and predetermined bit patterns stored in monitor circuit registers. A second interface asserts a signal on an external pin when bit patte...

Design optimization methods can be used to design concrete mixtures having optimized properties, including desired strength and slump at minimal cost. The design optimization methods use a computer-implemented process that is able to design and virtually "test" millions of hypothetical concrete compositions using mathematical algorithms that interrelate a number of variables that affect strength, slump, cost and other desired features. The design optimization procedure utilizes a constant K (or ...

A plurality of receptacles in an irrigation controller removably receive a plurality of modules. At least one station module is configured for insertion into a first one of the receptacles and is connectable to a corresponding solenoid actuated valve through a dedicated field valve line and common return line. The station module includes at least one switching device for selectively providing a first power signal that energizes the corresponding solenoid actuated valve. At least one encoder modu...

Methods of integrating computer products with pharmaceutical manufacturing hardware systems are described and disclosed herein. Consequently, the methods provide a means to perform validation and quality control on an integrated level whereby a pharmaceutical manufacturer can ensure data and product integrity and minimize cost.

To evaluate the adequacy of a profile model, an initial profile model is selected. The profile model includes profile model parameters to be measured in implementing types of process control to be used in controlling a fabrication process. A measurement of profile model parameters is obtained using a first metrology tool and the profile model. A measurement of the profile model parameters is obtained using a second metrology tool and the profile model. Statistical metric criteria are calculated ...

Content is generated on a host system based on real-time data from a controlled process collected over an internet from a customer's client machine tool control system. The real-time data is captured from the client machine tool by downloading software that manipulates controller functionality to perform a data capture trace predefined events and triggers. The captured data is retrieved by the host, which may generate content based on the data, or provide selective, authorized access to the data...

A protection system is provided that mitigates damage caused by slug flow in oil and gas production systems. The protection system opens or closes a choke valve based upon flow parameters such as the separator pressure and level, and the riser pressure. The choke valve position is calculated based upon a number of factors of the production system in order to maintain efficiency while providing safety.

A base-plane-height determining unit determines whether a base plane is formed with planes of different heights. A base-plane determining unit determines, when it is determined that the base plane is formed with the plural planes of different heights, whether to take the plural planes or a single plane as a basis. A height-limited-area-information creating unit creates, when it is determined to take the plural planes as the basis, height-limited-area information by taking different planes for di...
