Title: Robust steady-state target calculation for model predictive control
Inventor: HAWKINS ROBERT B
IPC: G05B13/02
Filed: 1999-09-28
Abstract: A method and apparatus for steady-state target calculation that explicitly accounts for model uncertainty is disclosed. In accordance with one aspect of the invention, when model uncertainty is incorporated, the linear program associated with the steady-state target calculation can be recast as a highly structured nonlinear program. In accordance with another aspect of the invention, primal-dual interior point methods can be applied to take advantage of the resulting special structure. For a system having characteristic gain parameters G having a known uncertainty description, the present invention provides a method and apparatus for selecting steady-state targets for said system-manipulated variables such that all system-controlled variables will remain feasible at steady-state for all possible values of the parameters G within the known uncertainty description. A  nominal estimate ~ of the system parameters G is made, and in accordance with another aspect of the invention, the steady-state targets are selected such that when ~ = G, the system is driven to an operational steady-state in which the objective function is extremized.

Filed: 2001-05-04
Abstract: The present invention provides methods and systems for accessing a network URL  through a pre-assigned simplified network address, correlating to the URL, and for displaying the home page having the URL as its address. These methods and systems provide easier URL  and home page access because persons wanting to access the home page need only input the simplified network address, thereby avoiding the need to know and input the URL character string.  The simplified network addresses of the present invention include numbers. Methods are provided for selecting numbers for assignment to URLs. The URL and home page access and display methods of the present invention include: assigning a simplified network address such as a number to a URL, storing the URL and number conversion in a network accessible storage system, inputting the assigned number in a network accessible computer, communicating the inputted number to the storage system, converting the number to the URL, retrieving the home page corresponding to the URL and displaying the home page on the computer. Additionally, the invention provides methods for use in message passing operating systems wherein system level messages to specific objects are intercepted, creating an alias message. The invention further defines networked systems and methods for operating the networked systems that rely on the interception and rule-based modification of messages passing between system applications.

Title: Engine fuel delivery control system
Inventor: MILLS WAYNE LEE
IPC: F02D17/02
Filed: 2001-06-13
Abstract: A fuel delivery control system controls fuel delivery for an engine having a plurality of cylinders and a electronically controlled fuel injection unit for controlling fuel delivered to each cylinder in response to control signals generated by an electronic control unit.  The control unit, for each cylinder, determines an engine acceleration value derived from a crank position value generated by an engine crank position sensor, compares the acceleration value to a threshold value, and terminates fuel delivery to only the cylinders for which the comparison indicates unsatisfactory combustion, up to one half of the cylinders.  The control unit operates to deliver a normal amount of fuel to cylinders for which the comparison indicates satisfactory combustion, and to cylinders for which fuel delivery has been terminated for a pre-set maximum number of times.  The control system also includes a motoring mode in which fuel delivery to all the cylinders in terminated while the engine is operating.

Title: A method and system for performing permutations using permutation instructions based on modified omega and flip stages
Inventor: LEE RUBY B
IPC: G06F9/308
Filed: 2001-05-07
Abstract: The present invention provides permutation instructions which can be used in software executed in a programmable processor for solving permutation problems in cryptography, multimedia and other applications. The permute instructions are based on an omega-flip network comprising at least two stages in which each stage can perform the function of either an omega network stage or a flip network stage. Intermediate sequences of bits are defined that an initial sequence of bits from a source register are transformed into. Each intermediate sequence of bits is used as input to a subsequent permutation instruction. Permutation instructions are determined for permuting the initial source sequence of bits into one or more intermediate sequence of bits until a desired sequence is obtained. The intermediate sequences of bits are determined by configuration bits. The permutation instructions form a permutation instruction sequence, of at least one instruction. At most 21gr/m permutation instructions are used in the permutation instruction sequence, where r is the number of k-bit subwords to be permuted, and m is the number of network stages executed in one instruction. The permutation instructions can be used to permute k-bit subwords packed into an n-bit word, where k can be 1, 2, ..., or n bits, and k*r=n.
