Abstract:
A method for implementing a project for a customer. Business requirements are developed for the project and are reviewed for acceptability in accordance with Business Requirements Review (BRR) exit criteria. System requirements are developed for the project and are reviewed for acceptability in accordance with system requirements review (SRR) exit criteria. Component requirements are developed for the project and are reviewed for acceptability in accordance with Preliminary Design Review (PDR) exit criteria. The business requirements are decomposed into the system requirements. The system requirements are decomposed into the component requirements. A Requirements Traceability and Verification Matrix (RTVM) is generated when the business requirements are established. The RTVM is updated throughout the life of the project. The RTVM includes verification information relating to the business requirements, the system requirements, and the component requirements. The RTVM depicts hierarchical relationships between the business requirements, the system requirements, and the component requirements.
Abstract:
A computerized method for determining throughput includes generating a demand array of item orders and generating a supply array of manufacturing inventory. The method includes selecting an item order in the demand array, and matching manufacturing inventory in the supply array with the selected item order. The method also includes assigning a throughput value to the selected item order based on the matched manufacturing inventory.
Abstract:
A scanning monochromator system which uses a directly coupled stepper motor to drive a spectral-dispersion element. The spectral-dispersion element is directly coupled to the output shaft of the motor. The movement of the motor is controlled with an electronic circuit that controls the motor winding current. The circuit includes a power driven section, a pulse-width modulator section and a computer section. The power driven section switches electrical current through the motor windings and can produce a variable pulse-width ranging from 0 to 100 percent modulation. The pulse-width modulator section accepts values from the computer section and converts these values into variable pulse-width signals for use by the power driver section. The computer section supplies values to the pulse-width modulator section based upon requirements for the motor movement and position. The required motor position is determined by the type of spectral-dispersion element and the desired wavelength selection of the monochromator.
Abstract:
A portable or moveable carport is described. The carport as described herein is able to be quickly and easily set up and taken down while still shielding a vehicle from rain, snow and sun—the primary destroyers of automotive paint, body and interiors. The structure has at least four vertical legs supporting an A-frame roof structure. The vertical legs are anchored under the vehicle's four tires with adjustable plates which can be driven onto once the structure is assembled.
Abstract:
A perch system for use by an animal such as a cat is disclosed. The perch system is attachable to a generally vertical wall, such as in a residence, and includes a plurality of wall mounts that each include a rigid wall mounting plate and at least one rigid mounting post projecting therefrom. The perch system further includes at least one perch that includes at least one post attachment means fixed thereto for selectively attaching the perch to each mounting post of the at least one wall mount. At least one connector is adapted for selectively fixing the connector between the mounting posts of two adjacent wall mounts. An inside corner section may be included for fixing to an inside corner of the wall, and an outside corner section may be included for fixing to an outside corner of the wall.
