International Classification:

G06Q 10/00

US Classification:

705 11, 705 10

Abstract:

In one aspect, the invention relates to a method for creating a supplier-rating matrix for rating services of a supplier. The method includes defining a plurality of job attributes each including a plurality of sub-attributes, each sub-attribute representing a range of job attribute values and defining a job attribute vector associated with the supplier, the job attribute vector including a plurality of dimensions each corresponding to a sub-attribute. The method further includes defining a plurality of performance metrics and defining a performance vector associated with the supplier, the performance vector including a plurality of dimensions each corresponding to a performance metric. The method further includes defining a initial values for the job attribute vector and the performance vector and generating a supplier rating matrix for the supplier by mathematically combining the job attribute vector and the performance vector.

Abstract:

A system for providing collision avoidance in underwater vehicles contains a spectral analysis module for determining expectation value of acoustic (incoherent) intensity. The system also contains an intercept time estimation module for: receiving continuous time series of a current incoherent acoustic intensity and low pass filtering the time series of the current incoherent acoustic intensity; estimating temporal intensity rate of change; determining an estimated time to collision for an approaching source; and performing statistical regression analysis resulting in an estimated time of potential collision and an uncertainty measure.

Abstract:

An interactive exercise apparatus engages a user's mind and body. The apparatus comprises a support structure for supporting a user. An exercise mechanism and a steering mechanism are proximal to the support structure. A simulated environment is generated by a computer and displayed on a display system. The user manipulates the exercise mechanism and the steering mechanism to freely navigate through the simulated environment. The computer monitors the exercise mechanism and the steering mechanism to determine user position in the simulated environment. The display is periodically updated by the computer to provide a continuous visual display of the user's position as the user travels through the simulated environment.
