Abstract: A medical system includes a display for displaying an image and an analysis package operatively connected to the image display. The analysis package provides a user the ability to create a comprehensive report of all system functionality using simulated input from an exhaustive database of system input device values and user input values.

Abstract: A distributed diagnostic imaging system and method includes a data processor coupled to a variety of diagnostic imaging components through a network. The diagnostic imaging components include acquisition devices that are used to obtain diagnostic imaging signals, displays on which obtained images can be viewed, and control units that are used with either acquisition units or displays to control the manner in which an image is obtained or displayed. The distributed nature of the system makes it relatively easy and inexpensive to upgrade or modify individual imaging components, and allows the businesses of selling, distributing, and upgrading an imaging lab, and obtaining and reviewing diagnostic images to be conducted in a novel manner, such as by costing an imaging procedure on a “per use” or “per imaging application” basis.

Abstract: An ultrasound imaging system includes a video processor receiving coherent echo signals from a beamformer. The video processor converts the coherent echo signals to image data, which are applied to a streaming digital video processor. The system also includes an ECG monitor and processor that obtains an ECG signal and uses the signal to provide heart cycle data indicative of the beginning and end of each of the plurality of heart cycles. The streaming digital video processor converts the image data into streaming digital data, which are divided into the heart cycle sections as indicated by the heart cycle data. The system also includes a digital video disk recorder that records a digital video disk containing the digital video data divided into chapters containing respective heart cycle sections. The recorder may also record chapters of ECG data derived from the ECG signal along with the digital video data.

Abstract: A term-by-document (or part-by-collection) matrix can be used to index documents (or collections) for information retrieval applications. Reducing the rank of the indexing matrix can further reduce the complexity of information retrieval. A method for index matrix rank reduction can involve computing a singular value decomposition and then retaining singular values based on the singular values corresponding to singular values of multiple topics. The expected singular values corresponding to a topic can be determined using the roots of a specially formed characteristic polynomial. The coefficients of the special characteristic polynomial can be based on computing the determinants of a Gram matrix of term (or part) probabilities, a method of recursion, or a method of recursion further weighted by the probability of document (or collection) lengths.

Abstract: A distributed diagnostic imaging system (62) and method includes a data processor coupled to a variety of diagnostic imaging components through a network (80). The diagnostic imaging components include acquisition devices (90) that are used to obtain diagnostic imaging signals, displays (98) on which obtained images can be viewed, and control units (94) that are used with either acquisition units (90) or displays (98) to control the manner in which an image is obtained or displayed. The distributed nature of the system (62) makes it relatively easy and inexpensive to upgrade or modify individual imaging components, and allows the businesses of selling, distributing, and upgrading an imaging lab, and obtaining and reviewing diagnostic images to be conducted in a novel manner, such as by costing an imaging procedure on a “per use” basis.

Abstract: Handbrake assembly for the wheelbarrow is normally "on" and comprises a brake lever pivoted to the wheelbarrow undercarriage. One end of the lever carries a shoe head, the other a fixture for the drive cable of a Bowden wire leading to a bicycle-type handbrake. A spring presses the brake shoe end of the lever so that it engages the wheel.
