  • Publication number: 20190347284
    Abstract: The present disclosure is directed towards systems and methods for detecting deviations from a standard document in a document being analyzed. The inventive systems and methods include performing a first level analysis to detect portions of a standard that are identical to, similar to, deleted from, and added to a document being evaluated. A second level analysis may be applied to those portions of the standard that are similar, but not identical to, portions of the document being evaluated to assist a user in identifying similarities and differences between the two portions of text.

  • Publication number: 20190265703
    Abstract: A system and method for an on-demand shuttle, bus, or taxi service able to operate on private and public roads provides situational awareness and confidence displays. The shuttle may include ISO 26262 Level 4 or Level 5 functionality and can vary the route dynamically on-demand, and/or follow a predefined route or virtual rail. The shuttle is able to stop at any predetermined station along the route. The system allows passengers to request rides and interact with the system via a variety of interfaces, including without limitation a mobile device, desktop computer, or kiosks. Each shuttle preferably includes an in-vehicle controller, which preferably is an AI Supercomputer designed and optimized for autonomous vehicle functionality, with computer vision, deep learning, and real time ray tracing accelerators. An AI Dispatcher performs AI simulations to optimize system performance according to operator-specified system parameters.

  • Publication number: 20190159729
    Abstract: Provided is a flex-PCB catheter device that is configured to be inserted into a body lumen. The flex-PCB catheter comprises an elongate shaft, an expandable assembly, a flexible printed circuit board (flex-PCB) substrate, a plurality of electronic components and a plurality of communication paths. The elongate shaft comprises a proximal end and a distal end. The expandable assembly is configured to transition from a radially compact state to a radially expanded state. The plurality of electronic elements are coupled to the flex-PCB substrate and are configured to receive and/or transmit an electric signal. The plurality of communication paths are positioned on and/or within the flex-PCB substrate. The communication paths selectively couple the plurality of electronic elements to a plurality of electrical contacts configured to electrically connect to an electronic module configured to process the electrical signal. The flex-PCB substrate can have multiple layers, including one or more metallic layers.

  • Patent number: 9397445
    Abstract: An electrical connector system is provided that includes a plug connector, a connector position assurance (CPA) device, and a header connector. The plug connector includes a housing and a deflectable primary latch that extends from the housing. The housing includes a lug protruding therefrom. The CPA device is mounted to the plug connector and is configured to translate relative to the plug connector. The CPA device includes a deflectable retention latch having a head at a distal end thereof. The header connector has a latching surface that engages the primary latch of the plug connector. When the plug connector mates to the header connector, a tab of the header connector deflects the retention latch of the CPA device to allow the CPA device to be translated in a locking direction beyond the lug to a locked position. The head of the retention latch blocks deflection of the primary latch.
