Abstract: An object-detection system for an automated vehicle includes an object-detector, a receiver, and a controller. The object-detector detects detectable-objects proximate to a host-vehicle. The receiver receives an indication of an object-presence from other-transmitters proximate to the host-vehicle. The controller is in communication with the object-detector and the receiver. The controller is configured to operate the host-vehicle to avoid interference with a hidden-object when the hidden-object is not detected by the object-detector and the object-presence is indicated by at least two instances of the other-transmitters.

Abstract: A learning system for an automated vehicle to learn local traffic customs includes a location-detector, and object-detector, and a controller. The location-detector indicates a location of a host-vehicle on a digital-map. The object-detector detects a lane-marking and other-vehicles proximate to the host-vehicle. The controller is in communication with the location-detector and the object-detector. The controller is configured to determine when an observed-behavior of the other-vehicles is not in accordance with the lane-marking present at the location, and operate the host-vehicle in accordance with the observed-behavior.

Abstract: An open-loop brake control system for an automated vehicle includes a brake-unit and a controller. The brake-unit varies brake-pressure to operate brakes of a host-vehicle. The controller is in communication with the brake-unit. The controller operates the brake-unit to an initial-pressure to initiate braking of the host-vehicle in accordance with a brake-model that characterizes vehicle-deceleration versus the initial-pressure based on a time-of-operation of the brakes.

Abstract: Systems and methods are described for performing Layered Belief LDPC decoding on received Standard Belief LDPC encoded data bursts. In on implementation, a receiver: demodulates a signal, the demodulated signal including a noise corrupted signal derived from a codeword encoded using standard belief LDPC encoding; converts the noise corrupted signal derived from the standard belief LDPC encoded codeword to a noise corrupted signal derived from a layered belief LDPC encoded codeword; and decodes the noise corrupted signal derived from the layered belief LDPC encoded codeword using a layered belief LDPC decoder. In further implementations, systems are described for reducing collisions in Layered Belief LDPC decoders that occur when multiple parity checks need the same soft decision at the same time. In these implementations, elements in an original LBD decoder table are rearranged to increase the distance between elements specifying the same location in a RAM where soft decisions are stored.

Abstract: An operation-security system for an automated vehicle includes an object-detector and a controller. The object-detector includes at least three sensors. Each sensor is one of a camera used to determine an image-location of an object proximate to a host-vehicle, a lidar-unit used to determine a lidar-location of the object proximate to the host-vehicle, and a radar-unit used to determine a radar-location of the object proximate to the host-vehicle. The controller is in communication with the at least three sensors. The controller is configured to determine a composite-location based on a comparison of locations indicated by the at least three sensors. Information from one sensor is ignored when a respective location indicated by the one sensor differs from the composite-location by greater than an error-threshold. If a remote sensor not on the host-vehicle is used, V2V or V2I communications may be used to communicate a location to the host-vehicle.

The controller is in communication with the digital-map and the imager-device. The controller issues an update-request to update the digital-map when the actual-position differs from the expected-position by greater than an error-threshold.

Abstract: A lane management system for operating an automated vehicle includes a navigation-device, a vehicle-detector, and a controller suitable for use on a host-vehicle. The navigation-device is used to determine a preferred-route to a destination of the host-vehicle.

Abstract: Systems, methods, and machine-readable media are disclosed to provide for auditing of events or access of resources in a distributed system. In one embodiment, auditing access of resources can comprise receiving from a client a request to access one or more of the resources. A sign-on identifier can be assigned to a user of the client requesting to access the resources. The user identifier and sign-on identifier can be provided to one or more applications managing the one or more resources requested by the client. The resources requested by the client can be accessed based on the request. A record of the access of the resources requested by the client can be logged in a repository. Based on these records and information relating to prohibited activity, a determination can be made as to whether a prohibited activity is being performed by one or more users.

Abstract: One embodiment of the present invention provides a system that facilitates security-enabled content caching. The system operates by first receiving a request from a user at a cache server for restricted content, wherein the cache server stores content for an application server. Next, the system determines if the restricted content is located on the cache server. If so, the system determines if the user is authorized to access the restricted content. If the user is authorized to access the restricted content, the system provides the restricted content to the user from the cache server. Providing the restricted content from the cache server eliminates the time consuming operations involved in requesting and receiving the restricted content from the application server.

Abstract: One embodiment of the present invention provides a system that provides access to an application-resource. During operation, the system receives a request to access an application-resource associated with an application, wherein the request is received at an application-server that hosts the application. The system then determines an authentication-level required to access the application-resource. Next, the system sends the required authentication-level to an authentication-server. In response, the system receives an authentication-response from the authentication-server. Next, the system determines if the authentication-response specifies that the user is authenticated to access the application-resource. If so, the system grants the user access to the application-resource. One embodiment of the present invention provides a system that provides an authentication-token associated with a lower authentication-level in response to an authentication-token associated with a higher authentication-level expiring.

Abstract: One embodiment of the present invention provides a system that facilitates end-to-end identity propagation to a backend-tier application that is not single sign-on enabled. During operation, the system receives request from a user at a middle-tier application to access private data from the backend-tier application. Upon receiving this request, the system redirects the user to a single sign-on server that verifies authentication credentials of the user. The middle-tier application then receives a token from the single sign-on server authorizing access to a backend-tier application. Next, the middle-tier application uses the token to access the private data from the backend-tier application, and then provides the private data to the user.

Abstract: One embodiment of the present invention provides a system that performs single sign-on to web applications using dynamic directives. The system operates by first receiving a request at an application to provide content to a user. In response to the request, the application provides public content to the user. Upon receiving a request from the user to access private content, the application sends a dynamic directive to a web module that can access a single sign-on server on behalf of the application, wherein the dynamic directive specifies that an authentication credential is required from the user. Next, the application allows the web module to request the authentication credential from the single sign-on server on behalf of the application. When the authentication credential is received from the single sign-on server, the application provides the private content to the user.
