  • Publication number: 20230417857
    Abstract: A computer includes a processor and a memory, and the memory stores instructions executable to receive range data from a plurality of ultrasonic sensors on a vehicle, determine two ellipses from respective pulses of the range datadetermine a plurality of intersections of the two ellipses, exclude a subset of the intersections, and actuate a component of the vehicle based on the nonexcluded intersections. The ultrasonic sensors have respective fields of view, the fields of view overlap, and the range data includes distances traveled by pulses emitted by the ultrasonic sensors and received by the ultrasonic sensors. Each pulse is emitted by a different one of the ultrasonic sensors than received that pulse. Excluding the subset of the intersections is based on the fields of view.

  • Patent number: 11087147
    Abstract: A computer, including a processor and a memory, the memory including instructions to be executed by the processor to generate a first map, based on vehicle sensor data, of a free space on a roadway in which a first vehicle can operate without contacting roadway edges and non-stationary objects on the roadway, the first map including roadway lane markings in an environment around the first vehicle, wherein the non-stationary objects include one or more second vehicles and generate a second map of free space in the environment around the first vehicle by determining B-splines corresponding to first roadway lanes based on the roadway lane markings and the roadway edges included in the first map. The instructions include further instructions to determine second roadway lanes based on determining locations of the non-stationary objects, determine combined roadway lanes based on the first roadway lanes and the second roadway lanes and operate the first vehicle based on the combined roadway lanes.

  • Publication number: 20080300898
    Abstract: A document processing device is provided. A device service is configured to generate information concerning a document processed by the document processing device. A client interface is included in the device service and is configured to perform at least one of (a) publishing an event to a plurality of clients based on at least one of a status of the document processing device and the information and (b) providing an instruction to the document processing device based on a message from one of the plurality of clients. One or more application services are in selective communication with the device service and at least one of the clients.

  • Patent number: 6513070
    Abstract: A method and configuration for interprocessor communication provides reduced latency and complexity, as well as the ability to simultaneously transfer different types of data. A multi-channel interface is disposed between a slave processor and a master processor, wherein the multi-channel interface has a low-latency channel for transferring low-latency information and a high-throughput channel for transferring high-throughput information. The master processor interrupts the slave processor when the master processor has control information to transfer to the slave processor. Interrupt driven notification and the multi-channel interface provide reliable, high-speed communication between dissimilar processors.
