International Classification:

G06F 7/00

US Classification:

701 33

Abstract:

A system for diagnosing vehicle problems that may include a client device and central device. The client device may include a connector to connect to a vehicle and a vehicle interface to send and receive information from the vehicle. The client may also include an input/output system, a processor, and a communication system to communicate with the central device. The client device may capture a vehicle identification number (VIN) and may transmit the captured VIN along with geographic information to the central device. In response to received instructions from the central device, the client device may passively capture diagnostic information from the vehicle and transmit the diagnostic information to the central device. In response to the diagnostic information, the central device may transmit further instructions to the client device.

G06F 16/182
G06F 3/06

Abstract:

Certain embodiments described herein are directed to methods and systems for adding one or more nodes to a first cluster including a first node in a computer system. A method performed by the first node comprises receiving a first request from a second node to join the first cluster. The method also comprises retrieving a first cluster configuration associated with the first cluster from a distributed database through a first database server (DBS) and creating a second cluster configuration using the first cluster configuration and information received from the second node as part of the request. The method further comprises populating a first one or more local trust stores of a first one or more processes executing on the first node with a second one or more security certificates of a second one or more processes executing on the second node. The method further comprises writing the second cluster configuration to the distributed database and returning the second cluster configuration to the second node.
