Inventor: Ashley Elizabeth Micks
IPC: G06K9/00
Filed: 2016-10-11
Abstract: Methods and apparatus pertaining to a testbed for lane boundary detection in a virtual driving environment are provided. A method may involve generating, by a processor, a virtual driving environment comprising one or more driving lanes, a virtual vehicle (190), and one or more virtual sensors (191 193) mounted on the virtual vehicle configured to generate simulated data as the virtual vehicle traverses within the virtual environment. The method may also involve executing an algorithm to process the simulated data to detect the one or more driving lanes. The method may further involve recording an output of the algorithm. The method may additionally involve annotating the simulated data with the output of the algorithm. An advantage is that the simulated data is virtual data that is created without the time or expense required to collect such date from driving an actual car with actual sensors on real roads.

Title: Methods and devices for validating data in a blockchain network
Inventor: STEVEN PATRICK COUGHLAN
IPC: H04L9/32
Filed: 2020-06-26
Abstract: The invention provides a data structure for verifying Merkle proof data that includes an index position field for the location of the transaction within the ordered set of transactions within a block. The index enables determination of the left-hand or right-hand location of each calculated element when bottom-up tracing a Merkle path. An error may be detected if the Merkel root does not match or if a calculated element is a right-hand element and the provided element is a left-hand element or a copy. The transaction is verified as the last in the block if at every level except the root the calculated element is a right-hand element (as in a full Merkle tree). Alternatively, in case of a partial (non-full) tree, if it is determined that the left-hand and right-hand elements are a copy. Thus, validating the presence and index of a transaction within a block and whether the transaction is the last transaction in the block. Methods and devices for performing a Merkle proof using the index may include an extended validity check within the Merkle proof process. The extended validity check may enable validation of transaction counts for a block and/or a proof of index validity.
