A computer-implemented method of generating one or more designs for a vehicle, using a vehicle modelling application arranged to generate a three-dimensional model of a vehicle from a vehicle model definition, the vehicle model definition defining a set of values for geometric properties of the vehicle. A set of vehicle model definitions is generated, each vehicle model definition satisfying a set of geometric constraints. The set of vehicle model definitions is then filtered by generating the three-dimensional model of a vehicle from a vehicle model definition using the vehicle modelling application, determining whether the three-dimensional model satisfies a first set of physical constraints, and if the three-dimensional model does not satisfy the set of physical constraints, removing the vehicle model definition from the set of vehicle model definitions.

Image frames are downscaled in the short-range pipeline, generating image windows and applying a trained convolutional neural network (CNN). Full resolution and non-redundant image chips are created. Detection region of interest (ROI) proposal lists are generated and analyzed with the CNN, producing frame detection lists with detected targets.

Abstract
A controller applies iterative ray tracing and root finding to determine an orientation difference Δθd of Risley Prism Assembly (RPA) prism elements required to provide a desired light refraction angle γd. In each iteration, a linear approximation is applied between lower and upper angle difference limits to determine an approximate value Δθa, and ray tracing is applied to determine a corresponding refraction angle γa. Depending on whether γa is greater than or less than γd, the upper or lower angle difference limit is reset to Δθa, and the process continues until convergence. Ray tracing also determines an angular rotation ϕa of a refracted beam about the rotation axis at Δθd, and the orientations of the prism elements are adjusted to provide a desired pointing direction γd, ϕd according to Δθd, ϕd, and ϕa. Prism element imperfections are accommodated in the ray tracing.

Abstract
A method is disclosed of efficiently synchronizing time bases of multi-netting network nodes. A first node transmits a synchronizing request on a subnet associated with the highest time quality in its source table, then simultaneously monitors that subnet and up to three additional subnets associated with lower time qualities in its source table. If the first node does not receive a response, it transmits the request on the subnet associated with the next highest time quality in its source table. A second node simultaneously monitors the subnet associated with its time quality and a plurality of subnets associate with consecutively higher time qualities. Upon receiving the synchronization request, it responds on the subnet associated with its time quality. The disclosed method is fully compatible with networks that include single-netting nodes, and can be implemented by a JTRS node exchanging RTT messages on a Link 16 network.

Techniques are provided for design verification of a bit spreading memory. A methodology implementing the techniques according to an embodiment includes using a bit spreading geometry file to convert a logical address of the memory to a physical address. The geometry file defines a scheme by which bits of a data word stored at the logical address are spread over multiple RAMs. The method also includes writing data bits of a test data word to the physical address, causing a design simulator to simulate a read from the logical address, and comparing the result to the test data word for verification. The method further includes causing the design simulator to simulate a write of the test data word to the logical address, reading data bits from the physical address, arranging the bits into a retrieved data word, and comparing the test data word to the retrieved data word for verification.
