  • Publication number: 20190276139
    Abstract: A control system (200) using fixed point computation avoids overflow conditions by limiting the internal quantities ensuring that contributing calculations from various parts of the control loop never add up to an overflow. Various parts of a control loop e.g. proportional terms can be prioritised over other parts, e.g. integral and differential terms and ensuring that the overall total resulting when the separate terms are summed together never exceeds the maximum or minimum imposed limits. Variable limit calculator circuits (211,219) revise the limits according to the output of the higher priority control path(s). The revised limits cascade down through each contributor, eventually allowing the lowest priority control path the smallest authority. The control system may be applied to control of a drive motor (111) for an aircraft inceptor (103).

  • Patent number: 10412199
    Abstract: A tactical network comprises a plurality of assets, at least some of the assets grouped into sub-groups. The assets within each subgroup communicate with each other using a communication protocol. The sub-groups include a first subgroup in which the assets all communicate with each using a first communication protocol and a second sub-group in which the assets all communicate with each other using a second communication protocol which is incompatible with the first communication protocol. Each subgroup is associated with a federated server. The federated server is configured to receive data from the assets, to assess the data to identify significant changes, to convert the significant changes in the data into a common format, compatible with all federated servers in the tactical network, and to transmit, in the common format, to the federated server of another of the subgroups, the significant changes.

  • Patent number: 10409059
    Abstract: The present invention provides a projection display, for displaying an image to a viewer. An image-providing light source device is arranged to inject an input pupil of multi-spectral image bearing light into a waveguide assembly. The waveguide assembly comprises first and second diffraction regions arranged respectively for expanding the input pupil in first and second generally orthogonal dimensions and outputting an exit pupil expanded in the first and second dimensions from the waveguide assembly. The diffractive regions of the waveguide assembly are matched to cause zero or substantially zero net chromatic aberration. A combiner is arranged to direct the exit pupil towards the viewer for viewing an image and to transmit light from a real world scene through the combiner so that the image overlays the light from the real world scene.

A systems engineering model (100) comprising, as inputs, parametric model inputs (10, 18) is then determined. System model outputs (28) are dependent on the system model inputs. Groups consisting of some of the system model inputs are formed and an optimization process is performed, for each group, to determine inputs that optimize the system model outputs (28). A set of inputs that optimize the system model outputs (28) provides a design for the system.
