Abstract: The invention provides an improved rotationally stabilized contact lens design and method of designing such a lens which minimizes stabilization time of the lens while maximizing the lens on-eye comfort. The lens and the method of designing the lens utilizes and combines non-circularity and thickness differential aspects resulting in equivalent or minimized stabilization time, ease of insertion and manufacturability as well as maximum comfort that is improved over that of what either aspect can achieve independently.

Abstract: Determining a barrier effect of a coating for a medium includes: providing a substrate having the coating on its surface, the substrate undergoing a volume change on contact with the medium; conditioning the substrate with the coating; removing the coating from a first part of the surface, leaving the coating on a second part, the first part having an extent in a first direction delimited by the coating remaining on the second; determining a height profile of the coating on the second part and the first part on a path in the first direction; exposing the remaining coating and the first part to the medium; determining a second height profile of the coating on the second part and the first part on the path in the first direction and/or determining a difference in height profile on the second and first part with respect to the height profile determined beforehand.
Abstract: A foldable roll-over protection structure is provided for use on a vehicle movable in a generally fore-and-aft direction. The foldable roll-over protection structure includes a frame comprising a base section and an upper section. The base section is connectable to the vehicle. The upper section is swingable relative to the base section between a forward position in which the upper section projects forwardly from the base section, a rearward position in which the upper section projects rearwardly from the base section, and an upright position positioned between the forward and rearward positions. A hinge assembly swingably interconnects the sections of the frame. The hinge assembly is configured to releasably secure the upper section in each of the positions of the upper section.
Abstract: An optical light emission system for a motor vehicle, the optical system comprising: a first light emission subsystem comprising a first set of light sources, and a second light emission subsystem comprising a second set of light sources and a light guide able to diffuse the light from said light sources of the second set of light sources outside the optical system. The light guide is arranged facing the first set of light sources such that the first set of light sources substantially radiates through the light guide outside the optical system.

Abstract: The present disclosure generally relates to processing visual data of a road surface that includes a vertical deviation with a lateral slope. In some embodiments, a system determines a path expected to be traversed by at least one wheel of the vehicle on a road surface. In some embodiments, a system determines, using at least two images captured by one or more cameras, a height of the road surface for at least one point along the path to be traversed by the wheel. In some embodiments, a system computes an indication of a lateral slope of the road surface at the at least one point along the path. In some embodiments, a system outputs, on a vehicle interface bus, an indication of the height of the point and an indication of the lateral slope at the at least one point along the path.

Abstract: Imaging system and method, the system including a main detection unit, an auxiliary detection unit, an image processor, and a controller. The main detection unit includes a light source that emits light pulses and a gated image sensor that receives reflections of the light pulses reflected from a selected depth of field in the environment and converts the reflections into a reflection-based image. The auxiliary detection unit includes a thermal sensor that detects infrared radiation emitted from the environment and generates an emission-based image. The image processor processes and detects at least one region of interest in the acquired reflection-based image and/or acquired emission-based image. The controller adaptively controls at least one detection characteristic of a detection unit based on information obtained from the other detection unit. The image processor detects at least one object of interest in the acquired reflection-based image and/or acquired emission-based image.

Abstract: Methods and systems for vector combining power amplification are disclosed herein. In one embodiment, a plurality of signals are individually amplified, then summed to form a desired time-varying complex envelope signal. Phase and/or frequency characteristics of one or more of the signals are controlled to provide the desired phase, frequency, and/or amplitude characteristics of the desired time-varying complex envelope signal. In another embodiment, a time-varying complex envelope signal is decomposed into a plurality of constant envelope constituent signals.
