Methods and devices to design and fabricate surfaces on contact lenses and on corneal tissue that correct the eye's optical aberrations

Methods and devices are described that are needed to design and fabricate modified surfaces on contact lenses or on corneal tissue that correct the eye's optical aberrations beyond defocus and astigmatism. The invention provides the means for: 1) measuring the eye's optical aberrations either with or without a contact lens in place on the cornea, 2) performing a mathematical analysis on the eye's optical aberrations in order to design a modified surface shape for the original contact lens or cornea that will correct the optical aberrations, 3) fabricating the aberration-correcting surface on a contact lens by diamond point turning, three dimensional contour cutting, laser ablation, thermal molding, photolithography, thin film deposition, or surface chemistry alteration, and 4) fabricating the aberration-correcting surface on a cornea by laser ablation.

Operator control device

An operator control device for controlling systems in a motor vehicle by inputs by a user includes a touch-sensitive operator control panel on which it is possible to represent two surface shapes which may be changed into one another alternately, with the first surface shape being structured so as to be capable of being sensed in a tactile fashion so that it may be used to select zones on the operator control panel in order to select menu items. The individual selectable zones may be configured differently in shape, extent and their position on the operator control panel, and the second surface shape is smoothed in comparison with the first shape so that hand-written and graphic inputs are possible with it.

Contour triangulation system and method

A method and apparatus for reconstructing a surface shape of an object having contour lines, includes assigning points to each contour line. A first triangulation scheme is performed with respect to respective points on two adjacently-positioned contour lines, to determine a first surface shape for a portion of the object corresponding to the two contour lines. The first surface shape is checked to determine if the first surface shape is in error. If the first surface shape is not in error, the first surface shape is outputted for the portion of the object as determined by the first triangulation scheme, as a reconstructed surface shape for that portion of the object. If the first surface shape is in error, a second triangulation scheme is performed with respect to the respective points on the two contour lines, to determine a second surface shape for that portion of the object, and the second surface shape is outputted for that portion of the object as determined by the second triangulation scheme, as a reconstructed surface shape.

Helical antenna

A helical antenna has a helix supported by a helix support. The helix support includes at least one piece of flexible sheet having its two surfaces covered with a layer antistatic material. The flexible sheet is curlable into a revolution surface configuration to form a revolution surface-shaped support section for at least partially supporting a portion of the helix component there around. A grounding mechanism electrically grounds the external sheet surface to the helix and the two sheet surfaces to one another when in the revolution surface configuration while a locking mechanism locks the flexible sheet in the revolution surface configuration. The combination of the helix and the flexible support renders the antenna structurally relatively rigid in all directions.

Manufacturable geometries for thermal management of complex three-dimensional shapes

Uniform cooling of complex surface shapes in injection mold tooling can be accomplished with cooling channels that conform to the shapes of the mold cavity or mold cone. By conventional methods this can be very difficult to accomplish. By applying methods of material deposition or material sintering, which include but are not limited to, laser metal deposition, where material is deposited on a layer by layer basis, certain cooling or heating passages could be integrated into the manufactured component that follow the contours and profiles of the mold's complex surfaces. These passages would act as internal heat sinks with a much higher surface area for heat transfer than traditional drilled and plugged straight passages. These geometries could also be incorporated into complex geometries such as, but not limited to, turbine blades where the cooling passages can follow the contour of the outer shape, provide a more uniform or controlled heat transfer from the component. Multiple loops of cooling or heating channels could be designed and manufactured into solid objects for small-scale heat exchanger technologies.

Random microlens array for optical beam shaping and homogenization

Microlens arrays are defined with microlens elements that differ from each other in accordance with a probability distribution for shaping an optical beam having a prescribed intensity profile within a desired far-field scatter pattern. The differences include random variations in a sag profile corresponding to a surface shape of the microlenses, a boundary profile corresponding to a boundary of the microlenses, and a spatial distribution corresponding to the relative position of the microlenses within the array. The sag profile variations can be used to homogenize an intensity profile of the optical beam. The boundary profile variations within an irregular spatial distribution can be used to apply the prescribed intensity profile of the optical beam within the desired scatter pattern.

In one aspect, a flying vehicle (e.g., an unmanned aerial vehicle (UAV)) is aligned onto electrical recharging contacts. The flying vehicles fuel level or battery charge can be replenished with minimal, if any, human intervention. Vehicle docking (e.g., landing), alignment, and replenishment can be performed automatically. A circular ring or shaped surface of a vehicle can engage with a conical sloping surface of a docking apparatus as a vehicle moves towards and / or into the docking apparatus. The conical sloping surface shape aligns the vehicle with recharge contacts or a refueling probe at the base of the docking apparatus.

Method and device for three-dimensional surface detection with a dynamic reference frame

ActiveUS20100303341A1Simple and robust acquisitionImage enhancementImage analysisData setSingle exposure
The surface shape of a three-dimensional object is acquired with an optical sensor. The sensor, which has a projection device and a camera, is configured to generate three-dimensional data from a single exposure, and the sensor is moved relative to the three-dimensional object, or vice versa. A pattern is projected onto the three-dimensional object and a sequence of overlapping images of the projected pattern is recorded with the camera. A sequence of 3D data sets is determined from the recorded images and a registration is effected between subsequently obtained 3D data sets. This enables the sensor to be moved freely about the object, or vice versa, without tracking their relative position, and to determine a surface shape of the three-dimensional object on the fly.
