Abstract: The present disclosure relates to a method and system for acquiring and processing large unlabeled dataset of images to train an embedding model using a self-supervision technique, which may then be used to generate image embeddings with reduced dimensions for any downstream task or model. The downstream model can be a simple model and can be trained efficiently using a small, labeled training dataset as the embedding model may distill important information from the images of the small, labeled training dataset. According to present disclosure, the downstream task or model may include predicting a material category or quantity of a target material of interest in an image that captures (part or all of) one or more objects on a feedstock or a waste stream. In some instances, the image may correspond to a hyperspectral image that is collected using a camera system.

Abstract: During a process of refractive index modification of an intraocular lens (IOL) using an ophthalmic laser system, optical position monitoring of the IOL is performed by a video camera system viewing the top surface of the IOL. Fiducials are incorporated into the IOL at manufacture, or created in-vivo with laser. The monitoring method employs a defined area of interest (AOI) to limit the number of pixels to be analyzed, to achieve adequately high acquisition speed. In one example, the AOI contains 5 camera scan line segments, each line segment having sufficient pixels to create a stable amplitude signature. Successive frames of the AOI are analyzed to detect movement of the fiducial and/or to determine whether the fiducial has been lost.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for designing a multimodal photonic component. In one aspect, a method includes defining a loss function within a simulation space including multiple voxels and encompassing features of the multimodal photonic component.

The initial structure is defined for one or more features, where at least some of the voxels corresponding to features have a dimension smaller than a smallest operative wavelength of the multimodal photonic component, and values for structural parameters for the features are determined so that a loss according to the loss function is within a threshold loss.

Abstract: The present invention enables a user to share his/her listening experience selectively with others without sharing headphones and without disturbing others who do not want to listen. In a preferred embodiment, a first listener can accomplish this by storing in a Portable Electronic Device or similar device a library of listening experiences, listening to one of the listening experiences, and while listening to that one listening experience streaming the one listening experience to at least one other Portable Electronic Device or similar device. A second listener at the other Portable Electronic Device can then listen to the same listening experience as the first listener at the same time. It is expected that the listening experiences will typically be songs or other music but the invention may be practiced with any type of audio content. The first listener may also create a playlist of the listening experiences in the library and make the playlist available to others.

Abstract: A counterbalance mechanism in an ophthalmic laser system balances the weight of the laser beam delivery head and provides small, precise and repeatable variations in the net load exerted by the laser head on the patient's eye over a defined distance of travel. The counterbalance mechanism includes a balance beam pivotably mounted on a support block, with the laser head and a counterweight mounted on its two ends. The counterweight is movable along the balance beam via a linear motion bearing. A mechanical link links the counterweight to the support block; the link has a predefined length and is pivotable around its respective connection points on the support block and the counterweight. When the balance beam pivots, the link causes the counterweight to move along the balance beam, thereby changing the mechanical advantage of the counterweight and varies the counterbalancing force to provide variations in the net load.

Abstract: A method implemented in an ophthalmic surgical laser system for forming a corneal flap in a patient's eye with improved bubble management. The flap includes a horizontal bed and a vertical or near vertical side cut around the periphery of the bed except for an uncut hinge area. The side cut has a bubble barrier layer that can prevent bubbles formed by the laser-tissue interaction from escaping into an interface between the corneal and the patient interface lens. In some embodiments, the bubble barrier layer is a thin uncut layer, located in the epithelium of the cornea, that separates the side cut into two portions. In other embodiments, the side cut does not reach the anterior corneal surface, leaving an uncut bubble barrier layer located with the epithelium. In other embodiments, an additional side cut portion is formed through the uncut bubble barrier layer as the last step.

Abstract: In some embodiments, a method for designing a photonic device is provided. A design optimization system receives an initial design for the photonic device. The initial design includes one or more inputs, one or more outputs, a number of subcomponent regions, and a number of waveguides for connecting the subcomponent regions. The design optimization system simulates each subcomponent region to determine simulated s-parameters of each subcomponent region. The design optimization system determines overall s-parameters for a simulated photonic device based on the simulated s-parameters of each subcomponent region and s-parameters of the waveguides. The design optimization system determines an overall gradient associated with the overall s-parameters. The design optimization system optimizes one or more subcomponent regions based on the overall gradient to create an updated design for the photonic device.

Abstract: A configurable port fitting for a container, such as a bioprocess bag, has a septa gasket groove and two opposing locking arms. The port fitting is mounted onto the container by (i) inserting one end of the port fitting into a port in the container such that a unitary septa gasket forms a seal between the port fitting and the container and (ii) rotating the port fitting to engage the locking arms with two opposing retention clips of the container. Some port fittings are fixed port fittings that provide a fixed opening into the container. Other port fittings are port sizers that receive a valve connector that enables flow control between closed and open positions. Port fittings of different sizes enable different flow rates. Some port fittings (and other connectors) have a threaded tube barb that receives a threaded tube retainer that secures tubing in place over the barb.

Abstract: A ophthalmic laser-assisted corneal lenticule extraction procedure that uses wavefront measurements to guide the formation of the corneal lenticule. The wavefront map measured from a free eye using a wavefront aberrometer is registered to the cornea of a docked eye based on comparisons of iris images and corneal markings. The docked-eye cornea-registered wavefront map is then corrected to be consistent with the Munnerlyn formula for the spherical power, and adjusted for any physician adjustments and/or myopia error due to a flat add in the lenticule, using Zernike polynomials. The corrected and adjusted wavefront map is then used to calculate the profiles of the bottom and top lenticule incisions in the applanated cornea, where higher-order components in the wavefront map are distributed to the bottom lenticule incision alone and lower-order components in the wavefront map are distributed to both the bottom and the top lenticule incision.
