Patent number: 11915707Abstract: A speech recognition platform configured to receive an audio signal that includes speech from a user and perform automatic speech recognition (ASR) on the audio signal to identify ASR results. The platform may identify: (i) a domain of a voice command within the speech based on the ASR results and based on context information associated with the speech or the user, and (ii) an intent of the voice command. In response to identifying the intent, the platform may perform multiple actions corresponding to this intent. The platform may select a target action to perform, and may engage in a back-and-forth dialog to obtain information for completing the target action. The action may include streaming audio to the device, setting a reminder for the user, purchasing an item on behalf of the user, making a reservation for the user or launching an application for the user.Type: GrantFiled: June 14, 2021Date of Patent: February 27, 2024Assignee: Amazon Technologies, Inc.Inventors: Jeff Bradley Beal, Kevin Robert Charter, Ajay Gopalakrishnan, Sumedha Arvind Kshirsagar, Nishant Kumar

Patent number: 9176384Abstract: The invention comprises methods for the photolithographic patterning of features in a photo-curable polymer composition coated onto a plastic substrate. In one embodiment of this invention, the plastic substrate is coated with a reflective film such as a metallic barrier. In another embodiment, the plastic substrate is coated or co-extruded with a polymer barrier layer containing an additive that absorbs the photo-curing radiation. In yet another embodiment the plastic substrate contains an intrinsic additive that absorbs the photo-curing radiation. Combinations of these embodiments are also within the scope of this invention. The methods of the present invention may be advantageously applied to the fabrication of optical waveguides comprising a photo-curable polymer supported on a plastic substrate, but are applicable to the fabrication of any device or object comprising a photo-curable polymer supported on a plastic substrate.Type: GrantFiled: December 9, 2011Date of Patent: November 3, 2015Assignee: ZETT RESEARCH AND DEVELOPMENT LLC—RPO SERIESInventors: Robert Charters, Dax Kukulj

Publication number: 20060188198Abstract: This invention relates to optical splitters, particularly to optical splitters for use in optical touch screens. The present invention provides an optical splitter for distributing light substantially equally from a multimode input waveguide to an array of output waveguides, via a slab region. The distribution of output waveguide widths is chosen to complement the intensity distribution in the slab region, which may or may not be substantially uniform. The invention also provides an optical splitter for distributing light substantially equally from an optical source to a plurality of waveguides, wherein said optical source directs a beam of light into a slab region. The distribution of waveguide widths is chosen to complement the intensity distribution in the slab region, which may or may not be substantially uniform. When used to distribute optical power in optical touch screens, the splitters of the present invention may be used in series and/or in parallel.Type: ApplicationFiled: December 9, 2005Publication date: August 24, 2006Applicant: RPO Pty LimitedInventors: Robert Charters, Benjamin Cornish

Publication number: 20060088244Abstract: A planar lenses for integrated optics applications, in particular for use in optical touch screen sensors are disclosed. The disclosed planar lenses include a slab waveguide and an optical waveguide, preferably formed in unitary fashion, wherein the slab waveguide has a curved end face to focus light into or out of the optical waveguide, and wherein at least one additional lens is included within the slab waveguide. In one aspect of this disclosure, the additional lens is a diverging lens. In a second aspect the additional lens is a converging lens. The additional lens may match the acceptance angle of the optical waveguide to the curved end face of the slab waveguide. Alternatively, it may improve the tolerance of the planar lens to design or assembly errors and/or temperature variations. Preferably, the planar lenses are composed of a photo-patternable polymer, and the additional lenses are composed of air.Type: ApplicationFiled: October 25, 2005Publication date: April 27, 2006Applicant: RPO Pty LimitedInventors: Dax Kukulj, Benjamin Cornish, Robert Charters, Graham Atkins, Barry Luther-Davies
