Abstract: Methods, systems, and apparatus for performing convolutional computations using an optical system. In some aspects computations for a neural network are performed in a digital domain using electronic circuitry, the neural network including a convolutional layer. Input data for the convolutional layer of the neural network is obtained, and a convolution or correlation computation on the input data in an analog domain using an optical correlator module is performed to generate an optical correlator module output. Based on the optical correlator module output, data is processed through additional layers of the neural network in the digital domain using the electronic circuitry.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for changing a distributed mode loudspeaker's fundamental frequency. One of the systems may include a light emitting diode display that includes an array of pixels, each pixel including, for each color of multiple colors, a directional light emitter and a wide-angle light emitter, a first combination of all the directional light emitters configured to generate a first display image viewable within a first viewing angle, and a second combination of all the wide-angle light emitters configured to generate a second display image concurrently with the generation of the first display image that is viewable within a second viewing angle. The first display image is a different image than the second display image and the first viewing angle is a narrower viewing angle than, and included within, the second viewing angle.

Abstract: A method that includes: providing a substrate including a layer of a crystalline material having a first surface; and exposing the first surface to an environment under conditions sufficient to cause epitaxial growth of a layer of a deposition material on the first surface, wherein exposing the first surface to the environment includes illuminating the substrate with light at a first wavelength while causing the epitaxial growth of the layer of the deposition material. The first surface includes one or more discrete growth sites at which an epitaxial growth rate of the quantum confined nanostructure material is larger than areas of the first surface away from the growth sites by an amount sufficient so that the deposition material forms a quantum confined nanostructure at each of the one or more discrete growth sites.

Abstract: An example method may include receiving, from a client computing device, an indication of a target drop-off spot for an object within a first virtual model of a first region of a delivery destination. A second virtual model of a second region of the delivery destination may be determined based on sensor data received from one or more sensors on a delivery vehicle. A mapping may be determined between physical features represented in the first virtual model and physical features represented in the second virtual model to determine an overlapping region between the first and second virtual models. A position of the target drop-off spot within the second virtual model may be determined based on the overlapping region. Based on the position of the target drop-off spot within the second virtual model, the delivery vehicle may be navigated to the target drop-off spot to drop off the object.

Abstract: An example system includes a disk that is rotatable and has a plurality of ferromagnetic elements disposed in a radial array on a surface of the disk; and at least one electro-permanent magnet (EPM) mounted adjacent to the disk such that a gap separates the disk from the EPM. Applying an electric pulse to the at least one EPM changes a magnetic state thereof, thereby generating an external magnetic field that traverses the gap between the disk and the EPM and interacts with a ferromagnetic element of the plurality of ferromagnetic elements, and causing a rotational speed of the disk to change as the disk rotates.
