  • Publication number: 20220415319
    Abstract: Implementations described herein relate to generating, locally at a client device, corresponding subset(s) of zero-prefix suggestions, for a user of the client device, and for suggestion state(s) associated with the client device, and subsequently causing the client device to utilize the corresponding subset(s) of zero-prefix suggestions. The suggestion state(s) and a superset of candidate zero-prefix suggestions can be processed, using machine learning model(s), to generate a corresponding score for each of the candidate zero-prefix suggestions and with respect to the suggestion state(s). Further, zero-prefix suggestions can be selected for inclusion in the corresponding subset(s) of zero-prefix suggestions, and for the suggestion state(s), based on the corresponding scores.

  • Publication number: 20220390184
    Abstract: A vapor chamber and a heat dissipation device with the vapor chamber are provided. The vapor chamber includes a first plate, a second plate, a first capillary strip, a first communication structure and a working medium. An accommodation space is defined by the first plate and the second plate collaboratively. The first capillary strip is installed in the accommodation space. The accommodation space is divided into a first region and a second region by the first capillary strip. The working medium is accommodated within the accommodation space. The working medium flows between the first region and the second region through the first communication structure. Since the working medium is guided to flow in the accommodation space by the first capillary strip and the first communication structure, the heat dissipating efficacy is enhanced.

  • Publication number: 20220358619
    Abstract: A system produces a dolly zoom effect by utilizing side view information. The system first captures a main image at a main location. The main image includes at least a foreground object of a given size and a background. The system calculates one or more side view locations based on a zoom-in factor to be applied to the background and an estimated size of the foreground object. The system then guides a user to capture one or more side view images at the one or more side view locations. The foreground object of the given size is superimposed onto a zoomed-in background. Then the side view information is used by the system to perform image inpainting.

  • Publication number: 20220349746
    Abstract: An optical detector module can be used to implement proximity sensing function by detecting ambient light outside of the optical detector module in accordance with a first detection threshold. An optical detector module can be further used to implement other active functions such as material detection (e.g., skin) or depth-sensing by emitting one or more optical signals (e.g., light pulses at a specific wavelength) and detecting the reflected optical signals relative to a second and/or third detection threshold. The disclosure provides technical solutions for actively monitoring detection threshold(s) of an optical detector module to achieve better power management. In some embodiments, such solutions are useful for photodetectors having a wide sensing bandwidth, such as a photodetector formed in germanium or a photodetector comprising an absorption region comprising germanium.
