UNIVERSAL HAND CONTROLLER (17656707)
Abstract
Techniques of controlling electronic devices using gestures use a wearable device on a user which translates, via a model, user movements into signals that both identify an electronic device to be controlled and a specific action to take with regard to that electronic device. The wearable device includes an inertial measurement unit (IMU) sensor and a photoplethysmography (PPG) sensor and measure six degrees of freedom (6DOF). The model is a convolutional neural network (CNN) that takes x, y, and z-acceleration signals generated by the IMU and PPG and places each acceleration component generated from each sensor in a separate channel. The CNN takes the input from each channel and generates a respective, separate model for each channel.

METHODS AND APPARATUS FOR BYPASSING HOLDS (18199711)
Abstract
Automated monitoring of a voice communication session, when the session is in an on hold status, to determine when the session is no longer in the on hold status. When it is determined that the session is no longer in the on hold status, user interface output is rendered that is perceptible to a calling user that initiated the session, and that indicates that the on hold status of the session has ceased. In some implementations, an audio stream of the session can be monitored to determine, based on processing of the audio stream, a candidate end of the on hold status. In response, a response solicitation signal is injected into an outgoing portion of the audio. The audio stream can be further monitored for a response (if any) to the response solicitation signal. The response (if any) can be processed to determine whether the end of the on hold status is an actual end of the on hold status.

The technology generally relates to spatial audio communication between devices. For example, a first device and a second device may be connected via a communication link. The first device may capture audio signals in an environment through two or more microphones. The first device may encode the captured audio with direction information. The first device may transmit the encoded audio via the communication link to the second device. The second device may decode the encoded audio to be output by one or more speakers of the second device. The second device may output the decoded audio to recreate positions of the captured audio signals.

Spatial Audio Guided By Ultra Wideband User Localization (17702472)
Abstract
The present disclosure provides a mechanism to synchronously drive distributed speakers around a user based on localization outputs of ultra wideband (UWB) communication chips already existing in devices. Distances may be determined between a user device, such as a phone or wearable, and a plurality of distributed speakers or other devices. Based on an intersection point of such distances, the user's location can be identified. Such location can be used to modify how audio is played on each of the plurality of distributed speakers.

Searching For Local Establishments Based On Content Presented (18127037)
Abstract
The present disclosure provides for searching and identifying establishments based on content to be presented at the establishment. For example, businesses can add attributes to a business profile, the attributes indicating sports, leagues, teams, matches, etc. that the business will display. The attributes may be searchable by a user, such as through a search engine application, a maps application, or other application. In this regard, the user can quickly identify a business in a selected region that will be playing what the user wants to watch.
