Abstract: A first context update indicative of a present state associated with an application is received. A first contextual situation, among a plurality of contextual situations associated with a plurality of conditions, that corresponds to the first context update is identified. Identifying the first contextual situation includes implementing a decision tree to minimize a number of the plurality of conditions to be evaluated, identifying the first contextual situation using the decision tree, and determining one or more actions to be performed corresponding with the first contextual situation.

Abstract: Spatial audio may be generated by a speaker array that is switched according to rows and/or columns to reduce its cost and complexity. The speaker array may include a row of speakers that are each coupled to a different column channel. The rows of speakers can receive portions of the spatial audio on a row-by-row basis as each row is activated to couple the speakers in a row to their respective column. This switched approach reduces a number of required audio sources. The audio sources may generate PWM signals for each column using an approach that is similar to that found in Class-D amplification or sigma-delta Modulation. Analog signals may be recovered from the PWM signals using a low-pass filter positioned before each speaker in the array.

Abstract: A computing system can be configured for low-photon-count visual object classification. The computing system can include a photon detection system including one or more cells. Each of the one or more cells can include one or more photon detectors. Each of the one or more photon detectors can be configured to output photon signatures in response to a photon being incident on the one or more photon detectors. The computing system can include one or more processors and one or more memory devices storing computer-readable data. The data can include a low-photon-count classification model and one or more instructions that, when implemented, cause the one or more processors to perform operations for low-photon-count visual object recognition. The operations can include obtaining a photon signature from a photon detection system. The operations can include providing the photon signature to a low-photon-count classification model. The operations can include determining, by the low-photon-count classification model, a classification of a visual object disposed in view of the photon detection system based at least in part on the photon signature. The operations can include providing the classification as output of the low-photon-count classification model.

Abstract: A system and method includes receiving a first context update for an application. The method determines whether one or more of multiple rules has been satisfied in view of the first context update. The multiple rules include a multiple conditions and are associated with multiple contextual situations. The determining includes minimizing a number of the multiple conditions to be evaluated to determine whether a particular rule of the multiple rules has been satisfied. The method responsive to determining a first rule of the multiple rules has been satisfied, identifies a first contextual situation of the multiple contextual situations that is associated with the first rule. The method also determines at least one action that is associated with the first contextual situation.
