Abstract: A method includes generating light pulses by an illumination source toward an object; collecting the light pulses reflected from the object by an image sensor; generating a first signal-time plot of a sensor signal by the image sensor; generating a second signal-time plot of an index signal, wherein the second signal-time plot of the index signal comprises pulsed signals corresponding to the light pulses, respectively; collecting data from selected time periods of the first signal-time plot of the sensor signal, wherein the selected time periods of the first signal-time plot of the sensor signal are the same as time periods of the light pulses in the second signal-time plot of the index signal; and generating a third signal-time plot of an output signal based on the collected data.

Abstract: One or more systems and/or methods for filtering user profiles based upon sensitive topics are provided. A set of candidate topics labeled with sensitivity labels corresponding to whether candidate topics are sensitive topics or non-sensitive topics are generated. The sensitivity labels are applied to an unknown entity space of entities to label the entities with the sensitivity labels to create a set of labeled topics labeled as either the sensitive topics or the non-sensitive topics. The set of labeled topics and metadata for the set of labeled topics are stored within a central sensitivity data store. The set of labeled topics and metadata within the central sensitivity data store are used to filter sensitive topics from user profiles of users.

Abstract: A direct-time-of-flight (dTOF) detecting device is provided. The dTOF detecting device includes a single-photon avalanche diode (SPAD) sensor and a processor. The SPAD sensor is configured to receive a reflective light reflected from an object and output an original data based on the reflective light. The processor is coupled to the SPAD sensor and configured to process the original data to generate depth data and intensity data. The depth data includes depth information of the object and the intensity data includes a two-dimensional image of the object.

Abstract: An adaptive controller used in a photoplethysmography sensing system, comprises a plurality of hardware circuits which are configured to: receive a photoplethysmography signal (hereinafter, “PPG signal”) processed; determine whether the PPG signal processed satisfies with a requirement; output the PPG signal processed if the PPG signal processed satisfies with a requirement; and adjust a gain of an amplifier for amplifying the PPG signal and/or a driving signal of a light source if the PPG signal processed does not satisfy with a requirement.
