Title: A system for monitoring occupancy and activity in a space
Inventor: KOSTRUN MARIJAN
IPC: G06K9/00
Filed: 2019-04-10
Abstract: Disclosed herein are embodiments of an occupancy monitoring system. The occupancy monitoring system includes a thermal sensor configured to monitor a gate (e.g., entry way) to a space. The thermal sensor includes a pixel array that generates a pixel value for each pixel in the pixel array, and the pixel value corresponds to a quantity of heat or thermal information detected by a pixel. The occupancy monitoring system acquires pixel values for the pixels of the pixel array. The occupancy monitoring system determines whether there is a change in occupancy of the space based on changes to a first region (or first pixel cluster) of the pixel array and a second region (or second pixel cluster) of the pixel array over time. The occupancy monitoring system may adjust lighting, temperature, and/or security systems for the space as the occupancy changes.

Title: Personalized hrtfs via optical capture
Inventor: JOYNER MCGREGOR STEELE
IPC: H04S3/00
Filed: 2019-07-25
Abstract: An apparatus and method of generating personalized HRTFs. The system is prepared by calculating a model for HRTFs described as the relationship between a finite example set of input data, namely anthropometric measures and demographic information for a set of individuals, and a corresponding set of output data, namely HRTFs numerically simulated using a high-resolution database of 3D scans of the same set of individuals. At the time of use, the system queries the user for their demographic information, and then from a series of images of the user, the system detects and measures various anthropometric characteristics. The system then applies the prepared model to the anthropometric and demographic data as part of generating a personalized HRTF. In this manner, the personalized HRTF can be generated with more convenience than by performing a high-resolution scan or an acoustic measurement of the user, and with less computational complexity than by numerically simulating their HRTF.
