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.

Abstract: A system for positioning a cartridge is disclosed. The system has a drive rod with a body having a first axis and a groove formed in the body. The groove has a first portion that is not perpendicular to the first axis and a second portion that is perpendicular to the first axis. The system also includes a collar that coupled to the drive rod. The collar has an element configured to engage the groove. Rotation of the drive rod with respect to the collar while the element is engaged in the first portion of the thread causes the collar to move with respect to the first axis. Rotation of the drive rod with respect to the collar while the element is engaged with the second portion of the thread causes the collar to remain stationary with respect to the first axis.

Abstract: A streamlined buyback solution may pre-calculate user data and pre-assess a user inventory, and then may present a buyback offer to a user based on user activity. A user trust assessment may determine the trust score for the user. The buyback assessment may identify items in the user inventory and determine assessed values and opportunity criteria for the items based on data from cost analysis and/or data from user behavior analysis. The opportunity criteria may be based on a model that is trained to analyze user patterns using a learning model. Based on the trust score, assessed values, and opportunity criteria, the user may be presented with a streamlined buyback offer allowing the user to apply the buyback offer value to discount a primary purchase order in a seamless transaction.

Abstract: Personal audio systems and methods are disclosed. A personal audio system includes a voice activity detector to determine whether or not an ambient audio stream contains voice activity, a pitch estimator to determine a frequency of a fundamental component of an annoyance noise contained in the ambient audio stream, and a filter bank to attenuate the fundamental component and at least one harmonic component of the annoyance noise to generate a personal audio stream. The filter bank implements a first filter function when the ambient audio stream does not contain voice activity, or a second filter function when the ambient audio stream contains voice activity.
