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: An apparatus may include a housing adapted for at least partial insertion into a concha bowl of a human ear, at least one speaker residing in or on the housing, a control system residing in or on the housing and a positioning element attached to the housing. The control system may be configured for controlling the speaker and configured for radio frequency (RF) communication. The positioning element may be configured to fit at least partially inside a concha of the human ear and may be configured to retain the housing at least partially within the concha bowl. The positioning element may include one or more wires Control System configured for communication with the control system. The one or more wires may be configured for at receiving and/or transmitting RF radiation. In some examples, the positioning element may be, or may include, a concha lock. The positioning element may include a loop antenna.

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.

Abstract: An input device for an electronic system includes a force sensor having conductive interdigitated traces on a bottom substrate and a flexible substrate spaced apart from the bottom substrate. The flexible substrate has a resistive layer deposited on a bottom side facing the interdigitated traces. A snap dome is positioned over a portion of the force sensor flexible substrate. A flexible keymat membrane is positioned over the force sensor and the snap dome. The keymat membrane bottom surface faces the force sensor flexible substrate. The keymat membrane bottom surface has a protruding region surrounding the snap dome and spaced above the force sensor flexible substrate. A center keycap on the keymat membrane top surface is positioned over the snap dome. A surrounding keycap on the keymat membrane encloses the center keycap and is positioned over the keymat membrane protruding region.

Abstract: A method and system for pairing a remote control transmitter and receiver includes associating an identification (ID) code with the transmitter. The transmitter includes a light generator for generating a light signal in order to perform a primary function which is visually detectable by a human operator. The light generator may be a laser pointer or a status indicator LED. The light generator is modulated to encode the identification code onto the light signal while the light generator is performing the primary function. The receiver includes a light signal detector such as an LED for receiving the light signal from the light generator. The receiver associates itself with the ID code contained in the light signal in order to pair the receiver with the transmitter. By being paired with the transmitter, the receiver acts upon transmitted command signals received from the transmitter.
