20200059748 | AUGMENTED REALITY FOR DIRECTIONAL SOUND - Providing a user with an augmented sound experience include receiving an identification an object within an environment proximate a user; determining a location of the object within the environment; determining a current location of the user within the environment; and causing a speaker array to produce a sound based on the current location of the object and the current location of the user such that the sound appears, relative to the current location of the user, to originate from the current location of the object. | 2020-02-20 |
20200059749 | METHODS AND SYSTEMS FOR DETERMINING AND/OR USING AN AUDIO FILTER BASED ON HEAD-TRACKING DATA - Disclosed is a method for determining an audio filter. The method includes obtaining head-tracking data representing a head pose, also referred to as a head position, relative to a torso pose of an intended subject, and selecting a representation of a Head Related Transfer Function, HRTF, from a HRTF database, based on the head-tracking data and information representative of the position and/or direction of a sound source. The method also includes determining the audio filter based on the selected HRTF representation. | 2020-02-20 |
20200059750 | SOUND SPATIALIZATION METHOD - The present disclosure relates to a method and equipment for sound spatialization comprising applying the filtering of a sound signal with a transfer function which takes into account a determined profile through the acquisition of an impulse response of a reference room, characterized in that it includes a step of modifying said transfer function according to a signal representative of the amplification amount. | 2020-02-20 |
20200059751 | METHODS AND APPARATUS FOR TRACKING ELECTRONIC DEVICES - An electronics tracking device is useful for tracking use of electronic devices, such as durable medical equipment (DME), typically used at remote locations, such as a patient's home. The electronics tracking device can be securely attached to an electronic device and a power cord that supplies power to the electronic device can be connected to the tracking device. The tracking device can then be connected, with its own power cord, to power. Power to the electronic device flows through the electronics tracking device. The electronics tracking device includes a wireless communications circuit that permits the device to send a signal to a monitoring location, where the signal includes data regarding whether the electronics tracking device is plugged in and whether the DME is powered on or off. The monitoring location can use exceptions to notify a DME provider when the DME is not used for a certain period of time. | 2020-02-20 |
20200059752 | System and Method for Improving Telematics Location Information and Reliability of E911 Calls - System, devices and methods are provided to automatically initiate an enhanced 911 (E911) call from a telematics control unit (TCU) (e.g., a TCU deployed with cellular modem or mobile phone in a vehicle) to an answering point (e.g. public safety answering point or access point (PSAP)). A wireless carrier (e.g., mobile service center (MSC)) employs a positioning determining entity (PDE) and algorithm to improve caller location determination using information provided by the TCU (e.g., GPS and dead reckoning information generated at the vehicle) and network location information when needed, and provides PDE estimated location of the caller to the PSAP (e.g., using a data channel and optionally a voice channel) to mitigate errors in TCU location data and reduce potentially conflicting location information provided to PSAPs from TCUs and wireless carriers or other phone service providers. | 2020-02-20 |
