Abstract: Embodiments of the present disclosure set forth techniques for mitigating ghost images in a heads-up display. A computer-implemented method includes generating content for display on a heads-up display system, inserting into the content a version of a display element, wherein the version of the display element comprises one or more visual characteristics configured to reduce a perceivability of a ghost image of the display element, and causing the content, including the version of the display element, to be displayed by the heads-up display system.

Abstract: In various embodiments, while a self-driving model operates a vehicle, a user monitoring subsystem acquires sensor data associated with a user of the vehicle and a vehicle observation subsystem acquires sensor data associated with the vehicle. The user monitoring subsystem computes values for a psychological metric based on the sensor data associated with the user. Based on the values for the psychological metric, a feedback application determines a description of the user over a first time period. The feedback application generates a dataset based on the description and the sensor data associated with the vehicle. Subsequently, a training application performs machine learning operation(s) on the self-driving model based on the dataset to generate a modified self-driving model. Advantageously, the dataset enables the training application to automatically modify the self-driving model to account for the impact different driving actions have on the user.

Abstract: In at least one embodiment, a system for generating a location map for a plurality of loudspeakers assemblies in a line array is provided. The system includes a first loudspeaker assembly that includes at least one controller. The at least one controller is programmed to receive a first unique identifier from a first adjacent loudspeaker assembly positioned in the line array. The first unique identifier is indicative of a location of the first adjacent loudspeaker assembly relative to the first loudspeaker assembly. The at least one controller is further programmed to generate a message including the first unique identifier which is indicative of a location the first adjacent loudspeaker assembly relative to the first loudspeaker assembly and to transmit the message to a server to generate the location map of the first loudspeaker assembly relative to the first adjacent loudspeaker assembly.

Abstract: A compression driver for an omnidirectional loudspeaker includes a motor assembly and an annular diaphragm disposed coaxially below and operably connected to the motor assembly. A phasing plug is mounted to the motor assembly and includes a top portion facing the diaphragm, a bottom portion extending downwardly from the top portion from a first end to a second end, and a plurality of apertures that extend therethrough. The bottom portion has an inner surface that defines a cavity and widens from the first end to the second end, the inner surface having a plurality of radial channels with a diagonal orientation acoustically connected to the apertures. A housing is mounted to the phasing plug and received within the cavity, the housing having an outer surface spaced from the inner surface of the bottom portion to form a waveguide arranged to radiate sound waves downwardly and outwardly with asymmetric vertical directivity.

Abstract: In at least one embodiment, a microphone assembly including a substrate, a printed circuit board (PCB), a micro-electro-mechanical systems (MEMS) transducer, a first lid, and a second lid is provided. The substrate defines a first port that extends completely therethrough. The PCB defines a sound opening that extends completely therethrough. The MEMS transducer is positioned on a first side of the substrate. The first lid defines a second port and covers the MEMS transducer and the first port. The first lid and the substrate define a front volume of air that surrounds the MEMS transducer. The second lid is positioned on the second side of the PCB. A cavity of the second lid, the sound opening of the PCB, the sound opening of the PCB, and the first port of the substrate define a back volume of air that is greater than the front volume of air.

Abstract: A headphone system includes a calibration microphone for performing a calibration routine with a user. The calibration microphone receives a stimulus signal emitted by the headphone system and generates a response signal indicating variations in the stimulus signal that arise due to physiological attributes of the user. Based on the stimulus signal and the response signal, the calibration engine generates response data. The calibration engine processes the response data based on a headphone transfer function (HPTF) associated with the headphone system in order to create an inverse filter that can reduce or remove acoustic variations caused by the headphone system. The calibration engine generates a personalized HRTF for the user based on the response data and the inverse filter. The personalized HRTF can be used to implement highly accurate 3D audio and is thereby well-suited for applications to immersive audio and audio-visual entertainment.

Abstract: A compression driver for an omnidirectional loudspeaker includes a motor assembly and a dome diaphragm disposed coaxially above and operably connected to the motor assembly, the diaphragm having a convex surface and a concave surface. The compression driver includes a phasing plug having a top portion and a bottom portion having a concave bottom surface disposed adjacent the convex surface of the diaphragm and defining a compression chamber therebetween. The phasing plug includes a plurality of conduits extending through the bottom portion for sound waves to travel and converging to form an annular exit, the top portion including a plurality of radially expanding channels acoustically connected to the annular exit. Actuation of the diaphragm by the motor assembly generates sound waves within the compression chamber which travel through the annular exit and the radially-expanding channels to create a generally horizontal 360° radiation pattern of the sound waves from the compression driver.
