Abstract: Methods and devices are provided for processing sound signals, localizing sound signals corresponding to one or more sound sources, and rendering, on a wearable display device, an acoustic visualization corresponding to localized sound sources. A wearable visualization device may include two or more microphones for detecting sounds from one or more sound sources, and display devices for displaying the acoustic visualizations, optionally in a stereographic manner. A sound source may be located by processing the sound signals recorded by the microphones to localize sound signals corresponding to a given sound source, and processing the localized sound signals to identify the location of the sound source. The acoustic visualization may be a frequency-domain visualization, and may involve a mapping of frequency to color. The acoustic visualization devices and methods provided herein may assist in training the human brain to comprehend sound visualization signals as sound signal itself.

According to one embodiment disclosed herein, the pad edges of a metallization pattern extend across a plurality of crystallographic planes in the laser substrate. In this manner, cracks initiated at any given stress concentration would need to propagate across many crystallographic planes in the substrate to reach a significant size. Additional embodiments of the present disclosure relate to the respective geometries and orientations of adjacent pairs of contact pads. Still further embodiments are disclosed and claimed.

Abstract: In accordance with one embodiment of the present disclosure, a method of evaluating the operating characteristics of a Distributed Bragg Reflector (DBR) laser diode is provided. According to the method, a diagnostic electrical current is injected into the wavelength tuning section of the DBR laser to generate amplified spontaneous emission of light in the wavelength tuning section. Light emitted from the wavelength tuning section is absorbed by the gain section and photo current generated by the light absorbed in the gain section is measured. The photo current measured in the gain section can be correlated with an evaluation of the operating characteristics of the DBR laser diode. For example, the measured photo current can be correlated with a substandard operating characteristic when it departs from a given photo current metric by more than an acceptable amount. Additional embodiments are disclosed and claimed.
