Compensating for binaural loudspeaker directivity
The directivity of a loudspeaker describes how sound produced by the speaker varies with angle and frequency. Low-frequency sound tends to be relatively omnidirectional, while high-frequency sound tends to be more strongly directional. Because the two ears of a listener are in different spatial positions, the direction-dependent performance of the speakers can produce unwanted differences in volume or spectral content between the two ears. For example, high-frequency sounds may appear to be muffled in one ear, compared to the other. A multi-speaker sound system can employ binaural directivity compensation, which can compensate for directional variations in performance of each speaker, and can reduce or eliminate the difference in volume or spectral content between the left and right ears of a listener. The binaural directivity compensation can optionally be included with spatial audio processing, such as crosstalk cancellation, or can optionally be included with loudspeaker equalization. |

Superconductivity device comprising a phononic crystal
The invention is directed to a device and method to engineer the superconducting transition width by suppressing the phonon populations responsible for the Cooper-pair decoherence below the superconducting transition temperature via phononic bandgap engineering. The device uses phononic crystals to engineer a phononic frequency gap that suppresses the decohering thermal phonon population just below the Cooper-frequency, and thus the normal conduction electron population.

Flip chip LED with side reflectors and phosphor
An array of light emitting devices is mounted on a support surface with the transparent growth substrate (e.g., sapphire) facing up. A photoresist layer is then deposited over the top surface of the growth substrate, followed by depositing a reflective material over the top and side surfaces of the light emitting devices to encapsulate the light emitting devices. The top surfaces of the light emitting devices are then ground down to remove the reflective material over the top surface of the photoresist. The photoresist is then dissolved to leave a cavity over the growth substrate having reflective walls. The cavity is then filled with a phosphor. The phosphor-converted light emitting devices are then singulated to form packaged light emitting devices. All side light is reflected back into the light emitting device by the reflective material and eventually exits the light emitting device toward the phosphor. The packaged light emitting devices, when energized, appear as a white dot with no side emission (e.g., no blue halo). |
