Abstract: An apparatus includes a first modulator configured to modulate a radio frequency (RF) input signal onto a first optical signal and a second modulator configured to modulate a local oscillator (LO) signal onto a second optical signal. The apparatus also includes a photonic integrated circuit having an optical demodulator configured to generate, using the modulated optical signals, I and Q signals representing a demodulated version of the RF input signal. The optical demodulator may include an optical filter bank having multiple optical filters, where different optical filters are configured to pass different frequencies or frequency ranges. The optical filters may include at least one narrowband optical filter and/or one or more tunable optical filters. The narrowband optical filter(s) may be configured to isolate global navigation satellite system-related signals. The tunable optical filter(s) may be configured to isolate signals over a frequency range of about 900 MHz to about 12 GHz.

Abstract: A method and system for sizing an earpiece include situating a calibration device proximate a user's ear. The user holds an image capture device so as to aim the image capture device at the user's ear. The user then touches and holds a random area of the touch screen display and releases the touch screen display to activate the image capture device and capture an image of the user's ear and the calibration device. The captured image is then analyzed and an earpiece size is determined based on the analysis of the image.

Abstract: An ear measurement system and method include obtaining an image of an ear and an associated a calibration device, and analyzing the image to determine the size of desired portions of the ear. Such sizing is then used, for example, for fitting an earbud or earbud adapter.

Abstract: A system and method for providing earpieces for a user includes an inventory of standard earpieces having a plurality of different parameters, and a device for making a non-contact measurement of the user's ear, such as a camera or scanner. An ear-piece is selected from the inventory based on the non-contact measurement of the user's ear.
