Abstract: An audio device includes a first speaker and a second speaker. A front surface of a membrane of the second speaker faces a rear surface of a membrane of the first speaker. The membrane of the first speaker moves in an opposite direction than the membrane of the second speaker when the audio device outputs audio content. This configuration maintains isobaric pressure for a back volume shared between the first speaker and the second speaker, reducing vibration of the audio device when outputting audio content.

Abstract: A speaker assembly presents audio content to an ear canal of a user. A speaker of the speaker assembly generates positive and negative acoustic pressure waves. A first vent assembly of the speaker assembly ports the positive acoustic pressure waves to an entrance of the ear canal of the user, whereas a second vent assembly ports the negative acoustic pressure waves to an area behind a pinna of the user. The first and second vent assembly are configured to provide improved audio content playback to the user.

Abstract: A protective case for a wireless tracking device featuring a flexible annular bezel. One embodiment features an annular bezel having a conforming interior channel which engages the sides of the tracking device, and an upper opening, which leaves a portion of the upper side of the tracking device exposed. Certain embodiments feature a bezel that permits the tracking device to be inserted into the protective case relatively easily, while other embodiments feature a cover which engages with a base, making removal of the tracking device impractical without damaging the case itself. One embodiment may be used with shoelaces and features a flat elastomeric surface to which graphic designs may be applied.

Abstract: An acoustic sensor includes port architecture designed to mitigate wind noise. The acoustic sensor includes a primary waveguide having two ports open to a local area surrounding the acoustic sensor. One opening of a secondary waveguide is coupled to portion of the primary waveguide, with another opening of the secondary waveguide coupled to a microphone. The secondary waveguide has a smaller cross-section than the primary waveguide. Hence, airflow is directed from a port of the primary waveguide to the other port of the primary waveguide and back into the local area, bypassing the microphone.

Abstract: A method of controlling a temperature of water delivered by a water heating system, includes providing communication device which is adapted to receive a communication from at least one mobile device, the communication device being located so as to determine when the at least one mobile device is within a predefined zone in which is located a pre-selected water access point. In response to a determination that the at least one mobile device is within the predefined zone, enabling a user selecting a temperature setting of the where the water heating system. The selection is wirelessly communicated to a receiver which is in communication with the water heating system.

Abstract: An ear-plug assembly presents audio content to an ear canal of a user. The audio content may be based in part on sound in a local area surrounding the user. The ear-plug assembly detects, via one or more acoustic sensors, sound in the area around the user. The sound waves travel through an aperture in a body of the ear-plug assembly and are propagated to a waveguide to the one or more acoustic sensors. The ear-plug assembly processes the detected sound data in a controller, which instructs a speaker assembly to present audio content based in part on the detected sound data. The detected sounds may be amplified, attenuated, filtered, and/or augmented when presented by the speaker assembly.

Abstract: A bumper (1) for a mobile device that includes a first layer (18) formed from an elastomeric first material and a second layer (2) formed from a second material different from the elastomeric first material. The first layer (18) is arranged on an outside of the bumper and the second layer (2) is arranged on an inside of the bumper so that the second layer (2) is between the mobile device and the first layer (18) when the mobile device is arranged in the bumper (1). The bumper (1) completely covers the mobile device, except for at least a portion of the front, at least a portion of the rear, and at least one speaker of the mobile device if present, when the mobile device is arranged in the bumper (1).

Abstract: A sliding breechblock for a cannon includes a translatable, removable insert assembly that contains electrical firing pin and data link modules. The removable insert assembly is translatable in a direction normal to the central longitudinal axis of the barrel thereby enabling removal of the insert assembly without removing the breechblock from the breech ring. Mating portions formed on the breechblock and on the insert assembly prevent displacement of the insert assembly with respect to the breechblock in the direction along the central longitudinal axis of the barrel.
