Abstract: A modular audio system which includes an acoustic module (104) configured to be removably engaged with a head-worn peripheral device. In some examples, the head-worn peripheral device is a pair of eyeglass frames and the acoustic module is configured to removably secure to a socket arranged on the inside face of the temples of the eyeglasses. The acoustic module may be configured to magnetically engage with the peripheral device such that, in a resting, coupled position, respective components of magnetic retention force are provided in at least two axial directions that are orthogonal to each other i.e., a first component of magnetic retention force is provided in a first (horizontal) axial direction and a second component of magnetic retention force is provided in a second (vertical) axial direction.

Abstract: Aspects describe a raised feature to help a user remove an in-ear audio output device from a case. Aspects describe a device comprising an earbud housing shaped to fit in a concha of an ear of a wearer of the device, and a body coupled to the earbud housing, the body extending away from an ear canal of the wearer and oriented outside of the ear when the device is worn, the body comprising a top cap comprising a flat external portion and a raised feature proximate to a concha cymba of the wearer and external to the ear when the device is worn.

Certain implementations include an audio device with a sealing member for providing a substantially water resistant seal. Certain additional implementations include an audio device with an internal heat sink for transferring heat away from device components such as a control module.

Abstract: An audio device with charging contacts on a printed circuit board (PCB) is described herein. In some implementations, the charging contacts are on a surface of the PCB that is a bottom external surface of the audio device, thereby eliminating the need for a custom connector block. Thus, cost and height savings can be realized. In some implementations, the charging contacts are designed to enable 360 degree docking ability with a charging dock. This can be achieved using one or more ring-shaped charging contacts that make physical contact with spring-loaded pins on the charging dock in any relative axial alignment. In some implementations, the audio device includes a mating feature configured to mate with a mating feature of the charging dock to help ensure a proper charging connection is made and to help physically center the audio device relative to the charging dock.

Abstract: Various implementations include audio devices and components of such devices. In some particular cases, a keypad for an audio device includes a base having an array of circumferentially separated slots. The keypad further includes a set of light emitting diodes (LEDs) each located in a corresponding one of the slots in the base, and a cover over the base and the set of LEDs. The cover has a set of lenses each corresponding with one of the LEDs and forming a space over the corresponding LED to diffuse light from the corresponding LED, such that when powered, the set of LEDs is configured to provide a continuous ring of light around the keypad.

Abstract: A method for processing an image of a microfluidic device. The method includes receiving a first image of a microfluidic device. The first image corresponds to a first state. Additionally, the method includes receiving a second image of the microfluidic device. The second image corresponds to a second state. Moreover, the method includes transforming the first image and the second image into a third coordinate space. Also, the method includes obtaining a third image based on at least information associated with the transformed first image and the transformed second image, and processing the third image to obtain information associated with the first state and the second state.

Abstract: A liftable freight container (1) is provided with a support frame (F) mounted on hinges (H) on a support strut (S) to define a triangular structure, a stay (T) being pivotally mounted at the apex and having its distal end releasable connected (20) to the base (2) of the container. This strengthens the container for lifting at its corner fittings (8, 9). The stay can be folded back against the frame to allow the latter to be swung outwardly for loading/unloading.

Abstract: A microturbine power generating system includes a reservoir that is pressurized with compressor air during system operation. The pressurized air in the reservoir is used to purge combustor fuel nozzles of residue after combustion in the combustor has ceased.

Abstract: A microturbine power generating system includes an electrical generator and a turbine having a fixed inlet nozzle geometry. Maximum thermodynamic efficiency of the microturbine power generating system is achieved by maintaining the turbine inlet at or near maximum temperature. When power demanded of the system is constant, power is supplied by the electrical generator. When an increase in power is demanded, at least a portion of the entire demand is supplied by a battery or other energy storage device until the electrical generator can satisfy the increased power demand. Conversely, when a decrease in power is demanded, the load on the generator is temporarily increased (effectively putting a brake on the generator and turbine) and such load is absorbed by the battery or other energy storage device.

Abstract: A microturbine power generation system includes an electrical generator, a turbine and a compressor intermediate the generator and the turbine. The turbine, compressor and electrical generator are secured together by a tieshaft. The tieshaft is prestressed such that faces of the turbine, electrical generator and compressor maintain contact during high-speed, high-temperature operation of the system.

Abstract: An auxiliary system includes a plurality of devices that are driven by ac motors. A plurality of independently controllable isolators couple phase windings of the ac motors directly to phase windings of the electric generator. When an isolator connects the phase windings of its corresponding ac motor to the windings of the electric generator, the ac motor is operated directly on a high frequency unconverted output of the electric generator. Motor speed is determined by the number of poles on the ac motor relative to the number of poles of the electric generator. Pole-switching allows the speed of the motor to be varied.

Abstract: A gravity latch for a swinging gates such as a corral gate or a gate on a box stall. The latch has a barrel and keeper mounted on the gate and a gate post. They are both rectangular metal tubes and inclined downwardly from the barrel to the gate at an angle of 45.degree.. The barrel and keeper have parallel rows of fastener openings through them to enable the fastening of the barrel and keeper to gates and posts of various types, including wooden and steel corral gates. A bolt for the latch is in the form of a source metal tube that slides along the barrel and the keeper. In the latched condition, it is completely enclosed within the barrel and keeper to prevent opening of the gate by an animal.
