A microphone assembly comprises a substrate. An acoustic transducer is disposed on the substrate and configured to generate an electrical signal responsive to an acoustic signal. An integrated circuit is disposed on the substrate and electrically coupled to the acoustic transducer. An enclosure is disposed on the substrate, and comprises a main body, and a sidewall projecting axially from outer edges of the main body towards the substrate and contacting the substrate such that an internal volume is defined between the enclosure and the substrate. An insulating layer is insert molded on an inner surface of the enclosure, or over molded on an outer surface of the enclosure such that the insulating layer is not disposed on a portion of the sidewall proximate to the substrate.

The technology described herein is generally directed towards a gateway device (e.g., a cable modem or telecommunications modem) that is coupled to a base component. The base component couples to an interchangeable lid that is coupled to an electronic device. This forms a sealed housing for outdoor use, e.g., between a provider head end and the subscriber(s). A universal interface provides power or a network connection, or both, to the electronic device. The base component and/or the sealed housing protect the internal components against environmental effects. The base component and/or the sealed housing protect against external RF signals from entering, and internally generated RF signals from exiting.

A solid state circuit breaker assembly includes a transistor, a transient voltage suppression device, and a circuit board. The transistor and/or the transient voltage suppression device may be electrically connected to the circuit board. The solid state circuit breaker module may be configured to be connected to one or more non-scalable modules to regulate current. The solid state circuit breaker module may be configured to receive one or more scalable modules. The transistor and/or the transient voltage suppression device may be disposed on the circuit board in a substantially symmetrical configuration.

A system for providing electromagnetic interference (EMI) suppression for data processing devices includes a frame adapted to receive a data processing device of the data processing devices. The system further includes the data processing device that includes a payload module adapted to suppress EMI from an internal volume to an ambient environment by greater than 80 decibels. The data processing device further includes the internal volume adapted to house EMI emitting devices that generate EMI.

A data processing device includes an internal volume that is electromagnetic interference (EMI) isolated and a communication system, disposed in the internal volume, that: determines a first EMI state of at least one device of devices disposed in the internal volume; makes a determination that the first EMI state is an EMI emitting state; and disables communications by the communication system using a high-speed connection while allowing the communications using a low-speed connection.

Embodiments describe a wireless charging device including: a housing having an outer perimeter and a charging surface within the outer perimeter, the housing including a first wall and a second wall that define an interior cavity; and a transmitter coil arrangement disposed within the interior cavity and below the planar charging surface. The transmitter coil arrangement includes: a plurality of transmitter coils arranged in different layers, each transmitter coil having a first termination end, a second termination end, and a coil of wire that winds from an inner diameter to an outer diameter between the first and second termination ends; where the first termination end of each transmitter coil is disposed within the inner diameter of its respective coil of wire and the second termination end of each transmitter coil is disposed outside the outer diameter of its respective coil of wire.

A plurality of electronic circuit boards (2), on which electronic components are mounted, is inserted in parallel through an electronic circuit insertion port (11) of a casing body (1). A gap (3) is formed between front panels (22) of inserted and adjacent electronic circuit boards (2) inserted. A bridge body (5) constituting conduction means electrically conducts a first conductive side portion (22a) of a front panel (22) in one electronic circuit board (2) of adjacent electronic circuit boards (2) and a second conductive side portion (22b) of a front panel (22) in another electronic circuit board (2) that faces the first conductive side portion (22a) via a gap (3).
