A housing for an electrical connector is disclosed. The housing has a base member and at least one wall element produced from a more wear-resistant material than the base member and including a positive-locking element. The wall element is connected to the base member.

A switch cabinet includes a pair of opposing side panels. At least one side panel of the pair of side panels includes an opening defined therein. The switch cabinet also includes at least one component removal system coupled to the at least one side panel. The component removal system is selectively movable between a first position to prevent withdrawal of an electrical component through the opening and a second position to enable withdrawal of the electrical component through the opening.

A hierarchical approach is provided to integrate functions and components into the various systems and subsystems within a distribution network, including standardization of modular and scalable power electronics power blocks with embedded diagnostics and prognostics.

A plate having an upper surface and a lower surface, a center point, and an outer perimeter. It further includes a plurality of clips for temporarily securing the plate in an opening in a landscape box. Each of the plurality of clips comprises a limb, extending vertically downward, the limb having the form of a rectangular plate and being upper bound by an upper edge and lower bound by a lower edge, wherein the upper edge is attached to the lower surface of the plate. The limb further includes a foot extending horizontally sideways from the lower edge.

A host interface for a media device comprises a first and a second host audio terminal for receiving a first and a second analog audio signal, a first and a second connector audio terminal for connecting a first and a second pole of a four-pole connector, and a host control circuit. The host control circuit is adapted to detect whether a device requiring a supply signal over the four-pole connector is connected. If no such device is detected, the first and the second analog audio signal are passed to the first and the second connector audio terminal. If such a device is detected, the first connector audio terminal is connected to a supply terminal.

A service system for gas compartments with a gas treatment device for treating a gas present in at least one gas compartment, at least one sensor device for monitoring at least one gas property of the gas, at least one connection coupled to the gas treatment device and the at least one sensor device, which connection is intended for coupling to the gas compartment, at least one conveying device for conveying a gas from the gas compartment into the gas treatment device and from the gas treatment device at least indirectly back into the gas compartment, and at least one control unit which is connected at least to the sensor device and monitors and controls at least the conveying device and/or the gas treatment device.

A base assembly for the rack of a switchgear cabinet, comprising horizontal frame profiles which have the height h and which surround a base section of the rack, wherein at the height h, the frame profiles have a first horizontal mounting plane, is characterized in that, spaced from the first horizontal mounting plane, at least one additional mounting plane is provided, on or adjoining a fixed support which is formed at least sectionally on one or more of the frame profiles and projects into the base section.

A control method of microphone and an electronic apparatus are provided. In the control method, a switching operation is received. In response to receiving the switching operation, a sound-receiving state of a target program is detected. The sound-receiving state of the microphone is switched through an audio effect processing corresponding to the target program according to the detection result of the sound-receiving state, to switch the sound-receiving state of the target program from one of an activated state and a disabled state to the other. The switching operation is used for switching the sound-receiving state of the microphone. The sound-receiving state represents whether to receive sound through the microphone. The sound-receiving state includes the activated state and the disabled state. The target program is a currently running application. The audio effect processing is implemented by an audio engine between an application layer and a driver layer.

An audio cable with switchable transmission direction, includes an audio cable line. One end of the audio cable line is provided with a first interface for connecting with an audio device, and other end of the audio cable line is provided with a second interface for connecting with a terminal device. A switch module is arranged at a middle part of the audio cable line. The switch module is electrically connected with the first interface and the second interface. When the switch module is located at a first position, the audio cable line features a function of inputting audio signals from an audio device to a terminal device; when the switch module is located at a second position, the audio cable line features a function of outputting the audio signals from the terminal device to the audio device.
