Arcing exhaust gas removal for circuit breakers
A pole assembly housing for a miniature circuit breaker is structured to lessen pressure and temperature increases within the housing increase due to arcing gas. The housing includes an exhaust compartment, which includes an arc chamber where the separable contacts of the circuit breaker are located and an exhaust channel with a first end and a second end. The channel's first end is in fluid communication with the arc chamber and the second end is a vent opening in fluid communication with the environment external to the housing. The channel has a diverging shape such that the first end is the narrowest portion, and the channel widens between the first end and the vent opening. Multiple ribs are formed on the sidewall in the arcing chamber, and more ribs are formed on the walls surrounding the exhaust channel cool arcing gas and reduce pressure of the arcing gas.

Relay with pressure relief assembly for the contact chamber
A relay of the present disclosure includes an insulation cover (21), a first yoke plate (22), a contact assembly (3), a driving assembly (4) and a pressure relief valve assembly (5). The first yoke plate (22) connects with the insulation cover (21) and encloses a contact chamber (27) with the insulation cover (21). The first yoke plate (22) is provided with a pressure relief hole (221). The driving assembly (4) connects with the movable contact piece (32) and drives the movable contact piece (32) move. The pressure relief valve assembly (5) is on the first yoke plate (22) and configured to close the pressure relief hole (221) when a gas pressure in the contact chamber (27) is less than a threshold and configured to be broken to open the pressure relief hole (221) when the gas pressure in the contact chamber (27) is greater than or equal to the threshold.

Construction and protection of components in negative pressure wound therapy systems
Embodiments of negative pressure wound therapy systems and methods are disclosed. In one embodiment, an apparatus includes a housing, a negative pressure source, a canister, an antenna, and one or more controllers. The negative pressure source can provide negative pressure via a fluid flow path to a wound dressing. The canister can be positioned in the fluid flow path and collect fluid removed from the wound dressing. The antenna can be supported by the housing and wirelessly communicate with an electronic device. The antenna can be oriented in the housing to face downward toward the ground when the negative pressure source is providing negative pressure. The one or more controllers can activate and deactivate the negative pressure source and transmit first data to the electronic device using the antenna or receive second data from the electronic device using the antenna.

Capsule-shaped push button for speaker
A push button comprising: - an actuating member; - a flexible, generally flat base with a first hole and a rib extending from one face of the base around the first hole; - an elastic membrane having one end connected to one end of the actuating member and a second end connected to the first face of the base between the first hole and the rib; the push button being arranged such that, when pressure is applied to one end of the actuating member, the membrane deforms and the actuating member moves translationally along its axis towards the base, and such that when the pressure is released, the actuating member returns to its initial position. (Figure from the summary: Fig. 2)

Flexible hinge and removable attachment
Flexible hinge and removable attachment techniques are described. In one or more implementations, a flexible hinge is configured to communicatively and physically couple an input device to a computing device and may implement functionality such as a support layer and minimum bend radius. The input device may also include functionality to promote a secure physical connection between the input device and the computing device. One example of this includes use of one or more protrusions that are configured to be removed from respective cavities of the computing device along a particular axis but mechanically bind along other axes. Other techniques include use of a laminate structure to form a connection portion of the input device.
