Abstract: Embodiments of this application provide a middle frame, a battery cover, and an electronic device. The electronic device may include a mobile or fixed terminal with an edge frame or a housing, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a walkie-talkie, a netbook, a POS machine, a personal digital assistant (PDA), an event data recorder, a wearable device, a virtual reality device, a wireless USB flash drive, a Bluetooth speaker/headset, or a vehicle-mounted device. Two types of materials: ceramics and plastic, are used to form a middle frame and a battery cover, thereby reducing a weight of the electronic device. This resolves a problem that is of a relatively large weight of an existing electronic device and that is caused when a pure ceramic middle frame and a pure ceramic battery cover are used in the electronic device.

Abstract: Presented here is a system and method for creating easy-to-understand notifications of the vehicle state. The notification can be visual or can be auditory and can indicate to the user the vehicle state even when the user's attention is directed elsewhere. The indication can serve to attract the user's attention before more involved information is presented to the user, such as text, or the indication can serve to communicate to the user the vehicle state in an easy-to-understand way such as using color-coded displays or audio indications. The intensity of the indication can be adjusted based on the likelihood that indication will be perceived by the user by, for example, measuring ambient light and/or ambient noise. Reducing the intensity of the indication conserves energy of an energy source associated with the vehicle.

The one or more filter cartridges my include a second filter cartridge. The second filter cartridge may include a second outlet opening. The example method may include aligning the first outlet opening of the first filter cartridge with at least the first portion of the at least one air inlet of the blower device.

Abstract: Various embodiments described herein are directed to a face mask assembly configured with a drop-down feature and methods of using the same. In various embodiments, a face mask assembly comprises a face mask configured for dynamic engagement with a first strap of a strap assembly such that the face mask is configured for selective movement along a strap length of the first strap between a donned position and a drop-down position, the face mask comprising: a first strap pathway configured to receive at least a portion of the first strap and a strap engagement tongue positioned along the first strap pathway and comprising a plurality of strap engagement teeth protruding from of the interior tongue surface; wherein the face mask is configured to be selectively adjustable between a dynamic configuration and a locked configuration based on the arrangement of the first strap relative to the strap engagement tongue.

Abstract: Embodiments of this application provide a middle frame, a rear cover, and fabrication methods thereof, and an electronic device. The electronic device may include a mobile or fixed terminal with a frame or a housing, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a walkie-talkie, a netbook, a POS terminal, a personal digital assistant (PDA), an event data recorder, a wearable device, a virtual reality device, a wireless USB flash drive, a Bluetooth speaker/headset, or a vehicle-mounted device. Ceramics and fiber reinforced composite are used to form frames of a rear cover and a middle frame, to reduce thicknesses of a ceramic outer housing and a ceramic outer frame, thereby reducing a weight of the electronic device.

Abstract: A system for multi-chassis interconnection and a method for chassis connection are disclosed. The system includes at least three chassis; each chassis includes a first switch fabric unit (SFU) and a second SFU; the first SFU in the first chassis is connected to the first SFU in other chassis; and the second SFU in the second chassis is connected to the second SFU in other chassis. In the embodiments of the present invention, different SFUs in the chassis of the multi-chassis interconnection system are connected to different main chassis, thus overcoming the technical defect in the prior art that other chassis in the multi-chassis interconnection system are unable to exchange data when the main chassis is faulty. Therefore, in the embodiments of the present invention, other chassis in the multi-chassis interconnection system can still exchange data normally when the main chassis is faulty.
