A power module structure includes a first metal layer, a second metal layer, a third metal layer and a fourth metal layer, wherein the fourth metal layer is connected to the second metal layer via a connecting bridge; at least one first switch including a first end connected to the third metal layer and a second end connected to the second metal layer; and at least one second switch including a third end connected to the fourth metal layer and a fourth end connected to the first metal layer; wherein the projection of the first metal layer and the projection of the third metal layer are overlapped to form a first overlapping area; wherein the direction of the current flowing through the first metal layer is opposite to the direction of the current flowing through the third metal layer.

A vehicle includes a cockpit module skin, a cross-bar and a vehicle tracking unit. The cockpit module skin separates a passenger compartment into a first area and a second area. The cross-bar is supported to a vehicle body component in the first area. The vehicle tracking unit has an electric tracking module and a mounting bracket supporting the electric tracking module to the cross-bar.

A display apparatus that is easily installed and assembled and a tiled display apparatus including the same are provided. The display apparatus comprises a display panel, and a support member supporting the display panel, and a power transfer member rotatably disposed on a first side of the support member.

A detonator module provides for the use of a wide range of different addressable switches for use in perforating guns. The detonator module permits pre-assembly of a desired addressable switch and conforms the electrical connectivity to a particular perforating gun. In this manner, nearly any addressable switch can be used from any manufacturer despite having different sizes or wiring layouts. The pre-assembled detonator module can be safely shipped due to a safety shunt that can be removed on site prior to installation into a perforating gun. In one sense, the detonator module permits conformance of multiple different types of addressable switches to a particular type or model of perforating gun, permitting flexible choice of addressable switch for a particular project.

An antenna device includes one or more zeroth-order resonant antennas and a metal body. Each of the zeroth-order resonant antennas includes a ground plate configured to provide a ground potential, an opposing conductor arranged at a predetermined distance from the ground plate in a plate thickness direction of the ground plate, a power supply line electrically connected to the opposing conductor, and a short-circuit portion electrically connecting the opposing conductor and the ground plate. The metal body is configured to limit a propagation direction of a radio wave transmitted from or received by the one or more zeroth-order resonant antennas and has an opening.

Described, herein, is an installation apparatus and method which may permit the safe and rapid mounting of an electrical device (e.g., a Wi-Fi access point or a surveillance camera) onto an elevated support surface (e.g., a wall, a post, or a ceiling). Accordingly, the installation apparatus may include a housing, a mount, and an elongated handle. During use, the mount may be configured to be affixed to the elevated support surface. Additionally, the elongated handle may be configured to selectively couple to the housing enabling a user to lift the housing to the mount on the elevated support surface. Subsequent to the user lifting the housing to the mount, the housing may be configured to selectively couple to the housing, securing the housing to the mount.

This disclosure provides a resource tapping method, a resource tapping apparatus and an electronic device, and relates to the field of computer technology, in particular to the technical field of artificial intelligence, such as deep learning and machine learning. A specific implementation is as follows: obtaining operation data in M resource dimensions of a target cabinet, the M resource dimensions including a power resource, where M is a positive integer; determining a target power over-allocation value of the target cabinet based on the operation data, the target power over-allocation value being used for indicating an allowable power increment on the basis of a power rating of the target cabinet; and determining, based on the target power over-allocation value, a first quantity of additional servers deployable in the target cabinet.

The technical field to which the invention pertains is securing objects from unauthorized use by children at home. ChargerSafe is a child-proofing apparatus to be used by parents to limit children-s screen time. ChargerSafe is a vented metal box with a combination, biometric, or digital lock and round openings with protective grommets in the sides that allow the user to thread charging cables from external electrical outlets to the inside where electronic devices (phones, tablets, chromebooks) are placed, plugged in, and charged with the door locked. Removable dividers are added inside to prevent devices from stacking. The principal use of the invention is locking devices up as a solution to the problem of screen time management at home. ChargerSafe combines the functions of securely storing electronic devices to prevent unauthorized use by children, while charging these devices at the same time.

The present disclosure discloses a mounting seat for an electronic device and an electronic apparatus. The mounting seat mounting seat for an electronic device, comprising a seat body and at least one wire limiting structure, a mounting region for mounting a wire weld portion of the electronic device is on the seat body, the wire limiting structure is on the seat body near the mounting region, and a limiting passage is on the mounting seat, wherein the limiting passage is at one of the following positions: a position between the wire limiting structure and the seat body; and a position on the wire limiting structure.

A duct assembly for covering electrical connections between electrical equipment enclosures having a gap therebetween. The duct assembly includes a first frame configured to be mounted to one of the enclosures, where the first frame includes a flange mounted to the enclosure and a flange to which a gasket is secured that extends all of the way around the first frame. The duct assembly also includes a second frame configured to be mounted to the other enclosure, where the second frame includes a flange mounted to the enclosure and a flange to which a gasket is secured that extends all of the way around the second frame. The duct assembly further includes a duct that compresses and is coupled only to the gaskets that enclose each end of the gap.
