A card connector includes a transmission conductor assembly that includes a backup transmission conductor, a first signal transmission conductor, an inspection signal transmission conductor, a first grounding transmission conductor, a command reset transmission conductor, a first differential transmission conductor, a second differential transmission conductor, a second grounding transmission conductor, a third grounding transmission conductor, a fourth grounding transmission conductor, a first power transmission conductor, a second power transmission conductor, a third differential transmission conductor, a fourth differential transmission conductor, a second signal transmission conductor, a fifth grounding transmission conductor, a sixth grounding transmission conductor, a seventh grounding transmission conductor, a fifth differential transmission conductor, a sixth differential transmission conductor, and a write-protection transmission conductor, each of which has two ends respectively forming a spring section and soldering section. The soldering sections, being so arranged, achieve advantages of bettering high frequency performance, reducing capacitive effect, and suppressing electromagnetic radiation interference.

A RFID signal repeater system includes a RFID repeater circuit and a housing body. The repeater circuit has a first RFID antenna and a second RFID antenna being connected by an electrical path. A RFID signal captured at one of the antennas is repeated at the other antenna. The housing body includes a first housing portion housing the first antenna and supporting a RFID reader device, whereby the RFID device is in RFID communication with the first antenna when supported by the first housing portion. The body also includes a second housing portion mechanically connected to the first housing portion and configured to support the second antenna and a programmable RFID device, whereby the programmable RFID device is in RFID communication with the second antenna when supported by the second housing portion. The housing body can have various form factors. A power repeater enabling wireless charging can also be provided.

A memory card reader body includes proposed, on an internal face, a receiving recess to receive a memory card connector. The receiving recess has electrically conductive tracks forming a protective mesh for the memory card connector. The conductive tracks are such that they also extend on an external face of the memory card reader body through vias passing through the internal and external faces.

A card reading apparatus includes an insertion slot into which a card is inserted, a card reader configured to read information from the card inserted into the insertion slot, and a guide portion extending from the insertion slot and formed of a conductive material that removes static electricity.

Described is an invention that provides methods to identify key features from magnetic image captures of complex magnetic fields of randomly positioned and oriented magnetized particles in an object. The key features are described in a compact form to generate a unique identifier that services as a “fingerprint” of a chip.

An electric apparatus includes a substrate having a ground pattern on a top surface of the substrate; a conductive housing on the ground pattern and having an insertion space; a conductive connector disposed between the ground pattern and the conductive housing and connected to the ground pattern and the conductive housing, wherein the conductive housing is fixed to the substrate via the conductive connector; and a conductive cover coupled to the conductive housing, wherein the conductive cover is configured to move from a first position, at which the conductive cover externally opens the insertion space, to a second position, at which the conductive cover closes the insertion space.

This document describes techniques and apparatuses, including card connector assemblies with integrated component shielding for electronic devices. The card connector assembly includes frame, a riser, and a shielded contact block. The frame includes a card holder that receives a universal integrated circuit card (UICC). The riser supports the card holder spaced apart from the PCB. The shielded contact block configured for surface mounting to a printed circuit board (PCB) that includes an electronic component. The shielded contact block includes a recess that receives a portion of the electronic component therein, an interconnect that connects at least one pin on the UICC with at least one contact, and a component shield located in the recess. The component shield defines a shielded area configured to attenuate electromagnetic waves generated by the electronic component.

Embodiments of the present disclosure relate to a stabilizing apparatus for a plug-in card, a chassis including the stabilizing apparatus and associated manufacturing method. The stabilizing apparatus comprises a fixed part adapted for attaching the stabilizing apparatus to a chassis for supporting the plug-in card and a contact part electrically coupled to a ground terminal of the chassis and movable towards the plug-in card supported on the chassis along a first positive direction perpendicular to an extended plane of the plug-in card, so as to contact the plug-in card.

A cover of a connector has axis portions and first and second cover contact points. A housing has axis receiving portions and first through third contact portions. The axis portions are received by the axis receiving portions, and the cover is attached to the housing to be placed at any one of an open position, a closed position and a locked position. The first contact portions are exposed in the axis receiving portions. When the cover is placed at the locked position, the axis portions are face the first contact portions from beneath, and the second cover contact points are face the second contact portions from beneath. When the cover is placed at the closed position, the first cover contact points do not touch the third contact portions. When the cover is placed at the locked position, the first cover contact points touch the third contact portions.
