The invention proposes a lighting device for a motor vehicle. Such a device includes one or more electronic circuits incorporating electronic components sensitive to an electrostatic discharge. Thanks to the features of the invention, the components are protected by encouraging the controlled flow to ground of any electrostatic discharges. All portions of one or more electronic circuits can therefore be protected by preventing random electrostatic discharges liable to destroy or to degrade sensitive electronic components.

Over-voltage protection systems and methods are disclosed. In one aspect, a biasing circuit is added to a pre-existing clamp required by the Universal Serial Bus (USB) Type-C specification at a configuration control (CC) pin. The biasing circuit turns the pre-existing clamp into an adjustable clamp that dynamically adjusts to over-voltage conditions. In an exemplary aspect, the biasing circuit may include a biasing field effect transistor (FET) and a pair of switches that selectively couple the pre-existing clamp and the biasing FET to fixed voltages such that the CC pin is maintained at an acceptable voltage. In another exemplary aspect, the biasing circuit may omit the biasing FET and rely on two switches that selectively couple the pre-existing clamp to fixed voltages such that the CC pin is maintained at an acceptable voltage.

A coil component capable of matching characteristic impedance (Zo) includes an insulating layer in which coil conductors are embedded; a first magnetic member disposed to be in contact with one surface of the insulating layer; and a second magnetic member having permeability lower than that of the first magnetic member and disposed to be in contact with the other surface of the insulating layer. An interval L1 between the second magnetic member and the coil conductors depends on an intended impedance value.

An electronic device may have a display and other electrical components that are sensitive to electrostatic charge. A button may pass through an opening in a layer of the display. A metal trim may surround the button. The housing may have an opening with a clear lens surrounded by a metal trim. To prevent damage from electrostatic discharge, an electrostatic discharge path may be formed in the device that includes a metal trim surrounding a component such as a button member or camera lens, metal traces on the inner surface of a display layer or a housing, a grounded metal housing structure, and a spring or other conductive structure that couples the metal traces to the grounded metal housing structure. Displays may be provided with electrostatic discharge paths that route electrostatic charge to grounded metal housing structures.

An electronic device includes an exterior portion of a conductive material, a circuit portion including circuit elements, and a protection circuit portion connected between the exterior portion and the circuit portion. The protection circuit portion includes a switching unit to intercept leakage current that flows from the circuit portion and leaks to the exterior portion, and a conversion unit to reduce a voltage level of an electrostatic component that flows through the exterior portion and to transfer the electrostatic component to the switching unit.

An ESD (ElectroStatic Discharge) protection component has: first and second discharge electrodes arranged so as to be opposed to each other through a gap; and a discharge inducing portion kept in contact with the first and second discharge electrodes and configured to connect the first and second discharge electrodes to each other. The discharge inducing portion has metal particles, a ceramic material containing glass, and a dielectric material having a dielectric constant higher than that of the ceramic material. A content of the dielectric material is in the range of 7.5 to 40% by volume, with respect to a total volume of the ceramic material and the dielectric material.

A display device includes a display panel; a back cover having a front side facing the display panel and a rear side opposite the front side, the back cover having a back cover cavity open on at least the rear side of the back cover; a nut coupled to the back cover, a lower body of the nut disposed in the back cover cavity, a stopper of the nut protruding along the rear side of the back cover and in contact with the rear side of the back cover, the nut having a fastening cavity; and a screw comprising an engaging portion and a head, the engaging portion held in the fastening cavity of the nut, the screw securing a printed circuit board between the head of the screw and the back cover.

A discharge device and a display panel preparation system based thereon are disclosed. The discharge device includes a conductive contact terminal electrically connected with an electrostatic discharge contactor of a substrate to be processed; and a voltage controller electrically connected to the contact terminal for adjusting a voltage on the contact terminal. The discharge device is able to eliminate (e.g., neutralize) the static electricity on the substrate to be processed.

According to various embodiments of the present disclosure, a camera device comprises a camera housing where a camera assembly is mounted; a decoration part covering the camera housing; and a fixing part provided along a periphery of the camera housing and fixing the decoration part, wherein the fixing part includes a path part along which static electricity introduced through the decoration part moves a discharge module mounted adjacent to the camera housing. Various other embodiments are possible as well.

An assembly is provided which includes a package and a printed circuit board. The package includes a housing bounding a region and an acoustic sensor within the region. The housing includes a base with a first hole. The sensor is configured to generate signals indicative of sound received by the sensor through the first hole. The printed circuit board is in mechanical communication with the base and includes a second hole aligned with the first hole such that sound received by the second hole propagates through the first hole to the sensor. The printed circuit board further includes an electrically conductive layer, at least a portion of which extends across the second hole and is configured to allow the sound to propagate through the second hole and to at least partially shield the region containing the sensor from electromagnetic interference.
