A system includes a first printed circuit board (PCB), a temperature sensor, a switching circuit provided on the first PCB, and a controller. The temperature sensor is configured to measure temperature of at least an area of the first PCB. The controller is configured to trigger the switching circuit to turn off power to the first PCB, based at least in part on the temperature sensor detecting a temperature above a temperature threshold. The system is able to disrupt power much faster than conventional methods of power protection which may have a blind spot to certain areas of the first PCB, since these methods rely on power disruption when a maximum power is sensed.

An electrical control device including at least one power module which further includes at least one controlled power switch, at least one control card attached to the power module, and electrical connection which connect the control card to the control module. The electrical connection includes at least one pin which is electrically connected and extends from the power module, or, respectively, the control card, and at least one receptacle which is electrically connected and mounted on the control card, or, respectively, the power module, the pin being inserted, at least partially, into the receptacle. The pin and the receptacle is designed to provide an electrical connection between them whilst allowing the pin to be removed from the receptacle.

A display device includes a display part including a display panel in which a plurality of pixels is defined, a roller fastened with the display part and configured to wind or unwind the display part, a roller support unit configured to support the roller at both sides of the roller, and a first grounding unit including a body accommodated inside the roller so as to be movable and a contact portion connected to an outer surface of the body and brought into contact with the roller support unit as the body moves, thus maintaining and enhancing continuity of grounding and maximizing the effect of improving EMI.

A modular die cast enclosure comprising a top section with a top mid-plane and a bottom section with a bottom mid-plane and an internal bottom cover. The bottom section having one or more of a first type of connectors. The top section having one or more of a second type of connectors on. The internal bottom cover having one or more of a third type of connectors. Wherein said first type of connectors couple with said second type of connectors when the top section is placed on the bottom section and allow to electrically connect said top and bottom sections via said third type of connectors.

A display device includes: a display module having a first non-foldable area, a foldable area, and a second non-foldable area, which are arranged in a first direction in a unfolded state; and a first support layer disposed under the display module and having a lattice pattern including a plurality of first holes overlapping the foldable area, wherein the first holes are arranged in the first direction and a second direction intersecting the first direction, and wherein: each of the first holes has a first width in the second direction and a second width in the first direction, the first width is in a range from about 2,000 μm to about 9,000 μm, and the second width is in a range from about 100 μm to about 250 μm.

An electronic module, in particular for a hand-held power tool, includes at least one electronic unit, at least one contacting unit, and at least one cover unit. The at least one electronic unit is captively connected to the at least one cover unit. The at least one contacting unit includes at least one contact element that is configured to make contact with an electric energy source and/or to transfer electronic data. The at least one contacting unit also includes at least one fixing element that is configured to mechanically fix the cover unit, in particular to the tool. The at least one contacting element is mounted at least partially on the at least one fixing element.

The application concerns a cooling arrangement for a power tool and a power tool comprising the cooling arrangement. According to an aspect of the invention a cooling arrangement for a power tool comprises a housing of the power tool and electronics. The electronics include at least one circuit board and at least one electronic component. The electronics comprise at least one heat conductive area. The at least one heat conductive area is arranged to be heat conductively connected to the housing of the power tool.

The disclosure provides a back film structure, a method for manufacturing the back film structure, a display panel and a display device. The back film structure is divided into a bending region and a non-bending region. The back film structure includes a thin film layer and a barrier structure on a side of the thin film layer. An orthographic projection of the barrier structure on the thin film layer at least overlaps an orthographic projection of a boundary line between the bending region and the non-bending region on the thin film layer.

An electronic apparatus includes: a chassis formed of a conductive member and including an opening; a radiation source arranged in the chassis and radiating noise electric waves; and a conductor formed of a conductive member and arranged on a same side of the radiation source as the opening with at least a part of the conductor overlapping the opening in a plan view of the opening. The conductor has one end electrically connected to the chassis and the other end as an electrically open end.
