Flexible or curved display for MRI bore
A display system suitable for use inside an MRI system bore to display images to a patient undergoing an MRI procedure. The display system includes a curved display structure fitted inside the MRI bore, and having a width and length sufficient to present images to the patient inside the tunnel. First and second EMI shielding layers sandwich the curved display structure. A display electronics module is electrically connected to the curved display structure to provide video drive signals to the curved display structure. A housing for the display electronics module is configured to provide shielding to prevent EM signals from within the housing to affect MRI image processing.
Flexible laminate for shielding electromagnetic radiation
A flexible laminate for shielding against electromagnetic radiation includes: a) at least one metal foil; and b) a sheet-like substrate made of a fiber material, film material, or foam material. The laminate includes a plurality of objects formed by incisions into a base area of the laminate. Each object of the plurality of objects is made of two or more incisions having a common initial point. The two or more incisions, or each of two adjacent incisions of the two or more decisions, define an angle of 45° to 160°.
Conductive film and electronic device
A conductive film includes a transparent supporting layer and a conductive grid. The transparent supporting layer includes a first side face and a second side face arranged opposite to each other, and the first side face is provided with grooves. A conductive material is filled in the grooves to form the conductive grid interconnected, and the conductive grid includes a plurality of circle lattices. Since the conductive material is filled in the grooves to form the conductive grid and the conductive grid includes a plurality of circle lattices, the dot pattern presented is relatively soft, and the impact on vision caused by interference is reduced.
Optical window with integrated temperature sensing
Methods and apparatus for measuring and optionally adjusting the temperature profile of an optical window. In one example, an optical window with integrated temperature sensing functionality includes a first window layer of an optically transparent material, a second window layer of the optically transparent material, an electromagnetic interference shielding grid disposed between the first and second window layers and including a first electrically conductive structure and a second electrically conductive structure, and a thermally sensitive material disposed between the first and second electrically conductive structures, the thermally sensitive material having an electrical property that varies as a function of temperature.
ELECTROMAGNETIC WAVE SHIELDING FILM
An electromagnetic wave shielding film according to one embodiment of the present invention comprises a substrate and an electrode pattern, which is provided on one surface of the substrate and contains metal particles, wherein the metal particles comprise first particles having sizes within a first range and second particles having sizes within a second range that is smaller than the first range, respectively, the number of second particles is greater than the number of first particles, and at least one first particle is mixed in among the second particles.
OPTICAL WINDOW WITH EMBEDDED SCREEN
A method of embedding a screen in a substrate includes placing the screen on the substrate, and then melting part of the substrate, so that the screen becomes embedded in the substrate. The melting may involve heating at least part of the screen to melt part of the substrate, or directly heating the part of the substrate. The screen may be a screen of electrically-conductive material, and the heating may be Joule heating in which an electrical current is passed through the screen to heat the screen. Alternatively, the heating may involve microwave, conductive, or laser heating. The produced device of the substrate with an embedded screen may be an optical window with an embedded electromagnetic interference (EMI) screen, may be a touch screen or touch display, or may be a window with an embedded heating element, to give a few non-limiting examples.
FLEXIBLE ELECTROMAGNETIC SHIELDING THAT ATTENUATES ELECTROMAGNETIC INTERFERENCE

The electromagnetic shielding includes a layer of metal, such as aluminum foil, and a layer of thermoplastic polymer fabric (such as woven polyethylene fabric), where the electromagnetic shielding has several apertures that extend therethrough. The electromagnetic shielding is at least partially draped over electronic equipment that is to be shielded from EMI.
