A patterned article includes a unitary polymeric layer and a plurality of electrically conductive elements embedded at least partially in the unitary polymeric layer. Each electrically conductive element includes a conductive seed layer having a top major surface and an opposite bottom major surface in direct contact with the unitary polymeric layer, and includes a metallic body disposed on the top major surface of the conductive seed layer. The metallic body has a bottom major surface and at least one sidewall. The bottom major surface contacts the conductive seed layer. Each sidewall is in direct contact with the unitary polymeric layer and extends from the bottom major surface of the metallic body toward or to, but not past, a top major surface of the unitary polymeric layer. The conductive elements may be electrically isolated from one another. Processes for making the patterned article are described.

Patterned article including electrically conductive elements

A radar-optical fusion article for attachment to a substrate is described. The radar-optical fusion article includes a first retroreflective layer which is configured to retroreflect at least a portion of light having a wavelength in a range from about 400 nm to about 2500 nm. The radar-optical fusion article includes a second retroreflective layer disposed adjacent to the first retroreflective layer. The second retroreflective layer is configured to retroreflect at least a portion of an electromagnetic wave having a frequency in the range from about 0.5 GHz to about 100 GHz.

Various embodiments of a respirator that includes a harness, a mask body, and an exhalation valve are disclosed. The exhalation valve can include a valve seat and a flexible flap that is in engagement with the valve seat. The flexible flap can have one or more materials that can cause the flap to flash when moving from a closed position to an open position or vice versa. The flashing valve can make it easier for a user to ascertain whether the valve is operating properly.

The disclosed patterned wavelength-selective material and process for making the patterned wavelength-selective material uses patterned applied adhesive and a structurally weak wavelength-selective material that includes portions that contact the adhesive and break to remain in contact with the adhesive. In one embodiment, the wavelength-selective material comprises an array of sections with cuts at least partially through a wavelength-selective film at each section secured to the adhesive. In another embodiment, the wavelength-selective film comprises a transfer stack of layers.

Patterned wavelength-selective film

Wavelength-selective films are visibly apparent under the selective wavelength. Wavelength-selective films typically reflect off axis the selected wavelength and therefore can provide high-contrast against a background when applied in a pattern on a substrate. However, it is difficult to apply unique patterned embedded images from film. Disclosed is a cost-effective method and construction of a patterned wavelength-selective image to a substrate. In the disclosed wavelength-selective image, wavelength-selective film particles are applied to an adhesive pattern to create the wavelength-selective image.

An infrastructure article includes a signal receiver device configured to receive a wireless signal from a signal emitter device configured at an electrically powered scooter; and a controller configured to determine information, coded in the wireless signal, that is based on an operator proficiency of an operator of the electrically powered scooter; and to perform, based at least in part on the information that indicates the operator proficiency of the operator of the electrically powered scooter, at least one operation.

Operator proficiency-based infrastructure articles

An optical assembly including an optical element insert molded directly onto an optical stack is provided. The optical stack includes an optical film and may include a liner with the optical film being disposed between the optical element and the liner. The liner, if included, is removable from the optical film without substantial damage to the optical film. An outermost layer of the optical film may be diffusion bonded to a major surface of the optical element. The optical film includes a protective coating having an average thickness of no more than 30 micrometers. The protective coating includes an at least partially cured composition. The composition includes 70 to 96 weight percent of urethane (meth)acrylate compound having an average (meth)acrylate functionality of 2 to 9.5, and 2 to 20 weight percent of (meth)acrylate monomer having a (meth)acrylate functionality of 1 to 2.
