The disclosure relates to the technical field of an electronic device, and provides a case and an electronic device. The case includes: a case body, which has a plurality of case sides, a cavity enclosed by the case sides and configured to accommodate the electronic device; a plurality of vents, which are disposed on at least part of the case sides and configured to ventilate between the case cavity and an external space; and a water retaining mechanism, which is on the inner wall of the case body and positioned at the vents.

Display sign apparatuses provide a visual indicator for drivers to quickly and easily find the location for a delivery, such as for the delivery of packages (such as, for example, from Amazon® or eBay®) and food or other like items, or for pick-up and drop off points for rideshare companies. Additional embodiments provide electronic features that allow a driver to quickly and easily determine a location, such as by using wireless communication protocols, such as, for example, RF tags, Bluetooth enabled communication modules, or other like electronic elements. Methods of using the same are further provided.

Methods for installing an advertising unit at an installation area of a surface are provided. The installation area is cleaned. One or more holes are formed in the installation area. The adhesive is applied at the installation area. The advertising unit is deposited at the installation area atop the adhesive. A fastener is passed through at least a portion of the advertising unit into each of the one or more holes. The adhesive is cured.

Systems and methods for providing solar-generated power to a display unit mounted to a vehicle are provided. One or more mounting supports connect a housing for an electronic display to the vehicle. A solar energy harvesting device is secured to an upper portion of the vehicle and is electrically connected to the electronic display.

Disclosed herein are various clusters. A cluster comprises processing nodes that have supervisory roles and subordinate roles. A node in the cluster can have a supervisory or a subordinate role. The cluster can self-orchestrate its roles. The roles of the nodes can be assigned and/or reassigned (e.g., autonomously and/or automatically) by the cluster. Such system may achieve automatic commissioning of the cluster(s), e.g., in a facility.

An optical projection device for projecting a linear image is disclosed. Light emitted by an array of light emitting diodes arranged along an array axis is focused in at least a direction perpendicular to the array axis and diffused in a direction parallel to the array axis, thereby generating a linear image in which light from adjacent light emitting diodes is spatially overlapped. In some embodiments, the focusing and diffusion of the light is performed by a Fresnel lens and a lenticular lens, respectively. The optical projection device may be employed to virtually mark a surface, such as a floor in an industrial setting. High power light emitting diodes may be employed to generate a linear image having an illuminance of at least 4000 lux that is focused to a distance between 7.5 and 20 feet.

A faceted screen system includes a curved backing surface, a first planar panel coupled to the curved backing surface, and a second planar panel coupled to the curved backing surface. The first planar panel and the second planar panel are angled towards a hypothetical focal point of the curved backing surface. The faceted screen system also includes a first plurality of light sources disposed on the first planar panel and a second plurality of light sources disposed on the second planar panel. Individual light sources of the first plurality of light sources are oriented at respective different angles relative to the first planar panel to emit light towards the hypothetical focal point. Individual light sources of the second plurality of light sources are oriented at respective different angles relative to the second planar panel to emit light towards the hypothetical focal point.

The application belongs to the technical field of LED display screens, and particularly relates to an outdoor LED display. The Outdoor LED display comprises a box body, a display module and a plurality of control assemblies; the display module comprises a plurality of sub-modules, and each sub-module is provided with a control assembly; the box body comprises a frame and a panel installed on the frame, and the display module is connected at one end of the frame away from the panel; the panel, the frame, and the display module form an installation space for installing the control assembly. In this application, each sub-module is installed with a corresponding control assembly, and the control assembly can control the corresponding sub-module to display, thereby enhancing the display effect of the outdoor LED display.

Disclosed herein as methods, apparatuses, non-transitory computer readable media, and systems relating to reduction and/or identification of one or more health risks in a facility. For example, by sensing a bodily characteristic of an individual in a facility, e.g., by sensing at least one environmental characteristic. For example, by sensing surface cleanliness. For example, by tracking personnel in the facility. For example, by suggesting routes in an enclosure based at least in part in personnel concentration in the facility. Disclosed herein as methods, apparatuses, non-transitory computer readable media, and systems relating to monitoring occupancy of a facility.
