A reusable writing surface is provided having a board having a front side and a rear side. A plurality of magnets is positioned on the rear side, wherein the plurality of magnets is configured to magnetically attach to a plurality of removable magnetic legs. The plurality of magnets are positioned such that the plurality of removable magnetic legs are configured to stand the reusable writing surface in either a vertical orientation or a horizontal orientation depending on which magnets of the plurality of magnets each magnetic leg attaches.

A display assembly, having a base comprised of polymeric material, and having a front wall of at least one hundred square centimeters in area, and a rearward-extending base peripheral wall of at least 0.5 cm height. The front wall has raised regions and recessed regions that extend at least as far back as the peripheral wall at its furthest rearmost extent, so that when the base is placed against a flat surface the back of the recessed regions touches the flat surface. A polymeric cover is adapted to tension fit to the base, the polymeric cover including a generally transparent front wall. Translucent display media interposed between the base and the cover and a set of energy efficient lighting devices disposed in the recessed regions.

A trifold presentation board assembly for securing and protecting a display includes a panel that comprises a first section and a pair of second sections. Each second section is hingedly coupled to a respective opposing edge of the first section and is positioned to be pivoted relative to the first section to selectively reposition the panel from an extended configuration to a folded configuration. A forward face of each of the second sections is positioned proximate to a front face of the first section so that the pair of second sections covers the front face of the first section. A plurality of couplers that is coupled to a rear surface of the panel is positioned to be selectively mutually coupled when the panel is in the folded configuration. The panel is configured to shield and protect a display article that is coupled to a front surface of the panel.

A method of reusing a notebook provides a notebook having a synthetic-paper page. The method also provides a thermochromic ink pen which, when used to write on the synthetic paper page, leaves thermochromic ink markings. The method further provides a moisture carrier configured to have a liquid diffused therein. The moisture carrier is configured to erase the thermochromic ink markings from the synthetic-paper page by contacting the thermochromic ink markings when the moisture carrier is moist. The method then writes with thermochromic ink on at least a portion of the synthetic-paper page. Liquid is diffused in the moisture carrier, and the portion of the synthetic-paper page having the thermochromic ink is wiped with the moist moisture carrier, such that the thermochromic ink is erased from the synthetic-paper page.

A garment having an outer surface not designed for writing has at least one rewritable area comprising a layer of rewritable material deposited directly onto a selected region of the outer surface. One or more permanent artworks may be deposited onto the garment prior to deposit of the rewritable layer, which may be contiguous or non-contiguous. A stencil is provided for allowing a user to write on rewritable areas while protecting adjacent areas of the garment. In one method for forming the rewritable area, a first portion of a permanent artwork and a second portion of the permanent artwork are successively deposited on the garment, followed by curing the permanent artwork and depositing a rewritable area on the garment.

An evidence ecosystem that includes a capture system that detects physical properties in the environment around the capture system and captures data related to the physical properties. The capture system analyzes the captured data in accordance with patterns to detect characteristics and patterns in the captured data. Upon detecting a characteristic or a pattern, the capture system records the identified data and alignment data that identifies the location of the identified data in the captured data. The capture system sends the captured data, identified data, and alignment data to an evidence management system for use in generating reports and producing redacted copies of the captured data for distribution or presentation.

An expandable table comprises first and second table surfaces connected by a first hinge at their adjoining short sides. First and second legs are fixed to an underside of the first table surface to support the first table surface. A third leg is fixed to an end of a slidable bar or mechanism wherein the slidable bar or mechanism is installed on an underside of the first table surface, wherein the slidable bar or mechanism is configured to be slid out from under the first table surface wherein the third leg provides support for the second table surface when the second table surface is unfolded and wherein the slidable bar or mechanism is configured to be slid under the first table surface wherein the third leg rests adjacent to the first leg when the second table surface is folded to lie on top of the first table surface.
