The present invention provides tablets with interconnection features and a system of multiple tablet assemblies removably interconnected to one another. The tablets may be removably mounted to a vertical surface or positioned on a horizontal surface. Features of the present invention allow a user to remove or move one tablet from the system without disrupting or moving the other tablets.

Examples of a transparent whiteboard display are disclosed. In one example implementation according to aspects of the present disclosure, a transparent whiteboard display causes digital content to be viewable on the transparent whiteboard display when the transparent whiteboard display is in a display mode. The transparent whiteboard display also causes analog content to be viewable on the transparent whiteboard display when the transparent whiteboard display in a transparent mode.

The invention relates to glass articles suitable for use as writable erasable marker boards. More particularly, disclosed is a strengthened glass article suitable for use as a writable erasable marker boards, wherein the glass sheet exhibits an ion exchanged glass having a front surface and a back surface and exhibiting a thickness of less than 2.0 mm and having a depth of layer (DOL) greater than 20 microns and a surface compressive strength of at least 300 MPa. The strengthened glass article exhibits certain optical properties which render it particularly suitable for use as a writable erasable marker boards electronic including: (1) shadow parallax to thickness ratio of less than 1 measured at a 60 degree incident light angle and for an index of refraction n; and, (2) a haze of less than 50%. Further disclosed is a markerboard with improved magnetic force attributes; sufficient to hold weak magnets in place.

A writing board for mounting to a structure includes a main panel made from transparent material, the main panel having a front writing surface and a rear surface. There is at least one holding device formed in the rear surface for holding a background material. The front writing surface is flat and the entire background material is completely visible through the main panel.

A new design for a dry-erase board allows for writing on a clear top surface or a second surface under the clear top surface. The dry-erase board includes an insert positioned between the clear top surface and a second surface, the insert being protected by the clear top surface.

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.
