A clipboard is defined by a planar support having a back surface that retains at least one magnet, thereby permitting releasable attachment of the clipboard to a metallic supporting surface. A dry-erasable steel surface is secured to the front of the support and a hinge clip attached enables at least one paper to be secured to the front side of the clipboard as well as at least one magnet.

A display device includes a display device a display panel (e.g. a blackboard or a whiteboard) juxtaposed in a frame. The rear face of the display device is covered by a cover having a height and a planar part. It is possible to selectively attach a reversible I/O unit and a reversible option slot unit to either the right side end or the left side end in the planar part of the rear face of the display device in such a way that input/output terminals are directed to the exterior of the display device. Additionally, an air outlet and an air inlet are formed in the surface of the option slot unit opposite to the rear face joining the planar part of the rear face of the display, thus securing air ventilation. The display device having user friendliness can be easily manufactured using standardized parts with a low manufacturing cost.

A bracelet may be configured with a main body and sized to fit around the wrist of a person with the outer surface area configured and/or prepped as a writeable surface to allow and encourage doodles, notes, artwork, etc. These notes and doodles may be erasable via e.g., a special “eraser” marker. The outer surface and inner surface of the bracelet may be curved to match a general shape, and sized to fit, a human wrist, ankle, leg or arm. The markers held in holsters formed at the proximal and distal ends of the bracelet which may be curled inwardly to hold markers by way of friction fit.

A display control apparatus receives an input of a video signal from an input device and makes a control that causes a video to be displayed on a display apparatus. The display control apparatus includes a capturing unit (410) configured to capture image data that represents a frame image of the input video signal; a signal detector (420) configured to detect whether the video signal is input and issue an instruction to cause the display apparatus to display the video or the frame image on the basis of a result of the detection; and a control unit (400, 430, 440, 450, 460) configured to generate the frame image from the image data captured most recently to cause the display apparatus to display the generated frame image when it is detected that the video signal is not input and the control unit receives the instruction to cause the display apparatus to display the frame image.

An inflatable swimming pool includes a floor and a number of walls defining a pool interior configured to receive water. A drawing board is integrally formed or otherwise coupled to the pool and includes a selectively inflatable frame configured to securely hold a drawing surface configured to enable a user of the pool to draw or write on the drawing board while playing in the pool. A drawing utensil may be provided with the drawing board such as a water soluble crayon. A water sprayer assembly may be integrally formed with or coupled to the pool and include a port connectable to a water source and configured to deliver water from the water source to a sprayer element configured to spray water into the pool.

A handheld message board is provided. The message board includes a front portion and a back portion. The front portion may be made of an erasable writing surface, such as a chalk board or a dry-eraser board. The present invention may further include a handle attached to the back portion so that a user may easily grasp the handheld message board and write on the front portion. The handle includes a strap having a first end and a second end. The first end and the second end are attached to the back portion forming a loop in between to secure a user's hand.

A method of forming a writable erasable area on an object includes selecting a glass sheet having a front surface and a back surface, where the front surface is opposed to and parallel to the back surface. An area of the object where the writable erasable area is to be located is selected. The selected area has a select non-flat shape. The shape of the glass sheet is conformed to the select non-flat shape. The glass sheet is then mounted on the object such that the glass sheet is located at the selected area of the object and conforms in shape to the selected area of the object.

A convenient way to erase a dry-erase writing board is described. One or more erasers are mounted to a shaft that travels along the surface of a dry-erase writing board. A motorized transport mechanism may be used to propel the shaft along the writing board. Other options include a remote control system, handles, a cleaning fluid dispensing system, and a marker holder.
