Abstract:
A projection blackboard having both of an excellent blackboard function and an excellent screen function, and a process for producing the same. The surface enamel layer that is an outermost layer of the enamel layers is formed by using a enameling upper glaze wherein at least titanium oxide coated particles, or a titanium oxide glaze together therewith is blended into a. transparent mat glaze, so as to render the layer an enamel layer having a predetermined color tone, a surface characteristic that the Rz is from 5 to 25 μm and a reflective characteristic that the peak gain is 0.28 or more, or having these properties and a glossiness Gs(75°)of 1 to 30%. This makes it possible to produce a blackboard excellent in both of blackboard function and screen function. The titanium oxide coated particles are preferably particles wherein surfaces of mica particles are coated with titanium oxide.
Abstract:
An image generation device includes a storage unit that stores input object data indicating content information of an input object which is input on a presentation screen, a determination unit that determines a display position located further on an upper side than an input position of the input object on the presentation screen, and an image generation unit that generates a presentation image which is an image displayed on the presentation screen and where the input object is displayed according to the display position determined by the determination unit.
Abstract:
An improved interactive learning board cover is provided. The improved interactive learning board cover may provide protection to the learning board, whereby the cover may stretch over the entire surface of a whiteboard and may be secured at each of the four corners of the board with a sewn pocket thereby allowing securement of the board without the need for additional handles, straps and/or padding.
Abstract:
An improved nutrition monitoring system includes a chart bearing first indicia identifying an individual, and second indicia relating to nutrition groups pertinent to the identified individual. The chart is adapted and constructed to receive marks. A marking mechanism is associated with the chart, the marking mechanism being adapted and constructed to make erasable and replaceable marks on the chart. A mounting mechanism mounts the chart on a surface adjacent to a food preparation and consumption area. The marking mechanism is used to make a mark on the chart in the area of the second indicia to tally consumption of an element of the respective nutrition groups by the identified individual.
Abstract:
A writeboard according to an embodiment of the invention includes plural display cells capable of controlling light within a visible-light spectrum, the display cells being arranged over a display surface of the writeboard. The writeboard also typically includes plural memory cells coupled with the display cells, and plural first receivers arranged with the display cells and the memory cells over the display surface. The first receivers typically are configured to receive transmitted writing information and to communicate the transmitted writing information to corresponding memory cells for storage. Corresponding display cells thus may be selectively activated in accordance with the transmitted writing information.
Abstract:
A motion-detecting note holder is disclosed. Such a note holder may include a message writing surface, a switch, a motion sensor, a note-waiting indicator, and a controller in communication with the switch, the motion sensor, and the note-waiting indicator. When the switch is actuated, the controller, upon receiving a motion-detection signal from the motion sensor, may cause the note-waiting indicator to provide a human-perceptible indication that a note is waiting on the message writing surface. The message writing surface may include an easy erasure message writing surface.
Abstract:
A portably writing box usable primarily by children during long automobile trips. The writing surface is illuminated by three separate lamp mechanisms arranged along three different edges of the writing surface. Light rays are directed onto the writing surface from three different directions, thereby eliminating shadows that might otherwise be generated by a single light source located only long one edge of the writing surface. The writing box preferably includes a transistor radio on the lid of the box, such that the child can choose between writing on the writing surface or listening to the radio.
