Abstract: Portable privacy spaces are described that include an open door of a vehicle, and an opaque sheet attached to a first fastener and a second fastener. The first fastener is attached to the open door of the vehicle and the second fastener is attached to another surface of the vehicle. The door, the sheet, and the vehicle form a perimeter for the privacy space. Also, methods of forming a privacy space are described that include the steps of opening a first door of a vehicle, and attaching a first fastener to the open door, where the first fastener is also attached to an opaque sheet. A second fastener is attached to another surface of the vehicle, where the second fastener is also attached to the opaque sheet. The open door, the opaque sheet and the rest of the vehicle form the privacy space.

Abstract: An interactive educational apparatus, ideally suitable for children. A set of symbol pieces, preferably in the form of letter blocks are provided. An interface board is provided for accommodating one or more selected symbol pieces and a sensor on said interface board generates a signal identifying each symbol piece when placed on the interface board. Media files are stored on a storage medium and each media file has an associated tag. A processor is programmed to match a search key represented by one or more selected symbol pieces with the tags. A display device displays one or more media files having identifier tags matching the search key represented by said selected symbol pieces. These identifier tags provide a way to match up the media files with each search key generated by placement of the symbol pieces on the interface board.

Abstract: A lamp that allows a user to adjust parameters to control emitted white light, specifically quality, intensity and color temperature. Under such control, the lamp can match, complement, or augment ambient or available natural or artificial light. In specific embodiments, the lamp uses high power, high CRI, white LED sources; integral thermal management that also functions as LED structural support; integral optics (secondary lenses) with accommodation for diffusing elements; and manually responsive controls.

Abstract: The invention relates to a display system having one or more collapsible crates and at least one creative panel that can be employed to display to various types of items, products, goods or information for sale or non-sale display. The collapsible crates of the invention are less expensive to make and ship, and can be reused over and over again, thus, further decreasing shipping costs over the life of the display system.
