Abstract: A pet co-sleeper is designed to be connected to a human's bed for use by small to medium sized animals. Pets such as dogs and cats can use this sleeper to sleep beside their owners instead on of the bed. The pet co-sleeper has a frame which is substantially rectangular in shape. The frame has three horizontal bars forming a three-sided top frame and a fourth horizontal bar on the fourth side is lower than the other three horizontal bars. Fabric materials attached to the frame form a floor, four side walls and a horizontal divider located just below the fourth horizontal bar. A first mattress is placed over the horizontal divider to form a sleeping surface. A second mattress is placed on the fabric floor, such that the four side walls, the second mattress and the horizontal divider form a pet house.

Abstract: A clearinghouse system for inter-gallery trading of artworks is described. A central database stores digital images and metadata about artworks owned by all member galleries. The data is duplicated and stored in local databases at each member gallery. Customers at a first gallery can view images and information about artworks owned by other galleries using display devices installed at the first gallery. If the customer is interested in an artwork owned by a second gallery, a price request is transmitted from the display device to a remote clearinghouse management server. The clearinghouse management server transmits the price to the first gallery via an information receiver other than the display device. The first gallery may then quote a price to the customer by adding a markup to the price received from the clearinghouse management server. A purchase request can also be generated from the display device.
