Abstract: A system registers participant information and inter-participant relationship information, and then, at variable times, selects two or more participants with a pre-existing relationship and attempts to establish a communication link between them. At least one of the participants is notified that the communication link will be attempted, shortly before the attempt is made. The identities of the selected participants are withheld from at least one of the participants (and potentially from all of the participants), so the call is a partial surprise (i.e., the participant may know the set of possible people from whom the call could be, but does not know exactly which person or people are calling until he answers the call). A number of applications are described and claimed.

Abstract: A birdfeeder (10) comprising a housing (20) having a hexagonal tube with an open top and an open bottom. Feed-port inserts (30) and perches (40) are securely but removably attached to the housing (20) via keyed contours. A roof (50) and a base (60) are also securely but removably attached to the housing (20).

Abstract: A birdfeeder has a base (20) comprising a frame (30), a floor (40), and a railing (50). The frame (30) can be inexpensively constructed from wooden boards having standard widths and depths. The floor (40) is selectively removable from the rest of the base (20) and can be economically made from a perforation-provided sheet with unturned edges. The railing (50) is situated below the floor (40) but not below the frame (30) so as to accommodate ledge-seating, limb-hanging, or pole-mounting of the birdfeeder.

Abstract: A birdfeeder (10) is provided wherein a housing (20) defines a compartment (21) which is much wider than it is tall or deep. The housing (20) can comprise a plastic tube (30), lateral end lids (40), and a door (50). Perches (60) extend beyond the compartment (21), and a roof (80) is removably attachable to the housing (20).

Abstract: Graphic design panels of the present invention include flexible material with “life-like” images printed thereon that decorate a sectional overhead garage door with a plurality of graphic design panels. The graphic design panels are affixed to the garage door so that a complete image of an object or of scenery is provided. The image selected for displaying on a sectional overhead garage door is divided into a plurality of sections and printed accordingly onto the flexible laminar substrate panels. The flexible laminar substrate panel is a polymeric material, for example, vinyl, and is impregnated with an adhesive on at least one face of the panel. “Life like” images are produced on the graphic design substrate panel by screen printing methods and the printed surface is protected by a graphic protection film.

Abstract: A rebar support device for retaining rebar in a position for reinforcing concrete, and method of using the same is claimed. The rebar support device comprises at least one concrete bonding opening dispersed throughout, at least one rebar support chase with bendable retaining gates, and at least one grade stake support hole. The rebar support device is held in a vertical position for receiving rebar by driving a grade stake through the stake support holes, such that the rebar support device is disposed perpendicularly to the rebar it receives. The rebar is then cradled in one or more of the support chases and retained by a bendable retaining gate incorporated into each rebar support device above each support chase.
