Patent number: 8308483Abstract: A rotatable drawing device intended for children. The top and sides of said device are attached and are formed to accept drawing mediums such as chalk, water or dry erase marker used to color, write and draw upon this device. The top of the drawing device has a recessed portion to hold the drawing medium when not in use. The drawing device rests upon and is attached to a base platform on which it rotates. The drawing unit is spaced above the base platform so that the drawing cylinder may rotate about its center axis. Feet adhered to the bottom of the base hold the invention off the floor.Type: GrantFiled: July 28, 2009Date of Patent: November 13, 2012Inventor: Christopher A. Hume

Patent number: 6658098Abstract: One embodiment of the invention includes an apparatus for providing electric power to a telephone across a transmission line where the telephone is coupled to a network device. A power and data coupler (“the coupler”) is coupled to one end of the transmission line. The transmission line is also adapted for transmission of a data signal. The data signal includes telephone signal data for communications with the telephone. The coupler has a data input and a power input. Power from the power input is coupled to the data signal from the data input and the combined power supply current and data signal is coupled to one end of the transmission line. The opposite end of the transmission line is coupled to a power and data decoupler (“the decoupler”). The decoupler has a power output and a data output. Both the data output and power output of the decoupler are coupled to the network device.Type: GrantFiled: September 9, 2002Date of Patent: December 2, 2003Assignee: 3Com CorporationInventors: Christopher Hume Lamb, Peter S.

Patent number: 6587454Abstract: An adaptor supports supplying both telephone signals and data signals over a local area network medium such as a twisted pair wire for Ethernet. The adaptor can be incorporated into a telephone or a computer. The adaptor comprises a first packet port, second packet port and a telephone port. Core logic is coupled to the first and second packet ports and to the telephone port and retransmits network packets which are received on the first and second packet ports and on the telephone port to at least one other of the first and second packet ports and the telephone port. The data processing resources are coupled to the telephone port and to the core logic which translate network packets destined to the telephone port into telephone signals and to translate telephone signals destined to the core logic into network packets. This way, telephone data transmitted as network packets through a network are appropriately routed to the telephone and translated into standard telephone signals.Type: GrantFiled: May 28, 1998Date of Patent: July 1, 2003Assignee: 3Com CorporationInventor: Christopher Hume Lamb

Patent number: 4560079Abstract: An equipment enclosure comprises a frame whereon edge covers can be assembled by means of lugs fitting into corresponding recesses in the frame. Each of the edge covers comprises a groove overhanging the frame on either side to form a continuous channel all around. Covers are slidably insertable into the continuous groove to trap the lugs in the recesses to prevent the removal of the edge covers, the edge covers in turn co-operating to retain the side covers. A back cover is boltable onto the frame to prevent the sliding out of the side covers and to complete the assembly of the enclosure. The edge covers are provided with projections and slots which are insertable one into the other between adjacent covers to lend added strength to the enclosure. In a modification to the invention an openable portion of the enclosure is provided.Type: GrantFiled: February 2, 1984Date of Patent: December 24, 1985Assignee: Burroughs CorporationInventors: Michael J.
