Game Table With Trundle Bed
US Patent:
2007021, Sep 20, 2007
Filed:
Mar 20, 2006
Appl. No.:
11/308378
Inventors:
Eric Wandel - Newburgh IN, US
International Classification:
A47B 83/04, A47C 19/22
US Classification:
005003000, 005002100
Abstract:
An apparatus is disclosed for combining a table and a bed in the same volume of space and utilizing the same floor space. A bed is stored beneath the table—such as a pool, billiard or snooker table, ping pong table, air hockey table, other type of game table, or a table for general use—and can be implemented either while under the table or as an easy to pull out trundle bed.
Wideband Antenna Using Electromagnetic Bandgap Structures
US Patent:
2013027, Oct 24, 2013
Filed:
Oct 17, 2012
Appl. No.:
13/654412

David R. Voltmer - Terre Haute IN, US

International Classification:
H01Q 15/00, H01Q 1/22
US Classification:
343904, 343913
Abstract:
The present invention relates to the field of antennas and specifically to broadband antennas. Planar low-profile antennas over high-impedance surfaces show improved performance compared to that over metal ground planes, but these high-impedance surfaces often operate over narrow bandwidths because current approaches to the design of high-impedance substrates typically employ identical unit cells with the same resonant frequency to produce high-impedance behavior over a relatively narrow frequency range. The present invention provides improved antenna performance over a broader bandwidth through the use of electromagnetic bandgap cells having a size and related resonant frequency that varies with position to the antenna radiating element in order to match the resonance of the element.
