Title: Communications system
Inventor: SMITH STEPHEN H
IPC: H04B7/10
Filed: 1998-05-08
Granted: 2007-12-04
Abstract: A communications system (10 and 12) in which a communications channel is defined at least in part by an electromagnetic wave (78) having a carrier frequency and an electric field vector, the extremity or terminus of which traces a non-linear periodic path at a rotation frequency less than the carrier frequency and greater than zero from the perspective of an observer looking into the axis of propagation of the wave. The transmitter (10) of the communications system launches a wave (78) having such characteristics and modulated with information in a suitable manner. The receiver (12) of the communications system is sensitive to the periodic path and rotation frequency.  The combination of the periodic path and the carrier frequency provides selectivity that can be used to define multiple communications channels.

Title: Spill proof snack container
Inventor: VOLOSHIN CORRI
IPC: B65D25/02
Filed: 2000-12-07
Granted: 2006-12-19
Abstract: The present invention provides a spill-proof container having a two-panel cover such that an upper panel is stationary, while a lower panel is enabled for rotational motion relative to the upper panel. As each panel has an aperture in it, and the lower panel provides a device for manual actuation of the rotational motion of the lower panel relative to the upper panel, the invention enables one to reach inside of the container when the lower aperture is positioned by the rotative motion adjacent to the upper aperture. Therefore, the food is held fresh and protected from exposure to the undesirable moisture or dryness of the fresh air, while it is easily accessible without removal of the container's cover. This objective is further enhanced by a resilient, snap-action engagement of an L-shaped annular container cover rim with the top annular rim of the container. Additionally, the lower panel aperture is provided with a flexible surface which is split by radial slits into flexible fingers. The flexible fingers are such that they are capable of bending into the container when a hand reaches inside of the container for food, and resiliently return to their initial planar position, automatically closing the container when the hand is removed. Consequently, no food will spill out if the containeris tilted too far or accidentally tipped over.
