Abstract: In one embodiment, the invention is directed to a remote display unit and related methods, the remote display unit including a display screen located remotely from a navigation unit for displaying location information from the navigation unit to a remote user, a display processor for controlling the appearance of the display screen, and communication elements for providing a wireless communication link between the navigation unit and the remote display unit. In a further embodiment, the invention is directed to a navigation system and related methods, the navigation system including, a navigation unit and a remote display unit. The remote display unit includes a display screen for displaying location information from the navigation unit to a remote user, a display processor for controlling the appearance of the display screen, and communication elements for providing a wireless communication link between the navigation unit and the remote display unit.

Abstract: The invention, in one embodiment, is directed to a lid securing device. The device includes a first end adapted to interfit over a first handle of a container, a second end adapted to interfit over a second handle of the container, and an intermediate portion extending between the first end and the second end and adapted to engage a lid to exert a securing force between the lid and a container. Optionally, a portion of the device is elastic to further enhance the securing force between the container and the lid.

Abstract: A portable distance tracking system for use by a player on a playing field wherein the playing field includes at least a first landmark and wherein the system comprises at least one mobile interface unit. The mobile interface unit includes a memory element, position interface electronics, a data processor, and a player interface. The memory element stores digitized map representations of playing fields. The position interface electronics receive position indicative signals from and external source, wherein the position indicative signals are representative of a geographical location of the mobile interface unit. The data processor couples to the memory element and to the position interface electronics and correlates the geographical location to a field location of said mobile interface unit on said playing field. The processor also determines the distance from the mobile interface unit to the first landmark.
