Abstract:

A broadband loaded antenna and matching network with related methods for design optimization are disclosed. The loaded antenna structures may preferably be either monopole or dipole antennas, but the particular methods and techniques presented herein may be applied to additional antenna configurations. The load circuits positioned along an antenna may comprise parallel inductor-resistor configurations or other combinations of passive circuit elements. A matching network for connecting an antenna to a transmission line or other medium preferably includes at least a transmission line transformer and a parallel inductor. Various optimization techniques are presented to optimize the design of such broadband monopole antennas. These techniques include implementation of simple genetic algorithms (GAs) or micro-GAs. Component modeling for selected components may be effected through either lumped element representation or curved wire representation.

Abstract:

A remote visual inspection system having a video endoscope, a mounting post and a mount. The mount, to which a video monitor is attached, can also accommodate, at any one time, either the video endoscope or the mounting post. The video endoscope has an insertion tube and a scope body. The mount includes a sleeve which defines a central opening into which the scope body and mounting post may extend and has a slot, extending from a first end of the sleeve to a second end of the sleeve, through which the insertion tube may pass. The scope body is provided with a first part (e. g. , a pin hole) of a locking mechanism and a first part (e. g. , an alignment projection) of an alignment mechanism. The mounting post also has a first part (e. g. , a pin hole) of the locking mechanism and a first part (e. g.
