Abstract: An electromagnetic radiation decoupler for decoupling radiation in the wavelength range ?min to ?max. The decoupler has a first conductor layer in contact with a dielectric layer which comprises at least one area of absence and the thickness of the decoupler is less than ?min/4n, where n is the refractive index of the dielectric. The dielectric layer may be sandwiched between two conductor layers, one of which has the structure described above. The invention is also directed to methods of using and various articles comprising such a decoupler.

Abstract: Apparatus and methods for providing a substantially surface independent tagging system are disclosed. A resonant dielectric cavity is defined between upper and lower conducting layers, and closed at one end by a conducting base portion. Incident radiation couples into the cavity and is resonantly enhanced. An electronic device or tag paced at the edge of the cavity experiences a high electric field strength on account of this enhancement and is driven into operation.

Abstract: Apparatus capable of enhancing an incident electric field to drive an electromagnetic tag (124) into operation, comprising a resonant dielectric cavity which extends out of a single plane defined between two conducting surfaces (102, 104, 106). The cavity may extend over two or more layers, and can adopt C or S shaped or spiral profiles.

Abstract: A device capable of enhancing an electric field to drive an electromagnetic tag into operation is switchable between states to control operation of the tag. Enhancement is provided by a dielectric cavity structure defined between first and second conducting layers. Different states of the device may have different resonant frequencies and read ranges according to the characteristics of the enhancement. As such a container can be provided which includes a tag which switches states on opening, allowing improved tracking characteristics.

Abstract: This invention is a novel saddle that comes in two embodiments, a vertical saddle and a horizontal saddle. Each saddle is configured to hold a power harness (or assembly of wires) and a signal harness, also an assembly of clustered wires. The saddle eliminates or greatly reduces the occurrence of electrical cross talk between these two harnesses by electrically insulating them from each other while securing each in place by a spring holder. These saddles greatly reduce electrical interference while significantly reducing installation time of the assembly. While this invention is described as used in a xerographic system, the saddle can be used in any system containing large bundles of electrical wires or cables.
