Abstract: An MRI-compatible, fixed-rate (VOO) pacemaker includes a self-contained power source and a pulse generator housed at the proximal end of a photonic catheter in a first enclosure. Electrical pulses output by the pulse generator are converted into light energy and directed into the proximal end of the photonic catheter. The photonic catheter includes an optical conduction pathway over which is formed a covering of biocompatible material. Light entering the proximal end of the photonic catheter is transmitted through the optical conduction pathway, where it is collected and converted back to electrical energy at a second enclosure located at the distal end of the photonic catheter. The second enclosure houses an opto-electrical transducer that converts the optical pulses to electrical pulses and delivers them to bipolar heart electrodes.

Abstract: An MRI-compatible, fixed-rate (VOO) pacemaker includes a self-contained power source housed at the proximal end of a photonic catheter in a first enclosure. Low energy continuous electrical power is delivered from the power source. This electrical power is converted into light energy and directed into the proximal end of the photonic catheter. The photonic catheter includes an optical conduction pathway over which is formed a covering of biocompatible material. Light entering the proximal end of the photonic catheter is transmitted through the optical conduction pathway, where it is collected and converted back to electrical energy at a second enclosure located at the distal end of the photonic catheter. The second enclosure houses a pulse generator that stores electrical energy and periodically releases that energy to deliver electrical pulses to bipolar heart electrodes.

Abstract: A controllable, wearable MRI-compatible, fixed-rate (VOO) pacemaker includes a self-contained steady state power source and an oscillator housed at the proximal end of a photonic catheter in a first enclosure. Continuous electrical energy is delivered from the power source and electrical pulses are delivered from the oscillator. The continuous electrical energy and electrical pulses are converted into respective continuous and pulsing light energy and directed into the proximal end of the photonic catheter. The photonic catheter includes optical conduction pathways and a covering of biocompatible material. Light entering the proximal end of the photonic catheter is transmitted through the optical conduction pathways, where it is collected and converted back to electrical energy at a second enclosure located at the distal end of the photonic catheter.

Abstract: The present invention is a method and apparatus for embedding or associating additional information with a document substrate. More particularly, the various embodiments described herein are intended to improve the amount and availability of information associated with a document or other printed publication. The additional information is preferably provided in one or more of a number of embodiments employing embedded or affixed memory media and devices.

Abstract: An implantable device used to monitor and maintain at least one physiologic function, which is capable of operating in the presence of damaging electromagnetic interference. The implantable device includes primary and secondary modules, each independently protected from EMI damage via at least one shielding and/or filtering, and a non-electrical communication device for communicating in at least one direction between the primary and the secondary modules. The primary module, in response to input from electrical sensing leads, activates the secondary module in a failsafe mode. In the failsafe mode, the secondary module carries out a physiologic function upon activation and in the presence of electromagnetic interference.

Abstract: An apparatus for the electronic display of information, where the apparatus is a substrate incorporating a digital recording medium attached to or embedded within the substrate. The substrate further includes a flexible-substrate display located on an exposed surface of the substrate, where the display is a medium capable of selectively displaying one of at least two possible colors at each pixel location thereon in order to produce a substrate medium that may be modified in accordance with a user's selection.

Abstract: A method and apparatus for efficiently analyzing information on a computer is provided. The information contains information items where each information item has a plurality of attributes. The information is re-organized based on the attributes and displayed in graphical form on a computer display screen. By viewing the information in graphical form, a user can quickly analyze the information to determine trends or qualities. In addition, the graphical form provides a way for the user to quickly identify the information items most relevant to specific criteria.

Abstract: A composition comprising a family of oligonucleotides all of the same length, said family defined by a nucleotide sequence formula containing six to eight nucleotide positions, one to three of said positions of the formula identifying positions of nucleotide variation among the family members, the remaining nucleotide positions each identifying a nucleotide that is the same in all members of the family.

Abstract: An LMS adaptive control loop module for reducing the effects of received interference includes a single antenna coupled to a first hybrid for generating a reference channel and an auxiliary channel. The auxiliary channel provides I/Q signals from a second hybrid and I/Q drive signals from I/Q correlation multipliers which are used to weight the I/Q signals from said second hybrid. The weighted signals and the reference channel signals are combined and provide an output.

Abstract: The ridge of each pleat of pleated fabric is supported by a thin horizontally disposed blade. The blades are moved to a compacted position so that only the ridges are exposed above the blades. Then the ridges are printed with a pigment which is then cured. Thereafter the fabric is removed from the blades.
