The present invention is a surface mount component carrier comprised of a disk of insulating material having at least two apertures. The disk is substantially covered by a metalized ground surface and includes at least two conductive pads surrounding the apertures, and insulating bands which surround each conductive pad. The insulating bands separate and electrically isolates the conductive pads from the metalized ground surface. A surface mount component, such as a differential and common mode filter, is positioned lengthwise between the two conductive pads and operably coupled to the carrier. Once the surface mount component is coupled to the carrier, the combination can be manipulated, either manually or through various types of automated equipment, without subjecting the surface mount component to mechanical and physical stresses normally associated with the handling of miniature components. The carrier also provides the added benefit of improved shielding from electromagnetic interference and over voltage dissipation due to the surface area of the metalized ground surface. The same concept for the above described carrier is also incorporated into several alternate embodiments, either independently or embedded within electronic connectors.

An improved platinum and method for manufacturing the improved platinum wherein the platinum having a fractal surface coating of platinum, platinum gray, with a increase in surface area of at least 5 times when compared to shiny platinum of the same geometry and also having improved resistance to physical stress when compared to platinum black having the same surface area. The process of electroplating the surface coating of platinum gray comprising plating at a moderate rate, for example at a rate that is faster than the rate necessary to produce shiny platinum and that is less than the rate necessary to produce platinum black. Platinum gray is applied to manufacture a fuel cell and a catalyst.

A flexible electric heating mat includes a grounding substrate sheet arranged in relation to electrical conductors and resistive elements of an electric heater element so as to provide safe and reliable operation of the mat in environments in which the mat will be subjected to moisture and physical stresses.

A cochlear stimulation device comprising an electrode array designed to provide enhanced charge injection capacity necessary for neural stimulation. The electrode array comprises electrodes with high surface area or a fractal geometry and correspondingly high electrode capacitance and low electrical impedance. The resultant electrodes have a robust surface and sufficient mechanical strength to withstand physical stress vital for long term stability. The device further comprises wire traces having a multilayer structure which provides a reduced width for the conducting part of the electrode array. The cochlear prosthesis is attached by a grommet to the cochleostomy that is made from a single piece of biocompatible polymer. The device, designed to achieve optimum neural stimulation by appropriate electrode design, is a significant improvement over commercially available hand-built devices.

A method of monitoring corrosion in a metal sample comprising applying a physical stress to one or more metal samples, placing the metal sample under stress in a sealed vessel, adding one or more fluids to the vessel, measuring the strain on the metal sample over a specified time interval, controlling the environment inside the vessel, calculating the rate of change of the strain measurement over the specified time interval, recording the rate of change of the strain measurement, calculating a moving average of two or more previously recorded rates of change of the strain measurement, and monitoring the moving average to detect damage to the metal sample.

A method of non-thermally ablating undesirable tissue in the body by application of pulsed, bi-polar, instant charge reversal electrical fields of sufficient energy to cause complete and immediate cell membrane rupture and destruction. Energy is delivered through radio frequency pulses of particular frequencies, wave characteristics, pulse widths and pulse numbers, such that enhanced physical stresses are placed on the cell membrane to cause its immediate and complete destruction thereby spilling the entire cell content and membrane constituents into the extracellular space without denaturing proteins so as to enable animmunological response to destroy and remove the target tissue and similarly marked tissue elsewhere in the subject.

The invention relates to the use of extended surface aggregates (ESAs) comprising at least one first amphipathic component, which is a basic aggregate-forming component, and at least one second amphipathic component, which decreases aggregate sensitivity to physical stress, including stress created by enforced passage of said ESAs through pores with an average pore diameter at least 50% smaller than the average diameter of the ESAs before said passage, such that the average ESA diameter change induced by such physical stress is reduced by 10% or more, compared to the diameter change induced by such stress in a reference system comprising just the first or just the second aggregate component, in the manufacture of a pharmaceutical preparation for enduring treatment of pathological mammalian skin conditions, including skin irritation, skin inflammation and/or skin damage after topical application, for modifying skin pigmentation and/or for treatment of skin itch.

A low cost micro-electronic package for MEMS applications includes a package substrate, a MEMS device and a buffer insert which is placed between the MEMS device and the package substrate. The buffer insert has a coefficient of thermal expansion (CTE) which is compatible with the material of the MEMS device and is sufficiently rigid to isolate the MEMS device from thermal, mechanical and other physical stresses applied to the package substrate. In an embodiment, the package is formed as an integrated device which includes both the MEMS device and a signal conditioning integrated circuit, potentially found in the same die. The substrate insert may be made of a material having a CTE value compatible with silicon (Si), such as Kovar, Invar, or an appropriate ceramic material or the like.

The disclosed embodiments relate to a system for use with a model railroad which models, for one or more of the model rail cars, the actual sounds made by the real rail car(s) modeled thereby and having certain characteristics, including general operational characteristics, wear, age, defects, etc., when subjected to various physical stresses/actions during operation. The disclosed system senses similar physical stresses/actions as applied to a model of the rail car during modeled operation thereof and generates corresponding simulations of the actual sounds which would be made by the actual rail car under similar operational conditions, wherein the generation of the simulated sounds may account for the characteristic of the rail car (age, wear, defects), regardless of whether the model of the rail car models those characteristics.
