20110180884 | METHODS, APPARATUSES, AND SYSTEMS FOR MICROMECHANICAL GAS CHEMICAL SENSING CAPACITOR - A capacitive chemical sensor, along with methods of making and using the sensor are provided. The sensors described herein eliminate undesirable capacitance by etching away the substrate underneath the capacitive chemical sensor, eliminating most of the substrate capacitance and making changes in the chemical-sensitive layer capacitance easier to detect. | 07-28-2011 |
20110316054 | Method, Apparatus, and System for Micromechanical Gas Chemical Sensing Capacitor - A method for fabrication of capacitive environment sensors is provided in which the sensor elements are integrated in a CMOS structure with electronics through the use of complementary metal oxide semiconductor (CMOS) fabrication methods. Also provided are environment sensors fabricated, for example, by the method, and a measurement system using the environment sensors fabricated by the method. The described method includes etching away one of the metal layers in a CMOS chip to create a cavity. This cavity is then filled with an environment-sensitive dielectric material to form a sensing capacitor between plates formed by the metal adhesion layers or an array of contacts from other metal layers of the CMOS structure. This approach provides improved sensing capabilities in a system that is easily manufactured. | 12-29-2011 |
20140213891 | APPARATUS AND METHOD FOR IMPLANTATION OF DEVICES INTO SOFT TISSUE - Apparatus and method for surgeon-assisted rapid surgical implantation of devices into soft tissue. The apparatus comprises several subsystems that enable the referencing of the spatial position and orientation of the device being implanted with respect to the soft tissue into which it is being implanted and then the controlled implantation of the device at a predefined speed with higher positional accuracy and precision and a reduction in soft tissue damage, provided by ultrasonic assisted motion, compared to current state-of-the-art implantation methods and devices. The method includes automated loading of the device being implanted into a clamping mechanism from a cartridge holding a number of implants, referencing of the device position and orientation, referencing of the surface of the tissue into which the device is being implanted, monitoring of the tissue motion, identification of desirable implant location based on the soft tissue profile, allowance of surgeon selection and fine adjustment of the final implant location, high-speed implantation, device release and implant actuator retraction. | 07-31-2014 |

20130131482 | FABRICATION, METHODS, APPARATUSES, AND SYSTEMS FOR ULTRA-COMPLIANT PROBES FOR NEURAL AND OTHER TISSUES - Methods, systems and apparatuses of ultra-miniature, ultra-compliant probe arrays that allows for design flexibility to match the stiffness of the tissue it is being applied to, such as the brain tissue, in all three axes (x, y and z), with interconnect cross section smaller than cell dimensions. Stiffness matching requires specific geometric and fabrication approaches, commonly leading to ultra-thin probe wires. Sizing of the electrodes for specific cell dimensions reduces glial formation. Further reduction in stiffness is obtained by incorporating different geometric features to the electrode, such as meandering the electrode wires. The small thickness and geometric features of the wires commonly result in very high compliance. To enable effective insertion of the probes to the tissue, the present invention uses stiff biodisolvable and/or biodegradable polymers, including single use or combinations of carboxymethyl cellulose, polyvinylpyrrolidone, polyvinyl alcohol, maltose, other sugar molecules, polylactic acid and its co-polymers. | 05-23-2013 |

20080220666 | Electrical terminal having a compliant retention section - An electrical terminal of the type to be inserted into an aperture of an electrical panel member is provided. The electrical terminal includes a base and an insertion portion extending from the base to a first end. A slit formed through the insertion portion and extending from or between the base and between the first end defines a compliant portion having a first leg and a second leg.
