20120001648 | Capacitance Sensors - A sensor assembly includes a housing assembly, an electrode arrangement and a diaphragm having a fixed portion secured to the housing assembly and an active portion movable relative to the electrode arrangement in response to a differential pressure applied to opposite sides of the diaphragm. The fixed portion of the diaphragm is secured at one or more locations relative to at least a portion of the housing assembly; and at least one groove is formed in the fixed portion of the diaphragm between the locations at which the diaphragm is fixed relative to the housing assembly and the active portion so as to relieve any stress on the active portion of the diaphragm. A method of making the sensor assembly is also disclosed. | 01-05-2012 |

20100267590 | Reaction Surface Array Diagnostic Apparatus - A reaction surface array diagnostic apparatus and method of making the same includes a substrate carrying a plurality of reaction surfaces, a plate and a gasket, each having a plurality of through bores, alignable with one of the reaction surfaces and forming a fluid tight well about each reaction surface when the gasket and the plate are sealingly affixed to the substrate to form a stack. Clamp members engage opposite side edges of a stack to compress the gasket. A plurality of side-by-side disposed clamped stacks of plates, gaskets and substrates are mounted in a tray in the standard footprint of a microtitre plate. Alternately, the plate and the gasket are combined into a single plate formed of a flexible material having an adhesive on one surface. | 10-21-2010 |

20140206580 | PROTEIN MICROARRAY ASSAY IMAGER - An approach is described that combines distinct properties of a specialized porous nitrocellulose film (PNC) with quantum nanoparticles to create an improved assay and detection sensitivity, permitting the development of a camera-based imaging system for fluorescent detection of macromolecules in microarray format. The two properties of PNC that facilitate the approach are an extraordinarily high binding capacity and a newly observed internal scattering of light. Quantum nanoparticles complement these PNC properties by providing a higher level of emitted light than the fluorescent dyes in common microarray use. Overall, the approach allows for instrument cost savings, reduced imaging time, and the ability to remotely image. | 07-24-2014 |

20130299762 | Removable Handrail Assistance Device - A removable handrail assistance device includes a bracket and a handle extension. The bracket may be affixed to a wall or other essentially immobile structure. The handle may be easily inserted into, or removed from, the bracket. The inserted handle extension is capable of supporting a user who holds onto the handle for support while, for example, climbing up or down one or more stairs. | 11-14-2013 |
20150021536 | Removable Reversible Handrail Assistance Device - A removable handrail assistance device includes a bracket and a handle extension. The bracket may be affixed to a wall or other essentially immobile structure. The handle may be easily inserted into, or removed from, the bracket. The inserted handle extension is capable of supporting a user who holds onto the handle for support while, for example, climbing up or down one or more stairs. The bracket may be reversible, thereby allowing the handle to point in an opposite direction when inserted. | 01-22-2015 |
