Abstract: A directionally-sensitive device (10) for detecting and processing vibration waves includes an array of polymeric optical waveguide resonators (28) positioned between a light source (24), such as an LED array (24), and a light detector (26), such as a photodiode array (26). The resonators (28) which are preferably oriented substantially perpendicularly with respect to incoming vibration waves, vibrate when a wave is detected, thus modulating light signals that are transmitted between the light source (24) and the light detector (26). The light detector (26) converts the modulated light into electrical signals which, in a preferred embodiment, are used to drive either the speaker of a hearing aid (32) or the electrode array (39) of a cochlear implant. The device (10) is manufactured using a combination of traditional semiconductor processes and polymer microfabrication techniques.

Abstract: Improved protection circuits are provided for use as voltage overload protection circuits, ESD protection circuits for RF input pins, and unit protection cells for distributed amplifiers. Preferably, the protection circuits include a positive threshold voltage trigger used to trigger a switch wherein the trigger includes a diode string in series with a resistor and the switch includes a bipolar transistor switch in series with a single reverse diode. Alternatively, the trigger includes a diode string in series with a single diode and a single resistor, and is used to trigger a Darlington pair transistor switch in series with a single reverse diode. In another embodiment, a Darlington pair transistor switch is triggered by a capacitor. In use with distributive amplifiers, the ESD protection circuits are preferably absorbed inside the artificial transmission lines of the distributed amplifier.

Abstract: A miniature wireless pressure sensor has an inductor and a capacitor. The inductor and the capacitor form a L-C resonator with a resonate frequency. The inductor's inductance is affected by a slidable electro-magnetic element. When an outside pressure is applied onto the element, it causes the element to move and such movement changes the inductance of the inductor. Because of that, the resonate frequency is changed. Therefore, the change in resonate frequency indicates a change in the outside pressure. The L-C resonator is calibrated to correlate with the outside pressure. Such a miniature wireless pressure sensor facilitates the monitoring of physiological pressure in different part of human body such as eyes and cranium.

Abstract: A plate manufactured to enable samples of cells, micro-organisms, proteins, DNA, biomolecules and other biological media to be positioned at specific locations or sites on the plate for the purpose of performing addressable analyses on the samples. Preferably, some or all of the sites are built from a removable material or as pallets so that a subset of the samples of interest can be readily isolated from the plate for further processing or analysis. The plate can contain structures or chemical treatments that enhance or promote the attachment and/or function of the samples, and that promote or assist in their analyses.

Abstract: Polymer-based biomaterials are popular due to ease of fabrication and low costs. However, many polymer substrates have undesirable surface properties. The invention provides a procedure to covalently apply a graft polymer to the surface of a polymer substrate by ultraviolet graft polymerization. The graft polymer is formed from monomers such as PEG, AA, monomethoxy acrylate PEG, HEMA, or DMA. Also, mixed monomers may be used to create the graft and the surface properties of the graft may be tailored for different properties, including hydrophobicity, friction coefficient, electroosmotic mobilities and electrophoretic separations. The invention has particular utility in tailoring surface chemistries in ocular lenses and polymer microdevices. I. II.
