| 20110255255 | HOUSING FOR A CIRCUIT THAT IS TO BE IMPLANTED IN-VIVO AND PROCESS OF MAKING THE SAME - The present invention provides a biocompatible circuit assembly that includes a circuit encased within a housing. In some embodiments, the housing is a PMMA housing and before the circuit is enclosed within the housing the circuit is encased within a brick of epoxy. | 10-20-2011 |
| 20110081727 | Oxidation Resistant Indicator Molecules - Compounds having enhanced oxidation stability are disclosed. The compounds have an aryl boronic acid residue having one or more electron withdrawing groups on the aromatic moiety which contains the boronic acid residue, such that the molecule has enhanced oxidation resistance as compared to a corresponding molecule without the one or more electron withdrawing groups. | 04-07-2011 |
| 20110064617 | ELECTRO-OPTICAL SENSING DEVICE WITH REFERENCE CHANNEL - An electro-optical sensing device for detecting the presence and concentration of an analyte in a liquid or gaseous medium includes a pair of indicator elements positioned to receive radiation from a radiation source and transmit radiation to a pair of photosensitive elements. The indicator elements each contain indicator molecules having an optical characteristic responsive to the presence of an analyte; however, one of the indicator elements is covered by an analyte-impermeable chamber that renders the indicator element insensitive to the presence of the analyte in the medium outside the chamber so that it can be used as a reference to cancel environmental and systemic variables that affect both indicator elements. The chamber preferably holds an analyte-containing fluid in contact with the reference indicator element so that the indicator elements operate under nominally identical conditions. The indicator element used to measure the analyte in the external medium is preferably also covered, but in a manner that provides direct contact between the analyte and the indicator element. | 03-17-2011 |
| 20090146078 | SYSTEMS AND METHODS FOR EXTENDING THE USEFUL LIFE OF OPTICAL SENSORS - The present invention provides a method for increasing the lifetime of an optical sensor. In one aspect, the method includes the step of configuring the optical sensor so that the duty cycle of sensor's radiant source is less than 100% over a continuous period amount of time when the sensor is periodically obtaining data regarding an analyte. By operating the sensor according to the above inventive method, the indicator molecules of the optical sensor are not excited during the entire continuous period of time during which the sensor is needed to provide data regarding the presence or concentration of a substance. Thus, the method increases the life of the indicator molecules. | 06-11-2009 |
| 20090039286 | SYSTEM AND METHOD FOR ATTENUATING THE EFFECT OF AMBIENT LIGHT ON AN OPTICAL SENSOR - The present invention provides systems and methods for attenuating the effect of ambient light on optical sensors and for measuring and compensating quantitatively for the ambient light. | 02-12-2009 |
| 20080218759 | LIGHT EMITTING DIODE FOR HARSH ENVIRONMENTS - A light emitting diode for harsh environments includes a substantially transparent substrate, a semiconductor layer deposited on a bottom surface of the substrate, several bonding pads, coupled to the semiconductor layer, formed on the bottom surface of the substrate, and a micro post, formed on each bonding pad, for electrically connecting the light emitting diode to a printed circuit board. An underfill layer may be provided between the bottom surface of the substrate and the top surface of the printed circuit board, to reduce water infiltration under the light emitting diode substrate. Additionally, a diffuser may be mounted to a top surface of the light emitting diode substrate to diffuse the light emitted through the top surface. | 09-11-2008 |
