Assignee:

UT-Battelle, LLC - Oak Ridge TN

International Classification:

C12M 134

US Classification:

4352872, 435 6, 435 911, 435 912, 435183, 536 221, 536 231, 536 243, 536 2431, 536 2432, 536 2433

Abstract:

The present invention discloses a self-contained miniature DNA biosensor designed to detect specific molecular targets, particularly suitable for detection of nucleic acids. For example, hybridized DNA may be detected without external monitoring or signal transmission. The miniaturized biosensor is a biochip comprising multiple biological sensing elements such as DNA probes, excitation microlasers, a sampling waveguide equipped with optical detectors (fluorescence and Raman), integrated electro-optics, and a biotelemetric radio frequency signal generator. The novel integrated circuit biochip microsystem (ICBM) is suitable for gene analysis and will allow rapid, large-scale, and cost-effective production of gene biochips.

Abstract:

A monolithic sensor includes a reference channel and at least one sensing channel. Each sensing channel has an oscillator and a counter driven by the oscillator. The reference channel and the at least one sensing channel being formed integrally with a substrate and intimately nested with one another on the substrate. Thus, the oscillator and the counter have matched component values and temperature coefficients. A frequency determining component of the sensing oscillator is formed integrally with the substrate and has an impedance parameter which varies with an environmental parameter to be measured by the sensor. A gating control is responsive to an output signal generated by the reference channel, for terminating counting in the at least one sensing channel at an output count, whereby the output count is indicative of the environmental parameter, and successive ones of the output counts are indicative of changes in the environmental parameter.

International Classification:

A61B 500

US Classification:

600561, 600300, 600486, 600587, 600128, 600903

Abstract:

The present invention relates to a completely implantable intracranial pressure monitor, which can couple to existing fluid shunting systems as well as other internal monitoring probes. The implant sensor produces an analog data signal which is then converted electronically to a digital pulse by generation of a spreading code signal and then transmitted to a location outside the patient by a radio-frequency transmitter to an external receiver. The implanted device can receive power from an internal source as well as an inductive external source. Remote control of the implant is also provided by a control receiver which passes commands from an external source to the implant system logic. Alarm parameters can be programmed into the device which are capable of producing an audible or visual alarm signal. The utility of the monitor can be greatly expanded by using multiple pressure sensors simultaneously or by combining sensors of various physiological types.

International Classification:

G01R 31/02

G01R 1/073

Abstract:

A system and method verifies continuity with and measures voltage across a circuit under test (in some instances simultaneously) using two or more test probes. Two or more probe continuity circuits measure continuity through the test probes by injecting a test current through and measuring a processed test current received at each of the plurality of test probes. The probe continuity circuits measure the respective processed test current rendered by the test current flowing through the test circuit at each test probe. A voltmeter measures the potential difference across the test probes.
