International Classification:

A61B 5/00

US Classification:

600309, 600310, 600322

Abstract:

A system and method for extracting a biological fluid from an organism and continuously monitoring its characteristics. The system includes a tissue interface device suitable for positioning on or about the surface of the biological membrane of the organism and a monitor and control unit coupled to the tissue interface device. The tissue interface device includes a sensor positioned in a flow path of the fluid for continuously sensing a characteristic of the biological fluid as it flows out from the one or more artificial openings formed in the biological membrane. The sensor generates a sensor signal representative thereof. The monitor and control unit electrically or optically reads the sensor to obtain a measurement of a characteristic, such as concentration of a particular analyte, of the biological fluid on a continuous basis.

Gregory Newman - Fremont CA, US

International Classification:

G01N021/47

US Classification:

356/446000

Abstract:

A system and method for measurement and analysis of a sample by absorption spectrophotometry is taught by the present invention. According to various embodiments, the invention utilizes a novel receptacle comprising of at plurality of layers including a transparent layer, a channel layer, and a reflective layer coupled to one another and allowing for fluid communication within and among the layers to allow for illumination by a light source and interrogation and analysis by a light measuring device. Examples of the light source and light measuring devices that could be used with the present invention include reflectance and/or fluorescence spectroscopy and a spectrometer, respectively. Measurement and analysis of a sample is compared to known values of constituents for comparison.

Appl. No.:

9/373734

Inventors:

Mark A. Samuels - Norcross GA

International Classification:

A61B 500

US Classification:

600500

Abstract:

A heart beat cycle indicating device for indicating to a firearm operator a defined stage of the heart beat cycle of the firearm operator includes a heart beat cycle monitoring unit for monitoring the heart beat cycle of the firearm operator and a heart beat cycle indicating unit for indicating to the firearm operator a specific stage of the heart beat cycle. A heart beat cycle override unit may be used in combination with the heart beat cycle indicating device to prevent discharge of a firearm during a specified stage of the heart beat cycle of the firearm operator. An automatic firing assembly for automatically firing a firearm when the firearm is aligned with a target comprises a target detection unit in combination with a trigger actuation unit for actuating a firearm trigger. Methods for making a heart beat cycle indicating device and an automatic firing assembly are disclosed, together with methods for operating a firearm in combination with a heart beat cycle indicating device or an automatic firing assembly.

International Classification:

G01B 902

US Classification:

356351

Abstract:

A combined infection shield and calibration or reference target for use with a measuring instrument includes a removable calibration/reference layer. The removable calibration/reference layer has predetermined optical characteristics that can be utilized to calibrate or reference the instrument. The calibration/reference layer may have predetermined reflectance or scattering properties, a predetermined transmissivity to light, or it may have predetermined fluorescence properties. When the calibration/reference layer is removed from the remaining portions of the device, the portion of the calibration/reference layer having the predetermined optical characteristics is irrevocably altered such that the calibration/reference layer cannot be reused. The combined infection shield and target may be attached to a shield holder, which in turn is attached to an instrument. Alternatively, the infection shield and target may be attached directly to an instrument.
