Appl. No.:

08/884714

Inventors:

Ark L. Lew - Ellicott City MD
Joseph J. Suter - Clarksville MD
Binh Q. Le - Vienna VA

Assignee:

The Johns Hopkins University - Baltimore MD

International Classification:

H07J 700

US Classification:

320107, 320101, 320108

Abstract:

A self-contained, small, lightweight, portable, renewable, modular integrated power source. The power source consists of a recharging means such as solar cells that are laminated onto a rechargeable energy source such as a solid state polymer battery which in turn is laminated onto a substrate containing circuits which manage the polymer battery charging. Charging of the battery can occur via solar energy or, alternatively, via RF coupling using external RF charging equipment or a hand held generator. For added support, the integrated power source is then bonded to an applications housing or structure. This integrated power source can independently power the electronic application. It can also serve as casing or housing by taking the shape of the application enclosure.

Abstract:

An ambulatory skin temperature monitoring system. A flexible band is attachable to a patient. The flexible band also secures an electronics assembly that comprises the various electrical components that monitor and operate the ambulatory skin temperature monitoring system. At least one skin temperature sensor is positioned so that it is in contact with the patients skin when the system is attached to the patient. There is also an ambient temperature sensor positioned on the top surface of the electronics assembly housing for measuring and contrasting the ambient temperature to the skin temperature. The electronics assembly positioned within generally comprises a power source and a micro-controller. The micro-controller is coupled with the skin temperature sensor and the ambient temperature sensor. The micro-controller also includes a memory unit for storing temperature data obtained from the skin temperature sensor and the ambient temperature sensor.

International Classification:

US Classification:

436106, 436107, 436110, 436111, 436156, 436172

Abstract:

An explosive detector that utilizes an array of molecularly imprinted polymer (MIP) coated, bifurcated fiber optic cables to form an image of a target molecule source. Individual sensor fiber assemblies, each with a calibrated airflow, are used to expose the fibers to the target molecule. The detector energizes a dedicated excitation light source for each fiber, while simultaneously reading and processing the intensity of the resulting fluorescence that is indicative of the concentration of the target molecule. Processing electronics precisely controls the excitation current, and measures the detected signal from each narrow band pass filter and photodiode. A computer with display processes the data to form an image of the target molecule source that can be used to identify the source even when low level contamination of the same molecule is present. The detector can be used to detect multiple and/or non-explosive targets by varying the MIP coating.

International Classification:

G06F017/60

US Classification:

705/010000

Abstract:

A real-time feedback survey system and method allowing for responses to survey questions to be input by users and received by the surveyor in real-time is provided. This result is achieved by using a media player to provide a request for feedback information to a remote responding device, the remote responding device allowing response input and incorporating a transmitter for transmitting the response to a central facility.

International Classification:

C10G 2900

US Classification:

208207

Abstract:

An improved method of treating streams having mercaptan or mercaptan-based compounds therein particularly adapted for the processes of sweetening sour hydrocarbons and regenerating spent caustic solutions is described. The invention comprises contacting a first stream having the mercaptan or mercaptan-based compounds therein with a second stream in the presence of effective amounts of a nitrogen-based promoter to promote the extraction and/or the catalytic oxidation of the mercaptan compounds therein. The invention herein disclosed and described is applicable in a wide variety of apparatus and processes adapted for sweetening and regeneration operations.
