6402031, Jun 11, 2002

Filed:

Dec 16, 1997

Appl. No.:

08/997188

Inventors:

Donald R Hall - Arlington VA 22201

International Classification:

G06F 1900

US Classification:

235400

Abstract:

A weather resistant modular sensor and computing platform reduces costs and enhances versatility of sensor systems. Rapidly evolving electronic technology results in hyper-obsolescence wherein sensor systems that are state of the art technology when designed, fall behind the art quickly as new transducers, batteries and components are developed. A cylindrical shaped modular system provides an architecture for up-grading sensors, batteries, special modules, communications, and control. A modular architecture extends the life cycle of a system and avoids hyper-obsolescence and the requirement to design a complete new system to incorporate new technology. Modularity and low cost manufacturing methods enable the practical definition of a cylindrical computer. The cylinder shaped enclosures have on their ends a common connection interface to which modules may be added. This provides a long system life cycle and wide ranging versatility.

Appl. No.:

09/991139

Inventors:

Donald R. Hall - Arlington VA 22201

International Classification:

A01M 100

US Classification:

43107, 431321

Abstract:

An apparatus configured to provide standing water at convenient locations for the use of mosquitoes to lay eggs. After eggs are deposited in the development cycle of the egg, the larva, pupa, adult life stage are interrupted by denying the proper environment to sustain their development. Also disclosed is an apparatus to abate mosquito populations which provides a convenient and attractive reservoir of liquid situated to encourage use by mosquitoes for egg laying. At intervals the liquid in the reservoir is flushed or filtered eliminating mosquito biomass developing in the liquid. The bio-matter is substantially removed and aborts the development of the bio-matter into adult insects.

Abstract:

A weather resistant modular sensor and computing platform reduces costs and enhances versatility of sensor systems. Rapidly evolving electronic technology results in hyper-obsolescence wherein sensor systems that are state of the art technology when designed, fall behind the art quickly as new transducers, batteries and components are developed. A cylindrical shaped modular system provides an architecture for up-grading sensors, batteries, special modules, communications, and control. A modular architecture extends the life cycle of a system and avoids hyper-obsolescence and the requirement to design a complete new system to incorporate new technology. Modularity and low cost manufacturing methods enable the practical definition of a cylindrical computer. The cylinder shaped enclosures have on their ends a common connection interface to which modules may be added. This provides a long system life cycle and wide ranging versatility.

Appl. No.:

6/408225

Inventors:

Donald C. Hall - Westminster CA

International Classification:

A61H 102

US Classification:

128 75

Abstract:

Portable cervical traction apparatus including a generally planar generally rigid platform of radiolucent material attachable to a turning frame for use with the conventional traction arrangement thereof, and a portable traction unit attachable to the platform without interfering with the conventional traction. The unit has a framework configured for straddling the conventional traction cord while attaching the unit to the platform in the space between the patient's head and the adjacent end of the platform. The weight carrying assembly is movably mounted in the lower part of the unit and includes a split weight carrying plate arrangement for straddling the cord. A compound pulley arrangement enables the applying of tension to the cord of the unit with one end attached to the traction bracket and the other end fixed relative to the framework, after which the conventional traction can be removed and the patient transported on the platform, in traction, for further diagnosis or treatment, the size of the unit being compact for enabling passage through the opening of computerized tomography apparatus.

Abstract:

A data processing security device, attached to computing equipment, inserts labels into a data stream that indicate security controls for the data. The security device may also be configured to detect security labels within a data stream and inhibit the flow of data. It also may replace data within a data stream if it detects labeled fields which indicate that privacy should be imposed.
