US Patent:

55875815, Dec 24, 1996

Filed:

Jul 31, 1995

Appl. No.:

8/509382

Inventors:

Peter C. Stroosnyder - Finksburg MD

Assignee:

Environmental Technologies Group, Inc. - Baltimore MD

International Classification:

B01D 5944
H01J 4900

US Classification:

250287

Abstract:

In an apparatus for an air sample analysis, employing a dual polarity Ion Mobility Spectrometer (IMS), a method for stabilizing equilibrium conditions associated with the switching of the electric fields in the IMS cell comprises the steps of modulating a duty cycle of the electric field at the shutter grid located between the reactor region and the drift region of the IMS cell. During the switching of the electric fields at the cell, the open time of the duty cycle of the electric field at the shutter grid is extended. After the background polarity has been switched to the opposite polarity, the open time is returned to its normal value.

US Classification:

250288

Abstract:

In an apparatus for detecting alarm molecules, residual alarm molecules are automatically removed during a clear-down mode before a subsequent air sample is to be introduced. The apparatus comprises a detector unit, a sensor unit and a filtering sub-unit including a pump and a filter. During a challenge, the pump in the sub-unit is turned off, and the air sample passes from the inlet port of the first unit through the second unit to the output port of the first unit, thereby depositing alarm molecules in the first unit and the second unit. During the clear-down mode, the pump in the sub-unit is turned on, and outside air enters through the output port of the first unit, mixes with air flow from the output of the second unit, and passes through the sub-unit. Filtered air from the sub-unit exhausts the first unit through the inlet port of the first unit and passes into the second unit, thereby cleaning the first unit and the second unit from the alarm molecules deposited therein during the challenge mode.

International Classification:

A63B 69/36

Abstract:

Disclosed is a golf putter incorporating a training device that is configured to provide an intuitive coaching system to aid a golfer in the development of proper visualization of their putt, and that provides a configuration that ensures that the golfer maintain proper form (including through ensuring proper alignment, proper backswing, and proper topspin application) throughout their practice putting strokes. The golf putter includes a motion sensor that determines and preferably displays to the golfer the speed of their putting stroke and the distance of that stroke through both rearward (backstroke) and forward (throughstroke) movements, and provides a light beam projection device configured to project a tracking pathway onto the ground in front of the putter, indicating the ball path that the putter should strive to putt the ball through with their stroke while insuring proper alignment of the putter face with the intended target line. Such configuration is designed to allow the golfer to develop constant distance feel and putter face alignment during practice sessions and on to the golf course.
