Nuclear Measuring Gauge With Automatic Detection Of Source Depth
US Patent:
4749858, Jun 7, 1988
Filed:
Aug 27, 1986
Appl. No.:
6/900981
Inventors:
James E. Young - Youngsville NC
Assignee:
Troxler Electronic Laboratories, Inc. - Research Triangle Park NC
International Classification:
G21G 406, G01V 500
US Classification:
250253
Abstract:
The present invention provides an apparatus for detecting the depth position of the source rod of a portable nuclear measuring gauge having a housing with the elongate source rod extending vertically therethrough and mounted for vertical sliding movement to various depth positions. The apparatus comprises an elongate variable resistance element extending axially parallel to said source rod, means for slideably engaging the elongate variable resistance element as the source rod is moved to various depth positions so as to vary the resistance of said variable resistance element, and means electrically connected to said variable resistance element for sensing the changes in resistance thereof and converting such changes into an indication of the depth position of the source rod.
Apparatus And Method For Indicating Remaining Battery Life In A Battery Powered Device
US Patent:
4743831, May 10, 1988
Filed:
Sep 12, 1986
Appl. No.:
6/906543
Inventors:
James E. Young - Youngsville NC
Assignee:
Troxler Electronic Laboratories, Inc. - Research Triangle Park NC
International Classification:
H02J 700, G08B 2100
US Classification:
320 48
Abstract:
The remaining battery life of a battery powered device is predicted by monitoring the immediate past history of battery life and employing this immediate past history as a basis for subsequent predictions of the useful life of the battery. By this approach, the present invention is able to take into account the deterioration of battery life which occurs during the life-time of a rechargeable battery. The device includes a data storage means for storing a predetermined value representing the total number of usable hours to be expected to obtain from a fully charged battery during normal use, means for counting the number of hours of actual use of the battery, and means operable in response to the occurrence of a full discharge of the battery in normal use for updating the data storage means to store therein as the predetermined value for the expected useful life of the battery in the next cycle of normal use, the value for the number of hours of use actually obtained from the battery in the current cycle, so that subsequent predictions of the battery life will be based upon the immediate past history of actual battery life.
