Granted: 1994-03-22
Abstract: Abstract of the Disclosure A method and an apparatus for generating a plurality of parameters of an object in a field of view is disclosed.  An electrical image of the field of view is formed.  The electrical image is processed to form a plurality of different representations of the electrical image where each different representation is a representation of a different parameter of the field of view.  The positional information, which represents the boundary of the object, is generated.  In response to the positional information that represents the boundary of the object being generated, corresponding locations in each of the different representations is traced.  The different parameters from each of the different representations are calculated as the locations are traced in each of the different representations.

Granted: 1992-05-26
Abstract: Abstract of the Disclosure This invention provides a nozzle for discharging a relatively small amount of a metals passivating agent into a catalytic cracking unit at a  relatively high velocity through a relatively large diameter opening.  This invention further provides a process for discharging a relatively small amount of a metals passivating agent into a high-temperature zone of a catalytic cracking unit, wherein the temperature range of the high-temperature zone exceeds the melting point of the particular passivating agent,  through the utilization of a metals passivating agent injection nozzle which disperses the passivating agent, prior to discharging the agent into a catalytic cracking system, and accelerates this  dispersed metals passivating agent to a maximum discharge velocity by injecting a dispersing agent into the novel nozzle at a location behind that at which the passivating agent is injected, and then discharging the dispersed metals passivating agent at a relatively high velocity through a passage having a relatively large inside diameter.

Title: Personal identification number processing using control vectors

Granted: 1993-02-02
Abstract: PERSONAL IDENTIFICATION NUMBER PROCESSING                  USING CONTROL VECTORS                        ABSTRACT    Cryptographic  PIN  processing  is  achieved  in  an improved manner by associating control vectors with the PIN generating (verification) keys and PIN encrypting keys which provide  authorization for the uses of  the keys intended by the originator of the keys.   The originator may be the local cryptographic facility (CF) and a utility program under the control of a security administrator, or the originator may be another network node.   Among the uses specified by the control vector are limitations on the authority to use the associated key with certain PIN processing   instructions,   such   as   PIN   generation, verification,   translation  and  PIN  block  creation.          Furthermore, the control vector may limit the authority of certain instructions to process clear PIN inputs (such as in PIN verification).  The control vector may contain information identifying and,  possibly restricting,  PIN processing  to  a  particular  PIN  format  or  particular processing algorithm.  The control vector implementation provides a flexible method for coupling format, usage, and processing   authorization   to   keys.      The   system administrator can exercise flexibility in changing the implementation  of  his  security  policy  by  selecting appropriate  control  vectors  in  accordance  with  the invention.   Furthermore,  a method is provided for the security administrator to  restrict certain PIN format translations.

Title: System for use with solid state dosimeters
Inventor: MILLER STEVEN D
IPC: G01T1/11
Filed: 1989-05-29
Granted: 1992-10-27
Abstract: ABSTRACT OF THE DISCLOSURE          The  present  invention  constitutes  a  system  for determining  the  amounts  of  ionizing  radiation  to  which dosimeters  using  thermoluminescent  materials  have  been exposed.      In   accordance   with   this   system,   the thermoluminescent materials which comprise the dosimeters are first cooled by contact with a cryogenic substance such as liquified nitrogen.  The thermoluminescent materials are then optically  stimulated  by  exposure  to  ultraviolet  light. Thereafter,  the amounts of visible light emitted by the thermoluminescent materials are detected and counted as the materials are allowed to warm up to room temperature.  The amounts  of  luminescence  exhibited  by  the  materials  are related to radiation exposure and provide a sensitive measure of radiation dosage.  It has been discovered that the above procedure   is   most   effective   when   heavily   doped thermoluminescent materials are used and that the procedure allows many useful plastic materials to now be employed in dosimeter constructions.

For any of those three embodiments, a substantially flat arrangement results, with advantages associated therewith.  Preferred arrangements having a field of conductive adhesive, associated with the pad portion of the conductor member, completely surrounded by a border of insulator construction and skin adhesive, are described.

Abstract: A percussive mole boring device with a location transmitter is disclosed. The transmitter is located in a forward end of a drilling assembly attached to a mole to accurately transmit the location of a boring element or cutting surface to surface detector. The transmit-ter is surrounded on each end by isolator means which protect the transmitter from damage due to shock created by the percussive device, e.g, a hammer driven by compressed air. In one embodiment the transmitter is located beneath a single window transparent to the transmission frequency, and the cutting surface of the bore is angled. Therefore, the travel direction of the mole can be controlled by rotat-ing the cutting surface to a desired inclination and terminating rota-tion during forward motion for a short period. The mole travels in a straight path during ordinary travel due to rotation. In a second embodiment, the transmitter is located beneath three equiangularly displacent windows to create a continuous field for detection. This type of mole is not steerable and includes a boring element with a non-angled edge. In a third embodiment which is similar to the sec-ond embodiment, the windows are not present, and a transmitter coil is wound in an external groove of the drilling assembly and is covered by epoxy.
