Appl. No.:

09/344990

Inventors:

Wayne L. Brinster - Kinnelon NJ
Stephen C. Wardlaw - Lyme CT
Robert A. Levine - Guilford CT

Assignee:

Becton Dickinson and Company - Franklin Lakes NJ

International Classification:

G01N 2100

US Classification:

422 58, 422 73, 422 99, 422102, 436 69, 436 70, 436174, 436177

Abstract:

An improved system can be used to examine a centrifuged sample of anticoagulated whole blood for evidence of blood borne rare events such as: circulating cancer cells; malarial parasites; other hemato-parasites; bacteria; and the like; and can also be used in the measurement of hematocrit and hemoglobin, as well as white cell and platelet count values in the centrifuged blood sample. The system includes a transparent blood sample tube and an insert that is placed in the tube. The insert floats on the packed erythrocyte layer in the centrifuged blood sample, and expands all of the layers above the packed erythrocyte layer. The insert also forces any blood borne rare events to the periphery of the blood sample in the tube where such events can be detected through the tube wall. The bottom end of the tube is closed by a closure which includes an outer sheath and an inner plug that projects up into the tube bore to a degree necessary to elevate at least the upper portion of the packed erythrocyte layer into which the insert has settled sufficiently so as to be detectable above the cap, and preferably examinable microscopically after the blood sample has been centrifuged. The outer sheath of the tube closure includes an outer annular surface which is provided with sensible indicia.

International Classification:

A61B 514

US Classification:

128771

Abstract:

A centrifuge tube is used to hold a mixture of several constituents, and also contains a generally cylindrical float. The float settles, after centrifugation, into the zone occupied by the constituent whose volume is to be measured. The constituent layer will settle, after centrifugation, into the annular space between the tube bore and the outside of the float, and will be expanded axially due to the restricted volume of the annular space. The degree of expansion is dependent upon the respective sizes of the float O. D. and the tube bore ID, both of which must be closely controlled for accurate results. A known volume of a control material is placed in the tube to settle into the annular space during centrifugation in an area thereof outside of the constituent layer zone. The length of the band of the control material is measured after centrifugation and is compared to a known length which will result if the annular space is of the proper target volume. A correction factor is thus obtained and applied to all of the other constituent layers which were measured.

International Classification:

H04L 29/06
H04L 9/08

Abstract:

A method for leveraging a first secure channel of communication between a first agent and a second agent to create a second secure channel of communication between the first agent and a third agent. The method includes creating the first secure channel of communication between the first agent and the second agent using a configurable data-driven initial process on a first computing device. Responsive to the first agent receiving a request from the third agent to establish the second secure channel of communication, the method further includes retrieving identifying information from the third agent. The method further includes ending the identifying information from the third agent to the second agent over the first secure channel of communication. Responsive to receiving approval of the third agent's request from the second agent, the method further includes establishing the second secure channel of communication.

International Classification:

H04L 29/06
H04L 9/08

Abstract:

An apparatus includes a computing system that is configured to receive, from an electronic device, a verification message indicating that the electronic device is not corrupt. The computing system is also configured to receive, from the electronic device, a unique universal identifier (UUID) that is associated with an application stored in a memory of the electronic device. The computing system is further configured to receive, from a management server of the one or more management servers, a server key stored in a credential store and that is associated with the UUID received from the electronic device. In addition, the computing system is configured to establish one or more secure channels for electronic data communication with the electronic device based on the received UUID and the server key.

Abstract:

A method for leveraging a secure communication channel between a first agent and a second agent to authenticate an activity outside of the secure communication channel. The method includes receiving with the first agent a communication request through an insecure channel from the second agent. The method further includes receiving with the first agent an indicator of a relative identity relationship from the second agent. The method further includes sending with the first agent a request to authenticate the activity outside of the secure communication channel to the second agent. The method further includes authenticating the activity outside of the secure communication channel using the secure communication channel.
