Inventor: SHRADER ERIC M
IPC: G06K9/00
Filed: 2002-08-12
Abstract: An approach for the compression of images such as fingerprints may involve a resolution reduction of an image before forming a cellular representation of the resulting resolution-reduced image. A given fingerprint image is divided into a number of finger pattern cells. Each finger pattern cell is then compared to each finger pattern cell in a set of predetermined finger pattern cells to find a close match. The set of closely matching predetermined finger pattern cells forms the cellular representation. The cellular representation may then be used as a basis for a finger pattern interchange data format for use with pattern-based fingerprint matching algorithms. The finger pattern interchange data comprises an identification of the predetermined finger pattern cells that most closely approximate the finger pattern cells that make up the fingerprint image.

Abstract: A pressure proving gas valve (10) insures safe and efficient operation of a fuel-burning appliance by monitoring combustion airflow and appropriately controlling the valve based (22) upon this airflow. An airflow sensor (26) is incorporated into a pressure proving valve housing (20) itself thus providing integrated solution for the control of the combustion process. Consequently, when heat is called for, no fuel is provided to the combustion chamber (12) unless appropriate combustion air is sensed. Further, by monitoring the actual airflow, additional control capability is provided. That is, a variable speed blower (60) associated with the combustion apparatus can be controlled to provide very precise fuel to air mixtures.

Title: Urocortin proteins and uses thereof
Inventor: VALE WYLIE W
IPC: C07K16/24
Filed: 2001-07-31
Abstract: A human urocortin-related peptide with significant sequence homology to the CRF neuropeptide family was identified. A mouse cDNA was isolated from whole brain poly (A+) RNA that encodes a predicted 38 amino acid peptide protein designated herein as urocortin II. Both human URP and mouse family members, CRF and urocortin (Ucn). These peptides are involved in the regulation of the hypothalamic-pituitary-adrenal axis under basal and stress conditions, suggesting a similar role for URP and Ucn II. Synthesized Ucn-II and URP  peptide binds with higher affinity to CRF-R2 than to CRF-R1 Ucn II and human URP appear to be involved in the regulation of body temperature and appetite and may play a role in other stress related phenomenon. These findings identify Ucn II and human URP as a new members of the CRF family of neuropeptides, which are expressed centrally and bind to CRF-R2.

Abstract: An apparatus for the controlled heating of a process fluid has a heater, a process fluid vessel containing the process fluid, and a bundle of thermosyphons extending between a burner chamber of the heater and the process fluid inside the vessel for transferring heat from the heater to the process fluid. Burners in the burner chamber are controlled to maintain the bulk temperature of the process fluid T BULK substantially within an operating range defined by preset upper T HIGH  and lower T LOW temperature setpoints. The burners can be turned on to maintain an outside metal temperature T EVAP of the evaporator ends of the thermosyphons above a preset dew point temperature T DEW to prevent corrosion. The burners can also be shut down if an outside surface temperature T OD of at least one of the condenser ends of the thermosyphons extending into the vessel exceeds a predetermined setpoint temperature T ALARM. Different configurations of condenser ends of the thermosyphons in the vessel may be utilized to enhance heating the process fluid.     The vessel and heater are separated and sealed from each other by a sealed chamber encasing the thermosyphons, which may also be used to preheat incoming combustion air for the burners.

Inventor: DAMIANI PHILIP
IPC: C12N15/85
Filed: 2001-10-05
Abstract: The present invention concerns the use of chromosomal replacement techniques in the context of producing cloned and transgenic animals, in order to correct chromosome abnormalities or alter autosomal genotypes, and provide for novel breeding pairs by replacing the sex chromosome in animals to be cloned.  Replacement of a sex chromosome, or an X or Y chromosome, will result in animals that are autosomally isogenic and sexually non-isogenic (AISN), with "autosomally isogenic" meaning that the paired sets of autosomes (non-sex chromosomes) in each animal are isogenic or identical. Also included in the invention are animals that are both "autosomally" and "allelically" isogenic whereby each particular pair of chromosomes is internally isogenic or identical within a single animal as well as between animals. Such animals are particularly useful in generating a line of cloned mammals using sexual reproduction, without having the undergo nuclear transfer in order to propagate cloned animals.
