Title: Managing multiple cryptographic periods in a single cryptographic group
Inventor: KRUEGEL CHRIS A
IPC: H04L9/08
Filed: 2004-08-11
Granted: 2011-04-26
Abstract: A plurality of storage location numbers ("SLNs"), each having a cryptographic period, is received at a first device (100). A system cryptographic period is determined based on the SLN cryptographic periods. Prior to expiration of each system cryptographic period, if at least one SLN requires an updated, the first device sends updated key material for the at least one SLN. A second device (102) maintains first, second, and third keysets, wherein the first and second keysets comprise key material. The second device receives a message to make the first keyset active, and a second message for updating at least a portion of the key material in the second keyset with updated key material for at least one SLN. The second device makes the third keyset equivalent to the second keyset, updates the second keyset with the updated key material, and receives a third message to make the second keyset active.

Abstract: An anesthesia delivery device can be coupled to a ventilation system. The device includes an inspiratory gas line having a machine end and a patient end. The machine end can be fluidly coupled to the ventilation system, and the patient end can be received within the naris of the patient. A face mask having a dome portion can cover the patient's nose without covering the patient's mouth, and defines an inside air space between the patient's nose and the dome portion, and an outside air space exterior of the dome portion. A vent allows gas to pass between the inside and outside air spaces. An exhaust port can be fluidly coupled to the exhaust gas output. The exhaust port and vent can cooperatively exert a negative pressure on the outside air space for preventing inspiratory gas from entering the outside air space.

Title: Electric winding displacement detection method and apparatus
Inventor: MARTI JOSE R
IPC: G06F17/10
Filed: 2005-03-23
Granted: 2014-06-17
Abstract: A method and system for obtaining the characteristic impedance of an electrical winding by measuring the input and output voltages and the currents within a winding across a low frequency range, and applying transmission line properties to model the winding. The characteristic impedance (Zc) is directly proportional to the capacitance of the winding, and is independent of external circuits. Thus any changes to Zc will reflect movements of the winding that would affect the capacitance. Because Zc has a smooth and robust monotonical relationship with frequency of the applied signal, the resulting curve is exponential in shape. A relative comparison between Zc curves will provide a clear indication of the overall axial or radial winding movements, or winding faults, which can be used to assess the overall health of the winding.
