Abstract:

A telephone system for providing a telephony feature includes a phone system controller and a first telephone system interface. The first telephone system interface is coupled between a first telephone handset and a telephone line. Moreover, the first telephone system interface is operable to selectively couple the first telephone handset to the telephone line. The first telephone system interface is also operable to establish a first wireless control channel to the phone system controller. The wireless control channel is operable to carry control signals associated with the telephony feature between the first telephone system interface and the phone system controller. The phone system controller is operable to (i) receive the first control signals via the wireless control channel, and (ii) process the first control signals to provide the telephony feature to the telephone handset.

International Classification:

H04L 9/00

US Classification:

380277, 380278

Abstract:

A control method, apparatus, and system capable of securely distributing a shared secret network encryption key from a host to a wireless peripheral device. The sharing of the secret network encryption key is accomplished without the intervention of a man-machine interface at the peripheral. Embodiments enable a wireless device to receive and store multiple encryption keys, to select the appropriate encryption key depending on the network in range of the device, and thus to freely associate with multiple networks.

Assignee:

Covidien LP - Mansfield MA

International Classification:

A61B 5/00

US Classification:

600424, 12820026, 12820714

Abstract:

According to various embodiments, a sensor may be placed on a patient chest adjacent to a desired position of a distal end of a tracheal tube. The sensor may be configured to emit an electromagnetic field into the patient and detect perturbations to that field caused by the presence of the tracheal tube. As the tube is inserted within the trachea, the sensor may detect the tube when the distal end passes within range of the sensor, indicating that a proper insertion depth has been reached. In certain embodiments, multiple sensors may be placed along the chest adjacent to the trachea to determine a distance between the tube and an anatomical structure. The distance information may provide an indication as to whether the tracheal tube is properly placed within the trachea.

Appl. No.:

12/880306

Inventors:

Edward M. McKenna - Boulder CO, US
Daniel Jon Peters - Longmont CO, US

Assignee:

Nellcor Puritan Bennett LLC - Boulder CO

International Classification:

A61B 5/145

US Classification:

600364, 600300

Abstract:

Methods and systems are provided for using time-frequency warping to analyze a physiological signal. One embodiment includes applying a warping operator to the physiological signal based on the energy density of the signal. The warped physiological signal may be analyzed to determine whether non-physiological signal components are present. Further, the same warping operator may be applied to signal quality indicators, and the warped physiological signal may be analyzed based on the warped signal quality indicators. Non-physiological signal components, or types of non-physiological noise sources, may be identified based on a comparison of the physiological signal with the signal quality indicators. Non-physiological signal components may also be identified based on a neural network of known noise functions. In some embodiments, the non-physiological signal components may be removed to increase accuracy in estimating physiological parameters.

Abstract:

Present embodiments relate to systems, methods, and devices for decomposing a physiological signal of a patient using empirical mode decomposition (EMD). In one embodiment, the EMD algorithm may involve identifying a frequency component, referred to as an intrinsic mode function, in the physiological signal. The physiological signal may be decomposed into one or more intrinsic mode functions through multiple iterations of the EMD algorithm. Each subsequent mode function may have a different frequency component of the original physiological signal input into the EMD algorithm. In some embodiments, each mode function may be further analyzed and/or processed to determine various physiological data corresponding to blood flow in the patient.

Inventors:

Daniel J. Peters - Longmont CO, US

Assignee:

Nellcor Puritan Bennett LLC - Boulder CO

International Classification:

A61B 5/00

US Classification:

600301

Abstract:

Systems and methods are provided for patient monitors which apply phase detection operations to analog signals to identify differential pulse transit time (DPTT). Photoplethysmograph (PPG) signals measured at two sensor sites may be processed by a phase detection system to identify phase information that allows the calculation of a DPTT. The phase detection system may process analog PPG signals in the analog domain to determine phase information. In some embodiments, the phase detection system may process optical oximetry sensor signals to determine phase information using, for example, interferometric methods.
