20110125000 | METHOD AND COMPUTER PROGRAM FOR AUTHENTICATING A PHYSIOLOGICAL SENSOR, A SENSOR SYSTEM, A PATIENT MONITOR, AND A PHYSIOLOGICAL SENSOR - A mechanism for authenticating a physiological sensor is disclosed. When a sensor is connected to a monitor, the monitor examines whether a first sensor-specific usage identifier of the connected sensor is consistent with a second sensor-specific usage identifier thereof. The first and second sensor-specific usage identifiers are indicative of the cumulative usage of the connected sensor, but may nevertheless be unequal. The first sensor-specific usage identifier is maintained in the sensor and the second sensor-specific usage identifier in a host memory external to the sensor. The use of the connected sensor is allowed when the examining indicates that the said two identifiers of the connected sensor are consistent, and rejected when the identifiers are inconsistent. The two identifiers are further updated in response to the use of the connected sensor in the patient monitor, thereby to keep the said identifiers consistent and updated for a subsequent use attempt of the sensor. | 05-26-2011 |

20110141966 | DATA-RELATED TASK SUPPORT IN WIRELESS COMMUNICATION SYSTEMS - Apparatuses may stay synchronized with a network via a beacon signal that is transmitted at a set interval. Various communication-related activities may be planned around an instance when a beacon signal is expected, or a target beacon transmission time (TBTT).

Awareness may comprise information related to communication configuration, apparatus status, and services offered by the various apparatuses in the network. Awareness information obtained during an awake window may also comprise information on data-related tasks that are pending in one or more apparatuses which may allow for the control of further data conveyance activities. | 06-16-2011 |

In example scenarios where apparatuses opt to utilize scanning opportunities, apparatuses may prepare a network information message and then enter a passive scanning mode. Apparatuses may remain in the passive scanning mode for the duration of the scanning opportunity, reacting when messages are received from devices outside of the network by transmitting the network information message. | 06-16-2011 |
20110142028 | SYNCHRONIZATION VIA ADDITIONAL BEACON TRANSMISSION - Apparatuses may stay synchronized with a wireless network utilizing a diluted beacon interval that is an integer multiple of a network beacon period signal being transmitted at a set interval.

Apparatuses may be active in the network during an awake window wherein a beacon may be transmitted. A set time may also be set during the awake window may delineate a period of time after which any beacon signal received from another apparatus is deemed to be late. Receiving late beacon signals in the apparatus may trigger the transmission of additional beacon signals to help the other apparatuses that transmitted late beacons become resynchronized with the network. | 06-16-2011 |
20110142029 | NETWORKING IN WIRELESS COMMUNICATION SYSTEMS - A system where apparatuses may stay synchronized with a network utilizing a reduced beacon period based on an integer multiple of a standard beacon period that is established for the network.

Network information messages may comprise connectivity information that would be usable by outside apparatuses to determine whether participation in the network described in the network information message (e.g., another network) is desired. If the apparatus desires to interact with apparatuses in the other network, then further decisions may be made with respect to how communication between these entities should be established. | 06-16-2011 |
