A material medium, such as an optical fiber or electrical cable, is used to carry services. The material medium is monitored with at least one diagnostic sensor. The diagnostic sensor may measure the operational health of the material medium, or may measure local environmental conditions around the material medium.

Method and apparatus for monitoring a material medium

Methods, systems, and products measure health data related to a user. A time-stamped device identifier is received that uniquely identifies a communications device. A time-stamped sensor measurement is separately received. A difference in time between the time-stamped device identifier and the time-stamped sensor measurement is determined. When the difference in time is within a window of time, then the sensor measurement is associated with the device identifier.

Remote monitoring of physiological data via the internet

A method includes transmitting a first message during a first time interval of a frame from a device. Transmission of the first message is followed by a second time interval of the frame. The method further includes transmitting a second message during the second time interval. The second message is followed by a third time interval that is shorter than the second time interval. The third time interval includes a contention-free period, a contention period, or a combination thereof.

Devices, systems, and/or methods for managing wireless networks

A system that incorporates teachings of the present disclosure may include, for example, includes a broadband signal access point, which may be located internally or externally to the premises, in combination with the existing cabling is used with radiation device(s) to provide distribution of services, including broadband services, within the premises. Additional embodiments are disclosed.

Intra-premises wireless broadband service using lumped and distributed wireless radiation from cable source input

Methods, systems, and products for measuring health

A method includes receiving a beacon message at a wireless network device. The beacon message is followed by a beacon time interval. The method further includes receiving a thin beacon message during the beacon time interval. The thin beacon message is followed by a thin beacon time interval that is shorter than the beacon time interval. The thin beacon time interval includes a contention-free period, a contention period, or a combination thereof.

A security device for detecting the position of a manhole cover includes a pinger device, such as an acoustic pinger, that transmits a signal in the direction of the expected position of the manhole cover. The device takes energy samples to determine if the signal has been reflected back by the manhole cover. If the device determines the signal has not been reflected, it determines that the manhole cover has been moved from the expected position. In response, the device captures an image of an area around the expected position of the manhole cover. In addition, the device can notify a remote security station via a network that the manhole cover has been moved.

Manhole security device and methods thereof

In a wireless local area network, a first and second access point in which the RF coverage areas overlap are synchronized by positioning a monitor station within the overlap area. The monitor station receives beacon frames from both access points and records the arrival times. A manager in communication with both access points and the monitor station calculates a retardation interval and issues a control command to the second access point to retard transmission of its beacon frame. The retardation interval is calculated such that the contention-free period of the second access point does not overlap the contention-free period of the first access point. The manager may also issue control commands to the first and second access points to adjust their contention-free periods.

Synchronizing wireless local area network access points

Methods, systems, and products measure health data related to a user. A time-stamped device identifier is received that uniquely identifies a communications device. A time-stamped sensor measurement is separately-received. A difference in time between the time-stamped device identifier and the time-stamped sensor measurement is determined. When the difference in time is within a window of time, then the sensor measurement is associated with the device identifier.

The RF signal generated by a ZigBee radio on the outside of a building structure is conveyed to the interior of the building by guiding it along an electric cable bundle that passes through the building's wall to supply domestic electric power to the interior of the structure. The RF signal is launched by a unique coupler comprising a pair of insulated foil conductors.

Technique for conveying a wireless-standard signal through a barrier

Certain exemplary embodiments comprise a method that can comprise wirelessly transmitting a thin Beacon message from an Access Point in a wireless local area network cell. The thin Beacon message can be transmitted during a superframe subsequent to a Beacon message. The thin Beacon message can be transmitted at a predetermined thin Beacon time interval. The time period between consecutive Beacon and/or thin Beacon messages can be divided further into a thin CFP and a thin CP.
