Abstract: 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.

Abstract: Methods, systems, and computer-readable media for generating a projected image are provided. Movement measurements are received from an accelerometer within a projection device. A determination is made as to whether the movement measurements indicate movement of the projection device. Upon determining that the movement measurements indicate movement of the projection device, a movement correction factor is determined based on the movement measurements to compensate for the movement of the projection device. The projection device is caused to generate a projected image according to the movement correction factor.

Abstract: In one or more embodiments of the disclosed technology, an Access Point (AP) schedules communication traffic flows or service tasks between an Access Point (AP) and one or more member stations in a Wireless Local Area Network (WLAN). The communication traffic flows or service tasks may include both control and management flows and data traffic flows. The communication traffic flows or service tasks may include traffic flows or streams of different types, each of which may have different service intervals. The order of service tasks can be changed from cycle to cycle, randomly, by rotation, or based on historical delay records.

Abstract: A set of cameras can operate in coordination for surveillance purposes to provide situation awareness at a system level. Any infrastructure of cameras, public or private, can incidentally view and record an individual's mobile property when in view of any of these cameras. A locating unit can determine the approximate location of a mobile property. A monitoring device that correlates to the mobile property's location can be selected. The transmission of surveillance information from the selected monitoring device can be provided to a user, such as via a transmission to the user's mobile device. Thus, the individual can have access to the monitoring device's viewing or recorded data to increase surveillance of mobile property.

Abstract: 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.

Abstract: The present method enables an RFID repeater to be used in conjunction with an RFID tag to allow data in the RFID tag to be read using wireless packet switched technologies. For example, the present method enables an RFID repeater to be coupled with an RFID tag. The RFID repeater reads and records the data from the RFID tag and then transmits the retrieved data from the RFID tag over a wireless packet network.

Abstract: 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.

Abstract: Methods, systems, and products measure health data related to a user. Often times a weight scale, blood pressure monitor, or other medical measurement device is shared among a group of users. A time-stamped physiological measurement is compared to a time-stamped message from a mobile device. If the timestamps are contemporaneous, then the physiological measurement is bound to the mobile device.

Abstract: Methods, systems, and products measure health data related to a user. A spoken phrase is received and time-stamped. The user is identified from the spoken phrase. A window of time is determined from a semantic content of the spoken phrase. A sensor measurement is received and time-stamped. A difference in time between the time-stamped spoken phrase and the time-stamped sensor measurement is determined and compared to the window of time. When the difference in time is within the window of time, then the sensor measurement is associated with the user.

Abstract: 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.

Abstract: The subject disclosure provides a system and method for wireless monitoring of sports activities. A subject participating in a sports activity is associated with biometric sensors which measure the subject's body movements. In one aspect, the system includes a sensor for continuously gathering biometric data from a subject performing a sports activity where the biometric data associated with the body movements of the subject. A wireless transceiver coupled to the sensor transmits the biometric data and a database engine receives the biometric data from the wireless transceiver and providing real-time feedback. The real-time feedback associated with the biometric data from the subject is characterized by instructions associated with the sports activity.

Abstract: A path configuration message is sent to nodes in a multi-hop network along a path between a source node and destination nodes. The path configuration message includes path information and one or more special channel access parameters associated with the path information. The path configuration message temporarily changes the channel access priority for packets matching the path information in the special message. The nodes along the path therefore have higher channel access priority relative to other nearby nodes and other traffic flows. At the end of the a length of a time determined by a time to live parameter in the special message, the nodes resume using default channel access parameters in place of the special channel access parameters for packets matching the path information.

Abstract: The disclosed subject matter relates to an architecture that can employ a control plane for managing communications with respect to a set of sensors. By utilizing a control plane, a distinction between control messages and data messages can be provided in a standardized way and the set of sensors can benefit from additional functionality and configurability. For example, the control plane can be employed to modify parameters associated with the set of sensors, which can be effectuated in real time and in situ as opposed to at the time of fabrication or deployment. Moreover, such modifications can relate to both the sensing portions of a particular sensor as well as the communication portions of a particular sensor.
