Techniques for operating a sensor are provided. An example method according to these techniques includes sensing, at the sensor, changes in intensity of a magnetic field of a magnet affixed to a monitored asset to produce sensor data, wherein the monitored asset is disposed in a non-metallic liquid or solid medium, and wherein the sensor is disposed outside of the non-metallic medium; The method also includes analyzing, at the sensor, the sensor data to produce feature information indicative of vibration of the monitored asset. The method also includes providing the feature information to a predictive algorithm to generate prognosis information indicating an occurrence of a known condition of the monitored asset.

Remote vibration detection of submerged equipment using magnetic field sensing

Techniques for operating a remote monitoring system are provided. An example method according to these techniques includes sensing one or more characteristics associated with a monitored asset to produce sensor data, and dynamically configuring operating parameters of the monitoring system based at least in part on current operating conditions of the monitoring system. The example method also includes extracting features from the sensor data using the feature extraction component to produce extracted feature information, and selecting at least a subset of the extracted feature information using the feature extraction component to produce active feature information based at least in part on the current operating conditions of the monitoring system. The example method also includes sending, through a communications network, the active feature information to a server.

Certain aspects of the present disclosure relate to a method for forwarding of data in peer-to-peer transactions by a high-capability wireless device, such as an access point.

Method for forwarding in peer-to-peer wireless communications

Certain aspects of the present disclosure provide techniques and apparatus for operating in a television white space (TVWS) network. One example method generally includes receiving, at an apparatus, a message with a field indicating a current version of an unused frequency spectrum map (e.g., a white space map (WSM)), the unused frequency spectrum map indicating channels usable for wireless communications; determining whether the current version of the unused frequency spectrum map is different than a previous version of the unused frequency spectrum map; and using a channel for wireless communications based on the determination. Another example method generally includes accessing a database of available channels for a current location of an apparatus via a neighboring portable or fixed enabling apparatus and enabling one or more portable dependent apparatuses for the wireless communications via one or more of the available channels.

Protocols for enabling mode 1 and mode 2 devices in TV white space networks

Systems and methods for controlling a data rate of a transmission in a wireless communication system during handoff are described herein. In some embodiments, controlling the data rate includes receiving transmissions from a plurality of base stations, wherein each received transmission includes a data rate control indicator, and adjusting the data rate of the transmission during handoff based on the data rate control indicators from the plurality of base stations.

A method and apparatus for controlling a data rate of a transmission in a wireless communication system during handoff. Controlling the data rate includes receiving transmissions from a plurality of base stations, wherein at least one of the received transmissions includes an acknowledgement message. Then determining a rate control command included within transmissions of the base station that includes the acknowledgement message and using the command to control the data rate. Controlling the data rate also includes receiving transmissions from a plurality of base stations. Then determining a plurality of rate control commands included within the received transmissions from the plurality of base stations. The rate control commands are then combined and used to control the data rate.

A method of facilitating a silence period in a directional communication network is provided. The method may comprise initiating, by a first apparatus, a listening period mode, wherein the listening period mode comprises ceasing at least a portion of current communication and configuring the first apparatus to receive a request to initiate a new communication, determining whether a request is received during a time period in the listening period mode, and transmitting a response if the request to initiate the new communication is received during the time period in the listening period mode.

Techniques for performing duplicate detection and re-ordering for a HARQ transmission are described. For duplicate detection, a receiver determines whether a decoded packet x for an ARQ channel y is a duplicate packet based on packet x and a prior decoded packet for ARQ channel y. For re-ordering, the receiver determines whether an earlier packet is still pending on any other ARQ channel based on prior decoded packets for the ARQ channels and forwards packet x only if there are no pending earlier packets. There are no pending earlier packets on another ARQ channel z if (1) a decoded packet was received on ARQ channel z at a designated time or later or (2) a decoded packet was not received on ARQ channel z within a time window from current time.
