Methods and systems for a data marketplace in a conveyor environment
Methods and systems for a data marketplace in a conveyor environment includes a self-organizing data marketplace. The self-organizing data marketplace includes at least one data collector and at least one corresponding conveyor in an industrial environment, wherein the at least one data collector is structured to collect detection values from at least one sensor of a power roller of the at least one corresponding conveyor; a data storage structured to store a data pool comprising at least a portion of the detection values; a data marketplace structured to self-organize the data pool; and a transaction system structured to interpret a user data request, and to selectively provide a portion of the self-organized data pool to a user in response to the user data request.
Method and device for group delay variation compensation
A method for compensating group delay variations in a CDMA spread spectrum receiver, comprising: receiving an RF signal; generating an ideal replica signal; filtering the RF signal by one or more filters; obtaining an ideal auto-correlation function (ACF) of the ideal replica signal; distorting the ideal ACF to generate a distorted ACF by a filtering model of the one or more filters; aligning the ideal ACF and the distorted ACF; calculating a set of correction factors based on a ratio of the ideal ACF and the distorted ACF; calculating a cross-correlation signal based on the filtered RF signal and the ideal replica signal; and obtaining a compensated correlation signal by applying the set of correction factors to the cross-correlation signal.

Method and apparatus of link adaptation in wireless local area network
A method of link adaptation performed by an access point supporting multi user (MU) multiple input multiple output (MIMO) in wireless local area network system is provided. The method includes transmitting, to a first station, a physical layer convergence procedure (PLCP) protocol data unit (PPDU) containing a modulation and coding scheme (MCS) request (MRQ) and receiving, from the first station, a MCS feedback (MFB) in response to the MRQ, wherein the first station is one of destination stations of MU-MIMO transmission performed by the access point, and the MFB includes a recommended MCS value computed, by the first station, on the assumption that the first station, as a member of the destination stations, receives data transmitted over at least one spatial stream allocated to the first station in MU-MIMO transmission.
Determining propagation delay of communications in distributed antenna systems, and related components, systems, and methods
Components, systems, and methods for determining propagation delay of communications in distributed antenna systems are disclosed. The propagation delay of communications signals distributed in the distributed antenna systems is determined. If desired, the propagation delay(s) can be determined on a per remote antenna unit basis for the distributed antenna systems. The propagation delay(s) can provided by the distributed antenna systems to a network or other system to be taken into consideration for communications services or operations that are based on communications signal delay. As another non-limiting example, propagation delay can be determined and controlled for each remote antenna unit to uniquely distinguish the remote antenna units. In this manner, the location of a client device communicating with a remote antenna unit can be determined within the communication range of the remote antenna unit.

Dynamic load balancing of satellite beams
A dynamic satellite load balancing system measures geographic position and travel information of in-flight aircraft in a fleet of aircraft equipped to establish in-flight connectivity services from a plurality of satellite beams. The in-flight aircraft include an on-board satellite map program with satellite map parameters to indicate which satellite beam of a group of available satellite beams is the most desirable based on the in-flight aircraft's geographic location. The system selects in-flight aircraft, determines load balanced satellite map parameters for the selected aircraft, and transmits the load balanced satellite map parameters to the aircraft to assemble load balanced satellite map programs to relieve wireless data communication saturation conditions on one or more of the satellite beams. The dynamic satellite load balancing system may transmit the load balanced satellite map parameters over an existing satellite data connection to make up-to-date adjustments to the communications load among the group of available satellite beams.
