Abstract: A network exposure node receives a reference identity for the network exposure node in a first monitoring message from a first network node. The network exposure node further retrieves, based on the reference identity for the network exposure node, an identity list of one or more subscriber UEs, which subscribed to monitoring of an event, and configuration information for the one or more subscriber UEs, which are stored in the network exposure node. The network exposure node then determines, based on the identity list and the configuration information, a second network node associated with a subscriber UE in the identity list. Next, the network exposure node transmits a report for the monitoring of the event in a second monitoring message to the determined second network node.

Abstract: A method (400) in an SCEF node for facilitating non-IP UE-to-UE communications is provided. The method (400) includes: receiving (420) from a first MME/SGSN associated with a source UE a Create SCEF Connection Request containing an identity of the source UE and an identity of a destination UE; receiving (430) from the first MME/SGSN an MO NIDD Submit Request containing the identity of the source UE and a non-IP data from the source UE; and transmitting (440) an MT NIDD Submit Request containing the non-IP data to a second MME/SGSN associated with the destination UE.

Abstract: A method for arranging sensors and a sensor arrangement structure, pair sensors by adding an additional sensor, and sets an operating mode between the sensors in an “OR” mode by a software. When one of the sensors become abnormal, an apparatus operates normally, which lowers a probability of crash of the apparatus, reduces loss of production capacity and raises production rate.

Abstract: A catalyst for catalytic oxidation treatment of organic wastewater, comprising aluminum oxide, and nickel, ferrum, manganese, and cerium supported on the aluminum oxide in oxide form. Based on the weight of aluminum oxide, the contents of the following components in the catalyst are: nickel: 5.0-20 wt %; ferrum: 0.5-5.5 wt %; manganese: 0.5-3.5 wt %; and cerium: 1.5-3.0 wt %. The present invention has a good effect in catalytic oxidation for degrading COD organic pollutants in wastewater and has high reactivity.

Abstract: A method for treating reverse osmosis concentrated water, comprises adding precipitant and oxidant to reverse osmosis concentrated water for treatment, filtering to obtain clear liquid, and adding catalyst for water treatment to clear liquid for catalytic oxidation to obtain a first-stage treated water. Optionally, the liquid may be subjected after catalytic oxidation to an adsorption treatment; performing reverse osmosis treatment on first-stage treated water to obtain second-stage reverse osmosis product water and second-stage reverse osmosis concentrated water; and adding oxidant to second-stage reverse osmosis concentrated water for oxidation treatment to obtain directly discharged effluent water. The obtaining of effluent water may further comprise subjecting liquid after oxidation treatment to adsorption treatment. The above method can recycle 75-85 wt % of water, and operates easily.

Abstract: A system for estimating range to an object comprising a system for estimating range to an object comprising a transmitter to transmit at least one UWB signal, a receiver to receive at least one UWB signal, a sampler to sample the received UWB signal depending on a plurality of clock and/or sample pulses having a first frequency, and a circuit and/or processor configured to generate a fractional signal having a second frequency that is lower that the first frequency and a phase that is dependant on the delay between when the UWB signal is actually received and when the received UWB signal is first sampled, and determine the range based on at least a first number of clock or sample pulses between transmitting and receiving the UWB signal and the phase of the fractional signal. Also a method of estimating range to an object.
