Abstract: The invention relates to edible films, and more particularly to a method for preparing a food packaging film with antibacterial activity. By adding konjac glucomannan and glycerin in starch to obtain a composite film, the aggregation and rearrangement effect among molecules of amylose starch can be weakened, the defects such as high brittleness and low ductility of high-amylose corn starch can be improved, and, since the konjac glucomannan is rich in dietary fiber that is slowly digestible, a low-calorie edible packaging film can be produced by compounding. By adding the embedded product of perilla oil and cyclodextrin in the mixed dispersion of high-amylose corn starch and konjac glucomannan to prepare an active film, the film can have a smoother surface and more perfect and uniform structure, and also, the composite film can have a function of bacteria inhibition.

Abstract: System and method for testing transmission and reception performance of a data packet signal transceiver device under test (DUT). Data packet signals transmitted by a tester with a tester transmit output power (TTOP) contain trigger frames that include data corresponding to a reported tester transmit power (RTTP) of the data packet signals, and a desired received signal strength (TRSS) of DUT data packet signals to be received by the tester. Based on received signal strength of the tester data packet signals reported by the DUT (DRSS), responsive DUT data packet signals having a DUT transmit output power of RTTP?DRSS+TRSS. Successive repetitions of such tester and DUT data packet signals for multiple combinations of values of the TTOP, RTTP and DRSS enable testing transmission and reception performance of the DUT, including determining minimum and maximum DUT transmission power levels, with minimal signal interactions between tester and DUT.

Abstract: The present disclosure selects third party content based on feedback. A selector identifies several content items including first and second content items (or more) responsive to a request. A machine learning engine determines a first feature of the first content item, a second feature of the second content item, and a third feature of the web page or a device associated with the request. The machine learning engine determines, responsive to the first feature and the third feature, a first score for the first content item based on a machine learning model generated using historical signals received from devices via a metadata channel formed from an electronic feedback interface. The machine learning engine determines a second score for the second content item responsive to the second feature and the third feature. A bidding module determines a price for the first content item based on the first and second scores.

Abstract: Traffic associated with user equipment that are coupled to a first radio access network is steered to a second radio access network based on an adaptable signal strength criterion. The signal strength criterion is related to real-time network load conditions of the first radio access network and can be broadcasted from a serving access point to the user equipment. Moreover, the signal strength criterion facilitates steering, to the second radio network, traffic associated with user equipment that are located closer to a cell edge of the first radio access network before steering traffic associated with user equipment are located further away from the cell edge. In addition, based on the network congestion within the first radio access network, the signal strength criterion is modified to adjust the number of user equipment that are steered to the second radio network.
