Abstract: Systems and methods related to “on/off” determinations regarding the performance of physical downlink control channel (PDCCH) monitoring during connected mode discontinuous reception (CDRX) on duration windows are disclosed herein. In some cases, a radio access network (RAN) predicts whether a downlink (DL) packet for a UE will arrive at a buffer of the RAN prior to an end of a CDRX on duration window of the UE, and sends a downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a power-saving radio network temporary identifier (PS-RNTI) (DCP) for the CDRX on duration window indicating whether or not the UE should perform PDCCH monitoring during the CDRX on duration window based on the prediction. In some cases, a UE determines a current state of DL traffic and adaptively uses DCP monitoring based on the current state of the traffic. Aggregation level adaptation by the RAN is also discussed.

Abstract: An identity authentication method is disclosed in embodiments of the present application. When a requester and an authentication access controller perform identity authentication using an authentication mechanism of a pre-shared key, the identity information of entities is transmitted in the form of ciphertext, thereby preventing the identity information of the entities from being exposed during the transmission, so that attackers cannot obtain private or sensitive information. The mutual or unilateral identity authentication between the authentication access controller and the requester is achieved while ensuring the confidentiality of the entity identity and related information, thereby laying a foundation for ensuring that the user accessing the network is legitimate and/or the network accessed by the user is legitimate.

Compared with the object data obtain in a conventional way, the real object data obtained by the method for improving object detection accuracy is more accurate, and this is especially true when the object velocity is excessive high.

Abstract: A two-degree-of-freedom decoupled transmission apparatus for a spatial adhesion pawl mainly includes a tangential loading transmission mechanism and a normal de-adhesion transmission mechanism. The tangential loading transmission mechanism adopts a bevel gear pair, such that the tangential loading transmission mechanism is arranged in a bending manner, and a tangential loading motor of the tangential loading transmission mechanism is collected inside the apparatus. The tangential loading motor is connected to a cam pull plate through the bevel gear pair, a worm gear reducer and a key, and drive the cam pull plate to rotate around a central shaft of an adhesion apparatus. Six transmission bolts on six adhesion units are respectively driven through six cam grooves on the cam pull plate to simultaneously perform centripetal driving on the adhesion units with a further increased force, so as to realize tangential and centripetal loading of the adhesion units.

Abstract: Various embodiments of the present technology generally relate to power topology discovery in industrial environments. More specifically, some embodiments relate to automatic power topology discovery for factories based on device data that is already recorded for other purposes. Systems and methods described herein may be used to generate an accurate electrical network topology by collecting power data from power devices that may provide real-time or recorded measurements, detecting power change events, and matching power change signatures over power events for the devices in order to calculate the likelihoods of possible topology assumptions. Power change event data is used to recursively update topology probabilities using the Bayesian formula until a system topology can be produced with satisfactory confidence.
