Abstract: Systems and methods for presence-based account data association with devices are disclosed. For example, a presence event may be detected and details of the presence event may be utilized to determine whether and how to initiate, maintain, or end an account-association session associated with a secondary device. A current session status and a determination as to whether a primary device is associated with a previously-utilized primary account identifier for the secondary device may be used to determine whether connection notifications should be sent and/or whether the secondary device should be within a threshold distance from a primary device to establish the account-association session.

Abstract: The present disclosure provides a heparin neutralizing peptide, a heparin neutralizer, and use thereof, and belongs to the technical field of biomedicine. The heparin neutralizing peptide includes tandem repeating units. The repeating units each have an amino acid sequence shown in SEQ ID NO: 1, specifically VPGKG, where lysine (K) has a positive charge, the repeating units each have a positive charge, and the heparin neutralizing peptide has a plurality of positive charges. The heparin neutralizing peptide with positive charges can bind to a heparin with negative charges through electrostatic interaction to form macromolecular substances, and the macromolecular substances are eliminated from the body by liver metabolism, so that the anticoagulation of the heparin is shielded. Furthermore, the heparin neutralizing peptide provided in the present disclosure can significantly reduce toxic and side effects of neutralizing heparin and reduce hemolysis compared with protamine sulfate in the prior art.

Abstract: A complex surface three-coordinate measuring device includes a three-degree-of-freedom motion platform and a force control probe, the force control probe is fixedly mounted on the Z-axis sliding block, which is in the same direction as the X-axis direction and used to contact with the workpiece surface with constant force. A six-axis force sensor is used to collect the contact force between the stylus and the workpiece surface. In this method, the force control is realized in the measurement to make the stylus in constant force contact with the workpiece surface. The error compensation direction is determined according to the direction of the contact force, and then the effective radius of the stylus spherical head is compensated in this direction, thus the actual contact point of stylus and workpiece can be obtained.
