Abstract: The invention relates to a quick calibration method for an inertial measurement unit (IMU). According to the method, a user holds and rotates the IMU to move in all directions without any external equipment, so that twelve error coefficients including gyro biases, gyro scale factors, accelerometer biases and accelerometer scale factors can be accurately calibrated in a short time. The quick calibration method for the IMU is characterized by being free of hardware cost, high in efficiency and simple and easy to implement, and can ensure certain calibration precision. Thus, the quick calibration method is especially suitable for in-situ quick calibration for the medium- and low-grade IMUs, thereby effectively solving the problem of environmental sensitivity of the error coefficients of the mechanical IMU, and promoting popularization and application of MEMS (micro-electro mechanical systems) inertial devices.

Abstract: The present invention is based, at least in part, on the discovery that strategic modifications of non-human donor antibody CDR residue(s) can be used to humanize antibodies. Such modifications modulate the 3D structural fit between donor antibody CDRs and human acceptor antibody framework regions that comprise the variable domains of a CDR-grafted antibody. Whereas prior art methods of humanization have relied on making framework substitutions (in which selected human framework residues are backmutated to the corresponding amino acid residue present in the non-human donor antibody), the instant invention is based, at least in part, on a method of humanizing antibodies in which selected CDR residues, and optionally adjacent FR residues, are changed in order to accommodate differences in FR amino acid sequences between donor and acceptor antibodies.
