A method for assisting the navigation of a fleet of vehicles including main vehicle and a secondary vehicle movable relative to the main vehicle includes receiving data acquired by one or more sensors, the received data including relative kinematic data between the main vehicle and the secondary vehicle, and estimating a navigation state of the fleet of vehicles by an invariant Kalman filter using the received data as observations. The navigation state includes first variables representative of a first rigid transformation linking a frame attached to the main vehicle to a reference frame, and second variables representative of a second rigid transformation linking the frame attached to the main vehicle to a frame attached to the secondary vehicle. The invariant Kalman filter uses as binary operation an operation including a term-by-term composition of the first rigid transformation and of the second rigid transformation.

The disclosure is directed to a system, device and method for data storage on implantable magnetizable fabric. The system includes implantable magnetizable fabric coupled to a graft segment of a prosthesis for being delivered into a body of a subject. The system includes information written on the implantable magnetizable fabric. The system further includes a magnetic detection device capable of, after the prosthesis is delivered into the body of the subject, detecting the implantable magnetizable fabric and accessing at least a portion of the information.

Methods of calculating a square of an input number in hardware logic are described. An m-bit number is received and Booth encoding is performed on different groups of three consecutive bits selected from the input to generate an encoded value for each of the groups. For each group, the method comprises forming a truncated string from the input number, generating an updated version of the truncated number and selecting a bit string based on the encoded value, the selected bit string comprising zeros or a left-shifted version of the updated version of the truncated number sign extended to a bit-width of 2m bits. The method further comprises combining the selected bit strings and square and sign bits for each group into an addition array; and summing the bits in the addition array.
