Abstract: Piezoelectric osteotomy devices and corresponding systems and methods for removing an acetabular cup or shell from a patient's acetabulum are disclosed. In one embodiment, the piezoelectric osteotomy device includes a piezoelectric element to actuate a cutting tip on an armature. In some such embodiments, the cutting tip may be extended and/or retracted to facilitate cutting of bone around an acetabular cup. The armature may include a fluid output port located proximate the cutting tip to mitigate heat generated by the cutting tip. In one embodiment, the piezoelectric osteotomy device is arranged and configured to provide constant current adjustment.

Abstract: A multi-user system to simultaneously perform operations such as communication, RADAR, Light Detection and Ranging (LIDAR) and Relative Navigation (RELNAV). The techniques according to an embodiment includes generating a Fourier based orthogonal chirp sequence of length P, a prime number greater than the number of users targeted for communication. The orthogonal chirp sequence is based on an identifier, in the range of one to P?1, associated with one of the targeted users. The method further includes using the orthogonal chirp sequence to generate a spread user signal based on a message directed to the one targeted users. The method further includes generating a sequence of training pulses for insertion into the spread user signal to facilitate reception of the signal. The method further includes transmitting and receiving a reflection of the spread user signal from one of the targeted users, the reflection used to detect and range the user.
