Abstract: One embodiment is a baseline restoration (“BLR”) circuit for a photo-counting computed tomography (“PCCT”) signal chain, the BLR circuit comprising a comparator for comparing a shaper voltage output from a shaper component of the PCCT signal chain with a baseline voltage, the comparator outputting a single bit indicative of whether the shaper voltage is above or below the baseline voltage; a low pass filter connected to filter a voltage signal output from the comparator; and a transconductor connected to receive a filtered voltage signal output from the low pass filter, convert the filtered voltage signal to a current signal, and feed the current signal back to an input of the PCCT signal chain.

Abstract: There is disclosed herein examples of systems and methods for compressing a signal. Samples of the signal can be segmented and the samples within each of the segments can be averaged to produce a value that can represent the samples within the segment. The number of samples to average in each segment may be determined based on an error threshold, such that the number of samples being averaged can be maximized to produce less data to be transmitted while maintaining the representation of the samples within the error threshold. In some embodiments, a signal can be separated into a timing reference, a representative periodic function, and a highly compressible error signal. The error signal can be utilized for reproducing a representation of the signal.

Abstract: A contactless charging system for smart garments having coils whose centroids are not colinear. Folding a coil in half through its centroid will null out its inductance. A smart garment having 3 coils that have centroids that are not colinear is proposed. Accordingly, there is no single folding line that intersects all 3 centroids thereby nullifying inductance. Power can be combined with one or more rectifiers such that power is not cancelled. The present disclosure is suitable for any charging environment or apparatus, such as, drawer or hanger.

Abstract: Herein disclosed are approaches for protecting sensitive information within a fingerprint authentication system that can be snooped and utilized to access the device, secured information, or a secured application. The approaches can utilize encryption keys and hash functions that are unique to the device in which the fingerprint authentication is being performed to protect the sensitive information that can be snooped.

Abstract: A contactless charging drawer for smart garments using magnetic coupling links. A frame with a primary coil creates a magnetic field which couples with a secondary coil disposed a drawer. Smart garments, or any device, can then be safely charged in the drawer. The combination provides for a wireless power charging environment while adding an extra degree of freedom in impedance transformation without the need for electrical contacts to the drawer.
