Title: Noise cancellation in railway cab signal
Inventor: CAPAN RONALD R
IPC: B61L3/24
Filed: 1995-05-19
Granted: 2001-01-09
Abstract: A cab signaling apparatus for use on board a railway vehicle which is propelled on rail tracks by an electric drive motor.  The invention utilizes a cab signal transmitted to the vehicle through a track circuit in the rails.  On board receiving of the cab signal is done by a receiving coil, which may be mounted in front of the lead axle, as a current transformer around the lead axle, or at another location where the cab signal current is relatively strong.  The cab signal that is sensed has a cab signal component and an interference component.  On board the vehicle a sampled signal is taken which has the characteristic of the electromagnetic interference subjected to the cab signal receiver coil.          The sampled signal is then subtracted from the sensed cab signal such that the sampled interference signal cancels the interference component of the cab signal.          Embodiments include placing the sampling means as an inductive coil behind the lead axle and in other embodiments in front of the lead axle above the cab signal sensing coil.  In some embodiments the noise sampling coil is at 90 degrees to the cab signal receiving coil.  A series arrangement with selective polarity on the coils permits a vital arrangement.  In some embodiments the sampling to achieve a sampled signal characteristic of electromagnetic interference is done by using a current transformer coil on the electric drive motor cable.

Abstract: A system for recording and displaying ultrasound images is disclosed. The system includes a database server, an ultrasound image capture station and an ultrasound image review station. The ultrasound images are captured from an analog video signal stream output by an ultrasound machine and converted into compressed digital data preferably in MPEG format. The compressed digital data is archived to a compact disc recordable medium for permanent storage. The ultrasound images may be annotated by a sonographer as they are captured. The sonographer selects an annotation icon from a predefined list of icons to highlight points of interest in an ultrasound scan. The system also includes a demographic data module for trackingcaptured ultrasound scans, and a clinical data module for reporting ultrasound findings and diagnoses. The advantages include reduced storage requirements because of the elimination of video tape; more accurate tracking of ultrasound scans; easier review due to perfect still frames, random access, annotated highlights and zoom capability; faster more accurate reporting of findings and diagnosis; and, the ability to share ultrasound images over local and wide area networks.
