Abstract: Disclosed herein are surgical assemblies comprising clamps with a lever clamp and a retractor arm that utilizes a ball-locking mechanism for clamping medical retractors. The ball-locking mechanism allows the retractor to be rotatable relative to the rod of the retractor arm. These assemblies allow for streamlined, accurate, efficient, and quick adjustments to retractors prior to or during surgery. They also obviate the need for a medical professional to hold the retractor in place during surgery and could reduce risk of human error during surgeries.

Abstract: During a transaction, a user may wish to determine if there are benefits available to the user, which may be applicable to the transaction with a resource provider. An application on the user device receives and transmits a resource provider identifier of the resource provider to a server computer. The server computer may identify a remote processor associated with the resource provider, and communicate with the remote processor to identify one or more benefits applicable to the transaction. The server computer may send the applicable benefit(s) to the application on the user device. The user may select one or more of the applicable benefits, and transmit the selection to the server computer, which may initiate processing of the transaction in view of the selected benefits.

Abstract: An mechanism for range estimation mapping that includes creation of a world map on an azimuth/elevation (AZ/EL) grid, relation of the grid to an earth-fixed north, east, and down (NED) coordinate system through an address table, and association of each pixel in each frame, by a programmable device, with an entry from the address table in order to determine a range is discussed. The associations may be repeated for each frame while an updated world map and address table are generated. When an updated address table is complete, the process may begin anew using the updated data.
