Systems, apparatuses, and methods for implementing a combo scheme for direct current (DC) level shifting of signals are disclosed. A receiver circuit receives an input signal on a first interface. The first interface is coupled to a resistor in parallel with a capacitor which passes the input signal to a second interface. Also, the first interface is coupled to a first pair of current sources between ground and a voltage source, and the second interface is coupled to a second pair of current sources between ground and the voltage source. An op-amp drives the current sources based on a difference between a sensed common mode voltage and a reference voltage. Based on this circuit configuration, the receiver circuit is able to prevent baseline wander, perform a DC level shift of the input signal, and achieve linear equalization of the input signal.

Methods and system perform tool tracking during minimally invasive robotic surgery. Tool states are determined using triangulation techniques or a Bayesian filter from either or both non-endoscopically derived and endoscopically derived tool state information, or from either or both non-visually derived and visually derived tool state information. The non-endoscopically derived tool state information is derived from sensor data provided either by sensors associated with a mechanism for manipulating the tool, or sensors capable of detecting identifiable signals emanating or reflecting from the tool and indicative of its position, or external cameras viewing an end of the tool extending out of the body. The endoscopically derived tool state information is derived from image data provided by an endoscope inserted in the body so as to view the tool.

Techniques described herein improve database security by reducing network attack surface area in conjunction with deep input validation. In an embodiment, a database session receives one or more network packets sent via a network, the database session including a database session state that specifies one or more database privileges. The database session reads said one or more network packets into one or more request-packet-buffers, wherein said one or more request-packet-buffers include an RPC op code for a database operation. Based on the one or more database privileges associated with the user associated with the database session, the database session determines whether the RPC op code may be executed. In response to determining that the RPC op code may be executed by said database session, the RPC op code is executed. In response to determining that the op code may not be executed by said database session, the execution of the RPC op code is prevented.

A medical system may comprise a stereo display and an input device. The medical system may also comprise a processor configured to generate a three-dimensional image of an anatomical object and cause the three-dimensional image of the anatomical object and a two-dimensional window to be displayed. The processor may also be configured to cause a position and an orientation of the two-dimensional window relative to the three-dimensional image of the anatomical object to be changed on the stereo display by manipulation of the input device. The processor may also be configured to define a cut-plane to indicate a two-dimensional slice of the three-dimensional image of the anatomical object. The processor may also be configured to cause the two-dimensional slice of the three-dimensional image of the anatomical object to be displayed. An orientation of the displayed two-dimensional slice may be different than an orientation of the cut-plane with the three-dimensional image.
