Appl. No.:

11/968864

Inventors:

Kentaro Oguchi - Ichinomiya, JP
David Weir - San Jose CA, US

International Classification:

G08G 1/16
G06F 17/10

US Classification:

701301

Abstract:

A system and method for predicting driver behavior and generating control and/or warning signals comprises: one or more sensors; a database; a driver predictor for generating warning and control signals; a notification unit; and a vehicle control unit. More specifically, the driver predictor includes a transfer module, a hierarchical temporal memory and a prediction retrieval module. The transfer module is used to receive data and translate it into a form so that it can be stored in the hierarchical temporal memory. The hierarchical temporal memory receives data input and stores it such that data items are translated into short-term memory items which are in turn translated into intermediate-term data which in turn are finally translated into long-term data. The translation of data from one level of the memory to another is performed according to the present invention such that the data at each level of memory is reflective of and predictive of a particular driver behavior. Once the data is stored in the memory, the prediction retrieval module accesses the hierarchical temporal memory to generate warning signals to alert the driver of potentially dangerous conditions and/or control systems of the vehicle to prevent or avoid collisions. The present invention also includes a variety of method including a method for storing driving data in a hierarchical temporal memory, and a method for using a hierarchical temporal memory to generate collision avoidance signals.

International Classification:

A61B 17/068
A61B 19/00

US Classification:

227 2, 2271751

Abstract:

Systems and methods are provided for detecting failure in clamping of a material and/or firing of a staple into a clamped material and indicating such failure to a user on a user interface. The system and methods are particularly suited for use with end effectors having closing and/or firing mechanisms coupled to an actuator. By monitoring a driving parameter of an actuator that effects the clamping and/or firing, the systems and methods provide an indication of failure in response to the monitored drive parameter. In some embodiments, an indication of failure is output when the monitored drive parameter is outside an acceptable range of desired driving parameters during clamping and/or firing. The disclosed systems and methods are particularly beneficial when used for minimally invasive surgery.

US Classification:

606205

Abstract:

End effectors with closing mechanisms, and related tools and methods are disclosed. The disclosed end effectors may be particularly beneficial when used for minimally invasive surgery. An example surgical tool comprises a first and second jaw movable between a closed grasped or clamped configuration and an open configuration. The tool further comprises a soft grip mode for grasping the tissue at a first force during which a separation parameter between the jaws is measured, and a therapeutic clamping mode in which the jaws clamp on the body tissue at a force greater than the grasping force. The methods comprise grasping the body tissue between jaw members, measuring the separation parameter between jaws, indicating on a user interface the separation parameter for comparison to a desired separation parameter, and then releasing the body tissue for repositioning or therapeutically clamping the body tissue in response to the separation parameter indication.

David W. Weir - Emerald Hills CA, US

Assignee:

INTUITIVE SURGICAL OPERATIONS, INC. - Sunnyvale CA

International Classification:

A61B 17/068

US Classification:

227 2

Abstract:

Systems and methods are provided for detecting misfire of a surgical staple cartridge and for indicating such misfire to a user on a user interface. An actuation force applied to a staple cartridge is measured and compared to a threshold actuation force. In response to the comparison, a controller determines if there has been a misfire of the surgical staple cartridge. A determination that misfire has occurred is made when the measured actuation force is greater than a maximum threshold force or less than a minimum threshold force, and under such circumstances, the controller terminates the staple firing sequence.

International Classification:

US Classification:

606130, 403326

Abstract:

A latch mechanism selectively retains a first assembly to a second assembly. The first and second assemblies are configured for sliding engagement along an engagement axis. The latch mechanism includes a latch shaft mounted to the first assembly to rotate about a latch shaft axis, a torsion spring to bias the latch shaft relative to the first assembly, and a transverse latch member coupled with the second assembly. The latch mechanism is configured to automatically latch in response to the first assembly being pushed toward the second assembly. The transverse latch member interacts with the latch shaft to rotate the latch shaft in a first direction in response to movement of the first assembly toward the second assembly. Further motion of the first assembly toward the second assembly results in rotation of the latch shaft opposite to the first direction into a retention configuration that retains the transverse latch member.
