Abstract: A system and method of training how to use a medical device using an instrument such as a mock ultrasound probe or syringe to be tracked in 3D space with six degrees of freedom using an internal optical camera, a light source (e.g. infrared LEDs), and a display of markers arranged on a surface. By extracting corner information for each marker, a 3D transformation can be established, allowing the system to know the instrument's position and orientation in 3D space relative to that marker. Each marker also encodes a numerical value corresponding to its predetermined position and orientation on the surface, allowing the instrument to determine its own position and orientation relative to the surface. Thus, as long as the instrument is able to see at least one marker on an optical surface, the system will know its full 3D position and orientation relative to the whole optical surface.

Abstract: A training system to teach use of an ultrasound probe, the training system having a chamber defining an orifice, a shaft insertable into the orifice of the chamber, a marker positioned on the shaft at a distal end, a camera positioned to view the marker when inserted inside the chamber, and a processor operatively connected to the camera for processing a position and an orientation of the shaft based on the marker. The system provides a method for visualizing movement of the shaft from inside the chamber.

Abstract: The Tuohy needle of the present invention includes a hub design that allows for the needle to be extended mid-procedure from 3.5? to 5?. The extendable needle of the present invention allows practitioners to better accommodate overweight and obese patients and introduce a simpler procedure workflow.

Abstract: A combination of components in a capillary flow channel use capillary forces to passively control the movement of liquid samples within a microfluidic device. To detect a target, a liquid sample introduced to a proximal portion of capillary channel of a microfluidic device moves by capillary action along the specific components of capillary channel.

Abstract: A method for processing services can include receiving a request for a service; sending the result of the service in which at least one data item is tagged; in response to a selection of the tagged data item, determining other services associated with the service based on a service template of the service; and providing the other services associated with the service as options, wherein the other services take the at least one data item as inputs to provide outputs thereof.

Abstract: Methods and systems for detection of a construction zone sign are described. A computing device, configured to control the vehicle, may be configured to receive, from an image-capture device coupled to the computing device, images of a vicinity of the road on which the vehicle is travelling. Also, the computing device may be configured to determine image portions in the images that may depict sides of the road at a predetermined height range. Further, the computing device may be configured to detect a construction zone sign in the image portions, and determine a type of the construction zone sign. Accordingly, the computing device may be configured to modify a control strategy associated with a driving behavior of the vehicle; and control the vehicle based on the modified control strategy.
