Patent number: 9616576Abstract: A remote controlled robot system that includes a robot and a remote control station. The robot includes a binaural microphone system that is coupled to a speaker system of the remote control station. The binaural microphone system may include a pair of microphones located at opposite sides of a robot head. the location of the microphones roughly coincides with the location of ears on a human body. Such microphone location creates a mobile robot that more effectively simulates the tele-presence of an operator of the system. The robot may include two different microphone systems and the ability to switch between systems. For example, the robot may also include a zoom camera system and a directional microphone. The directional microphone may be utilized to capture sound from a direction that corresponds to an object zoomed upon by the camera system.Type: GrantFiled: September 10, 2014Date of Patent: April 11, 2017Assignee: INTOUCH TECHNOLOGIES, INC.Inventors: David Bjorn Roe, Daniel Steven Sanchez, Marco Pinter, Derek Walters, Charles S.

Patent number: 9600631Abstract: A tele-presence system that includes a cart. The cart includes a robot face that has a robot monitor, a robot camera, a robot speaker, a robot microphone, and an overhead camera. The system also includes a remote station that is coupled to the robot face and the overhead camera. The remote station includes a station monitor, a station camera, a station speaker and a station microphone. The remote station can display video images captured by the robot camera and/or overhead camera. By way of example, the cart can be used in an operating room, wherein the overhead camera can be placed in a sterile field and the robot face can be used in a non-sterile field. The user at the remote station can conduct a teleconference through the robot face and also obtain a view of a medical procedure through the overhead camera.Type: GrantFiled: June 18, 2015Date of Patent: March 21, 2017Assignee: INTOUCH TECHNOLOGIES, INC.Inventors: David Stuart, Daniel Steven Sanchez, Fuji Lai, Kevin Hanrahan, Charles S.
