Abstract: An exemplary method of imaging tissue of a subject using a rolling shutter imager to provide a video stream comprises: sequentially resetting a plurality of rows of pixels of the rolling shutter imager from a first row to a last row; transitioning a liquid crystal shutter from a closed state to an open state; after the liquid crystal shutter is transitioned into the open state and after resetting the last row, illuminating the tissue of the subject with an illumination light for an illumination period to accumulate charge at the plurality of rows of pixels, and after the illumination period ends, sequentially reading the accumulated charge at the rows of pixels from the first row to the last row; generating an image frame from the sequentially read accumulated charge at the plurality of rows of pixels; and adding the image frame to the video stream.

Abstract: A surgical camera system comprising: a camera head including a housing; an image sensor within the housing; and the housing including a liquid lens therein for focusing an image received in the housing prior to transmission of the image to the image sensor, and a fixed solid lens adjacent the liquid lens.

Abstract: A cable for connecting a medical imaging device to a medical imaging controller includes a first connector located at a distal end of the cable for connecting to the imaging device, a second connector located at a proximal end for connecting to the medical imaging controller, a circuit board comprising at least one memory that stores at least authentication information associated with the cable. The circuit board is communicatively connected via a communication bus on the circuit board to the second connector for enabling access to the authentication information by the medical imaging controller. One or more imaging communication lines extend between the first connector and the second connector for communicating imaging data from the medical imaging device to the medical imaging controller. The one or more imaging communication lines bypass the communication bus on the circuit board.

Abstract: A patient support apparatus system includes sensors adapted to sense a gesture of a person, or forces exerted by the person on the patient support apparatus, and to control the movement of a component of the patient support apparatus based on the gesture or forces. The movement of the patient support apparatus matches the direction of the person's gesture or applied forces. The speed of the gesture and magnitude of the applied force also influence the movement of the patient support apparatus component. The controlled movement may be the upward and downward motion of a patient support deck on the patient support apparatus, or it may be the pivoting of a section of the patient support deck, or it may be other movement. Control of the patient support apparatus is carried out based on the intent of the user, as evidenced by the user's gesture or applied forces.
