Methods and systems for controlling a surgical microscope. Moveable optics of the surgical microscope are controlled using two sets of control parameters, to reduce jitter and image instability. Shifts in the image due to changes in temperature or due to the use of optical filter can also be compensated. Misalignment between the mechanical axis and the optical axis of the surgical microscope can also be corrected.

Surgical optical zoom system

Surgial optical zoom system

A system for producing 3D video using first and second cameras on first and second axes. The second camera has a field of view (FOV) overlapping with the first camera's FOV. The second axis is at a convergence angle relative to the first axis. A control computer changes the inter-camera distance by effectively moving the second camera laterally, and changes convergence angle by effectively rotating the second camera. The control computer automatically calculates the inter-camera distance and convergence angle based on the distance of a user to the display screen, working distance of the cameras, zoom settings, and size of the screen, and effectively moves the second camera accordingly. A keystone correction is performed to account for the camera projections, the frames are rotationally aligned, and the corrected/aligned frames are combined to produce a 3D image frame that is displayed on a 3D display screen.

Systems and methods for providing a connection of a client to an unmanaged service in a client-server remote access system. An unmanaged service may register at a remote access server and open a communication connection there between remote access server may be configured for providing remote access to the unmanaged service by a client. The remote access server receives keep-alive messages from the unmanaged service over the communication connection, which may serve to indicate that the unmanaged service is operational. The remote access server may a request for a client connection to the unmanaged service, after which, a terminate keep-alive message is communicated to the unmanaged service to terminate the sending of keep-alive messages from the unmanaged service in response to the request for the client connection to the unmanaged service.

A surgical user interface system and methods, involving: an interface having at least one overlay element of: at least one menu bar, at least one tab, at least one sidebar, at least one window, at least one icon; at least one graphical control element, at least one haptic control element, and at least one voice control element, the interface configured to: communicate with at least one surgical system, the at least one surgical system having at least one of an imaging system, a guidance system, a control system, a tracking system, a navigation system, a drive system, and a voice recognition system; display information corresponding to at least one surgical parameter of the at least one surgical system; overlay a real-time streaming image from the imaging system; receive input by way of the at least one overlay element; transmit the input to the at least one surgical system; and update, in real-time, the at least one overlay element in response to a change in the at least one surgical parameter.

User interface system and methods for overlaying surgical video output

Systems and method for providing a collaborative conferencing capability to an application remotely-accessed by client computing devices. A client media sharing application is provided in a client tier, and the client media sharing application allows at least one of the client computing devices to share media with the client computing devices. A conferencing manager application that receives the shared media is provided to the server tier. The conferencing manager application makes the shared media available to the client computing devices.

A system and method for stabilizing video using a census kernel having test points. A subset form a connected circle centered on the kernel's center point. For each candidate pixel, a signature is calculated based on the relative brightness of the candidate pixel and of the pixels corresponding to test points when the kernel overlays the image with the center point over the candidate pixel. A candidate pixel is designated to be a corner pixel by processing the signature to determine that the candidate pixel is significantly brighter or darker than the test point pixels. For each corner pixel, a corresponding pixel in the previous frame is identified by comparing the signature of the corner pixel with signatures of pixels in the previous frame, and a corresponding motion vector is established. A motion model is calculated based on the motion vectors and applied to the digital frame.

Video stabilization system and method

A client-side flow control mechanism for controlling the flow of messages communicated from a service to a client in a remote access system. The service, which may be a managed or unmanaged service, may communicate messages to the client where the messages include a service sequence ID (SSI). As the client processes the messages from the service, the client responds with a client sequence ID (CSI). The SSI and CSI values determine the number of messages that are in transmission queues. The service compares a difference between the current SSI and CSI to a stop window value. If the difference is greater than the stop window value, transmission of messages from the service to the client is turned OFF. The client continues to send CSI acknowledgments as it processes messages. Once the difference falls below a start window value, the transmission of messages to the client is turned ON.

Methods and systems are provided herein for initiating real-time, peer-to-peer communication from a collaborative session. Real-time, peer-to-peer communication includes sharing content such as media content over a peer-to-peer connection such as peer-to-peer conferencing, for example. More particularly, from within the collaborative session where a plurality of clients collaboratively interact with a remotely-accessed application, for example, the systems and methods enable discovery of the clients actively participating in the collaborative session (e.g., peer nodes) and enable establishment of peer-to-peer connection(s) between pairs of the clients.

Methods and systems for peer-to-peer discovery and connection from a collaborative application session

A method and system for providing remote access to multi-channel audio by periodically polling channels of audio produced by, e.g., an application program by calling an Application Programming Interface (API). A method performs the polling to retrieve audio data from multiple channels and to mix the multiple channels into a mixed multichannel audio that is communicated to a remote computing device. The method transmits a sample minimum duration of audio data retrieved from all channels during at polling interval to provide low latency transmission of audio to remotely connected computing devices.
