Abstract

A two-way audiovisual communication device with multiple audio and video subsystems. In one embodiment, the device includes a wheeled cart that supports a dock for a tablet computing device that includes a tablet camera, a tablet display, and a tablet microphone. The device also includes a cart camera, a cart speaker, and a cart microphone. The device may be coupled to a network and accessible to other devices on the network to allow a two-way audiovisual session to take place between remote parties. The device may operate in two modes: In a first mode, the tablet is mated with the dock and the remote device receives video from the pan-tilt-zoom camera and audio from the cart microphone. In a second mode, the tablet is removed from the dock and the remote device receives video from the tablet camera and audio from the tablet microphone. In both modes, the tablet monitor displays video from the remote device.

First claim

What is claimed is:

1. A telemedicine system comprising:
a cart that supports a cart camera and a dock that is electrically coupled to the cart camera and adapted to receive a tablet device that includes a tablet camera; and
a remote device communicatively coupled to the tablet via a network, the remote device including a display device that displays video received from the tablet device during a communication session, wherein the video received from the tablet device is automatically switched, without interrupting the communication session, between video from the cart camera and video from the tablet camera depending on whether the tablet is coupled to the dock such that the display device displays video captured by the cart camera when the tablet is coupled to the dock and the display device displays video captured by the tablet camera when the tablet device is decoupled from the dock and the cart camera.

2. The system of claim 1 , wherein the dock includes a plurality of electrical contacts that mate with the tablet when the tablet device is coupled to the dock.

3. The system of claim 2 , wherein the cart further includes a power system that is coupled to tablet via one or more of the plurality of electrical contacts when the tablet is coupled to the dock.

4. The system of claim 3 , wherein the power system includes a battery.

5. The system of claim 3 , wherein the power system includes a battery charger.

6. The system of claim 3 , wherein the power system includes an AC power plug attached to the cart via a power cord.

7. The system of claim 2 , wherein the cart camera is coupled to the tablet via one or more of the plurality of electrical contacts when the tablet is coupled to the dock.

8. The system of claim 2 , wherein the cart supports a cart speaker and a cart microphone, the cart speaker reproduces audio captured by a microphone of the remote device and the remote device includes a speaker that reproduces audio captured by the cart microphone.

9. The system of claim 8 , wherein the cart speaker and the cart microphone are coupled to the tablet via one or more of the plurality of electrical contacts when the tablet is coupled to the dock.

10. The system of claim 8 , wherein the tablet includes a tablet speaker and a tablet microphone, wherein, when the tablet is decoupled from the dock, the tablet speaker reproduces audio captured by a microphone of the remote device and the remote device includes a speaker that reproduces audio captured by the tablet microphone.

11. The system of claim 1 , wherein the tablet device includes a display device, the remote device includes a camera, and the tablet display device displays video captured by the remote device camera.

12. The system of claim 11 , wherein the tablet display device is a touchscreen.

13. The system of claim 12 , wherein the tablet display device displays one or more physiological values received via a medical peripheral coupled to the tablet.

14. The system of claim 1 , wherein the cart camera is a pan-tilt-zoom camera and can be controlled by a user input via the remote device.

15. The system of claim 1 , wherein the dock includes a latching mechanism for securing the tablet when coupled to the dock.

16. The system of claim 15 , wherein the latch includes a lock.

17. The system of claim 1 , wherein the cart supports a work surface.

18. The system of claim 1 , wherein the cart supports a drawer.

19. The system of claim 1 , wherein the height of at least one of the dock and the cart camera is adjustable.

20. The system of claim 1 , wherein the cart includes a peripheral communication port that can be coupled to peripheral device and the tablet via a communication bus.
