Abstract: A lid controller hub (LCH) comprising processing components located in the lid of a mobile computing device, such as a laptop, processes sensor data generated by input sensors (microphones, cameras, touchscreen) and provides for improved and enhanced experiences over existing devices. For example, the LCH provides hardened privacy and the synchronization of touch display activities with the display refresh rate, the latter providing for a smoother and more responsive touch experience over existing designs. The LCH enables continuous gestures comprising touch gesture and in-air gesture portions as well as multi-plane gestures in which an initial touch gesture places the device into a mode or context in which it recognizes and acts upon subsequent in-air gestures. Touch operations of a mobile computing device can be based on user presence, user engagement, and a level of user interaction with the device.

Abstract: The present invention provides a method for managing requests for service over a communications network. The method of the invention comprises the steps of: receiving a request for service from a customer terminal at a queue server via the communications network; allocating a queue identifier to the request for service; sending the queue identifier to the customer terminal; receiving the queue identifier from the customer terminal at the queue server as part of a subsequent request for service; performing a comparison between the queue identifier and queue status information; and forwarding the request for service to the service host in accordance with the result of the comparison. Preferably, if sufficient resources are available, the request for service is forwarded directly to the service host without entering a queue. If there are insufficient resources, the request for service is held in an automatically managed queue and the risk of catastrophic failure is eliminated.
