Abstract: An acoustic signal cancellation system is configured to perform: (a) provide a user device, associated with the system, and an audio capture device. (b) receive at system a captured signal indicative of a captured acoustic signal. It's received at capture device, and comprises a second acoustic signal generated by a second device, external to user device. (c) receive, from external source, a reference signal, indicative of a content included in the second signal. (d) in a case that a content of reference signal and the content in second signal are not time-synchronized, generate a synchronized reference signal, based on reference signal. Content of synchronized reference signal and second signal content are time-synchronized. (e) perform acoustic signal cancelling of that portion of captured signal which corresponds to second signal, based on reference signal. Generate reduced signal. This facilitates output of reduced signal to third device.

Abstract: An exemplary system may allow concurrent access to a device by different virtual machines. In one embodiment, the system receives a request to add a virtual machine (VM) of a plurality of virtual machines to a host, the request identifying a device that is shared by the plurality of virtual machines. The system creates a VM-specific rule for the device based on the VM. The system stores the VM-specific rule for the device in association with the VM.

Abstract: An exemplary system may allow new devices to be added. In one embodiment, upon receiving information associated with a device event, the system generates a first rule for a device based on the information and a system state. The system determines determine an updated system state based on the first rule. The system determines whether a second rule is required for the updated system state. Upon determining that the second rule is required for the updated system state, the system generates the second rule.

Abstract: An exemplary system may automatically discovery externally added devices. In one embodiment, the system obtains initial device information for a virtual machine running on a host computing system. The system determines whether an external event occurred on the host computing system. A management computing system associated with the host computing system does not receive notification of the external event. Upon determining that the external event occurred on the host computing system, the system obtains updated device information for the virtual machine running on the host computing system.
