Methods, systems, and devices for facilitating joint submissions. In an example embodiment, a system may facilitate a joint submission from multiple devices. For example, a primary device may receive data for a joint submission with a peripheral device, and the data may be segmented into sensitive and non-sensitive data.

A semiconductor device capable of communicating with a host apparatus includes a symbol generation unit, a coding unit, and a transmission unit. The symbol generation unit includes a random number generation circuit and generates a symbol according to a random number generated by the random number generation circuit. The coding unit performs 8b/10b coding for the symbol. The transmission unit transmits the symbol coded by the 8b/10b coding unit to the host apparatus.

Apparatus and methods for a USB hub connected to USB host and one or more USB devices to support the USB host and the USB devices to dynamically switch roles such that a product which initially operates as a USB device operates a USB host while a USB host supports additional operation as a USB device. Products such as smartphones, initially operating as USB devices, may dynamically switch roles to become USB hosts. Similarly USB hosts, such as PCs and in-vehicle infotainment systems, initially operating as USB hosts may dynamically support additional operation as USB devices. The USB hub includes an upstream port connected to the USB host and one or more downstream ports connected to the products operating as USB devices and supports reconfiguring the downstream ports to upstream ports to enable the role switching the USB devices to become USB hosts while the USB hub maintains the upstream port connection to the USB host to operate as USB device.

Various embodiments comprise apparatuses and methods including a method of reconfiguring partitions in a memory device as directed by a host. The method includes managing commands through a first interface controller to mapped portions of a first memory not having an attribute enhanced set, and mapping portions of a second memory having the attribute enhanced set through a second interface controller. Additional apparatuses and methods are described.

An electrical power and/or electronic data unit with voice communications capability includes a housing, a voice communications module, and an electrical power outlet coupled to the housing. The voice communications module is coupled to the housing and includes an audio speaker, a microphone, an audio signal receiver/processor, and an audio signal generator. The audio signal receiver/processor is configured to receive and process vocalized speech from a user. The voice communications module is configured to generate an audible response via the audio signal generator and the speaker, responsive to receiving and processing the vocalized speech from the user. The voice communications module is in electronic communication with a data source.

Apparatus and methods for a USB hub connected to USB host and one or more USB devices to support the USB host and the USB devices to dynamically switch roles such that a product which initially operates as a USB device operates a USB host while a USB host supports additional operation as a USB device. Products such as smartphones, initially operating as USB devices, may dynamically switch roles to become USB hosts. Similarly USB hosts, such as PCs and in-vehicle infotainment systems, initially operating as USB hosts may dynamically support additional operation as USB devices. The USB host operates a USB device stack over a USB host stack such that the USB device stack communicates with a role-switched USB host via the root port that remains in a state acting as USB host. In addition, the USB host maintains a connection to an upstream port of the USB hub.

A unidirectional KVM device, comprising: a device emulator connected to a keyboard interface and a pointing device interface of a computer, and a video connection connected to a video interface from said computer, said device emulator receives keyboard and pointing device communication signals through an optical fiber and transmits keyboard signals and pointing device signals to said keyboard interface and pointing device interface, said video connection receives video stream from video interface of said computer and transmits said video streaming through an optical fiber, a controller-and-host-emulator coupled with a keyboard interface and a pointing device interface; a serial-to-HDMI unit receives the video stream from said computer through said optical fiber, and transmits said serial video stream via said video interface to the user display device, said controller-and-host-emulator receives keyboard and pointing device communication signals, and transmit said communication signals to said device emulator through an optical fiber.

A virtualization acceleration device is deployed for a physical machine, and a virtualized peripheral controller for the physical machine is implemented on the virtualization acceleration device, so that the physical machine may call the virtualized peripheral controller to execute an operation related to an external device. In this way, a VNC server is deployed on the virtualization acceleration device instead of on the physical machine; the virtualization acceleration device cooperates with a remote control device, and the virtualized peripheral controller remotely controls the physical machine, thereby reducing resources of the physical machine consumed in the remote interaction process, which in turns improves the physical machine performance.
