Methods and systems for performing wireless communication are presented. In one example, a wireless peripheral device comprises a wireless transceiver configured to receive and transmit data over a primary channel, an optical sensor configured to receive data over an out-of-band channel, and one or more processors configured to: receive, via the wireless transceiver and over the primary channel, wireless signals including first key data from a second device; receive, via the optical sensor, optical signals including verification data from the second device; verify the first key data based on the verification data; and responsive to verifying the first key data based on the verification data, generate a digital security key based on the first key data, the digital security key used for following data transmission between the wireless peripheral device and the second device via the wireless transceiver.

Secure wireless communication with peripheral device

In some embodiments, a transceiver is configured to wirelessly transfer data between a host computing device and a plurality of peripheral devices over a communication path using a communication data construct sent by the transceiver comprising a plurality of packet structures forming a communication protocol for communicating peripheral device data (HID or audio data) between the host device and the plurality of peripheral devices. Each of the packet structures of the plurality of packet structures can include a single destination address configured to identify which of the plurality of peripheral devices will receive peripheral device data from the host computing device in the present packet structure and which of the plurality of computer peripheral devices will not receive peripheral device data from the host computing device in a present packet structure; and a data field configured to contain peripheral operational data for each of the plurality of peripheral devices.

Wireless communication protocol with peripheral devices

In some embodiments a transceiver is configured to wirelessly transfer data between a host computing device and one or more peripheral devices over a communication path using a communication data construct comprising a packet structure arranged in a repetitive communication structure. The repetitive communication structure can include a transmit time window within which the host transmits data to the one or more connected peripheral devices and a receive time window within which the host receives data from the one or more connected peripheral devices. A duration of the receive time window is set based on a predetermined communication report rate between the host computing device and the one or more connected peripheral devices. A new peripheral device is added as a connected peripheral device when the new peripheral device transmits a request to the host to be added as a connected peripheral device and the receive time window has time available to add the new peripheral device.

Wireless communication protocol having a predetermined report rate

A computer-implemented method includes sending a broadcast over a network requesting a response from other host computers on the network that are also communicatively paired with the input device, receiving a broadcasted response from a second host computer on the network indicating that it is communicatively paired with the input device, establishing a communicative connection with the second host computer via the network and automatically reestablishing the connection with the second host computer when the second host computer disconnects and reconnects to the network. In response to an edge-detect event, sending a control signal to switch the communicative pairing of the input device from the first host computer to the second host computer.

Automatic multi-host discovery in a flow-enabled system

Embodiments of the present invention provide a method and system of switching a wireless connection between a plurality of input devices and a first host device to at least a second host device. Embodiments of the invention are directed to systems and methods for switching multiple, independently connected data input devices from a first host computing device to a second host computing device together based on a single command or operation.

Input device with multi-host switching

Embodiments of the invention are directed to input devices configured for use with computing devices. The present invention relates to methods and devices for establishing, maintaining and managing, wireless connections between an input device and one or more host computing devices running one of a plurality of operating systems. The input device may be configured to analyze data received from the host computing devices to automatically or manually determine an operating system running on the host computing devices and configure the input device for proper functionality with the determined operating system.

Universal input device

Embodiments of the present invention provide a method of establishing a wireless connection between a data input device and a host computing device. More specifically, the embodiments of the present invention relate to methods and systems for using a single input device (e.g., keyboard, mouse, or touchpad devices) with multiple host computing devices that may be running different operating systems, and efficiently switching the data protocols used to transmit HID data between the input device and the multiple host computing devices without requiring user interaction.

Multi-operating system input device

Embodiments of the invention are directed to control devices, such as human interface devices, configured for use with a tablet computer. More specifically, the present invention relates to methods and system for discriminating between the interactions of a handheld device, touch of one or more of the user's finger(s) and interaction with appendages of the user on a touch-screen tablet computer. The methods described herein may include discriminating between the interaction of the handheld device, the user's finger(s) and an appendage of the user so that the collected information can be used to control some aspect of the hardware or software running on the touch-screen tablet computer.
