Synchronization of effects across multiple devices using local, distributed control, and eliminating the need for central direction of the effects with the associated large bandwidth required. In one embodiment, each device stores data and instructions for creating its own effects. The devices periodically communicate with a host or each other to maintain synchronization, and compensate for any drift. This approach minimizes the use of bandwidth and battery power in the devices.

Synchronization of computer peripheral effects

A computer system includes a receiver configured to pair with a set of peripheral devices and have active connections with a first subset of the peripheral devices and inactive connections with a second subset of the peripheral devices. The first and the second subsets of peripheral devices are subsets of the set of peripheral devices. If a select one of the peripheral devices in the inactive set of peripheral devices is operated, the receiver is configured to activate a connection with the select one of the peripheral devices in a latency period that is below human perception levels of the latency period.

Receiver configured to pair to multiple wireless devices

A communication protocol in a wireless network of a transceiver and a plurality of devices, in which at least one device is a bidirectional device, and in which one or more other devices can be unidirectional devices. The unidirectional device communicates with the transceiver in a unidirectional mode from the device to the transceiver and the bidirectional device communicates with the transceiver either in a bidirectional mode or in an unidirectional mode from the device to the transceiver. The communication protocol is configured to determine which transmission mode is to be used for each device. Various techniques are provided in order to optimize the time and energy spent to transmit information from one peer to the other.

Communication protocol for networked devices

A computerized method provides for a computer to interact with peripheral devices where a complete set of control functions of the peripheral devices are operable on the computer. The method includes receiving by a computer from a receiver coupled to the computer an enumerator report having a peripheral device report and a device index included in a set of device indices. The peripheral device report is sent from a select peripheral device to the receiver. The method further includes determining by the computer the device index in the enumerator report. The method further includes routing by the computer the peripheral device report to a device driver associated with the device index. The device driver is configured to provide a complete set of operating function for a peripheral device associated with the device driver. The computer executes a command function from the peripheral device report issued by the select peripheral device.

A wireless communication system for a computer includes a hub coupled to the computer. The hub includes a first module and a second module, the first module configured to receive commands from one or more wireless input devices, the second module configured to control the first module and interface with the computer. A first wireless input device is configured to be linked to the hub to input a first command to the computer via the hub. A second wireless input device is configured to be linked to the hub to input a second command to the computer via the hub. The hub is configured to support a first operational mode and a second operational mode. The first module transmits the first and second commands received from the first and second input devices to the computer via the second module during the first operational mode. The first module transmits the first and second commands received from the first and second input devices to the computer without using the second module as an interface to the computer during the second operational mode.
