Abstract: A client computing device establishes a plurality of subscriptions to store published data from data sources of the client device in a subscription buffer. In response to receiving, from a remote subscription dispatcher of a host computing device, a read request for data published by data sources of the client computing device, one or more data packets including published data stored in the subscription buffer are sent to the host computing device.

Abstract: A wearable computing device includes a plurality of biometric sensors configured to determine biometric parameters of a wearer of the wearable computing device, and a plurality of modules configured to determine activity parameters of the wearer. A first module directly subscribes to receive a first biometric parameter from a first biometric sensor. A subscription of the first module to the first biometric sensor specifies activation of the first biometric sensor to provide the first biometric parameter to the first module. The first module derives a first activity parameter from the first biometric parameter. A second module indirectly subscribes to the first biometric sensor by directly subscribing to receive the first activity parameter from the first module. A subscription of the second module to the first module specifies activation of the first module to provide the first activity parameter to the second module.

Abstract: On a client computing device, a host computing device is communicated with via both a wired communication input/output (I/O) interface and a wireless communication I/O interface using a same three-stage protocol. The three-stage protocol includes a command stage, a data stage, and a status stage. During the command stage, a command packet including a command is received from the host computing device. During the data stage, one or more data packets are sent to the host computing device if the command specifies sending the one or more data packets. During the data stage, one or more data packets are received from the host computing device if the command specifies receiving the one or more data packets. During the status stage a status code indicating whether or not the command was successfully serviced by a command handler is sent to the host computing.
