Abstract: The disclosed embodiments relate to a system for transmitting data from a sensor to a host. During operation, the system periodically samples data at the sensor with reference to a sensor clock. Next, the system uses the sensor clock to transmit the data from the sensor to the host, wherein the host operates with reference to a host clock, which is different than the sensor clock. During the transmission process, the system embeds a clock in the data, wherein the embedded clock can be extracted at the host and used to receive the transmitted data. In some embodiments, transmitting the data involves using voltage-mode signaling. In other embodiments, transmitting the data involves using current-mode signaling.

Abstract: An adapter for providing connectivity between a host connector of a host device and an accessory connector of an accessory that is incompatible with the host connector is described. The adapter can include a host interface connector that is compatible with the host connector, and an accessory interface connector that is compatible with the accessory connector of the accessory. The adapter may further include an identification module that can provide adapter identification information to a host device connected to the host interface connector, and may also include an authentication module that can authenticate an accessory connected to the accessory interface connector.

Abstract: An adapter for connecting an accessory to a portable electronic device includes a first connector compatible with a connector of the portable electronic device and a second connector compatible with a connector of the accessory. The connectors of the accessory and the portable electronic device are otherwise incompatible with each other. The adapter provides two levels of authentication. First, the adapter authenticates itself to the portable electronic device. If this first authentication is successful, then the adapter authenticates the accessory to the adapter.
