Methods, systems, computer-readable media, and apparatuses for obtaining at least one bodily function measurement are presented. A mobile device includes an outer body sized to be portable for user, a processor contained within the outer body, and a plurality of sensors physically coupled to the outer body. The sensors are configured to obtain a first measurement indicative of blood volume and a second measurement indicative of heart electrical activity in response to a user action. A blood pressure measurement is determined based on the first measurement and the second measurement. The sensors also include electrodes where a portion of a user's body positioned between the electrodes completes a circuit and a measurement to provide at least one measure of impedance associated with the user's body. A hydration level measurement is determined based on the measure of impedance.

System and method for obtaining bodily function measurements using a mobile device

Systems, methods and apparatus are described that offer improved performance of a sensor bus. A first command is transmitted to devices coupled to a serial bus operated in a first mode in accordance with a first protocol to cause the serial bus to be operated in a second mode. After communicating in accordance with a second protocol while the serial bus is operated in the second mode, a second command is transmitted to the plurality of devices in accordance with the first protocol to terminate the second mode. In the second mode, extra symbols inserted into a sequence of symbols transmitted on the serial bus prevent the occurrence of an unintended signaling state on the serial bus. Pulses transmitted on a wire of the serial bus in the second mode may have their duration limited such that a filter of a second device suppresses the limited-duration pulses.

Multi-protocol dynamic address allocation

Sensors global bus

Systems, methods and apparatus are described that offer improved performance of a sensor bus. A method includes transmitting a first command on a serial bus while operating in a first mode of operation, exchanging first data with the first device in accordance with a second protocol associated with the second mode of operation, and exchanging second data with the first device in accordance with the second protocol after the first period of time. The first command may be transmitted in accordance with a first protocol to cause a first device to operate in a second mode of operation. The first device may be idle for a first period of time after the first data has been exchanged.

In one embodiment, a method for refilling a used ink cartridge includes determining a quantity of ink remaining in an ink holding chamber in the cartridge, determining a desired quantity of ink to refill the chamber based on a difference between a capacity of the chamber and the quantity of ink remaining in the chamber, and refilling the chamber with the desired quantity of ink. In another embodiment, a method for refilling a used ink cartridge includes introducing ink into an ink holding chamber in the cartridge, simultaneously with introducing ink into the chamber, monitoring the level of ink in the chamber, and ending the introduction of ink into the chamber when the level of ink in the chamber reaches a desired level.
