1. A band comprising:

  • a subset of sensors;

    a controller coupled to the subset of sensors;

    an energy storage device;

    a connector configured to receive power and control signals, the connector coupled to the energy storage device;

    a power manager comprising;

    a transitory power manager configured to manage power consumption of the band during a first power mode in which no power is applied to the subset of sensors; and

    a power clock controller configured to modify a clock rate of a clock signal for application to the controller as a function of a mode of operation of the bandwherein the transitory power manager is configured further to manage the power consumption of the band during a second power mode in which power is applied to the subset of sensors, the second power mode being subsequent to the first power mode,wherein the transitory power manager is configured to detect an application of power to the connector, and, responsive to the application of power, the transitory power manager switches the band from the first power mode to the second power mode;

    wherein the first power mode and the second power mode coincide with a first interval of time and a second interval of time, respectively; and

    wherein the first interval of time comprises an amount of time during which the orientation of the band is shared with other bands in one orientation and the second interval of time comprises another amount of time during which the orientation of the band is independent of the other bands.
