1. A sensor comprising:
- a housing configured to fit about a tissue of a patient;
one or more emitters disposed on the housing configured to direct light through the tissue of the patient;
one or more detectors disposed on the housing configured to detect light from the one or more emitters after the light has passed through the tissue of the patient and to convert the detected light to an electrical signal;
a rechargeable battery encapsulated in the housing and adapted to provide power to the one or more emitters and the one or more detectors; and
an inductive coil encapsulated in the housing and electrically coupled to the rechargeable battery, wherein the inductive coil is operable to inductively receive electrical power from a second inductive coil and is operable to supply charging power to the rechargeable battery.

12. A system comprising:
-
a sensor comprising; a housing configured to fit about a tissue of a patient; an emitter disposed on the housing configured to direct light through the tissue of the patient; a detector disposed on the housing configured to detect light from the emitter after the light has passed through the tissue of the patient and to convert the detected light to an electrical signal; an analog-to-digital converter encapsulated in the housing and adapted to receive and convert the electrical signal into a digital detector signal; a rechargeable battery encapsulated in the housing and adapted to provide power to the emitter and the detector; an inductive coil encapsulated in the housing and electrically coupled to the rechargeable battery, wherein the inductive coil is operable to inductively receive electrical power from a second inductive coil and is operable to supply charging power to the rechargeable battery; and a monitor comprising a processor configured to receive the digital detector signal from the sensor and calculate a physiological parameter based at least in part on the received digital detector signal. - View Dependent Claims (13, 14, 15, 16, 17)
