Patent Images
1. A system for measuring a physiological condition of a patient, comprising:
- a wireless sensor configured to generate a physiological signal of a patient, wherein the wireless sensor comprises a power module comprising a power source configured to power the wireless sensor and comprising a charging control circuit configured to compare a level of charge of the power source to a threshold and to provide a low power indication in response to determining that the level of charge is below the threshold; and
a charging device comprising a receiving module configured to couple to the power module and comprising a power transmission module configured to recharge the power source when the power module is coupled to the receiving module.

Abstract
Methods and systems are provided for recharging a power module of a sensor (e.g., a wireless sensor). The system may include a charging station, which may receive and recharging the power module of the sensor. The charging station may be configured to recharge the power module directly or inductively. Furthermore, the charging station may be configured to recharge the power module while the power module is removed from the sensor or while the power module is operatively coupled to the sensor. Additionally, the charging station may be a component of a monitoring device, which may operate in combination with the sensor.
