Apparatus and method for reducing power consumption in physiological condition monitors
First Claim
1. An apparatus for monitoring a physiological condition of a person in which data about said physiological condition is stored in a memory data storage device capable of operating in (i) a high power mode when said data is being written to said memory data storage device and (ii) a low power mode when inactive, said apparatus comprising:
- a controller that is capable of (i) receiving said data from a data acquisition device and (ii) writing said data to said memory data storage device; and
a first low power buffer that is capable of storing said data from said data acquisition device in said first low power buffer until a predetermined amount of incoming data has been accumulated therein and wherein said controller transfers said accumulated predetermined amount of incoming data to said memory data storage device in a single data transfer.

Abstract
There is disclosed an apparatus and method for reducing power consumption in physiological condition monitors that use a memory data storage device that operates in a high power mode when data is being written to the memory data storage device and operates in a low power mode when inactive. The apparatus comprises: 1) a controller for receiving incoming data to be written to the memory data storage device; and 2) a first low power buffer coupled to the controller. The controller stores the incoming data in the first low power buffer until a predetermined amount of incoming data has been accumulated in the first low power buffer and transfers the accumulated predetermined amount of incoming data to the memory data storage device in a single data transfer.

19. A method of operating an apparatus for monitoring a physiological condition of a person in which data about said physiological condition is stored in a memory data storage device capable of operating in (i) a high power mode when said data is being written to said memory data storage device and (ii) a low power mode when inactive, said method of operation comprising the steps of:
-
receiving said data from a data acquisition device;
storing in a first low power buffer said data from said data acquisition device until a predetermined amount of incoming data has been accumulated; and
transferring, in response thereto, said accumulated predetermined amount of incoming data to said memory data storage device in a single data transfer.
