  • Publication number: 20150094755
    Abstract: A non-invasive cerebral perfusion increasing device including four cuffing pad units and a control unit which is connected to the cuffing pad units and is equipped with a blood pressure sensing module and a compression control module. In the non-invasive cerebral perfusion increasing device each cuffing pad unit respectively includes a compression pad, a compression control member and a blood pressure sensing member. The blood pressure sensing module uses the blood pressure sensing members to sense the systolic blood pressure values of the portions of each of the limbs where they are attached and the compression control module controls the degree of compression of each compression pad by controlling the compression control member to a setting desired by the user based on the sensed blood pressure value, such that the blood flow applied to the limbs is blocked and, indirectly, cerebral perfusion is increased.

  • Publication number: 20080140979
    Abstract: Provided is a method of allocating a stack in a multi-threaded sensor operating system environment. The method dynamically allocates as much stack space as is required by a thread, thereby enabling efficient use of stack space. The method includes the steps of: whenever a function is called while a thread is performing an operation, dynamically allocating a stack space to be used by the called function; and when execution of the function is finished, returning the allocated stack space.
