Title: Non-invasive method and apparatus for tissue detection
Inventor: CORY PHILIP C
IPC: A61B5/05
Filed: 2002-06-13
Abstract: An apparatus and method for non-invasively determining tissue structure by applying a periodic waveform to an external or internal body part. A microprocessor (16) provides instruction to a waveform generator (8) to generate a plurality of different periodic waveforms to at least one samplin g electrode (12) electrically connected to at least on return electrode (14) through the tissue structure. The impedance of the tissue structures are selectively determined for each generated waveform. After determining a plurality of impedance measurements various calculations are performed, including determining a ratio of impedance change and the applied current change. The apparatus may apply the same waveform to all sampling electrodes (12) simultaneously, or apply the waveform to a few as one sampling electrod e (12) at a time. The apparatus may also simultaneously apply a plurality of waveforms to a plurality of electrodes to maintain the same current waveform on each sampling electrode (12).

Inventor: KASAMSETTY RAVIKANTH
IPC: G06F9/44
Filed: 2003-04-28
Abstract: A method for providing memory management for objects is described.  Specifically, techniques are described for providing common memory management code to objects that are instances of different classes and for releasing a memory management subtree that starts with a particular object in the memory management tree. A memory management template provides common pre-processor memory management code. A specialized version of the memory management template is used to create a specialized template subclass. When a memory management operator of an object that is an instance of the specialized template subclass is invoked the common memory management code in the specialized template is executed. Memory is associated with each object in a hierarchical tree. Data for the memory is maintained that reflects the hierarchical tree relationship between the objects. A subtree and the associated memory can be released without an application program tracking the relationships.
