A method and apparatus for improving hearing by preventing acoustic feedback from the ossicular chain into a middle ear-implanted microphone of an implantable hearing assistance system. An audit server invokes the heterogeneous information sources via a uniform communications interface to gather information about the network, and converts the information gathered by the information sources into a normalized data format such as, for example, into XML. Related processes and systems for supplying food energy data to a requester and supplying meal plan data to a consumer are also provided. The rotary member is pivotally connected to the case between a first position and a second position. The present invention involves the partial incorporation of the PKI based mechanisms present in the Rights Object Acquisition Protocol suite of OMA DRMv2 model into the SyncML protocol, resulting in security enhancements for SyncML.
