  • Patent number: 6516194
    Abstract: The invention is a Roaming Solution network system, the system including a Roaming Server, a National Location Register, and an 800 number Remote Switching Unit. The system is integrated with a standard SS7 type telecommunications network and further coupled to an account based billing and call control platform that allows registered wireless credit limited subscribers to place and receive calls when roaming outside of their Home Provider's network. The invention verifies that the wireless subscriber's account balance is sufficient to place or receive the call, translates the account balance into talk minutes, and monitors the call for talk duration. The Roaming Solution network system is further operable such that if the wireless subscriber exceeds the available account balance, the system tears down the call in the first negative minute and immediately decrements the wireless subscriber's account.

  • Patent number: 6516225
    Abstract: The system and method discriminates P-waves or other electrical events originating in the atria from R-waves or other electrical events originating in the ventricles. In one example, far-field R-waves in the atria are distinguished from true P-waves using both a post-ventricular atrial blanking (PVAB) interval and a separate pre-ventricular blanking interval (pre-VAB) interval. Insofar as the pre-VAB interval is concerned, upon detection of a P-wave in the atria, the implantable medical device begins tracking a pre-VAB interval. If an R-wave is then detected in the ventricles during the pre-VAB interval, the P-wave is rejected as being a far-field R-wave. A PVAB interval may also be employed to filter out any P-waves detected in the atria immediately following detection of an R-wave in the ventricles. In another example, far-field R-waves are distinguished from true P-waves using template matching. P-waves detected in the atria are compared against a template representative of true P-waves.

  • Patent number: 6516227
    Abstract: A spinal cord stimulation (SCS) system provides multiple stimulation channels, each capable of producing up to 10 mA of current into a 1 K&OHgr; load. The SCS system further includes a replenishable power source, e.g., a rechargeable battery, that requires only an occasional recharge, and offers a life of at least 10 years at typical settings. Each of the multiple stimulus channels of the system may be combined with other channels to deliver more than 10 mA of current. Additionally, the SCS system has the capability to stimulate simultaneously on all available channels. Each channel has at least two outputs (one positive and one negative) that can be mapped via a low impedance switching matrix to any electrode contact or the system case, thereby allowing a clinician to provide unique electrical stimulation fields for each current channel. Moreover, this feature, combined with multi-contact electrodes arranged in two or three dimensional arrays, allows “virtual electrodes” to be realized.

  • Patent number: 6516228
    Abstract: A totally implantable microphone for use with an implanted hearing aid comprises a cylindrical bio-inert housing having a bio-inert metallic membrane at the acoustic sensing end and a bio-inert plate containing electrical lead-throughs at the other end. The cylindrical housing is implanted in the posterior wall of the external auditory canal, with the thin auditory canal skin overlaying the microphone membrane surface. Surface features on the housing ossiointegrate it to the auditory canal bone, and a flange on the housing posterior end prevents post-operative migration into the auditory canal. A support plate beneath the membrane limits inward flexing and increases the signal-to-noise ratio. A protruding rim around the membrane perimeter acts to protect the membrane from rupturing during outward flexure. Lithographically formed wires laminated in a thin inert polymer and connected to the lead-throughs enable the overall length of the encapsulated microphone to be very short.

  • Patent number: 6516235
    Abstract: A control apparatus for controlling a control system having a sliding resistance by using a sliding mode control method determines a deviation of an actual value of a quantity of state that is to be caused to follow a target value from the target value (step 1), calculates a switching surface &sgr; from the deviation (step 2), and determines a corrected switching surface &sgr;′ by adding a carrier wave to the calculated switching surface &sgr; (step 3). The carrier wave is expressed by a periodic function, for example, a sine wave, a sawtooth pulse wave, or the like, and has finite gradients on its waveform. Then, the control apparatus outputs an amount of operation u based on the value of the corrected switching surface &sgr;′ (step 4). The amount of operation u behaves in a manner similar to that in an ordinary sliding mode control method when the switching surface &sgr; is not close to zero.
