20090038623 | INDUCTIVE POWER TRANSFER SYSTEM FOR PALATAL IMPLANT - An inductive power transfer system associated with an airway implant device is disclosed. A non-implanted portion of the system comprises a mouthpiece or retainer. The mouthpiece includes a power transfer circuit and a power source. The power transfer circuit includes a receive circuit configured to receive a first inductive power transfer from a charging device and to deliver a charging current to the power source. The power transfer circuit also includes a transmit circuit coupled to the power source. The transmit circuit is configured to provide a second inductive power transfer from the mouthpiece to the airway implant. Some embodiments of the non-implanted portion include a charge controller and a lithium polymer battery. Some embodiments of the charging device include a microcontroller for controlling operation of the charging device based on a proximity of the mouthpiece. | 02-12-2009 |
20090069866 | IMPLANT TESTER - An implant testing device and a method of detecting an airway implant are disclosed. The testing device detects the presence of the implant within a patient's body and can be used to determine its location. The testing device also provides an indication of proper function of the implant electronics. A detector circuit of the testing device generates an output signal representative of proximity of the airway implant. A processing circuit receives the output signal and determines proximity of the implant based on one or more detection thresholds. The processing circuit also provides a visual and/or audible alert. In some embodiments, the processing circuit varies the flash rate of one or more light emitting diodes and/or the pitch of an alert tone based on proximity of the implant. Various embodiments of the testing device are adapted for handheld use and can include a handle, elongated portion, and detector element. | 03-12-2009 |
20100198305 | DETECTION OF IMPLANT FUNCTIONALITY - Techniques are disclosed for detecting a functionality of a medical device implanted within the human body. A testing method includes delivering power to and measuring an electrical response of ion exchange polymer metal composite (IPMC) material that is part of the implant device in a first testing interval. Power can be transmitted at radio frequencies which penetrate tissue such that direct contact with the implant device is not required. Following the first testing interval, the implant can be powered continuously for a predetermined time. The implant can be powered in a second testing interval and the electrical response can again be measured. A functionality of the implant device can be detected based on the electrical response in the first and second testing intervals. The testing method can be practiced in connection with a handheld device, a retainer, or other suitable apparatus. | 08-05-2010 |

20080285598 | PHASE ROTATOR FOR DELAY LOCKED LOOP BASED SERDES - An apparatus comprising a first multiplexer circuit (MUX) to receive a plurality of clock phase signals at a corresponding plurality of MUX inputs and to output a first clock signal and a second clock signal that are out of phase with each other, a phase delay circuit to receive the output of the first MUX and to generate adjusted first and second clock signals that have reduced phase error with respect to detected edges of incoming data, an output MUX to receive the adjusted first and second clock signals and to output a recovered clock signal, and a control circuit coupled to output MUX select inputs. The control circuit includes logic circuitry to select the first adjusted clock signal as the recovered clock signal and to select the second adjusted clock signal as the recovered clock signal when the first adjusted clock signal nears a phase limit due to drift of the detected data edges. Other devices and methods are disclosed. | 11-20-2008 |
