摘要： An improved implantable medical device system having dual coils in one of the devices in the system is disclosed. The dual coils are used preferably in an external device such as an external controller or an external charger. The dual coils are wrapped around axes that are preferably orthogonal, although other non- zero angles could be used as well. When used to transmit, the two coils are driven (for example, with FSK-modulated data when the transmitting data) out of phase, preferably at 90 degrees out of phase. This produces a magnetic field which rotates, and which reduces nulls in the coupling between the external device and the receiving coil within the implanted device. Moreover, implementation of the dual coils to transmit requires no change in the receiver circuitry of the implanted device. Should the device with dual coils also receive transmissions from the other device (e.g., the implanted device), the two coils are used in conjunction with optional receiver circuitry which likewise phase shifts the received modulated data signals from each coil and presents their sum to typical demodulation circuitry.
摘要翻译：公开了一种在系统中的一个装置中具有双线圈的改进的可植入医疗装置系统。双线圈优选地用于诸如外部控制器或外部充电器的外部设备中。双线圈缠绕在优选正交的轴上，尽管也可以使用其他非零角度。当用于发送时，两个线圈被驱动（例如，当发送数据时具有FSK调制数据）异相，优选地相差90度。这产生了旋转的磁场，并且在植入的装置内的外部装置和接收线圈之间的耦合中减少零点。此外，实施双线圈以进行传输不需要在植入装置的接收器电路中改变。如果具有双线圈的设备也接收来自另一设备（例如，植入设备）的传输，则两个线圈与可选的接收机电路结合使用，其同样地相移来自每个线圈的接收的调制数据信号，并将它们的和表示为典型解调电路。

摘要： Receiver and demodulation circuitry for an external controller for an implantable medical device is disclosed. The circuitry comprises two high Quality-factor band pass filters (BFPs) connected in series. Each BFP is tuned to a different center frequency, such that these center frequencies are outside the band of frequencies transmitted form the IMD. The resulting frequency response is suitably wide to receive the band without attenuation, but sharply rejects noise outside of the band. The resulting filtered signal is input to a comparator to produce a square wave of the filtered signal, which maintains the frequencies of the received signal and is suitable for input to a digital input of a microcontroller in the external controller. Demodulation of the square wave occurs in the microcontroller, and involves assessing the time between transitions in the square wave. These transmission timings are compared to expected transition times for the logic states in the transmitted data. The results of these comparisons are stored and filtered to remove noise and to recover the transmitted data.

摘要： A charging system for an Implantable Medical Device (IMD) is disclosed having a charging coil and one or more sense coils. The charging coil and one or more sense coils are preferably housed in a charging coil assembly coupled to an electronics module by a cable. The charging coil is preferably a wire winding, while the one or more sense coils are concentric with the charging coil and preferably formed in one or more traces of a circuit board. One or more voltages induced on the one or more sense coils can be used to determine the resonant frequency of the charging coil/IMD coupled system. The determined resonant frequency can then be used to determine the position of the charging coil relative to the IMD. The magnetic field produced from the charging coil may also be driven at the resonant frequency to optimize power transfer to the IMD.

摘要： Receiver and digital demodulation circuitry for an external controller for communicating with an implantable medical device (IMD) is disclosed. A Digital Signal Processor (DSP) is used to sample received analog data transmitted from the IMD at a lower rate than would otherwise be required for the frequency components in the transmitted data by the Nyquist sampling criteria. To allow for this reduced sampling rate, the incoming data is shifted to a lower intermediate frequency using a switching circuit. The switching circuit receives a clock signal, which is preferably but not necessarily the same clock signal used by the DSP to sample the data. The switching circuit multiplies the received data with the clock signal to produce lower intermediate frequencies, which can then be adequately sampled at the DSP at the reduced sampling rate per the Nyquist sampling criteria.

摘要： A method and system for pairing a remote control transmitter and receiver includes associating an identification (ID) code with the transmitter. The transmitter includes a light generator for generating a light signal in order to perform a primary function which is visually detectable by a human operator. The light generator may be a laser pointer or a status indicator LED. The light generator is modulated to encode the identification code onto the light signal while the light generator is performing the primary function. The receiver includes a light signal detector such as an LED for receiving the light signal from the light generator. The receiver associates itself with the ID code contained in the light signal in order to pair the receiver with the transmitter. By being paired with the transmitter, the receiver acts upon transmitted command signals received from the transmitter.
