摘要： Medical data is communicated from a transmitter of an external unit to a receiver of an implantable medical device. The transmitter generates a preamble signal having encoded configuration data that informs the receiver of configuration settings to be used in receiving the medical data. The receiver detects the preamble and validates a modulation pattern of the preamble. Configuration data is decoded from the preamble signal and the receiver configuration is adjusted to receive the medical data.

摘要： Unscheduled wireless communication with a medical device is achieved by operating a receiver of the medical device in a series of modes. Each mode provides an increasingly selective evaluation of received RF energy. The receiver, when operating in a first mode, is capable of detecting the presence of RF energy transmitted from a communicating device. The receiver, when operating in a second mode, consumes more energy than the first mode and analyzes the RF energy to determine whether it contains the appropriate type of modulation. When operating in a third mode, the receiver consumes more energy than the second mode, and operates the full receiver to begin communication with the communicating device. The receiver opens a communication session after the RF energy has passed the evaluation by the series of modes to receive an unscheduled communication.

摘要： A receiving and filtering circuit includes an antenna, a demodulator circuit coupled to the antenna, and a digital median filter that removes high frequency content of a demodulated digital information signal to produce a filtered digital information signal corresponding to an analog data signal transmitted by a body implantable medical apparatus. The digital filter may include a multiple stage delay line coupled to a multiple tap selection device, a plurality of delay blocks coupled to a register, or a multiple stage delay line coupled to a voting unit. The voting unit produces a first binary output in response to a majority of delay line stages storing a first value, and produces a second binary output in response to a majority of delay line stages storing a second value. The digital filter may also comprise a digital signal processor. The digital filter may include a first filter block and a second filter block. The second filter block may be selectively activated or bypassed. The first filter block removes high frequency content of the digital information signal and the second filter block reduces high frequency noise at an edge of a data bit transition. A control circuit, coupled to the digital filter, provides for respective selection of data rate and frequency response characteristics of the digital filter. The digital filter may be implemented in a Field-Programmable Gate Array (FPGA) or an Application Specific Integrated Circuit (ASIC).

摘要： A body implantable medical apparatus includes circuitry for generating and transmitting a modulated analog data signal. A receiver receives and digitally demodulates the modulated analog signal. An analog-to-digital converting circuit produces an amplitude limited modulated digital signal corresponding to the modulated analog signal. The converting circuit includes an amplifier coupled to a receive antenna and a comparator having an input coupled to the amplifier and an output coupled to a digital demodulator. The digital demodulator demodulates the modulated digital signal to produce a digital information signal, such as a signal containing physiologic sensor data. The digital demodulator includes a digital delay line comprising a plurality of shift registers or, alternatively, a plurality of multiple-stage delay blocks each coupled to a tap selection device. The digital delay line includes an input coupled to an output of the converting circuit, an exclusive OR (XOR) gate having a first input coupled to an output of the digital delay line, and a conductor coupled between the input of the digital delay line and a second input of the XOR gate, such that delayed and non-delayed modulated digital signals are respectively applied to the first and second XOR gate inputs to produce a digital information signal at an output of the XOR gate. The digital demodulator may be implemented in a Field-Programmable Gate Array (FPGA), in an Application Specific Integrated Circuit (ASIC) or using a digital signal processor. A control circuit is coupled to the digital demodulator to adjust a rate at which the digital demodulator operates.
