  • Patent number: 5014284
    Abstract: A method and apparatus for processing electrical signals by modifying delta modulation to discrete slope delta modulation includes converting its electrical signals into compressed digital information, and representing this digital information as a sequence of slops or deltas added to the past value of the representation. For each sample period, a slope is chosen from slope tables having multiple entries and each choice is represented by a Huffman code. Signal compression occurs in two steps: first the selection of a small number of possible slopes provides compression and also the most probable slopes are represented by the shortest Huffman codes providing additional compression. Depending on the history of the slope chosen, multiple tables can be accessed with different slop entries. Two check point values are provided which code absolute output levels instead of slopes in order to facilitate recovery of the signal in the event of transmission errors.

  • Patent number: 4812724
    Abstract: A control system for an angiographic injector which precisely regulates the speed of a motor used to expel contrast media from a syringe. The control system is centered around a microprocessor which receives commands from the operator via a keyboard, and then regulates the speed of the motor by supplying drive command pulses to a circuit which integrates the difference in frequency between the command pulses and another pulse train whose frequency is proportional to actual motor speed. The control system also includes a velocity loop which uses the motor back EMF to supply an analog voltage also proportional to motor speed to a difference amplifier in a conventional velocity loop. The system is a dual loop controller where the second loop provides approximate speed control, while the first loop provides a "velocity correction" voltage required to bring the system to zero steady state speed error.

  • Patent number: 4572191
    Abstract: An externally controlled implantable electronic device for delivering a cardioverting pulse of energy to an ailing heart. A defibrillator produces a first signal when its storage device is fully charged and ready to be discharged, and a second signal when a predetermined characteristic of an ECG signal is detected. An actuator is provided for determining the presence of both of these signals. If during a predetermined time period, there is a simultaneous occurrence of the first and second signals, then the defibrillator will be activated to deliver the cardioverting shock to the heart. In the absence of either of the two signals, the defibrillator will not deliver a shock.

  • Patent number: 4567883
    Abstract: A data recording arrangement for recording ECG data within the body of a patient, for transmitting the ECG data to a point external to the body of a patient, and for recovering the transmitted ECG data is disclosed. The recording arrangement employs delta modulation circuitry for delta modulating the ECG data to obtain a delta modulated digital pulse train. The digital pulse train may be stored within the body of a patient for subsequent transmission external to the body of a patient. Transmission of the data external to the body of a patient may be by a piezoelectric transducer which transmits the digital data audibly for external detection and delta demodulation. Alternatively, delta demodulation may occur within the patient's body, and the demodulated analog signal may then be transmitted by FM, using the piezoelectric transducer to provide the FM audible signal detectable by an FM demodulator external to the body.
