  • Patent number: 10100894
    Abstract: Extension for a cylinder of a vibration damper comprising a base and a tube portion adjoining the latter. The base and the tube portion are formed in one piece. The tube portion has a circumferential bend pleat with respect to the base.
    Type: Grant

  • Patent number: 8065754
    Abstract: The pole plunger includes a main shaft having an upper disc secured to an upper end and a lower disc secured to a lower end. The lower disc has a radius greater than that of the upper disc, allowing the user to select the appropriately sized disc which matches the radius of a drain pipe to be plunged. Additionally, a handle portion may be secured to the main shaft, extending in a direction orthogonal thereto, providing the user with a handle to grip during the plunging process. The handle portion further has a handle disc secured to its free end, with the handle disc having a radius between that of the upper and lower discs, providing the user with a third size disc for plunging of the drain pipe.

  • Publication number: 20050149135
    Abstract: A system and method for selectively treating a ventricular tachycardia based on sensed atrial and ventricular intervals from the patient's heart. A detection window of the ten most recent atrial and ventricular intervals are analyzed for the occurrence of either tachycardia or fibrillation. When a majority of the sensed intervals are satisfied, the apparatus starts a duration time interval. Ventricular intervals and atrial intervals are compare, ventricular interval greater than the atrial interval by a bias factor the system delivers tachycardia therapy to the heart. Alternatively, the method withholds tachycardia therapy to the heart when the atrial rate is classified as atrial fibrillation and the ventricular response is unstable.

  • Patent number: 5824018
    Abstract: A method and apparatus for generating a multiphasic defibrillation/cardioversion waveform as well as a multiphasic fibrillation inducing pulse train. The multiphasic fibrillation inducing waveform being applied to the same electrodes as the defibrillation/cardioversion waveform.

  • Patent number: 5269300
    Abstract: A method and apparatus for automatically adjusting the sensing threshold in an automatic implantable cardioverter/defibrillator with pacing capability. Fixed sensitivity is used for a specified interval following each pacing pulse and automatic sensitivity adjustment is used when spontaneous cardiac depolarization is detected. For spontaneous cardiac depolarization, the sensing threshold is automatically adjusted to a value proportional to the amplitude of the sensed cardiac signal. The sensing threshold continuously decreases between sensed cardiac depolarizations, ensuring that a lower level cardiac signal will be detected. When a pacing pulse is delivered, the sensing threshold is set to a fixed value and held at that value for a predetermined period of time such that the sensing threshold will not be affected by the cardiac response evoked by the pacing pulse. At the end of the predetermined period of time, the sensing threshold is decreased as it would following a spontaneous cardiac depolarization.
