  • Publication number: 20220225832
    Abstract: A micro puree machine including a housing, a power shaft, a bowl assembly and a platform. The power shaft extends from the housing. The bowl assembly including at least one locking bowl element. The platform includes at least one complementary locking platform element that is configured to engage the at least one locking bowl element such that rotation of the bowl assembly relative to the platform is prevented at times the bowl assembly is positioned thereon. The platform is rotatable from a first position to a second position relative to the housing such that the platform raises the bowl assembly towards the power shaft during the rotation of the bowl assembly and platform. The raising of the bowl assembly facilitates connection between the power shaft and a blade assembly that is positioned in a lid assembly on the bowl assembly.

  • Publication number: 20220202248
    Abstract: A lid assembly for use with a micro puree machine including a lid, a clip mechanism, and a release mechanism. The defines an axis. The clip mechanism is movable between an inward position and an outward position relative to the axis of the lid. The release mechanism is positionable relative to the clip mechanism between a home position and a release position and is operable to move the clip mechanism between the inward position and the outward position. At times the release mechanism is positioned toward the home position, the clip mechanism is moved toward the inward position. At times the release mechanism is positioned toward the release position, the clip mechanism is moved toward the outward position. The clip lever is operable to cause the clip mechanism to engage with or disengage from the blade assembly during installation and removal of bowl assembly from a micro puree machine.

  • Publication number: 20220202250
    Abstract: The present invention relates to a micro puree machine that includes a blade assembly, a lid assembly, and a clip mechanism. The blade assembly has a central support hub, a blade, and an undercut. The lid assembly is configured to cooperate with a bowl assembly and includes a lid and a clip mechanism. The clip mechanism is movable between a first position and a second position and cooperates with the undercut at times the clip mechanism is the in the first position. The blade assembly is retained in the lid assembly at times the clip mechanism is in or near the first position, and the blade assembly is disengaged from the undercut and removable from the lid assembly at times the clip mechanism is in or near the second position.

  • Patent number: 6490478
    Abstract: A system and method based on electrocardiogram (ECG) complexity analysis for real-time detecting shockable ventricular fibrillation (VF) and ventricular tachycardia (VT), and discriminating them from non-shockable tachyarrhythmia (e.g. supraventricular tachycardia (SVT) and atrial fibrillation (AF)) and high-frequency noise. In the disclosed invention, complexity measure CM (0 to 100), quantitatively characterizing the complexity nature of the non-linear dynamics underlying cardiac arrhythmia, is extracted from the sensed patient ECG signal using ECG complexity analysis. From the calculated complexity measure, by three thresholds (low complexity threshold (LCT), mediate complexity threshold (MCT), and high complexity threshold (HCT)), different kinds of tachyarrhythmia (i.e.

  • Patent number: 6480734
    Abstract: A cardiac monitor is provided that monitors the condition of the heart of a cardiac patient and generates signals indicating one of several conditions, such as supraventricular tachycardia, ventricular tachycardia and ventricular fibrillation. In order to generate these signals, the ECG from the patient is analyzed to determine a cardiac interval and heart rate, as well as a waveform factor and a waveform factor irregularity. The waveform factor is derived from the average of the ECG amplitudes during a cardiac interval and the peak value of the ECG during the same interval. Preferably, a running average is calculated over several intervals. This waveform factor is then used to detect shockable ventricular arrhythmia. The waveform factor irregularity is indicative of the variability of the waveform factor and is used to differentiate between ventricular tachycardia and ventricular defibrillation.
