  • Patent number: 6638232
    Abstract: A method is delineated for detecting and locating coronary artery and heart disease comprising the steps of obtaining electrocardiograph (EKG) signals from a patient, modifying the EKG signals, and establishing a base value for use in evaluating modified EKG signals. The step of modifying includes the steps of amplifying the EKG signals, digitizing amplified EKG signals, mathematically modifying the amplified and digitized EKG signals to obtain 12 lead signals in the time domain, and converting the 12 lead signals into power spectrum signals in the frequency domain. The base value is obtained by taking a patient's resting heart rate in beats per minute, converting it to beats per second, and multiplying by a scaling quantity between approximately 3 and 7, inclusively. Then, a first area is calculated by integrating a selected one of the power spectrum signals from zero Hertz to the base value.

  • Patent number: 6575781
    Abstract: A power cord securing device is installed within a housing of an electrical appliance for securing a power cord. The power cord securing device includes a rotatable plate having a first part for being wound by the power cord, and a resilience element having a first terminal and a second terminal respectively connected to a second part and a third part of the rotatable plate. When the power cord is stretched, the rotatable plate is forced to rotate in a first direction and allow the resilience element to result in an counterforce, and when the counterforce is relieved, the rotatable plate rotates in a second direction opposite to the first direction.

  • Patent number: 6533575
    Abstract: The invention concerns a piezo lighter incorporating a child safety mechanism. The mechanism relates to an activation button and a flipper, which is either pivotally secured or integrally formed with the activation button. The safety mechanism includes a stopper on the activation button, which limits the downward movement of the activation button. The activation button translates downward sufficiently to operate the fuel-release lever opening the fuel-discharge valve. However, in order to activate the piezoelectric unit, the flipper must also be depressed a further distance than the activation button and rotated about a button axis to generate a spark to ignite the fuel released by the fuel-release lever and fuel-discharge valve.

  • Patent number: 6468070
    Abstract: A utility lighter (1) with an ignition-resistant mechanism. The ignition-resistant function is performed by a cam mechanism (60) having a hub (61). The hub has three integral projections: the cam lever (80), the fuel-release lever (70), and the return spring (90). Integral to the cam lever is the safety button (120) which when depressed disengages the cam lever (80) from the stopper tab (110) of the trigger (100). The trigger (100) also has an inclined surface (111) below the stopper tab (110) which the cam lever (80) engages after the safety button (120) is depressed and the trigger (100) is pulled. Once the trigger (100) is pulled, the cam lever (80) moves along the inclined surface (111) rotating the cam mechanism (60). When the cam mechanism (60) is rotated the fuel-release lever (70) opens the fuel-release valve (31) allowing fuel to transfer through to the lighting rod (16).
