A powered, personal lifting apparatus, and specifically a lift apparatus, specially adapted for personal use in the entry into and exit from a standard bathtub. The device components are designed to strengthen and customize existing device connection cables in the area of, just adjacent to and along the entire existing cable length without dismantling such cables nor impact the usability especially in the applications where limited space exists and enhance the durability and or appearance of the existing cables, plug and power supplies. In an ultrasonic joining process, the conductors are integrally joined to each other by applying the ultrasonic vibration to the formed conductor bundle while pressing the formed conductor bundle in the predetermined direction. When the AC power supply does not fail, the first drive output signal sent from the electric actuator is selected; when the AC power supply fails, the second drive output signal generated by the motor drive circuit is selected and is sent to the AC motor of the electric actuator, via the relay connector. Then, whether the bit length of the DC factor will not be changed by embedding the obtained embedded pattern is determined. These devices and the path therebetween may be mapped in the node model.
