  • Publication number: 20250016086
    Abstract: This disclosure describes systems, methods, and devices related to automated Ethernet testing for a communications network. A device may identify a service identifier of a service provided by the communications network to a customer; identify, based on the service identifier, a circuit comprising devices and interfaces used to provide the service; determine that the devices include a first device including an Ethernet transport line; present an Ethernet test panel showing an indication of the first device; receive, from the Ethernet test panel, a user request from a customer of the circuit to test the circuit; initiate a live Ethernet diagnostic on the circuit in response to the user request; receive, based on the live Ethernet diagnostic, performance metrics of the circuit; detect an occurrence of an event in the circuit; and present, based on the occurrence of the event, a notification of the event to the customer.

  • Publication number: 20050121050
    Abstract: An electric iron for straightening ladies hair, capable of producing anion and ozone, has an electron generator embedded on one of the handle of ceramic plate heating electric iron. Electrons generated from the inside of the ion generator meet air at the end of two different cathode lines, which are ended with sharp carbon steel needle, and generate anions and ozone. Pluralities of small holes developed along the heater cases enables even distribution of the anions along the heating blades. The ion generator of the current application is so powerful that the concentration of anions in the air is about 1,000,000 each/cubic centimeters even when measured 15 cm apart from the heating blades. Such long range distribution enables pretreatment of the user's hair with anion and ozone before the heating blades touch them.

  • Publication number: 20050056631
    Abstract: An electric iron for straightening hair that is capable of producing anion has an electron generator embedded on one of the handles of the ceramic plates heating the electric iron. Electrons generated from the inside of the ion generator meets air at the end of the cathode line, which is equipped with plurality of thin carbon fiber filaments, and generates oxygen anion. Oxygen anion produced comes into contact with the hair and makes it smooth and silky.
