Abstract: A first-aid device for detecting myocardial infarction, including a wearable textile, a first alarm detection unit, a second detection alarm unit, and a charging first-aid unit for actively detecting and alerting to myocardial infarction, instantly supplying crucial medicine, and providing a charging function. In particular, the wearable textile put on a patient carries the first alarm detection unit actively detecting myocardial infarction, the charging first-aid unit instantly provides the user medicine to alleviate painful symptom, and at the same time, the second detection alarm unit serves as a spare part while the first alarm detection unit is charged by the charging first-aid unit. As a result, the first alarm detection unit and the second detection alarm unit are alternatively used for actively and ceaselessly detecting myocardial infarction assuring first-aid for the patient.

Abstract: A system for fabricating a conductive yarn from a preformed yarn includes a yarn spool, a soaking unit, a drying unit, and a yarn winder. The yarn spool is configured for winding and unwinding of the preformed yarn. The soaking unit is configured to receive a conductive slurry and to permit passage of a leading segment of the preformed yarn so that the preformed yarn is moistened with and absorbs the conductive slurry. The drying unit is configured to subject the preformed yarn that exits the soaking unit to a heat treatment to result in the conductive yarn. The yarn winder is configured to be connected to the leading segment of the preformed yarn and is configured for winding of the conductive yarn thereon.

Abstract: A method for fabricating a conductive yarn includes the steps of: moistening a preformed yarn with a conductive slurry to prepare the preformed yarn absorbed with the conductive slurry; and drying the preformed yarn absorbed with the conductive slurry. The conductive slurry includes a conductive nanometer structure, a solvent, and a resin component. The conductive nanometer structure has an aspect ratio sufficient to permit binding of the conductive nanometer structure to the preformed yarn.

Abstract: A sock includes a sock body with a leg section and a foot section. The leg section has a cuff that defines a foot opening for insertion of a foot of a wearer. The foot section is connected to the leg section, and includes a toe section, a heel section, a sole section, and an instep section. The leg section has a back segment that faces away from the toe section and that is formed with an opening. The sock body is convertible when worn on the foot to an ankle protecting state, in which the leg section is folded down so that the cuff surrounds the foot section between the toe section and the heel section and so that the heel section extends through the opening, such that the leg section is able to provide additional protection for an ankle joint of the foot.

Abstract: A shielding sticker for use on a cellular phone against electromagnetic waves generated by the phone and having negative influence on a person using such a phone is made up of a conductive shielding screen and a conductive ring. The conductive shielding screen is woven by fiber reeled from a mixed material composed of carbon, lead and sodium. The conductive ring is made of a metal or non-mental material. The conductive shielding screen is adhered to the conductive ring by a conductive adhesive to produce an integral sticker shielding against electromagnetic waves produced by a cellular phone in operation.
