SYSTEM CONNECTOR

摘要

A SYSTEM CONNECTOR IS PROVIDED TO ALLOW FOR THE COMMUNICATION OF DIGITAL SIGNALS BETWEEN TWO DEVICES (210, 220) FUNCTIONING AT DIFFERENT OPERATING VOLTAGES. THE CONNECTOR ALLOWS FOR THE INTERFACING OF THE HIGH AND LOW SIGNAL LOGIC LEVELS THROUGH THE USE OF EACH DEVICE''S OWN OPERATING VOLTAGE WITHOUT THE NEEDFOR COMPLEX SIGNAL CONVERSION OF VOLTAGE LEVELS. THE CONNECTOR MAY BE USED TO ALLOW COMMUNICATION BETWEEN MOBILE PHONES (210) AND THEIR ACCESSORIES (220). THE SYSTEM CONNECTOR MAY BE INCORPORATED INTO AN ACCESSORY OR PORTABLE DEVICE (220) ALLOWING THE SIGNAL LEVEL INTERFACING BETWEEN THE PORTABLE DEVICE AND ACCESSORY. THE SYSTEM CONNECTOR SUPPLIES A HIGH-LEVEL OR LOW-LEVEL DIGITAL SIGNAL TO A FIRST DEVICE OPERATING AT A FIRST VOLTAGE IN RESPONSE TO A CORRESPONDING HIGH-LEVEL OR LOW-LEVEL DIGITAL SIGNAL FROM A SECOND DEVICE OPERATING AT A SECONDVOLTAGE. IN ADDITION, THE SYSTEM CONNECTOR MAY ALSO PROVIDE A HIGH-LEVEL OR LOW-LEVEL DIGITAL SIGNAL FROM A SECOND DEVICE OPERATING AT A SECOND VOLTAGE IN RESPONSE TO A CORRESPONDING HIGH-LEVEL OR LOW-LEVEL DIGITAL SIGNAL FROM THE FIRST DEVICE OPERATING AT THE FIRST VOLTAGE.
