Latest Patents

One of Fisher's notable inventions is the "Grounded Isolation System." This system and method are designed for isolating and grounding a load device, ensuring that grounding only occurs after the voltage(s) on the load device have been reduced to acceptable levels. The system includes power and grounding contacts, a sensing device, and a control device. The power contact determines whether a power line is coupled to a terminal of the load, while the grounding contact determines whether the terminal is coupled to ground. Upon receiving a signal, the control device decouples the terminal from the power line and, once the sensing device confirms that a condition has been met, the control device grounds the terminal and illuminates a system indication light.

Another significant patent by Fisher is also titled "Grounded Isolation System." This invention focuses on electrically isolating and indicating the electrical isolation of a machine. It employs a plurality of relays that cooperate to ground voltage input lines to the machine when electrical isolation is selected. This ensures that no power is provided to the machine during operator access, enhancing safety.
