    • An integrated circuit dynamically compensates for circuit aging by measuring the aging with an aging sensor. The aging sensor uses the same circuit to measure circuit speeds in both aged and un- aged conditions. An example aging sensor includes two delay lines (411, 412). The delay lines (411, 412) are controlled to be in a static aging state or the delay lines (411, 412) are coupled to form a ring oscillator that can operate in an aged state where the frequency is slowed by aging or in an un-aged state where the frequency is not slowed by aging. The integrated circuit uses the aging measurements for dynamic voltage and frequency scaling. The dynamic voltage and frequency scaling uses a table of operating frequencies and corresponding voltage that is periodically updated based on the aging measurements. The integrated circuit use information about the relationship between the aging measurements and circuit performance to update the table.

    • A line frequency monitoring and load shedding control apparatus is placed in or closely coupled to a power load and monitors the line frequency of the alternating current electric power source supplying the power load. When a decrease in line frequency is detected, this line frequency monitoring and load shedding control apparatus may interrupt certain portions of the power load, thereby allowing the power source frequency to stabilize. Subsequently, the line frequency monitoring and load shedding control apparatus makes a determination to return operation of the load that was shed to a normal state of operation as the power line frequency recovers to a normal operating frequency. Fixed time delays, e.g., adjustable, programmable, etc., and/or pseudo random time delays may be incorporated to sequentially reconnect the loads back onto the power source, thereby preventing the loads previously shed from being reconnected all at the same time.

    • The invention relates to a method for determining the chance of a disturbance-free operation of a frequency converter (2) connected to a feeding network (18). According to the invention, during the operation of said frequency converter (2), an intermediate circuit voltage (U ZK ) is continuously measured and a network-side intermediate circuit current (i ZKnetz ) is continuously determined; these measuring quantities are compared with pre-determined operating values of the frequency converter (2), and quantities which are higher or lower than said values are respectively stored; and the frequency (H ij ) of said higher and lower measuring quantities is determined and converted into a characteristic number for the quality of the feeding network (18). As said characteristic number decreases, the chance of a disturbance-free operation of the frequency converter (2) increases. In this way, a frequency converter (2) is able to detect the risk of appliance disturbance or failure as a result of network disturbances before the operation is interrupted.
