Abstract: A system and method for representing multiple security groups as a single data object are provided. With the system and method, a complex group object is created that consists of a group set value and a mask value. The complex group object represents a plurality of groups by the group set value. The mask value is used to apply to group identifiers received during an authentication process to generate a value that is compared against the group set value to determine if the group identifiers are part of the complex group. For example, in a first step of authorization processing, the group identifier received in an authorization request is bit-wise AND'd with the mask value for the complex group data object. In a second step, the masked group identifier from the received request is compared to the group set value of the complex group object. Such comparison may take the form of masking the group set value and comparing the masked group set value to the masked group identifier from the received request, for example. If the two values match, then access is granted. If the two values do not match, then access is denied.

Abstract: A method, device and system for responsive load management using frequency regulation credits. The method includes using an AC frequency measuring device, measuring a current AC frequency on an AC power line; using a power consumption measuring device, measuring a current power consumption on the AC power line over a period of time equal to a sampling interval; calculating a power consumption moving average of a last N power current power consumptions measured, where N is a positive integer greater than 1; generating credits or debits based on the current power consumption, the current AC frequency and the power consumption moving average; adding the credits or debits to a frequency regulation credit; and for each next sampling interval repeating measuring the current AC frequency, measuring current power consumption, calculating the power consumption moving average, generating the credits or debits, and adding the credits or debits to the frequency regulation credit.
