Abstract: Accordingly, a digital logic circuit in the form of a finite state machine (FSM) is implemented in a semiconductor structure such as complementary metal oxide silicon (CMOS) with reduced power dissipation by determining transition probabilities for transitions between states in the FSM, producing a constraint matrix to identify constraints to producing a minimum area implementation consistent with minimum power dissipation, constructing one or more state chains having transitions with highest probability and implementing each of these state chains in order of probability to achieve the implementation of the FSM having minimum power dissipation.
Abstract: A system and method are provided for monitoring network performance in a network controlled by a communication access method. The communication access method is modified to communicate with a network performance monitor so that the communication access method will monitor its internal processing for information units for a predetermined resource upon request of the network performance monitor. The communication access method time stamps each inbound and outbound information unit for the predetermined resource and sends formatted data regarding each information unit, including the time stamp data, to a predetermined exit from the communication access method. The network performance monitor obtains the formatted data from the performance exit and processes the formatted data to determine network performance in relation to the predetermined resource.

Abstract: An improved impulse-operated rotary stepping motor is constructed with a two-part stator assembly and coil support for each stage to reduce manufacturing costs, improve the magnetic characteristics, improve alignment of the rotor of each stage, provide for an integral bearing, make practical the construction of a motor having the rotor teeth on the inside of the rotor armature shell, and to improve and sharpen the detenting action when stopped by bilaterally stepping the top width of the rotor and stator teeth at least once along the length of each tooth.
