    摘要： Disclosed are embodiments of a system and of an associated method for estimating the leakage current of an electronic circuit. The embodiments analyze a layout of an electronic circuit in order to identify all driven and non-driven nets within the electronic circuit, to identify all of the driven net-bounded partitions within the electronic circuit (based on the driven and non-driven nets), and to identify, for each driven net-bounded partition, all possible states of the electronic circuit that can leak. Then, using this information, the embodiments estimate the leakage current of the electronic circuit. This is accomplished by first determining, for each state of each driven net-bounded partition, a leakage current of the driven net-bounded partition and a probability that the state will occur in the driven net-bounded partition during operation of the electronic circuit. Then, for each state of each driven net-bounded partition, the leakage current of the driven net-bounded partition and the state probability are multiplied together. The results are then aggregated.

    摘要： A method of estimating a leakage for a plurality of transistors in an integrated circuit that accounts for narrow channel effects includes determining an expected total leaking transistor width for the collection; determining an expected total number of leaking transistors for the collection; determining an average width of a leaking transistor from the expected total leaking transistor width and expected total number of leaking transistors; estimating a leakage for a transistor of the average width; and determining the estimated leakage for the collection of transistors by multiplying the leakage for a transistor of the average width by the expected total number of leaking transistors for the collection.

    摘要： A heat exchanger has heat exchange elements and an inlet header and an outlet header that fluidly communicate with the heat exchange elements. The inlet header has a fluid inlet. The heat exchange elements are connected to the inlet header along a length of the inlet header and are various distances from the fluid inlet. A distributor is located inside the inlet header, which distributor forms a perforated wall between the fluid inlet and the heat exchange elements. The distributor provides back pressure to incoming fluid into the inlet header, wherein the fluid is evenly distributed between the heat exchange elements.

    摘要： An evaporator condenser has a condenser unit which has plural plate units separated from one another by air gaps. Each plate unit has first and second plates that are coupled together about a perimeter thereof. Each plate unit has a first edge and an opposite second edge. The first and second plates are coupled together along at least one line so as to form a first channel that extends from the first edge to the second edge in the second channel by communicates with the first channel and extends back to the first edge. The channels decrease in volume from an inlet to an outlet.
