US11336534B2	Network operation A method of operating a communications network is disclosed. In order to manage a network, it is first necessary to establish the state the network is in. This is difficult in practice because the network operational data stored and transmitted in the network takes a myriad of forms owing to the variety of suppliers and types of network equipment.

This in turn leads to the network management apparatus controlling the network to operate in a more efficient manner than has hitherto been possible.

US11336272B2	Low power single retention pin flip-flop with balloon latch Systems, apparatuses, and methods for implementing a low-power, single-pin retention flip-flop with a balloon latch are described. A flip-flop is connected to a retention latch to store a value of the flip-flop during a reduced power state. A single retention pin is used to turn on the retention latch. During normal mode, the retention latch is pre-charged and a change in the value stored by the flip-flop does not cause the retention latch to toggle. This helps to reduce the power consumed by the circuit during normal mode (i.e., non-retention mode). When the retention signal becomes active, the retention latch gets triggered and the value stored by the flip-flop is written into the retention latch. Later, if the flip-flop is powered down and then powered back up while the circuit is in retention mode, the value in the retention latch gets written back into the flip-flop.

US11335574B2	Light-irradiation type thermal processing method and thermal processing apparatus From a stage of preheating by a halogen lamp to irradiation with a flash by a flash lamp, a radiation thermometer is used for measuring the temperature of a back surface of a semiconductor wafer. A increased temperature ΔT is determined by which the back surface of the semiconductor wafer is increased in temperature from the preheating temperature by irradiation with a flash. The specific heat of the semiconductor wafer has a known value. Further, the increased temperature ΔT is proportionate to the magnitude of energy applied to a front surface of the semiconductor wafer by irradiation with a flash. Thus, a front surface attained temperature of the semiconductor wafer can be determined using the increased temperature ΔT of the back surface of the semiconductor wafer during irradiation with a flash.
