Title: Device and program for power monitoring control
Inventor: WATANABE TAKAYUKI
IPC: H01M8/00
Filed: 2020-03-30
Abstract: To increase the success rate of power information acquisition in comparison with a case of power information acquisition from a smart meter at a constant interval, by executing radio communication with HEMS at an interval by which use power transition of a house can be recognized within a constant error range and determining whether or not the communication is successful based on a communication history or a power information history of the house to adjust the interval accordingly.SOLUTION: A communication interval adjustment unit 52 elongates a communication interval when a communication success rate falls below a threshold. For example, if the communication interval is elongated from once every 30 seconds to once every 40 seconds, a possibility of the occurrence of communication interference of other apparatuses in the self-house or neighboring houses, or communication standby to avoid interference decreases, so that the communication success rate increases. The increased communication success rate can produce an optimal power generation output by a cogeneration device 10. This enables achieving reduced primary energy consumption, reduced carbon dioxide emission and reduced energy cost.SELECTED DRAWING: Figure 4

Title: Failure prediction device
Inventor: NAKANO MOTONARI
IPC: D05B51/00
Filed: 2020-03-31
Abstract: To provide a failure prediction device which can prevent occurrence of sewing failure.SOLUTION: A sewing machine acquires a feature amount from a variation tension and a variation movement amount that periodically vary during sewing (S21). The feature amount is the amount showing the feature of occurrence of sewing failure that varies before occurrence of sewing failure. A needle thread tension and a needle thread movement amount during a balance raising period and a shuttle capture period are examples of the feature amount. The sewing machine predicts occurrence of sewing failure based on the shift of the feature amount by a prediction unit (for example, a sewing period for one needle stitch) (S35-S37). For example, when the needle thread tension in each of the balance raising period and the shuttle capture period shows the tendency to increase, or when the needle thread movement amount in each of the balance raising period and the shuttle capture period shows the tendency to decrease, the sewing machine predicts the occurrence of thread breakage.SELECTED DRAWING: Figure 13
