Abstract: Slaves are respectively provided corresponding to electric devices, measure, in real time, power usage states and disposed positions of the electric devices to transmit to a master. The master detects operational states of electric devices on operation based on power usage states received from the slaves, and detects a positional relation between electric devices on operation based on disposed positions of the electric devices. Then, the master estimates the number of residents in the house by determining achievability of operational states of electric devices based on the detected operational states and positional relation of electric devices.

Abstract: If control periods at sensors are equal to each other, a control terminal transmits control commands intended for the sensors at a time to the sensors at the earliest control timing and the latest control timing among control timings at the sensors. If the control periods are different from each other, the control terminal transmits control commands intended for the sensors at a time to the sensors at the start timing and the end timing of the shortest control period. Further, if reception periods in data reception from a sensor is longer than a control period at the sensor, the control terminal transmits a control command to the sensor in response to data reception from the sensor.

Abstract: There is a shredder comprising: a chopped apparatus including an insertion opening for inserting wastes, and an exhaust port for discharging chopped wastes; a waste container which is displaceable between a receivable position where to receive the chopped wastes and a non-receivable position where not to receive the chopped wastes; a claw portion provided with the waste container; a shutter, which opens the exhaust port by moving the waste container to the receivable position, and which closes the exhaust port by moving the waste container to the non-receivable position; a lock member, which is displaceable between a locked position where to close the shutter and an unlocked position where to make the shutter movable; and an operation lever which displaces the lock member to the unlocked position with the claw portion.

Abstract: The invention provides methods for synchronizing a plurality of data flows. In a first method, packets included in a plurality of data flows are sent out in the order of their generation times. A synchronization node adjusts the sending intervals of the packets such that they are the same as the generation intervals of the packets. In a second method, there are different synchronization nodes playing the different roles of sender-side synchronization node and receiver-side synchronization node. A receiver-side synchronization node receives a plurality of data flows from a sending device, and merges those packets in the data flows that have the same generation time into one packet. The merged packets are sent to a sender-side synchronization node, disassembled and restored to the original data flows. The restored data flows are sent by the sender-side synchronization node to their respective destinations.
