Abstract: A personal assistant control system which enables a robotic personal assistant to properly support a user according to the user's growth, includes: a first personal assistant (PA) 1 used in a first period to acquire information from a first sensor group; a second PA 2 used in a second period to acquire information from a second sensor group; and a server 5 connected to the first PA 1 and the second PA 2 via a network and configured to estimate a state of a user 3 based on information acquired from the first or second sensor group. In a third period T3 bridging the first period T1 and the second period T2, the server estimates the state of the user 3 based on information acquired from common sensors which are specific types of sensors included in the first and second sensor groups and configured to acquire common attributes.

Abstract: A compact, high-performance thermoelectric conversion module includes a laminate having a plurality of insulating layers, p-type thermoelectric semiconductors and n-type thermoelectric semiconductors formed by a technique for manufacturing a multilayer circuit board, particularly a technique for forming a via-conductor. Pairs of the p-type thermoelectric semiconductors and the n-type thermoelectric semiconductors are electrically connected to each other in series through p-n connection conductors to define thermoelectric conversion element pairs. The thermoelectric conversion element pairs are connected in series through, for example, series wiring conductors. The thermoelectric semiconductors each have a plurality of portions in which the peak temperatures of thermoelectric figures of merit are different from each other. These portions are distributed in the stacking direction of the laminate.
