摘要： Invention relates to a vibration detection instrument assembly (20) comprising a vibration detection instrument (22) having a body part (24), which is provided with a support surface (26) and an attachment screw (28) extending from the support surface (26) in the direction of its normal, by means of which the vibration detection instrument (22) is assemblage to a device intended to be monitored, which vibration detection instrument (22) comprises a vibration sensor (30, 30.1,30.2,30.3) configured to detect vibration at least in a direction deviating from longitudinal axis of the attachment screw (28). The vibration detection instrument assembly (20) comprises a deformable base part (36) arranged at least partly against the support surface (26) of the body part (24). Invention relates also to method of assembling a vibration detection instrument assembly (20) to a device (10) to be detected.

摘要： An input device that inputs information corresponding to a change in pressure due to load has: a first charge detection circuit 11 that outputs a first detection signal Sp corresponding to charges generated in a first piezoelectric sensor P1 and a second piezoelectric sensor P2; and a switch circuit 20 that is provided on a path through which the charges are transmitted from the first piezoelectric sensor P1 and the second piezoelectric sensor P2 to the first charge detection circuit 11. The first charge detection circuit 11 alternately iterates a first period T1 in which a first charge Q1 is input from a first positive electrode EP1 via the switch circuit 20 and a second period T2 in which a second charge Q2 is input from a second negative electrode EN1 via the switch circuit 20, reverses a sign of one of the first charge Q1 and the second charge Q2, combines a resulting charge with the other charge, and outputs the first detection signal Sp corresponding to the amount of accumulation of the combined charge.
