Abstract: A novel method for bonding of micro elements with in-situ bonding means is disclosed. Suited bonding means include heating coils and bonding materials. The bonding means are provided in the elements to be bonded during their preparation. While the elements are bonded, electric power is applied to the heating coil such that the bonding material is melt and that the elements are bonded. An elastic calibration means is provided in at least one of the elements to be bonded such that the distance and parallelism of the elements may be calibrated during the bonding process.

Abstract: A non-invasive blood glucose meter includes a near-infrared energy analyzer which includes a light filter assembly of two Fabry-Perot interferometers and a photosensor. The near-infrared energy analyzer detects near-infrared energy absorbed by a human or animal body and generates spectra of such absorption so that the blood glucose content in the body may be analyzed. In order to provide stable energy absorption information of the blood, special designs are provided to stabilize the light source, to calibrate the spectrum and to obviate the noise from the heartbeats of the body. A single crystal silicon elastic power source is used to provide the driving power of the Fabry-Perot interferometer to avoid mechanical hysteresis.
