  • Patent number: 7980075
    Abstract: A reservoir capable of shortening a time period required to fill a brake system and a clutch system with a fluid with vacuuming in a case where the reservoir has a brake reservoir chamber to be connected to a brake master cylinder of the brake system and a clutch reservoir chamber to be connected to a clutch master cylinder of the clutch system. The reservoir (12) includes a brake reservoir chamber (28) and an inlet port for injecting the brake reservoir chamber (28) with a fluid from outside. The reservoir further includes a clutch reservoir chamber (29) separated from the brake reservoir chamber (28), and a communication passage (37) providing communication between the inlet port and the brake reservoir chamber (28). The communication passage is branched so as to communicate with the clutch reservoir chamber (29).

  • Publication number: 20110021891
    Abstract: In a non-invasive glucose monitor is configured to, by using a heat conductive member having a body surface contacting part for contacting a surface of a human body at its one end, measures a first temperature adjacent to the body surface contacting part and a second temperature adjacent to the other end apart from the body surface. The computing device takes in data of the first and second temperature, environmental temperature, radiation heat from the body surface, reflection light caused by reflecting the light of the two different wavelength at the body surface contacting part. The computing device stores a relationship between parameters and blood glucose levels in advance, thereby converts the above-mentioned data to parameters, and calculates a blood glucose level by applying the parameters to the relationship.

  • Patent number: 7616295
    Abstract: A biometric identification apparatus that can accurately and rapidly perform liveness detection with a simple structure. The apparatus includes a plurality of light sources 102, 103, 106, and 107, each having a wavelength different from one another, for emitting light to a finger 200 as an object to be identified, and receivers 104 and 105 for detecting the light passing through the finger. The ratio of the light emitted from the light sources to the light detected with the receivers is obtained as transmittance. Determination in liveness detection is made by comparing the transmittance with a previously-set threshold of transmittance.
