Safe, Convenient Pipetting Device

Safe, convenient, portable pipettor.

A dafe, convenient, portable pipetting device that will accommodate any size pipette is described. A vacuum bulb eliminates the need for external vacuum. Necessary components, fabrication procedures, and operating techniques are given.

Semiautomatic pipetting device (the governor pipet) for clinical chemistry procedures.

USTED et al. reported recently on the use of an electronic fibrin switch for the determination of prothrombin time (1). We have made similar observations and drawn the same conclusions, using this instrument (Fibrometer*). It occurred to us that the semiautomatic pipet employed for the measurement of plasma as well as reagents in the determination of prothrombin time might easily be adapted to ...

Biometric Authentication Platform for a Safe, Secure, and Convenient Society

Yosuke Kaga Yusuke Matsuda Kenta Takahashi, Ph.D. Akio Nagasaka, Ph.D. OVERVIEW: With the rise of issues such as cyber-crime and terrorist threats that have accompanied the growing use of information technology, biometric authentication has attracted attention as a means of identifying individuals to ensure security. However, biometric authentication is mainly used by individuals or individual ...

Device for convenient measurement of spatially varying bidirectional reflectance.

Capturing surface appearance is a challenging task because reflectance varies as a function of viewing and illumination direction. In addition, most real-world surfaces have a textured appearance, so reflectance also varies spatially. We present a texture camera that can conveniently capture spatially varying reflectance on a surface. Unlike other bidirectional imaging devices, the design elimi...
