Title: Apparatus and method for capacitance measurements
IPC: G01R27/26
Filed: 1989-05-08
Abstract: A circuit and method for measuring the capacitance of 
a medium independent of the resistivity of the medium. A 
triangular voltage Vt is applied to plates (22) immersed in 
the medium to generate both a resistive current component 
(i(R) in phase with the triangular voltage and a 
capacitive current component i(C) in phase with a 
differential of the triangular voltage. The resistive and 
capacitive current components are summed (32) with a 
selectable current i(ST) which is provided having a phase 
π radians out of phase with the triangular voltage and 
having an amplitude related to a control signal. The 
summed current is sampled (42) over a time period phase 
shifted from the capacitive current component and then 
integrated (46) so that the capacitive current component 
integrates to zero and the integral of the resistive 
current component minus the selectable current provides the 
control signal. In response to the control signal, the 
selectable current is varied until the sum of the 
selectable current and resistive current component are 
nulled. This summed current is then sampled (44) in phase 
with the capacitive current component thereby obtaining a 
measurement of capacitance independent of resistance.

Patent EP-0688532-A3 (EP)
Inventor: HORIE MASAO
IPC: A61B5/151
Filed: 1995-06-01
Abstract: A suction-type blood sampler has a housing (1), a lancet unit
(2) having a rod (4) extending backward from the lancet unit, and
a plunger (3) connected to the rod in the housing and having a seal
(7) attached to a forward end of the plunger. The seal is in
sliding airtight contact with an inner periphery of the housing.
The lancet unit consists of a lancet body (11) having a forwardly
extending needle (12) and held by a lancet retainer (18) which is
in sliding contact with the inner periphery. The blood sampler
further has first, second and third springs (8, 9, 10) placed
between the lancet unit and the plunger. The second spring urges
the lancet unit to project the needle forwards, and the third
spring tends to retract it. The first spring acts to reduce air
pressure in the housing when the plunger is released. The blood
sampler also has a checking means (32) disposed in the plunger so
as to exhaust air and inhibit ambient air from entering the
housing, so that the skin is pierced sharply and quickly, and by
introducing ambient air into the evacuated housing, just a required
amount of blood can be taken accurately and without any fear that
the blood will scatter when the open end of the housing is removed
from the skin.
