Abstract:
An imaging includes an image acquisition module which has an image sensor and a first lens system, having a focal plane, for imaging an object onto the image sensor, a display module which displays the image captured by means of the image acquisition module such that a user can perceive it with one eye, and a control unit. A measuring module is provided to the control unit for measuring the accommodation state (B1(t)) of the eye of the user. The control unit adjusts the position of the focal plane of the first lens system on the basis of the measured accommodation state (B1(t)) and, at the same time, adjusts displaying of the image by means of the display module on the basis of the measured accommodation state (B1(t)) such that the user can perceive the displayed image in sharp definition with his eye having the measured accommodation state (B1(t)).
Abstract:
The present invention relates to viral interleukin-6 (v-IL-6), which can be obtained by recombinant expression of the DNA of human herpesvirus type 8 (HHV-8), and which may be used in diagnosis and treatment of human diseases such as kaposi sarcoma, Castleman's disease, multiple myeloma, kidney cell carcinoma, mesangial proliferative glomerulonephritis or B cell lymphoma.
Abstract:
A differential input operational amplifier has a voltage clamp differential transistor pair coupled to an input differential transistor pair of the operational amplifier. The voltage clamp differential transistor pair limits the output voltage of the operational amplifier by taking over control of the operational amplifier circuits from the input differential transistor pair as the output voltage approaches a clamp voltage value. A reference voltage may be used to set the output voltage at which the input differential transistor pair will be clamped by the voltage clamp differential transistor pair. Below the clamp voltage, operation of the input differential transistor pair will not be affected. At the clamp voltage the input differential transistor pair will no longer control the output of the differential amplifier, rather the voltage clamp differential transistor pair will control the maximum voltage output of the differential amplifier. Both positive and negative limiting of the operational amplifier output voltage may be accomplished.

Abstract:
The present invention relates to a method for determining an analyte in a sample. According to the method of the present invention, a probe is transferred from a stamp member onto an analyte that is bound to a support member. The present invention is particularly suitable for microarrays.
Abstract:
The regulated output voltage of a voltage regulator is maintained up to a current limit, Ilimit, then as the load impedance continues to decrease the output current does not increase past the current limit, Ilimit, but rather the output voltage decreases forcing the output current to also decrease to satisfy Ohm's Law: IOUT=VOUT/ZLoad. When the output voltage drops below the regulated voltage value because of current limiting the voltage regulator shifts from a current limit mode to a current foldback mode wherein the output current decreases with the decrease in output voltage until the output current reaches a current foldback minimum, Ifoldback, at an output voltage of substantially zero volts. As the load impedance increases so will the output voltage and current until the output voltage is back at substantially the regulation voltage value, and the output current is less than or equal to the current limit, Ilimit.

Abstract:
A rotary container handling machine which has a stationary frame and a turntable supported thereby, which turntable has container handling devices for handling containers. The turntable is rotated by a drive. The drive comprises an encircling collar with a plurality of magnets, and at least one stator which overlaps one subsector of the collar to permit rotation of the turntable by an electromagnetic field generated by the at least one stator. The collar is disposed on either the stationary frame or the turntable, while the at least one stator is disposed on the other.
