Abstract: A stable reference solution for calibrating and monitoring blood gas instrumentation is disclosed. The solution comprises an aqueous mixture containing a hemoglobin solution derived from a mammalian.source.which comprises at least about 95 % re-duced hemoglobin. The solution additionally contains a bicarbonate buffer and a metal catalyzed methemoglobin reducing sys-tem and an organic buffer. To provide a control element having a variety of properties similar to fresh, whole, human blood, the reference solution is stored in a sealed ampule under an inert atmosphere containing CO2 until just prior to use. The ampule is subsequently opened and the solution is equilibrated with a gas mixture having components which provide gasses in a phy-siological range to the solution. The solution is characterized by exhibiting properties similar to fresh blood subsequent to equilibration and an extended storage life prior to equilibration.

Inventor: TSUKADA SATOSHI
IPC: G10L15/32
Filed: 1992-02-06
Granted: 1996-10-29
Abstract: In a speech recognition device including a similarity calculator (16) for calculating a usual similarity as a provisional similarity between an input pattern and prepared reference patterns, a calculating arrangement (17, 18) calculates a reference similarity between the input pattern and produced  reference  patterns.  A correcting unit (21) corrects the provisional similarity by the reference similarity into a corrected similarity.  As usual, the similarity may be a dissimilarity.  The prepared reference patterns may be memorized in the calcultor or be given by concatena-tions of primary recognition units.  Preferably, the produced reference patterns are concatenations of secondary recognition units memorized in a memory (18).

Title: Electric current measurement apparatus for a solid state motor controller
Inventor: UNSWORTH PETER J
IPC: G01R19/165
Filed: 1992-05-07
Granted: 1997-12-16
Abstract: An electric induction motor is coupled to a source of alternating current by a thyristor switch.  A control circuit triggers the thyristor switch to create conductive and non-conductive states during each cycle of the alternating current.  A circuit senses the voltage across the thyristor switch during a non-conductive state.  From that sensed voltage and known characteristics of the motor being controlled, the control circuit derives a measurement of the current flowing through the motor in the conductive state of the thyristor switch.  One of two different derivation techniques is used depending upon the length of the non-conductive state.  The control circuit includes a means for calibrating the derivation of the current measurement for a specific motor.

Title: Method and apparatus for measuring irregularities and hardness of a roll surface
Inventor: JUSTUS EDGAR J
IPC: G01L5/00
Filed: 1991-02-22
Granted: 1996-04-02
Abstract: A pressure sensitive device, such as a piezoelectric strip (16) or plurality of piezoelectric crystals (32), is or are arrayed along the surface of a roll, preferably in a spiral pattern, extending for one revolution of the roll (12) which is nipped with an-other roll (14). The nip pressure between the rolls, with or without a paper web passing through the nip, produces a signal by the piezoeletric device (16) indicative of irregularities along the nip (N). These irregularities, which can be indicative of variations in the web caliper, roll surface, hardness and other parameters of roll or web quality, are then passed to a monitor (38) for continu-ous read-out of the irregularities or non-uniformities along the face of the roll. Other apparatus, such as signal conditioning means (30) and encoder means (22), can be provided for processing the signals determining the exact axial location along the roll surface of the pressure sensitive device passing through the nip (N) at any given time.

Title: Arrangement for demodulating speech signals discontinuously transmitted from a mobile unit
Inventor: HAYATA TOSHIHIRO
IPC: G10L19/06
Filed: 1993-10-12
Granted: 1997-12-16
Abstract: The disclosure is to eliminate discomforting background noise regenerated at a receive side (viz.,a base station) in a mobile radio communications system wherein discontinuous transmission (DTX) is utilized. When speech pause is detected at the receive side, synthesis filter coefficients are produced using a background noise code which has been transmitted from a mobile unit. Subsequently, a Q value of the synthesis filter is measured using the above-mentioned synthesis filter coefficients. If the Q value is larger than a threshold level, each of the filter coefficients is lowered by a predetermined value. Thus, the regenerated discomforting background noise can effectively be reduced.
