Title: Method of monitoring a dialysis unit
Inventor: PIRAZZOLI PAOLO
IPC: A61M1/14
Filed: 1992-07-08
Abstract: A method of monitoring a dialysis unit is provided herein. The method includes the first step of acquiring and storing set values for a plurality of parameters relating to the treatment to be carried out. The parameters include the infusion rate of a solution containing bicarbonate (HCO3-). The method then includes the step of calculating a clinical prescription of the concentration, in blood, of bicarbonate ([HCO3-]b), which will result from a treatment based on the stored values of the parameters. The clinical prescription is calculated using a mathematical model of the relationship between the treatment parameters and the clinical prescription ([HCO3-]b). The method then includes the step of comparing, during the treatment, set values of the parameters with initially stored set values of the parameters. The method then includes the step of determining suggested values for one of the parameters so as to maintain the clinical prescription ([HCO3-]b) unchanged.  If any variation is detected between the set values of the parameters and the initially stored set value of the parameter, the method then includes the step of determining any change in the clinical prescription ([HCO3-]b) resulting from the change in the set values of the parameter. The method then includes the step of generating an alarm signal when a variation in the clinical prescription ([HCO3-]b) is detected.  The method then includes the final step of displaying the suggested value.

Filed: 1993-02-23
Abstract: A digitizer tablet computer has a host processor connected to a service processor which,  in turn,  is connected to a digitizer   controller   and   to   a   power   subsystem microcontroller whereby primary control of a keyboard,  a digitizer, and a power subsystem is off loaded from the host processor  to  the  service  processor.  The  host  processor communicates with the service processor through an interface comprising a status register, an input buffer and an output buffer through which host commands and data are transferred. The digitizer produces coordinate data that is initially processed in the service processor before being passed on to the host processor.  The host processor is interrupted to receive the processed data and executes in a tight loop until a predetermined amount of processed data is received.

Title: Mixer circuit
Inventor: SHIGA NOBUO
IPC: H03D7/12
Filed: 1993-03-05
Abstract: ABSTRACT OF THE DISCLOSURE   An FET mixer circuit having a stable input impedance uses two tandem-connected GaAs MESFET's (1) and (2) of pulse doped structure instead of a conventional MESFET or a HEMT, as an active device. A gate biasing point for the FET (1) is set around a pinch-off point of a mutual conductance, and a gate biasing point for the FET (2) is set in a region which assures non-change of a mutual conductance with respect to the increase of a gate voltage.  Thus, a mixer circuit having a good isolation characteristic for an RF signal and a local oscillation signal and exhibits substantially no change in the input impedance is attained.

Abstract: ABSTRACT          A process for treating a fibrous and/or porous material is disclosed.  The process comprises treating the material with a curable polymer solution, usually an aqueous solution, curing the polymer and drying the material.  The dried material is then irradiated with microwaves and the heat emission due to residual humidity is detected, for example with the aid of a temperature measuring device.  The heat-emitting part of material is separa-ted, usually by a sorting device controlled by the temperature measuring device, and subjected to additional drying.  The process is applicable to a wide range of materials, such as rock wool, glass wool, ceramic fibres, textile-type materials and mixtures thereof.  It is particularly useful for manufacturing materials which should be free of residual humidity, such as materials used in the building industry.
