Abstract: A digital-to-analog converter comprises a digital-to-ana­
log converting section for converting digital input data into an 
analog output signal and an error correction circuit. The error 
correction circuit selectively generates one of different amount 
of analog signals in response to a specific state of a predeter­
mined bit of the binary input data, the amount of the generated 
analog signal being a 2 -N  (N is an integer) magnification of that 
amount of the analog output signal which corresponds to the 
least significant bit of the binary input data. The thus generated 
analog signal is fed to the digital-to-analog converting section 
to shift the analog output signal by the amount of the gene­
rated analog signal.

Title: Adaptive equalizer
IPC: H04L25/03
Filed: 1986-02-12
Abstract: High-speed bipolar signals transmitted along standard twisted pair (17) telephone wiring are subject to InterSymbol Interference which is corrected by an equalizer circuit (10) that is operably responsive to predetermined parameters of bipolar signals detected at the secondary (21) of a line transformer (15). These parameters are input to a control logic circuit (11) which includes several stages, each producing a set of past dependent logical control signals which are input to corresponding equalizer tap circuits (25) (26) (27) having outputs connected to a common output bus (40). Each tap circuit (25) (26) (27) includes an integrator (46) that is incrementally charged and discharged by an electronically switched capacitor (51). A tap weight voltage output from each integrator (46) is subsequently summed directly or inversely by a second switched capacitor (52) under control of the logical input signals. And, an equalizing signal output from the second capacitor (52) is coupled through a buffer amplifier (41) to the line transformer (15) where it is added to the incoming signal and allows eye diagram monitoring directly at the transformer (15).

holder includes a cylindrically-shaped plug member (10) that 
has a recessed shoulder (21) at one end sized to frictionally 
engage the inside surface of the body of the heart valve 
prosthesis (12). The other end of the cylindrical plus is in the 
form of a V-shaped seat (30). Two passages (25) extend 
through the plug member and a wall (27) projects upwardly 
from the peruphery of the seat adjacent each of the 
passages. A separate grip member (11) includes two legs 
924), each sized in length to extend through the passage­
ways (25) in the plug member. The two legs each include a 
base member (25) to which each leg is respectively con­
nected at an angle inward from the outer edge of the base 
member. The two base members are hinged (31) together 
with the legs biased outwardly, and each leg has an 
outwardly projecting foot (28) at the distal end thereof. To 
secure a heart valve prosthesis (12) fitted on the recessed 
shoulder (21) of the plug member, the legs (24) of the grip 
member are inserted into the passageways (25) of the plug 
member. When the upper ends of the legs engage the walls 
of the upper ends of the passages, the legs are cammed 
outwardly so that the legs are substantially parallel with the 
axis of the plug member and the feet (28) on each leg engage 
the edge of the valve body of the prosthesis to prevent its 
removal from the plug member. Once the prosthesis is 
sutured in place, the grip member is released by lifting a tab 
(45) that extends upwardly from one of the base members.

IPC: C12N11/12
Filed: 1987-01-30
Abstract: The subject invention concerns an improved method of 
enzyme immobilization using polysulfonium salts. Some of 
the polysulfonium salts, advantageously, can be used to both 
flocculate and crosslink microbiologically-produced enzyme 
or cellular materials containing the enzymes. In such in­
stances, the immobilization process is highly cost-efficient. 
The replacement of the prior art crosslinker of choice, glut­
araldehyde, with a polysulfonium salt results in greater reten­
tion of enzyme activity during the immobilization process.

IPC: A61M1/34
Filed: 1987-01-20
Abstract: The apparatus comprises means for circulating 
and for treating blood, with a control means for 
controlling the circulating means. A first pump 
(104) controls the flow rate of blood entering a 
filter (142) while a second pump (106) controls the 
flow rate of the blood exiting the filter (142). The 
filter (142) includes a sealed, ported chamber 
surrounding a microporous membrane, the rate of 
filtration of components removed from the blood 
passing through the membrane being directly 
proportional to the transmembrane pressure.  
     Display and input devices (240, 250) transmit 
information between a central processor (210) and an 
operator who operates the apparatus. Sensors (220, 
236) measure pressures at the inlet and outlet of the 
filter (142). Blood flow rate is calculated from the 
speeds of the pumps (104, 106).  
     The central processor (210) receives input data 
from the sensors (220, 236) and the pumps (104, 106) 
to regulate the apparatus, and in particular regulate 
the second pump to maintain a specified outflow rate, 
and maintain a desired average transmembrane pressure 
while the second pump rate remains constant. The 
central processor (210) regulates the first pump 
speed as necessary to achieve the desired 
transmembrane pressure, while the second pump rate is 
held steady.
