Abstract: A modulo mi adder and a modulo mi,j scaling unit for use with an RNS. The adder includes a modulo mi barrel shifter, and a dynamic storage unit coupled to the barrel shifter to store the output of the barrel shifter. In a preferred embodiment, the dynamic storage unit includes one dynamic latch for each output line of the barrel shifter, with each of the dynamic latches including a clocked inverter in cascade with an inverter. One modulo mi,j scaling unit includes a modified modulo mi barrel shifter that performs both residue conversion and an arithmetic operation. The residue conversion is performed without using combinational logic. In one preferred embodiment, the modified barrel shifter performs the residue conversion though mi-mj additional columns that replicate normal columns for all modulo mi input lines that are congruent modulo mj.

Abstract: A guide assembly for a rod of a motor vehicle strut comprises a rod guide, a seal cover, and a retainer. The seal cover engages the rod guide, and defames an area therebetween. The retainer is engaged with the seal cover. A first O-ring is disposed between the seal cover and the rod guide, and a second O-ring is disposed between the rod guide and the retainer.

Abstract: Apparatus and methods are provided for use in collecting fluids discharged from a patient and liquids used in various types of medical procedures. The apparatus includes a fluid control pad formed from multiple layers of material and one or more pouches attached to the pad. A first layer of film, or backup sheet, is preferably formed from liquid impervious material such as coextruded low density polyethylene and ethyl vinyl acetate polymers. A portion of the backup sheet is covered with a second layer of superabsorbent material and a top layer of cover stock. The first layer of film may be folded to provided pouches disposed longitudinally on opposite sides of the second layer of superabsorbent material. A strip of fiber reinforced porous web type material may be disposed in the opening to each pouch to assist in directing excess fluids from the second layer of superabsorbent material into the associated pouch.

Abstract: An intrinsic R2R resistance ladder digital to analog converter (DAC) includes a plurality of matched semiconductor ladder switches, one in each of the R and 2R legs of the R2R ladder. The ON resistance of each semiconductor switch being matched to constitute the resistance ladder of the DAC; the ladder switches being operated in response to the digital signal input to the DAC; a reference circuit including a reference semiconductor switch matched with the ladder switches responsive to a reference current to generate a reference voltage; and a voltage follower circuit for monitoring the reference voltage and adjusting the current through the ladder switches to match the voltage at each ladder switch with the reference voltage for precisely fixing the DAC analog output current as a proportion of the reference current in dependence upon the operation of the ladder switches by the digital input signal.

Abstract: A hybrid analog/digital automatic gain control gain recovery system includes a variable gain amplifier (VGA) for receiving a variable amplitude input signal; a first AGC loop includes an analog to digital converter (DAC) for receiving the analog input signal and converting it to a digital signal; a digital gain error detection circuit for detecting variations of the digital signal in a first range and generating a digital error correction signal; and a digital to analog converter (DAC) for converting the digital error correction signal to a first analog correction signal; a second analog AGC loop includes an analog gain error detection circuit, responsive to variations in the output of the VGA in a second range greater than the first range for generating a second analog correction signal; and an integrator circuit responsive to the first and second analog correction signals for providing to the VGA a control signal to adjust the gain of the VGA to accommodate variations in the input signal amplitude.

Abstract: A closure member for a bag has a blade and a sheath. The sheath has side walls that are joined on inner edges and open on outer edges. The blade inserts between the side walls. A partition connects between the side walls near a locking end of the sheath. The partition has a shoulder. A retaining wall locates on the locking end of the sheath, spaced longitudinally from the partition. The blade has a locking member that will insert between the retaining wall and the partition. The locking member of the blade has a shoulder that snaps over the shoulder end of the retaining wall.
