Title: Write with light optical notching filter
Inventor: FONNELAND NILS J
IPC: G02B27/46
Filed: 1990-02-08
Abstract: ABSTRACT OF THE DISCLOSURE          An optical notching filter is disclosed in which an optical spatial filter therein is formed by a spatial light modulator which is written into by light.  The optical notching filter system of the present invention provides a linear phase and amplitude response with applications for high speed adaptive filtering to filter out noise and signals of no interest.  In one particular disclosed embodiment, the write with light optical notching filter system of the present invention is designed to adaptively excise interference from Radio Frequency (RF) signals, such as are utilized in communications or radar systems.  The technical approach of the present invention provides a more compact system design than similar electronically addressed optical notching filtering systems, and also significantly reduces the complexity and attendant power requirements of the system.  Different embodiments of a write with light optical notching filter system can operate with either nonochromatic or polychromatic light sources.  Moreover, the write light source can be independent of the read light source, such that any suitable write or read light source can be utilized therein, either with single pass or recursive optical arrangements.

Title: Intravenous system for delivering a beneficial agent
Inventor: THEEUWES FELIX
IPC: A61M5/14
Filed: 1990-02-14
Abstract: ARC l609 CIP 1 ABSTRACT       An agent formulator (30, 60) for an intravenous administration set (14) is provided.  The intravenous administration set (14) includes a container (12) of an IV fluid (13), a drip chamber (22), an agent formulator (30, 60) and an adapter-needle assembly (28). The agent formulator (30, 60) has a fluid inlet (23) and a fluid outlet (25) for maintaining a flow of IV fluid (13) therethrough.  A portion (36) of the formulator wall (32) is comprised of a window material which allows the agent to diffuse therethrough but which prevents convective loss of the IV fluid (13).  A flow distributor (38, 68) is provided within the chamber for distributing the flow of IV fluid (13) along the interior surface of the window (36).  A transdermal-type drug delivery device (40) is adhered to the exterior surface of the window (36).  Drug is delivered by the delivery device (40) through the window (36) and into the flowing IV fluid (13).  The device (40) delivers drug into the IV fluid (13) at a rate that is independent of the flow rate of IV fluid (13) through the  formulator (30, 60).  The rate of drug delivery from the device (40) into the IV fluid (13) is controlled by either the window (36) itself or by a membrane layer (46) in the drug delivery device (40).  A plurality of drug delivery devices (40) may be adhered to the window (36) to deliver a plurality of drugs or to deliver a single drug at a higher dosage rate.  A similar window (11) may be placed in an IV bag to deliver a drug into the IV fluid therein.     Al/PATENTS.LGL/1609CIPl

Title: Digital power metering
IPC: G01R21/133
Filed: 1991-05-24
Abstract: DIGITAL POWER METERING                      ABSTRACT OF THE DISCLOSURE A digital power meter achieves enhanced accuracies through the utilization of a sequence of meter stage improvements. Such improvements include the utilization of a digital phase shift based cycle phase realignment following the scaling function of the meter. The cycle phase corrected signals are digitized utilizing a sampling procedure wherein two samples of both current and voltage are taken within a precisely defined sampling interval. These samples are improved by the application thereto of a truncation correction and are averaged prior to being combined to provide quantity signals such as watt, VAR, volt, amperes, and the like. By developing subinterval transfer of components of these quantities to an overflow register, errors otherwise occurring at this stage of metering are substantially eliminated.

Abstract: In a device for checking a header error in a header part of an STM (synchronous transfer mode) signal (S) which part comprises first through P-th header blocks and an HEC          (header error check) block, each header block comprising first through N-th ATM (asynchronous transfer mode) cell header units, the HEC block comprising first through N-th ATM cell HEC units, a sole error checking section (33, 35, 37) checks the header error in connection with an n-th ATM cell header unit of a p-th header block and an n-th ATM cell HEC unit when a collective control signal indicates the n-th ATM cell header unit of the p-th header block and the n-th ATM cell HEC unit, where n is variable between 1 and N, both inclusive, p being variable between 1 and P, both inclusive. A signal producing section (15) produces the collective control signal for indicating successively the first through the N-th ATM cell header units of the first through the P-th header blocks and subsequently successively the first through the N-th ATM cell HEC units.  On monitoring an ATM cell of a preselected  number of bytes, the ATM cell may be converted into a converted cell of the preselected number of bytes plus an empty byte at first.  Subsequently, an error correcting code is calculated from the preselected number of bytes of the converted cell and is placed in the empty byte to form a full cell.
