Filed: 1988-04-26
Granted: 1991-05-07
Abstract: The antenna includes at least one group of antenna elements (EA1, EA2, . . . , EAp). Microwaves emitted by a central emitter (EH) reach a particular element (EA1 for example) by passing through a controllable phase shifter (VE1), a laser (LE1) which modulates a carrier light signal at a frequency specific to said antenna element with the microwaves, via an optical deflector (FIE) which injects said light signal into an optical waveguide (GE) which is common to all of the antenna elements in the group, via an optical deflector (FPE) which directs said light signal to a detector which is specific to said antenna element (EA1), and which reconstitutes the microwaves, and via a microwave amplifier (AE1) which applies the microwaves to said antenna element. The system is applicable to telecommunications and to radar.

IPC: H02H3/05
Filed: 1989-05-31
Granted: 1993-01-12
Abstract: W.E. 54,363 Abstract of the Disclosure The offset in digital samples of the voltages and currents in a power transmission system following a fault is reduced  by  subtracting  a  linear  approximation  of  the exponential component of the transient from the magnitude of the samples to extract the sinusoidal component.  The slope and initial ordinate value of the linear approximation are derived  from  simple  calculations  using  pairs  of  digital samples spaced one-half cycle apart.  Compensated values of the  digital  samples  for  the  first  half  cycle  of  the transient  are  produced  within  one-half  cycle  plus  one additional sampling interval from fault inception.

Abstract: A prefilled syringe for one or two component medicaments is based upon the use of a vial containing a medicament or one component of a medicament, the vial having an open bottom closed by a piston. When the piston is coupled with a plunger, and an adapter cap having an internal needle and an external connection for a needle is placed over a cap of the vial, the latter is converted into a prefilled syringe. The piston has an axial passage closed by a resealable septum, so that a separate diluent stored in a flexible capsule may be introduced into the vial through the piston by a double ended needle mounted on a further cap applied to the capsule, the further cap being coupled within the tubular interior of the plunger so that the double ended needle penetrates the septum in the piston. The capsule is pushed forward onto the double ended needle when its contents are to be expelled into the vial. The capsule and its cap are then removed and discarded.
