Patent CA-1308936-C (CA)
Inventor: AHMED M JAMIL
IPC: G01R23/17
Filed: 1987-10-09
Granted: 1992-10-20
Abstract: OPTICAL FIBRE INTERFEROMETER    Abstract Of The Invention An optical fibre interferometer particularly adapted to provide a light output that is modulated in relation to the intensity of an electromagnetic field includes a single-mode fibre of substantially non-electrooptic material (20, 22 and 24) to which has been spliced (at 26 and 28) a single-mode fibre of substantially electrooptic material (30). When the interferometer is placed in an electromagnetic field, the optical characteristics of the substantially electrooptic fibre are varied, but the optical characteristics of the substantially non-electrooptic fibre are not. As a result, the light passing through the substantially non-electrooptic and electrooptic fibres undergoes a differential phase shift, causing interference upon light recombination that provides the desired light output modulation. Embodiments in which the fibre of substantiallyelectrooptic material is replaced by an optical waveguide of substantially electrooptic material, either formed separately (50, FIGURE 3) or directly (70, FIGURE 4) on the optical fibre itself, are discussed, as is the broad applicability of the interferometer to any situation in which an external parameter is to be measured.

Abstract: A DIFFERENTIAL SWITCHED-CAPACITOR DUAL SLOPE WATTHOUR METER CIRCUIT            Abstract of the Disclosure Transient offset error voltages due to charge injection by MOS analog switches and DC offsets of multipliers in switched-capacitor integrators of electronic metering circuits are compensated by the common mode rejection of a differential switched-capacitor integrator.  To cancel internal DC offset voltages of the integrator amplifier, a series capacitor connected to the inverting input of the amplifier is charged, during the autozero phase of the clock cycle, to a voltage equal to the internal DC offset voltage of the amplifier and subsequently, during the integration phase of the clock cycle, this voltage is applied to the inverting input of the amplifier.

Granted: 1991-02-19
Abstract: ABSTRACT OF THE DISCLOSURE           In a vehicle seat assembly having a backrest member pivotally movable with respect to a seat member, there is disclosed a device for controlled adjustment of the inclination of the backrest member with respect to the seat member, which device includes a redundant locking mechanism which is activated upon failure of the primary locking mechanism so as to prevent uncontrolled rearward pivoting of the backrest member over the seat member.  Moreover, the activation of the secondary locking means is signalled to the seat occupant by a change in the operation of the device, which change in operation prevents the seat occupant from attempting to re-adjust the inclination of the backrest member without servicing of the device by qualified personnel.
