Title: Multiple discrete autofocus
Inventor: NIHO YOJI G
IPC: G01S13/90
Filed: 1992-11-25
Abstract: MULTIPLE DISCRETE AUTOFOCUS          ABSTRACT A method and autofocus processor that is adapted to automatically correct focus phase errors associated with synthetic array radar signals. The method comprises pro-cessing the synthetic array radar signals to produce a SAR image; identifying and locat-ing potential targets contained in the SAR image; storing the range bin and azimuth location of the target in a target list; bandpass filtering the SAR signals associated with the target scatterer to remove the interference therefrom; forming the pulse pair product of the phase history samples from each reference target to produce a differential phase function; integrating the differential phase function over all reference targets to provide the averaged differential phase history associated therewith; interpolaring the averaged differential phase function to restore the original time scale and number of samples; and computing the focus error from the interpolated differential phase history. The focus error is estimated as a weighted average of the phase history of the detected scatterers. The autofocus processor automatically finds targets and combines data from multiple scatterers effectively and efficiently. The autofocus processor extends the range and resolution limits of SAR systems, and enables the effective use of a SAR sensor with less expensive motion compensation function. The autofocus processor also decouples the SAR sensor (including motion sensors) from its SAR processor, so that the autofo-cus processor produces better images, no matter what sensor is employed.

Filed: 1991-07-17
Abstract: ABSTRACT     The invention relates to a method and an apparatus for separating and removing, from a liquid, bodies (51) of a density which is less than the density of the liquid.  The liquid containing the bodies is supplied to a container whose walls are oriented such that the bodies, on upward flotation to the liquid surface, guide the bodies so that they are concentrated to an area where mechanical devices (26) remove the bodies from the container in association with a first end region (15) thereof.  The liquid is removed from the container via an outlet (31) located on a lower level than the lowest level of the upper defining edge of the end region.  The apparatus for separation and removal of such bodies includes a container (10) whose defining walls form a storage space, which, in the horizontal plane, is of slight cross-sectional area in that region where the mechanical device (26), as a rule, a conveyor screw, is disposed for removing bodies which have floated up to the liquid surface.

Abstract: In a device for confining shopping carts, which is in the form of an accessory unit with control and locking devices (30, 40, 50) for known coin deposit systems (20) for one, an external permanent magnet as a control element (30) is disposed at the end of a shopping cart row which, when passing through the magnetic field (M), interacts with the locking elements (40, 50) of the coin deposit system (20) in such a way that it becomes possible to set up the operational states "Release" (ready to operate) or "Lock" (not ready to operate) exclusively.  Therefore, with the appropriate disposition and size of these components there is operational readiness exclusively in the area of the shopping cart row.  This contact-free interaction is easy to realize structurally and can be securely protected from third party intervention.
Patent CA-2088467-A1 (CA)
Inventor: MORK RAYMOND P
IPC: E02B1/00
Filed: 1993-01-29
Abstract: A method and controls for cyclical operation of ice reducers in open bodies of water.  An ambient condition transducer provides an ambient signal representing the amplitude of a condition affecting ice formation.  A timer cyclically produces a ramp signal, thereby setting the frequency of cycles for operation of a water movement device.  In each cycle a comparator compares the relative amplitudes represented by the ambient and ramp signals and gates power to said device upon a change in the sign of the difference between said amplitudes.  Thus the duration of gated power in each cycle is a function of the ambient condition.

Title: Method and apparatus for detecting credit/debit cards in connection with the processing of bulk mail
Inventor: LILE WILLIAM R
IPC: B07C3/16
Filed: 1993-03-12
Abstract: envelopes with unspecified contents are inspected by a "magnetic imaging" device which operates to identify magnetic indicia associated with the contents of the envelopes in order to identify the orientation of contents within the envelopes and/or to identify magnetic indicia indicative of the magnetic stripe of a credit/debit card or its remnants, an addition to a second detection device (e. g., a thickness measuring device or a metal detecting device) which can then verify whether the indicia indicative of a magnetic stripe signify the presence of a credit/debit card or some other stimulus such as a paper clip or the like. Similar assurances can be provided by employing a thickness measuring device and a metal detecting device, in operative combination (with or without the addition of a magnetic imaging device). Alternatively, the magnetic imaging device may be deleted in favor of a thickness measuring device which, through additional processing, operates to remove subsequent analyses from the time domain in order to achieve a more reliable determination of the contents of an envelope, in less time. Such techniques are applicable to the detection of credit/debit cards contained within 'the envelopes which are to be processed, as well as the detection of other articles which such envelopes might contain, such as folded documents and the like.

Title: Device for shutting off an adaptive algorithm
Inventor: ANDRE TORE M
IPC: H04B3/23
Filed: 1992-02-11
Abstract: ABSTRACT OF THE DISCLOSURE      A device is proposed which is to be used in telephone systems for cancelling echoes which are generated at the transition of four wire lines to two wire lines.  Therefor a signal processor and a microprocessor are provided, where the signal processor is rapid and handles the direct signal processing.  It contains a double talk detector and a calculating device using an adaptive algorithm.  The microprocessor monitors the echo cancelling and sets the stepsize of the adaption.  A direct path is arranged between the detection device and the calculating device in such a way, that when a double talk state is detected, the adaption is immediately and completely shut off inside the calculating device.  The microprocessor, which only periodically monitors the detection device, sets the stepsize of the adaption at a reduced value, when said microprocessor in a periodical check will find, that the double talk state is present.  The adaption having a reduced stepsize is maintained during a long predetermined time period, during which the direct path between the detection device and the calculating device is blocked.
