Abstract: Abstract of the Disclosure:           In an echo cancelling device comprising an echo canceller 13 for producing, in response to a send-in signal SIN and a receive-in signal RIN, a residual signal RES in which an echo signal ECHO is cancelled, a residual echo level estimator 106 estimates, in response to the residual signal, a residual echo level in the residual signal and produces a threshold signal THR with a threshold level equal to the residual echo level. Responsive to the receive-in, the residual, and the threshold signals, a residual echo suppressor 105 produces a send-out signal SOUT with a residual echo adaptively suppressed in response to the threshold level. Preferably, the echo canceller comprises an echo estimating circuit 131 which estimates an echo estimation signal in response to the receive-in and the residual signals.  A subtracter 132 subtracts the echo estimation signal from the send-in signal and produces the residual signal.  Responsive to the send-in and the receive-in signals, a communication state detector 14 produces an inhibit signal INH when a level of the receive-in signal is greater than that of the send-in signal.  The inhibit signal prevents the echo estimating circuit from producing the echo estimation signal and makes the residual echo level estimator keep the threshold level at the residual echo level estimated immediately before the inhibit signal is produced.

Title: Bispecific antibody heterodimers
Inventor: TSO J YUN
IPC: A61K38/00
Filed: 1992-11-25
Abstract: Methods for producing and using bispecific antibodies formed by leucine zippers are provided. Leucine zippers capable of preferentially forming heterodimers are respectively linked to epitope binding components comprising different binding specificities.  Bispecific antibodies are formed by pairwise association of the leucine zippers, forming a heterodimer which links the two distinct epitope binding components. Heterodimerization can occur by interaction of the two leucine zipper regions, forming a bispecific antibody. Such a bispecific antibody may be further stabilized by the formation of intermolecular chemical bonds, such as disulfide bonds, between the two monomeric subunits. Subsequent to the formation of such intermolecular bonds between the monomeric subunits, the leucine zippers may be removed or retained. Bispecific antibodies produced by these methods are substantially pure and may be produced in high yields and on a large scale. Alternatively, bifunctional heterodimers may be formed by linking an epitope binding component to a macromolecular species that is not an epitope binding component.

Abstract: A method for recovering from a reset in a microprocessor includes steps of evaluating a predetermined pattern in a volatile memory (102), determining the type of reset which occurred depending upon whether the predetermined pattern is intact (103); and initializing the memory depending upon the type of reset. In particular, all locations in the memory will be initialized if a "power on" reset occurs (107) and initializing only selected portions of the memory if a "static" or "cradled" reset has occurred (104). If a static or cradled reset has occurred, all locations of the memory are initialized except those locations including state information to allow normal operation of the microprocessor. That is, the operation of the microprocessor based device can be restored without interruption after the reset.
