Title: Acoustic echo canceler
Inventor: SHAW DAVID GOODWIN
IPC: G10L21/0208
Filed: 1996-04-15
Abstract: Acoustic echos are canceled by employing a first echo canceler having a comparatively long first impulse response synthesis capability which is connected between a transmit path and receive path for generating  a first error signal and for canceling echo signals in the transmit path, and at least a second echo canceler having a comparatively short second impulse response synthesis capability connected in parallel with the first echo canceler between the transmit and the receive path.  The second echo canceler is supplied with the first error signal from the first echo canceler and is adaptively operating simultaneously with but independent of the first echo canceler to further cancel echos in the transmit path.  Specifically, the first echo canceler is intended to capture the substantially stationary and any  slowly  varying  components of the echo path impulse response, and the second echo canceler is intended to capture the more time varying, i.e., dynamically varying, component of the echo path impulse response.  I have recognized that in certain applications, the more time varying component of the echo path impulse response may exist in a relatively short time interval. For  instance, in the canceling of acoustic echos, the most time variation in the echo path impulse response results from the movement of objects and/or persons near either the microphone or the loudspeaker.   This movement results in significant changes in the early portion of the echo path impulse response.  Aligning the tap coefficients of the second echo canceler with this early portion of the echo path impulse response provides significantly enhanced echo cancelation  performance  over that achievable with only the first echo canceler. This is realized by placing a "short" fixed delay in series with the receive path signal to the second echo canceler. In other applications, the time varying component of the echo path impulse response still exists in a relatively short time interval, but the time varying component  relative to the overall echo path impulse response may change with time or may not be known a priori. Under these circumstances,  it is desirable to dynamically align the coefficients of the second echo canceler over the echo path impulse response. This is realized by employing a dynamically adjustable delay in series with the receive path to the second echo canceler. In one embodiment, the delay value is dynamically generated in response to the tap coefficient values of the first echo canceler.

Abstract: A private base station supports the registering or multiple mobile stations and provides a personalized call delivery feature for each registered mobile station. Each mobile station registers separately with the base station when within communication range of the base station. When registration of a mobile station with a private base station is performed, the private base station communicates mobile station information to a base station location register along with assignment of a local unique address for each one of the multiple mobile stations registering with the private base station. When the private base station receives an incoming call for a particular one of the mobile stations, this local unique address associated with the particular station is provided by the base station location register as part of the incoming call information also received by the base station thereby allowing the base station to distinctively alert the particular mobile station. By obtaining a local unique address for each of the mobile stations, the private base station is also able to advantageously offer various intelligent features which are personalized according to customer needs. For example, a calling party may have his or her name displayed on the reached mobile station for the convenience of the user at this mobile station.

Title: Method and system for allocating and redeeming incentive credits between a portable device and a base device
Inventor: SVIGALS JEROME
IPC: G06Q20/38
Filed: 1995-02-02
Abstract: A customer incentive system involving a plurality of service or merchandise providers comprises a customer-carried, portable device (74), a provider device (76), and a base device (72).  To earn incentive credits, the customer enters into a transaction with one of the providers participating in the incentive system (70).  A transaction amount is derived from the transaction and, based on this  amount, an incentive credit amount is computed.  The base device (72) performs this computation by deriving an incentive code and cross-referencing  this incentive code with all customer incentive codes stored on the customer-carried device (74) and  incentive program codes stored on the provider device (76) to derive an incentive rate. This incentive rate is applied to the transaction amount to derive the incentive amount. The incentive amount is stored on the customer-carried device (74). To redeem the incentive credits stored on the customer-carried device (74), the customer enters into a second transaction with the same provider or another participating provider.  A second transaction amount is derived from this transaction and the customer may choose to redeem some or all of the incentive credits stored on the customer-carried device (74) to lower the transaction amount. When incentive credits are redeemed, they are subtracted from the incentive amount on the customer-carried device (74).  By using a customer-carried device (74), transactions may be conducted off-line.  Thus, no concurrent communications linkwith a central authority is needed.

Abstract: The invention concerns an interference-control circuit for switching power supplies suitable for use in the operation of both discharge and incandescent lamps. The interference-control circuit has at least one controlled auxiliary supply (ZW, F) plus a control circuit (TR1). The auxiliairy supply/supplies (ZW, F) generate controlled compensation signals which are inverted with respect to the interference signals caused by the fast switching transistors (T1, T2). The auxiliairy supply (ZW, F) is connected either parallel to the source of interference and capacitively to the environment or in series with the source of interference and galvanically into the supply leads. In the first case, the auxiliairy supply preferably includes, near the switch (T1, T2), a metal surface (F) whose potential variations are inverted with respect to those of the source of interference essentially round the junction point (M) between the switching transistors (T1, T2) e g. by means of the transformer (TR1). In the second case, the auxiliairy supplies are preferably formed by two secondary coils of a transformer. The primary coil is controlled by the potential changes in the source of interference and induces in the leads of the secondary coil an opposite phase common-mode compensation signal. Optionally, the interference-suppression circuit can be designed as a closed control circuit, the common-mode interference current in the leads being used as the regulating variable.
