Title: Receiver with analog and digital channel selectivity
Inventor: VOBORIL CHARLES J
IPC: H03J3/08
Filed: 1998-01-26
Granted: 2001-04-17
Abstract: A radio receiver for receiving radio frequency (RF) signals includes an analog down-converting and filtering section for down-converting and selecting the RF signals to an intermediate passband and a stopband which substantially determine the widest bandwidth of operation of the radio receiver. An analog-to-digital converter converts the intermediate frequency signal to a sampled digital signal. A digital filtering section, responsive to the sampled digital signal, includes wideband and narrowband digital filters for providing wide bandwidth and narrow bandwidth baseband quadrature output signals for the widest bandwidth of operation and a narrow bandwidth of operation at a frequency within a passband. The wideband digital filtering is designed to only provide a modest amount of additional stopband attenuation with a significantly sharper transition band rolloff from passband to stopband. When this limited digital filtering is applied to the signal that has already been subjected to the analog filtering, the selectivity of the overall receiver frequency response is improved. The receiver may be used for multi-bandwidth operation by simply adding digital filtering to define any narrower passband of interest. This allows bandwidth switching to take place without any changes to the analog circuitry. Simultaneous processing of both wide and narrow modes of operation may be done in the digital signal processor (DSP) performing the digital filtering.

Patent CA-2239681-C (CA)
Inventor: HUANG XINPING
IPC: H04B1/30

Granted: 2007-08-21
Abstract: The present invention relates to the regeneration of in-phase (I) and quadrature (Q) signals in electronic devices commonly used in communication, radar and instrumentation electronics. The original signal of interest comprises two orthogonal components that are mathematically modelled using complex values, which are then decomposed into a real (I) and an imaginary (Q) component. These two components are orthogonal to each other and represent fully the signal of interest. The present method adaptively compensates for the gain and phase imbalances and DC offsets in I and Q signal regeneration. First, 3 phase shifted versions of the received signal, either down-converted to some intermediate frequency (IF) or at baseband, are digitised. Although the optimum phase shift between each version is 360°/3, any phase shift different than 0° and 180° is acceptable and no a priori knowledge of the phase shifts is required.  Based on these 3 digital signals representing 3 linear combinations of the I&Q  signal components, the regeneration algorithm projects these signals into a 3-dimensional space composed of the I signal subspace, the Q signal subspace, and another subspace, referred to as the noise subspace. The projection is performed using an eigen-decomposition method where the eigenvectors associated with the I and Q signal subspaces provide linear combination coefficients for regenerating the I&Q signals. Compensation for DC offsets is performed by removing an average DC offset on the phase and gain corrected I&Q signals. The regenerated digital I and Q  signals are then converted back to analog signals, when required.

Abstract: A system and method for providing calling party identification information to a called party in an intelligent network. A long distance calling card company maintains a subscriber database that includes preferred calling number data and calling name data for each subscriber. When a subscriber places a calling card call, the service provider looks up the subscriber's database record, retrieves the preferred calling number data, and sends the calling number data to the terminating end office. A calling name query from the terminating end office is routed to a database that includes data from the service provider's subscriber database. The caller's name is retrieved and returned to the terminating end office and displayed on the called party's display device, along with the calling number data, date, and time. By directing the calling name inquiry to the service provider's subscriber database, or to a database that includes relevant data from the subscriber database, the called party's caller ID display device is able to display both the calling party's identity and a valid call back number.

IPC: B22D11/01
Filed: 1997-06-05
Granted: 2006-08-01
Abstract: The invention relates to a strip casting plant with a circulating belt. In the cooling area, the belt is sucked against carriers by a negative pressure in the cooler.      Formerly used carriers were designed as supporting rollers and had a profiled surface, the profiling being substantially composed of grooves of a width which corresponded to the width of the portions of larger diameter. This could not sufficiently reduce thermal stresses. The strip curved up from the supporting roller. This worsened heat transfer and imprinted a profile corresponding to the upward curvature onto the thin cast strip. In the strip casting plant according to the invention it is envisaged to arrange the carriers in such a way that, with given mechanical properties of the circulating belt, a deflection that compensates for the thermal elongation takes place between the supporting surfaces.

Title: Method and apparatus of providing bit count integrity and synchronous data transfer over a channel which does not preserve synchronization
Inventor: TIEDEMANN EDWARD G JR
IPC: H04L9/12
Filed: 1997-06-11
Granted: 2004-06-08
Abstract: Synchronization and bit count integrity of a synchronous data stream is preserved end to end even as it is transmitted via a medium which does not preserve the synchronous nature of the synchronous data stream. A terminal equipment unit (100) produces a constant rate bit stream which is provided to a communications unit (110). The communications unit (110) produces a first data frame comprising a first set of bits from the constant rate bit stream and a first length field value. A second data frame is produced which comprises a second set of bits from the constant rate bit stream and a second length field. A third data frame is produced which comprises a third set of bits from the constant rate bit stream and a third length field value. The first, second, and third data frames are transmitted to a base unit (118) which places the first set of bits from the first frame into a queue (150). A set of fill bits equal to the maximum number of bits contained in any frame is then placed into the queue (150). The base unit (118) then determines the number of bits in the second set of bits of the third data frame, based on the first length field value and the third length field value. The base unit (118) overwrites excess fill bits in the queue (150) with the third set of bits. The number of excess fill bits is equal to the difference between the maximum possible number of bits which may be contained in any frame and the number of bits in the second set of bits.

Abstract: In a chamber R1 which accommodates a transmission device comprising a drive pulley 8, a driven pulley 9 and a belt 10, a cover 51 is provided to cover the lower peripheral portion of the drive pulley 8 along the periphery. The drive pulley is positioned below the driven pulley, and raised portions 52 which are used for the detection of the rotational speed of the drive pulley are provided on the periphery of the drive pulley. The end surface 51bs of the cover facing the inner wall 54 of the pulley chamber is positioned away from the inner wall with a clearance V therebetween. In a vehicular transmission which is constructed in this arrangement, the amount of lubrication oil that flows near to the periphery of the pulley which is positioned lower is comparatively small. Thus, this arrangement restricts agitation of the lubrication oil, which may be caused by the raised portions of the rotating pulley. Therefore, loss in the rotation of the pulley and oxidation and degradation of the lubrication oil are effectively prevented.
