Abstract: A self-provisioning names database adds new names to a database for associating names to calling address data in a caller identification with name delivery service. A new caller's name is added to the database each time the newcaller places a call to a service subscriber. The database reaches only a nominal size in accordance with Perado's rule that approximately 80% of incoming calls to a subscriber will be from the same small group of callers. Alternatively or in addition, a new party's name is added to the database each time a service subscriber places a call to a party whose name is not already in the names database. Caller names that have been stored in the database and not retrieved for a long period of time are discarded to store new names. Also, the database may periodically request updated data for a stored name, for example, to determine if a different telephone number or address has been assigned to the given name data.

Title: Digital television receiver with adaptive filter circuitry for suppressing ntsc co-channel interference
Inventor: LIMBERG ALLEN LEROY
IPC: H04N5/44
Filed: 1998-06-19
Granted: 2001-09-04
Abstract: Co-channel interference accompanying multiple-level symbols in a digital receiver, such as a digital television receiver, is suppressed by using a first comb filter to reduce the energy of the co-channel interference before data slicing. The first comb filter incidentally precodes the symbol decoding results generated by the data slicing. A second comb filter postcodes the precoded symbol decoding results from the data slicing to generate corrected symbol decoding results. The symbol precoding of the input symbol stream results from differential delay and first linear combination of the differentially delayed terms. The postcoding of the symbol stream recovered by data slicing results from second linear combination of the symbol stream with delayed result of the second linear combination, and is performed in accordance with a modular arithmetic. One of the first and second linear combinations is subtractive, and the other is additive. The results of the second linear combination are the corrected symbol decoding results.

Title: Control channel for non-terrestrial cellular mobile telecommunication station
Inventor: MCKENNA DANIEL B
IPC: H04B7/185
Filed: 1997-08-25
Granted: 2004-01-20
Abstract: The multidimensional cellular mobile telecommunication system extends the usage of existing cellular mobile telecommunication radio frequencies allocated for ground-based communications to non-terrestrial mobile subscriber stations by adding an overlay of non-terrestrial cells of predetermined geometry and locus in space to the existing ground-based cellular cell site network. The polarization of the signals produced by the non-terrestrial antenna elements is a polarization that is different than and preferably substantially orthogonal to the polarization of the cellular radio signals produced by the ground-based antennas, such as a horizontal polarization, to thereby minimize the possibility of interference with the vertically polarized ground-based radio signals. Furthermore, the control signals exchanged between the non-terrestrial mobile subscriber stations and the non-terrestrial cell site controller are architected to avoid the possibility of interference with ground-based cell site transmitter-receiver pairs. In particular, the control channels used for the non-terrestrial mobile subscriber stations are selected such that the control signals transmitted in these channels are unrecognizable to the ground-based mobile subscriber stations and cell site transmitter-receiver pairs, so that even if broadcasts from a non-terrestrial mobile subscriber station reach a ground-based mobile subscriber station or cell site receiver, they cannot be interpreted and are rejected out of hand.

Abstract: Non-invasive methods and kits are provided for obtaining biological samples of mammary fluid or mammary fluid components by administering oxytocin or an oxytocin analogue to a mammalian patient to stimulate expression of mammary fluid. The oxytocin is preferably administered intranasally and causes myoepithelial contraction of target alveolar-ductal tissues of the breast. During or after mammary fluid expression, a biological sample is collected in the form of whole mammary fluid, whole cells or cellular components, other selected liquid or solid fractions of the mammary fluid, purified or bulk proteins, glycoproteins, peptides, nucleotides or other desired constituents of mammary fluid. Methods and kits are also provided for determining the presence or amount of a breast disease marker in biological samples of mammary fluid or mammary fluid components. Samples obtained according to the above sample collection methods are assayed to determine the presence and/or amount of a breast disease marker, for example a breast cancer marker such as CEA, HMFG, MCA, vasopressin, or cathepsin D, in the sample. Cellular samples obtained according to the above sample collection methods are also examined microscopically for cytological evidence of breast disease.
