PC Tel, Inc. - San Jose CA

International Classification:

H04B 1404

US Classification:

375242, 370523

Abstract:

The receiver of a PCM modem utilizes the V. 90 TRN training signal for detecting whether any of the six slots of the received signal may be subject to alternating robbed bit signaling (ARBS), and what the alternating robbed bit signaling pattern may be. This is accomplished by accumulating the received level over a plurality of frames for each slot and by comparing the received levels for each slot to an average level for that slot. If the difference between the received levels and the average levels exceeds a threshold, the slot is determined to be subject to ARBS. Where a slot is subject to ARBS, DIL sequence signals for frames of the alternating robbed bit signaling slot having LSB=0 and LSB=1 are accumulated separately (if available) in order to generate two translation tables (TRT , TRT ) for that slot. Where the DIL sequence is found only in the frames having the alternating robbed bit signaling slot having LSB=0 or having LSB=1, only one translation table can be generated. Different algorithms are provided for designing a constellation for the alternating robbed bit signaling slot depending on (a) whether two translation tables were generated for the slot, (b) whether the frame-to-TRT correspondence is known, and (c) where only one translation table is generated, whether the translation table generated was TRT or TRT.

International Classification:

H04B 516

US Classification:

375222, 370523

Abstract:

A method for determining the encoding law of an incoming signal in a network which possibly contains an A- or -A conversion includes obtaining digital impairment learning (DIL) probing data, generating an ordered table of levels therefrom, using the table to find two functions, and using a logical analysis of the functions to determine the encoding law of the signal. A first function is a maximum from the values DL(i) and the threshold Th which are less than T(i), with T(i)=a+bi, and DL(i)=L(i+ )- L(i) with L(i) being the DIL signal corresponding to the transmitted Ucode=i. A second function Q is defined by: where DLm(i) is the median value of a windowed group of values for DL(i) where i ranges from i5 to i6, Ly=i6-i5-1, and S is a mean of a windowed group of slopes, wherein each slope relates to the difference between certain DLm(i) values.

A first function is a maximum from the values DL(i) and the threshold Th which are less than T(i), with T(i)=a +bi, and DL(i)=L(i+16)-2L(i) with L(i) being the DIL signal corresponding to the transmitted Ucode=i. A second function Q is defined by: where DLm(i) is the median value of a windowed group of values for DL(i) where i ranges from i to i , Ly=i -i -1, and S is a mean of a windowed group of slopes, wherein each slope relates to the difference between certain DLm(i) values.

International Classification:

A61K 8/00

US Classification:

424049000

Abstract:

In various embodiments, the present invention provides a tooth whitening composition comprising a peroxide composite and an orally acceptable carrier. The peroxide composite comprises a peroxide compound and a porous cross-linked polymer, preferably in the form of a microporous particulate. The peroxide compound can be sorbed onto the porous crosslinked polymer. The porous cross-linked polymer may comprise a polymerized polyunsaturated monomer selected from polyacrylates, polymethacrylates, polyitaconates, and mixtures thereof. The carrier can be non-aqueous, and can comprise a film forming material. Methods are also provided for whitening a tooth surface with the tooth whitening compositions.
