Abstract: An absorbent article having both outwardly extending and upwardly extending side cuffs is disclosed. The article has a perimeter defined at least in part by a pair of oppositely disposed ends and oppositely disposed sides that extend substantially between the ends. A pair of side flanges extends from a proximal portion adjacent an absorbent structure to a distal portion proximate one of the article sides. Each side flange has a base element, an outer zone disposed adjacent the perimeter and an inner zone disposed between the outer zone and the absorbent structure. There is an elastically extensible element having a width sufficient to span at least the inner zone and a portion of the outer zone, a thickness, and a length. Each elastically extensible element is laminated to the cover material to form a cuff laminate. Each cuff laminate is attached to the base element of the side flange in the outer zone, but each is unattached to the base layer in the inner zone. Finally, the cover is attached to the absorbent structure, at least in a central region of the article. Thus, at least a portion of each cuff laminate is deflected away from the base element of each side flange proximate the inner zone when the elastically extensible element is in a relaxed state.

Abstract: The invention provides methods and apparatus for processing information, e.g., audio, video or image information, for transmission in a communication system. In an illustrative embodiment, interference characteristics are determined for a set of n channels to be used to transmit audio information bits, where n is greater than or equal to two. The audio information bits are separated into n classes based on error sensitivity, for example, the impact of errors in particular audio data bits on perceived quality of an audio signal reconstructed from the transmission. The classes of bits are then assigned to the n channels such that the classes of bits having the greatest error sensitivity are transmitted over the channels which are the least susceptible to interference. The interference characteristics associated with the n channels can be determined by, for example, measuring interference levels for one or more of the channels, or obtaining information regarding known interference levels for one or more of the channels. The channels may correspond to different frequency bands, time slots, code division slots or any other type of channels. The invention can provide UEP  for different classes of audio information bits even in cases in which the same convolutional code, or the same complementary punctured pair convolutional (CPPC) code pair, is used to encode the classes. The assignment of the classes of bits to the channels, as well as the characteristics of the classes a.nd the channels, may be fixed or dynamic.

Abstract: A method and apparatus are disclosed for determining the data rate of a received signal in a communication system utilizing code division multiple access (CDMA) techniques. The well-known Viterbi decoding-based rate detection approach is combined with the conventional repetition pattern-based rate detection approach. The hybrid approach possesses the advantages of both prior approaches, without their disadvantages. The computationally efficient repetition pattern-based data rate detection approach, while not as reliable as the Viterbi decoder-based data rate detection approach, provides reliable data rate detection most of the time. The repetition-pattern data rate detection approach is used as long as a predefined reliability metric is satisfied, and only uses the more computationally intensive Viterbi decoder-based data rate detection approach when detection reliability may be compromised. Under the hybrid rate detection scheme, a decision variable based on repetition patterns is initially formed and a decision is made on the data rate if the decision variable is in a reliable region. Otherwise, the Viterbi decoding-based rate detection scheme is employed

Abstract: A reflective article has a multilayer film covering a patterned retroreflective layer. In one embodiment the patterned retroreflective layer includes a separate indicia layer covering a retroreflective substrate. The indicia are substantially hidden under normal viewing conditions but easily detectable under retroreflective lighting conditions. Various types of retroreflective layers are disclosed. The article can also include microstructured relief patterns which produce holographic images under ambient lighting but which disappear under retroreflective conditions. The multilayer film includes alternating layers of at least a first and second polymer, and has a relatively high reflectivity for normally incident light within a first spectral range which is approximately coextensive with the visible spectrum, and a relatively low reflectance for normally incident light within a second spectral range. The second spectral range can include a transmission window of 15 % or less fractional bandwidth located at least partially in the visible spectrum. Fil m constructions are disclosed which achieve sharper spectral transitions than previously attainable. Film constructions are also disclose d which preserve such sharp transitions even at high entrance (tilt) angles.
