摘要:
The present invention relates to a copolymer derived from the polymerization of a) at least one cationic monomer of formula (I), where in R1 is hydrogen or methyl, R2 is hydrogen or C1-C4alkyl, R3, R4 and R5 are independently from each other hydrogen or C1-C4alkyl, n is a integer from 1-5, and Y is a counterion, and b) as least one monomer of formula (II) wherein R6 signifies hydrogen or methyl, and R7, R8 and R9 signify independently from each other hydrogen or C1-C4alkyl, with the proviso that at least one of the substituents R6, R7, R8 and R9 and C1-4alkyl and c) optionally at least one cross-linking agent, which contains at least two ethylenically unsaturated moieties, as well as to their use in personal care product and to the personal care products.
摘要:
An antenna is provided with an electronic component or circuit that has a value corresponding to properties of the antenna. A read mechanism reads the value and sets an operational status of a transceiver based on the value. In one embodiment, electronic component is a resistor having a value that identifies the antenna properties. A table may be used to correlate resistor values to different types of antennas or sets of antenna properties. Alternatively, the circuit can be embodied in a microchip that provides a response to a challenge sent by the read mechanism. The response encodes the properties of the antenna. The encoding scheme includes values from the challenge. Alternatively, the response is a code that is indexed into a table of antenna properties. In one embodiment, the antenna is connectorized.

A lock detection circuit operatively associated with a phase-locked loop indicates when a feedback clock signal is locked to a reference clock signal. The lock detection circuit counts the number of rising and falling edges of the feedback clock signal that are detected between rising edges of the reference clock cycle. The lock detection circuit counts the number of consecutive valid cycles of the reference clock signal during which a single rising edge and a single falling edge of the feedback clock signal are detected. Lock detection circuit asserts a lock signal when the number of consecutive valid cycles counted exceeds a predetermined number. Where the lock detection circuit indicates locked signals and then detects a reference clock cycle that is not valid, lock detection circuit continues to indicate lock if the next reference clock cycle is valid relative to a skewed feedback clock signal.

摘要:
Liquid dispersion polymer compositions which comprise microparticles of a hydrophilic, water soluble or swellable polymer, preferably an acrylic-based polymer, dispersed in a silicone polymer fluid and an oil-in-water surfactant, are useful to prepare microparticulate thickening systems to thicken aqueous or aqueous/organic compositions, particularly for use in personal care and pharmaceutical formulations.
摘要:
A multi-feature stroller (100) includes several unique features. The stroller, which has a forward sub-frame (104) and a rearward sub-frame (108) that is foldable upon itself, provides a napper bar (150) which extends outwardly from the forward sub-frame (104). The napper bar (150) provides a locking mechanism (254) which engages one of two locking tongues (190) extending from an underside of a car seat (160). Accordingly, the car seat (160) may be carried by the stroller (100) in a forward-facing position and a rearward-facing position. The napper bar (150) is moveable between an extended position and a recessed position by actuating a release mechanism (302). A fold down mechanism (130) is connected between the rear sub-frame (108) and the forward sub-frame (104) when actuated causes the sub-frames to fold into a collapsed position and simultaneously causes the napper bar to fall to its recessed position. The stroller (100) is also provided with an adjustable foot rest (120) that is slidable upon the forward sub-frame. A cross member (116), which extends between the forward sub-frame, supports the foot rest in one of two positions. The stroller is also provided with a lock adjustment (140) which allows height and length adjustment between a handle bar (134) and a push bar (132) that is connected to the rear and forward sub-frames. These features can be provided singly or in various combinations with one another.
