Title: Absorbent members comprising a high surface area material for absorbing body liquids
Inventor: YOUNG GERALD ALFRED
IPC: A61F5/44
Filed: 1999-03-12
Abstract: Described are absorbent members useful in the containment of body liquids such as urine. These absorbent members comprise at least one osmotic absorbent (preferably a hydrogel-forming absorbent polymer) and a high surface area material, and have a high capillary suction capacity. For purposes of the present disclosure, capillary suction capacity is measured in terms of the member's ability to uptake liquid at high capillary heights, which are generally encountered when the member is positioned in an absorbent article.  In particular, capillary suction capacity is measured in terms of a member's capillary sorption absorbent capacity, which is measured in accordance with the Capillary Sorption method described in the Test Methods section.

Title: System based control of optical amplifier transmission functions
Inventor: THOMPSON WILLIAM A
IPC: H04B10/17
Filed: 2000-12-11
Abstract: Each of a series of optical amplifiers is arranged such that, in response to detecting particular stimuli occurring at an input or receipt of an adjustment start message from an upstream amplifier, adjusts certain amplifier parameters using small steps and completes the adjustment using large steps if it does not receive the adjustment start message within a predetermined period of time of starting the adjustment in response to detecting the stimuli. If the optical amplifier receives the adjustment start message, then it continues to perform the adjustment and completes the adjustment using large steps when it receives an adjustment done message from the upstream optical amplifier. At that point, the optical amplifier sends an adjustment done message to the next downstream amplifier if it is not the tail-end amplifier.

IPC: H04B1/707
Filed: 1999-07-14
Abstract: A spread spectrum receiver and method having narrow-band interference rejection of narrow-band jamming signals using digital signal processing frequency domain techniques. The method performed in the receiver includes transforming the received signal to a frequency domain signal and identifying narrow-band interference components in the frequency domain signal;  suppressing the identified narrow-band interference components by excising the identified narrow-band interference components from the frequency domain signal to produce an interference excised signal in the frequency domain, and storing in a memory frequencies corresponding to the identified narrow-band interference components; synchronizing a receiver code to a transmitter code in the frequency domain using the interference excised signal; generating coefficients for a time domain filter that includes notches at the frequencies corresponding to the excised narrow-band interference components and that jointly despreads and rejects narrow-band interference from the excised frequencies; applying the coefficients generated in the preceding step to the time domain filter; and despreading and filtering in real time in the time domain the received signal using the applied coefficients.

Title: A method and a circuit for recovering a digital data signal and a clock from a received data signal
Inventor: FINSETH NIELS CHRISTIAN
IPC: H04L7/027
Filed: 1999-11-23
Abstract: By application of a method for recovering a digital data signal (D out) and a clock signal (Ck out) from a received data signal (D in) consisting of a number of successive bits, a clock signal is produced from the received data signal by means of a resonator circuit (5). The recovered data signal is produced by sampling the received data signal with the recovered clock signal. The received data signal and the recovered clock signal are phase locked to each other so that the received data signal is sampled approximately in the centre of every bit. By phase locking the two signals to each other immediately prior to the sampling, the effect of varying time delays to which the two signals have been subjected individually on their way through the circuit is neutralised, and every sampling may be performed precisely within the very short time during which the data signal is stable.
