Title: Method of Promoting Nitrogen Retention in Humans
Inventor: NISSEN STEVEN L
IPC: A61K31/365
Filed: 1993-12-09
Abstract: Nitrogen retention in human subjects is promoted by administering .beta.-hydroxy-.beta.-methylbutyric acid (HMB). The amount of HMB administered is effective to conserve protein as determined by reduction in urinary nitrogen. The method can be used with patients having a negative nitrogen balance due to disease conditions, and also with normal elderly persons who are subject to protein loss. The HMB may be administered orally or by intravenous infusion.

Inventor: CLEAR SANDRA H
IPC: A61F5/44
Filed: 1993-08-23
Abstract: Absorbent articles such as disposable diapers, incontinent briefs, diaper holders, training pants, and the like, that provide dynamic fit about the wearer by the use of elasticized hip panels. Such absorbent articles comprise a liquid pervious topsheet; a liquid impervious backsheet; an absorbent core disposed between the topsheet and the backsheet; elasticized side panels positioned in the side panels of the back waist region; and an elasticized hip panel positioned in the central region of the back waist region. The elasticized hip panel comprises a stretch laminate comprising one or more elongatable components and an elastic hip panel member that are mechanically stretched to allow expansion of the stretch laminate beyond the original planar state of the diaper in the lateral direction. By adding stretch to the middle-back of the absorbent article, the absorbent article is capable of expanding in the back waist region thereby creating a more three-dimensional fit to better contour the hips and buttocks and to more completely wrap the wearer's hips and buttocks. In an alternative embodiment, a single elastic hip panel member is positioned in most of the central region of the back waist region with the stretch laminate being mechanically stretched in selected zones or preferably over the entire area of the elastic hip panel member. The absorbent core is either stretchable or preferably not attached to the stretch laminate in the mechanically stretched zones to not encumber the stretch of the stretch laminate. The topsheet is also preferably stretchable.

Filed: 1994-10-13
Abstract: Détecteur de corrélation pour récepteurs de communication AMDC pouvant établir une synchronisation à grande vitesse, peut extraire des composantes en corrélation mutuelle et assurer un suivi extrêmement précis. Le signal reçu (21) est envoyé à un filtre adapté (43) lorsque la synchronisation initiale est établie. Lorsqu'un circuit (45) d'estimation de synchronisation considère que le filtre (43) détecte la synchronisation le circuit de commutation (43) envoie le signal (21) à des multiplicateurs (47, 48) et remet à zéro un générateur (29) de codes commandé en tension et un générateur (30) de répliques de codes à spectre étalé. Une fois la synchronisation établie, le signal à spectre étalé est détecté de manière quasi synchrone, le signal reçu détecté de manière quasi synchrone est multiplié par des codes répliques présentant des phases avancées et retardées, et les signaux de détection de corrélation sont extraits des résultats de la multiplication. Des composantes carrées sont générées, additionnées les unes aux autres en phases opposées, et moyennées dans le sens temporel. Ledit signal à spectre étalé reçu est multiplié par les codes dont les phases sont synchrones, et les résultats sont intégrés par l'intermédiaire de puces. Après le traitement de moyennage, le signal est modulé à l'inverse au moyen du signal d'identification des données reçues obtenues par compensation de l'erreur de phase du signal reçu de manière à générer un signal d'erreur de phase. Le générateur de codes répliques est commandé par une horloge dont la phase est commandée par le signal d'erreur de phase.

Title: Video optimized media streamer with cache management
Inventor: BELKNAP WILLIAM RUSSELL
IPC: G06F12/00
Filed: 1995-07-07
Abstract: A data storage system includes a mass storage unit storing a data entity, such as a digital representation of a video presentation, that is partitioned into a plurality N of temporally-ordered segments. A data buffer is bidirectionally coupled to the mass storage unit for storing up to M of the temporally-ordered segments, wherein M is less than N. The data buffer has an output for outputting stored ones of the temporally-ordered segments. The data storage system further includes a data buffer manager for scheduling transfers of individual ones of the temporally-ordered segments between the mass storage unit and the data buffer. The data buffer manager schedules the transfers in accordance with at least a predicted time that an individual one of the temporally-ordered segments will be required to be output from the data buffer. When employed with a media streamer distributed data buffer management techniques are employed for selecting blocks to be retained in a buffer memory, either in a storage node or in a communication node. These techniques rely on the predictable nature of the video data stream, and thus are enabled to predict the future requirements for a given one of the data blocks.

Inventor: HIRSHFIELD EDWARD
IPC: H04B1/04
Filed: 1995-10-11
Abstract: Disclosed is a method for operating a communications signal transmitter and apparatus for carrying out the method. The method includes the steps of receiving a communications signal;  sensing  a  signal  strength  of  the  received communications signal, the signal strength being indicative of the current user demand; adjusting an output of a power supply that supplies operating power to a communications signal transmitter amplifier in accordance with the sensed signal strength so as to increase the output of the power supply when the sensed signal strength increases and to decrease the output of the power supply when the sensed signal strength decreases;  and amplifying the received communications  signal  with  the  communications  signal transmitter amplifier. The step of sensing may include a step of subtracting a noise component from the received communications signal. The step of adjusting includes the steps of setting the duty cycle of a pulse width modulated signal  as  a  function  of  at  least  the  sensed  signal strength; driving a switch with the pulse width modulated signal to chop a primary DC source into an AC signal; and synchronously rectifying the AC signal with an inverse of the pulse width modulated signal to provide a DC output from the power supply for supplying the operating power to the  communications  signal  transmitter amplifier.  In a presently preferred embodiment of this invention the switch is comprised of a field effect transistor (FET) that is coupled  between  the  primary  DC  power  source  and  a synchronous rectifier.  In this embodiment the step of driving includes a step of employing a boot strap capacitor that is coupled between the synchronously rectified AC signal and a predetermined bias potential to enhance the pulse width modulated signal that is applied to a gate of the FET.
