Title: Bis (dialkylmaleimide) derivative and polyetherimide for optical communications formed therefrom
Inventor: SUH DONG-HACK
IPC: C08G73/12
Filed: 1998-12-23
Granted: 2003-07-08
Abstract: A bis(dialkylmaleimide) derivative and a polyetherimide for optical communications, the polyetherimide formed therefrom. The polyetherimde has a high refractive index, so that when using such polyetherimide as a material for a core of an optical fiber, the range of the materials that can be selected for the cladding becomes wide. Also, a coating property and adhesion to a substrate are improved, thereby providing a good film forming property and thermal stability. Also, because the polyetherimide can minimize optical loss at a near infrared wavelength range, the polyetherimide is very useful as an optical material in the optical communications field adopting the light of near infrared wavelength.

Abstract: A receiver for receiving a cable and terrestrial digital signals of differing VSB modes where the data levels of the various signals have a desired relationship that enables simple data level slicing and error determination.  Some of the signals have sync levels that do not conform to the desired relationship and the receiver includes a comb filter for reducing interference when receivingan 8VSB terrestrial signal. The mode of the received signal is determined and a correction factor is applied to the syncs of the signals as needed to reestablish the desired relationship. Operation of the comb filter results in additional levels and a disruption of the desired relationship. For such cases, the comb filtered data levels are modified to make them a subset of the VSB 16 data levels. The modifications are accomplished in feedback paths of the phase tracker after the circuit equalizer and do not affect the data levels passed to the next stage.

Abstract: L'invention concerne un pare-reflets pour écran d'ordinateur comprenant des panneaux supérieur, latéral gauche et latéral droit de protection contre la lumière ambiante, dont chacun présente une surface saillante frontale, une surface frontale de protection pour l'écran, des bords latéraux gauche et droit et des bords avant et arrière. Une partie destinée à recevoir un contrepoids est placée sur l'écran et présente une première surface antidérapante. Un contrepoids ayant une seconde surface antidérapante peut être manuellement et sélectivement placé dans une pluralité de positions sur un axe longitudinal sur la partie destinée à recevoir un contrepoids. Les première et seconde surfaces antidérapantes sont en contact l'une avec l'autre de façon à maintenir le contrepoids dans la position sélectionnée. Il faut équilibrer le pare-reflets de l'écran dans une position sélectionnée sur l'écran, de telle sorte que les panneaux de protection supérieur, latéral gauche et latéral droit fassent saillie par rapport à la partie frontale de l'écran, au niveau des surfaces respectives supérieure, latérale gauche et latérale droite de l'écran, afin de protéger l'écran de la lumière ambiante. Dans un autre mode de réalisation, le panneau supérieur de protection comporte une couche externe sensiblement rigide et une couche élastique de matière facilement déplaçable disposée sur le panneau supérieur de protection à l'opposé de la surface saillante. Ladite couche élastique s'ajuste à la forme de la partie de l'écran avec laquelle elle entre en contact, ce qui a pour effet de fixer l'écran et de maintenir par conséquent le pare-reflets en place. Dans un autre mode de réalisation, les panneaux de protection gauche et droit sont sollicités soit par un élément élastique, soit par un élément ressort et entrent en contact par friction avec lesdites surfaces latérales gauche et droite de l'écran.

Abstract: Cellular surface receptors exist in an equilibrium between an inactive and active state. To date, prior art approaches to studying receptor function and screening receptors for new drugs focused on first identifying the endogenous ligand for the receptor (or a synthetic substitute) and then identifying antagonists to the receptor existing in an inactive structural conformation. It has now been recognized that very valuable information relevant to treatment of diseases caused by receptors can be directly obtained by identifying compounds which act as inverse agonists to constitutively activated forms of the receptors;  i.e., those in which the equilibrium has been shifted towards the active state. Methods to constitutively activate receptors are used to specify the genetic information coding for receptors which are then expressed in appropriate expression systems. Assays which measure the cellular response elicited by compounds acting on the receptors can identify both inverse agonists and agonists of the receptor. High throughout screening may be used to rapidly identify these compounds.  A particularly relevant feature is that modulators of receptor action can be identified with no prior knowledge of the endogenous ligand or receptor function. The method of the invention is particularly applicable to orphan receptors.

Granted: 2006-11-21
Abstract: A method and apparatus for controlling the transmission of signals from one or more of a plurality of mobile stations to a base station on a plurality of M multiple access channels. A power control information packet formed from a plurality of power control bits is transmitted from the base station to the one or more mobile stations. Each of the power control bits in the power control information packet has a position that is mapped to a selected access channel and to a time offset within the selected access channel. The power control information packet is received at a first mobile station. A message is then transmitted from the first mobile station to the base station on a first access channel and at a first time offset associated with the first access channel. The message is transmitted from the first mobile station at a power level determined in response to a first power control bit in the power control information packet. The first power control bit is located in a first position in the power control information packet, the first position being mapped to the first access channel and the first time offset. In one embodiment, access-related functions involve transfer of hashing values generated from information particular to mobile stations.
