Title: Forward link power control in a cellular system using nt/i0 values
Inventor: BENDER PAUL E
IPC: H04W56/00
Filed: 1999-02-19
Granted: 2010-06-22
Abstract: A system and method is taught for controlling the power level of transmissions within a communication system having a base station, a mobile station, a communication channel, and a pilot channel. The mobile station determines a signal strength value according to a communication signal received by way of the communication channel. A pilot channel signal is determined according to a pilot signal transmitted by way of the pilot channel. The signal to noise ratio of the communication signal is determined according to the determined signal strength value and the pilot channel signal. The power level of a transmission is controlled according to the signal to noise ratio. The noise level in a communication channel within the communication system is estimated.  The pilot channel signal includes pilot energy and pilot noise components. The pilot energy component is removed to provide a remaining pilot signal.  Communication system operations are controlled according to the remaining pilot signal. The power levels of transmissions are controlled by determining the signal to noise ratio of a signal within the communication channel and determining a difference signal. The difference signal is formed by determining the difference between determined and desired signal to noise ratios. The difference signal is transmitted between the base station and the mobile station. The pilot channel has at least one frame and the power control signal is inserted into the frame. Thus, information representing the strength of the communication signal is transmitted to the base by way of the pilot channel within the frame. The pilot channel can have two information frames for transmitting the power control signal a plurality of times.

Patent CA-2310256-C (CA)
Inventor: VAN DEN BRINK CHRISTOPHER RALP
IPC: B62K21/10
Filed: 1998-11-10
Granted: 2008-03-11
Abstract: The invention relates to a vehicle (1) provided with a frame having two frame sections (3, 4) which are able to tilt with respect to one another. An opposite lock power transmitter (50) is connected to a steerable front wheel (13). The opposite lock power transmitter (50) is controlled as a function of the tilting moment on the frame sections (3, 4). By this means application of opposite lock is achieved, as a result of which the tilting section of the vehicles "drops into the bend" more rapidly and as a result of which increased manoeuvrability is obtained. The opposite lock power transmitter (50) can be used on vehicles having an active tilting system with drive means, such as, for example, hydraulic tilting cylinders (9, 9'), which are controlled by a sensor depending on the radius of the bend (24). The tilting moment generated by the tilting cylinders (9, 9') can optionally serve as a control signal for the opposite lock power transmitter (50). As a result of the active application of opposite lock, the tilting cylinders (9, 9') can be of relatively small construction.

Inventor: TROUT JAMES EARL
IPC: C07C29/80
Filed: 1998-12-22
Granted: 2005-05-17
Abstract: Methods of removing a lower alkyl alcohol from a polyester mixture of polyol fatty acid polyester and lower alkyl alcohol comprise (a) contacting the polyester mixture with a stripping mixture comprising an inert stripping gas, up to about 10,000 ppm lower alkyl alcohol and up to about 2000 ppm oxygen, wherein at least a portion of the lower alkyl alcohol is transferred from the polyester mixture to the stripping mixture, thereby increasing the concentration of lower alkyl alcohol in the stripping mixture, and (b) separating the stripping mixture from the polyester mixture. The methods further comprise (c) compressing the stripping mixture to increase its pressure, (d) cooling the stripping mixture to reduce its temperature thereby condensing at least a first portion of the lower alkyl alcohol to a liquid, (e) separating condensed lower alkyl alcohol from the stripping mixture to reduce the amount of lower alkyl alcohol in the stripping mixture to a range of from about 1 ppm to about 10,000 ppm, and (f) directing the resulting stripping mixture to an expansion turbine in which the temperature and pressure of the stripping mixture are reduced. Energy resulting from the decrease in the stripping mixture temperature and pressure in the expansion turbine is used to compress the stripping mixture separated from the polyester mixture. The methods are used to remove lower alkyl alcohol from polyol fatty acid polyesters. This invention provides an energy efficient method of removing the lower alcohol from the stripping mixture.

Chaque alvéole contient environ 100 cartouches individuelles contenant chacune des monodoses emballées d'un médicament précis ou d'un autre article médical tel que des seringues. Chaque module de stockage comporte un éjecteur qui éjecte les médicaments ou articles sélectionnés vers une gouttière d'approvisionnement. Les emballages se trouvant dans la gouttière sont transportés vers un collecteur central qui les distribue dans un bac réceptacle qui a été placé en dessous du collecteur et qui est identifié de façon spécifique pour un patient déterminé. Les informations se rapportant aux fournitures ou aux médicaments destinés à un patient défini sont conservées dans une base de données du système et servent à déterminer les fournitures ou médicaments particuliers distribués dans le bac considéré. Pour garder trace des bacs et des médicaments, on utilise un système de code barres s'intégrant à un système cohérent d'informations et de gestion. Ceux des médicaments ou des fournitures qui ne sont pas disponibles dans le système de distribution automatique sont fournis depuis un chariot de médicaments de complément qui a été préalablement chargé des médicaments de complément au vu des informations fournies par un ordinateur de gestion. Les bacs remplis sont transférés vers un chariot à médicaments qui n'est accessible qu'à la suite d'un signal de commande, une fois qu'on s'est assuré de la pertinence entre un patient particulier et le bac qui lui est associé. Une infirmière ayant accès au bon bac et au secteur de ce bac retire les médicaments du chariot et les administre au patient.

Abstract: A vehicle restraint for a truck loading dock includes an actuator that rides up with a carriage (20) to sense that a truck's ICC bar is within a predetermined region before fully extending a restraining member (28) to engage the bar. The carriage and restraining member are raised and lowered by a drive unit (42), such as a cable (60) extending from a winch. The winch may be attached directly to the carriage, or optionally remotely mounted to the dock. One end of the cable connects to a spring (64) that compensates for incidental vertical movement of the ICC bar caused by the truck being loaded or unloaded. Large downward movement of the ICC bar is accommodated by a clutch (50) associated with the winch. For large upward movement, the winch automatically restarts to pull the carriage up to meet the new height of the bar. An optional ICC bar deflector mounted at the base of the dock, along side the carriage, wedges underneath an exceptionally low ICC bar as the truck backs into the dock. The deflector guides and lifts the low bar above the actuator to prevent premature and uncontrolled extension of the restraining member.
