Title: Systemes liquisolides et leurs procedes de production
Inventor: BOLTON SANFORD M
IPC: A61K9/14
Filed: 1997-06-09
Granted: 2003-10-28
Abstract: Les systèmes liquisolides consistent en des formes pulvérulentes d'une fluidité et d'une compressibilité acceptables de médicaments liquides. Selon le concept des systèmes liquisolides, des médicaments lipophiles liquides ou des médicaments hydro-insolubles, dissous dans des solvants non volatils appropriés, peuvent être convertis en poudres coulantes et facilement compressibles, par simple mélange avec des excipients en poudre sélectionnés appelés matières de support et matières d'enrobage. On peut faire un croquis schématique des différentes étapes du procédé. Plusieurs catégories de cellulose microcristalline ou amorphe peuvent être utilisées comme matière de support, tandis que des poudres de silice à particules très fines peuvent être utilisées comme matière d'enrobage. En se fondant sur la théorie selon laquelle les matières de support et d'enrobage ne peuvent retenir qu'une certaine quantité de liquide tout en conservant en même temps une compressibilité et une fluidité acceptables, on a mis au point un nouveau modèle mathématique de formulation permettant de calculer les quantités maximales de matières de support et d'enrobage nécessaires pour produire des mélanges liquide/poudre d'une fluidité et d'une compressibilité acceptables.

Title: Adaptive rate control for digital video compression
Inventor: LEE CHONG U
IPC: H04N7/30
Filed: 1997-10-09
Granted: 2006-12-19
Abstract: A system and method for adaptively controlling the encoded data rate in a data compression system. The system and method sets up alternative encoded bit streams for each segment of data and selects the alternative that would produce the bit rate closest to a predetermined target bit rate for transmission. Each segment of the video input is quantized by a set of quantizers (20a-20c) to produce a plurality of quantized segments. Each quantized segment is variable rate encoded by a variable-length encoder (22a-22c) based on a quantization index to produce an alternative encoded bit stream. A set of rate measurers (24a-24c) measure the data rate that would be required to transmit each alternative encoded bit stream, and comparator (30) compares the measured rates with a predetermined target bit rate. The encoded bit stream having a rate closest to the target bit rate is provided to a rate buffer (34) in preparation for transmission. Having processed one segment of data, the system and method then updates its parameters for processing the next segment of data. A target bit rate update element (38) determines an updated target bit rate based on the rate buffer status. In addition, a quantization index update element (36) generates new quantization indices for processing the next segment of data.

Granted: 2003-10-14
Abstract: The invention concerns an inverter or an output filter for inverters. The output current of an inverter for higher levels of power generally has a whole series of current harmonics. Those harmonics are troublesome and they occur in an unacceptable fashion in particular when a relatively high level of power has to be fed into a network by way of inverters. Therefore the object of the invention is to eliminate the above-mentione d disadvantages, so that only current with very low and if possible no harmonics at all is still fed into the public supply network. The inventi on further seeks to provide that the dc voltage intermediate circuit of the inverter is stabilised in respect of electrical potential (voltage value in relation to the housing, earth or the three-phase system). 1. An inverter for producing an alternating or three-phase current from a dc voltage comprising - a dc voltage intermediate circuit and - on the output side an output choke (L A), - wherein harmonics occurring on the output side are coupled into the dc voltage intermediate circuit.

Title: System and method for automatic notification of upcoming delivery of a mail item
Inventor: PINTSOV LEON A
IPC: G07B17/00
Filed: 2000-06-23
Granted: 2003-12-30
Abstract: In accordance with the present invention, when a mailer generates a mail piece, for example using mail generation software in a PC metering system, the mail generation software accesses a database of mailing addresses. This database also contains e-mail address of recipients in the mailing list (address database). If a mailer wants to send advance notice to a recipient that a mailpiece has been sent to the recipient, the mailer can choose this option automatically and use a unique mailpiece ID as an identifier of the upcoming mailpiece. (The mailpiece ID can be generated specially for this purpose and serve as a reference point for the mailer and the recipient). This can be particularly advantageous in a legal environment, when there is a need for timely distribution of information as well as the need for distribution of legally valid hard copy documents. The unique ID number may be printed in plain text in the address block and cryptographically encoded within the DPM. This ID number can be used to provide references and links to other relevant documents as well. When the DPM is scanned upon induction into a postal distribution network, system includes recognition of the recipient's e-mail address and automatically sends notice of intended delivery to the recipient. The notice may also include an estimated date of delivery.
