Patent TW-396308-B (TW)
Title: Document delivery system
Inventor: SMITH JEFFREY C
IPC: G06F21/62
Filed: 1998-03-31
Granted: 2000-07-01
Abstract: A document delivery architecture dynamically generates a private Uniform Resource Locator (URL) to distribute information. Each private URL(""PURL"") uniquely identifies an intended recipient of a document, the document or set od document to be delivered, and (optionally) other parameters specific to the delivery process. The intended recipient of a document uses the PURL to retrieve the document. The server, upon retrieval of the document, customizes the behavior of the retrieval based upon attributes included in the PURL, as well as log information associated with the retrieval in a data base. This architecture and usage of PURLs enables secure document delivery and tracking of document receipt. A method and system are provided for secure document delivery over a wide area network, such as the internet. A sender directs a Delivery Server to retrieve an intended recipient's public key. The Delivery Server dynamically queries a certificate authority and retrieves the public key. The public key is transmitted from the Delivery Server to the sender. The sender encrypts the document using a secret key and then encrypts the secret key using the public key. Both encrypted document and encrypted secret key are uploaded to the Delivery Server, and transmitted to the intended recipient. The intended recipient then uses the private key associated with the public key to decrypt the secret key, and uses the secret key to decrypt the document. In an alternaive, equally preferred embodiment of the invention, the sender uses the public key to encrypt the document. In yet another embodiment, the server transmits the document to the Delivery Server for encryption.

Title: Method and apparatus for air ionization
Inventor: PITEL IRA J
IPC: H05F3/06
Filed: 1999-01-28
Granted: 2001-05-01
Abstract: Ionizing method and apparatus includes a pair of inverters to supply ionizing voltages to ionizing electrodes only during alternate halves of a duty cycle in which one inverter is actuated to operate at high oscillating frequency while the other inverter is inactive, and thereafter in an alternate half of the duty cycle in which the one inverter is inactive and the other inverter is actuated to operate at high oscillating frequency. Each inverter includes a return current path that combines in a common return path in which return currents may be monitored for selective control of one or both of the inverters. Small step-up transformers and other components operating at high oscillation frequency promote confined packaging of high voltage generators for convenient mounting adjacent a pair of ionizing electrodes to reduce lengths of heavily-insulated high-voltage cables between generators and electrodes. Each electrode only operates on one polarity of high voltage derived from half-wave rectified high-frequency oscillations during the actuation of the associated inverter. Closely-spaced mounting of the electrodes adjacent a web of material having net electrostatic charge to be neutralized facilitates alternately supplying ions of each polarity from separate ones of the electrodes to neutralize charge on the web.

Title: Method and device for the automatic positioning pattern pressing and pasting of plastic tiles
Inventor: TSAI LANG-FU
IPC: B29C59/04
Filed: 1999-10-07
Granted: 2000-11-11
Abstract: This invention relates to a method and device for the automatic positioning pattern pressing and pasting of plastic tiles. The device consists of a base frame, pattern pressing roller module, plastic tape feeding control roller module, position mark sensing module, plastic tape tension balance module, and plastic tape feeding module. When plastic tiles are undergoing positioning pattern pressing and pasting processes, rotational speed of the pattern pressing roller is set firstly and rotational speed of the tape feeding control roller is then set. Afterward, angular zero position of the pattern pressing roller is randomly set by a computer controller and then a computer is used to partition and orient many angular position. When the pasting of the pressed pattern starting, comparison is made between angular position signal and position mark signal of the printed plastic tape by a computer controller to obtain time difference, and then tape distance difference by calculation. Therefore, plastic tape feeding roller speed can be adjusted in accordance with the adequate speed distribution curve derived from the speed compensation calculated from tape feeding control roller speed at that time by a control computer. This procedure ensures angular position and mark position on the tape being synchronous at all time. The deviation between pressed pattern and printed pattern on the plastic tape is further input into a computer which automatically regulates angular zero position of each revolution for the pattern pressing roller and thus overlaps pattern of the pattern pressing roller and printed pattern. Finally, the process enters into normal position correction mode and operates automatically and continuously.

Title: Method and apparatus for network control
Inventor: ZIKAN KAREL
IPC: H04L12/56
Filed: 1999-10-21
Granted: 2002-07-11
Abstract: In a data communication system having network traffic with flows, a network traffic director system using router modules. The router modules direct traffic based on optimizing a merit function or penalty function to reduce costs of congestion for stochastically changing demands and flows in the data communication system. The router modules exchange values with neighboring router modules. Based on the exchanged values and values local to a router module, flow conditions are checked and if necessary the local values are adjusted until the flow conditions are satisfied or a time period expires. Adjustments are associated with optimizing a merit function or penalty function. Based on the adjusted values, the router module adjusts parameters to be used to direct packets of the network traffic flows to other router modules or other destinations within the data communication system. An aggregation scheme is used for reducing the number of values stored in a single router module.

Title: Pharmaceutical composition of orally administered controlled drug delivery system providing temporal and spatial control
Inventor: TALWAR MARESH
IPC: A61K9/22
Filed: 1999-11-16
Granted: 2005-03-21
Abstract: A pharmaceutical composition in the form of tablets or capsules provides a combination of temporal and spatial control of drug delivery to a patient for effective therapeutic results. The pharmaceutical composition comprises a drug, a gas generating component, a swelling agent, a viscolyzing agent, and optionally a gel forming polymer. The swelling agent belongs to a class of compounds known as superdisintegrants (e.g., cross-linked polyvinylpyrrolidone or sodium carboxymethylcellulose). The viscolyzing agent initially and the gel forming polymer thereafter form a hydrated gel matrix which entraps the gas, causing the tablet or capsule to float so that it is retained in the stomach or upper part of the small intestine (spatial control). At the same time, the hydrated gel matrix creates a tortuous diffusion path for the drug, resulting in sustained release of the drug (temporal control). A preferred once daily ciprofloxacin formulation comprises 69.9% ciprofloxacin base, 0.34% sodium alginate, 1.03% xanthan gum, 13.7% sodium bicarbonate, 12.1% cross-linked polyvinylpyrrolidone, and optionally other pharmaceutical excipients, the formulation being in the form of a coated or uncoated tablet or capsule.

Abstract: An improved flatbed scanner comprises a frame transparent scanner and a cradle having a lid. The frame transparent scanner is a stand-alone portable scanner that can scan both transparent and opaque scanning objects. When the frame transparent scanner is rested in the cradle, a flatbed scanner, appearing as a regular flatbed scanner, is structured. The operations are no different from that of the regular flatbed scanner. One of the advantages and benefits of the disclosed flatbed scanner is that a user no longer has to have two scanners, typically, one for mobile applications and one for stationary applications. With the current disclosed flatbed scanner, the user can take the frame transparent scanner off the cradle for the mobile applications and rest the frame transparent scanner in the cradle for office uses.
