Title: Transition controlled balanced encoding scheme
Inventor: JEONG DEOG KYOON
IPC: H03M7/00
Filed: 1997-03-25
Abstract: A method and apparatus for producing a transition-controlled.   DC-balanced sequence of characters from an input sequence of data bytes is disclosed herein. The bits in each of the data bytes are selectively complemented in accordance with the number of logical '1' signals in each data byte in order to produce selectively complemented data blocks. A cumulative disparity is then determined between the logical values of different type included within ones of the selectively complemented data blocks previously encoded into characters. In addition, a current disparity in a candidate character associated with a current one of the selectively complemented data blocks being encoded is also determined. The candidate character is assigned to the current one of the selectively complemented data blocks if the current disparity is of a polarity opposite to a first polarity of the cumulative disparity.        Alternately, the complement of the candidate character is assigned to the current one of the selectively complemented data blocks if the current disparity is of the first polarity. In a high-transition mode of operation, the bits within data blocks including fewer than a minimum number of logical '1' signals ate selectively complemented so that each such selectively complemented data block includes in excess of the minimum number of logical transitions. In a low-transition mode of operation, the bits within data blocks having more than a predefined number of logical '1' signals are selectively complemented so that each such selectively complemented data block includes less than the maximum number of logical transitions.

Abstract: The invention relates to pharmaceutical compositions for the treatment of pulmonary arterial hypertension comprising a prostacyclin or a prostacyclin analogue, preferably epoprostenol, and an endothelia receptor antagonist, preferably bosentan. The invention further provides methods for treating a subject suffering from pulmonary arterial hypertension using the compositions of the invention.

Title: Search engine for computer graphic images
Inventor: HOOD DAVID
IPC: G06F17/30
Filed: 2002-12-13
Abstract: A method and system for searching databases having items indexed by multiple keywords that are indicative of the item being indexed for easy searching by having keyword lists that reference lists of items that fall under these specific keywords. These keyword lists reference item lists that indicate which item is under which keyword and how this item can be found in a database.  The keyword lists are advantageously searched by storing them in a word tree where each node in the word tree is an element of a keyword. By traversing the word tree to arrive at a bottom node or at an intermediary node from which bottom nodes derive, partial and full keyword searches are performed. These keyword lists and their corresponding item lists are able to be cached at a user computer from which the user performs his or her search.      Any items that match the search terms entered by the user can then be retrieved from a remote server.

Title: Enhanced online sales risk management system
Inventor: GODFREY JOHN C
IPC: G06Q40/00
Filed: 2001-07-11
Abstract: The present invention provides a method and system to implement risk management of foreign exchange of currency related to on an on line transaction. According to present invention an exchange price and a tolerance parameter can be determined for a foreign currency as the foreign currency relates to a base currency. A computer system can receive a spot price relating to a market price for exchange of a foreign currency and compare the spot price with the tolerance parameter. The system can modify the exchange price if spot price exceeds the tolerance parameter. In addition, the system can receive information including the base currency amount involved in an online transaction and transmit the base currency amount and the foreign currency amount, wherein the foreign currency amount is derived according to the exchange price. If desired, a first tolerance parameter and a second tolerance parameter can be utilized, wherein a rise in the spot price is compared to the first tolerance parameter and a fall in the spot price is compared to the second tolerance parameter. In addition, the magnitude of the first tolerance parameter does not need to be equal to the magnitude of the second tolerance parameter. A rise in the spot price can be compared to the tolerance parameter such that the exchange price is modified if the spot price is higher than the tolerance parameter. Similarly, only a fall of the spot price can be compared to the tolerance parameter. Additionally, a spot price can be determined and compared to the tolerance level at predetermined periods of time. An original tolerance level can be modified to create a new tolerance level, if the spot price exceeds the original tolerance level.
