Title: Synthesis of 4-ketocyclopentene and cyclopentadiene compounds
Inventor: SHANKAR RAVI B
IPC: C07C49/683
Filed: 1999-11-19
Abstract: A process for forming 4-ketocyclopentene and substituted 4-ketocyclopentene compounds starting from the corresponding 1-carbohydroxarbyloxy-2-keto-4- hydroxy-5-cyclopentene by reduction followed by decarboxylation. The ketone may thereafter be converted to a cyclopentadiene compound by reducing the ketone to form an alcohol, replacing the hydroxyl functionality of the alcoh ol under substitution conditions with a leaving group, and deprotonating the resulting product under base induced elimination conditions to form the cyclopentadiene compound. Alternatively functionalized cyclopentadienyl compounds can be produced without isolation of an unsubstituted cyclopentadienyl compound by combining the elimination and deprotonation ste ps with a replacement step in a single unit operation.

Title: Rapid determination of present and potential battery capacity
Inventor: PODRAZHANSKY YURY
IPC: G01R31/367
Filed: 2000-01-31
Abstract: Rapid determination of the condition or charge parameters of a battery, such  as the present charge of the battery and the maximum charge capacity of the battery. A plurality of discharge pulses (210) and a plurality of rest perio ds (220) are applied to the battery. The battery voltage is then measured to provide voltages (225) during the rest periods, and/or voltages (230) during  the discharge pulses. The voltage difference among selected one of the voltages are used to provide a difference voltage DELTA-L. The difference voltage DELTA-L is then used to determine a charge parameter of the battery,  such as the maximum charge capacity or condition of the battery and the present charge in the battery. This information is then displayed to a user so that the user will know the present capacity and the present charge of the battery and can make an informed decision as to whether the battery is adequate for the project that the user has in mind, or to a subsequent process, such as a charging process.

Title: Prefabricated biological purification apparatus
Inventor: BRUSO LUIGI
IPC: C02F3/02
Filed: 1999-11-19
Abstract: The invention relates to a prefabricated biological purification apparatus for the purification of domestic sewage and forms part of the technological field of civil engineering. The apparatus of the invention is very versatile due to the fact that it can be used in different types of constructions such as individual homes, condominiums, buildings, towns, etc. including a unitary facility or multiple facilities depending on requirements. The prefabricated biological purification apparatus comprises two basic units consisting of two containers whose size varies depending on the type and equipped with all modular elements, bottom, walls and lids, in addition to all complementary internal elements. The shape of all components makes them easy to handle, transport and assemble and no special machinery or skilled labor are required. The apparatus operates as follows: in the first unit, which is a prefabricated biological purifier, as shown in Patent Publication EP  0.878.444, that includes internal and external variations for optimized operation, the first and most important purification phase is effected, wherein the sewage is treated in three successive phases involving aerobic and anaerobic fermentation and decanting, it is possible to internally recirculate the sludges and the effluent of the purifier enters the second unit where it is evenly distributed by means of a liquid distributor. Purification is completed in said unit by oxidation of contaminating matters as a result of a bacterial film that covers the filling material. A successive aerobic and partly anaerobic fermentation phase is carried out in said unit. The effluent of the apparatus can be emptied into a receptacle involving no further treatment. As the apparatus does not produce any sludges, no regular maintenance or cleaning is required. The apparatus involves no operating costs as no machinery is needed for internal operation, and the apparatus has no environmental impact since the entire facility is built underground.

Abstract: There are provided an apparatus and method for retransmitting data according to a radio link protocol in a mobile communication system. In the method of requesting frame retransmission, a receiver stores the sequence numbers of a plurality of RLP (Radio Link Protocol) frames that are not received from a transmitter and transmits a retransmission request frame including fields that indicate the sequence numbers. Then, the transmitter sequentially transmits the requested RLP frames in the order of the sequence numbers to the receiver. The receiver compares the stored sequence numbers with the sequence numbers of received RLP  frames and if it receiver fails to receive one of the requested RLP frames, the receiver requests retransmission of the lost RLP frame upon receipt of an RLP frame of a higher sequence number than the sequence number of the lost RLP frame.

Title: Hdtv remote computing user interface
Inventor: PICARD WAYNE F J
IPC: H04N7/173
Filed: 2002-04-09
Abstract: A High Definition Television Set (HDTV) contains an MPEG-2 video and audio decompression codec which can be used to decode suitably encoded computing images from a remote server (a computer servicing a large number of users). While the video quality is acceptable due to the high definition resolution, there is a delay associated with the compression and decompression of the video as well as a latency due to the multi-user nature of the server platform. This video delay makes the normal keyboard mouse interaction with the program unusable. I am proposing a new user interface using a local mouse-keyboard with limited local processing to allow the standard application programs "cut and paste" feature to be modified at the system level to achieve a new and versatile user interface without modifying the applications programs in any way. Blocks of data cut from a document would be seat to the HDTV for editing in a local buffer prior to being returned to a user defined point in the original document (at the server). The server would process the changes, update the video image which would then be re-compressed prior to being resent to the HDTV set. The video image would be displayed (after decompression) in a window above the "cut and paste" window on the HDTV set.
