Filed: 1999-02-10
Abstract: Initially, a lower electrode 3 (Fig.4A), an oxide piezoelectric sheet 4 and an electrode layer 5 are laminated over a vibrating plate 2 with an integral chamber plate 1. A photoresist film 6 (Fig.4B) is coated over the upper surface of the electrode layer. Some film is removed (Fig.4C) through baking, exposure to light and rinsing to remove unnecessary portions thereof. The electrode layer is then etched (Fig.4D) at exposed portions, and patterned using the remaining film as a mask, to form upper electrodes of a desired pattern. The remaining film, which is left on the patterned upper electrodes, is completely removed using a rinsing solution (Fig.4E). Another photoresist film (6,Fig.1F) is coated over the entire upper surface of the resulting structure, i.e. the exposed upper surface portions of the oxide piezoelectric sheet 4 and the upper surfaces of the upper electrodes 5. Some film is removed through baking, exposure to light and rinsing to remove unnecessary portions thereof such that remaining portions of the second film (Fig.1G) have a larger area than the upper electrodes associated therewith. The remaining film is hard-baked, and the oxide piezoelectric film is etched (Fig.1H) at exposed portions thereof using the remaining film as a mask to form oxide piezoelectric elements of a predetermined pattern. The second film is then removed to form the microactuator (Fig.1I). Several other methods of forming the microactuator are disclosed (Figs.1A-E,2A&B,3A-D,5A-12D). For example, the chamber plate maybe etched and patterned to form chambers therein following the formation of the oxide piezoelectric elements (Figs.3A-D).

Title: Decoding watermarked data using keys and FFT
Inventor: SEWELL ROGER FANE
IPC: G10L19/018
Filed: 2000-07-27
Abstract: Decoding a stegotext signal (ie watermarked data eg music) generated by modulating the log power spectrogram of a covertext signal (ie. unwatermarked data) with at least one key, the or each key having been added or subtracted in the log domain to the covertext power spectrogram in accordance with the data of the watermark code with which the stegotext was generated, and the modulated power spectrogram having been returned into the original domain of the covertext. The decoder carries out Fast Fourier Transformation 43 and rectangular polar conversion 44 of the stegotext signal so as to transform the stegotext signal into the log power spectrogram domain; subtracts in the log power domain positive and negative multiples of the key or keys from blocks of the log power spectrogram and evaluates the probability of the results of such subtractions representing an unmodified block of covertext in accordance with a predetermined statistical model.
Patent GB-2366479-A (GB)
Title: Downlink data delivery in a cellular communication system,
Inventor: SETTY DAVID
IPC: H04L12/28
Filed: 2000-08-16
Abstract: A cellular communications system comprises a plurality of base stations serving respective system cells, each base station being capable of communicating with a plurality of mobile terminals within its cell and with at least some mobile terminals in adjacent system cells. Where connection of a mobile terminal to one of the base stations demands the downloading of information that, combined with data already being handled by that base station, would place excessive load on the data-handling capability of the base station, the data transmission is shared by that base station and at least one other. By this means, a call requesting the downloading of significant amounts of data, placed by a mobile terminal upon a base station that is already heavily loaded with data transmissions to other mobile terminals, is dealt with in parallel by two or more base stations, so that individual base loading is substantially reduced. It is preferred that the amount of data transmiffed to the mobile terminal by each of the base stations involved takes account of the existing load applied to the individual base stations, so that more lightly-used base stations can be made to bear the brunt of the heavy demand from the new mobile terminal. It is also preferred that the data be co-ordinated by one or more of the base stations in order to ensure its cohesive transmission.

Title: Method for the identification and speciation of bacteria of the burkholderia cepacia complex
Inventor: MAHENTHIRALINGAM ESHWAR
IPC: C12Q1/68
Filed: 1999-09-03
Abstract: Identification and speciation of bacteria of the <I>Burkholderia cepacia</I> complex in a sample can be accomplished by: a) obtaining nucleotide sequence information for the <I>recA</I> gene in bacteria of the <I>Burkholderia cepacia</I> complex found in the sample; and b) comparing the nucleotide sequence information obtained for the <I>recA</I> gene in bacteria of the <I>Burkholderia cepacia</I> complex found in the sample with a standard library of nucleotide sequence information comprising standard nucleotide sequence information for at least three species of bacteria of the <I>Burkholderia cepacia</I> complex. Preferably, the nucleotide sequence information is obtained by evaluation of restriction fragment length polymorphism (RFLP). Other techniques for obtaining sequence information can also be used, including base-by-base determination of the sequence of the region of interest, sequence-specific oligonucleotide hybridization probes, and ligation techniques. Universal primers which can be used for amplification of all known members of the <I>Burkholderia cepacia</I> complex, and genomovar-specific primers which can be used for selective amplification of the <I>recA</I> gene from bacteria of one genomovar provide alternative analytical modalities. Speciation of bacteria of the <I>Burkholderia cepacia</I> complex can be used as a basis for administration of a vaccine specific to the flagellin of the bacteria, since it is shown that this flagellin is conserved across members of genomovar III, subgroup RG-B.

Title: Automatic loading of an inkjet cartridge into an inkjet printer using a shuttle carrier which moves to transfer a loaded cartridge to a printer carriage
Inventor: BELON JUAN B
IPC: B41J2/175
Filed: 2001-04-02
Abstract: A shuttle carrier 110 transfers an ink-jet cartridge 30 between a printer carriage 200 and a shuttle access location on a printer front panel. When a pen load button is pushed, the shuttle moves to an access position. In the access position, the shuttle opens a door 60 and comes beyond a front face (54,Fig.1) of the printer. This allows a user to drop the cartridge(s) into place on the shuttle. Then when the button is pushed again, the shuttle transfers the pens back into the printer, with the door closing, and automatically loads the cartridge(s) into the printer carriage without manual user intervention. The shuttle then moves to a rest position for normal printer operation. If the cartridge load button is pressed again, the shuttle moves back to the carriage and unloads the cartridge(s) automatically. The shuttle again opens the access door and presents the cartridges to the user. The shuttle may include cartridge wipers (320A-320D,Fig.3) and capping structures (342A) mounted for movement with the shuttle, allowing for cartridge service franctions to be performed without the need for an additional service station.
