  • Patent number: 7625595
    Abstract: A method of monitoring synthesis of PCMO precursor solutions includes preparing a PCMO precursor solution and withdrawing samples of the precursor solution at intervals during a reaction phase of the PCMO precursor solution synthesis. The samples of the PCMO precursor solution are analyzed by UV spectroscopy to determine UV transmissivity of the samples of the PCMO precursor solution and the samples used to form PCMO thin films. Electrical characteristics of the PCMO thin films formed from the samples are determined to identify PCMO thin films having optimal electrical characteristics. The UV spectral characteristics of the PCMO precursor solutions are correlated with the PCMO thin films having optimal electrical characteristics. The UV spectral characteristics are used to monitor synthesis of future batches of the PCMO precursor solutions, which will result in PCMO thin films having optimal electrical characteristics.

  • Patent number: 7543157
    Abstract: A method for segmentedly encrypting the data in a document print job in a manner which preserves options for post-rendering analysis/processing of selected non-content components, and a print job which comes into existence as a consequence of implementation of this method. The method includes identifying and individuating, within such a job, the content commands as distinguished from the non-content commands, and then, as a consequence of such identifying and individuating, encrypting only data contained within the content commands. In one manner of practicing the invention, all data in the content commands is encrypted. In another manner of such practice, only data which is contained within the content-field portions of the content commands is encrypted. The resulting print job, in one form, is characterized with (a) an encrypted part which includes only data contained within content commands, and (b) a non-encrypted part which includes the balance of data contained within the job.
