Title: Laser-induced differential normalized fluorescence method for cancer diagnosis
Inventor: VO-DINH TUAN
IPC: A61B1/00
Filed: 1995-09-29
Granted: 1999-10-14
Abstract: An apparatus and method for cancer diagnosis are disclosed. The diagnostic method includes the steps of irradiating a tissue sample with monochromatic excitation light, producing a laser-induced fluorescence spectrum from emission radiation generated by interaction of the excitation light with the tissue sample, and dividing the intensity at each wavelength of the laser-induced fluorescence spectrum by the integrated area under the laser-induced fluorescence spectrum to produce a normalized spectrum. A mathematical difference between the normalized spectrum and an average value of a reference set of normalized spectra which correspond to normal tissues is calculated, which provides for amplifying small changes in weak signals from malignant tissues for improved analysis. The calculated differential normalized spectrum is correlated to a specific condition of a tissue sample.

Title: Synchronised electronic identification system
Inventor: MARSH MICHAEL JOHN CAMILLE
IPC: H04B1/59
Filed: 1993-08-26
Granted: 1995-01-19
Abstract: The invention relates to an identification system comprising an interrogator and a plurality of transponders. The interrogator includes transmitter means (30) for transmitting an interrogation signal to the transponder, receiver means (10) for receiving a response signal from the transponder, and processor means (18) for identifying the transponder from data in the response signal. Clock extraction means (12, 20, 22, 24, 26) are further provided for extracting a transponder clock signal from the response signal which is used to synchronise the modification of the interrogation signal with the response signal from the transponder. Each transponder comprises receiver means (110, 116) for receiving the interrogation signal, a transponder clock generator (114), a code generator (112), transmitter means (110), and a modulator (118) connected to the code generator, so that on receipt of the interrogation signal the transponder transmits a response signal containing data which identifies the transponder. The interrogator is adapted to detect successful reception of a response signal from any transponder, to derive a synchronisation signal from the response signal of that transponder, and to modify the interrogation signal synchronously with the response signal to indicate successful reception of the response signal. Each transponder further includes means (116) responsive to a respective modification of the interrogation signal to cease transmission of its response signal. <IMAGE>

Title: Sorbinil and methylsorbinil
Inventor: URBAN FRANK JOHN
IPC: C07D311/58
Filed: 1985-08-19
Granted: 1986-11-20
Abstract: An improved process for preparing (4S)-6-fluoro-spiro-[chroman-4,4 min -imidazolidine]-2 min ,5 min -dione (sorbinil) or its (2R)-methyl derivative (2-methylsorbinil) is disclosed herein, starting from p-fluorophenol in each instance. The final products obtained have known pharmaceutical value as agents for the control of certain chronic diabetic complications. Key steps concerned with the process involve converting p-fluorophenol into the appropriate  beta -(4-fluorophenoxy)-alkane halide, followed by amidoalkylation with N-benzoyl or N-(lower alkanoyl)- alpha -hydroxyglycine to form an intermediate 2-amidoalkylated derivative thereof, and then dehydration and spiroalkylation of said intermediate by treatment with a dehydrating agent and a base to yield a spiroalkylated azlactone compound. The latter compound is then subsequently converted to the known 4-amino-6-fluorochroman-4-carboxylic acid or the novel (2R-methyl derivative thereof, both in the form of their hydrohalide acid addition salts, by employing acid hydrolysis and the intermediate spiro-amino acid hydrohalide salt is thereafter converted to the corresponding methyl or ethyl ester and resolved with  alpha -chymotrypsin to afford the desired (S)-methyl or (S)-ethyl ester. Treatment of either of these latter two esters with an alkali metal cyanate in an acid medium then effects conversion of same to the desired spiro-hydantoin ring compound. Alternatively, the spiro-amino acid hydrohalide salt can also be converted to the desired spiro-hydantoin ring compound in a known manner, involving a sequence of three reaction steps. The spiroalkylated azlactone compound of the instant invention, as well as the methyl and ethyl esters mentioned above, are themselves novel compounds and are valuable as synthetic intermediates in the process of this invention.

Data is stored in the host computer in the form of a series of search terms arranged in a predetermined logical order, and each stored search term is stored with associated data to which users require access. Data retrieval requests are entered by users in the form of search terms corresponding in logical structure to the search terms stored in the host computer. The host computer memory is partitioned into a series of blocks in each of which is stored both search terms falling within a respective predetermined range of the logical order and the data associated with these search terms. Each user terminal has a memory in which is stored an index that cross references the memory address of each block in the host memory with the range of search terms stored within that block. Each user terminal responds to entry of a search term by identifying from the index the memory address of the block storing the range of search terms including the entered search term, and transmitting the identified memory address to the host. The host computer responds by transmitting the content of the block identified by a received memory address to the user terminal from which the received memory address was transmitted. Each user terminal displays data transmitted to it from the host to enable the terminal user to select the data of interest from the received block contents.
