  • Publication number: 20090319761
    Abstract: Restricting execution by a computing device of instructions within an application program. The application program is modified such that execution of the selected instructions is dependent upon a corresponding expected state of one or more hardware components in the computing device. In an embodiment, the application program is modified to place the hardware components in the expected states prior to execution of the corresponding selected instructions. Creating the dependency on the hardware components prevents the unintended or malicious execution of the selected instructions.

  • Publication number: 20090278036
    Abstract: An ion mobility analyzer includes at least one of a “differential mobility analyzer”, an “ion mobility spectrometer” and a “differential mobility spectrometer”, to which charged molecules of interest are fed. Ions are fed to the ion mobility analyzer from a “droplet pickup ion source” including an electrospray ion source at a capillary end, from which charged droplets formed from a solvent mixture having substantially none of the molecules of interest emerge. The charged droplets are pulled by an electric field into a “pickup region” filled with a buffer gas at a pressure or a region close to the surface of a sample, where the charged droplets incorporate the molecules of interest and transfer the charge of the charged droplets to the molecules of interest, when the liquid in the charged droplets has evaporated in a heated desolvation region that is separate or integral with respect to the “pickup region”.

  • Publication number: 20080315087
    Abstract: A method for differential mobility separation of ions using digital-drive based high voltage fast switching electronics. The digital waveform delivered to the spectrometer is characterized by at least two substantially rectangular pulses of different amplitude and polarity. The control circuitry allows for waveform frequency, duty cycle and pulse amplitudes to be varied independently. Balanced as well as unbalanced asymmetric waveforms can be designed for optimum differential mobility separation of ions. The digital drive is designed for differential mobility spectrometers including parallel plate and segmented plate multipoles of planar symmetry, as well as multipoles of cylindrical symmetry, which may optionally be arranged in series. The use of the digital drive establishes alternating electric fields during which the displacement as a result of ion oscillation is determined by mobility coefficients.

  • Publication number: 20080229115
    Abstract: In an example embodiment, executable files are individually encrypted utilizing a symmetric cryptographic key. For each user to be given access to the obfuscated file, the symmetric cryptographic key is encrypted utilizing a public key of a respective public/private key pair. A different public key/private key pair is utilized for each user. Obfuscated files are formed comprising the encrypted executable files and a respective encrypted symmetric cryptographic key. The private keys of the public/private key pairs are stored on respective smart cards. The smart cards are distributed to the users. When a user wants to invoke the functionality of an obfuscated file, the user provides the private key via his/her smart card. The private key is retrieved and is utilized to decrypt the appropriate portion of the obfuscated file. The symmetric cryptographic key obtained therefrom is utilized to decrypt the encrypted executable file.

  • Patent number: 5644128
    Abstract: A position sensitive fast timing detector for determining time-of-flight mass analysis and position of atomic particles includes a channel plate assembly for detecting the impact of one or more atomic particles a transforming them into one or more electron clouds. The electron cloud then passes through an electron detector which includes a meandric delay line located in front of a back plate. A second meandric delay line may also be utilized, wherein the second delay line is orthogonal with the first delay line. A grid may be placed between the first and second meandric delay lines to reduce cross-talk.

  • Patent number: 5233189
    Abstract: A time-of-flight mass spectrometer is disclosed that can be used as the second stage of a tandem mass spectrometer, a so called MS-MS system, for the mass analysis of molecule fragment ions. In this system it is foreseen that the precursor-molecule ion of a particular mass is fractionated in a dissociation medium where a start-time signal is formed at the time of the fractionation. The flight time in this time-of-flight mass spectrometer--and thus the masses of the molecule-fragment ions--are then determined from the arrival times of the individual fragment ions at some stop detector.

  • Patent number: 5017780
    Abstract: The invention covers novel ion reflectors which are conceived principally for use in time-of-flight mass spectrometry. Caused by special electrodes of conical construction, such ion reflectors also have special ion-optical properties which are made possible through optimum compensation of the spherical and chromatic aberrations both of the ion flight times and of the ion flight paths. The time and place focusing of the ions hereby achieved means for time-of-flight mass spectrometers high mass resolution capability and high transmissions.

  • Patent number: 4904872
    Abstract: In a method for generating extremely short ion pulses having a high intensity and a pulsed ion source to generate extremely short ion pulses having a high intensity, the ions are generated by an electron, laser or particle beam and are stored in a potential well formed by at least three electrodes, at least one of the central electrodes having a more attractive potential for the ions in question than the other electrodes. A single electrical pulse is used for extracting the ions from the potential well. Correspondingly constructed pulsed ion sources are particularly suitable for use in time-of-flight mass spectrometry. The ion storage effect is produced by a number of electrodes which generate a potential well for the ions to be detected. The ion compression is determined by the field strength existing during the ion extraction in the ion source which should be approximately equal in the entire area of acceleration.

  • Patent number: 4445516
    Abstract: A method for digitizing and displaying thermographic records of biological or technical structures which makes it possible to recognize abnormal temperature distributions even if they are very small or the corresponding regions differ only very slightly in their temperature value from the adjacent temperature values. In this method, the temperature values at each image point of a thermogram are digitized and the slope of the local change in temperature, i.e. the temperature gradient, is calculated for each image point on basis of its temperature and the measured temperature values of its neighboring points. For a selected image region the local distribution of the temperature gradients is displayed. Abnormal temperature distributions can be recognized from this display at places where large temperature gradients are present.The method is particularly advantageous for use in the field of medicine and serves there for the detection of carcinomas and particularly breast cancer.

  • Patent number: 4164652
    Abstract: An improved process and an arrangement for the registration of ion-, electron- or light-spectra are described. The spectrum is guided continuously or in very small steps past an N-channel detector. After or during the time in which the spectrum shifts, all N-channels are read out. The N-channel information is added to the information in N corresponding digital or analog storage elements. Simultaneously to the shift of the spectrum past the N-channel detector or, subsequently, the information in the N storage elements are shifted one position. Thus, during the next cycle of detection, read out and addition, the information detected corresponding to a specific part of the spectrum is being added to information obtained in prior cycles from the same part of the spectrum.
