摘要： A method and apparatus to provide accurate and automated timing of firmware routines, such as initialization tasks at boot time, is provided. Since each task sends a progress indicator code to a display buffer when it starts to run, by saving processor time stamps at the time these codes change, it is possible to calculate and store the time duration for each routine. In the case of system initialization, these time durations can be an indication of problems if they are much longer than normal or an indication of excessive, inefficient, or ineffective processing that might be speed up in order to reduce the total boot time.

摘要： A multiple function atmospheric pressure ion source interfaced to a mass spectrometer comprises multiple liquid inlet probes configured such that the sprays from two or more probes intersect in a mixing region. Gas phase sample ions or neutral species generated in the spray of one probe can react with reagent gas ions generated from one or more other probes by such ionization methods as Electrospray, photoionization, corona discharge and glow discharge ionization. Reagent ions may be optimally selected to promote such processes as Atmospheric Pressure Chemical Ionization of neutral sample molecules, or charge reduction or electron transfer dissociation of multiply charged sample ions. Selected neutral reagent species can also be introduced into the mixing region to promote charge reduction of multiply charged sample ions through ion-neutral reactions. Different operating modes can be performed alternately or simultaneously, and can be rapidly turned on and off under manual or software control.

摘要： Atmospheric pressure, intermediate pressure and vacuum laser desorption ionization methods and ion sources are configured to increase ionization efficiency and the efficiency of transmitting ions to a mass to charge analyzer or ion mobility analyzer. An electric field is applied in the region of a sample target to accumulate ions generated from a local ion source on a solid or liquid phase sample prior to applying a laser desorption pulse. The electric field is changed just prior to or during the desorption laser pulse to promote the desorption of charged species and improve the ionization efficiency of desorbed sample species. After a delay, the electric field may be further changed to optimize focusing and transmission of ions into a mass spectrometer or ion mobility analyzer. Charged species may also be added to the region of the laser desorbed sample plume to promote ion-molecule reactions between the added ions and desorbed neutral sample species, increasing desorbed sample ionization efficiency and/or creating desired product ion species. The cycling of electric field changes is repeated in a timed sequence with one or more desorption laser pulse occurring per electric field change cycle. Embodiments of the invention comprise atmospheric pressure, intermediate pressure and vacuum pressure laser desorption ionization source methods and devices for increasing the analytical flexibility and improving the sensitivity of mass spectrometric analysis.

摘要： EEH methods are used during the boot process to actively disable a defective PCI adapter, thereby allowing the system boot to continue without disruption. This allows faulty adapters to be present in the machine without interrupting the boot process. The slots appear to be empty and the devices/adapters residing therein can be actively “hot swapped” out without altering the rest of the machine state.
摘要翻译：在引导过程中使用EEH方法主动禁用有缺陷的PCI适配器，从而允许系统启动继续而不中断。这允许错误的适配器存在于机器中，而不会中断启动过程。插槽看起来是空的，其中驻留在其中的设备/适配器可以在不改变机器状态的其余部分的情况下主动“热插拔”。

摘要： Improvements have been made for selective collecting, focusing, and directing of ions and/or charged particles generated at atmospheric or near atmospheric pressure sources, such as but not limited to, electrospray; atmospheric pressure discharge ionization, chemical ionization, photoionization, and matrix assisted laser desorption ionization; and inductively coupled plasma ionization. A multiple-aperture laminated structure is place at the interface of two pressure regions. Electric fields geometries and strengths across the laminated structure and diameters of the apertures; all of which act to optimize the transfer of the ions from the higher pressure region into the lower pressure region while reducing the gas-load on the lower pressure region. Embodiments of this invention are methods and devices for improving sensitivity of mass spectrometry when coupled to atmospheric, near atmospheric, or higher pressure ionization sources by reducing the gas-load on the vacuum system.
