摘要:
A system and method for laser source detection. An exemplary embodiment of the system includes a first array of lenses, a second array of opto devices (including light sources and light detectors), and at least one processor. By positioning the array of lenses to determine the lens position at which energy from an incoming laser is greatest on the light detectors, the approximate location of the laser source may be determined. Upon determining the source, responsive action may be taken. If the incoming laser is from a friendly party, a friendly-party notification may be provided. If the incoming laser is from an enemy, reciprocal targeting or false reflections may be employed.

A method and system to detect a position of a member movable along a defined path is described. The system includes a magnetic source, an array of sensors, and an analyzer. The magnetic source radiates a magnetic field and is coupled to a movable member. The array of sensors is fixed relative to the movable member. Each sensor generates an output response value based on an angle of the magnetic field passing through each sensor. The array of sensors produces a plurality of output response values for a first position of the movable member. The analyzer receives the plurality of output response values and calculates a composite output response value to determine the first position of the movable member.

A micro discharge device (MDD) ionizer and a method for fabricating the MDD ionizer are disclosed. The MDD ionizer includes a dielectric barrier having a first open end connected to an electrically conductive capillary tube and a second open end connected to a sample collection capillary tube. A circular high voltage electrode can be positioned around the dielectric barrier in close linear proximity to the conductive capillary tube and sealed by a non-conductive epoxy. A plasma discharge can be formed in a flow path through the dielectric barrier when an AC potential is applied between the high voltage electrode and the electrically conductive capillary tube utilizing an electronic controller. Such a plasma discharge in the flow path of the sample achieves soft ionization of gaseous sample molecules. The high pressure region generally occurs in the plasma region (where the ionization occurs). The ions thus are drawn (i.e., pushed or pulled) toward the high vacuum region located downstream where the detector(s) can be located.

Method and system for controlling cylinder to cylinder variations of undesirable emissions in exhaust gas of engines with exhaust gas recirculation. An engine model is used to predict the intake composition of the next cylinder firing based on the composition of the exhaust, as a function of time and applicable engine conditions. At least one engine parameter is adjusted to compensate for the predicted intake composition in order to minimize cylinder to cylinder variations.

A method, device and computer program for locking applications running on a wireless device for specially marked content is presented wherein the application is marked in a special way to condition the device software to recognize that the application is restricted to specific content. A specific piece of content is created and is marked in a special way so that the device software can match the specific piece of content marking to the application marking. After the application and the specific piece of content are deployed onto the mobile device, the device software recognizes the application is restricted to play specific content when the application requests the specific piece of content and compares the requested specific piece of content marking to the application marking. Application access to the specific piece of content is granted in response to the application and specific piece of content markings matching and denied in response to the application and specific piece of content markings not matching.

A viscosity and corrosivity sensor apparatus includes a substrate upon which one or more electrodes are configured. The electrode(s) are exposed to a liquid, such as automotive oil. An oscillator can be connected to the electrode, wherein the oscillator assists in providing data indicative of the corrosivity and data indicative of the viscosity of the liquid in contact with the electrode(s). A viscosity and corrosivity sensor is therefore provided in the same package.

An acoustic wave sensor system for monitoring the etch rate or etchability of a selective material has an acoustic wave sensing device having a piezoelectric substrate and at least one electrode coupled to the substrate for generating a propagating acoustic wave and for detecting changes in frequency or other propagation characteristics of the acoustic wave. A selective material is disposed on the substrate. Changes in propagation characteristics of the wave caused by etching of the selective material by an etchant can be analyzed to evaluate the etching rate or etchability of the selective material. The sensing system can have a wireless sensing device which device is mountable in an oil filter system for monitoring the corrosion of the engine. The sensing device can be configured as BAW, SH-SAW, SH-APM, FPM devices or other acoustic wave devices.

A lubricity sensor includes a flexural plate wave device and a face shear mode bulk acoustic wave device, which is associated with and located proximate to the flexural plate wave device. The face shear mode bulk acoustic wave device and the flexural plate wave device form a lubricity sensor wherein acoustic wave data produced by the flexural plate device together with the face shear mode bulk acoustic wave device when the lubricity sensor is exposed to a liquid relates directly to a lubricity of the liquid thereby providing lubricity measurement data associated with the liquid. The acoustic wave data can comprises the oscillation gain compensation, the frequency, amplitude and/or phase velocity associated with the flexural plate device and the shear mode bulk acoustic wave device such that the oscillation gain compensation, the frequency, amplitude and/or phase velocity provide an indication of the lubricity of the liquid.
摘要:
A system and method for accessing content on an electronic device in an encrypted mode, a decrypted mode or a default mode. A request is transmitted to an application program interface to permit a requesting program to access at least one file. The request specifically identifies whether the requesting program wishes to access the file in an encrypted mode, a decrypted mode or a default mode. It is determined whether the specific form is supported by the application program interface being used by the system, whether the at least one file is protected; and whether the requesting program is permitted to access the at least one file. If the specific form is supported by the application program interface, if the at least one file is protected, and if the requesting program is permitted to access the at least one file, the at least one file is opened in the specific form for use by the requesting program.
