The present invention is directed to providing systems and methods for remotely monitoring sites to provide real-time information which can readily permit distinguishing false alarms, and which can identify and track the precise location of an alarm. In embodiments, monitoring capabilities such as intrusion / fire detection and tracking capabilities, can be implemented through the use of multistate indicators in an interface which permits information to be transmitted using standard network protocols from a remote site to a monitoring station in near real-time. In embodiments, communications can be handed from the centrally located host monitoring station to a mobile monitoring station (for example, a laptop computer in a responding vehicle, such as a police or fire vehicle). Additional embodiments include the measurement of environmental parameters such as temperature, carbon monoxide and differential air pressure to detect, monitor and manage a fire event. These measurements along with selected controllable output devices deployed in a space, such as sprinkler control valves and individually or zoned sprinkler heads, are used to initiate and control fire suppression technology both locally and remotely. For instance, a system of the present invention may detect a fire and cause a sprinkler system to disburse water in a facility.

A transvascular system (10) for delivering a drug to a tissue region from a blood vessel, such as a coronary vein, includes a catheter (12) having a distal portion (26) with puncturing (14), orientation (16), drug delivery (62), and imaging elements (18). The puncturing element (14) is deployable for penetrating the vessel wall to access the tissue region. The orientation element (16), e.g. a “cage” including a plurality of struts (38) (40) and / or a radiopaque marker, has a predetermined relationship with the puncturing element (14), the imaging element (18) detecting the location of the orientation element (16) with respect to the tissue region to orient the puncturing element. The catheter (12) is percutaneously introducing into the vessel, the puncturing element (14) is oriented towards the tissue region, the puncturing element (14) is deployed to access the tissue region, and the drug is delivered to the tissue region. An ablation device (230) may also be deployed to create a cavity or fluid reservoir in the tissue region for receiving the drug therein, or an indwelling catheter (214) may be advanced into and left in the tissue region.

A digital measuring instrument includes a housing containing a measuring line, a rotatable drum engaging the line whereby movement of the line causes rotation of the drum, a storage spool mounted in the housing for storing the line, a crank assembly for rotating the storage spool for winding the measuring line about the storage spool, and a rotatable disc that rotates simultaneously with the measuring drum. The instrument includes an optical sensor in communication with the rotatable disk for compiling data related to rotation of the disk, and electronic circuitry in communication with the optical sensor for calculating a length of the line drawn from the housing. The housing has a well for receiving the storage spool and a side cover with a slideable lock for covering the well.

A method and apparatus for phase ranging the distance an RFID tag is from an RFID location system antenna along the interrogation signal beam, based upon the phase readings included in data sets obtained from monitoring reply signals corresponding to interrogation signals at multiple frequencies and a common interrogation signal beam direction; by comparison of measured phase and frequency data sets with theoretical phases calculated with respect to the same frequencies over a range of positions corresponding to a beam extent of the interrogation signal.

A method and apparatus for validating a distance output of a phase ranging RFID location system, based upon the phase readings included in data sets obtained from monitoring reply signals corresponding to interrogation signals at multiple frequencies and a common interrogation signal beam direction; by comparison of measured phase and frequency data sets with theoretical phases calculated with respect to the same frequencies over a range of positions corresponding to a beam extent of the interrogation signal. The distance output validated by comparison with theoretical threshold data processed to generate an extreme values distribution from which a cumulative distribution function is extracted and against which a confidence level is applied.

An apparatus for correcting a bar width comprises a detecting section calculating a reference bar width serving as a reference of bar widths, a first calculation section calculating an average value of a plurality of reference bar widths, a second calculation section calculating an error value between a bar width of a bar to be corrected and the reference bar width calculated by the detecting section, and a correcting section correcting the bar width of the bar to be corrected by using the calculated average value when the calculated error value is not less than a predetermined value.

Systems and methods for detection of the directivity of trajectories of charged drops issuing from a jet are disclosed. According to one aspect, an electrostatic sensor is disclosed which includes a flat functional surface. The electrostatic sensor is configured to function in a non-differential manner and has a geometric shape and arrangement that are substantially aligned relative to a nominal trajectory of drops. A trajectory of drops can be followed at the same time in a plane parallel to the flat surface of the sensor and in a plane perpendicular to the flat surface of the sensor. As a result, it can be verified whether a drop is present or remains in a predefined monitoring zone. According to another aspect, a method of controlling trajectories of drops in a print head having a continuous deflected jet, and a method of monitoring the effective recovery by the gutter of drops not intended for printing are disclosed.

For producing a directional layer for instance with constant nominal directionality, such as a low-retentivity layer with a preferred direction of magnetization or a support layer for such a layer by cathode sputtering on a substrate surface (4), the coating process takes place in a manner whereby particles emanating from a target surface (6) impinge predominantly from directions whose projections onto the substrate surface (4) lies within a preferred angular range surrounding the nominal direction. This is achieved for instance by positioning a collimator (8), encompassing plates (9) that extend at a normal angle to the substrate surface (4) parallel to the nominal direction in front of the substrate surface (4), but in lieu of or in addition to such positioning the location or movement of the substrate surface (4) relative to the target surface (6) can also be suitably adjusted or controlled.

A Method and System for Collecting and Surveying Radio Communications From a Specific Protected Area of Operations in or Around a Compound. It is an object of the present invention to provide just such a method to automatically detect communications signals in near real time, from any selectable sub-area of a compound. Such a system would greatly enhance the operational capabilities of the twenty-first century organization by providing a real-time capability to secure radio communications in and around a compound. The system has all the abilities of the system described in the '976 application, but is further able to automatically detect the direction of the incoming signals (relative to two or more collector subsystems in communication with each other), and thereafter to add that information to the surveillance decision logic such that the actual geographical location, as adjusted by the calibration information for the particular compound surveillance decision logic. Secondly, the system has the capability of being calibrated such that the particular RF environment of the compound in question is uniquely mapped. The calibration tables maintained by each network-attached directional collection node of the system invention in order to provide a more robust and accurate signal geo-location system. Thirdly, the system is able to automatically pinpoint the geographic area of the source of the incoming signals and add that information to the monitoring decision logic. Finally, the system provides a user interface to operators so they can easily select areas to monitor, and easily calibrate the system for maximum precision.
