A method and system to protect users against potentially fraudulent activities associated with spoof web sites are described. According to one aspect of the present invention, the URL of a document downloaded via a web browser client is compared to the URLs in a list of URLs for known spoof sites. If the URL for the downloaded document is found in the list of URLs for known spoof sites, a security indicator is displayed to the user to indicate to the user that the downloaded document is associated with a known spoof site. According to another aspect of the invention, a security server maintains a master black list and periodically communicates updates of the master black list to the local list of a client security application.

A method and system for detecting effort events is disclosed. Effort may be determined through feature analysis of the signal as transformed by a continuous wavelet transform, which may be compared against a reference effort measure to trigger an effort event flag that signals the onset and/or severity of an effort event. For example, a respiratory effort measure may be determined based at least in part on a wavelet transform of a photoplethysmograph (PP G) signal and features of the transformed signal. A respiratory reference effort measure may be based at least in part on past values of the respiratory effort measure, and a threshold test may be used to trigger an effort event flag, which may indicate a marked change in respiratory effort exerted by a patient.

The apparatus includes an electrical energy storage capacitor bank capable of quickly releasing stored energy. The apparatus includes a high speed, high current electronic switch capable of quickly transferring the stored energy from the capacitor bank to the coil thereby producing in the coil a short duration, single polarity magnetic field pulse. The apparatus includes a sample and hold circuit capable of acquiring magnetic field sensor data during periods when the pulsed magnetic field is not present. The apparatus includes a microprocessor controller to control timing and sequence of the magnetic pulse generation and the sensor data sample and hold process. The apparatus may be for portal handheld or head mounted applications.

The present invention is a high-sensitivity insulation resistance detection method and circuit for an ungrounded DC power supply systems. When the ratio of the voltage of the positive bus to that of the negative bus exceeds a preset range, the DC current is injected into the ungrounded DC power supply systems. DC power supply systems have essentially some grounded stray and external capacitors, so some of the injected DC current will flow into the grounded capacitor, increasing the voltage of the fault bus and the leakage current. The proposed method increases the leakage current by the injection of DC current, so the current sensor can detect the leakage current from which the insulation resistance can be calculated. The DC current injection method can significantly improve the detection of ground insulation faults in ungrounded DC power supply systems.

A system enables consumers to perform self-checkout and self-check-in of rental articles, especially rental video media. The system includes a scanner, a payment module, and an article transporter. The article transporter carries scanned articles having an attached, permanent EAS tag outside of an EAS tag interrogating zone. The self-checkout station of the present invention permits a consumer to identify his or her account and scan various video media for rental. The consumer may provide payment through the payment module and, once payment is accepted, the article transporter may be activated to carry the rented articles outside of an EAS tag interrogation zone adjacent to the self-checkout station.

A portable, closed-loop system of capture, analysis, and feedback uses a headset containing a small unobtrusive camera and a control computer that communicates wirelessly with a wireless network and/or remote platform. The headset may also contain user controls, an audio feedback component, a battery, interconnection circuitry, cables, and connections for an intraoral device. The camera component of the headset captures images during an activity to be analyzed, such as walking or viewing a room, and sends data (e.g., visual data) to the controller. The controller transmits the data to a database on the remote platform that includes software that instantly analyzes the image information represented in the data, then provides immediate feedback to the headset. The controller may independently process the data.

The technical effect is by tracking the timing delays between nodes as observed by an individual node, and collecting such information together for subsequent processing, nodes may receive and/or construct an entire physical network topology using an algorithm accordingly.

To generate a tomosynthetic 3D x-ray image composed of a number of slice images, a tomosynthetic 3D intermediate image composed of a number of slice images is reconstructed from 2D projection images that have not been noise-filtered. The microcalcium regions contained in these slice images are segmented, and one or more subject slice images relevant to these microcalcium voxels are determined for each microcalcium region. The microcalcium voxels belonging to the segmented microcalcium region in this subject slice image or in these subject slice images are projected forwards in the 2D projection images, and the microcalcium pixels associated with these microcalcium voxels are marked in the 2D projection images. Noise-filtered 2D projection images are subsequently generated by subjecting the microcalcium pixels of the 2D projection images to no noise filtering or a noise filtering that leads to a noise reduction reduced relative to the remaining image regions. The tomosynthetic 3D x-ray image is then calculated from the 2D projection images that have been noise-filtered in this manner.

A monitoring device (7) operates on a pressure signal from a blood processing apparatus, e.g. a dialysis machine, which has an extracorporeal blood circuit connected to a vascular system of a subject for pumping blood through a dialyzer, and a treatment fluid supply system for pumping a treatment fluid through the dialyzer. The monitoring device (7) has a first input block (50) for obtaining a first pressure signal (y) from a first pressure sensor (6a) in the extracorporeal blood circuit, and a second input block (51) for obtaining a second pressure signal (w) from a second pressure sensor (6b) in the treatment fluid supply system. An emulation block (56) generates, as a function of the second pressure signal (w), an emulated first pressure signal (y) which emulates a concurrent signal response of the first pressure sensor (6a), and a filtering block (53) generates a filtered signal (y) as a function of the first pressure signal (y) and the emulated first pressure signal (y), so as to suppress, in the filtered signal (}y) compared to the first pressure signal (y), signal interferences originating from the treatment fluid supply system (1b). A pulse detection block (54) processes the filtered signal (y_f) for detection of subject pulses originating from the subject.

A mail doubles detection and correction system for a mail processing system with a feeder includes a mail support configured to support at least two mail pieces in a detection space downstream of the feeder, a pair of vacuum belt assemblies disposed on opposite sides of the detection space, and one or more sensors positioned about the detection space to detect a position of one or more mail pieces in the detection space. Each vacuum belt assembly includes a vacuum port facing the detection space and a perforated belt movable across the vacuum port in a mail transport direction. The system detects a mail double when the sensors indicate that more than one mail piece is disposed in the detection space and corrects the situation by moving one of the belts and holding the other belt stationary to advance only one of the mail pieces, and subsequently moving both of the belts to advance the remaining mail piece. The system detects a normal feed when the sensors indicate only one mail piece in the detection space, in which case both of the belts are moved to advance the mail piece. The system can also be configured to automatically adjust a width of the detection space to accommodate mail pieces having a range of widths.
