摘要:
The invention concerns methods for processing a signal emitted by a particle detector. Said methods are characterised in that they consist in: detecting in said signal the portions where the signal is greater than a predetermined value V1, measuring the maximum value Vmax reached by the signal in each of said portions, and associating with each of said portions an analog quantity Q which, at least in a predetermined range of values DELTA V1 of said maximum value Vmax, is an increasing function of (Vmax-V1). The invention is applicable to various devices and appliances implementing said methods.

A wireless (e.g., leadless) marker for localizing the position of a target within a patient. In one embodiment, the marker includes a casing, a resonating circuit, and a ferromagnetic element. The ferromagnetic element can have a volume such that when the marker is in an imaging magnetic field having a field strength of 1.5 T and a gradient of 3 T/m, then the force exerted on the marker by the imaging magnetic field is not greater than gravitational force exerted on the marker. In an alternative embodiment, the ferromagnetic element need not have such a volume, but the marker further includes an imaging element incorporated with the casing and/or the magnetic transponder (e.g., resonating circuit). The imaging element produces a radiographic profile in a radiographic image such that the marker has a radiographic centroid at least approximately coincident with the magnetic centroid of the transponder.

A method for sensing a disturbance in a transmission path of a converging ultrasound energy beam transmitted by a transducer in a docussed lutrasound system comprises transmitting a burst of ultrasound energy from the transducer, detecting whether a reflected portion of the ultrasound energgy burst is received at the tranducer within a certain time period following transmission of the burst, and, if so, analyzing the received reflected portion to determine a characteristic of the disturbance.

The invention relates to an assembly for connecting an rf-SQUID magnetometer to a supraconductive tank circuit on a substrate, in which a resonator and the rf-SQUID form a coplanar structure, the rf-SQUID having a SQUID washer structure. In said assembly, the resonator is configured within the space delimited by the rf-SQUID.

A system for electronic commerce avoids the transmission of credit card numbers across the Internet (6). Internet vendor sites (7, 8) are registered with an ISP (5). Consequently, action URLs from credit card details forms for the vendor sites (7, 8) can be intercepted by the ISP (5). These action URLs are then modified to include a transaction ID code in place of the credit card details and sent to the relevant vendor site (7, 8) with the ISP (5) mimicking the user (1, 2, 3). The ISP (5) may be a financial service provider or have a secure communication link to a financial service provider.

The present invention provides an electro-optical isolation system (10) for coupling an electronic measuring device to a device under test (12) for making accurate measurements of signals within a wide frequency range while the device under test (12) is being subject to high power electrical disturbances (14, 16). The invention provides an increased rejection of high common mode signals and reduction of undesired self-capacitance by implementing a shielded handheld transmitter unit (18) having an integrated measurement probe (24). The transmitter unit (18) converts the sensed signal to an optical signal which is transmitted through an optical medium to a receiver unit (22). Under control of a microprocessor (116), the level of the output signal from the transmitter unit (18) is modulated by the signal received from the sensing probe (24). The microprocessor (116) within the transmitter unit (18) automatically controls the level of optical signal (126) emitted by the optical converter (124), and further calibrates a driver circuit (134) to maintain measurement accuracy. The modulated optical signal (126) emitted by the electro-optical converter (124) is communicated to the receiver unit (22) by an optical fiber medium (20a or 20b).
摘要:
Electronic unit for measuring electric energy supplied by a producer to a user, comprising sensors (of the current and/or voltage and/or power and/or rotational or other type) located directly or indirectly on the power supply line and an electronic unit for processing the signal provided by said sensors, said unit comprising at least one database and at least one programmable microprocessor. According to the invention, the program which runs on said microprocessor is organized as a set of algorithm agents, including at least one "agenda" algorithm agent and at least one "function" algorithm agent (for each of the functions: measurement, processing, communication); said algorithm agents operate independently as concurrent processes; and said algorithm agents interact only by means of remote procedure calls, without sharing data.
