Abstract: A system and method of detecting implant detachment within the body of a patient. The activation of the heater coil causes the degradation, melting or reduction of a component that brings the heater coil into or out of electrical contact with another component, or causes the individual loops of the coil to contact each other, thereby resulting in a notable change in resistance in the circuit supplying the heater coil with electricity.

Abstract: A vaso-occlusive device includes inner, intermediate, and outer elements arranged coaxially. The inner element is a filamentous element, preferably a microcoil. The intermediate element is made of a non-metallic material, preferably an expansile polymer. The outer element is substantially non-expansile and defines at least one gap or opening through which the intermediate element is exposed. In a preferred embodiment, when the intermediate element is expanded, it protrudes through the at least one gap or opening in the outer element and assumes a configuration with an undulating, convexly-curved outer surface defining a chain of arcuate segments, each having a diameter significantly greater than the diameter of the outer element. The expanded configuration of the intermediate element minimizes friction when the device is deployed through a microcatheter, thereby reducing the likelihood of buckling while maintaining excellent flexibility.

The invention also concerns the use thereof in the manufacture of support grids for integrated circuits.

Abstract: A communication system (100) is provided that comprises a Radio Access Network (110) having a Radio Network Controller (RNC) (114) coupled to each of a cellular Node B (112) and a Digital Broadcasting Video-Handhelds (DVB-H) Node B (120). When the communication system delivers low rate Multimedia Broadcast/Multicast Service (MBMS) user information, the user information is conveyed via the cellular Node B and a low data rate channel. When the communication system delivers high rate MBMS user information, the user information is conveyed via the DVB-H Node B and a high data rate channel. Thus the communication system provides high rate MBMS data services without imposing the system capacity constraints resulting from the employment of HSDPA by a cellular Node B.

Abstract: A system is disclosed for creating a media object. The system may include a database for maintaining a first set of information including a plurality of media objects, each of the plurality of media objects having an associated object content, and a second set of information including a plurality of advertisement, each of the plurality of advertisements having an associated advertisement content. The system may also include a media creation server in communication with the database and configured to (1) determine, based on the object content and the advertisement content, if at least one media object is appropriate for inclusion in a new media object including a selected one of the plurality of advertisement objects, and (2) create a new media object including the selected advertisement and the determined appropriate media object.

Abstract: A frequency synthesizer SYNT intended to supply an output signal Sout having an output frequency which depends on the average frequency, referred to as symbol frequency, of an input signal Sin beset with a strong phase noise. This synthesizer SYNT includes: a phase/frequency detector PHD comparing the symbol frequency with a predetermined fraction of the output frequency, and supplying a control signal; a low-pass filter LPF filtering the control signal; and an oscillator VCO supplying a signal Sout with a frequency which is adjusted by the filtered control signal Cs. Reference pulses having the symbol frequency are generated within the synthesizer SYNT by means of pulses from an internal clock, which pulses are validated by active states of the input signal Sin.

Abstract: A digital transmission system including synchronizing circuits for estimating and compensating for errors between a local oscillator signal and an input signal. The synchronizing circuits include a phase/frequency detector and correction circuit for correcting errors in an unlocked mode, and a phase detection and correction circuit for correcting errors in a locked mode. Requests for changing the synchronization circuits from the locked mode to the unlocked mode are implemented by state control circuits only after application of at least one decision condition. The state control circuits may also save and restore specific adjustments responsive to the decision condition.

Abstract: Circuit for multiplying data in accordance with a Booth algorithm, in which the coding of the control signals is adapted to the characteristics of symmetry of a trigonometric function. The values of the function which relate to a single quadrant are stored in a memory and a converter unit makes it possible to utilize the circuit whatever the quadrant. The values of the trigonometric function may be obtained through interpolation. Application to the calculations of Fourier transforms or DCT transforms.

Abstract: Digital transmission system (10) for digitally modulated signals, comprising a receiving device (14) which includes a demodulator (110), processing apparatus (120) and carrier synchronizing apparatus (16) for estimating and compensating for synchronization errors. The synchronizing apparatus includes a first loop (1) for phase/frequency correction and a second loop (2) for phase correction, the operation of these loops being controlled by a mode detector (130) depending on whether the receiving device is seeking to unlock or lock. The second loop (2) transforms a phase error signal into a phase correction signal which is mixed in mixer (246) with the signal coming from the demodulator. Preferably, the signals are modulated via a coded modulation.
