A radiopaque structure, a stent and a thrombectomy system are disclosed. The radiopaque structure includes: at least one protrusion each for securing, supporting and connecting a radiopaque sleeve (); at least one radiopaque sleeve () disposed over the respective at least one protrusion; and at least one filler () filled in a gap between the radiopaque sleeve () and the protrusion. Compared with the prior art, the radiopaque mechanism can enhance fluoroscopic visibility of radiopaque dots disposed at a distal end of a laser-cut thrombectomy device and solves the problem that not all metal struts in the laser-cut thrombectomy device can be seen under fluoroscopic imaging. The radiopaque structure can be used in any types of stent and is not limited to being used in a thrombectomy device.

Techniques are described herein that are capable of dynamically re-allocating computing resources while maintaining network connection(s). Applications of users are run in a computing unit. Computing resources are allocated among the applications based at least in part on dynamic demands of the applications for the computing resources and resource limits associated with the respective customers. In a first example, the computing resources are dynamically re-allocated among the applications, as a result of changing the resource limit of at least one customer, while maintaining at least one network connection between a client device of each customer and at least one respective application. In a second example, the computing resources are dynamically re-allocated among the applications, as a result of changing the resource limit of at least one customer, while maintaining at least one network connection between an interface and a client device of each customer.

Dynamically re-allocating computing resources while maintaining network connection(s)

This invention proposes a novel charging method for improving the efficiency of charging a super capacitor. The method comprises the steps of: charging the super capacitor with a first current; measuring a voltage of the super capacitor; stopping the supply of the first current when the measured voltage reaches a pre-defined voltage value; monitoring a voltage variation of the super capacitor; charging the super capacitor with a second current when the monitored voltage variation exceeds a pre-defined threshold within a pre-defined period. By using said two-phase charging, especially when using two different charging currents, it is easier to improve the charging efficiency without degrading the charging speed.

Supply circuits for supplying voltage and current signals to light sources () comprise switches () and controllers () to control the switches () for reducing values of frequency components of harmonic content of power spectra of the light sources (). By switching one of the voltage and current signals or by switching signals that result in one of the voltage and current signals, the other one of the voltage and current signals can be adjusted. The power spectrum of the light source () may be a function of the voltage and current signals. By adjusting one of them, the power spectrum can be adjusted such that values of frequency components of the harmonic content of the power spectrum are reduced. As a result, visible flicker is reduced in the light originating from the light source () without the use of energy storage capacitors for reducing this visible flicker.
