Abstract:
A plurality of sensors are used to sense disturbances in a data storage system. An adaptive gain component is associated with each of the sensors and provides a gain for each of the sensor signals. The gain of each sensor signal is adapted, individually, based on a correlation of each given sensor signal to the position error signal. This adaptation produces a position correction signal. The position correction signal is applied to a position signal that is used to position the reading and writing components and the storage medium relative to one another. This compensates for both rotary and linear vibration disturbances at the same time.
Abstract:
Medical assemblies with a releasable connection and methods of constructing such medical assemblies are disclosed. The medical assemblies generally comprise a stent, a catheter assembly having catheter body a balloon, and a releasable connection between the stent and the catheter assembly that releases the stent from the catheter assembly in response to enlargement of the balloon or when the balloon has been enlarged to an expanded configuration.
Abstract:
A photonic millimeter-wave generator capable of combining wired and wireless communication facilities to further elongate the transmission distance comprises a laser generator for generating a first optical signal; an optical frequency comb generator coupled with the laser generator; and a pulse shaper coupled with the optical frequency comb generator. The optical frequency comb generator receives the first optical signal generated by the laser generator and outputs a second optical signal. The second optical signal contains multiple frequency components and is sent to the pulse shaper. The pulse shaper adjusts the amplitude and phase of the second optical signal and then outputs the signal as a third optical signal.
Abstract:
A heat dissipation module includes a heat-absorbing unit, a first heat pipe, a second heat pipe, and a heat-dissipating unit. The heat-absorbing unit is adapted to contact the heat source thermally. The first heat pipe has a first heat-absorbing section being connected to the heat-absorbing unit and a first heat-dissipating section. The second heat pipe has a second heat-absorbing section being connected to the heat-absorbing unit and a second heat-dissipating section. The heat-dissipating unit includes a first fin assembly and a second fin assembly. The first heat-dissipating section is connected to the first fin assembly along a first extending direction, the second heat-dissipating section is connected to the second fin assembly along a second extending direction, the first extending direction and second extending direction are oblique to each other, and a part of the first fin assembly and a part of the second fin assembly are inset to each other.

Abstract:
Stents fabricated from hydrolytically degradable polymers with accelerated degradation rates and methods of fabricating stents with accelerated degradation rates are disclosed.
Abstract:
A signal sending device, a signal receiving device, and a signal sending and receiving system and method are presented. The devices and system combine a plurality of sense data into a data packet to transmit the data packet. Through the method, the data packet is processed, received, and sent under a transmission mechanism based on independent data packets. Therefore, the plurality of sense data and overhead data are combined into a data packet, and thus the redundant overhead data is reduced, so as to reduce the time spent on sending actual data to a transmission channel, thus improving the efficiency of data exchange and saving electrical energy.
Abstract:
A method of treating a bodily lumen with a stent including disposing a stent within a bodily lumen in which the stent has a plurality of deformable struts that are substantially circumferentially aligned is described. The deformable struts are configured to selectively deform in a circumferential direction in localized regions in the struts upon application of an outward radial force. The stent is expanded by applying the outward radial force which causes selective deformation of the deformable struts in a localized region in the struts.
