Living cellular material is encapsulated or placed in a protective material (cell protector) which is biocompatible, biodegradable and has a three-dimensional form. The three dimensional form is incorporated into a matrix that maybe implanted in vivo, ultimately degrade and thereby by replaced by living cell generated material.

The disclosure provides a tissue removal device including customizable tips. The tissue removal device may include an outer shaft and a threaded shaft. One aspect of disclosure may include a shaft cutting tool that emerges from the end of the outer shaft. Another aspect of the disclosure may include a flexible cutting blade extending from the threaded shaft. Threaded shaft may be driven by a driving mechanism in order to provide an auger-like suction mechanism to facilitate the transfer of removed tissue to a collection chamber that is coupled to the outer shaft and the threaded shaft.

This invention discloses structures of organic materials-based semiconductor devices and methods for the fabrication of such devices. According to this invention, each of the devices has a first part and a second part. The first part has at least a first organic semiconductor material layer deposited on a first electrode and the second part has at least a second organic semiconductor material layer deposited on a second electrode. Said device is formed by assembling the two individual parts together. Each part maybe fabricated separately and consists of an electrode coated with semiconductor organic materials required by the function of the desired device. A schematic diagram in the FIG. 3 shows a first part (11) consisting of a first substrate (13), a first electrode (14) and at least one layer of organic materials (15); the second part (12) of the device consisting of the second substrate (16), a second electrode (17) with at least a layer of organic materials (18). The organic device (10) is finally obtained by combining the first part (11) with the second part (12) under controlled environment. This is preferably done by aligning the first part (11) onto the second part (12), and then by initiating a cross-link between organic material (15) and organic material (18) via heating, electron beam or light irradiation.

The present invention provides a combination hat and sunglasses / goggles, in which the sunglasses / goggles are pivotally moveable relative to the hat, between a raised, out of the way position to a lowered position with the eyepiece in front of the wearer's eyes, through an elongated aperture in the front brim of the hat. In addition, the sunglasses / goggles can be fully detached and removed from the hat, so that they can be used as regular sunglasses. The combination is easy to assemble and disassemble, and simple and convenient to operate, providing versatility and reduced risk of loss of components of the combination.

An apparatus for controlling airflow in a fiber extrusion process includes a fiber flow region between an inlet through which extruded fibers are received and an outlet through which the extruded fibers are discharged and at least one surface providing a boundary between the fiber flow region and another region, wherein the surface includes apertures permitting air to flow between the fiber flow region and the other region to control airflow at the outlet of the fiber flow region. The apparatus can include a housing which contains at least one chamber, with the surface forming a boundary between the fiber flow region and the chamber, such that the apertures permit air to flow between the fiber flow region and at the chamber. In a spunbond process, the airflow control device receives drawn filaments exiting an aspirator and deposits the filaments onto a web-forming surface with reduced air disturbance.

First and second waveguides which have respective axes thereof arranged parallel to each other are respectively held by dielectric feeders. A projection wall or a thick wall is formed as a correction part on a front surface of a waterproof cover which covers radiation parts of the dielectric feeders. Due to such a constitution, when radio waves transmitted from neighboring first and second satellites are converged by a reflector and are incident on the inside of respective waveguides, it is possible to delay a phase of radio waves which pass the waterproof cover by the correction part (projection wall or thick wall) so that it is possible to adjust such that radiation patterns of radio waves which are incident on the respective waveguides are reflected on a common portion of the reflector whereby the required reflector can be miniaturized.

The 60 GHz channel between the transmitter and receiver can have AWGN characteristics allowing a Time Domain Equalizer (TDE) to be used at the receiver instead of a Frequency Domain Equalizer (FDE). The complexity of performing matrix inversion on a received signal is reduced when directional antennas are used in a 60 GHz system. Incorporating the TDE in place of the FDE saves almost an order of magnitude in power dissipation. For portable units, such a savings is beneficial since the battery life can be extended. The signal quality of wireless channel is based on the characteristics of the received signal to switch the equalization operation from a system performing FDE to TDE and vice versa. The receiver adapts to the received signal to reduce the power dissipation of the system.

The invention discloses a piezoelectric tilting mirror high-voltage driver with the function of compensating the frequency characteristic of an object, comprising a communication interface (1), a digital compensator (2), a digital-to-analog converter (3), and a high-voltage amplifier (4). It is: the communication interface (1) receives the digital control signal sent by the wave front processor, after performing digital compensation in the digital compensator (2), it enters the digital-to-analog converter (3) and converts it into an analog control signal, and then passes through the high-voltage amplifier (4) Amplify the high-voltage power signal to drive the piezoelectric tilting mirror. The digital compensator can real-time compensate the amplitude response at the mechanical resonance frequency of the piezoelectric tilting mirror, which is the driving object of the high-voltage driver, so as to solve the influence of the mechanical resonance peak of the piezoelectric tilting mirror on the adaptive optical servo system. The invention is suitable for high-speed and high-voltage driving of piezoelectric tilting mirrors in the field of adaptive optical systems.
