摘要： Reconfigurable antennas in an ad-hoc network are provided where all nodes employ MIMO/SIMO/MISO communication techniques. Three types of reconfigurable antennas: Reconfigurable Printed Dipole Array (RPDA), Reconfigurable Circular Patch Antenna (RCPA) and Two-Port Reconfigurable CRLH Leaky Wave Antennas are used. The RPDA, RCPA and the CRLH Leaky Wave antennas have a different number of configurations as well as different degrees of pattern diversity between possible configurations. To effectively use these antennas in a network, the performance of centralized and decentralized antenna configuration selection schemes are quantified for reconfiguration at one or both link ends. The sum capacity of the network is used as a metric to quantify the performance of these antennas in measured and simulated network channels.

摘要： A method allows reconfigurable multi-element antennas to select the antenna configuration in MIMO, SIMO and MISO communication system. This selection scheme uses spatial correlation, channel reciprocal condition number, delay spread and average Signal to Noise Ratio (SNR) information to select the antenna radiation pattern at the receiver. Using this approach, it is possible to achieve capacity gains in a multi-element reconfigurable antenna system without modifying the data frame of a conventional wireless communication system. The capacity gain achievable with this configuration selection approach is calculated through numerical simulations using reconfigurable circular patch antennas at the receiver of a MIMO system that employs minimum mean square error receivers for channel estimation. Channel capacity and Bit Error Rate (BER) results show the improvement offered relative to a conventional antenna selection technique for reconfigurable MIMO systems.
摘要翻译：一种方法允许可重配置的多元天线在MIMO，SIMO和MISO通信系统中选择天线配置。该选择方案使用空间相关性，信道倒数条件数，延迟扩展和平均信噪比（SNR）信息来选择接收机处的天线辐射图。使用这种方法，可以在不修改常规无线通信系统的数据帧的情况下实现多元可重构天线系统中的容量增益。使用该配置选择方法可实现的容量增益通过使用在MIMO系统的接收机处使用可重构的圆形贴片天线的数值模拟来计算，该系统使用最小均方误差接收机进行信道估计。信道容量和误码率（BER）结果显示出相对于可重配置MIMO系统的常规天线选择技术的改进。

摘要： Leaky wave antennas that can be reconfigured in pattern and/or polarization by exploiting the characteristic of metamaterial structures loaded with variable capacitor and inductors employ a Composite Right Left Handed (CRLH) unit cell with two independent DC biases used to actively change the group delay of the transmission line and the polarization of the radiated field while preserving good impedance matching. Different degrees of pattern and polarization reconfigurability are achieved by cascading multiple of these unit cells along a straight line, a circular line or a zigzag line while preserving high gain for all the antenna configurations and good impedance matching.

摘要： An antenna system that allows increasing the reading reliability of RFId systems by dynamically changing the shape or the polarization of the electromagnetic field radiated by the RPId reader. The system includes at least one reconfigurable antenna, a variable DC bias unit and a methodology to efficiently use the system in RFId applications. The system allows changing the direction in which the energy is radiated or the polarization of the radiated field in order to "move" the electromagnetic field and to also read RFid tags that receive faint signals with standard RFid systems. Polarization alignment between the reader's antenna and the transponder allows for maximum power transfer, while changing the direction of radiation allows concentrating the electromagnetic field towards the transponder.

摘要： The invention refers to a cap (1) comprising a cavity (4) delimited by a cylindrical side wall (2) and by a discoidal base (3) placed at a first end of the cap. The latter further comprises a circular opening (5) for accessing the aforesaid cavity, obtained at a second end of the cap opposite to the first end of the same. A discoidal dividing wall (6) is housed in the cavity of the cap in an intermediate position between the base and the aforesaid opening. The dividing wall is connected to the side wall along the circular edge thereof so as to delimit, together with the base and a portion of the side wall, a section inside the cap. A tongue (11) protruding outside the cap penetrates the latter through the side wall and is connected to the dividing wall at an end thereof inside the cap. The application to said tongue of a force tending to remove the same from the cap tears the dividing wall thus opening the aforesaid section and allowing a substance enclosed in the latter to come out of the cap.

摘要： A blade (40a; 40b) for alternating electric saws (15) having two shanks (42a,-43a;42b, 43b), respectively one at each end of the blade. The shanks comprise connecting means for fitting the blade onto the saw. If the blade is used to cut objects of a thickness considerably less than the length of its central body (41), the blade becomes worn along an extremely short section of its length. When the teeth (44) of the blade are so worn that they can no longer cut, the blade can be detached from its seat in the saw, reversed and reattached using the shank at its other end to do so. In this way cutting operations can be resumed with the same blade but using those teeth not hitherto involved in cutting.
摘要翻译：用于交替电锯（15）的刀片（40a; 40b），其具有在所述刀片的每一端分别具有两个柄（42a，-43a; 42b，43b）的电锯。柄部包括用于将刀片装配到锯上的连接装置。如果刀片用于切割比其中心体（41）的长度小得多的厚度的物体，刀片将沿其长度极短的部分磨损。当刀片的齿（44）如此磨损使得它们不再能够切割时，刀片可以从其在锯中的座椅上拆下，在另一端使用柄重新连接并重新附接。以这种方式，切割操作可以用相同的刀片恢复，但是使用迄今未涉及切割的那些牙齿。

摘要： The invention concerns a photovoltaic prism obtained by assembling single photovoltaic modules of crystalline silicon joined together by their longer sides, so that the active surface lies inside the prism. The base of the prism, opposite to the aperture for entry of sunlight, is closed by a flat bottom, the colour of which is essentially white, that reflects the light entering the prism towards its internal walls so as to exploit the phenomenon of luminous diffusion. Lateral slits are cut in the lower perimeter to allow rainwater to be drained off. Orientation of the photovoltaic prism is controlled by a sun follower to ensure that the axis of the prism is kept constantly parallel to the sun's rays. Several photovoltaic prisms, preferably hexagonal in shape, can be assembled to form a honeycomb configuration oriented as above by a sin le sun follower.

摘要： A planar reconfigurable antenna that is capable of generating omnidirectional and directional radiation patterns over a wide frequency band or over multiple frequency bands includes a substrate, one or more pairs of conductive elements on at least one side of the substrate, a common RF feed point, and respective switches that selectively connects one or all of the conductive elements to the common RF feed point. An omni-directional radiation pattern is generated when all of the conductive elements are connected to the common RF feed point, while a directional radiation pattern is generated when only a pair of conductive elements on opposite sides of the substrate are connected to the common RF feed point. In the directional radiation mode, the conductive elements that are not connected to the common RF feed point act as a reflector for other conductive elements that are connected to the common RF feed point.
