Patent EP-1127289-B1 (EP)
Inventor: CONNER WILLIAM A
IPC: G02C1/02
Filed: 1999-10-21
Granted: 2005-07-13
Abstract: Attachment of a bridge (18) and temple hinge (32) to the lens (12) of eye glasses. The attachment is accomplished by providing a pair of apertures (30) of a selected configuration in each lens adjacent to the outer and inner surface of the lens, a bushing (24) conforming to the lens apertures with a tapered aperture through the center thereof from front to back and tapering the distal ends of the bridge and temple hinges. This combination when in place in the lenses apertures provides a friction lock between the lens and the bridge and temple hinge. The taper can be in the range of 1 to 45 degrees. In another embodiment the lens can also have a tapered aperture either convergent from the front to the back of the lens or divergent from the front to the back of the lens. Ideally a taper of 4.5 degrees in the bushing is preferable with less taper in the lens apertures when tapered lens apertures are utilized. The taper can take the form of a frusto conic section, a cylinder, a rectangular or triangular in cross section. The distal ends of the bridge and temple hinge can be inserted either from the front of the lens toward the back or from the back toward the front. The distal ends of the temple hinge can be inserted directly into the aperture within the bushing for attachment or can additionally be bent formed to provide a bias between the outer surface of the lens adjacent the aperture for non rotational support. In some applications a notch is provided at the outer lens surface and the bent formed portion of the temple hinge is nested therein for additional mechanical support and to increase the resistance of relative rotation of the bridge or temple hinge.

Title: Plant for the industrial cultivation of microalgae such as Spirulina, Scenedesmus, Chlorella and the like
Inventor: DI GIUSEPPE STEFANORI DAVIDE
Filed: 1992-03-06
Granted: 1997-01-24
Abstract: The plant comprises a plurality of straight transparent containers of circular and/or oval and/or elliptical cross-section in a line to which the culture of microalgae are fed, and vibration-exciting elements located within the said containers. These excitors immersed in the culture generate a series of acoustic waves which are capable of producing adequate agitation for growth of the culture. Their purpose is to obtain greater and more rapid growth of the culture, avoiding the problems of stratification of the culture. In order to obtain this result these vibration-exciters are capable of producing a wave which moves the culture in the most uniform way possible throughout the volume of the container. The plant forms part of the biotechnology sector, for hydroponic and microbiological cultures. The plant has been designed to optimise or replace existing biotechnology for the production of biomass deriving from microbiological cultures. <IMAGE>

IPC: H04J13/00
Filed: 2000-05-12
Abstract: In a method for efficient retransmission of data, symbol accumulation is used to retransmit a packet received in error at a lower energy-per-bit level concurrently in the same frame with a new packet. The destination device receives the data transmission and retransmission, demodulates the signal, and separates the received data into the new and retransmitted packet. The destination device then accumulates the energy of the retransmitted packet with the energy already accumulated for the packet received in error and decodes the accumulated packet. The accumulation of the additional energy provided by the subsequent retransmissions improves the probability of a correct decoding. The throughput rate can be improved since the packet received in error is retransmitted concurrently with the transmission of the new data packet. The capacity is maximized since the retransmission of the packet received in error is at a lower energy level than that of the new packet. <??>The method includes puncturing the code symbols of a data packet for transmission in accordance with a first puncturing pattern. If decoding of the punctured transmitted packet of data is unsuccessful, a negative acknowledgement is received at the source device and the code symbols of the data packet are then punctured in accordance with a second pattern for transmission in response to the receipt of the negative acknowledgement. <IMAGE>
