Abstract: A folded EBG structure has a plurality of cells arranged in a two-dimensional array. Each of the cells has an electrically conductive patch and an electrically conductive via coupled between the patch and a ground plane. In one dimension of the folded EBG structure, at least one patch in that dimension is folded into three sections located in different planes. In general, both ends of the folded EBS structure have folded patches. Via walls having electrically conductive vias are provided on both ends of a folded EBG structure for connecting the cell vias to the ground plane. The distance between each via wall and the folded EBGs is substantially equal to the length of the vias connected to patches.

Abstract: The invention relates to a method for optical inspection of the hirsuteness of a surface. The method comprises directing a light beam (B) to the surface (2) of a wooden piece (1) under study in a direction (D), which deviates from the normal to the surface. The surface is imaged with a camera (8) having an image plane (9) formed by several optoelectronic light-sensitive pixels by imaging at predetermined intervals the surface of the wooden piece moving relative to the camera, each image being in the form of electronic image data. The image data of two consecutive electronic images are subtracted from each other, yielding a set of pixel-related difference data describing the wooden surface under study, and the difference data are used for stating varitions in the surface roughness of the surface under study.

Abstract: Buffering packets of a media stream for transmission from a transmitting device to a receiving device. Media packets are formed from at least one kind of media information in a stream generator; forward error correction data is formed on the basis of the media packets; one or more repair packets are formed on the basis of the forward error correction data; and a transmission schedule is generated for packets to be transmitted. In addition, hypothetical decoding is also performed according to the transmission schedule. The hypothetical decoding comprises buffering the packets to be transmitted according to the transmission schedule to a hypothetical decoding buffer; and controlling the buffer occupancy level of the hypothetical decoding buffer by controlling the operation of the stream generator.

The method comprises receiving at least one television data stream via the User Datagram Protocol (UDP); converting the at least one UDP television data stream into a Transmission Control Protocol (TCP) data stream; and transmitting the TCP data stream via the wireless network connection over a point-to-point link.

Abstract: The invention comprises a method for registering and deregistering user equipment from a communications system and comprises the steps of sending a request to a first node to register or deregister the user equipment from or to the communications system, determining at the first node to determine if the request is a request to register or a request to deregister, and carrying out at one least predetermined operation at a second node only if the request is a request to register.

Abstract: A light guide has a first surface and a second surface with diffractive structures. A slanted facet is provided at one corner of the light guide. The diffractive structures have concentric fringes centered near the slanted facet. Fringes are arranged such that a light beam directed from the first surface at a location P toward the second surface is diffracted by the fringes only if the beam encounters the diffractive structures at a certain direction. The diffracted beam is guided and exits through the slanted surface at an exiting angle, which is correlated to the location P. If the light guide is illuminated in such a way that when an object is present at the first surface, it changes the light intensity of the exiting light beam. By detecting the exiting angle and the change of light intensity, the location of the object can be determined.

Abstract: An apparatus uses a transducer to produce vibration in the ultrasonic frequency range and in the audible frequency range. A membrane or cantilever structure is coupled to the transducer to produce acoustic waves. When the vibration is in the audible frequency range, the membrane structure works like a conventional loudspeaker. When the vibration is in the ultrasonic frequency range, the ultrasonic signal is modulated by audio signal for creating better directivity. The acoustic waves in the ultrasonic frequency range can reproduce directional audible sound due to the nonlinear interaction of ultrasonic waves in air.

Abstract: The present invention is directed to a wire fitting that may be used to pass a wire, cable or other conductor through a surface in order to produce a substantially secure and water tight connection between the wire fitting, the wire and the surface. The wire fitting may include a cap unit that is configured to be removably affixed to a base unit. The cap unit and the base unit may include corresponding threads to allow the cap unit to be screwed onto the base unit. A compressible plug may be placed between the cap unit and base unit in an opening at an end of the base unit. A washer with a set of ridges may also be placed between the cap unit and the base unit on the compressible plug to facilitate compression of the compressible plug and secure the cap unit into place.

Abstract: The invention relates to a method as well as a system, a device, an encoder and a decoder, and a computer software product for image processing by the method. In the invention, the number of bits is limited in the bit string of a pixel to be processed, wherein the pixel is encoded with the limited number of bits. A prediction value corresponding to said pixel is searched for. If it is found, the difference between the pixel and the prediction value is determined, to select the method for encoding the bit string of said pixel. Also, a code word is encoded in the bit string, to indicate the selected encoding method. If the prediction value is missing, the number of bits in said pixel is limited by quantizing. By means of the invention, a fixed number of bits is obtained for all encoded pixels in an image.
