Patent EP-4284026-A2 (EP)
Inventor: BOEHM JOHANNES
IPC: H04S3/00
Filed: 2013-07-16
Abstract: The invention discloses rendering sound field signals, such as Higher-Order Ambisonics (HOA), for arbitrary loudspeaker setups, where the rendering results in highly improved localization properties and is energy preserving. This is obtained by a new type of decode matrix for sound field data, and a new way to obtain the decode matrix. In a method for rendering an audio sound field representation for arbitrary spatial loudspeaker setups, the decode matrix (D) for the rendering to a given arrangement of target loudspeakers is obtained by steps of obtaining a number (L) of target speakers, their positions ( OL), positions ( OS) of a spherical modeling grid and a HOA order (N), generating (141) a mix matrix (G) from the positions ( OS) of the modeling grid and the positions ( OL) of the speakers, generating (142) a mode matrix (Ψ̃) from the positions ( OS) of the spherical modeling grid and the HOA order, calculating (143) a first decode matrix (D̂) from the mix matrix (G) and the mode matrix (Ψ̃), and smoothing and scaling (144,145) the first decode matrix (D̂) with smoothing and scaling coefficients.

Abstract: Spheroidal polymer beads having a uniform size are prepared by polymerizing uniformly sized monomer droplets formed by the vibratory excitation of a laminar jet of monomeric material flowing in a continuous liquid medium containing a suitable suspending agent. For example, a laminar jet of a monomer mixture comprising a monovinyl aromatic such as styrene, a polyvinyl aromatic such as divinylbenzene and a polymerization initiator are subjected to vibratory excitation and the resulting monomer droplets polymerized to yield copolymer beads having a narrow particle size distribution. These copolymer beads can be employed to prepare ion-exchange resins having superior properties, particularly in continuous ion-exchange operations.

Abstract: images and respectively associated timing marks are arrayed, as phototransparencies, about a disk. The disk is rotated and the timing marks are sensed. Display occurs either in two-dimensional fashion, such as in a television system, or in three-dimensional fashion such as in a semi- transparent full image projection. Associated logic circuitry determines whether the full 3-D transparency is to be produced, in which case all images on the disk are to be illuminated, or whether swim through will occur, either on an image at a time or on a "ham slice" projection basis.

Abstract: An apparatus for determining the time of the closest point of approach of an object such as a taxiing aircraft includes a microphone (12) producing a signal in response to the sound energy of the engines of the aircraft. Low and high pass filters (16,18) are also provided to receive the signal and pass low frequency signals having a frequency less than or equal to 1 KHZ and high frequency signals having a frequency greater than or equal to 1.5 KHZ respectively. A demodulator (24,26) receives the signals from both the high and low pass filters and is operable to produce a low frequency envelope from the low signal and a high frequency envelope from the high signal. Finally, a comparator (28,30,32) receives the low frequency envelope and the high frequency envelope and compares the amplitudes so as to provide a signal at the point in time when the amplitude of the low frequency envelope exceeds the amplitude of the high frequency envelope, this signal indicating in real time the point of closest appraoch of the aircraft.

Abstract: A protection relay system is described which detects faults in an electric power system having a circuit breaker, by using a current and a voltage of the electric power system. The protection relay system includes an input conversion unit 100a adapted for connection to the electric power system to receive the current i and voltageV, and converting the magnitude and/or the phase of the current and voltage to produce at least two electrical quantities, and for outputting the second input signal, the voltagev, without conversion. A comparator 7 is connected to receive the first, second and third electrical quantities for comparing the first and second electrical quantities to produce a first logical state and comparing the third and fourth electrical quantities to produce a second logical state signal, cyclically. A digital data processing unit 8 judges whether a specified logical condition between the first and second logical state signals holds for a predetermined count corresponding to a predetermined electrical angle, and produces a protection relay output signal TM based on the result. The protection relay output signal is adapted for tripping the circuit breaker.

Abstract: The invention relates to gas analysers e.g. for analysing the carbon monoxide content of flue gas. It is known to test e.g. for carbon monoxide content, by directing infra-red radiation through a gas in a wavelength absorbed by carbon monoxide, and to use detectors for infra-red radiation, the level of radiation received by the detectors being utilised to evaluate the carbon monoxide content of the gas. The object of the invention is to provide gas analysing equipment which avoids the problems of taking gas samples from a flue and avoids the problems known in in situ equipment employing a beam splitter and two detectors where the detectors must be substantially identical in character. The objectives of the invention are met by a gas analyser characterised in that two detectors (8,9) are provided on to which infra-red radiation is to be focussed there being a beam splitter (6) sited between a collecting lens (4), to focus radiation on the detectors, and the detectors, either a gas cell (7) said gas cell containing a sample of gas being analysed, or an equivalent means, sited between the beam splitter and the detector (8), a pass filter (5) sited between the radiation source and the detectors, to transmit radiation in a waveband absorbed by the gas under analysis, and there being means (11 or 12) to eliminate the part of the said radiation specifically absorbed by the said gas in that waveband adapted to be positioned periodically in the path between the radiation source and the detectors in addition to or in place of the band pass filter (5).

Abstract: There is disclosed a method for imparting a decorative or printed pattern to the surface of rotationally molded products during their manufacture and a pattern transfer used in that method. The decorative pattern is formed on a transfer sheet film as a coating of pigments dispersed in a hydrocarbon wax which overlays a release agent, such as a silicone coating on the sheet film. The decorative wax pattern is applied to a preselected area of an inside wall of the rotational molding cavity by positioning the pattern transfer against the surface of the wall and burnishing the pattern onto the interior wall of the mold cavity. Thereafter, the particulate molding resin is charged to the cavity and the product is molded in a conventional procedure, resulting in transfer of the pattern into the resin, with the pigments incorporated in the resin product and with most of the wax excluded from the product.

Abstract: The production of two coplanar ray bundles penetrating one another at a predetermined angle is problematical to the extent that adjustment is difficult and the angle of penetration cannot be stably fixed. In order to solve this problem, an optical device is proposed which has a beam splitter that splits the incident beam into two component beams and ensures that the angle between these component beams remains stable, a telescopically imaging system being provided for bringing together the two component beams at an angle which likewise remains stable. As a result of this design, it is possible to choose the distance of the apparatus from the optical component or object and the angle of penetration independently of one another, the application of the optical device thereby being substantially facilitated. The beam penetration angle can be adjusted easily and in a stable fashion. Variations in the distance of the penetration surface are facilitated by a simple optical compensation. <IMAGE>
