Patent JP-2703405-B2 (JP)
IPC: H04S1/00
Filed: 1990-06-15
Granted: 1998-01-26
Abstract: A polyphonic (e.g. stereo) audioconferencing system, in which input left and right channels are time-aligned by variable delay stages (10a, 10b), controlled by a delay calculator (9) (e.g. by deriving the maximum cross-correlation value), and then summed in an adder (2) and subtracted in subtracter (3) to form sum and difference signals. The sum signal is transmitted in relatively high quality; the difference signal is reconstructed at the decoder by prediction from the sum signal using an adaptive filter (5). The decoder adaptive filter (5) is configured either by received filter coefficients or, using backwards adaptation, from a received residual signal produced by a corresponding adaptive filter (4) in the coder, or both. Preferably, the adaptive filter (4) is a lattice filter, employing a gradient algorithm for coefficient update. The complexity of the adaptive filter (4) is reduced by pre-whitening, in the encoder, both the sum and difference signals using corresponding whitening filters (14a, 14b) derived from the sum channel.

IPC: H01L43/06
Filed: 1997-09-09
Granted: 2006-10-18
Abstract: The method serves for dynamically compensating the offset voltage of a Hall device. The Hall device can have either a platelike structure with at least two contact pairs (AC, BD), or any other arrangement deriveable by conformal mapping. The contact pairs (AC, BD) are angled by e.g. 90 DEG . Each pair is supplied with a periodically alternating current whereby the phase shift of the supply currents corresponds to the spatial phase shift of the contact pairs and is e.g. 90 DEG . Superposition of the supplied currents results in a continuously spinning current vector in the Hall device. By measuring simultaneously the voltages (VAC, VBD) between corresponding terminals, a signal (VHO) consisting of the Hall voltage and a periodic offset voltage can be isolated. The offset voltage (VO) is eliminated by averaging the signal over at least one period.

Abstract: A method for testing for target bacteria involves adding bacteriophage to a sample to infect the bacteria in the sample; killing extracellular bacteriophage without killing phage-infected bacteria; amplifying bacteriophage remaining in the sample; and causing the bacteriophage to infect reporter bacteria and thereby produce an observable signal. The reporter bacteria are genetically engineered to have an indicator gene which on expression gives rise to a detectable signal, wherein expression of the indicator gene is initiated on bacteriophage infection of the bacteria.

Abstract: An improved safety syringe with retractable needle is provided which allows retraction of the needle into a hollow plunger by additional forward pressure on the plunger after the fluid is driven from the syringe. The present invention contemplates an improved syringe device with retractable needle, and a method of delivering fluid to a patient and retracting the needle within the syringe after the fluid is delivered. The syringe preferably includes a hollow plunger inserted into one end of a cylindrical barrel and a hollow needle attached to the other end of the barrel. Biasing means is attached to the barrel for biasing the needle toward the hollow plunger, and means is provided for releasing the needle into the hollow plunger by applying additional forward pressure upon the plunger after the plunger is fully extended into the barrel. The present invention is particularly convenient for the operator to use in a one-handed fashion and is relatively uncomplicated and easy to manufacture. Further, the present invention is non-reusable after the needle is retracted thereby preventing reuse of a potentially contaminated syringe.

Abstract: Method of management in a circuit-switched communication network (1), performed on or with the aid of at least a programmable apparatus (10) connected to said network. It comprises the step of computing and storing in an electronic memory a representation of the network based on B-blocking islands (Ni). Each B-blocking island consists of a set of nodes (A-G) linked in such a way that at least one route with at least an amount B of available concave resources exists between any pair of nodes in the set at the time t. The B-blocking islands (Ni) are organised in a hierarchy, wherein the hierarchical position of each Bi-blocking island depends on the choice of the values Bi used for defining said blocking island. The available bandwidth resources are thus summarised in order to reduce the complexity of network management tasks. Bottlenecks in the network are highlighted. The B-blocking-island hierarchy can be incrementally maintained. Applications: distributed or centrally managed routing, price procedures, distributed management with distributed agents, network planning and explanation of allocation failures.

Abstract: Elementos colectores de partículas de tipo de impacto de CFB, unidos a soportes refrigerados. Un aparato para separar sólidos de un gas de combustión en una caldera de partículas de tipo de impacto, verticales y plurales, situados en el CFB en una pluralidad de filas alternadas. Los separadores de partículas de tipo de impacto emplean unos elementos suspendidos, sostenidos desde los tubos refrigerados por fluido que forman un canal colector, típicamente en forma de U, que separa las partículas de los gases de combustión transportados a través de separadores de partículas. Mediante la diferenciación de la función de sostén, de la forma de recogida requerida por consideraciones de actuación, las necesidades de resistencia de los materiales utilizados para constituir la forma de recogida se reducen, y la resistencia del material del que está hecho el sostén refrigerado por fluido es mucho mayor, debido a la menor temperatura de trabajo del material que comprenden el sostén refrigerado por fluido, lo que permite el uso de materiales de coste menor.

Granted: 2006-03-09
Abstract: A retinal camera is used to examine an eye, the camera including a light source having first and second sources emitting first and second wavelength bands. The first and second light sources are arranged to alternately produce light onto the retina such that the absorptivity of light of the first wavelength band by oxygenated blood is greater than the absorptivity of light of the second wavelength band, and the absorptivity of light of the first wavelength band by the oxygenated blood is less than absorptivity of light of the second wavelength band. Light is selectively focused from the first and second sources by an optical arrangement and imaging devices produce respective images of a portion of the retina illuminated with the respective wavelength bands. The images obtained by the imaging device are processed by the imaging device and processor to determine a retinal metabolic image based on haemoglobin oxygenation. In an embodiment of the invention light is scanned across the retina.
