IPC: H04B3/23
Filed: 2002-06-24
Abstract: Disclosed is a communication system having stations mutually coupled through a communication channel, wherein at least one of the stations is provided with echo cancelling (EC) means. The EC means comprise: adaptive EC means arranged for simulating linear echo effects in said station, a subtracter coupled to the adaptive EC means and having a subtracter output, and non linear EC means coupled to the subtracter output for simulating additional echo effects in the communication station. The non linear EC means are arranged as harmonic suppressing post processor means coupled to the subtracter output for effecting non linear echo cancellation based on outputted higher harmonics. It is thus presented a low cost algorithm for full duplex acoustic echo cancellation, wherein a frequency dependent non linearity attenuation deals with non linearly distorted echo components. The system is well suited for robust hands free communication by mobile phones, video phones, conferencing phones etc.

Abstract: An improved seal arrangement in an assembly such as a valve assembly in which a compression member is provided to press a seal between the compression member and the valve body. In a preferred form, the compression member includes a recess which receives a first portion of the seal, and a second portion of the seal is disposed between the compression member and the valve body. In addition, a first inclined surface is provided in the recess of the compression member. The first inclined surface contacts a second inclined surface provided on the first portion of the seal. A third inclined surface on the compression member contacts a fourth inclined surface provided at a juncture between the first and second portions of the seal. Further, a fifth inclined surface is provided on the housing to contact a sixth inclined surface provided on the second portion of the seal. The arrangement creates lateral or side loads between the seal and the valve stem and also between the seal and the valve body to prevent or minimize leakage over a large number of valve operating cycles.

Abstract: A system and method for compensating switched mode amplifiers. The amplifier system includes an adaptive filter coupled to the output of circuitry that recovers the analog signal from the output of the switching amplifier circuitry. The adaptive filter derives an inverse transfer function of the forward path through the system. The derived inverse transfer function is used to generate a coefficient map which a compensation filter responsively compensates for from variations in the output load of the amplifier system. In the disclosed method, the deriving the inverse transfer function may further include calibrating the adaptive filter continuously, at system startup or in response to user demand.

Abstract: A method is described for segmenting an image of pixels into a number of fields. First
the method finds field separators (110) using the background of the image, in
particular white areas between, for instance, text fields. The segmenting includes
constructing:
     a tessellation grid of lines and nodes formed by extending the field separators along
at least one separation direction (in practice: horizontal and vertical) to an outer
border of the image, and   a set of basic rectangles enclosed by the lines of the tesselation grid of field
separators (110) and extended field separators (111).   
     Finally the fields are constructed by consolidating basic rectangles that are adjacent
without being separated by a field separator.

Abstract: A collapsible medical device for use, e.g. as a vascular filter (10). The device includes a mandrel (20) having a distal end (60) and a stop (40) spaced proximally of the distal end. A proximal length of the mandrel (20) extends proximally of the stop (40) and a distal length of the mandrel extends distally of the stop. A functional element (e.g. a vascular filter (50)) has a radially expandable body and includes a proximal slider (65) and a distal slider (60). The proximal and distal sliders are slidable along the mandrel (20) independently of one another such that the distance between the proximal slider and distal slider can be varied to effect different configurations of the functional element. In one method of using such a device, the functional element is urged distally to a treatment site by urging the mandrel distally. This causes the stop (40) to exert a distal biasing force on the distal slider (60), which acts against a restorative force of the functional element to axially elongate the functional element and reduce friction between the functional element and a wall of the vessel.
