Title: Data transmission method and radio link system
Inventor: MAKINEN JARMO
IPC: H04W92/12
Filed: 2000-03-06
Abstract: This invention relates to data transmission in a microwave link system particularly through point-to-multipoint connections. The arrangement according to the invention utilizes both frequency and time division duplex arrangement to simplify substation structures. In accordance with the invention a substation transmits at different times than it receives, and us es different frequencies for the transmission and reception. The central statio n, in turn, includes a duplexer unit, whereby it can both transmit and receive simultaneously when the transmission and reception frequencies are sufficiently apart. Such an arrangement achieves advantages of the time division duplex arrangement, such as e.g. an inexpensive substation structur e, without the drawbacks related to the time division duplex arrangement.</SDOA B>

Title: Method and apparatus for aligning optical interconnections between printed circuit boards
Inventor: MAHLAB URI
IPC: H04B10/00
Filed: 2000-09-28
Abstract: Method and apparatus for the alignment of optical interconnections between a t least one optical data transmission point (104) and at least one correspondi ng optical data receiving point (107). A collimated beam (201) of data carrying  light is polarized through an electrically-controlled light polarizer (108),  such as a spatial light modulator or a liquid crystal, which comprises an array of pixels. A focused beam (202) of the data-carrying light, emitted fr om the light polarizer, is obtained on the receiving point, by individually controlling the polarization of each pixel, and deflecting the direction of the collimated beam when emitted from the light polarizer, until a predetermined value of an electrical signal (current and/or voltage) representing the level of alignment is obtained. The collimated beam is further continuously and/or adaptively aligned by determining a desired current and a threshold current and/or voltage produced by an optical sensor  at the receiving point. A comparator circuitry compares the actual current produced by the optical sensor, to the threshold current, and a feedback loo p controls each individual pixel according to the comparison result.

Title: Tinnitus rehabilitation device and method
Inventor: DAVIS PAUL BENJAMIN
IPC: H04R25/00
Filed: 2000-03-17
Abstract: A tinnitus method and device for providing relief to a person suffering from  the disturbing effects of tinnitus is described. The method can be implement ed entirely in software to spectrally modify an audio signal in accordance with  a predetermined masking algorithm which modifies the intensity of the audio signal at selected frequencies. A predetermined masking algorithm is describ ed which provides intermittent masking of the tinnitus wherein, at a comfortabl e listening level, during peaks of the audio signal the tinnitus is completely  obscured, whereas during troughs the perception of the tinnitus occasionally  emerges. In practice it has been found that such intermittent masking provid es an immediate sense of relief, control and relaxation for the person, whilst enabling sufficient perception of the tinnitus for habituation and long term  treatment to occur. Advantageously the predetermined masking algorithm is specifically tailored to the audiometric configuration of the person. For example, the masking algorithm may be partly tailored to the hearing loss characteristic of the person. A tinnitus rehabilitation device used in conjunction with a personal sound reproducing system is also described.</SDO AB>
