Abstract: Un instrument dentaire (10) à main comprend un moteur d'entraînement (13), un axe d'entraînement (12) fixé fonctionnellement au moteur d'entraînement (13) au niveau d'une extrémité de l'axe d'entraînement (12). Un outil dentaire (11) est fixé fonctionnellement à l'autre extrémité de l'axe d'entraînement (12). L'axe d'entraînement (12) tourne à l'intérieur d'un palier (60) à déplacement axial, de sorte que la rotation manipulée de l'outil dentaire (11) provoque le déplacement axial de la première partie (61) de l'axe d'entraînement à partir d'une seconde partie (62) de l'axe d'entraînement et par rapport à celle-ci. Le palier (60) à déplacement axial est amené à venir au contact d'un palier (51) provoquant ainsi la liaison de l'axe d'entraînement (12) du fait des forces de frottement produites par ce contact. Ceci permet d'obtenir une force suffisante de manière que l'outil dentaire (11) puisse être dégagé de l'instrument (10) à main.

Abstract: Methods of controlling fluid flow through microchannels by use of passive valves or stopping means in the microchannels are presented. The passive valves act as pressure barriers impeding flow of solution past the stopping means until enough force is built up to overcome the force of the pressure barrier. Well planned use of such stoppin g means acting as passive valves allows the flow of fluids through microchannels to be regulated so as to allow fluids to be mixed or diluted after being introduced via a single channel, or to be split into multiple channels without the need for individual pipetting. Flow throu gh the multiple channels can be regulated to allow a series of sister wells or chambers to all fill prior to the fluid flowing beyond any o ne of the sister wells or chambers. The filling of sister wells or chambers in this manner allows all wells or chambers to undergo reactions in unison. The use of air ducts to prevent trapping of air in the microchannels is also presented.

Abstract: A method and apparatus for tracking the position of a mobile unit (300) in a mobile radio communication system using information from earth-orbiting satellites and information received from the infrastructure of the system, wherein the infrastructure consists of equipment (400) associated with transmitting and receiving voice or data traffic to and from the mobile phone (300). An initial position of the mobile unit (300) is calculated using measurements from earth-orbiting satellites.    A positional difference between the initial position and a current position of the mobile station (300) is estimated using range measurements between the mobile unit (300) and the infrastructure (400). An accuracy value is next determined for the estimated positional measurement, and the accuracy value is compared to a threshold to determine whether the estimated positional measurement has an acceptable accuracy. If so the initial position of the mobile unit (300) is updated using the estimated positional measurement and the process is repeated using only range measurements between the mobile unit (300) and the infrastructure, otherwise a new initial position is determined from the earth-orbiting satellites and the process is repeated.

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 implemented 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 described which provides intermittent masking of the tinnitus wherein, at a comfortable 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 provides 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.
