Abstract: PCT No. PCT/FI92/00064 Sec. 371 Date Nov. 3, 1992 Sec. 102(e) Date Nov. 3, 1992 PCT Filed May 3, 1992 PCT Pub. No. WO92/16058 PCT Pub. Date Sep. 17, 1992.A method and a device for controlling a radio transmitter. In the method, the radio transmitter is alternately caused to assume an ON state in which a desired outbound RF power is transmitted, and an OFF state in which no RF power is transmitted, the RF power being determined in the ON state by using a power control signal (Vc) controlling the amplification of transmitter amplifiers (3, 4). For ensuring that the data period falls within the useful period of the transmitter, within which the value of the RF power to be transmitted is constant, a data stream (D2) is delayed with respect to the power control (Vc) when the transmitter is caused to assume the ON state.

Abstract: A system for long term releasing of medication in the mouth, and especially an intra-oral fluoride releasing system (IFRS) for releasing fluoride over a long term for inhibiting the formation of caries in the teeth. The system uses a holder (10,130) for retaining and protecting intra-oral fluoride tablets (100) or other intra-oral medicament in the form of fluoride releasing devices (IFRD). The holder (10,130) has a plate (30) with retaining sides  (40,140) and retaining posts (50,150,155) or a carrier. The tablet (100) will fit within the holder (10,130). The tablet (100) may be located in the carrier, or ligature bands (200) can be tied around the tablet (100) in order to releasably hold the IFRD within the holder (10,130). The system causes a level of fluoride to be maintained over a long term within the mouth which has been found chemically effective for caries control and without causing severe irritation to oral tissues.

Abstract: The apparatus comprises a first zone contain-ing a first receptor which specifically binds to the analyte and a sample application point: a second zone containing a solid  phase bound receptor which specifi-cally binds to the first receptor but not the analyte, the first and second zone  being in at least partial fluid contact.  There is a third zone containing a third receptor which specifically binds to the analyte and which carries a label.  The third zone is separated from the first zone to prevent fluid contact there-between. A fluid application device is in contact with at least the third zone.  The method comprises sequen-tially contacting the sample with a first receptor which specifically binds the analyte under conditions favoring formation of a complex between the first recep-tor and the analyte in the solution, contacting the complex containing solution with a solid phase bound second receptor which specifically binds to the first receptor under conditions favoring binding of the complex to the solid phase, displacing the liquid sample from the solid phase with a displacing solution, and contacting the solid phase bound complex with a third labelled receptor which binds to the analyte but not to the first or second receptor to bind the third receptor thereto, and determining the lavel in either bound or unbound to the complex as an indication of analyte in the sample.
