Abstract: The present invention relates to secure paring of electronically controlled devices configured to communicate with each other. A medical system is provided comprising a first unit and a second unit, the system comprising a first communication link allowing a first group of data types to be transmitted between the first unit and the second unit, and a second communication link allowing a second group of data types to be transmitted between the first unit and the second unit. Different properties of the communication links may be used to ensure that certain data, e.g. during pairing of the two devices, can be transmitted in a more controlled way whereas other data can be transmitted in a less controlled way.

Abstract: An inhaler for administering medicament by inhalation, comprising: an inhalation channel (24); a rotatable dosing unit (16) which includes at least one dosing element (18) for providing a dose of medicament to the inhalation channel (24); and a dose counting unit (42) which comprises an electronic display (57), an electrical circuit for counting each dose of medicament provided to the inhalation channel (24) and driving the display (57) so as to provide an indication as to the usage of the inhaler, the electrical circuit including at least one switch which comprises a contact element which is one of opened or closed when a dose of medicament is provided to the inhalation channel (24), and a rotatable member (45) connected to the dosing unit (16) so as to be rotatable therewith, the rotatable member (45) including at least one cam surface (51, 52) which includes at least one cam (51a, 52a), each cam (51a, 52a) on each cam surface (51, 52) being configured, on rotation of the dosing unit (16) to provide a dose

Abstract: A clock signal generator in an integrated circuit semiconductor device and a method of generating a clock signal, the clock signal generator comprising: a semiconductor substrate (2); an oscillator unit (4) which comprises at least one support member (10, 12) which is fixed relative to the substrate (2), an oscillator arm (6) which is oscillatably disposed to the at least one support member (10, 12) with regard a reference position, which oscillator arm (6) includes first and second conductive sections (6a, 6b) at positions extended from the at least one support member (10, 12), and at least one biasing element (14, 16) for biasing the oscillator arm (6) towards the reference position; a driver (18) which is disposed at the substrate (2) in spaced relation adjacent one of the conductive sections (6a) of the oscillator arm (6), which driver (18) is configured in use to drive the one of the conductive sections (6a) of the oscillator arm (6) towards or away therefrom when an electrical signal is applied thereto;

Abstract: A counting device, comprising: an input 105, 107 for receiving an input signal having at least three distinct input states; memory means 810 for storing a count; and means 620 responsive to a predetermined sequence of input states of said input signal to vary said count, wherein said predetermined sequence includes the at least three input states.
