  • Patent number: 9067011
    Abstract: A device for placement in an environment, particularly a humid environment, for delivery of medication to said environment. The device comprises a reservoir (103) having an orifice (104), a conveying unit for conveying a reservoir's content (106) through the orifice (104) and an actuator arrangement for driving the conveying unit. In order to provide a reliable delivery of medication in a humid environment, the conveying unit comprises an auger (110) extending in the reservoir (103).

  • Patent number: 8961498
    Abstract: Electronic pill (1, 11, 21) comprising a plurality of medicine reservoirs (2, 12, 22), each of the reservoirs comprising a discharge opening (3, 13, 23) covered by a removable cover (6, 16, 26). The pill comprises at least one actuator responsive to control circuitry for removing the cover from the discharge opening (3, 13, 23). The actuator can for example be a spring loaded piston (4) breaking a foil cover when dispensing the medicament. 5 Alternatively, the cover can be a rotatable disk (16) or cylinder (26) with an opening (17, 27) which can be brought in line with the discharge opening of a reservoir under the action of the actuator.

  • Publication number: 20110106063
    Abstract: Electronic pill (1, 11) comprising at least one medicine reservoir (2, 12) with a solid powder or granulate medicine, a discharge opening (3, 13) and an actuator responsive to control circuitry for displacing medicine from the reservoir (2, 12) to the discharge opening (3, 13). The medicine comprises a dispersion of one or more active ingredients—e.g., solids in powder or granulate form—in an inert carrier matrix. Optionally, the active ingredients are dispersed using intestinal moisture absorbed into the pill via a semi-permeable wall section (14).

  • Patent number: 6079820
    Abstract: A printhead which comprises a body with pressure chambers (13) and nozzles (14), a membrane (17) connected to the body so as to form one wall of the pressure chambers, and an actuator plate (25) comprising an actuator element (31) for each pressure chamber. A support plate (19) between the actuator plate and the membrane includes first portions (21) and second portions (23) with the first portions being movable relative to the second portions in the direction of the thickness of the support plate, a first portion being situated between each actuator element and the corresponding pressure chamber. The actuator plate has active regions (31) and inactive regions (33), the actuator elements being formed by active regions of the actuator plate. Adjacent actuator elements are separated from each other over substantially their whole length by slits (35) in the actuator plate. The actuator plate can be a ceramic multilayer actuator (CMA).

  • Patent number: 5899675
    Abstract: A pump 1 comprises a chamber 2 having a inlet opening 22 and an outlet opening 21. The chamber 2 extends between a first main wall 30 and a second main wall 40. The first main wall 30 is a triangular bottom wall of a body 3. The second main wall 40 is a part of a triangular bottom wall of a tub 4. The body 3 is tiltable relative to the tub 4 so that the volume of the chamber 2 is variable. The pump 1 comprises an outlet valve for blocking the outlet opening 21 when the volume of the chamber 2 is increased and an inlet valve for blocking the inlet opening when the volume of the chamber 2 is reduced. The outlet valve is formed by a first portion 31 of the body 3. This first portion 31 of the body blocks the outlet opening when the body is urged against the outlet opening 21. The inlet valve is formed by a second portion 32 of the body 3. This second portion 32 of the body blocks the inlet opening when the body is urged against the outlet opening 21.

  • Patent number: 5038570
    Abstract: A piston engine having a piston (13) journalled in radial direction with respect to the direction of movement. The rotation-free piston (13) is centered by means of two pairs of dynamic groove bearings (41,43), (47,49) with respect to a cylinder axis (39). The piston engine is particularly suitable for use in cryo-coolers.
