Abstract: In an inkjet print head an actuation chamber substantially extends in a first direction and the actuation chamber is associated with a piezo actuator arranged to generate a pressure wave in the actuation chamber. The pressure wave propagates in said first direction. A nozzle is associated with the actuation chamber such that a droplet may be expelled through the nozzle upon generation of the pressure wave in the actuation chamber. A reservoir is in fluid communication with the actuation chamber via an inlet and an outlet of the actuation chamber. A pump means is provided for pumping ink from the reservoir, via the inlet, through the actuation chamber, via the outlet back into said reservoir. The print head is provided with a means for reflecting the pressure wave at the outlet of the actuation chamber for enabling to generate a sufficient pressure at the nozzle for expelling the droplet.

Abstract: An apparatus for selectively extending and retracting spikes includes spike actuating assemblies mounted to, and cooperating between, a first plate and a first slider frame, and a second plate and a second slider frame, pivotally mounted to the first plate and first slider frame respectively. Each spike actuating assembly contains a spike. The first slider frame is translatable to actuate the spike actuating assemblies to thereby extend and retract the spikes from the spike actuating assemblies. A cyclically alternating positioner is mounted on the first plate for moving the first and second slider frames relative to the first and second plates. The positioner has only a single actuating button adjacent the heel. Depressing the actuating button a first time causes the positioner to move the slider frames to extend the spikes. Depressing the actuating button a second time causes the positioner to move the slider frames to retract the spikes.

Abstract: The invention relates to a device for controlling an exhaust gas stream. Said device comprises a housing (1, 101) with at least a first, second and third connection (2, 3, 4, 102, 103, 104) that form links to a first, second and third exhaust gas conduit for conducting the exhaust gases of an internal combustion engine, a first sliding element (6, 106) with a displaceable first sliding rod (6a, 106a) and a first sealing member (6c, 106c) that is located on said rod, a second sliding element (7, 107) with a displaceable second sliding rod (7, 107a) and a second sealing member (7c, 107c) that is located on said rod and an actuator for a force-assisted actuation of the device. According to the invention, a link (4c, 104b) can be established between the first and the second connection and can be adjusted by means of the first sealing member (6, 106) and a link (3c, 103b) can be established and adjusted between the first and the third connection by means of the second sealing member (7c, 107c).

Abstract: The invention is a light therapy skin care device that includes light sources in a layout that is configured for lighting of human body's given skin surfaces (B) or its parts. Among light sources, there is a UV light emitting and a UV-free light emitting device, the light sources are connected to a controlled driver unit. The light sources are divided in two groups, where in the first group there are (1) UV light emitting light sources, in the second group (2) UV-free light emitting light sources, and at least one part of the light sources of the second group (2) emits polarised light towards the skin surface (B). The controlled driver unit is configured to control light emission of the light sources of the first (1) and second (2) groups and/or their proportion.
