摘要:
The invention provides a skin treatment device comprising a laser source (40) and focusing optics (50), such that a focal spot (18) is positioned in a dermis layer (24) of the skin to be treated. The laser beam (42) is powered and focused (16) such that a LIOB (laser induced optical breakdown) phenomenon is obtained, which affects the skin in order to stimulate re-growth of tissue. This in turn reduces wrinkles (30). The device may comprise wrinkle-determining means (52, 54, 56, 58). The focusing optics (50) may have a numerical aperture of at least 0.4. The invention also provides a corresponding method to treat skin, in particular to reduce wrinkles (30), by providing a focused laser beam (16) that causes LIOB in the dermis layer (24) of the skin. The advantage is that damage to overlaying epidermis layers may be avoided by the use of the very local LIOB phenomenon.
摘要:
Systems and methods for achieving sub-surface, highly spatially selective cardiac ablation by means of laser induced optical breakdown (LIOB) are disclosed. Damage to non-targeted heart and artery/vein tissue is to be minimized according to the present disclosure. A catheter enters the heart, e.g., via a vein, and catheter location is determined/confirmed. Laser pulses are guided through the optical path within the catheter and, at or near the catheter end, a focusing structure is provided that focuses the laser radiation through the non-targeted vein/heart tissue into the targeted tissue. In the focusing structure, laser induced LIOB occurs and related mechanical effects affect the targeted tissue.

摘要:
The interdental cleaner includes a source of liquid (22) and a control system (42) including a manual pump (26), for moving a selected amount of liquid, suitable for a single use, into a liquid pathway and there to a mixing chamber (53). A source of pressurized gas (30), such as a CO2 cartridge, is used to preload a selected amount of gas into a gas chamber (52). The control system includes a spring-loaded button (18), which upon operation results in the manual pump (26) being operated, forcing the selected amount of liquid into the mixing chamber, and then upon release, permits the pressurized gas in the gas chamber to enter the mixing chamber, breaking up the liquid therein into droplets and a liquid stream, and propelling the resulting liquid out of a nozzle portion (14) of the cleaner into the interproximal area of the teeth.

摘要:
An actuator comprises an electroactive polymer layer (402) and a stretchable electrode structure (403) disposed at a first side of the electroactive polymer layer and further a counter electrode layer (401) disposed on a second side of the electroactive polymer layer, wherein the ratio YC/YEAP of the elastic modulus YC of the counter electrode layer and the elastic modulus YEAP of the electroactive polymer layer is at least 10. When compressed transversally by the electrodes, the electroactive polymer will expand tangentially and the actuator will relax into a shape wherein the interior of the electroded region is substantially recessed parallel to the plane of the device, while a substantial portion of the area increase is absorbed by out-of-plane bends arising at the electrode boundary (duck mode). The invention can be embodied as optically reflective or refractive devices with variable geometry.
摘要:
A method of adapting an environment of a terminal (2) includes: —receiving data (27) from an external source at the terminal (2); —receiving monitoring data from a system for monitoring at least one user in the environment; and —controlling at least one output device for providing an output perceptible in the environment, the output being adjusted in dependence on the monitoring data. At least one segment including data pertaining to at least one mental state is retrieved from the data (27) from the external source, and the adjustment in dependence on the monitoring data is effected at least partly on the basis of the data pertaining to the at least one mental state.
摘要:
The invention relates to an actuator device (400) comprising an active layer (410) having directly or indirectly a skin layer (420) on top that can be touched by when in use by a user. The configuration of the active layer (410) can controllably be changed in an extension direction (x, y), and the skin layer (420) comprises a plurality of elevations (E) and intermediate recesses (R). Due to its structure, the skin layer (420) does not hinder conformation changes of the active layer (410) in the extension direction, while it provides favorable tactile characteristics of the actuator device (400). The active layer (410) may particularly comprise an electroactive polymer (EAP). The skin layer (420) may be composed of a plurality of grains isolated from each other, or it may comprise a thin surface layer (421) that is stiffer than the active layer (410).

The invention relates to a display device (100-300) that comprises an image display unit (IDU) for displaying a visual image in combination with an adjacent topology display unit (TDU) that can controllably change the topology on a tactile display surface (TDS). Hence both visual and tactile information can be represented and can be related to each other by a control unit (CU).
