摘要： A tactile screen for blind users is formed by a board with an array of holes filled with an electrorheological fluid and a membrane fixed on the surface of the board. The holes are equipped with electrodes forming electrically controlled valves which connect or disconnect the cavities under the membrane with the fluid on the back of the board. To set the membrane section over a valve to a certain state, the pressure of the fluid must be set to the desired valve and the valve must be opened. Another possibility is to form by electrodes, a bidirectional pump in each hole. The user is getting the information by immediately touching the membrane or by touching pins lifted by the membrane. By successively switching electrical impulses on all rows and columns of electrodes and evaluating the electrical signal capacitively coupled to the body of the user, the coordinates of the users fingertips are determined. In this way the board is used as an input device.

摘要： A broad area laser, with high efficiency and small far-field divergence, has an active layer, a first contact and a second contact, each having a width larger than 10 μm. An anti-wave guiding layer, which is positioned laterally with respect to the active region, is enclosed between the first and second contacts, wherein a refractive index of the anti-wave guiding layer is larger than a minimum refractive index of cladding layers. A minimum distance between the anti-wave guiding layer and a projection of one of the contacts on the plane of the anti-wave guiding layer is between 0 and 100 μm.
