Abstract: A photovoltaic system includes a first and a second photovoltaic generator (9, 11) which delivers electric energy, an inverter (4) which can be coupled to the PV-generators (9, 11) for converting electric energy of the PV generators (9, 11) to output AC energy, and a switchable coupling arrangement (3) for coupling the PV generators (9, 11) to each other and to the inverter (4). The coupling arrangement (3) is arranged functionally between the PV generators (9, 11) and the inverter (4) and designed to connect the PV generators selectively either in a series circuit arrangement or a parallel circuit arrangement to the inverter (4).  The PV system (1) can therefore expediently be operated with an intermediate circuit voltage which is higher than the maximum voltage of one PV generator for achieving improved efficiency whereas it can be switched to a lower intermediate circuit voltage when necessary, for example, in case of a ground connection fault, to maintain predetermined voltage limits.

Abstract: The invention relates to facial stimulation apparatus configured to be worn on the a user's head, and which uses the ear (14) as an anatomical reference to ensure correct and repeatable placement of skin electrodes (16a, 16b) over the human facial nerves (12a-e) to facilitate Electrical Muscle Stimulation (EMS). Use of the ear as an anatomical reference ensures repeatable positioning of the electrode in contact with a single predetermined localised region of the face corresponding to the insertion of the facial nerve truck (10) overlying the sylomastoid foramen.  The apparatus overcomes problems inherent in known devices and, in particular, requires no anatomical knowledge on the part of the end user for its safe and most effective placement.

On or neighboring the two longitudinal sides of the strand (20), one elastic thread (22) each is fed into the outer meshes (23) of the net. At specified, regular distances, the two elastic threads (22) are guided together and connected to one another. The distance is chosen such that the number of meshes (23) of the net between two connection points (24) in the longitudinal direction of the strand (20) corresponds to the number of meshes (11) of the hair net to be produced along the first or second dimension of the hair net. The two elastic threads (22) are connected by joining to one another by means of a sealing and/or melting process. A weakness (25) is introduced in the connection region (24).

Abstract: Methods and a system for mobile device activity classification or context determination. The device compresses and sends sensor data to a remote server together with a selected activity label during a training phase. The remote server receives labeled sensor data from a number of devices and generates a classification model. The model may be reduced to a subspace that represents the dominant model parameters. The subspace data structure, which may be a small matrix, is transmitted to the mobile device. The mobile device uses the subspace data structure to classify device activity as indicated by the device sensors. In one example, the sensor data is projected onto the subspace matrix, which results in estimates of state probabilities for the various predefined states, the dominant one of which is selected as the current state, or estimated state.
