A method for establishing a link key between correspondents in a public key cryptographic scheme, one of the correspondents being an authenticating device and the other being an authenticated device. The method also provides a means for mutual authentication of the devices. The authenticating device may be a personalized device, such as a mobile phone, and the authenticated device may be a headset. The method for establishing the link key includes the step of introducing the first correspondent and the second correspondent within a predetermined distance, establishing a key agreement and implementing challenge-response routine for authentication. Advantageously, main-in-the middle attacks are minimized.

The invention provides a method and apparatus to optimally estimate and adaptively compensate the temperature-induced frequency drift of a crystal oscillator in a navigational signal receiver. A Read-Write memory encodes two tables, one for looking up frequency drift values versus temperature readings and another one for valid data confirmation on the first table. The initially empty look-up table is gradually populated with frequency drift values while the receiver computes the frequency drift along with its position. During initial start of the receiver or re-acquisition of satellite signals, the stored frequency drift value corresponding to the current temperature is used. If no valid frequency drift value is available, the frequency drift value is computed based on the existing frequency drift values in the table. This invention reduces the Time-To-First-Fix (TTFF) of the receiver and enables the receiver to self-calibrate, thus no additional factory calibration would be necessary.

In a method of evaluating measured values for recognizing defect conditions due to material fatigue on aircraft parts, strain sensors (6) are applied on the critical locations of an aircraft (1) and measured values of outputs of the strain sensors are detected at different loading conditions, amplified and stored through several measuring circuits. An evaluating apparatus (9) derives, signals or indicates a material fatigue by comparison of current measured values with previous measured values. The critical aircraft parts (1) are impinged on with prescribed loading conditions by loading elements (3). The strain effect caused thereby is detected by measuring circuits. The evaluating apparatus (9) forms, for at least each loading condition and each measuring circuit, an allocated reference value and a permissible limit value range. If current measured values exceed the limit value range, this represents a material fatigue manifestation.

A three-dimensional microwell system that supports long term embryonic stem cell (ESCs) culture and formation of homogeneous embryoid bodies (EBs) is described. Microwell-cultured ESCs remain viable and undifferentiated for several weeks in culture and maintain undifferentiated replication when passaged to Matrigel®-coated, tissue culture-treated polystyrene dishes. Microwell-cultured ESCs maintain pluripotency, differentiating to each of the three embryonic germ layers. ESC aggregates released from microwells can be passaged for undifferentiated replication or differentiated to monodisperse EBs. The ability to constrain ESC growth in three dimensions advantageously provides for more efficient, reproducible culture of undifferentiated cells, high-throughput screening, and the ability to direct ESC differentiation by generating monodisperse EBs of a desired size and shape.

A switchable privacy display for an automotive vehicle comprises a spatial light modulator, a first switchable liquid crystal retarder and first passive retarder arranged between a first pair of polarisers and a second switchable liquid crystal retarder and second passive retarder arranged between a second pair of polarisers. A first switchable liquid crystal retarder comprises a two homeotropic alignment layers and a second switchable liquid crystal retarder comprises two homogeneous alignment layers. In a privacy mode of operation, on-axis light from the spatial light modulator is directed without loss to the passenger, whereas off-axis light has reduced luminance to reduce the visibility of the display to off-axis driver leaning towards the display. In a shared mode of operation, the liquid crystal layers are controlled so that off-axis luminance and reflectivity are unmodified.

The invention relates to a connecting device for a plug-and-socket connection containing two connectors, comprising a first part (1) with a first connector (2) and a second part (3) with a second connector (4). The first part (1) is equipped with an axle pin (5), and the second part (3) is equipped an axle bearing (6) for said axle pin (5), wherein said second part (3) is capable of being pivoted from a release position to a closed position about an axis of rotation (7) defined by the axle bearing (6), wherein the distance d1 of the center axis (16) of the first connector (2) from the axis of rotation (8) is equal to the distance d2 of the center axis (17) of the second connector (4) from said axis of rotation (8). In order to avoid jamming and permanent deformation during the connecting operation, the first connector (2) will always be in alignment with the second connector (4) during the pivoting operation. The connecting device of the invention is well-suited for the simple realization of plug-and-socket connections in the clinical field, in which a secure plug-and-socket connection is of paramount importance.

A method, system, computer program product, and protocol for digital rendering over a network is described. Rendering resources associated with a project are stored in a project resource pool at a rendering service site, and for each rendering request received from a client site the project resource pool is compared to current rendering resources at the client site. A given rendering resource is uploaded from the client site to the rendering service only if the project resource pool does not contain the current version, thereby conserving bandwidth. In accordance with a preferred embodiment, redundant generation of raw rendering resource files is avoided by only generating those raw rendering resource files not mated with generated rendering resource files. Methods for reducing redundant generation of raw resources are also described, as well as methods for statistically reducing the number of raw resource files required to be uploaded to the rendering service for multi-frame sessions. The preferred embodiments are particularly advantageous for remote rendering services at a different site from the client and connected across the Internet or a Wide Area Network, but may also be applied where the rendering service is co-located with the client site and connected thereto by a Local Area Network (LAN).

The present invention provides for a method of transferring operation of a mobile radio communication device from a first network to a second network, while connected to the said first network, and including the steps of identifying cells of the said second network, comparing signal power level of the identified cells with a threshold level and connecting to a cell of the second network identified as having a signal power level above the said threshold level such that that passage can be transferred from, for example, a 3G network to a 2G network can be achieved without requiring the 3G network to monitor the 2G network prior to such handover.

The invention relates to a two-wire transducer in automation engineering that outputs a measurement signal as an injected current. For the method to test the serviceability, it is proposed to increase the DC loop current (IS), independently of the measured value, from the minimum value towards the maximum value (ISM), and to measure the input voltage (UE) across the internal resistance of the transducer in the process, and to compare it with a definable threshold value (UES) that is greater than the minimum input voltage (UEM) required to maintain serviceability. If the input voltage (UE) falls below the threshold value (UES) before the DC loop current (IS) has reached its maximum value (ISM), the DC loop current (IS) is reduced until the input voltage (UE) reaches at least the definable threshold value (UES), and the error is signaled.
