20120321254 | SAFEGUARD DEVICE FOR AN INTERFACE OF A FIBRE ADAPTER - The present invention relates to a field of optical fibre communication. A safeguard device for a fibre adapter used to connect an input optical fibre connector with an output optical fibre connector is provided. In a preferred embodiment, the safeguard device comprises a shutter and a shutter locking unit. The shutter is operably provided at an interface of said fibre adapter to allow the interface to switch between an open position and a closed position, wherein, the shutter at least shuts off the optical beam emitted from the input optical connector when in said closed position. The shutter locking unit is adapted for selectively locking the shutter in the open position or in the closed position. The safeguard device for the interface of the fibre adapter is configured to lock the shutter in the conventional fibre adapter to stably hold the interface of the fibre adapter in an open position or in a closed position, especially, to lock the shutter in the closed position to shut off the optical beam emitted from the input optical fibre connector so as to effectively prevent the emission leakage of the optical beam from the input optical fibre connector, thus avoiding potential safety hazard to the user. | 12-20-2012 |
20150078665 | HANDWRITTEN SIGNATURE DETECTION, VALIDATION, AND CONFIRMATION - Technologies may provide for detecting, validating, or confirming the validity of a handwritten signature. A logic architecture may be employed to detect a digital handwritten signature and validation data associated with a signature event, and to send the signature and the validation data to a trusted server.

20140151562 | Adaptive reflectivity for performance improvement on radiation detectors - Systems, devices, processes, and algorithms for adapting and/or adjusting a reflectivity of a reflector in a radiation detector. The reflectivity can be changed by a reflectivity control signal that is generated based on an estimated count rate of events so as to adjust a probability of a photosensor detecting light resulting from the event via, for example, a scintillation event. By adjusting the probability, an energy resolution of the radiation detector can be optimized. The reflectivity of a reflector can be changed by changing a state of a thin film, a liquid crystal layer, or a suspended magnetic particle layer. | 06-05-2014 |
