Mobile devices provide security based on geographic location. With such a technique, a mobile device may automatically check its current location against geographic information as to the location(s) in which it is permitted to operate. When the user attempts access to the device, the mobile device will prompt the user for his/her credential only if the geographic location matches an allowed location. The user gains access then by inputting information corresponding to the credential, e.g. username and password, of a valid user. In the examples, if the geographic location does not match an allowed location, the mobile device provides a warning to the user, and the user is not allowed to enter any credential information. Optionally, the mobile device may send an alert message about the device being taken outside a specified boundary, e.g. to report the situation to other personnel.

A solid state disk (SSD) caches disk-based volumes in a heterogeneous storage system, improving the overall storage-system performance. The hottest data blocks are identified based on two factors: the frequency of access, and temporal locality. Temporal locality is computed using a logarithmic system time. IO latency is reduced by migrating these hottest data blocks from hard-disk-based volumes to the solid-state flash-memory disks. Some dedicated mapping metadata and a novel top-K B-tree structure are used to index the blocks. Data blocks are ranked by awarding a higher current value for recent accesses, but also by the frequency of accesses. A non-trivial value for accesses in the past is retained by accumulating the two factors over many time spans expressed as a logarithmic system time. Having two factors, access frequency and the logarithmic system time, provides for a more balanced caching system.

The invention relates to a method of querying technical domains that recognizes the concepts represented by strings of characters, rather than merely comparing strings. It can be used to compute conceptual similarity between terms, The method employs string distance metrics and a cyclic progression of lexical processing to recognize constituent term concepts that are then combined to form full-term concepts by means of a grammar. Terms can be extracted and identified as being conceptually similar (or dissimilar) to other terms even if they have never previously been encountered. A key advantage is the ability to extract terms from documents based on the combination of a limited number of sub-concepts, This avoids the need for the prior identification of all possible terms that current methods require. A second key advantage is the ability to introduce or remove concepts and synonyms individually without the need to alter terms which the concept or synonym constitutes.

The plastic has distinct absorption bands throughout the entire NIR range and has a chemical structure and composition ensuring an extensive moisture barrier against water absorption and water release in a reliable and stable manner over time. The plate body advantageously comprises an amorphous, transparent copolymer based on cyclic and/or linear olefins.

An optical inspector includes a radiating source, a time varying beam reflector, a telecentric scan lens, a blocker, a focusing lens, an aperture, and a detector. The radiating source irradiates a first position of on the time varying beam reflector with a source beam. The time varying beam reflector directs the source beam to the telecentric scan lens, which in turn directs the source beam to a transparent sample. A portion of the source beam travels through the transparent sample to another surface. The blocker blocks scattered radiation originating at the other surface. Scattered radiation originating from the transparent sample is not redirected by the blocker and is focused by the focusing lens to a first focal plane. The focused scattered radiation passes through the aperture before irradiating the detector. The detector output an intensity measurement of the scattered radiation that irradiates the detector.

A light source transmits detecting light toward an object. The object reflects the detecting light and forms a reflected light. A sensor is used for sensing the reflected light. Then, an exposure control unit coupled to the sensor performs luminance convergence on the reflected light according to luminance of the reflected light sensed by the sensor. And a distance measurement device coupled to the sensor detects a distance between the object and the light source and/or the sensor according to an image position of the reflected light on the sensor.

A structure of an optical path for laser range finding includes a main body and a light-emitting unit assembled in the main body. The main body has a transmitting channel, a receiving channel and a calibration channel. The light-emitting unit is assembled in the transmitting channel. The light-emitting unit emits an external optical beam and an internal optical beam. The external optical beam is emitted through the transmitting channel. The internal optical beam is emitted to the receiving channel via the calibration channel. An included angle is defined between the external optical beam and the internal optical beam. A receiver is mounted in the receiving channel. Under this arrangement, the external optical beam and the internal optical beam do not interfere with each other.

A zone plate includes a plurality of consecutively arranged, adjacent, and alternating first and second regions. The first regions are arranged to be substantially transparent to a first predetermined wavelength of radiation and a second predetermined wavelength of radiation that is different from the first predetermined wavelength of radiation. The second regions are arranged to be substantially opaque, diffractive, or reflective to the first predetermined wavelength of radiation and substantially transparent to the second predetermined wavelength of radiation.

An object is to provide a display device which has high visibility and has a touch recognition function with a high degree of accuracy, by combining a liquid crystal layer where liquid crystals are dispersed in a polymer and a light emitting element. In a display device using a liquid crystal layer where liquid crystals are dispersed in a polymer, a light-transmitting spacer is provided so as to overlap with a light receiving element which has a touch recognition function. The light-transmitting spacer can prevent light incident on the light receiving element from being dispersed by the liquid crystals, while maintaining a cell gap in the liquid crystal layer, and thus achieve a touch recognition function with a high degree of accuracy with high visibility.
