A vehicle information display apparatus receives multiple pieces of information on mobile vehicles, determines degrees of importance of the individual pieces of information according to specific conditions, and displays symbols of only those mobile vehicles of which importance falls within a predefined range or symbols of only a specific number of mobile vehicles selected according to their importance in graphic form with enhanced visibility.

Preferred embodiments of the present invention are directed to systems for phase measurement which address the problem of phase noise using combinations of a number of strategies including, but not limited to, common-path interferometry, phase referencing, active stabilization and differential measurement. Embodiment are directed to optical devices for imaging small biological objects with light. These embodiments can be applied to the fields of, for example, cellular physiology and neuroscience. These preferred embodiments are based on principles of phase measurements and imaging technologies. The scientific motivation for using phase measurements and imaging technologies is derived from, for example, cellular biology at the sub-micron level which can include, without limitation, imaging origins of dysplasia, cellular communication, neuronal transmission and implementation of the genetic code. The structure and dynamics of sub-cellular constituents cannot be currently studied in their native state using the existing methods and technologies including, for example, x-ray and neutron scattering. In contrast, light based techniques with nanometer resolution enable the cellular machinery to be studied in its native state. Thus, preferred embodiments of the present invention include systems based on principles of interferometry and / or phase measurements and are used to study cellular physiology. These systems include principles of low coherence interferometry (LCI) using optical interferometers to measure phase, or light scattering spectroscopy (LSS) wherein interference within the cellular components themselves is used, or in the alternative the principles of LCI and LSS can be combined to result in systems of the present invention.

Systems for highly efficient, in-vivo collection of modulated infra-red light are presented. Specifically, these devices are arranged in an important format with a view to integration with a wristwatch or other wearable device. An optical aperture of large surface area, specially distributed in an annular ring, receives radiation having been modulated in a tissue test site by blood flow. Radiation received about the annular aperture is redirected by a blazed grating or similar optical element at near perpendicular angles, into a radially distributed, condensing light pipe array and further toward a common axis. Radiation converges on the axis, thus increasing the energy density of the collected signal, before it is further directed via a conic element to a detector such as a photodiode. In some versions, these highly specialized optical paths may be formed into a single element of inexpensive plastic or other rigid substrate.

In a construction machine having an engine room and capable of efficiently collecting air flowing in the engine room, a heat exchanger provided at a first side of the engine, and a fan provided at the first side and rotating to generate around the engine a flow of cooling air, further includes an exhaust duct extending in a fan axial direction parallel with a rotation axis of the fan along the engine. The exhaust duct guides the flow of the air to collect the air flowing downstream of the fan in the fan axial direction, in a region extending in the fan axial direction, and discharges the air to an outside of the engine room.

A near-field optical probe has a flat support member having opposed flat surfaces, and a tapered through-hole extends through the support member and terminates at one of the flat surfaces in a narrow aperture. A light collecting layer having a plurality of reflective surfaces is disposed on the support member for collecting and focusing light passing through the narrow aperture. An optical detector disposed above the light collecting layer detects light passing through the light collecting layer.

An apparatus and method for interrogating and automatically identifying a radio-frequency tagged surgical instrument tray and its contents of RFID-tagged surgical instruments are disclosed. The surgical instrument tray and its contents come into contact with an RF signal transmitted by the RFID reader, and as a result, the RFID tags affixed on the instrument tray and the surgical instruments respond by transmitting back to the RFID reader data pertaining to the history of the surgical instruments. A data terminal, which is connected to the RFID reader, may contain data pertaining to the radio frequency tagged surgical instruments during packaging, and during the return of the surgical instrument trays to the packager, identifies the surgical instruments.

A computer-assisted inspection system provides customized workflow based on different types of inspections and other factors. The system can provide different rules that can be activated in response to valuation / pricing, rule-based validation and automatic grading. Features include flat car part picking, easy to use, inspectors can be geographically separated, and system is installable over the internet to provide efficient installation to far-flung install sites.

Embodiments of the invention include an optical system and an optical system module, coupled to a distal end of a fluorescence emission endoscope apparatus, an optical waveguide-based fluorescence emission endoscopy system, and a method for remotely-controlled, multi-magnification imaging of a target or fluorescence emission collection from a target with a fluorescence emission endoscope apparatus. An exemplary system includes an objective lens disposed in a distal end of an endoscope apparatus. The lens is adapted to transmit both a visible target illumination and a fluorescence-emission-inducing target illumination as well as fluorescence-emission and visible light from the target. The system can thus simultaneously provide low magnification, large field of view imaging and high magnification, high-resolution multiphoton imaging with a single lens system.
