System to aid a driver to determine whether to change lanes

Abstract: A vehicular vision system to aid a driver of a vehicle to determine whether it is safe to change lanes includes a camera having a field of view such that the field of view corresponds to at least a portion of an area proximate the vehicle. The system also includes an object identifier electrically coupled to the camera, a distance determiner which determines a distance of the object which is in the field of the camera, and a display electrically coupled to the camera which displays an image generated by the camera and provides an indication of the type of object which is in the field of view of the camera and the distance of the object from the vehicle.

Packaged information systems

Abstract: An embodiment of this invention relates to an intelligent lighting device that can receive signals and change the illumination conditions as a result of the received signals. The lighting device can change hue, saturation, and brightness as a response to received signals. One example of using such a lighting device is to display particular colors as a response to certain events. Among others, embodiments may include vehicle lighting systems, an information cube, a back lighting system for a display panel, and an indicator of a condition of a package.

Semi-conductors with partially and with completely filled3d-lattice bands

Abstract: Attention is drawn to a class of semi-conductors or insulators with incompletely filled 3d bands. Their lack of conductivity, if the number of electrons per atom is an integer, is explained by the circumstance that a moving electron will have a large probability of being withdrawn to the initial atom, if only the potential barriers to be penetrated are sufficiently high to reduce the frequency of transition below a certain limit. This inhibiting factor disappears, if for ions of equal electronic levels the number of electrons per atom differs from an integer. In the case of NiO this condition is fulfilled if an electron is brought by thermal excitation from the lattice 3d band into the somewhat raised and less occupied levels a, a' (figure 1); these levels belong to Ni ions adjacent to a vacant Ni lattice point introduced by the deviations from stoichiometry, and two of these Ni ions are at the absolute zero Ni3+ ions. An analogous conduction mechanism holds for non-stoichiometric Cu2O, with a completely filled 3d band (figure 2). Photoconductivity is generally observed with substances with completely filled zones and never with substances of the NiO type. A tentative explanation is given for this fact on the basis of the model of figure 1 and figure 2. In non-stoechiometric ZnO vacant oxygen lattice points are assumed (figure 3); in that case the calculation of the lattice levels shows that at the lattice holes one Zn2+ is converted into Zn, whereas in the lattice the additional electrons form Zn+ ions, as will be the case after thermal transitions of the electrons belonging to these Zn atoms into the lattice 4s band.

Computer-based medical image distribution system and method

Abstract: This invention relates to an object-oriented system and method for easily and rapidly distributing medical images from existing picture and report storage systems to a plurality of heterogeneous client workstations. The system includes one or more interface engines, for providing image objects with uniform structure regardless of the type of existing system on which they are stored, and image server middleware, for managing the distribution of image objects. The system also includes a security object server, for authorizing user access to the image distribution system and to particular objects, a personalization object server, for providing user interface preferences and client workstation capabilities, and a web server, for downloading initial access pages and user interface components. The system implements a method for medical image distribution according to which image data stored in existing picture storage systems is first converted into uniformly structured image objects before being composed for downloading to client workstations for user viewing. The system and method of this invention are easily extensible both for added function and for added performance. The system and method of this invention are preferably implemented according to CORBA standards.

A Superstructure in Spinels

Abstract: IN 1935, E. Kordes1 recognized that LiAl5O8 has nearly a spinel structure, but he observed a large number of extra lines, which he could not explain. A. Hoffman2 prepared the corresponding compound LiFe5O8, which again was recognized as having nearly spinel structure. We found3 that the powder diagrams of LiFe5O8 correspond with a primitive cubic lattice with a lattice constant of 8.33 A. The space group was found to be very probably P433 (or P413) and the positions of the atoms (in the notation of the International Tables, 1935) are: with Δ3, Δ4, Δ5 and Δ6 approximately 0.007 and Δ1 and Δ2 still smaller.
