  • Patent number: 7193214
    Abstract: Parametric processing capability is added to a typical sensor so that a target object can be more clearly distinguished from the background clutter in a given scenery. A polarizer with several segments of different polarization orientations is used to improve the typical sensor. The segments are sequentially advanced to pass therethrough infrared radiation images of pre-selected polarization orientations which are then collected by respective polarized frame grabbers. Image processing circuit processes these images to yield the polarization difference between any given pair of orthogonal polarizations. In a surveillance network, the polarization differences are subsequently used in the control center, to which such sensors are connected, to enhance the distinction of the observed objects against the background clutter suspended in the propagation medium.

  • Patent number: 7193252
    Abstract: In a photosensitive part 10, arranged from pixels A aligned in n rows and m columns, supply wiring lines 13a and 13b, which are electrically connected and apply transfer voltages to transfer electrodes 12a to 12d, formed of polycrystalline silicon, are installed so as to cover parts of the top surfaces of light-shielded pixels D. Dead zones for installing supply wiring lines, which existed priorly at the respective end parts in a horizontal direction of a photosensitive part, can thereby be eliminated and the photosensitive part can be made wide. Also, in the case where a plurality of the solid-state image pickup devices are used upon being made adjacent each other in the horizontal direction, parts at which image pickup is not carried out can be lessened. Also, the amount of lowering of the amounts of incident light on light-shielded pixels D can be corrected based on the output signals from light-shielded pixels D or other pixels A.

  • Patent number: 7193255
    Abstract: Floating conducting regions at floating potentials are placed on a substrate surface between adjacent conducting regions to which predetermined potentials are applied. This makes it possible to block the spread of a depletion layer to the substrate between the conducting impurity regions. Thus, the leakage of high-frequency signals can be suppressed. In particular, in a case where a floating conducting region is placed between a peripheral impurity region of a common input terminal pad and a resistor in a switch circuit device, it is possible to suppress the leakage of high-frequency signals from an input terminal to control terminals which become high frequency GND and to suppress an increase in insertion loss.

  • Patent number: 7193259
    Abstract: A thermally written magnetic memory device is disclosed. The thermally written magnetic memory device includes a plurality of thermally written magnetic tunnel junction devices. Each thermally written magnetic tunnel junction device includes a super-paramagnetically stable data layer. The data layer includes a high coercivity at a read temperature such that a bit of data previously written to the data layer at a higher write temperature can be read from the data layer at the read temperature. The data layer has a low coercivity at the higher write temperature and data is written to the data layer at the higher write temperature. Therefore, at the lower read temperature, the thermally written magnetic memory device is a read only non-volatile memory and the data stored therein can be read many times but new data cannot be written to the data layer at the read temperature.

  • Patent number: 7193261
    Abstract: A quantum supercapacitor having nanostrucutured material located between electrodes. The material includes clusters with tunnel-transparent gaps. The clusters have sizes within the range of 7.2517 nm?r?29.0068 nm, at which the resonant characteristics of the electron are exhibited. The size is determined by the circular radius of the electronic wave according to the formula r0=/(me?2c)=7.2517 nm (Plank constant , electron mass me, fine structure constant ?=1/137,036, speed of light c). The cluster size is set within the range r0?4r0; the width of the tunnel-transparent gap being ?r0=7.2517 nm. The energy in the supercapacitor is stored by means of controlled breakthrough of the material—a dielectric, with subsequent restoring thereof. The energy is stored uniformly along the whole volume of the material due to the resonant coupling of the electrons on the cluster. The maximum stored specific energy stored is 1.66 MJ/kg.
