The invention relates to the technical field of radar, in particular to a millimeter-wave quasi-optical integrated dielectric lens antenna and an array thereof. The array consists of a microstrip integrated antenna, a dielectric lens, an objective lens, an array base, a reflecting mirror, a protective cover and a beam transfer switch; one end face of the dielectric lens is a hemisphere or an ellipsoid, while the other end face is a cylindrical section; the microstrip integrated antenna is generated by an dielectric substrate, the front surface of the dielectric substrate is closely adhered tothe cylindrical section of the dielectric lens and serves as a feed source, and the back surface is grounded; the hemispherical or ellipsoidal end face of the dielectric lens is an antenna radiating surface; the length of the cylindrical part of the dielectric lens can be changed; the antenna array is arranged into a linear array or an area array; the array base and the reflecting mirror have conical quasi-optical reflecting mirror surfaces; the focus of the objective lens of the linear array or the area array aligns with the central line of the dielectric lens; the protective cover is arranged outside; and the antenna array is controlled by the beam transfer switch. The antenna structure has strong shock resistance and dust prevention, and is suitable for millimeter-wave radars for planes, automobiles and ships, and receiving/emitting sensing of communication equipment.

Coaxial catheter instruments for ablation with radiant energy

InactiveUS20050038419A9Rapid and effective photoablationLess timeStentsUltrasound therapyCoaxial catheterTarget tissue
Ablation methods and instruments are disclosed for creating lesions in tissue, especially cardiac tissue for treatment of arrhythmias and the like. Percutaneous ablation instruments in the form of coaxial catheter bodies are disclosed having at least one central lumen therein and having one or more balloon structures at the distal end region of the instrument. The instruments include an energy emitting element which is independently positionable within the lumen of the instrument and adapted to project radiant energy through a transmissive region of a projection balloon to a target tissue site. The instrument can optionally include at least one expandable anchor balloon disposed about, or incorporated into an inner catheter body designed to be slid over a guidewire. This anchor balloon can serve to position the device within a lumen, such as a pulmonary vein. A projection balloon structure is also disclosed that can be slid over the first (anchor balloon) catheter body and inflated within the heart, to define a staging from which to project radiant energy. An ablative fluid can also be employed outside of the instrument (e.g., between the balloon and the target region) to ensure efficient transmission of the radiant energy when the instrument is deployed. In another aspect of the invention, generally applicable to a wide range of cardiac ablation instruments, mechanisms are disclosed for determining whether the instrument has been properly seated within the heart, e.g., whether the device is in contact with a pulmonary vein and/or the atrial surface, in order to form a lesion by heating, cooling or projecting energy. This contact-sensing feature can be implemented by an illumination source situated within the instrument and an optical detector that monitors the level of reflected light. Measurements of the reflected light (or wavelengths of the reflected light) can thus be used to determine whether contact has been achieved and whether such contact is continuous over a desired ablation path.

Amplification relay device of electromagnetic wave and a radio electric power conversion apparatus using the above device

The present invention provides an amplifying repeater, which is constructed in such a manner that a ferrite core is inserted into a coil with a pre-determined number of winds to increase an induced electromotive force caused by an increase in flux linkage using a time-varying magnetic field of electromagnetic waves at a position distant from various electromagnetic wave generating sources by a predetermined distance and the induction coil and a variable condenser for inducing resonance are connected to each other to increase current while reducing a resistant component existing in the induction coil to intensify and amplify the magnetic field of electromagnetic waves. Furthermore, the present invention provides a wireless power conversion charging device using the magnetic field of electromagnetic waves, which is located between an electromagnetic wave generating source transmitter and a receiving coil or attached to the transmitter and receiving coil. The wireless power conversion charging device includes a rectifying diode for rectifying an electromotive force induced in a construction in which a resonance and impedance matching variable condenser is connected to a coil in series or in parallel in order to transmit maximum induced power to a charging battery that is a load using electromagnetic waves amplified by the amplifying repeater, and a smoothing condenser for smoothing the rectified voltage. Accordingly, charging power required for various small power electronic devices can be provided and power can be supplied to various loads.

Shelf-like display machine and image display method

The prior art in this field had a display portion of electronic paper at a part of a shelf and showed a problem that the display portion and the goods were hardly co-related to each other in response to an arrangement of the goods. In addition, it was necessary to prepare a special display substrate for changing all the shelf lengths into a display portion and its price was expensive. It was necessary to provide a signal line and a wiring for power supply up to the display portion and so it was necessary to perform a wiring at the shelf surface with opaque raw material or perform a connecting work for the wiring every time when the shelf was transferred. In view of the foregoing, plural images (either still images or animations) arranged in response to the number of stages of the shelves to be displayed are irradiated with a light source after each of the images is corrected in correspondence with the optical path length ranging from the light source to the end of each of the shelves, each of the images is guided to the end of each of the shelves by plural reflector members and then the images are displayed at the ends. In addition, each of the images is guided to the end of each of the shelves by plural reflector members and the images are displayed at the ends after plural images (either still images or animations) arranged in response to the number of stages of shelves to be displayed are irradiated by the light source and the optical path lengths ranging from the light source to the end of each of the shelves are set to be substantially the same to each other.

Media spooler system and methodology providing efficient transmission of media content from wireless devices

A media spooler system is described that provides a methodology for efficient transmission of media content from client devices, such transmission of digital images from wireless digital cameras. The media spooler or gateway addresses wireless transmission problems by acting as a protocol gateway between a thin-client device and a target host or server (supported by a server infrastructure). More particularly, the media spooler of the present invention acts as a protocol gateway between thin-client devices (e.g., “mobile visual communicator” in the form of a wireless digital camera) and server infrastructure (e.g., server-based computer systems or “Web servers” of a photographic service provider). This task entails accepting multiple, simultaneous connections from various client devices (e.g., wireless digital cameras), extracting information from those devices (e.g., digital photographs or other media content), and then uploading that information to the target server infrastructure. In basic operation, the media spooler queries each client device for the information (e.g., media, such as pictures) the client device thinks should uploaded, and then the media spooler queries the server infrastructure for the subset of pictures that have not been already uploaded. This improved coordination or synchronization of information between a device and target host allows for efficient recovery of dropped cellular data calls by essentially allowing the media spooler to “pick up where it left off.”

Actuating device and system exploiting the actuating device

A system having a machine having the function of reproducing an information recording medium, in which the system executes a program recorded on the recording medium by sending a machine actuating command signal to the machine by user actuation and by receiving signals from the machine. The system includes a main body portion of a machine, and a control unit for controlling the machine connected to the main body portion of the machine. The control unit has a housing, a plurality of control sections mounted on the housing actuated by the user with fingers, and a vibration motor mounted via a vibration motor mounting portion provided in the housing. The vibration motor includes a motor casing, a shaft rotatably supported by the motor casing, and an eccentric member mounted on the shaft. The eccentric member has a rotor and a plurality of coils mounted on the rotor which is mounted on the shaft. The vibration motor also includes a magnet mounted on the casing for facing the eccentric member, and a supplying member for supplying the driving current to each coil. The eccentric member is rotated when the driving current is supplied to each coil to cause vibrations of the vibration motor itself, with the vibrations being supplied via the housing to the user. This permits the vibrations to be felt by the user to make possible execution of the program excellent in simulated presence feeling.
