Provided is a forceps tip assembly capable of supporting a forceps tip with high rigidity in order to realize a laparoscopic surgery requiring a significant power with the forceps tip, such as an organ removal surgery which has been heretofore difficult to be performed by a robot for medical use. The forceps tip assembly includes: a forceps tip supporting member which has a supporting part for supporting a forceps tip and three leg parts which are disposed at even intervals in a circumferential direction around a central axis line C1 and fixed to the supporting part so as to protrude backward from the supporting part; and three back-and-forth moving members which are disposed at even intervals in a circumferential direction around a predetermined central axis line C2 extending in a front-to-rear direction, which have their front end portions coupled with the three leg pads swingably and slidably in a direction orthogonal to the predetermined central axis line C2 and which are mutually coupled together as relatively movable in the extending direction of central axis line C2.

A method for transmitting a ranging code from a base station to subscriber stations to prevent collision during a random access by the subscriber stations in an Orthogonal Frequency Division Multiplexing / Orthogonal Frequency Division Multiple Access (OFDM / OFDMA) communication system. The method includes allocating connection identifiers (CIDs) for identifying the subscriber stations, allocating group IDs to the CIDs to divide the subscriber stations into a predetermine number of groups, and allocating ranging codes for distinguishing subscriber stations in a group corresponding to each of the allocated group IDs.

An enhanced transmitter for wireless power transmission is disclosed. The transmitter may be able to transmit radio frequency (RF) waves or pockets of energy for charging or powering an electronic device. The transmitter may include antenna element arrangements for receiving RF waves from a plurality of wireless sources and process them using a dedicated RF integrated circuit (RFIC) and set of antenna elements for receiving RF input signals from a plurality of wireless power sources. A digital signal processor (DSP) may be used to control reception using the dedicated RFIC and antenna elements of reception and to control transmission of wireless power selecting the transmitting RFICs and configuration of antenna elements to send RF waves or pockets of energy to a wireless receiver. The frequency of RF waves received may be sampled through a down converter array and line addressing devices to send the signals received to a micro-controller including a proprietary algorithm which control switching and processing necessary for faster and enhanced wireless power transmission, thus improving transmission efficiency.

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.

An illumination system for a microlithography projection exposure apparatus for illuminating an illumination field (65) with the light from an assigned light source (11) comprises a pupil shaping unit (15, 30) for receiving light from the assigned light source (11) and for generating a predeterminable basic light distribution in a pupil plane (31) of the illumination system and a transmission filter (36) assigned to the pupil shaping unit (15, 30) and having at least one array of individually drivable individual elements for the spatially resolving transmission filtering of the light impinging on the transmission filter in or in proximity to a pupil plane (31, 35) of the illumination system, the transmission filter (36) being designed for generating a predeterminable correction of the basic light distribution. An illumination system of this type can generate a multiplicity of location-dependent intensity distributions in a pupil plane of the illumination system, a high transmittance being ensured. The location-dependent intensity distribution in the pupil plane generates an angle-dependent intensity distribution on the illumination field of the illumination system which can be optimized for a mask structure to be imaged.

A data transmission system using a human body as a signal transmission path includes a transmitter and a receiver. The transmitter uses a pair of electrodes which are held in close proximity to the skin of the human body. The transmitter transmits data to the receiver through the signal transmission path partly extending through the human body when a user carrying the transmitter touches a touch electrode of the receiver. The electrodes are integrated into a garment worn by the user in such a manner that the electrodes are kept in a closely facing relation to the skin of the user, thereby establishing the electrical path extending through the human body. With the integration of the two electrodes into the garment, the user wearing the garment as an everyday clothes or uniform can be easy and convenient to carry the transmitter for successful transmission of the data.
