Abstract:
A method of implanting and securing an implantable flow connector in a body of a patient for providing communication of a first space within the body of the patient with a second space within the body of the patient. The method includes providing a flow connector having a lumen having a first orifice and a second orifice, inserting a retention device into the first space within the body, subsequently inserting the flow connector through an opening in the retention device so the second portion of the flow connector extends into the first space within the body and placing the second space within the body over the retention device.
Abstract:
An apparatus and method for channel estimation decrease overhead and hardware complexity while supporting both Wiener-type channel estimation and Finite Impulse Response (FIR) filtering/Infinite Impulse Response (IIR) filtering in a wireless communication system. The apparatus includes a storage unit for storing coefficient sets for a plurality of channel estimation types. A controller selects one of the plurality of channel estimation types according to at least one of a type of a pilot signal and a reliability value of a channel parameter. An N-tap filter, including N multipliers and (N−1) adders, determines channel estimation values of data tones by using the coefficient sets for the selected channel estimation type.
Abstract:
A broadcasting system is provided, which includes an input unit including a character set button, and a broadcasting reception device. The broadcasting reception device includes a broadcasting information storing unit storing a PSIP, a broadcasting station title loading unit loading a broadcasting channel corresponding to a title information of a broadcasting station set by the character set buttons using the PSIP stored in the broadcasting information storing unit, and a broadcasting title data displaying unit displaying a broadcasting channel loading the broadcasting station title loading unit.
Abstract:
This invention relates to devices for navigating passageways in a body, and in particular, to a steerable catheter that can be used to navigate the tortuous anatomy of a body's vasculature. In one embodiment of the invention the deflectable catheter comprises an inner catheter body having a first strut spine member and a cantilevered second strut tang member. An outer catheter body is cooperatively associated with the second strut tang member and an actuator is cooperatively associated with the first strut spine member. The actuator is slideably engaged within the outer catheter body.
Abstract:
The present invention relates to devices for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart, and related methods of using such closure devices for closing the passageway. The method includes introducing a mechanical closure device into an atrium of the heart and transeptally deploying the closure device across the interatrial septum to provide proximation of the septum secundum and septum primum.
Abstract:
A self-magnetized motor includes a stator adapted to rotate by electromagnetic interaction with a rotator, a plurality of slot teeth formed on and surrounding a through-hole of the stator, and an excitation pole adjacent at least one slot tooth having fewer projections than remaining ones of the slot teeth. The projections are formed on ends of the slot teeth facing the through-hole of the stator. According to one non-limiting embodiment, the excitation pole may be formed between two slot teeth having fewer projections.
Abstract:
A method to facilitate the ability to engineer an organized microstructure within a monolithically homogeneous implantable biomaterial, particularly metallic alloys, is provided. By starting with an ultra-fine grained, equiaxed microstructure having an averaged linear grain size of less than 5 microns, a functionally graded microstructure is developed by establishing a temperature gradient across the cross sectional dimension. In the case of a tubular product form, this dimension would be framed by the outer and inner surfaces. By ensuring one surface is held at a substantially lower temperature than the other surface a temperature gradient is developed. The present invention also provides an implantable medical device which includes an organized microstructure. In accordance with the present invention, the organized microstructure includes a first surface region having said ultra-fine grained, equiaxed microstructure and a second surface region comprising a recrystallized, coarser grained microstructure having an average linear grain size of greater than 25 microns, wherein the first and second surface regions are separated by a transition region.
Abstract:
An apparatus for and method of deciding symbols in a M-ary phase shift keying (MPSK) system are provided. The apparatus includes: a linear transform unit performing linear transform, to which a phase error is applied, of a received pair of symbols; and a symbol decision unit deciding a transmitted symbol corresponding to the received pair of symbols according to the sign value of the transformed symbol pair. According to the apparatus and method, degradation of a symbol error rate caused by a phase error when an MPSK signal is demodulated can be improved and a phase error can be estimated through a simple method.
Abstract:
A connector preventing disengagement from a circuit board and a display device is presented. The connector includes a securing portion fixed to a surface of the circuit board and at least one protrusion extending from the securing portion. The connector is inserted into at least one through-hole in the circuit board.
Abstract:
A method for replaying DMB data and a DMB terminal implementing the same are provided. Part of the DMB data of a real-time DMB service is buffered in a replay buffer. Upon request for a replay during the DMB service, broadcasting data played from a predetermined time granule to a time of the replay request is searched for in the replay buffer and displayed on a display.
