  • Publication number: 20080097497
    Abstract: Pulmonary artery banding device (1) includes an inflating banding ring (2), to be installed around the patient's pulmonary artery (PA), an extending tube (3), and an insufflating button (4), the extending tube (3) connecting insufflating button (4) to the banding inflating ring, the banding ring being configured as a C-shape hydraulic sleeve forming a support for an inflating balloon, whose external wall (2a) is formed by a thin rigid silicon layer, and whose inside wall (2b) is formed by a thin flexible silicon layer, at the apart ends of the banding ring two brims being disposed (2c) to facilitate the size banding adjustment according with the pulmonary artery calibre (PA). The banding ring are provided with holes (2e) for passage of sutures fixating the ring on the pulmonary artery of the patient; the insufflating button being configured as a cylindrical reservoir and being provided with holes (4a) for sutures.

  • Publication number: 20080077075
    Abstract: Constructive disposition introduced in indeflator equipment applied in coronary angioplasty intervention represented by an evolutionary solution translated by improvements of construction nature in the locking/unlocking system of the embolus, providing a better control over the injection or removal of liquids and/or fluids in a balloon catheter, being such locking/unlocking system (A) presents a simple construction concept, with bigger reliability and durability, making easy its assembling, with small quantity of pieces, minimizing the possibility of non-conform mechanical performance, and additionally providing easy handling by nurses and/or auxiliary people, being that the operation to inflate or to empty the balloon catheter with liquid or fluid is made possible by the embolus (B) movement over the syringe (D), through the application of a force to inflate (Fi) or to empty (Fe) in the hold element (C), through an embolus rotation, since to inflate the balloon the system must be locked, where to that the lo

  • Patent number: 6985467
    Abstract: A method and system for rapidly acquiring a spreading code, used in a code division multiple access (CDMA) system. A first long code and a second long code, with each long code having a length of N chips, are generated. The first long code is different from the second long code. The first long code and the second long code are transmitted at a first phase angle and at a second phase angle, respectively, on a carrier signal, over a communications channel using radio waves. The first long code and the second long code may be transmitted at an in-phase (I) angle and at a quadrature-phase (Q) angle, respectively, on the carrier signal. From the communications channel, an I-phase acquisition circuit and a Q-phase acquisition circuit may acquire, in parallel, the first long code and the second long code from the I-phase angle and the Q-phase angle, respectively, of the carrier signal by searching, in parallel, N/2 chips, the first long code and the second long code.

  • Patent number: 6831905
    Abstract: A spread spectrum system having an assignor, a spread-spectrum processor and a transmitter. The assignor assigns each arriving information signal to a message-code signal. Each message-code signal is different then other message-code signals. The spread-spectrum processor generates a pilot code signal and processes the information signals with the message-code signals to generate spread-spectrum process-message signals synchronized to the pilot-code signal. A transmitter combines the spread-spectrum process-message signals and the pilot-code signal to generate a CDM signal. The transmitter modulates the CDM signal with a carrier signal for transmission over the communications channel.

  • Patent number: 6801516
    Abstract: A spread-spectrum system having an assignor, a spread-spectrum processor, a call processor, and an information-channel-mode modifier. The assignor assigns each information signal arriving at the spread-spectrum system to a message-code signal. Each of the message-code signals supports a pre-determined information-channel rate. Several information signals have different channel rates, and each information signal is assigned according to the required channel rate. The spread-spectrum processor generates a pilot-code signal, and spread-spectrum processes the information signals with the message-code signals to generate a plurality of spread-spectrum processed-message signals, respectively. The message-code signals are synchronized to the pilot-code signal. The call processor provides a call-type signal corresponding to the information signal rate for the several information signals having several different channel rates.

  • Publication number: 20030193914
    Abstract: A multiple access, spread-spectrum communication system processes a plurality of information signals received by a Radio Carrier Station (RCS) over telecommunication lines for simultaneous transmission over a radio frequency (RF) channel as a code-division-multiplexed (CDM) signal to a group of Subscriber Units (SUs). The RCS receives a call request signal that corresponds to a telecommunication line information signal, and a user identification signal that identifies a user to receive the call. The RCS includes a plurality of Code Division Multiple Access (CDMA) modems, one of which provides a global pilot code signal. The modems provide message code signals synchronized to the global pilot signal. Each modem combines an information signal with a message code signal to provide a CDM processed signal. The RCS includes a system channel controller is coupled to receive a remote call.
