  • Patent number: 7908504
    Abstract: A proposed smart batteryless backup device is designed for the reception of data transmitted by controlled equipment, backing up said data in the case of the controlled equipment power failure or in accordance with several program requirements, and also for the subsequent restoration. Proposed device improves trust level of the backup if device is powered by interface signal lines and doesn't have batteries and electrical characteristics of the backup device fluctuating due to humidity and temperature influences as well as during device lifetime.

  • Publication number: 20100150656
    Abstract: Protective flood barrier system on the base of mobile protective flood barriers is offered. Each of these barriers comprises two or more filled elongate sleeves, a web, connecting theirs web and forming means. Envelops of said sleeves and said web are made from flexible impermeable material. These barriers are convenient for protection of separate houses, the extensive areas, as walls of a water basin. They allow reducing wind-induced waves and can be used for repair of earthen dams. The high-efficiency means accelerating installation of barriers are provided.

  • Publication number: 20080197858
    Abstract: A calibration module, for use in calibrating a VNA, includes ports connectable to the VNA, calibration standards, and single pole multi throw (SPMT) switches. Each SPMT includes a single pole terminal, multiple throw terminals and a shunt terminal corresponding to each multiple throw terminal. A switching path is between each throw terminal and the single pole terminal, and between each shunt terminal and the single pole terminal. Each switching path includes at least one solid state switching element. The calibration standards are selectively connectable to the ports of the calibration module by selectively controlling the switching elements. Each port of the calibration module is directly connected to a throw terminal of one of the SPMT switches. Also, unique algorithm are provided for calibrating a VNA when using a calibration impedance that is a hybrid of a reflect standard and a transmission standard, which can be achieved using the calibration module.

  • Patent number: 7307493
    Abstract: A hybrid 180° microwave balun device is provided to convert an unbalanced RF signal at the common port into two radio frequency signals with equal amplitude and 180° phase difference at two differential ports. The hybrid device includes a coplanar waveguide connecting to the common port. A power divider separates the coplanar waveguide into two symmetrical slotline waveguides to carry balanced signals. Two broadband multioctave slotline to microstrip transitions constructed in a way that the microstrip lines carry 180° phase separated signals to the differential output ports.

  • Publication number: 20070270057
    Abstract: The present invention proposes to apply against dangerous natural phenomena (mainly hurricane) relocatable water pump stations using wave energy and having two states: operating state (for cold water pumping) and collapsed state (suitable for transportation). In collapsed state these stations have a severe less cross-section at least in one of horizontal directions. Such stations include reconfiguration means for theirs transforming from one said state to the second state and back.

  • Publication number: 20070133785
    Abstract: An audio clip is provided as a ringback tone for an incoming call. A specific audio clip may be dedicated for specific callers or for a group of callers. A processor detects an incoming call and determines if an audio clip is assigned for the caller based on communication information associated with the caller such as Caller ID. The processor may also determine that the original ringback tones should be provided to an individual caller. The audio clips may be downloaded to the processor by a user and may be assigned to specific callers by the user.
