Abstract: Common mode (CM) noise is substantially canceled in a switching power supply circuit such as a boost converter by providing a split inductor and analyzing the switching power supply circuit as a bridge circuit formed of the switch, portions of the split inductor and parasitic capacitances of respective portions of the power supply circuit. The bridge can then be balanced by addition of capacitance in parallel with the parasitic capacitance of a respective portion of the power supply circuit or dividing the split inductor such that a ratio of inductances of respective portions of the split inductor approximates a ratio of parasitic capacitances of the respective power supply circuit portions which may be measured or otherwise empirically determined. CM noise reduction of up to 40 db can be achieved without symmetric circuit design, addition of circuit elements or complex filtering having added cost, space requirements and power losses.

Abstract: A fault tolerant modem system is provided according to some embodiments of the invention. A modem can include modulators and/or demodulators that provide redundancy in the event one of the modulators and/or demodulators fail. Connectivity between modulators and demodulators, for example, can be used to propagate TDMA timing to connected modulators and/or demodulators. Moreover, redundancy can be provided using modulators and/or demodulators with three or more input/output ports.

Abstract: A method and system for controlling the cutting speed of a cutting device employable in an ocular surgical procedure is provided. The apparatus includes a control module, a variable gas pressure regulator arrangement configured to receive gas from a gas pressure supply, wherein the variable pressure regulator arrangement is connected to the control module and the control module is configured to regulate gas received from the gas pressure supply, and an accumulator configured to store gas received from the variable gas regulator arrangement at a selected gas pressure. Gas at the desired pressure is delivered from the accumulator to the cutting device. The gas may be air, and the variable gas pressure arrangement may include a single variable pressure regulator or multiple pressure regulators which typically are not variable with respect to the pressure delivered.

Abstract: An active linear regulator circuit in parallel with a filter capacitor of a switching voltage regulator injects current to a load only when the switching regulator and capacitor cannot supply adequate current to follow high frequency load transients in a manner which is compatible with adaptive voltage positioning (AVP) requirements. control of current injection and determination of the insufficiency of current from the switching regulator and capacitors is achieved by impedance matching of the linear regulator to the switching regulator. The linear regulator thus operates at relatively low current and duty cycle to limit power dissipation therein. By matching impedances and increasing the bandwidth of the switching regulator, filter capacitor requirements can be reduced to the point of being met entirely by packaging and/or on-die capacitors which may be placed close to or at the point of load to reduce parasitic inductance, as can the linear regulator.

Abstract: An anchor rope lock that locks the rope in response to tension exerted by the anchor, and that unlocks the rope for retrieval or adjustment in response to tension applied to the free end. A locking shoe is mounted on a horizontal pivot axis for pivoting towards locked and unlocked positions. The rope passes under a lower surface of the shoe and upwardly through a passage in a projecting toe portion. As the shoe pivots towards the locked position, the lower surface of the shoe moves towards the upper surface of an underlying base plate so as to compress the rope, and the passage in the toe of the shoe moves towards a vertical orientation so as to force the rope into a bend so that the anchor rope is held firmly at a fixed length.

Abstract: A multiple phase buck converter or boost converter, or buck-boost converter has an inductor in each phase. The inductors are inversely coupled. In a first embodiment, the converter includes a toroidal magnetic core with inductors extending under and over opposite sides of the toroidal magnetic core. The coupled inductors are thereby inversely coupled and have a relatively low ohmic resistance. In a second embodiment, the converter comprises a ladder-shaped magnetic core (i.e. having parallel sides, and connecting rungs). In this case, the inductors extend under the sides, and over the rungs. Each inductor is disposed over a separate rung. The ladder-shaped magnetic core is preferably disposed flat on a circuit board. Inverse coupling and low ohmic resistance are also provided in the second embodiment having the ladder structure.
