Abstract: Methods and devices for blocking orifices and occluding cavities within a patient are provided. The device in one variation comprises first and second tubular members attached to a collapsible sealing element. The device can be placed through an orifice and the collapsible sealing element can be collapsed to seal the orifice. An embolic may be introduced distal to the sealing element to occlude a cavity. The device may incorporate a locking mechanism which can be engaged to lock the sealing element into the collapsed position. The device may incorporate a valve to prevent flow through the tubular members, for example to prevent egress of the embolic from a cavity. The device can be detached to provide a permanent seal of the orifice, and can retain the embolic within the cavity. The device may be used in conjunction with a stent or other retention device to assist the sealing element in maintaining the seal.

Abstract: The present invention includes a reservoir on a base supported at an elevation by a support member above a plurality of plants to be watered. A mechanical fill assembly, containing a flush valve and a float connected to a water supply line, automatically keeps the reservoir filled with water for extended periods. The plants are watered by gravity through a plurality of main valves in the reservoir that provide a controlled amount of water to main lines extending to each group of plants. Branch lines extend from each main line that terminate at perforated plant lines at each plant to be watered. A plant valve controls the amount of water each plant will receive on a continuous basis. In a further embodiment of the invention, a bird porch is attached to the reservoir to automatically provided a bird waterer and to provide a bird feeder. Also, a removable fertilizer tray can be provided to fertilize the plants.

Abstract: A heat exchanger is provided for transferring heat to a working fluid. The heat exchanger comprises a housing having a plurality of grooves formed in a surface of the housing. The grooves have a first end and a second end, and define fluid flow channels. Each channel has a fluid flow inlet and a fluid flow outlet. The fluid flow inlets of an alternating first set of channels are adjacent to the first end of the grooves, and the fluid flow inlets of a second set of alternating channels are adjacent to the second end of the grooves. The first set of channels and the second set of channels are arranged such that fluid in immediately adjacent channels flows in opposite directions.

Abstract: A digital delay locked loop uses a delay array to delay an input signal by an amount indicated by a delay code. A phase of the resulting delayed signal is compared to a corresponding phase of the input signal, and dependent on the comparison, the delay code is updated to indicate whether the delay array needs to provide more delay or less delay. The digital delay locked loop also uses a detection circuit that monitors for a predetermined condition of the delay code. In response to detection of the predetermined condition, the delay code is automatically reset to a value different than a value of the delay code present at a previous reset or initial startup of the digital delay locked loop.

Abstract: A SSTL memory interface pre-driver stage that uses a voltage regulator to generate a ‘virtual’ ground reference voltage is provided. The ‘virtual’ ground voltage reference, being greater than a zero volt ground voltage, allows low voltage transistors to be used, thereby improving interface performance and decreasing system power consumption. The pre-driver stage uses a biasing circuit to bias the voltage regulator, formed by a transistor arranged in a source follower configuration, to generate the ‘virtual’ ground reference voltage off which a voltage translator stage of the pre-driver stage operates to generate an output of the pre-driver stage.

Abstract: A SSTL interface voltage translator that uses dynamic biasing to translate an input signal to an output signal is provided. The voltage translator uses a first device that, dependent on a first bias signal, causes the output signal to be pulled down, where the first bias signal is dependent on the input signal. The voltage translator also uses a second device that, dependent on a second bias signal, causes the output signal to be pulled up, where the second bias signal is dependent on the input signal.
