Abstract: A storage system and method for dynamic duty cycle correction are disclosed. In one embodiment, a controller of a storage system provides a clock signal to the memory, receives the clock signal back from the memory, monitors the duty cycle of the clock signal received back from the memory, and in response to the duty cycle of the clock signal received back from the memory not meeting a target value, adjusts the duty cycle of the clock signal provided to the memory so that the duty cycle of the clock signal received back from the memory better meets the target value. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.

Abstract: A retractable syringe, plunger and releasable needle assembly including a retractable needle, a needle seal, a retaining member and an ejector member. The retaining member has a mating surface for mounting to a complementary mating surface of an interior wall of a syringe barrel. The plunger comprises a plunger outer, a plunger rod frangibly connected to a controlling member, a spring and a unitary plunger seal capable of engaging the retractable needle, wherein the plunger rod, plunger outer and the controlling member co-operate to releasably maintain the spring in an initially compressed state. After delivery of fluid contents of the syringe, the plunger forces the ejector member to release the retractable needle from the retaining member. Decompression of the spring at the end of depression of the plunger facilitates retraction of the retractable needle when engaged with the unitary plunger seal.

Abstract: A host power-on reset control circuit includes a comparator connected to receive both a divided version of a supply voltage and a reference voltage. The comparator generates and outputs a high digital state signal when the divided version of the supply voltage is at least as large as the reference voltage. The control circuit includes an output node connected to transmit a power-on reset control signal. The control circuit includes pulldown circuitry connected between the comparator output and the output node. The pulldown circuitry maintains the output node at a reset voltage level as the supply voltage rises to a host operational level, based on a signal present at the comparator output. The control circuit includes pullup circuitry connected between the supply voltage and the output node. The pullup circuitry maintains the output node at a non-reset voltage level after the supply voltage has risen to the host operational level.

Abstract: A retractable syringe, plunger and releasable needle retaining assembly are provided. The retractable syringe typically has a glass barrel and is prefilled with fluid contents before use. The releasable needle retaining system comprises a retractable needle, a needle seal, a retaining member and an ejector member that is operable to release the retractable needle from the retaining member. The retaining member has a mating surface for mounting to a complementary mating surface of an interior wall of a syringe barrel. The plunger comprises a plunger outer, a plunger rod frangibly connected to a controlling member, a spring and a unitary plunger seal capable of engaging the retractable needle, wherein the plunger rod, plunger outer and the controlling member co-operate to releasably maintain the spring in an initially compressed state. After delivery of fluid contents of the syringe, the plunger forces the ejector member to release the retractable needle from the retaining member.

Abstract: A flexible and extensible architecture allows for secure searching across an enterprise. Such an architecture can provide a simple Internet-like search experience to users searching secure content inside (and outside) the enterprise. The architecture allows for the crawling and searching of a variety of sources across an enterprise, regardless of whether any of these sources conform to a conventional user role model. The architecture further allows for security attributes to be submitted at query time, for example, in order to provide real-time secure access to enterprise resources. The user query also can be transformed to provide for dynamic querying that provides for a more current result list than can be obtained for static queries.

Abstract: Techniques are presented for reducing the DC voltage shift in a voltage regulator, particularly for high and ultra-high speed load switching operation. The regulator includes a power transistor, connected between an input supply voltage and an output node, and an error amplifier, having its output connected to control the gate of the output transistor, a first input connected to receive a reference voltage, and a second input connected to a feedback node. The regulator also includes a first resistance, connected between the feedback node and ground, and also a second resistance, a third resistance, and a first capacitance, where the feedback node is connected to the output node through a combination of the first capacitance in parallel with the second resistance and in series with the third resistance.
