Abstract: A system includes a relay, an actuation circuit, and an actuation delay circuit. The relay is coupled to a source of an input voltage or current waveform. The relay includes an actuation coil. The actuation circuit detects a peak or valley of a rectified voltage ripple waveform. The rectified voltage ripple waveform is generated from the input voltage or current waveform. The actuation circuit also causes an actuation voltage to be provided to the actuation coil. The actuation delay circuit delays the actuation circuit from providing the actuation voltage. The actuation delay circuit is configured based on the peak or valley of the rectified voltage ripple waveform. The actuation delay generated by the actuation delay circuit causes the relay to begin allowing current to flow to a load device at a time coincident with a zero-crossing time value of the input voltage or current waveform.

Abstract: A gas trap includes a sample enclosure, a bubbler enclosure, an agitator, and a brushless, DC motor. The sample enclosure has a liquid inlet, a gas sample outlet, and a sample enclosure wall with a sample enclosure wall portion and a shared wall portion. The bubbler enclosure has a bubbler air inlet, a bubbler air outlet, and a bubbler enclosure wall with a bubbler enclosure wall portion and the shared wall portion. The sample and bubbler enclosures are fluidly coupled through the shared wall portion so that sufficiently pressurized bubbler air entering through the bubbler air inlet maintains the drilling fluid in the sample enclosure at a level determined by the location of the bubbler air outlet when the liquid inlet and the bubbler air outlet are both submerged in the drilling fluid.

Abstract: A method is provided for transmitting an email message from a sender to a recipient, the recipient capable of receiving email messages compliant with American Standard Code for Information Interchange (ASCII). However, one or more of the sender or other recipients have a non-ASCII email address. Accordingly, mapped ASCII email addresses are created for each of the non-ASCII email addresses. A username is generated as a mapping of the non-ASCII email address using a predefined mapping algorithm. A domain name is selected from one or more predefined domain names. The username is concatenated with the domain name to create the mapped ASCII email address. Then, the non-ASCII email address is replaced with the mapped ASCII email address and the email message is sent to the selected recipient.

Abstract: A piezoelectric borehole source capable of permanent or semipermanent insertion into a well for uninterrupted well operations is described. The source itself comprises a series of piezoelectric rings mounted to an insulative mandrel internally sized to fit over a section of well tubing, the rings encased in a protective housing and electrically connected to a power source. Providing an AC voltage to the rings will cause expansion and contraction sufficient to create a sonic pulse. The piezoelectric borehole source fits into a standard well, and allows for uninterrupted pass-through of production tubing, and other tubing and electrical cables. Testing using the source may be done at any time, even concurrent with well operations, during standard production.

Abstract: Various mechanisms are disclosed for improving the operational efficiency of a virtual translation look-aside buffer (TLB) in a virtual machine environment. For example, one mechanism fills in entries in a shadow page table (SPT) and additionally, speculatively fills in other entries in the SPT based on various heuristics. Another mechanism allows virtual TLBs (translation look-aside buffers) to cache partial walks in a guest page table tree. Still another mechanism allows for dynamic resizing of the virtual TLB to optimize for run-time characteristics of active workloads. Still another mechanism allows virtual machine monitors (VMMs) to support legacy and enlightened modes of virtual TLB operation. Finally, another mechanism allows the VMM to remove only the stale entries in SPTs when linking or switching address spaces. All these mechanisms, together or in part, increase the operational efficiency of the virtual TLB.
