Publication number: 20070028707Abstract: This invention involves a new housing for a liquid level detection device. More particularly, the new stillwell apparatus comprises, at least one tubular section, a means for extending the length of the stillwell, a conduit for delivering a cleansing solution to the bottom of the tubular sections, a gas inlet tube for determination of the presence of hazardous gases, and a means for pressure equalization. In addition this invention reveals novel installation, removal and cleansing methods making it possible to install, remove, and cleanse the stillwell from an exterior of a vessel, thereby eliminating the need for highly trained personnel to enter the vessel in order to install, maintain, cleanse, or remove the stillwell.Type: ApplicationFiled: June 29, 2006Publication date: February 8, 2007Inventor: Craig Nelson

Patent number: 7076635Abstract: A method and apparatus for reducing instruction ITLB accesses. In one embodiment, the method may comprise generating a next virtual fetch address corresponding to an instruction fetch request and determining whether a current physical address translation is valid for the next virtual fetch address in response to its generation, wherein the determination may comprise detecting a change in the virtual page number of the next virtual fetch address relative to a virtual page number of a current virtual fetch address. The method may further comprise activating an ITLB circuit in response to determining that the current physical address translation is not valid for the next virtual fetch address, and performing the instruction fetch using the current physical address translation without activating the ITLB circuit in response to determining that the current physical address translation is valid for said next virtual fetch address.Type: GrantFiled: September 4, 2003Date of Patent: July 11, 2006Assignee: Advanced Micro Devices, Inc.Inventors: Michael G.

Patent number: 7075378Abstract: A high spectral purity microwave oscillator is provided. The Oscillator uses an air-dielectric cavity and employs the known carrier-suppression technique. In one embodiment, the oscillator employs a high-Q cavity to self-sustain an oscillating signal formed by feeding back into its input a power-amplified output signal of the cavity in which residual phase noise in the amplifier stages is suppressed. A bandpass filter selects the cavity mode. FIG. 1 illustrates this embodiment. Another embodiment suppresses the noise of a voltage-controlled oscillator whose frequency and power-amplified output interrogates the cavity mode. FIG. 2 illustrates this embodiment.Type: GrantFiled: July 7, 2004Date of Patent: July 11, 2006Assignee: The United States of America as represented by the Secretary of Commerce, the National Institute of Standards and TechnologyInventors: David A.

Patent number: 7030777Abstract: A system and method for generating remote incursion alerts in response to incursion detected by incursion transmitter units, such as at traffic cones, posts, barricades and signage. Alerts are generated in response to impacts detected at the safety icons within an incursion transmitter (or transceiver) and transmitted to one or more incursion receiver units which annunciate the alert with audio, lights, and or tactile output to warn construction crews of possibly impending danger. The alert signals may be communicated over a wired connection or a wireless communication link. Alert signals wirelessly communicated are preferably repeated by other incursion transmitters which are each coupled to a receiver to form a transceiver, wherein the distance and conditions over which the wireless alert signals may be communicated is extended. The incursion receiver may generate area alerts, or personal alerts, such as comprising the generation of audio, physical outputs, or light signals.Type: GrantFiled: November 5, 2002Date of Patent: April 18, 2006Assignee: Logic Systems, Inc.Inventors: Craig Nelson, Robert E.
