摘要:
A ring oscillator test circuit, includes an odd number of stages, where each stage includes a load and drive transistor connected in series at a common node. The common node of each stage is electrically connected to the drive transistor gate of the following stage, and the common node of the last stage is connected to the drive transistor gate of the first stage. A first voltage input connects to the drains of all the load transistors. A second voltage input connects to the gates of all of the load transistors. A reference voltage input connects to the sources of all of the drive transistors. At least one of the common nodes connects to a test output.

The invention, in some embodiments, relates to the field of global navigation satellite systems, and more particularly to the field of methods and devices for improving accuracy of position determination by receivers of global navigation satellite systems. Some embodiments of the invention relate to methods for generating a three-dimensional (3-D) representation of an urban area by a receiver of a global navigation satellite system using blocked lines of sight to satellites of the system. Additional embodiments of the invention relate to methods for transmitting a three-dimensional (3-D) representation of an urban area by a receiver of a global navigation satellite system for improving calculation of location by the global navigation satellite system receiver.
摘要:
There is disclosed a system and method for processing wine and/or a containing barrel, while keeping a volume of most of the wine in the barrel. The disclosed system and method can provide reduced mixing of different layers of wine in the barrel. An optional scrubbing mechanism cleans an interior surface of the barrel from encrusted matter, and an optional UV sterilization light source sanitizes an interior surface of the barrel that is alongside a cavity in the barrel empty of wine. In some embodiments a pumping and filtering system preserves non-mixing flow of wine in the barrel while effectively filtering wine optionally without the use of a filter cartridge or other interposing medium.
摘要:
A method of generating a signal being phase-shifted at a predetermined phase-shift division factor relative to a reference signal is disclosed. The method comprises: using the predetermined phase-shift division factor for selecting a modulation amplitude, modulating a control signal at the selected modulation amplitude, and combining the reference signal and the control signal to form the phase-shifted.
摘要:
The invention relates to a method (100) for inspecting a zone, termed the zone of interest, whose characteristics are known at least partially, so as to detect at least one element included in said zone of interest, said method (100) comprising: a first detection (102-108) providing, through a time reversal method, a first signal relating to the position of said element (302) for a first emission point (312), and at least one second detection (110‑116) providing, through a time reversal method, at least one second signal relating to the position of said element (102) for a second emission point (114) different from said first emission point (314). The method furthermore comprises a multiplication (118) of the first detection signal with the second detection signal to provide a third detection signal which is more accurate than the first and the second detection signal. It also relates to a system implementing this method.
