61 results about "Internal conversion" patented technology

Internal conversion is a radioactive decay process wherein an excited nucleus interacts electromagnetically with one of the orbital electrons of the atom. This causes the electron to be emitted (ejected) from the atom. Thus, in an internal conversion process, a high-energy electron is emitted from the radioactive atom, but not from the nucleus. For this reason, the high-speed electrons resulting from internal conversion are not called beta particles, since the latter come from beta decay, where they are newly created in the nuclear decay process.

Voltage Drop Effect On Static Timing Analysis For Multi-Phase Sequential Circuit

In the present invention a method to address voltage drop effect in the path based timing analysis for multi-phase sequential circuit is proposed. In calculating the new delay of the gate along the specified path the fact that stored discrete arrival times with respect to different clock phases at each node is used to determine a set of gates that can have transitions overlapping with that of the said gate. Furthermore, the said set is reduced by the logic verification step. Two step approach is adopted, the first is to evaluate the power currents for the said reduced set of gates by using pre-characterized timing library, then use these currents to calculate new VDD of the said gate along the path and obtain new delay for this gate. Some cell may have several internal transitions, the process of modeling power currents in terms of several triangles is discussed.

Dual-stringing conversion and playing surface separation ring for sports racquet

InactiveUS20070087871A1Strength of frame compromisedIntegrality of compromisedStringed racketsCombined useEngineering
A devise that enables the conversion of any sports racquet, such as a tennis racquet or a squash racquet, from a conventional “single-strung” configuration to a “dual-strung” configuration without altering or making any changes to the racquet frame itself. Whereas all embodiments to date for the dual stringing of a sports racquet utilize a specialized racquet frame specifically designed to accommodate or provide for the two generally parallel planes of crisscross strings that comprise the two playing surfaces, this invention requires no such specialized frame or alteration to the existing frame. The invention consists of an inner conversion ring that is used in conjunction with, or as an accessory to, any conventional racquet frame and permits said conventional frame to be “dual-strung” yielding two playing surfaces of generally parallel planes of crisscross strings. The conversion ring itself can be made of any rigid or semi-rigid material such as wood, plastic, metal, rubber or composite material. It is shaped and sized to fit within the more or less oval frame structure of the racquet head. The thickness of the ring can be varied and determines the separation between the two string playing surfaces. The racquet is then strung twice, using conventional techniques, so that the strings pass over each side of the conversion ring that acts as the separator between the two playing surfaces. Different string tensions and / or different sting types may be used for the playing surface on each side of the separation ring. This permits any ordinary sports racquet to be further tailored to the player's forehand and backhand.
