摘要： A leadframe has a die pad area and an outer layer of a first metal having a first oxidation potential. The leadframe is placed in contact with a solution containing a second metal having a second oxidation potential, the second oxidation potential being more negative than the first oxidation potential. Radiation energy is then applied to the die pad area of the leadframe contacted with the solution to cause a local increase in temperature of the leadframe. As a result of the temperature increase, a layer of said second metal is selectively provided at the die pad area of the leadframe by a galvanic displacement reaction. An oxidation of the outer layer of the leadframe is then performed to provide an enhancing layer which counters device package delamination.

摘要： A method and apparatus for selectively connecting a first fluid communication region to a further fluid communication region are disclosed. The apparatus comprises an elongate housing, locatable in a wellbore, comprising a first end portion associated with a first fluid communication region; a sheath member axially slidable within the housing and biased towards the first end portion via at least one biasing element; and an elongate shuttle member axially slidable within the housing and slidably locatable in a sealed relationship or non-sealed relationship with the sheath member; wherein the biasing element provides a predetermined biasing force that determines a threshold pressure which must be exceeded by a fluid pressure in the first fluid communication region to permit axial movement of the sheath member away from the first fluid communication region or towards a further fluid communication region.

摘要： A processing system includes a communication system and a processing core configured to generate write requests. A circuit has associated a slave interface circuit configured to manage an address sub-range and selectively forward write requests addressed to a given address. Configuration data specifies whether the given address is protected/unprotected and locked/unlocked. In response to a received write request, address and data are extracted and a determination based on the configuration data is made as to whether the extracted address is protected/unprotected, and locked/unlocked. When the extracted address is unprotected or unlocked, the slave interface forwards the write request. When the extracted address is protected and locked, the slave interface generates an unlock signal in response to a comparison of the extracted address with the extracted data, with the unlock signal being asserted when the extracted data satisfy a predetermined rule with respect to the extracted address.

摘要： A microelectromechanical system (MEMS) gyroscope includes a driving mass and a driving circuit that operates to drive the driving mass in a mechanical oscillation at a resonant drive frequency. An oscillator generates a system clock that is independent of and asynchronous to the resonant drive frequency. A clock generator circuit outputs a first clock and a second clock that are derived from the system clock. The drive loop of the driving circuit including an analog-to-digital converter (ADC) circuit that is clocked by the first clock and a digital signal processing (DSP) circuit that is clocked by the second clock.

摘要： A cell includes a Z2-FET-type structure that is formed with two front gates extending over an intermediate region between an anode region and a cathode region. The individual front gates of the two front gates are spaced apart by a distance that is shorter than 40% of a width of each individual front gate.

摘要： A first multiplier multiplies a first input with a first coefficient and a first adder sums an output of the first multiplier and a second input to generate a first output. A second multiplier multiplies a third input with a second coefficient, a third multiplier multiplies a fourth input with a third coefficient, and a second adder sums outputs of the second and third multipliers to generate a second output. The second and third inputs are derived from the first output and the first and fourth inputs are derived from the second output. The first and second outputs generate digital values for first and second digital sinusoids, respectively.

摘要： Shelf-stabilized H2S scavengers and methods for preparing such shelf-stabilized H2S scavengers. In one aspect, a stabilized hydrogen sulfide scavenger configured for storage at an elevated temperature includes a base scavenger, free formaldehyde, and a stabilizing alcohol. In another aspect, a method of preparing the stabilized hydrogen sulfide scavenger includes the steps of providing a quantity of base scavenger; providing a quantity of free formaldehyde; and adding a quantity of stabilizing alcohol, wherein the quantity of stabilizing alcohol is determined as a function of the provided quantity of free formaldehyde. In yet another aspect, the stabilized scavenger includes about 25 wt. % base scavenger, wherein the base scavenger is an amine-aldehyde condensate; about 15 wt. % free formaldehyde; and between about 10 wt. % and about 25 wt. % stabilizing alcohol.
