Abstract: The embodiments of the invention provide a method, computer program product, etc. for risk-modulated proactive data migration for maximizing utility. More specifically, a method of planning data migration for maximizing utility of a storage infrastructure that is running and actively serving at least one application includes selecting a plurality of potential data items for migration and selecting a plurality of potential migration destinations to which the potential data items can be moved. Moreover, the method selects a plurality of potential migration speeds at which the potential data items can be moved and selects a plurality of potential migration times at which the potential data items can be moved to the potential data migration destinations. The selecting of the plurality of potential migration speeds selects a migration speed below a threshold speed, wherein the threshold speed defines a maximum system utility loss permitted.

Abstract: An efficient method of amplifying a digital signal with reduced electromagnetic interference is disclosed. The invention applies an average amplitude detector to the input signal to control the clock frequency of a pseudo-random number generator so that the clock signal decreases when the average amplitude of the signal increases. The input signal and the pseudo-random number generator are compared to generate a control signal for a switching power amplifier followed by a low-pass filter. When the average amplitude of the input signal falls below a pre-determine threshold, the switching amplifier is placed in a sleep mode.

Abstract: A reusable tamper-evident envelope includes a first substrate, a second substrate superimposed on the first substrate, at least one auxiliary substrate superimposed on and joined along one edge to the second substrate, and at least one seal along all but one edge joining the first substrate to the second substrate. Each auxiliary substrate is spaced a user-defined distance from the top edge of the first substrate. A perforation line, extending from the left side to the right side of both the first substrate and second substrates facilitate removal of a portion of the respective substrates. After an item is placed into the envelope, the user-activated seal along the remaining edge joins the first substrate to the second substrate. Subsequent uses are possible by removing portions of the first substrate and second substrate along the perforation lines and activating the auxiliary user-activated seal along the auxiliary substrate joining the first substrate to the second substrate.

Abstract: A novel single frequency repeater is disclosed that eliminates the problems of feedback and concurrent oscillation. The single frequency repeater of the present invention comprises a backplane, a first antenna, a filter, an amplifier, a power supply, a switch, and a second antenna. The first antenna, filter, amplifier, power supply, and switch are mounted to one side of the backplane. Preferably, the backplane is electrically grounded. The second antenna is mounted on the second side of the backplane, in an orthogonal direction to the first antenna on the first side of the backplane. By placing the first antenna in the back lobe of the second antenna, separating the first antenna and the second antenna with the grounded backplane, and mounting the second antenna in an orthogonal orientation to the first antenna, problems with feedback and concurrent oscillation have been overcome.

Abstract: The present invention is a reliable method of electroless-plating integrated circuit die that achieves high yield. Die are attached to a holder using a polyimide adhesive to eliminate voltage differences on bond pads which would otherwise interfere with the plating. The die are aggressively cleaned using multiple cleaning solutions, one heated to a user-defined temperature. Each cleaning is followed by an aggressive rinse in de-ionized water. Die are immersed into multiple metal solutions at user-definable temperatures. Each immersion is followed by an aggressive rinse in de-ionized water, one with heated de-ionized water.

Abstract: A thin, flexible microelectronic assembly using thinned die (5-10 microns and lower) produced by growing a 1 ?m-10 ?m silicon epitaxial (Epi) layer on an oxidized silicon carrier. The integrated circuit process takes place in the standard manner in the Epi layer. The oxide layer and the silicon carrier serve as the backside handle. Once processed, the wafer can be bumped and singulated just like a normal chip without the need for the extra handle attachment processes or the backside thinning operation. Once the integrated circuits are flipped and solder reflowed to a substrate, the handle can be removed by etching the oxide. In one assembly embodiment, wells are etched in the flexible circuit board material to allow the interconnect to be recessed below the circuit board surface. An adhesive can then be placed on the board surface, locking the die to the flexible substrate. Alternatively, a nanowire interposer can be sandwiched between a bumped multilayer substrate and a bumped thin die.

Abstract: Method of making an integrated passive, such as a high quality decoupling capacitor, includes providing a first temporary support, a silicon capacitor wafer, and providing an oxide layer and a conductive layer on it. Then, a second temporary support, such as a handle wafer, may be attached to the capacitor wafer (i.e., to the oxide layer on it) by an adhesive bond. The capacitor wafer may then be destructively removed. A second conductive layer is then provided on an exposed backside of the oxide layer. The addition of a second electrode on the second conductive layer yields the desired high quality capacitor. Further processing steps, such as solder bumping, may be carried out while the capacitor wafer is still attached to the handle wafer. When the desired processing steps are complete, the handle wafer is removed, and the relatively thin high quality integrated capacitor wafer results.

The amplifier is a differential type, which outputs either a positive voltage or a zero voltage depending upon the majority of the inputs.

Abstract: The present invention is a device for and method of detecting voice activity. First, the AM envelope of a segment of a signal of interest is determined. Next, the number of times the AM envelope crosses a user-definable threshold is determined. If there are no crossings, the segment is identified as non-speech. next, the number of points on the AM envelope within a user-definable range is determined. If there are less than a user-definable number of points within the range, the segment is identified as non-speech. Next, the mean, variance, and power ratio of the normalized spectral content of the AM envelope is found and compared to the same for known speech and non-speech. The segment is identified as being of the same type as the known speech or non-speech to which it most closely compares. These steps are repreated for each signal segment of interest.
