Abstract: Electronic devices having at least two components with mating contact pads are provided with high-aspect-ratio solder joints between the mating pads. These joints ar formed by placing a composite solder medium containing solder wires in an electrically insulating matrix such that at least two solder wires are in contact with the mating pads, and fusing the wires to the pads. The insulating matrix with remainder of solder wires is then optionally removed from between the said at least two components. The composite solder medium is formed by preparing an elongated body of solder wires in an insulating matrix and cutting off slices of the composite solder medium, the solder wires having a high-aspect-ratio of length to their diameter. Alternatively sheets of the composite solder medium are prepared by magnetically aligning solder coated magnetic particles into columns arranged transverse of an insulating matrix and heating sufficiently to fuse the solder in each column into a continuously conducting solder path.

Abstract: The present invention is a method for integrating a file system with a RAID array (1030) that exports precise information about the arrangement of data blocks in the RAID subsystem (1030). The system uses explicit knowledge of the underlying RAID disk layout to schedule disk allocation. The present invention uses separate current-write location (CWL) pointers for each disk (1022) in the disk array (1030) where the pointers simply advance through disks (1022) as writes occur. The algorithm used has two primary goals. The first goal is to keep the CWL pointers as close together as possible, thereby improving RAID (1030) efficiency by writing to multiple blocks in the stripe simultaneously. The second goal is to allocate adjacent locks of a file on the same disk (1022), thereby improving read back performance. The first goal is satisfied by always writing on the disk (1022) with the lowest CWL pointer. For the second goal, another disk (1024) is chosen only when the algorithm starts allocating space for a new file, or when it has allocated N blocks on the same disk (1022) for a single file. The result is that CWL pointers are never more than N blocks apart on different disks (1024), and large files have N consecutive blocks on the same disk (1022).

Title: Linear low-noise mixer
Inventor: KHOURY GEORGE
IPC: H03D7/14
Filed: 1996-06-19
Granted: 2000-11-28
Abstract: A tree mixer includes a first differential pair of transistors which divide current from a first current source between the transistors in dependence upon a first differential input signal supplied to first input terminals. Two second differential pairs of transistors have controlled paths which conduct current, divided between the transistors of the differential pair in dependence upon a second differential input signal supplied to second input terminals, dependent upon current passed by a respective transistor of the first pair of transistors, to produce a product signal at output terminals. One or more second current sources provide for the total current passed by the first pair of transistors to be greater than the total current passed by the two second pairs of transistors, for improved linearity without increasing noise. A quadrature phase modulator can include two such mixers with common output circuitry.

Title: Radio frequency and electrostatic discharge insensitive electro-explosive devices having non-linear resistances
Inventor: BAGINSKI THOMAS A
IPC: F42B3/12
Filed: 1996-08-16
Granted: 2001-12-11
Abstract: An electro-explosive device has two serpentine resistors fabricated on a thermally conductive substrate with the resistors being interconnected by a central bridge element.  The resistance of the bridge element is much lower than that of the serpentine resistors and the serpentine resistors have a much larger surface area to volume ratio.  A layer of zirconium is placed on the bridge element and explodes into a plasma along with the bridge element in order to ignite a pyrotechnic compound.          The resistance of the bridge element increases with temperature whereby the bridge element receives more of the energy from the applied signal as the temperature increases.  The EED is insensitive to coupled RF energy and to an electrostatic discharge since most of the energy from these stray signals is directed to the serpentine resistors and not to the bridge element.  In another embodiment, two of the resistors are metal-oxide phase variable resistances and a third resistor is formed from a bowtie-shaped layer of zirconium.  The resistances through the metal-oxide phase layers decrease with signal intensity whereby the zirconium can receive most of the energy from a high intensity firing signal.  A shunting element, which may be placed across an EED, has a bowtie-shaped conductive layer formed on a substrate.  The conductive layer explodes in a plasma above a certain signal intensity.  The shunting element may comprise another type of device, such as a diode, capacitor, etc.

Abstract: In known devices for testing vehicle shock absorbers, the tires, which have a dampening effect, are not taken into account, so that the measurement results may be falsified by up to about 30 %, depending on the tire pressure. In addition, when the wheels are mounted on the vehicle, no shock absorber characteristic curve may be measured, only individual values. In the disclosed device, the actuating variable "tire" is eliminated by a regulation process that consists in normalising the resonance amplitude, a considerably more accurate measurement being thus obtained. In addition, the spring constant of the wheel suspension is determined before actually testing the shock absorbers, allowing defective springs to be detected. Finally, car body oscillations may also be determined, causing an additional precision gain. For the first time it becomes possible to determine a shock absorber characteristic curve without having to dismount the shock absorbers.

Granted: 2001-10-09
Abstract: A processor (100, 500) that executes applications (99) which require access to time slots of a time-division multiplexed (TDM) communications medium (110) uses spare processing capacity and/or spare hardware of the processor to interface to the TDM medium and to implement a time-slot interchange (TSI) function in a simple and low-cost manner. The processor has a control store (104, 300, 504, 604) that stores a bit map of the time slots of the TDM medium. The bit map is either examined by the processor during each time slot (FIG. 2) to determine, or is used by external circuitry (301, 302) or spare internal circuitry (511) of the processor to generate interrupts (406) or DMA requests that indicate to the processor or to a host interface (510) of the processor, which time slots to access. The processor has a read buffer (105, 505) and a write buffer (106, 506) for effecting data transfers between the TDM medium and the applications. The applications have random access to the buffers, thereby effecting a time-slot-interchange function.
