Abstract: Apparatus for modelling or simulating the dynamics of interacting rigid bodies. In the apparatus, the rigid bodies are represented as convex polyhedra. Contacts between the bodies are modelled as contacts between a face and a vertex or between edges. All other types of contact are reduced to these types. The beginning or end of a contact is determined by means of linear interpolation. The dynamics of the contacts are modelled as convicts between massless rigid surface elements which are connected by massless viscous layers to the objects. The viscous layer connecting a surface element to its object permits the surface element to move either perpendicular to or tangent to the plane of contact. The properties of the viscous layers determine the dynamics of the contacts. In the implementation, the properties are described by means of two systems of springs and dampers, one permitting motion in the perpendicular direction and the other motion in the tangential direction. Parameters of the spring and damper systems may be set as required to model contacts between various kinds of objects.

Granted: 1999-02-16
Abstract: A support beam for a storage rack has a tubular profile, which defines a ledge opening upwardly and inwardly, and which defines a generally flat, indicia-receiving surface facing outwardly and either downwardly or upwardly at an angle from about 20° to about 70° relative to a vertical plane.  Alternatively, the tubular profile may define two such surfaces defining an obtuse angle relative to each other, namely an upper surface at an angle from about 20° to about 45° relative thereto and a lower surface at an angle from about 45° to about 70° relative thereto, or a generally arcuate, indicia-receiving surface having a suitable measurement. The indicia-receiving surface enables a person who is standing, or who is sitting on a lift truck, to have a generally perpendicular line of sight to such surface. The support beam may also be used in combination with a properly positioned fire extinguishing device to extinguish a fire in a supported load.  When the fire extinguisher is activated, the fluid that is discharged impinges off the indicia-receiving surface, which may be inclined or curved, and onto the load.

Title: Apparatus and method employing fast polarization modulation to reduce effects of polarization hole burning and polarization dependent loss
Inventor: HEISMANN FRED LUDWIG
IPC: G02F1/01
Filed: 1994-04-20
Granted: 1998-07-14
Abstract: The effects of polarization dependent hole burning and polarization dependent loss are reduced by modulating the state of polarization (SOP) of an optical signal being launched into an optical transmission path periodically between first and second states of polarization of at least one pair of orthogonal states of polarization. Preferably, the SOP is modulated at a rate that is substantially higher than 1/ ts,  where t s is the anistropic saturation time of the optical amplifier. Ideally, the state of polarization of the launched optical signal should be modulated such that it traces a complete great circle on the Poincare' sphere. In addition, the effects of polarization dependent loss are further reduced by controllably selecting the particular great circle being traced on the Poincare' sphere. In one example, the particular great circle being traced is selected such that a predetermined parameter, for example, the signal to noise ratio, of the optical information signal being received at the remote end of the optical transmission network is maintained at a prescribed value, e.g., a maximum value. In an embodiment of the invention, the great circle is traced at a uniform speed such that the launched optical signal spends equal time intervals in both states of any pair of orthogonal states of polarization on the selected great circle on the Poincare ' sphere. (FIG. 1).

Title: Surface mount solder assembly of leadless integrated circuit packages to substrates
Inventor: DEGANI YINON
IPC: H01L21/48
Filed: 1994-07-12
Granted: 1999-05-18
Abstract: Described are a process for soldering at least one component having solder bumps to a substrate and a process for forming solder bumps on metal pads of an element, such as an IC package or substrate or both. The bumps are formed by stencil printing solder paste deposits on the metal pads, heating the solder paste deposits to reflow temperature of the solder in the solder paste deposits, and allowing the molten solder in each deposit to coalesce and during subsequent cooling solidify forming the bumps on the metal pads. The bumps are formed by conducting the stencil printing through apertures in an ultra-thick stencil, the apertures having trapezoidal crossection in the plane normal to the broad surfaces of the stencil with the top opening being smaller than the bottom opening and with the walls of the aperture sloping at an angle within a range of from 1 to 45 degrees from the vertical, the solder paste having a low tackiness and high metal loading, and the solder paste deposits covering an area which is equal to or exceeds an area of the metal pad in any ratio between 1.5:1 and 5:1. Bumps formed in this manner lead to the formation of reliable solder joints.

Abstract: A data processing system that employs a rechargeable battery and supports a full discharge of the battery and that is not shut down even if a user mistakenly removes a battery while the system is being operated in a full discharge mode, and a power supply apparatus for such a data processing system and a method for using the apparatus. When a data processing system is to be operated in a full discharge mode, an external power source constantly and steadily supplies power to the first electric circuitry, while a battery supplies power to the second electric circuitry until the discharge is completed. The first electric circuitry is designed to include components, such as a CPU and a main memory, that may force the entire system to be shut down when the supply of power is abruptly halted to those components. The second electric circuitry is designed to include components, such as a backlight of a liquid crystal display device, that do never cause the entire system to be shut down even when the power supply to only these components is abruptly terminated. Therefore, when a user mistakenly removes a battery while a full discharge of the battery is in progress, only the power supply to the second electric circuitry is stopped, and the whole system will not be shut down. When the power supply arrangement is so designed that only an external power source supplies power in response to the detection of the removal or the battery, only a backlight is turned off at the moment a battery is removed; and immediately turned on so that the task executed by the CPU 11 will not be abruptly terminated.
