Abstract: Sintering die-attach materials provide a lead-free solution for semiconductor packages with superior electrical, thermal and mechanical performance to prior art alternatives. Wafer-applied sintering materials form a metallurgical bond to both semiconductor die and adherends as well as throughout the die-attach joint and do not remelt at the original process temperature. Application to either one or both sides of the wafer, as well as paste a film application are disclosed.

Abstract: A radiation protection system for protecting medical personnel from radiation being applied from a radiation source to a patient positioned on a table that includes a radiation-shielding wall including, upper shield suspended by a gas spring lift arm, the upper shield consisting of translucent radiation resistance window, with a left and right side of flexible radiation shielding material, that telescopes down on each side of the table to form a complete radiation barrier. The shield is positioned above the table. The shield also has a radiation-shielding flexible interface attached to the radiation shielding window that covers a portion of the patient.

Abstract: An electromagnetic survey method for surveying an area that potentially contains a subterranean hydrocarbon reservoir. The method comprises detecting a detector signal in response to a source electromagnetic signal, resolving the detector signal along at least two orthogonal directions, and comparing phase measurements of the detector signal resolved along these directions to look for a phase separation anomaly indicative of the presence of a buried hydrocarbon layer. The invention also relates to planning a survey using this method, and to analysis of survey data taken using this survey method. The first and second data sets may be obtained concurrently with a single horizontal electric dipole source antenna. The method is also largely independent of a source-detector pair's relative orientation and so provides for good spatial coverage and easy-to-perform surveying.

Abstract: Apparatus for enabling the use of a computer mouse at a sterile surgical site comprises a pouch for the accommodation of the mouse and an inlet sleeve forming an inlet passage into the pouch. The pouch and sleeve are formed of pliable, preferably transparent sterilizable material. When the mouse has been admitted to the pouch via the passage, the sleeve may be separated from the pouch and the open mouth of the latter rolled to form a seal, thereby retaining the mouse within the pouch.

Abstract: This is a device that controls centrifugal force to produce variable linear force in a direction that may be altered at any time by the operator. All moveable parts ride on bearings, and the negative forces that are created by rotating the weighted arms inward are counteracted by other weighted arms rotating outward, or positive forces, so that the device can operate on a relatively small power supply. The device is comprised of a fixed single Main shaft which is attached to the frame. Said shaft has two collars held in place by bearings, thus are independent of said shaft. Each collar has a sprocket attached to it and is controlled by an outside means. One collar is a drive collar that will rotate continuously at a set speed. The second collar is a steering collar which will remain in a fixed position until the operator decides to adjust speed or course. The drive collar has at least 4 Primary arms that extend perpendicular from the Main shaft.

Abstract: The cage comprises a metal support framework and plastic panels that define trays for containing live-poultry. Horizontal floor panels of the trays are domed and slitted to prevent pooling of water. Vertical fence panels are formed as open lattice boxes, combining good containment with good ventilation. Openable doors for the trays have a double-detent camming action, whereby the doors snap to open or snap to closed, whichever is closer. The cage is lifted on/off a truck with a fork lift.

Abstract: A protective cover for removable attachment to an objective lens housing of a draped surgical microscope has a primary, annular retainer of such size as to encircle and engage the lens housing. The retainer has an external frusto-spherical surface and an internal surface capable of seating on and snugly engaging the lens housing. The retainer removably supports a transparent shield for protecting the lenses in the lens housing. A secondary annular retainer encircles the primary retainer and has an internal surface which seats on and is supported by the external surface of the primary retainer. The secondary retainer removably accommodates a second transparent shield forming a closure for the secondary retainer. The second retainer is axially, rotatably, and rockably adjustable relative to the primary retainer for minimizing the transmission of glare to the microscope.
