摘要:
A system and method for handling system management interrupts in a multi-processor computer is disclosed. When the computer enters system management mode, the method uses the registers of each processor to get currently executing opcode to determine what each processor was doing before the interrupt. The method may have to first translate address information to locate the actual physical location of the currently executing opcode. The registers are stored in memory and the contents of the registers can be used to determine if the current processor caused the system management interrupt. If so, then the method now knows which processor caused the interrupt and can handle the interrupt accordingly. If, however, the processor was not the one that caused the interrupt, or if another processor also caused an interrupt, the method then repeats the above steps for the next processor of the multiprocessor system.

An aircraft seat pan assembly to be mounted on an aircraft seat foundation including a pair of spaced side rail supports and a pair of spaced apart cross supports disposed in spanning relating between the side rail supports, the seat pan assembly including a seat panel with a primary surface, a pair of opposite side edges, a front edge, and a rear edge. The side edges and front edge of the seat panel are structured to be secured directly to the side rail supports and a front cross support of the seat foundation in generally planar relation thereto, and a rear edge of the seat panel is structured to be secured to the rear cross support in a generally elevated, spaced apart position there above such that a quantity of a downward spine load exerted on the seat panel will be absorbed at the connection between the rear edge and the rear cross support. Accordingly, the panel will resist the downward spine load thereon to a satisfaction of FAA guidelines with a minimum initial stroking distance between the primary surface of the seat panel and any underlying seat frame portions being maintained.

An attenuated aircraft seat back assembly for use on an aircraft passenger seat of the type which includes a seat back frame with a front side and a rear side, the attenuated assembly comprising a mount assembly structured to be secured at the rear side of the seat back frame, preferably at an upper end thereof, and an impact absorbent, generally rigid material panel fixedly secured thereto. The mount assembly is structured to securely maintain the rigid material panel in a generally parallel orientation relative to the seat back frame, and spaced apart from the seat back frame by a predetermined distance. The rigid material panel, which is sized and configured to shield an upper region of the seat back frame, is substantially lightweight and includes a honeycomb interior core structured and disposed to substantially resist the force of a direct impact thereto, while still yielding sufficiently so that an object impacting the rigid material panel will have a Head Injury Criteria (HIC) value which is acceptable under current Federal Aviation Administration regulations. Preferably, an energy absorbent, resilient material panel is adhered to a front face of the rigid material panel, and together have a combined thickness of generally about two inches, while being spaced apart from the seat back frame in assembled form so as to minimize an overall thickness of the assembly.

A support structure for a membrane comprises a plurality of support members and at least one flange, including: (a) a first set of spoke-like support members that extend generally from at least one flange toward a common hub and that have a distal end joined to at least one flange and a proximal end joined to the common hub; and (b) at least one subsequent set of spoke-like support members that are distributed between circumferentially adjacent pairs of spoke-like support members from the prior sets and that extend generally from at least one flange toward the hub, each having a distal end joined to at least one flange and a proximal end connected to the nearest circumferentially adjacent pair of spoke-like support members from the prior sets via a pair of approximately straight anchoring support members which join together and form an angular joint at or near said proximal end, with the vertex of said angular joint pointing generally away from the hub.

An improved radiation window comprises a film permeable to radiation disposed on a support structure. The support structure comprises a primary transmissive area comprising a plurality of support members defining a plurality of apertures for radiation to pass through; a flange disposed around the periphery of the primary transmissive area having generally greater mechanical rigidity than the primary transmissive area; and a transition region disposed between, and contiguous with, the primary transmissive area and the flange; the transition region having generally greater mechanical rigidity than the primary transmissive area and generally lesser mechanical rigidity than the flange, thereby providing an intermediate rigidity transition between the dissimilar rigidities of the primary transmissive area and the flange. A radiation detection system comprises a sensor configured to detect radiation, disposed behind such an improved radiation window.
摘要:
A pool cue shaft assembly includes a thermoplastic support body extending along a shaft axis from a tip end to a collar end. The support body defines at least three fin members extending radially from a geometric center of the support body. Spaces between the radially extending fin members define at least three longitudinal grooves. At least three inlay members are coupled to the thermoplastic support body. Each inlay member is disposed within a respective longitudinal groove and extends from the tip end to the collar end.
