Abstract: A request is made by a system in a first logical partition, within a logically partitioned data processing system, to dynamically change the I/O configuration of the host system in a way that affects a system in a second logical partition. The hypervisor intercepts the request, ensures the serialization of such dynamic I/O requests, and allows dynamic reconfiguration to proceed. Subsequently, the hypervisor determines the effect of the reconfiguration on the second partition, and notifies the second partition of the change.

Abstract: The invention discloses a non-contact way to provide electrical power and two-way digital communications between a host computer and its peripheral modules, such as IC memory cards, modems, and A/D converters. A special magnetic core is employed to provide efficient transfer of both large amounts of electrical power and high speed digital communications through transformer action. Peripheral modules requiring different power supply voltages or different data voltage levels can be accommodated and intermixed with modules of other types in the same host system. The mechanical design of the connector includes detent structure to align the assembly in three dimensions, both upon mating, and under mechanical environmental stress conditions during operation. The magnetic core has both power supply and data windings; the data winding has sections of opposite polarity so that the power supply signal imposed on the data winding cancels itself.

Abstract: A CPU interface recognizing a large very number of I/O interruption queues in a logically partitioned data processing system. Different partitions may contain different guest operating systems. The CPU interface controls how plural CPUs respond to I/O interruptions put on numerous hardware-controlled queues. A host hypervisor program dispatches the guest operating systems. The guests use the I/O interruptions in controlling the dispatching of their programs on the CPUs in a system. The invention allows the number of guest partitions in the system to exceed the number of I/O interruption subclasses (ISCs) architected in the system, and enables the dispatching controls of each guest operating system to be sensitive to different priorities for plural programs operating under a respective guest. The invention provides CPU controls that support alerting the host to enabled I/O interruptions, and provides CPU controlled pass-through for enabling direct guest handling of the guests I/O interruptions.

Abstract: The embodiment discloses a method and means for partitioning the resources in a data processing system into a plurality of logical partitions. Host control code may be embodied in programming, microcode, or by special hardware to enable highly efficient operation of a plurality of preferred guest programming systems in the different partitions of the system. The main storage, expanded storage, the channel, and subchannel resources of a system are assigned to the different logical partitions in the system to enable a plurality of preferred guest programming systems to run simultaneously in the different partitions. This invention automatically relocates the absolute addresses of the I/O channel and subchannel resources in the system to their assigned partitions. Also the absolute and virtual addresses of the different guest programming systems are relocated into, as well as page addresses for any expanded storage, their assigned partitions.

Abstract: A low profile opto-device panel assembly suitable for use in an input detection apparatus used as an input device in conjunction with a visual display is disclosed. Arrays of light emitting devices and light detecting devices are juxtaposed along the internal edge of a peripheral frame printed circuit board to reduce the overall height of the panel assembly. Alignment housings surrounding each of the arrays of opto-devices are attached to the printed circuit board and extend inwardly of the sides of the peripheral frame printed circuit board. The opto-devices disposed in the alignment housings along the internal edge of the printed circuit boards are mechanically and electrically interconnected to the printed circuit board by bent leads which extend along the upper surface of the printed circuit board and into conventional printed circuit board holes.

Abstract: A frame assembly for mounting a sunroof panel in the roof of a vehicle includes top and bottom portions respectively disposed above and below the roof and which are secured together with the roof tightly sandwiched therebetween. The bottom frame portion includes a lateral channel-like extension for supporting a weatherstrip which engages and supports the sunroof panel. The top and bottom frame portions include a first set of opposing flanges between which the vehicle's roof is tightly sandwiched and a second set of opposing flanges between which a portion of the weatherstrip is trapped, thereby mounting the weatherstrip on the frame and creating a positive seal around the entire perimeter of the frame which prevents moisture from entering the vehicle between the weatherstrip and the frame. The frame portions are drawn together against the roof by screws extending through the bottom frame portion into a continuous rib in the top frame portion which is received within a channel in the bottom frame portion.

Abstract: The embodiments enable address translations for a virtual machine in the TLB (translation lookaside buffer) of a CPU to be retained from exiting a SIE (start interpretive execution) instruction to the next SIE entry to interpretive execution for the same guest (virtual machine CPU). Conditions are defined which determine when guest TLB entries must be invalidated. These conditions require invalidation of guest TLB entries only within and on entry to interpretive execution. A single invalidation of guest TLB entries on entry to interpretive execution is required for any number of conditions recognized while a CPU is not in interpretive execution state. For a guest in a virtual multi-processor (MP) machine, an interlock is provided to allow the use of guest virtual addresses by host instruction simulation and the need for guest TLB invalidation is broadcast to all other real CPUs in a real MP system so that all guest TLBs on all real CPUs can be invalidated to maintain integrity.

Abstract: A touch entry system employing arrays of emitter and detector opto devices located around the periphery of an irradiated field detects intrusion of an opaque element such as a stylus within the field. The detector analog output is converted to a digital signal for input into a microprocessor. Digital signals input into the microprocessor can vary due to inconsistencies in conventional opto devices. A programmable amplifier responsive to the microprocessors preconditions the analog signals prior to analog to digital conversion to bring all digital signals corresponding to the unblocked emitter beam condition within a normalized range before input into the microprocessor.

Abstract: A method for controlling both shared and exclusive access for a resource in a multiprocessor system wherein a first-in/first-out queue is formed for tasks suspended while awaiting access and wherein access to the resource provides that control of access required for manipulation of the first-in/first-out queue which is not provided by the atomic nature of compare (double) and swap. Each member of the queue has indicators of the access it requested and of the next most recently enqueued member which has a corresponding indicator. A lockword is established having two parts, a lock flag indicating the status of the resource, whether available, under shared ownership or under exclusive ownership and a lock pointer pointing to the most recently enqueued task. In requesting or releasing access, an initial guess is made as to the value of the lockword and a projected lockword is calculated based on the guess.

Abstract: An air screen for vehicle sunroofs extends between the leading edges of an open sunroof panel and the vehicle's roof to regulate intake air flow and prevent potentially dangerous projectiles from being carried into the vehicle's interior along with the air flow. The air screen is formed from flexible plastic material and deflects into a storage position when the sunroof panel is pivoted from an open scoop position to a closed position. The air screen may be secured to either the sunroof panel or the roof and consists of two halves slidable relative to each other so as to permit regulation of the air flow therethrough. The air screen also functions as an air deflector to prevent wind buffeting effects when the panel is completely removed from the roof.

Abstract: An air deflection assembly particularly adapted for use with vehicle sunroofs includes a substantially planar, air deflecting member pivotally mounted in spaced relationship to a leading edge of an opening in the vehicle's roof. A support comprising a pair of spaced, parallel rods has the opposite ends thereof respectively pivotally connected to the deflection member and a frame surrounding the periphery of the sunroof opening to define a pair of transversely extending pivot axes which permit adjustment of both the elevation and inclination of the deflection member. In an elevated position above the vehicle's roof, the deflection member functions to prevent wind buffeting noise. The inclination of the deflection member may be readily adjusted to deflect air passing over the sunroof into the interior of the vehicle.

Abstract: A removable sunroof panel adapted to be mounted in overlying relationship in an opening in the roof of a vehicle includes front and rear mounting assemblies which allow either or both the front and rear of the panel to be held in an open position above the vehicle's roof. Each of the mounting assemblies includes a lever handle pivotally connected to the sunroof panel and a latching assembly for receiving and locking the lever handle in a plurality of positions. A frame molding mounted in the sunroof opening includes a first section overlying the roof, and second and third sections below the roof defining a channel for receiving a resilient seal against which the roof panel seats; the second and third sections include a pair of opposed grooves for captivating a pair of ribs in the seal to retain the seal in the channel.

Abstract: The snow ski braking device comprises a bracket adapted to be mounted on the top face of the ski and having a pair of pivoted brake members straddling each side of the ski and biased to pivot downwardly to penetrate into the skiing surface when forward motion of the ski is arrested. Each brake member has a vertically oriented lower blade and a top horizontal paddle which cooperate to provide the desired braking action without interferring with the normally intended use of the ski.

Abstract: A detachable sunroof panel is adapted to be secured within an opening formed in the roof of an automobile. The securement is carried out by a system of latches, all of which act on the panel to compress a resilient seal member extending about the periphery of the opening between the roof panel and a lip portion formed on a frame secured within the opening. The latch system includes a latch-handle mechanism located at the rear edge of the panel comprised of an overcenter linkage which may also be detached for removal of the sunroof panel. The latch-handle may be moved to a latched position, or to a second vent position allowing movement of the rear portion of the sunroof panel upwardly to create a vent opening. The latch system further includes a pair of latch-hinges located along the front edge of the panel, each of which also comprise a releasable overcenter linkage adapted to compress the peripheral seal in the secured or locked position and upon release allow detachment and removal of the sunroof panel.

Abstract: A character generator system suitable for creating a character display on the screen of a standard TV receiver is disclosed. The character generator system includes a sync generator which generates timing and synchronizing signals that create a 263 line, non-interlaced, roster. The character generator system also includes a character generator adapted to receive binary signals that define the character display. The character generator is timed and synchronized by the sync generator so as to create a charater video signal suitable for creating the character display as the screen of the TV receiver is scanned. Color is added to the character video signal by a chroma generator in a manner such that the background is in one color and characters are in another color. The 263 line raster (non-interlaced) results in a color display without color fringing.
