Abstract: Various aspects are disclosed herein for bounding the behavior of a non-privileged virtual machine that interacts with a device by creating a description of the device which indicates to a privileged authority (1) which operations on the device may have system-wide effects and (2) which operations have effects local to the device. The privileged authority may then permit or deny these actions. The privileged authority may also translate these actions into other actions with benign consequences.

Abstract: Systems and methods are provided, whereby partitions may become enlightened and discover the presence of a hypervisor. Several techniques of hypervisor discovery are discussed, such as detecting the presence of virtual processor registers (e.g. model specific registers or special-purpose registers) or the presence of virtual hardware devices. Upon discovery, information (code and/or data) may be injected in a partition by the hypervisor, whereby such injection allows the partition to call the hypervisor. Moreover, the hypervisor may present a versioning mechanism that allows the partition to match up the version of the hypervisor to its virtual devices. Next, once code and/or data is injected, calling conventions are established that allow the partition and the hypervisor to communicate, so that the hypervisor may perform some operations on behalf of the partition.

Abstract: A game interface is presented at a plurality of client devices during an early phase of a synchronized gaming schedule shared among the client devices. An application program residing at each of the client devices generates and presents, during an intermediate phase of the synchronized gaming schedule following the early phase, an individual results summary. Individual results information is received from each client device over the communications network indicating a comparison of one or more puzzle-submissions by a player of that client device to the one or more puzzle-answers of the answer key. The individual results information received from each of the client devices is aggregated to obtain aggregated results information during the intermediate phase. The aggregated results information is transmitted to each of the client devices over the communications network for presentation at the client devices during a late phase of the synchronized gaming schedule.

Abstract: A game interface having multiple game-object locations is constructed by removing a remaining game-object from a pool of game-objects and loading that removed game-object into an empty game-object location for each of the game-object locations. A candidate game interface that is fully loaded with game-objects is compared to a rule set. A candidate game interface is rejected if it violates the rule set. If a candidate game interface does not violate the rule set, the candidate game interface is deployed to a gaming environment as an approved game interface.

Abstract: Word-commonness is identified for each word of a set of words of a language within a corpus of electronic documents. The set of words are sorted according to the word-commonness of each word relative to the other words of the set to obtain a sorted list. The sorted list defines an order of the words of the set that is based, at least in part, on the word-commonness of each word relative to the other words of the set.

Abstract: The present invention provides a horizontally depleted Metal Semiconductor Field Effect Transistor (MESFET). A drain region, a source region, and a channel region are formed in the device layer such that the drain region and the source region are spaced apart from one another and the channel region extends between the drain region and the source region. First and second gate contacts are formed in the device layer on either side of the channel region, and as such, the first and second gate contacts will also reside between opposing portions of the source and drain regions. With this configuration, voltages applied to the first and second gate contacts effectively control vertical depletion regions, which form on either side of the channel region.

Abstract: A pipe coupling with an anchoring arrangement for locking the pipes together axially. The anchoring arrangement comprises a tubular casing, a frusto-conical gripping ring with inwardly projecting gripping teeth and tensioning bolts for tightening the casing about the frusto-conical gripping ring. The frusto-conical gripping ring is formed of a plurality of arcuate segments which overlap to form a complete ring. By forming the gripping ring of segments, the gripping ring is able to adapt to pipes that are not truly circular in cross section and a better grip on the pipe may be achieved than with a single-piece gripping ring.

Abstract: Techniques to share media files through messaging are described. An apparatus may comprise a processor and a memory communicatively coupled to the processor. The memory may store a message application that when executed by the processor is operative to communicate a message and a message attachment comprising a media file at different time intervals using different transports. The message may have a link comprising a reference to a discoverable storage location for the media file. Other embodiments are described and claimed.

Abstract: Various operations are disclosed for improving the operational efficiency of register handling in a virtualized environment. Some infrequently accessed software managed registers are managed lazily when switching contexts between virtual processors. The states of those registers are not saved on exit from a guest or restored on entry to the guest. Rather, guest accesses to those registers are intercepted. For some frequently accessed registers, register states are saved or restored only upon exit from a hypervisor to a different guest that that from which the hypervisor was entered. For enable-flag-gated registers, updates to a physical register value are not made unless the register is enabled. A shadow register cache may be used to speed accesses to some registers. When a shadowed register is modified, the new value is cached as a shadow copy in RAM and subsequent reads of the register are taken from the shadow copy.

Abstract: Embodiments of a Low Dropout (LDO) regulator are provided in which an n-channel Metal Semiconductor Field Effect Transistor (MESFET) is utilized as a pass transistor of the LDO regulator. In one embodiment, the LDO regulator is implemented on an integrated circuit die and includes an n-channel Semiconductor-on-lnsulator (SOI) MESFET pass transistor. A voltage applied to a substrate of the SOI MESFET pass transistor is controlled to configure the LDO regulator in either an ultra-low dropout voltage mode or a high Power Supply Rejection (PSR) mode. In another embodiment, the LDO regulator includes an re-channel MESFET pass transistor and a switch that operates to disconnect the MESFET pass transistor from a supply voltage of the LDO regulator when the LDO regulator is desired to be shut off.

Abstract: Plural guest operating systems run on a computer, where a security kernel enforces a policy of isolation among the guest operating systems. An exclusion vector defines a set of pages that cannot be accessed by direct memory access (DMA) devices. The security kernel enforces an isolation policy by causing certain pages to be excluded from direct access. Thus, device drivers in guest operating systems are permitted to control DMA devices directly without virtualization of those devices, while each guest is prevented from using DMA devices to access pages that the guest is not permitted to access under the policy.
