Abstract: A computer has instruction pipeline circuitry capable of executing two instruction set architectures (ISA's). A binary translator translates at least a selected portion of a computer program from a lower-performance one of the ISA's to a higher-performance one of the ISA's. Hardware initiates a query when about to execute a program region coded in the lower-performance ISA, to determine whether a higher-performance translation exists. If so, the about-to-be-executed instruction is aborted, and control transfers to the higher-performance translation. After execution of the higher-performance translation, execution of the lower-performance region is reestablished at a point downstream from the aborted instruction, in a context logically equivalent to that which would have prevailed had the code of the lower-performance region been allowed to proceed.

Abstract: A method and wireless communication system for transferring management information. The system includes at least one access point (AP) including a first management entity and a second management entity, and at least one wireless transmit/receive unit (WTRU) including a third management entity and a fourth management entity. The AP transmits a management information base (MIB) information request action frame including a category field and an action details field to the WTRU. In response to receiving the information request action frame, the WTRU determines whether or not to provide management information to the AP. When the WTRU provides management information to the AP, the WTRU compiles management information stored in a MIB located in the WTRU and transmits a MIB information report action frame to the AP. The MIB lists a plurality of tables containing information associated with radio resource management (RRM) and at least one table containing physical layer measurements.

Radial loads acting on the timing gear are transmitted from the stator to the rotor and into the outer camshaft. The drive adapter includes an open cylindrical body having first and second ends. The first end includes a slot or recesses in which a timing feature of the cover engages. The second end has a keyed portion configured to matingly engage a corresponding portion of the inner camshaft.
Abstract: A wireless transmit/receive unit (WTRU) reports a buffer status as part of scheduling information for enhanced dedicated channel (E-DCH) transmissions. For reporting the buffer status, the WTRU calculates a total amount of data available across all logical channels for which reporting is requested by a radio resource control (RRC) entity. The total amount of data includes an amount of data that is available for transmission and retransmission at a radio link control (RLC) entity and an amount of data that is available for transmission in a medium access control for enhanced dedicated channel (MAC-i/is) segmentation entity in case that a MAC-i/is entity is configured. The WTRU sends scheduling information including a total E-DCH buffer status (TEBS) field that is set based on the total amount of data.

Abstract: A paintball marker has an inline cylinder that includes a gas governor that reduces gas flow from a compressed gas source to a valve area when the bolt is in a firing position; this increases efficiency in the marker because only the required air is used to fire the paintball. This bolt operates independent of the valve pin, which increases cycle speed and enables the governor to open and close at an optimum time in the firing cycle. Further, when the bolt/piston is recocking, the gap between the valve pin and governor valve pin enables low pressure gas driving the piston to start pressurizing the cylinder and driving the piston rearwards without resistance from the high pressure gas. The marker also allows a user to remove the inline cylinder without tools, and provides a convenient carrying handle for holding the paintball marker, which is commonly called a “snatch grip.

Abstract: A wireless transmit/receive unit (WTRU) communicates in a system which includes plural network protocols. The WTRU includes a circuit configured to make an initial communication request. A communication circuit establishes a communication link in response to the initial communication request in a first direction of communication and a second direction of communication. Circuitry determines a protocol preference for the first direction of communication and to establish communication in the first direction according to the protocol preference separately from communication in the second direction of communication. Circuitry determines a protocol preference for the second direction of communication and to establish communication in the second direction according to the protocol preference separately from communication in the first direction of communication.
Abstract: A criterion for biasing a binary decision requiring an unequal protection which utilizes a measured signal to interference ratio (SIR). The SIR may be derived from a determination of channel estimation. The SIR is compared against a threshold, the threshold being selected to bias the decision toward a not acknowledge (NACK) as opposed to an acknowledge (ACK) determination. The technique is advantageous for providing biased binary decisions for high speed downlink packets (HSDP) but may be utilized for both uplink and downlink applications.

Abstract: A method and device may be used to produce a received interference value in wireless communications. A wireless transmit/receive unit comprising a radio frequency signal measurement device may be configured to produce a value indicating a radio frequency signal, noise and interference received power. An average noise plus interference measuring device may be configured to produce a value indicating a measured average noise plus interference metric. A received signal to noise indication calculation device may be configured to calculate a received signal to noise indicator from the value indicating a radio frequency signal, noise and interference received power and the value may indicate a measured average noise plus interference metric.
Abstract: The object is to provide a uniform impression of noise for an entire image signal by performing grayscale conversion and noise reduction in a balanced manner. The signal processing unit performs first signal conversion on an image signal from an image-acquisition device and transfers the processed image signal to a correction-coefficient calculation unit. The correction-coefficient calculation unit calculates, on the basis of the image signal from the signal processing unit, an area correction coefficient for each area used for grayscale conversion of each area. A noise reducing unit uses the area correction coefficients calculated by the correction-coefficient calculation unit to perform noise reduction on the image signal from the image-acquisition device and transfers the processed signal to the signal processing unit.
Abstract: An apparatus and method is provided for dynamic range power control of a wireless downlink communication signal, such that target signal quality adjustments are held temporarily when it is apparent that transmit power control commands will not produce the desired response at the transmitting station. Comparisons of measured received signals to thresholds are performed to determine whether the transmitting station has either reached the maximum or minimum transmit power, in which case the target signal quality adjustment is controlled accordingly. When normal transmit power is detected, the target signal quality adjustments are allowed to resume as usual.
Abstract: An interferometer for optically measuring an object (10), including a light source (1), at least one beam splitter (2) and at least one detector (12a, 12b), with the beam splitter being arranged in the beam path of the light source such that a light beam created by the light source is split into a working beam (3) and a reference beam (4). The interferometer is embodied such that the working beam impinges on the object (10) to be measured and the working beam is at least partially reflected by the object and interfered with the reference beam on the detector (12a, 12b).
Abstract: A Third Generation Partnership Project (3GPP) media independent handover (MIH) service access point (SAP) is configured to provide MIH event services, (e.g., IEEE 802.21 event services), by mapping service primitives to the MIH event services. The service primitives may be 3GPP service primitives which originate from at least one of a radio resources (RR) layer, a logical link control (LLC) layer, a general packet radio service (GPRS) mobility management (GMM) layer, a session management (SM) layer, a non-access stratum (NAS), an access stratum (AS) and an evolved universal terrestrial radio access (E-UTRA)/evolved core network (E-CORE) system. The event services may include a link parameter change event service, a link up event service, a link going down event service, a link down event service, a handover complete event service and a link detected event service.
Abstract: A method implemented in a wireless communication system including a wireless transmit/receive unit (WTRU), a Node-B and a radio network controller (RNC) for quantizing multiplexed data allowed by grants to closely match a selected enhanced uplink transport format combination (E-TFC) transport block size is disclosed. The amount of scheduled and non-scheduled data allowed to be transmitted is quantized so that the amount of data multiplexed into an enhanced uplink (EU) medium access control (MAC-e) protocol data unit (PDU) more closely matches the selected E-TFC transport block size. In an embodiment, the amount of buffered data allowed to be multiplexed by at least one grant, (a serving grant and/or a non-serving grant), is quantized so that the sum of scheduled and non-scheduled data including MAC header and control information multiplexed into a MAC-e PDU more closely matches the selected E-TFC transport block size.
Abstract: A data processing system ciphers and transfers data between a first memory unit and a second memory unit, such as, for example, between a share memory architecture (SMA) static random access memory (SRAM) and a double data rate (DDR) synchronous dynamic random access memory (SDRAM). The system includes a ciphering engine and a data-mover controller. The data-mover controller includes at least one register having a field that specifies whether or not the transferred data should be ciphered. If the field specifies that the transferred data should be ciphered, the field also specifies the type of ciphering that is to be performed, such as a third generation partnership project (3GPP) standardized confidentially cipher algorithm “f8” or integrity cipher algorithm “f9”.
