A frequency shift Δf obtained by an FM-AFM can be expressed by a simple linear coupling of a ΔfLR derived from a long-range interaction force and a ΔfSR derived from a short-range interaction force. Given this factor, a Δf curve on an atomic defect and a Δf curve on a target atom on the sample surface are each measured for only a relatively short range scale (S1 and S2), and a difference Δf curve of those two curves is obtained (S3). Since the difference Δf curve is derived only from a short-range interaction force, a known conversion operation is applied to this curve obtain an F curve which illustrates the relationship between the force and the distance Z, and then the short-range interaction force on the target atom is obtained from the F curve (S4). Since the range scale in measuring the Δf curve can be narrowed, the measurement time can be shortened, and since the conversion from the Δf curve into F curve is required only once, the computational time can also be shortened. Consequently, in obtaining the short-range interaction force which acts between the atom on the sample surface and the probe, the time required for the Δf curve's measurement and the computational time are shortened, which leads to accuracy improvement and throughput enhancement.

A hash key is generated based on an information object and a lookup operation is performed in a hash table based on the hash key. A determination is made whether an entry in the hash table at an index corresponding to the hash key identifies a labelset for the information object. A labelset, identifying a sensitivity of the information object, is stored in the entry at the index corresponding to the hash key for the information object if a labelset for the information object is not identified in the entry in the hash table. Information flows involving the information object are authorized based on a lookup of the labelset associated with the information object in the hash table. The hash table may be a multidimensional hash table.
One embodiment of the present invention provides a system for executing a command on a computer system. During operation, the system receives a signed command from a first quorum member at a security manager, wherein one or more quorum members must accept the command before the command is executed. Along with the command is data indicating which additional quorum members will be participating in a session, and which quorum persona they wish to invoke for the session. After verifying the signature, the system sends the command to a second quorum member, wherein the command is verified, or authenticated as originating from the first quorum member. Next, the system receives a signed response from the second quorum member, wherein the response indicates whether the second quorum member accepts or rejects the command. If the second quorum member accepts the command, the system sends the command to a native client which executes the command.

A client-side handheld device requests a server to convert server-side documents into a compression format prior to transmission of said documents to the client. The server retrieves and converts the requested documents to a raster image that is then compressed according to attributes based on information received from the client device in the initial document request. Instead of having to manipulate multiple formats which the original documents are in and supported by the server, the client-side device is preferably optimized in hardware and/or software to support and otherwise take advantage of the requested compression format. The compressed document is then delivered to the client device, in whole or in part, selectively or progressively over time per individual requests prior to displaying the received data to the end-user. Depending on the requested delivery mode, server-side documents are preferably compressed using wavelet compression methods, such as the JPEG 2000 standard, known in the arts. Through such a compression format, documents of sizes (in total bytes) exceeding one or more Megabytes can be compressed down to as small as 30 kilobytes or less.

The method accepts microprocessor instructions with consecutive operations, including a conditional branch operation with an associated first branch address. A speculative global history record (SGHR) of conditional branch resolutions and predictions is accessed and hashed with the first branch address, creating a first hash result.

The microprocessor copies the contents of a current CRS to another CRS and designates the other CRS as the current CRS, if the state exists. The microprocessor pushes the address of the next sequential instruction following the call instruction onto the current CRS and fetches an instruction at the call instruction target address if the instruction is a call instruction. The microprocessor pops a second return address from the current CRS and fetches an instruction at the second return address, if the instruction is a return instruction.

A predictive video coder performs gradient prediction based on previous blocks of image data. For a new block of image data, the prediction determines a horizontal gradient and a vertical gradient from a block diagonally above the new block (vertically above a previous horizontally adjacent block). Based on these gradients, the encoder predicts image information based on image information of either the horizontally adjacent block or a block vertically adjacent to the new block. The encoder determines a residual that is transmitted in an output bitstream. The decoder performs the identical gradient prediction and predicts image information without need for overhead information. The decoder computes the actual information based on the predicted information and the residual from the bitstream.
The present application is directed to techniques and tools for adapting the quantizer as well as the quantization step size used during video encoding. For example, a video encoder uses a non-uniform quantizer (having a relatively large dead zone ratio) for B-picture types, but uses a uniform quantizer for other types of pictures. In many encoding scenarios, this helps the encoder control bit rate for the B-picture types instead of resorting to higher quantization step sizes, which improves overall quality for the B-picture types.

A multipath data communication network structure in which probing middle-boxes send periodical probe messages through their different interfaces and subsequent routers map the probe messages through their randomly selected interfaces until each probe message arrives at a destination, engages to a loop or meets a time-to-live limit. The probing middle boxes select a random interface for each probe message and furnish their routable identification and a temporary random number correlated to the selected interface to each probe messages.

According to an approach for configuring Wi-Fi devices, a wireless access point changes its mode of operation from a normal operating mode to a configuration operating mode to configure one or more Wi-Fi devices. When operating in the configuration operating mode, it is more difficult for an eavesdropper to intercept messages between the wireless access point and the Wi-Fi devices being configured. Upon completion of the configuration process, the wireless access point changes its mode of operation from the configuration operating mode back to the normal operating mode. This approach reduces the likelihood of an eavesdropper intercepting configuration messages exchanged between a wireless access point and one or more Wi-Fi devices during the configuration process. The approach also allows automated configuration of Wi-Fi devices and reduces the amount of user interaction required to configure Wi-Fi devices.

The position of a disturbance on an optical link is evaluated, in particular where the disturbance is a time-varying disturbance. An optical time domain reflectometry technique is used in which a series of low coherence test pulses is launched by means of an optical pulse source into an the optical link, and the backscattered return signal is monitored. The test pulses pass through an unbalanced Mach Zhender interferometer with the result that for each test pulse, a pair of time-displaced pulse copies is launched onto the link. The backscattered return signal is passed through the same interferometer, which causes the pulse copies of each pair to become realigned and to interfere with one another. A time-varying disturbance is likely to affect each pulse copy of a pair differently. As a result, an abnormality such as a step is likely to occur in the backscattered signal. From the time position of an abnormality, the distance of the disturbance responsible is evaluated.

A rail-rail comparator having an input stage with independent positive and negative differential voltage offset compensation tracks changes in Gm (transconductance) of the input stage.
