A computer data signal embodied in a propagation medium is provided. The signal enables a variable number of data transfers and includes an initial connection source code segment and a data transfer source code segment. The initial connection source code segment establishes a connection between at least two devices via predetermined listening ports, with at least one predetermined listening port residing within each device. The initial connection source code segment also dynamically assigns a first data port within a first device, and transmits the address of the first data port to a remaining device via the predetermined listening ports. The data transfer source code segment is for each of the variable number of data transfer operations. The data transfer source code segment dynamically assigns a corresponding second data port within the remaining device and transfers data between the connected devices via the data ports so that the data is substantially simultaneously transferred between a variable number of devices via the data ports. Each pair of first and second data ports is established in response to each listening port connection.

An adaptive replacement cache policy dynamically maintains two lists of pages, a recency list and a frequency list, in addition to a cache directory. The policy keeps these two lists to roughly the same size, the cache size c. Together, the two lists remember twice the number of pages that would fit in the cache. At any time, the policy selects a variable number of the most recent pages to exclude from the two lists. The policy adaptively decides in response to an evolving workload how many top pages from each list to maintain in the cache at any given time. It achieves such online, on-the-fly adaptation by using a learning rule that allows the policy to track a workload quickly and effectively. This allows the policy to balance between recency and frequency in an online and self-tuning fashion, in response to evolving and possibly changing access patterns. The policy is also scan-resistant. It allows one-time-only sequential read requests to pass through the cache without flushing pages that have temporal locality. The policy is extremely simple to implement and requires only constant-time overhead per request. The policy has negligible space overhead.

A skin stimulation system (200) is integrated into a piece of clothing or any type of wearable accessory (101, 101′) which is connected to a controlling device (109). The system comprises a variety of sensing means (105a-c, 105′) for input information. Actuators (106a-p) placed on or close to body of a person wearing this piece of clothing or wearable accessory (101, 101′) are used for generating (S104′) visual, auditive, tactile, gustatoric and / or olfactoric stimuli (e.g. heat, pressure, vibrational and / or electric pulses, etc.). The invention further specifies a new method for transmitting tactile information between different wearable computing devices (100, 100′). According to one embodiment of the present invention, a number of different actuator elements (106a-p) which are used for generating vibro-tactile sensations are integrated into a piece of jewelry such as e.g. a necklace (304), a bracelet, rings (900b) with a single or variable number of beads (900a), gemstones, etc. These actuator elements (106a-p) are embedded in detachable casings (306a1-a4) which are pivotable about their suspension axes. Each of said beads, gemstones, etc. or at least some of them includes at least one integrated actuator element (106a-p). The invention further pertains to a method for tuning (S901) key parameters of said stimuli by pivoting said casing (306a1-a4) about at least one axis so as to bring said actuator means (106a-p) closer to or farther away from parts of a user's body wearing said piece of clothing or wearable accessory (101, 101′). Said key parameters are e.g. the intensity, duration and / or frequency of said stimuli.

A computer system provides an improved graphical user interface by defining a view space in which graphical user interface windows from separate computer processes can be selectively located by a user. This view space has a plurality of discrete portions each large enough to hold a plurality of such user interface windows. The system enables users to selectively associate view space portions with physical locations external to the system's computing apparatus. The system also enables users to selectively locate a variable number of the user interface windows in each of the view space portions associated with such a physical location, including enabling the user to selectively move windows between such view space portions. The system detects when a user motions toward a given physical locations and responds to such a detection by presenting a visual display showing the given view space portion associated with the given physical location, together with any user interface window located in the given view space portion. In some versions of the invention, the physical location can be defined by a global positioning system and the system can detect when a user moves into a location defined by such global positioning.

An automated system that randomly generates test cases for use in hardware or software quality assurance testing, wherein a given test case comprises a sequence (or “chain”) of discrete, atomic steps (or “building blocks”). A particular test case (i.e., a given sequence) has a variable number of building blocks. The system takes a set of test actions (or even test cases) and links them together in a relevant and useful manner to create a much larger library of test cases or “chains.” The chains comprise a large number of random sequence tests that facilitate “chaos-like” or exploratory testing of the overall system under test. Upon execution in the system under test, the test case is considered successful (i.e., a pass) if each building block in the chain executes successfully; if any building block fails, the test case, in its entirety, is considered a failure. The system adapts and dynamically generates new test cases as underlying data changes (e.g., a building block is added, deleted, modified) or new test cases themselves are generated. The system also is tunable to generate test sequences that have a given (e.g., higher) likelihood of finding bugs or generating errors from which the testing entity can then assess the system operation. Generated chains can be replayed easily to provide test reproducibility.

An optical amplifying apparatus which includes an optical amplifier, an optical attenuator and a controller. The optical amplifier amplifies a light signal having a variable number of channels. The optical attenuator passes the amplified light signal and has a variable light transmissivity. Prior to varying the number of channels in the light signal, the controller varies the light transmissivity of the optical attenuator so that a power level of the amplified light signal is maintained at an approximately constant level that depends on the number of channels in the light signal prior to the varying the number of channels. While the number of channels in the light signal is being varied, the controller maintains the light transmissivity of the optical attenuator to be constant. Subsequent to varying the number of channels in the light signal, the controller varies the light transmissivity of the optical attenuator so that a power level of the amplified light signal is maintained at an approximately constant level that depends on the number of channels in the light signal subsequent to the varying the number of channels.

A pop-up toolbar is disclosed which is demonstrably faster and easier to utilize than the permanently displayed, horizontal toolbar. Two columns provide a variable number of irregularly shaped regions arrayed on either side of a generally circular central-area. Components of regions converge on the central area. Targets, each displaying an icon and an optional, descriptive label, appear within the regions. At pop-up of the toolbar, the cursor moves under system control to the central-area of the toolbar, enabling users to perform short, radial traverses of the cursor into targets, activating related functions by appropriate action. Alternatively, primary and secondary targets for regions may be designated for remote acquisition, whereby alternate user actions in any non-target area of a region activate the primary and secondary targets respectively defined for that region. The central-area is divided into a varying number of shapes permitting users to activate application, system, or toolbar management activities.

A harmonic suppression mixer for down converting an RF signal to a complex I and Q baseband signal that uses a plurality of switching mixers each with a gain stage to produce a sinusoidal weighted sum of the mixer outputs. Odd harmonics output by each switching mixer is suppressed in the composite signal. A low skew local oscillator (LO) clock generator creates multiple LO phases and drives the mixers. The mixer can be used in low noise direct conversion RF tuners. The mixer is configurable by programming gain stage coefficient values to achieve a variable number of effective mixers used in combination. At low tuning frequencies, all available mixers are programmed with unique coefficients and driven by different LO clock phases to achieve maximum harmonic suppression. At high tuning frequencies, some mixers are paralleled and duplicate coefficients are programmed or mixers are disabled to reduce the number of effective mixers.

An advanced data structure allows lookup based upon the most significant 16 bits and the following variable number of K bits of the IP destination address. This 16 / K scheme requires less than 2 MB memory to store the whole routing tables of present day backbone routers. A 16 / Kc version utilizes bitmaps to compress the table to less than 0.5 MB. For the 16 / K data structure each route lookup requires at most 2 memory accesses while the 16 / Kc requires at most 3 memory accesses. By configuring the processor properly and developing a few customized instructions to accelerate route lookup, one can achieve 85 million lookups per second (MLPS) in the typical case with the processor running at 200 MHz. Further, the lookup method can be implemented using pipelining techniques to perform three lookups for three incoming packets simultaneously. Using such techniques, 100 MLPS performance can be achieved.
