Abstract: A system which includes a disk drive or other storage device coupled to a host system provides for reduction of the amount or rate of drive power consumption using procedures which are at least partially executed on the host. The system can be configured to reduce average power draw, maximum power draw, or both. Host-based procedures can be tailored to specific and/or changing environments and can decrease some or all expenses associated with previous attempts to reduce HDD power consumption.

Abstract: A high voltage capacitor design is provided that provides improved performance. The high voltage capacitor includes a stack of mechanically bonded capacitor cells, which in one variant utilize a separator formed of two layers of paper. In one version, the high voltage capacitor may be used as a capacitative voltage divider.

Abstract: A method of automatic contrast correction comprises providing digital image data, representing the data in the form of a brightness histogram, determining a measure of central tendency for said histogram, adding a shift value to the measure of central tendency to provide an adjusted measure of central tendency, using the both the determined and adjusted measures of central tendency to determine the exponent of a tone reproduction curve, and applying the tone reproduction curve to the brightness values of the image. Additionally, the method may provide further correction by applying to the brightness values of the image an S-shaped tone reproduction curve that does not change a measure of central tendency of the brightness histogram.

Abstract: Active electrode material, such as fibrillized blend of activated carbon, polymer, and conductive carbon, is pretreated by immersion in a sealing coating. After the active electrode material is dried, the coating seals micropores of the activated carbon or another porous material, thus preventing exposure of water molecules or other impurities trapped in the micropores to outside agents. At the same time, the sealing coating does not seal most mesapores of the porous material, allowing exposure of the mesapores' surface area to the outside agents. The pretreated active electrode material is used for making electrodes or electrode assemblies of electrical energy storage devices. For example, the electrodes may be immersed in an electrolyte to construct electrochemical double layer capacitors. Pretreatment with the sealing coating reduces the number of water molecules interacting with the electrolyte, enhancing the breakdown voltage of the capacitors.

Abstract: Differential delay-line analog-to-digital (A/D) converters for use in current and power sensing applications are provided. These A/D converters are well suited for a wide range of electronic applications, including over-load protection, current mode control, current sharing in digitally controlled switched-mode power supplies, power sensing, and implementation of power optimization methods in power management applications.

Abstract: Systems and methods for displaying network node ports and related information in a network topology display. The user is able to clearly view ports of a connection device in the network and to view additional port information, such as the port type and the port number, for connected and unconnected ports of a network connection device. In addition, the user is able to toggle between a “show ports” mode and a “hide ports” mode for each connection device to view detailed information about the connection device ports or to hide the information in order to simplify the display.

Abstract: High reliable energy density capability of double-layer capacitor electrode technology now enables the use of capacitors as supplements to, or replacements for, battery technologies. In one application, when sized to a standard battery form factor, the large end terminal surface areas of such form factors enable that the energy density of capacitors can now be safely used as direct drop-in replacements for batteries.

Abstract: A dry process based capacitor and method for making a self-supporting dry adhesive electrode film for use therein is disclosed.

Abstract: A combination pet collar and leash includes a leash that is attached to the collar and is fastened about the collar when not in use. When fastened about the collar, the leash conforms to the collar around the neck of a pet. When unfastened from the collar, the leash extends to a length to provide comfortable separation distance between a person holding the leash and the pet wearing the collar while allowing for appropriate control of the pet.

Abstract: A system and method for managing the allocation of Time Division Multiplexing (TDM) timeslots in a network switch. The network switch may use a TDM cycle comprising multiple timeslots to manage shared resources and to schedule data ingress and egress through the ports of the current configuration, wherein each port is assigned one or more timeslots. The network switch may be reprogrammed to support one of multiple timeslot assignment schemes for one of multiple port configurations. The network switch may support configurations with varying numbers of ports, e.g. 8- and 16-port configurations. A network switch may also support configurations where two or more ports are combined to form one port, for example, a 2 Gbs Fibre Channel port. To meet the requirements of the various configurations, the timeslot assignment scheme may be reprogrammed to meet the scheduling requirements of each of the possible port configurations.

Abstract: In a wide area network arrangement composed of some number of secure local networks and an Internet service provider (ISP) back-bone, LAN hosts are able to indirectly access network routers, through an ISP quality of service (QoS) module, to request that information transmitted during certain specified sessions be given priority treatment by the network.

Abstract: A mechanism to measure voice call quality in a Voice over IP (VOIP) network using a single voice call quality test probe is described. VOIP communications devices, such as gateways, that are deployed at various points along the border of the VOIP network each are configured to play an embedded reference voice file in response to test calls placed by the test probe to those devices. The test probe measures voice call quality by recording the played voice file and comparing it to the test probe's own copy of the reference voice file. The comparison uses a standard voice call quality analysis algorithm, such as Perceptual Analysis Measurement System (PAMS) or Perceptual Speech Quality Measurement (PSQM).

Abstract: A method for reducing image noise in a digital image including establishing image data of image pixel values; specifying a local virtual surface patch; fitting the local virtual surface patch to the image data; using the local virtual surface patch to estimate a palliative value of at least one pixel in the region of the local virtual surface patch; replacing an original pixel value with the palliative value.

Abstract: A programmable dopant fiber includes a plurality of quantum structures formed on a fiber-shaped substrate, wherein the substrate includes one or more energy-carrying control paths, which pass energy to quantum structures. Quantum structures may include quantum dot particles on the surface of the fiber or electrodes on top of barrier layers and a transport layer, which form quantum dot devices. The energy passing through the control paths drives charge carriers into the quantum dots, leading to the formation of “artificial atoms” with real-time, tunable properties. These artificial atoms then serve as programmable dopants, which alter the behavior of surrounding materials. The fiber can be used as a programmable dopant inside bulk materials, as a building block for new materials with unique properties, or as a substitute for quantum dots or quantum wires in certain applications.

Abstract: A method of correcting image saturation is performed by defining saturated colors in a chromaticity color space; and deriving an overall correction of the saturation of colors in the image using the defined saturation of these colors in conjunction with a table of corrections indexed by hue and lightness. This process has a unique attribute of being able to automatically decrease saturation in regions of an image where oversaturation is detected.
