摘要： Methods and apparatus for enhancing efficiency (e.g., reducing power consumption and bus activity) in a data bus. In an exemplary embodiment, a client-driven host device state machine switches among various states, each comprising a different polling frequency. A client device on the data bus (e.g., serial bus) checks for non-productive periods of polling activity, and upon discovering such a period, informs the host. The state machine then alters its polling scheme; e.g., switches to a lower state comprising a reduced polling frequency, and polling continues at this reduced frequency. In one variant, the client device continuously monitors itself to determine whether it has any data to transmit to a host device and if so, the host is informed, and the state machine restarts (e.g., to its highest polling state). By eliminating extraneous polling, power consumption and serial bus activity is optimized, potentially on both the host and the client.

摘要： Methods and apparatus for dynamically adjusting the amount of power (or current) distributed to one or more connected devices via electrical interfaces. In one embodiment, the apparatus comprises a first module adapted to detect current drawn by a first set of ports, and a second module adapted to adjust the current provided to a second set of ports based on the detected current. The second module is also optionally adapted to distribute unreserved current among the devices according to an allocation protocol. In the exemplary context of a plurality of interconnected serial bus devices, the invention enables a device to draw more current than that required to be reserved for that device (such as to comply with a specification such as USB), yet without increasing the total amount of power which must be dedicated to the serial ports as a whole. Power supply efficiency may also be advantageously optimized.

摘要： The present invention provides an enzymatically active composition for suppressing sulfide generation. The composition is free from sulfur dehydrogenase and comprises at least one enzyme having sufficient sulfide-production inhibiting activity in an acidic medium to at least inhibit biogenic sulfide production, and an oxidized nitrogenous inorganic salt present in an amount sufficient to act as an electron acceptor for the enzyme. The oxidized nitrogenous inorganic salt preferably is selected from an alkali metal nitrite, an alkaline earth metal nitrite, an alkali metal nitrate, an alkaline earth metal nitrate, or a mixture of two or more of the foregoing salts. The enzymatically active composition is free from viable bacteria and is non-toxic (i.e., has an oral LD50 in rats greater than 1000 mg/Kg of body weight at a concentration of about 25,000 parts per million (ppm) in water). The compositions of the present invention are useful for treating and removing biofilms, as well as inhibiting sulfide production in a variety of aqueous systems.

摘要： A display control system for a multi-layer display system including at least one multi-layer display unit (6). A multi-layer display unit includes multiple stacked or overlapped display layers (1a, 1b, 1c, 14, 15) each adapted to render display elements (2, 16B, 17B, 18B) thereon for viewing through the uppermost display layer. The level of difficulty for a user to view an overlapped image differs depending on the colour, brightness or type of images (for example text-on-text) being displayed and also the layer in which the image is being displayed and whether the image is currently active. At least any overlapping portion of display elements from different display layers are adjusted (automatically or by a user) in order to improve the viewing experience for a viewer. Types of adjustment possible include moving the images within their display layer or to an alternative display layer or altering their visual properties (such as colour, brightness, contrast etc).
