Abstract:
A method of controlling target aquatic microorganism pest populations by exposing the target population to an effective amount of an aquacidal compound. The aquacidal compounds are selected from the group consisting of quinones, anthraquinones, naphthalenediones, quinine, warfarin, coumarins, amphotalide, cyclohexadiene-1,4-dione, phenidione, pirdone, sodium rhodizonate, apirulosin and thymoquinone. The method is particularly effective for treating ballast water of ships or other enclosed volumes of water subject to transport between or among geographic areas to control the relocation of plants, toxic bacteria, and animals contained in the water.
Abstract:
The concentration of adsorbate in the feed gas to an on-stream bed of a cyclical swing adsorption process is monitored and the data processed to predict the time required to complete the on-stream mode of that bed and the purge flow rate and/or other regeneration mode operating condition of the concurrently off-stream bed is modified in response to changes in said predicted time whereby the regeneration mode of the off-steam bed is completed at the same time as the on-stream mode of the concurrent on-stream bed.
Abstract:
The present invention includes systems and methods for customization of internet applications. Multiple levels of customization are applied to both static and functional aspects of user interface elements including, for example, tab-order, tab-over, immediate access keys, and hotkeys. Customization is also achieved with respect to searching over multiple user interfaces, presentation of information on a user interface, and the interaction model used by the internet application. Customization is enabled on any client supporting standard browser functionality.
Abstract:
Method and apparatus for enabling authentication of e-mail messages. A message code is embedded in an e-mail, where the message code can be used by the recipient to verify the authenticity of the e-mail. In some embodiments, this code can be created for a particular e-mail message; in other embodiments, the code is created as a watermark for use in all e-mail to a specific recipient. The message code is associated with both the e-mail message and the recipient. In the case of a message-specific code, a recipient can verify the e-mail message by inputting the code via a Web server to be looked up in the database. The invention can be implemented in a system including a server which creates e-mail messages and injects message codes and a database for storing codes and recipient e-mail addresses.
Abstract:
A hand-held multi-dose dispensing apparatus (10) comprising a metering chamber (20) having an axis (21), an end portion (22) at one axial end of the chamber (20) and a side body portion (23) extending from the axial end portion (22), a piston arrangement (30) movable with a piston stroke along the axis of the metering chamber (20) with a seal portion (34) of the piston arrangement (30) being slidably engageable with an inside surface of a side portion (23) of the metering chamber, an inlet (27) for fluid to enter the metering chamber (20), and an outlet (31, 32) for fluid to be dispensed from the metering chamber (20), wherein the inlet (27) is provided on the side body portion (23) of the metering chamber and, in use, during a first portion of the piston stroke, the inlet (27) is in fluid communication with the metering chamber (20) and during a second portion of the piston stroke, the seal portion (34) of the piston arrangement (30) blocks the inlet (27) preventing fluid from passing from the inlet (27) into the metering chamber (20). This dispensing apparatus (10) reduces variations in the shot weight dispensed, by the metering of the fluid commencing at the point at which the piston enters the second portion of its stroke blocking off the inlet.
Abstract:
Embodiments of the invention relate to a method and apparatus to reduce power consumption in a passive matrix LCD driver circuit by using a plurality of drive buffers and active power management of sub-blocks in the passive matrix LCD drive circuit. Each drive buffer may operate in a first phase, which may include a high-drive mode to drive an LCD voltage to a threshold voltage level and a low-drive mode to modify the LCD voltage to approximate an input voltage of the drive buffer, and to maintain a constant LCD voltage level. The low-drive buffer consumes less current than the high-drive buffer, thus reducing power consumption. The drive buffer may also operate in a second phase, also a no-drive mode, in which the drive buffer and the bias voltage generator may be completely turned off, to further reduce power consumption. The drive buffer may be used to drive capacitive loads, as well as partially-resistive loads and inductive loads.
Abstract:
Embodiments of the invention relate to a method and apparatus to drive non-resistive loads. The non-resistive load driver may include two or more drivers, such as a high-drive circuit and a low-drive circuit, to drive rail-to-rail output voltages and to stabilize the output voltages at a substantially constant level. The high-drive circuit may drive the output voltage of the non-resistive load driver to a threshold level, whereas the low-drive circuit may modify the output voltage of the non-resistive load driver to approximate an input voltage of the non-resistive load driver, and compensate any leakage associated with the non-resistive loads to provide a substantially constant output voltage. The low-drive circuit consumes less current than the high-drive circuit. The non-resistive load driver consumes less power and use less chip space. Alternatively, the non-resistive load driver may be implemented using a single driver with multiple modes, such as a low-drive mode and a high-drive mode, by changing a bias current of the non-resistive load driver between a high current mode and a low current mode.
