摘要:
A medical irrigation pump and pump system utilize a permanent non-sterile drive motor capable of operating disposable sterile single use pump units each of which is specifically designed for a particular medical procedure. The pump units have housings which are adapted to be interchangeable within the permanent controller system. Only the sterilized and disposable pump units come into contact with the fluid pathway during pumping. A pattern of bumps on each pump unit is unique for the medical procedure for which the pump unit was designed. The pattern of bumps engages switches on the controller, enabling the controller to identify what type of pump unit has been installed. After automatically identifying the type of pump unit and the intended medical procedure, the controller automatically selects a default motor speed that will provide an appropriate fluid pressure for that particular procedure. Buttons on a control panel also enable the user to manually adjust the pressure delivered by the pump. The orientation of the pump unit during the loading procedure allows easy purging of all air from the pump unit before the pump is started.

A method and apparatus of turning rotary components of a rotary machine having a brake disc includes providing a turning gear assembly. The turning gear assembly includes a gear plate, a pinion gear and a gear motor coupled to the pinion gear. The method also includes coupling the turning gear assembly within the rotary machine using the gear plate such that the pinion gear engages with the brake disc, detecting a motion of the rotary machine, and rotating the brake disc using the pinion gear based on the detected motion.

A method and apparatus for optimizing routing through a data network is disclosed. Plural simulations are run on various links between network routers, and a central location may be used to compile the information from the links and calculate parameters of paths through the network. A graphical user interface to specify parameters of the simulations is also provided.

A bond for a metal single layer abrasive tool can be easily chemically and electrochemically stripped from the metal core of a recovered used tool to facilitate reuse of the core. Relative to conventionally bonded tools, the speed of stripping the novel bond is quick, and the stripped core has a smooth, clean surface which needs only minimal mechanical repair prior to reuse. The composition of the novel bond consists essentially of copper, tin and titanium. It can be brazed at temperatures below diamond graphitization and is chemically compatible with diamond. Hence, the bond is particularly useful for the manufacture of large diameter, superabrasive metal single layer abrasive wheels employed in the construction industry. The bond can be applied to the cutting surface of the abrasive tool as a uniform mixture of bronze alloy, titanium compound and copper powders. The powders may be mixed with a liquid vehicle and applied as a paste. The method of brazing the bond incorporates heating the bond composition to a temperature at most about 880° C. to melt the bronze alloy and titanium compound components, and raising the temperature to at least about 900° C. to dissolve the copper. The bond can also include an about 10-200 &mgr;m thick barrier layer of copper coating the cutting surface between the core and the bond composition.

A magnetic sensor having adjustable electrical dimensions, such as electrical read width and electrical stripe height, is disclosed. The magnetic sensor includes a sensor stack with one or more bias electrodes positioned with respect to the sensor stack. The electrical width or electrical stripe height of the sensor stack is a function of a voltage applied to the bias electrodes. The electric field produced by the bias electrodes alters the electrical profile of the magnetoresistive device.

A tamper-resistant text stream watermarking system is provided. Content such as any text-based document including programming code is encoded with a watermarking mechanism. The mechanism modifies the text itself according to a preset repeating pattern without changing the substance. Examples include patterned use of white spaces, contractions, abbreviations, order of local variables in programming code, and the like. The pattern may include a binary fingerprint that can be used to trace the watermarked document to an assigned source or version of the original document. In analyzing a suspect text stream, patterns are generated based on instances of the mechanism and their corresponding bit values. Repeating patterns are combined into a bit stream along with separators between each pattern. The bit stream can then be analyzed to determine a source of the watermarked text stream.
摘要:
An animal resistant trash container lid has several transverse ridges cross the top. Longitudinal ridges are on the front of the trash container lid. Within the trash container lid is a frame. Holes in the front of the trash container lid are disposed to receive locks. The locks fasten the lid to the trash container. The trash container lid also has a handle and hinges integral with the frame and extending through the outer wall of the lid.
摘要:
The present invention is a modular system for mounting lighting and signage. Mount components are attached to gutters by engaging the securing protuberance of the mount component with the gutter which creates tension between the gutter and the mount component. Rail components are assembled to the desired length using connector components and lights or signage are attached to a rail component using hooks. An insertion member is placed at each end of the assembled rail and the rail is guided through an opening in the mount component securing the lights or signage to the building.

The present invention is an integrated housing mounting system for mounting ornamentation to buildings. Mount components are attached to a building in place of J-channel, J molding, drip edge, gutter apron or siding. Rail components are assembled to the desired length using connector components and lights or signage are attached to a rail component using hooks. A guide member is placed at each end of the assembled rail and the rail is guided through an opening in the mount component securing the lights or signage to the building. The rail components are then guided through an opening in the mount component.
