A composite paramagnetic particle and method of making are provided. In one aspect of the invention, a particle comprising a multitude of submicron polymer bead aggregates covalently cross-linked to each other to form larger diameter particles is presented. Distributed throughout the composite paramagnetic particle are vacuous cavities. Each submicron polymer bead has distributed throughout its interior and surface submicron magnetite crystals. In another aspect of the invention, composite particles are made using high energy ultrasound during polymerization of one or more vinyl monomers. In one embodiment, high energy ultrasound is used during an emulsification step and during the early stages of the polymerization process to produce micron sized composite paramagnetic particles. The particles according to the invention exhibit a high percent magnetite incorporation and water and organic solvent stability.

An interactive system for interacting with a sentient being. The system includes a robotic companion of which the sentient being may be a user and an entity which employs the robot as a participant in an activity involving the user. The robotic companion responds to inputs from an environment that includes the user during the activity. The robotic companion is capable of social and affective behavior either under control of the entity or in response to the environment. The entity may provide an interface by which an operator may control the robotic companion. Example applications for the interactive system include as a system for communicating with patients that have difficulties communicating verbally, a system for teaching remotely-located students or students with communication difficulties, a system for facilitating social interaction between a remotely-located relative and a child, and systems in which the user and the robot interact with an entity such as a smart book. Also disclosed are control interfaces for the robotic companion, techniques for rendering the robotic companion sensitive to touch and responding to those touches, and techniques for providing quiet, back-drivable motion to components of the robotic companion.

An inexpensive rain water collecting device which is easy to manufacture. The rain water collecting device provides an effective device which is adaptable to various umbrella tip sizes and avoids any bacterial growth problems. The rain water collecting device includes at least a reservoir having a first open end and a second open end, the first open end has an opening with an inner perimeter which is substantially equal to an outer perimeter of the umbrella tip, and the second open end has an opening with a perimeter which is greater than the inner perimeter of the opening of the first open end; a ferrule formed about the opening of the first open end; and at least one flow barrier about the second open end of the reservoir. After using an umbrella in the rain, it is collapsed. The rain water on the cloth of the umbrella then drains into the reservoir of the rain water collecting device.

A method of processing and passivating an implanted workpiece is disclosed, wherein, after passivation, the fugitive emissions of the workpiece are reduced to acceptably low levels. This may be especially beneficial when phosphorus, arsine, germane or another toxic species is the dopant being implanted into the workpiece. In one embodiment, a sputtering process is performed after the implantation process. This sputtering process is used to sputter the dopant at the surface of the workpiece, effectively lowering the dopant concentration at the top surface of the workpiece. In another embodiment, a chemical etching process is performed to lower the dopant concentration at the top surface. After this sputtering or chemical etching process, a traditional passivation process can be performed.

A system for determining when a cleaning process has completed is disclosed. This system relies on an increase in the amount of gas in the processing chamber that occurs when the cleaning is complete. This increase in the amount of gas may be detected in several ways. In one embodiment, a downstream pendulum valve is used to maintain the pressure within the processing chamber at a predetermined value. An increase in the size of the opening in the pendulum valve is indicative of the amount of gas in the system. In another embodiment, a sensor may be used to monitor the pressure within the processing chamber, while the incoming and outgoing flow rates are held constant. An increase in the pressure is indicative of an increase in the amount of gas in the processing chamber. This increase in the amount of gas is used to terminate the cleaning process.

A method may include providing a device structure, where the device structure includes a semiconductor region, and a gate structure, disposed over the semiconductor region. The gate structure may further include a gate metal. The method may further include oxidizing an upper portion of the gate metal, wherein the upper portion forms an oxide cap, and wherein a lower portion of the gate metal remains metallic.
