| 20090140604 | HARVESTING ENERGY FROM FLOWING FLUID - Electrical energy is produced at a remote or close site by converting kinetic energy from fluid flow with membranes that generates electrical energy in response to deformation by the fluid flow passing though a piezo electric medium attached to the deforming membranes. Sets of membranes define variable fluid flow restrictors that oscillate due to interaction of the force of fluid flow and Bernoulli Effect.

| 20090211751 | FIELD-RESPONSIVE FLUIDS - A field-responsive fluid which enters a semi-solid state in the presence of an energy field is improved by use of a plurality of energy field responsive particles which form chains in response to the energy field.

Further, a multi-phase base fluid including a mixture of two or more substances, at least two of which are immiscible, may be used. The multi-phase base fluid improves the field-responsive fluid because surface tension between the boundaries of the immiscible substances in conjunction with chains formed by field-responsive particles tends to stop or retard creep flow, resulting an improved dynamic or static seal. | 08-27-2009 |
| 20090230335 | TEMPERATURE TRIGGERED ACTUATOR - An actuator is disclosed which operates on the principle of the variable magnetic properties of materials with respect to temperature. As temperature is raised past Curie temperature, magnetic permeability of certain materials drops significantly to a value close to free space permeability. However, depending on the material selection, magnetic permeability may be significantly higher below Curie temperature. This principle is used to cause magnetic attractive force to move an actuator at one temperature, while permitting a return spring force to move the actuator at another temperature by changing the pathway traversed by most magnetic lines of flux from a magnetic source. The actuator may be employed to provide a temperature activated electrical switch or fluid valve. The temperature activated valves are suited to use in high temperature environments, such as SAGD wells. | 09-17-2009 |
| 20090272579 | STEERABLE BIT - Steerable drilling systems for facilitating drilling according to a prescribed, three-dimensional trajectory are described.

For example, damping elements which couple a drill bit to a drill collar can be used to tilt the drill bit with respect to the drill collar. Alternatively, rotary cutting elements disposed on the drill bit may be used to control the force between the drill bit and the formation at different axial locations. The passive elements used to control the tilt or rotation of the rotary cutting elements are actuated in a certain pattern, e.g., geostationary, in order to achieve a desired deviation of the well bore while drilling ahead. One way to achieve this is through the use of field-sensitive materials, e.g. magnetorheological (MR) fluids, that change viscosity in response to an applied magnetic field. | 11-05-2009 |

The field which aligns the particles is moved, thereby causing the walls of aligned particles to move. Because traversal of the walls by the fluid is inhibited, fluid is displaced by movement of the walls of aligned particles. A reciprocating positive displacement pump can be provided by ceasing particle alignment and returning the particles to a starting position. Objects may also be moved in response to collision with chains or walls of aligned particles that move in response to field movement. Fluid circulation features are provided for preventing agglomeration of particles when translating torque between plates in relative rotational movement. | 03-04-2010 |
