US Classification:

340 552, 340 553, 340 582

Abstract:

Operating a remote control to identify a user by receiving touch pad input from at least one touch sensitive element of the remote control that has a plurality of touch sensitive elements. The touch pad input corresponds to the user's touch of at least some of the plurality of touch sensitive elements. The touch pad input is at least partially processed by processing circuitry of the remote control and transmitted to a multimedia system console via a communications interface of the remote control for processing of the at least partially processed touch pad input to identify the user via pattern recognition. At least partially processing the touch pad input can be by identifying at least one finger orientation, at least one finger spacing, at least one finger width, a plurality of finger knuckle/joint locations, and/or a plurality of finger lengths based upon the touch pad input.

International Classification:

A63F 13/06

US Classification:

463 37

Abstract:

A game controller with a communications interface, at least one touch sensitive pad having a plurality of touch sensitive elements, and processing circuitry coupled to the communications interface and the at least one touch sensitive pad. The processing circuitry receives touch pad input via the plurality of touch sensitive elements of the at least one touch sensitive pad. The processing circuitry then transmits the touch pad input to a game console via the communications interface. The touch sensitive pad can have a plurality of separate and distinct touch sensitive pads, allowing the processing circuitry to receive touch pad input via each of the plurality of separate and distinct touch sensitive pads. Touch pad input could include user finger and/or user thumb touch pad input.

US Classification:

463 37

Abstract:

Operating a gaming system having a game console and a game controller by receiving touch pad input from at least one touch sensitive pad of the game controller that has a plurality of touch sensitive elements. The touch pad input corresponds to a user's touch of at least some of the plurality of touch sensitive elements. The touch pad input is at least partially processed by processing circuitry of the game controller to produce partially processed touch pad input and transmitted from the game controller to the game console via communications interfaces of the game controller and the game console. The game console processes the at least partially processed touch pad input to produce game alteration data. The at least one corresponding game operation is altered based upon the game alteration data.

The touch pad input corresponds to the user's touch of at least some of the plurality of touch sensitive elements. The touch pad input is at least partially processed by processing circuitry of the game controller and the at least partially processed touch pad input is transmitted to a game console via a communications interface of the game controller for use as gaming input. At least partially processing the touch pad input can be by determining hand/foot position, changes in hand/foot position, hand grip/foot pressure, changes in hand grip/foot pressure based upon the touch pad input.

Abstract:

A method of determining the suitability of a surfactant for use in a formation can include sampling water in the formation, providing at least two surfactants, and mixing each of the surfactants with the formation water to form surfactant/water samples. The method can further include determining the solubility of each surfactant with the formation water, comparing the solubility of each surfactant with the other surfactant, and assigning a solubility performance value for each surfactant based on its solubility in the formation water sample compared to the other surfactant.

C23F 11/14

Abstract:

Compounds comprising multiple hydrophilic heads and a lipophilic tail may be contacted with a metal or other surface so as to adhere to the surface and inhibit corrosion, among other things. Suitable hydrophilic heads may include quaternary ammonium cation moieties, phosphonium cation moieties, and combinations thereof. Such corrosion-inhibiting compounds may be introduced into a wellbore penetrating at least a portion of a subterranean formation, for instance in oil and/or gas recovery operations and the like, whereupon the compound may adhere to a metal or other surface downhole so as to inhibit corrosion of the surface. These compounds may be employed in various other environments, such as any metal or other surface that may be exposed to corrosive conditions.
