20130029227 | POLYANION ACTIVE MATERIALS AND METHOD OF FORMING THE SAME - A method of forming a polyanion active material that includes providing a carbon source, providing a mobile ion source, providing an active metal material, providing a network material, providing a flux material, and mixing the various materials. In one aspect, the mixing step may include grinding or pulverizing materials to a uniform fine mixture. In one aspect, a ball mill may be utilized to mix the components. Following the mixing of the materials, the mixture is heated to a predetermined temperature in a non-oxidizing atmosphere to form a reaction product. In one aspect, the mixture is heated to a temperature above a melting temperature of the flux material. In this manner, the flux material provides a medium in which the various reactants may react to form the desired reaction product. Following the heating of the mixture the reaction product is washed, forming a carbon coated polyanion active material. Also disclosed is a polyanion active material that includes the in situ reaction product of a carbon source, mobile ion source, active metal material, network material, and a flux material wherein the polyanion active material includes a carbon coating formed thereon. | 01-31-2013 |

20130277155 | HIGH THERMAL CONDUCTIVITY DISK BRAKES - An automotive disk brake assembly installed in an automobile having a wheel. The assembly includes a floating caliper supporting inner and outer brake pads and a brake rotor having a disk, a hat, wherein the hat is bolted to the wheel. A hydraulic cylinder pushes the inner brake pads into the disk surface, thereby causing the floating caliper to move so as to bring the outer brake pad into contact with the disk surfaces. Finally, the rotor is made of a material having a thickness and a coefficient of thermal expansion and conductivity, such that a complete 100 kilometer per hour, 0.9 gross vehicle weight braking causes the disk to expand in thickness by at least 0.10 mm and to cool to shrink in thickness, from its expanded thickness, by at least 0.05 mm within 60 seconds of cessation of braking, in an ambient temperature of less than 30° C. | 10-24-2013 |
20130277157 | HIGH THERMAL CONDUCTIVITY DISK BRAKES - An automotive disk brake assembly installed in an automobile having a wheel. The assembly includes a floating caliper supporting an inner and outer brake pad and a brake rotor having a disk, and a hat, and wherein the hat is bolted to the wheel.

20140162843 | TRANSMISSION WITH MEMS-BASED HYDRAULIC CIRCUIT - A vehicle includes an engine, torque converter assembly, and transmission. The torque converter assembly includes a torque converter clutch (TCC). The transmission is connected to the engine via the torque converter assembly, and includes rotating and braking clutches, a pump, and a valve body assembly (VBA). The VBA includes Micro Electro Mechanical Systems (MEMS) pressure sensors and high-flow, hybrid MEMS flow control valves. Each MEMS pressure sensor and each MEMS control valve is in fluid communication with a corresponding one of the TCC, the rotating, and the braking clutches. The VBA includes first and second low-flow, fully MEMS valves which control line pressure to the VBA and fluid pressure to the TCC, respectively. The VBA delivers fluid pressure to the clutches, alone or in different combinations, to establish at least six different forward drive states of the transmission. | 06-12-2014 |
20150316167 | METHOD OF CONTROLLING A MICRO-ELECTRO-MECHANICAL SYSTEM (MEMS) VALVE - A method of controlling a Micro-Electro-Mechanical System (MEMS) valve includes defining a desired pressure output for the MEMS valve. The desired pressure output is related to a control reference value. The control reference value relates an output pressure of the MEMS valve to a measurable characteristic of the MEMS valve. The measurable characteristic may include a resistance, an electrical power, or an electrical current of the MEMS valve. The control reference value is converted to an initial Pulse Width Modulated (PWM) signal that is applied to the MEMS valve. The initial PWM signal may be adjusted to define an adjusted PWM signal based upon a difference between an actual value of the measurable characteristic at the initial PWM signal and the control reference value, until the actual value of the measurable characteristic at the adjusted PWM signal is within a pre-defined range of the control reference value. | 11-05-2015 |
