20130120630 | SYSTEM AND METHOD FOR CONTROLLING TEMPERATURE IN MOBILE DEVICE - A temperature control system of a mobile device is provided. The system includes a memory for storing a set temperature value and a release temperature value, a temperature sensor for sensing an internal temperature of the mobile device; at least one module that emits heat, and a controller. The controller compares the output of the temperature sensor with the set temperature value in a normal mode in order to determine whether the mobile device is overheated, and controls, if the mobile device is overheated, the at least one module to operate in a heat generation suppressing mode, compares the output of the temperature sensor with the release temperature value in the heat generation suppressing mode in order to determine whether to release the heat generation suppressing mode, and executes the normal mode if the heat generation suppressing mode is released according to the comparison result. | 05-16-2013 |

20130081750 | ACTIVELY CONTROLLED VIBRATION WELDING SYSTEM AND METHOD - A vibration welding system includes a controller, welding horn, an active material element, and anvil assembly. The assembly may include an anvil body connected to a back plate and support member. The element, e.g., a piezoelectric stack or shape memory alloy, is positioned with respect to the assembly. The horn vibrates in a desirable first direction to form a weld on a work piece. The element controls any vibrations in a second direction by applying calibrated response to the anvil body in the second direction. A method for controlling undesirable vibrations in the system includes positioning the element with respect to the anvil assembly, connecting the anvil body to the support member through the back plate, vibrating the horn in a desirable first direction, and transmitting an input signal to the element to control vibration in an undesirable second direction. | 04-04-2013 |
20130081753 | PASSIVELY DAMPED VIBRATION WELDING SYSTEM AND METHOD - A vibration welding system includes a controller, welding horn, an anvil, and a passive damping mechanism (PDM). The controller generates an input signal having a calibrated frequency. The horn vibrates in a desirable first direction at the calibrated frequency in response to the input signal to form a weld in a work piece. The PDM is positioned with respect to the system, and substantially damps or attenuates vibration in an undesirable second direction. A method includes connecting the PDM having calibrated properties and a natural frequency to an anvil of an ultrasonic welding system. Then, an input signal is generated using a weld controller. The method includes vibrating a welding horn in a desirable direction in response to the input signal, and passively damping vibration in an undesirable direction using the PDM. | 04-04-2013 |
