To form a solder joint between the metal antenna resonating element traces and the sheet metal of the antenna ground, laser light may be applied to the sheet metal of the antenna ground in the vicinity of the solder paste. Separate metal members may also be provided in the vicinity of the solder paste and may be heated using the laser to join metal traces on plastic carriers. |

Cavity resonator with thermal compensation
An exemplary cavity resonator has a resonant frequency and includes a conductive body containing a cavity and a plate attached to the body enclosing the cavity. The position of a conductive tuning mechanism that protrudes into the cavity affects the tuning of the resonant frequency of the cavity resonator. A portion of the enclosed cavity is made of a shape memory alloy (SMA) material that has been trained to have a coefficient of thermal expansion that results in dimensional changes of the portion as the temperature varies so that the dimensional changes produce changes in the resonant frequency that counteract the combined change in the resonant frequency due to dimensional changes with temperature associated with the other portions of the enclosed cavity made of materials other than SMA material. This results in a stable resonant frequency versus temperature characteristic. |

Cooling mechanism for batteries using L-V phase change materials
A 3-D “phase change heat exchange” structure and method are used in a rechargeable battery to dissipate heat from surfaces of the battery cells and lower the temperature inside the battery cells. The battery cells are placed inside an enclosure and spaced apart from each other with free spaces in between. A liquid to vapor phase change material (L-V PCM) is provided inside the enclosure. A hydrophilic thin film or wick or fiber structure is provided on the cell surfaces to help form a thin liquid layer of the L-V PCM over cell surfaces. During operation, the L-C PCM is evaporated at the cell surfaces and condenses back to a liquid either on the battery enclosure or in an external heat exchanger, and drips back on top of the cells. The designs extend the battery life and improve the battery performance significantly. |
