  • Publication number: 20160249361
    Abstract: In order to improve the quality of communication between electronic devices, one or more sub-channels used during communication between the electronic devices are dynamically modified based on one or more performance metrics and allowed transmit powers of the sub-channels. In particular, when the one or more performance metrics indicate that a distance between the electronic devices falls within a mid-range of distances, the one or more performance metrics may be used to guide selective changes to the sub-channels used during the communication based on the allowed transmit powers. The changes to the sub-channels used during the communication may increase, decrease or leave the total bandwidth unchanged. Moreover, by changing the sub-channels used during the communication, the allowed transmit power(s) of the sub-channel(s) used may be increased, which may improve the performance during the communication.

  • Publication number: 20160152467
    Abstract: A method for fabricating a MEMS device includes providing a substrate having a front surface and a back surface, and forming a protruding engagement member on the front surface of the substrate. The protruding engagement member has an inner periphery defining a groove and an outer periphery. The method also includes forming a first trench having a first depth along the outer periphery, forming a patterned mask layer on the protruding engagement member covering the groove and exposing a portion of the first trench. The method further includes etching the exposed portion of the first trench to form a second trench having a second depth, removing the patterned mask layer, bonding the substrate with a MEMS substrate to form the MEMS device, and thinning the back surface to within the second depth. The method prevents dust from being deposited on the MEMS substrate as in the case of cutting.

  • Patent number: 9231686
    Abstract: Dynamic antenna switching based on weighted signal to noise ratio (SNR). A wireless device may include multiple antennas. SNR at each active antenna may be calculated. An antenna-specific weight may be applied to each antenna's SNR. The antenna-specific weights may further be radio specific and/or transmit or receive specific in some cases. Antenna selection (possibly just for a specific radio and/or for transmit or receive operations, depending on the specificity of the antenna weights), including potentially switching which antenna is used, may be based on the resulting weighted SNR values for each antenna. If the antenna-specific weights are radio specific and/or transmit or receive operation specific, the method may be performed multiple times with different antenna-specific weights to select antenna(s) for different radios and/or for other operations.
