Paper presentation on power optimization for electrical engineers!
SAMPLE 1: A method and system for conserving battery strength of a mobile node, such as a laptop computer, on a wireless local area network (WLAN). The mobile node transmit symbols, which are units of data, during transmission cycles to maintain a connection with the WLAN. A battery charge level of the mobile node is measured. As the battery charge level drops below pre-defined levels, a frequency of symbol transmission for the mobile node is reduced. The reduction of the frequency of the symbol transmission results in lower power demands by a transmitter chipset of the mobile node. Thus, the mobile node is able to prolong the life of the battery of the mobile node.
SAMPLE 2: A method and apparatus are disclosed for improving the efficiency of operation of AC induction motors. The method and apparatus utilizes a microprocessor to tune a motor control system such that the time interval between the turn-on of a bi-directional switch and the time of sensing the resultant inrush current through the stator is maintained substantially constant as the load is varied.
SAMPLE 3: An RF transceiver includes a low noise amplifier module, a blocking circuit, a down-conversion module, a processing module, an up-conversion module, and a power amplifier module. The low noise amplifier module amplifies inbound RF signals. The blocking circuit, when enabled, substantially attenuates a blocking signal and passes, substantially unattenuated, desired receive RF signals of the inbound RF signals. The down-conversion module converts the amplified inbound RF signals or the desired receive RF signals into inbound baseband or low IF signals. The processing module converts the inbound baseband or low IF signals into inbound data, converts outbound data into outbound baseband or low IF signals
