20090327074 | METHOD AND APPARATUS FOR ADVERTISING SPECTRUM IN A COMMUNICATION SYSTEM - The application discloses a method and apparatus for advertising a spectrum in a wireless communication system. The method includes obtaining an address of a broker device authorized to negotiate access to the spectrum, and sending an inquiry message to the broker device for negotiating access to at least a portion of the spectrum. The method then includes receiving an agreement message including an advertisement text from the broker device when the first user device agrees to negotiating terms associated with the broker device. The advertisement text includes information related to the portion of the spectrum and the broker device. The method further includes transmitting a packet including the advertisement text to at least one other user device such that the at least one other user device communicates with the broker device for allocation of the portion of the spectrum. | 12-31-2009 |

20120187925 | DETECTION OF INSUFFICIENT SUPPLIED POWER - A method, apparatus, and device provide for the detection of insufficient supplied power supplied to a device. A current multiplier of the device, operable as a voltage regulator, is coupled to the power source, receives a clock signal, and generates a control signal. A digital counter, clocked by the clock signal and reset by the control signal, generates an overflow output in response to an overflow condition of the digital counter that indicates that the current sourcing capability of the power source has fallen below a current threshold of the device. A compensatory response by the device in response to the detection of insufficient supplied power may be provided as well. | 07-26-2012 |
