More specifically, in order to solve a problem of the conventional art, in which the magnitude of power line communication signals exceeds a reference value allowed in the law, the apparatus controls a communication signal to be selectively output a communication target phase among phases of a three-phase power line. Accordingly, it is possible to maintain the magnitude of the output communication signal to be low. Further, it is possible to reduce distortion of a power signal, caused by the communication signal, and malfunction of other power facilities due to the distortion. Further it is possible to easily and simply perform initiation of the power line communication.

Abstract: Mis-programming of MSB data in flash memory is prevented by using ECC decoding logic on the flash die that error corrects the LSB values prior to the LSB values being used in conjunction with the MSB values to determine the proper reference voltage ranges. Error correcting the LSB page data prior to using it in combination with the MSB page data to determine the reference voltage ranges ensures that the reference voltage ranges will be properly determined and programmed into the flash cells.

Abstract: An anonymous non-emergency help system matches capabilities of potential helpers to a requestor's needs. Helpers identify the type of assistance they are willing to provide and then agree to become available anonymously. The helpers are contacted sequentially for assistance based on proximity to the requestor. The nearest helper may choose to respond or decline the request. This anonymous location process occurs sequentially, awaiting a requestor-defined timeout, until one of the identified individuals agrees to fulfill the request or until there are no other proximate individuals that meet the specific request criteria. A call for help is not broadcast, but helpers are chosen based on their disclosed skills/capabilities, attributes, and their proximity to the requestor. The attributes are related to at least one of speed and trajectory relative to the requestor, time the helper is in a particular location, and altitude difference between the requestor and the helper.
