Abstract: A method for transferring data may include receiving data from a monitoring device, determining whether the subject being monitored has a condition that may require attention, and sending a notification message to a portable electronic device that is designed to be carried by a caregiver if such a condition exists. The notification message may be sent using one or both of a first wireless data transfer method and a second wireless data transfer method. The system may use both methods to communicate with one device or may use the first method to communicate with a first device and the second method to communicate with a second device. The portable electronic device may include two wireless transceivers such as a transceiver designed to connect the device to a local area network of a facility and a transceiver designed to connect the device to a cellular network.

Abstract: An improved WLAN solution for embedded systems incorporating optimized partitioning; it reduces power consumption and systems cost by up to 50%. All silicon gates associated with the redundant RISC processor, redundant SRAM and flash memories used in prior art WLAN solutions are eliminated. The invention includes a low gate count PHY Accelerator ASIC, a dual core processor (DCP), a portion of the PHY in software, and an innovative software MAC architecture supported by minimal hardware acceleration. The DCP is a standard off-the-shelf component incorporating DSP and RISC processors. It executes software portions of the MAC and PHY. The DCP communicates with the PHY Accelerator through a novel parallel interface that improves throughput while reducing processing requirements on DCP. Also, the PHY accelerator, or certain portions of it, may be embedded into the DCP. Invention includes a novel “resource utilization scheme”, whereby the various DCP resources get judiciously re-deployed.
