Abstract: A system and method of performing synchronized measurements using wireless sensor devices is disclosed. A central device transmits a periodic advertisement that includes a special command instructing the wireless sensor devices to perform a measurement. Further, the periodic advertisement also includes measurement timing which defines the time that the measurement is to be performed. Additionally, the periodic advertisement may include measurement parameters, which provide information about the measurement to be performed. A periodic advertisement with response is then used to allow all of the wireless sensor devices to transmit their respective measurement data back to the central device. This may be used to perform one synchronized measurement or a plurality of measurements.

Abstract: Memory is allocated according to lifespan. The memory manager allocates requests for short-term memory to one portion of memory and allocates requests for long-term memory to another portion of the memory. The memory manager looks for free space for requests for long-term memory starting at a first location in the memory and the memory manager looks for free space beginning at a second location in the memory for requests for short-term memory. In that way, more memory banks are likely to be free and can be powered down to save power consumption, particularly during sleep states.
