The class of k Nearest Neighbor queries in spatial networks has been studied in the literature. The actuator section includes a multilayered member including at least three actuator films, each of which include a PE layer and electrode films. The RAM is configured to retrieve, decode, and execute each of the time encoded RAM commands in the command queue. In another embodiment, only one of the switches is connected to the probe, and the other switches transmit their respective portions of the information to the switch connected to probe. The processing unit is provided with a keyboard and is connected to a remote control unit. During high ambient conditions, the fan speed is decreased, decreasing the refrigerant mass flowrate in the system.
