A programmable metallization cell ("PMC") comprises a fast ion conductor such as a chalcogenide-metal ion and a plurality of electrodes (e.g., an anode and a cathode) disposed at the surface of the fast ion conductor and spaced a set distance apart from each other. Preferably, the fast ion conductor comprises a chalcogenide with Group IB or Group IIB metals, the anode comprises silver, and the cathode comprises aluminum or other conductor. When a voltage is applied to the anode and the cathode, a non-volatile metal dendrite grows from the cathode along the surface of the fast ion conductor towards the anode. The growth rate of the dendrite is a function of the applied voltage and time. The growth of the dendrite may be stopped by removing the voltage and the dendrite may be retracted by reversing the voltage polarity at the anode and cathode. Changes in the length of the dendrite affect the resistance and capacitance of the PMC. The PMC may be incorporated into a variety of technologies such as memory devices, programmable resistor / capacitor devices, optical devices, sensors, and the like. Electrodes additional to the cathode and anode can be provided to serve as outputs or additional outputs of the devices in sensing electrical characteristics which are dependent upon the extent of the dendrite.

Sensor network routing uses distance information of sensors relative to a collector node, optionally along with non-unique key information, to route broadcasts from addressless sensors to a selected addressless collector. Distance calculation messages (DCMs) are used to set distance values on sensors relative to collectors. The distance values enable messages to propagate toward collectors to reduce the number of broadcasts. Self-assigned key information may be added to DCMs propagating in the network to enable routes to be determined through the network without assigning addresses to the participants. By storing the key information associated with the route, and causing sensors to only rebroadcast a message if the message contains a matching key at the matching distance position, broadcast paths may be created on the network. Optionally, diverse collectors and paths may be selected on the network by exchanging traffic condition indications and preferentially selecting paths with better traffic conditions.

A system for increasing the safety of using cellular telephones stores the geographic coordinates of intersections and other traffic features of a local area in a server. The server is interfaced to the cellular telephone network. A programmable GPS enabled telephone handset determines its location upon start-up and transmits that location to through the cellular network to the server. The server responds by transmitting the coordinates of intersections and traffic features surrounding the present location of the telephone handset. As the handset changes location, it determines its new location and compares it to the coordinates provided by the server. If the telephone handset is within a moving vehicle (as determined by the rate of motion of the handset), an audible alarm is issued when the handset comes within a set distance of one of the intersections or traffic features. In this manner a driver speaking on the telephone is alerted before driving into an intersection or other significant traffic feature.

An interferometer scans the sample surface laterally with respect to the optical axis of the interferometric objective. The objective is tilted, so that the sample surface is placed at an angle with respect to the maximum coherence plane of the instrument. By moving the sample stage laterally, at an angle, through a point at a set distance from the objective on the objective's optical axis, rather than vertically along the optical axis, different parts of the object intersect the maximum coherence plane at different times as the surface passes through the coherence plane, the precise time depending on the profile of the surface. When the OPD of a point on the object's surface is greater than the coherence length of the light source, the intensity of light reflected from this point does not produce interference fringes. Therefore, the intensity registered by the detector is approximately constant. However, when the object point enters the zone of coherence, the interference effects modulate the intensity the same way as in a regular VSI procedure. As the object moves along the scanning direction, it also has a relative vertical speed with respect to the objective because of the tilt of the objective's optical axis with respect to the scanning plane; therefore, the lateral scanning motion produces an OPD variation as the vertical scan in a conventional system. As a result, light intensity data are acquired continuously as the test surface is scanned, thus elimination the need for stitching multiple sub-sets of data.

Power to operate the memory card through the second path, when not connected to a host, may also be provided through the external contacts by including a battery in the caps.
