Systems and methods for optically pumping alkali-metal atoms using Coherence Population Trapping (CPT) resonances are disclosed. An illustrative push-pull optical pumping system for inducing CPT resonances in a resonance cell containing an admixture of alkali-metal atoms and one or more buffer gasses may include a laser assembly adapted to produce alternating orthogonally polarized light, and at least one DC current source adapted to output a constant-intensity carrier current signal for inducing laser emission from the laser assembly at a carrier wavelength of the alkali-metal atoms. An RF modulated signal outputted from an RF modulation source can be rectified, split, and phase-shifted for inducing a time-dependent polarization of the laser light that can be used to enhance CPT resonances. The alternating orthogonally polarized light from the laser assembly can then be used to optically pump the alkali-metal atoms within the vapor cavity, producing a dark state that can be detected with a photodetector or the like.

A method of testing the electrical functionality of an optically controlled switch in a reconfigurable antenna is provided. The method includes configuring one or more conductive paths between one or more feed points and one or more test point with switches in the reconfigurable antenna. Applying one or more test signals to the one or more feed points. Monitoring the one or more test points in response to the one or more test signals and determining the functionality of the switch based upon the monitoring of the one or more test points.

A security access system performing identification, verification and authorization is provided. In one embodiment, a security access system is disclosed. The security access system comprises, a radio frequency identification (RFID) activator loop integrated in an access road, a loop reactance sensing circuit, an RFID personal identification tag, an imaging device and a verification system. The loop reactance sensing circuit is adapted to measure the reactance of the RFID activator loop to determine the presence of a vehicle. The RFID personal identification tag is adapted to transmit identification data regarding the person it is associated with in response to the RFID activator loop. The imaging device is adapted to record an image of the person. The verification system is adapted to process the identification data of the RFID identification tag and produce an image of the person from a database associated with the identification data.

A method and system for improving sensitivity of microwave and millimeter phase discriminators is disclosed. An exemplary embodiment of a phase discriminator includes two mixers inserted between two 90 degree hybrids. One hybrid splits the reference or LO signal into two signals of equal magnitude with a phase difference of 90 degrees. Similarly, the other hybrid splits the received RF signal into equal signals shifted 90 degrees in phase. One mixer receives an input set (e.g., LO and RF signals) with a zero-degree phase shift, and the other mixer receives the input set shifted in phase by 90 degrees. Thus, the leakage signals at the output of each mixer have the same magnitude but are 180 degrees apart in phase. The IF ports of the mixers are tied together, allowing the leakage signals of the mixers to combine destructively, thereby increasing isolation and sensitivity.

A connection made between components at a safe temperature for each of the components. A slot made may be provided on one component and a tab provided on the other component. The slot may be filled with an electrically conductive material. The tab may be inserted in the slot before significant curing of the material and kept in the slot throughout the curing period of the material. The curing may be effected at a temperature harmless to the components. For example, the temperature may be room temperature. One example of a temperature-sensitive component may be a thin battery.

In general, the disclosure is directed to techniques for determining the position of a piston within a linear actuator, such as a hydraulic cylinder, in a more cost effective and less labor-intensive fashion compared to current techniques for determining the position of a piston within a linear actuator. One or more magnets may be operably coupled to the piston, and a linear array of sensors may be disposed along an exterior length of the linear actuator. The sensors may measure the magnetic field generated by the magnet and, based on the measured magnetic field, may determine the location of the piston within the linear actuator.

Techniques are described for sensing a position of an object located within an enclosure over a position range. The techniques include generating an expected output signal of each of a plurality of magnetic field sensors disposed along an outer surface of the enclosure, receiving actual output signals from the sensors, wherein each actual output signal indicates a relative proximity of a magnetic target coupled to the object to the corresponding sensor. The techniques further include superimposing the expected output signal over the actual output signals, and iteratively shifting the expected output signal over position relative to the actual output signals and comparing the shifted expected output signal to the actual output signals, until the expected output signal compared to the actual output signals corresponds to a substantially minimized error parameter. The position of the object may then be determined based at least in part on the shifted expected output signal.
