摘要： An optical signal modulator (modulator) includes, in part, a first multitude of diodes coupled in parallel and disposed along an outer periphery of the optical ring of the modulator, a second multitude of diodes coupled in parallel and disposed along the outer periphery of the optical ring, and a doped region adapted to supply heat to the optical ring. A pair of current sources supply substantially constant currents to the first and second multitude of diodes to generate a pair of electrical signals. The modulator further includes, in part, a control circuit adapted to control the temperature of the optical ring in accordance with the pair electrical signals. To achieve this, the control circuit varies the voltage applied to the doped region to vary the supplied heat. Alternatively, the control circuit applies a voltage to the optical ring to maintain a substantially constant resonant wavelength in the optical ring.

摘要： A magnetic spectrometer is integrated in a semiconductor substrate and provides high sensitivity without using an external magnet field. The spectrometer includes one or more highly stable on-chip oscillator and LC resonator. A current caused to pass through the inductor generates a magnetic field and polarizes the nanoparticles placed in its proximity, thereby changing the effective inductance of the inductor, and in turn, modifying the oscillation frequency of the LC resonator. The shift in the oscillation frequency is used to characterize the nanoparticles and measure their magnetic susceptibility frequency profile. The spectrometer operates at multiple frequencies over a diverse range without using a reference sensor thereby effectively increasing its spatial multiplexing density. The magnetic spectrometer uses the relationship between the sizes of the particles and the resonance frequency Fres and/or the magnetic frequency spectrum of the particles as a spectroscopic means of differentiating between the particles.

摘要： A camera includes, in part, an optical signal source generating a frequency varying optical signal, a multitude of pixels arranged along rows and columns, an optical focusing element, and an opto-electronic circuit. A portion of the optical signal generated by the optical signal is caused to reflect from a target object and then directed toward the pixels. A multitude of samples of a second portion of the optical signal are combined with the signals received by the pixels to generate a multitude of combined optical signals. The optical signals so combined are converted to electrical signals. Each electrical signal has a frequency defined by a difference between a frequency of the second portion of the optical signal and a frequency of a signal received from a pixel. The frequency differences are used to form an image of the target object.

摘要： A multi-port radiator radiates electromagnetic signal in response to a beat frequency of a pair of optical signals. The radiator includes a multitude of optical paths each carrying an optical signal having first and second wavelengths. A multitude of frequency conversion elements convert the optical signals to electrical signals and deliver them to the radiator's multiple ports. The frequency of the electrical signals, and hence the frequency of the electromagnetic wave, is defined by the difference between the first and second wavelengths. The phases of the optical signals received by the frequency conversion elements are shifted with respect to one another. Optionally, the difference between the phases of the optical signals travelling through each pair of adjacent paths is 90. The first and second wavelengths are generated by a pair of optical sources and are optionally modulated before being combined and delivered to the optical paths.

摘要： Systems and processes for determining a contextual status of a resource, such as a user, using a contextual presence framework are described. A plurality of modes may be associated with the resource, where each mode represents a context of the resource. A presence value of the resource may be determined for each mode, which represents the extent to which the resource is engaged in the mode. An availability value of the resource may be determined for each mode, which represents the extent to which the resource is willing to be interrupted in the mode. A contextual presence status summary having a status summary availability value and a status summary presence value may be determined based on, for example, a weighted average of the presence values and a weighted average of the availability values of multiple modes of the resource.

摘要： An optical phased array includes, in part, a multitude of optical signal emitters and a multitude of optical signal phase/delay elements each associated with and disposed between a different pair of the optical signal emitters. Each optical signal phase/delay element is adapted to cause a phase/delay shift between the optical signals emitted from its associated pair of optical signal emitters. Each optical signal phase/delay element is optically a ring resonator that includes a p-i-n junction. By varying the bias applied to the p-i-n junction, the phase/delay generated by the ring resonator is varied. Furthermore, each optical signal emitter is optionally an optical grating having a multitude of grooves. The groove lengths of the optical gratings are optionally selected so as to increase along the direction of travel of the input optical signal through the optical phase array.

摘要： A device for descrambling encrypted data includes a descrambler, a secure link, and a secure element that securely transmits a control word to the descrambler in a normal operating mode. The secure element includes a first secure register, a read-only memory having a boot code, a random-access memory for storing a firmware image from an external memory, and a processor coupled to the first secure register, the read-only memory, and the random access memory. The processor executes the boot code to generate the control word, stores the control word in the first secure register, and send the stored control word to the descrambler through a secure communication link. The descrambler may include a second secure register that is connected to the first secure register through the secure link. The first and second secure registers are not scannable during a normal operation. The secure link contains buried signal traces.
