    摘要： An apparatus detects changes in water vapor above a cooktop surface and includes a radiation source that is positioned below the cooktop surface. The radiation source emits radiation having a predetermined water vapor absorption wavelength. A beam splitter splits the emitted radiation into a first radiation beam and a second radiation beam. The first radiation beam is directed through and above the cooktop surface. A reflective surface positioned above the cooktop surface reflects the first radiation beam. A radiation sensor detects the reflected first radiation beam and generates a sensor output. A reference radiation sensor receives the second radiation beam from the beam splitter and generates a reference output. A processor is connected to the radiation sensor and the reference radiation sensor and receives the sensor output and the reference output. Changes in water vapor above the cooktop surface are determined by analyzing the sensor output and the reference output.

    摘要： Techniques are provided for using a multi-stage actuator to actuate one or more optical components of an optical head. The multi-stage actuator includes a cross-layer displacement component which actuates an optical component to change the beam focus in a displacement range corresponding to the thickness of the data layers in a holographic disk, such that a beam is impinged on the target data layer. The multi-stage actuator also includes a intra-layer focusing component which actuates the optical component in a smaller range to focus the beam on the target data position. The cross-layer displacement component and the intra-layer focusing component may each include more than one actuator. In some embodiments, the focusing component also actuates the optical component in a tilting motion to compensate for movement or imperfections of the disk during a reading or recording process.

    摘要： Provided are methods and systems of using division-free duplexing (DFD) to reduce rendezvous time between two or more cognitive radio devices. The cognitive radio devices may opportunistically use available frequency spectra by communicating over available channels. To communicate, a first device may rendezvous with a second device by transmitting a beaconing signal over a frequency on which the second device is listening. DFD techniques may enable each of the devices to listen to a channel while concurrently transmitting beacon signals over the same channel. As periods of listening and periods of transmitting over the same channel need not be separated due to the transmitter cancelling approach used in DFD techniques, rendezvous time may be significantly reduced. Further, embodiments include a generalized DFD (GDFD) approach wherein devices listen to a broad band of frequencies, thus further reducing rendezvous time.

    摘要： Techniques are provided for increasing spectral efficiency over data channels in a storage or communication system. In some embodiments, data may be encoded and transmitted over multiple channels. The transmitted data from the multiple channels may be considered together as a channel bundle, thereby increasing the edge transitions of the group of signals to improve clock recovery and reduce coding constraints. In some embodiments, the channel bit size is reduced to maximize data rates based on the reduced coding constraints. Furthermore, the channel bundle has only one channel with timing markers, so that a receiver may receive information from the channel bundle and recover clocking based on the timing markers in the one channel.
