  • Publication number: 20100034159
    Abstract: A medium access control (MAC) technique of a multihop sensor network. In the multihop sensor network, the MAC technique may contribute to significantly reducing transmission delay, and allow real-time services to be provided to all nodes by extending a guaranteed time slot (GTS) restricted to one hop in a personal area network (PAN) coordinator (PNC) to all nodes. Furthermore, the MAC technique may allow the number of available GTSs to be significantly increased, by using all 16 frequency band channels instead of using only a single frequency band and setting a multi-superframe.

  • Publication number: 20090147715
    Abstract: Provided is a method of minimizing power consumed by each node in a wireless network when communicating with neighboring nodes. Unlike a conventional synchronous media access control (MAC), the present invention suggests an asynchronous MAC. Thus, the active duration of a node extends only when transmitting a large quantity of data and the extended active duration returns to the minimum active duration again after completing the data transmission.

  • Patent number: 7515265
    Abstract: An optical technique to improve the imaging of a target inside suspensions of scattering particles includes the illumination of the scattering particles with circularly polarized light. The backscattered light from the host medium preserves the helicity of incident light, while the backscattered light reflected from the target is predominated with light of opposite helicity. Based on the observed helicity difference in the emerging light that originated at the target and that backscattered from the medium, the present optical technique improves the image contrast using circular polarization. This approach makes use of polarization memory which leads to the reflected light from the target accompanied by weak diffusive backscattered light. Using the present technique, improved imaging of the artery wall is achieved and plaque composition can be assessed through a blood field associated with the artery.

  • Patent number: 7440480
    Abstract: A method is described to improve and produce purer Cr4+-doped laser materials and lasers with reduced co-incorporation of chromium in any other valence states, such as Cr3+, Cr2+, Cr5+, and Cr6+.

Purer Cr4+-doped laser materials are characterized by a relatively high concentration of Cr4+-lasing ion in crystalline host that makes these materials suitable for compact high power (thin disk/wedge) NIR laser applications.

  • Patent number: 7423254
    Abstract: An optical device for sensing an incident optical wave within a wavelength range includes a first array and a second array of electrodes superposed on a substrate, and a sensor connected to the contacts. The arrays are interdigitated. Each array includes its own parameters: contact width, contact thickness, groove width, and a groove dielectric constant. A structure associated with the arrays resonantly couples the incident wave and a local electromagnetic resonance or hybrid mode including at least a surface plasmon cavity mode (CM). For coupling the CM, an aspect ratio of contact thickness to spacing between electrodes is at least 1. A preferred structure for coupling a hybrid mode for high bandwidth and responsivity includes a higher dielectric constant in alternating grooves. The substrate may include silicon, including silicon-on-insulator (SOI). An SOI device having a alternating grooves with a higher dielectric, e.g., silicon oxide, provides 0.25 A/W and 30 GHz bandwidth.
