Abstract: A sensor system for diffuse reflectance tissue monitoring, the sensor system comprising: one or more integrated photonic silicon or silicon nitride broadband transceiver circuits for multi-wavelength diffuse reflectance tissue monitoring, wherein the one or more transceiver circuits includes a transmitter photonic integrated circuit (PIC), the transmitter PIC comprising an optical phased array (OP A) the OP A comprising a steering mechanism to steer transmitted light across the tissue.

Abstract: Virtual disk drive architecture. A novel approach is presented by which a virtual design system allows for the design, development, and testing of memory storage devices including hard disk drives (HDDs). A virtual disk drive architecture allows for the implementation and emulation of a full HDD system. All of the pieces of the HDD system (e.g., including both the read channel and the controller functionalities) are included and implemented to allow a designer to develop and test certain portions within the system. In some embodiments, one or more field programmable gate arrays (FPGAs) are employed to implement a hard drive (HD) controller in an all digital implementation. Various combinations including circuit boards and FPGAs can be employed to emulate an entire HDD system. In even other embodiments, one or more sockets, and appropriate interfacing, are included to allow the testing of actual chips within the virtual disk drive architecture.

Abstract: An ISDN or other enhanced bulk delivery telephone signal i processed by a channel bank receiver to preferrably produced a plain old telephone signal output having dialed number and caller I.D. as lead information. This signal is advantageously used by a security station receiver to distinguish different calling alarm panels which may not be uniquely identified by their own address. This information also allows more effective processing of telephone signals received by the security station.
