    摘要： A bone oximeter probe includes an elongated member and a sensor head at an end of the elongated member to make measurements for a bone. The measurements can indicate the viability or nonviability of the bone. In an implementation, the probe is advanced through an incision in soft tissue, towards the underlying bone, and positioned so that the sensor head faces the bone to be measured. Optical signals are sent from the sensor head and into the bone. The bone reflects some of the optical signals which are then detected so that measurements for the bone can be made. Some of these measurements include an oxygen saturation level value, and a total hemoglobin concentration value of the bone.

    摘要： A laser module includes a laser source and an optical marshalling module. The laser source is configured to generate and output a plurality of laser beams. The plurality of laser beams have different wavelengths relative to each other. The different wavelengths are distinguishable to an optical data communication system. The optical marshalling module is configured to receive the plurality of laser beams from the laser source and distribute a portion of each of the plurality of laser beams to each of a plurality of optical output ports of the optical marshalling module, such that all of the different wavelengths of the plurality of laser beams are provided to each of the plurality of optical output ports of the optical marshalling module. An optical amplifying module can be included to amplify laser light output from the optical marshalling module and provide the amplified laser light as output from the laser module.

    摘要： According to one embodiment, a magnetic sensor includes a first sensor element and a first interconnect. The first sensor element includes a first magnetic layer, a first opposing magnetic layer, and a first nonmagnetic layer provided between the first magnetic layer and the first opposing magnetic layer. A first magnetization of the first magnetic layer is aligned with a first length direction crossing a first stacking direction from the first magnetic layer toward the first opposing magnetic layer. At least a portion of the first interconnect extends along the first length direction. The first interconnect cross direction crosses the first length direction and is from the first sensor element toward the portion of the first interconnect. A first electrical resistance of the first sensor element changes according to an alternating current flowing in the first interconnect and a sensed magnetic field applied to the first sensor element.

    摘要： Disclosed is a terahertz laser device based on phonon vibration excitation, including a resonant cavity composed of a hollow waveguide made of a composite film and optical lenses at both ends of the waveguide, where M represents nano-metal particles. A zinc oxide mesomorphic microsphere is used herein as a source, symmetric stretching vibration of nanosheets on the zinc oxide microsphere is excited and induced by a laser and is transmitted through elastic and electric coupling among the nanosheets, and a terahertz wave with a frequency of 0.36 THz is radiated by means of phonon vibration; moreover, the zinc oxide mesomorphic microspheres and the nano-metal particles are mixed evenly to produce a strong local electric field a few nanometers nearby a surface of the metal particle by taking advantage of a surface-enhanced Raman effect of the nano-metal particles, a nanocantilever of the ZnO mesomorphic microsphere is greatly changed in polarizability with ample contact of the nano-metal particles and the ZnO mesomorphic microspheres, and thus the terahertz radiation power thereof is enhanced.

    摘要： A slip track includes a continuous circuitous track. The continuous circuitous track includes a layered printed circuit board. The layered printed circuit board includes a top track layer configured to supply electric power to a device having a contact element sliding across the top track layer, the layered printed circuit board further having a lower layer connected to the top track layer, the lower layer configured to supply electric power to the top track layer. The layered printed circuit board is flexible and is bent around curves in the continuous circuitous track. A method of assembly using the slip track is further disclosed.
