Abstract: A storage and monitoring device for red blood samples in storage for donation (blood bank) and research. Stored blood can be susceptible to degradation, most often from a phenomenon known as ice nucleation. Accurate detection and identification of relevant factors causing ice nucleation can determine healthy samples of stored blood, and identify storage factors that promote storage longevity. A photodetection approach directs an illumination source and photometer on opposed sides of a blood containing vessel for measuring an illuminance affected by hemoglobin released from ruptured cells. Hemoglobin released from ruptured cells reduces light passage though the sample to indicate unusable samples. An accelerometer and temperature sensor measure the physical and temperate factors correlating with the detected cell degradation to determine storage criteria for extending blood longevity.

Abstract: A strain gauge device employs a reflective base adapted to reflect a divergent optical signal, and a glass tube attached to the reflective base for optical communication therewith, the glass tube having a working length into which an optical fiber is inserted. The optical fiber is configured for transporting an optic signal indicative of the detected strain. The optic fiber has an outside diameter slightly smaller than an inside diameter of the glass tube for providing a slight tolerance. A distal end is disposed in slidable communication with an interior of the glass tube and accommodated by the tolerance, and a sensing circuit at the proximate end receives an optical signal indicative of strain or displacement. A resilient buffer layer made of soft silicone is disposed outside the glass tube to allow for large deformation measurements and reduce the distortion of the deformation by the introduction of the sensor.

Abstract: Cathode material from exhausted lithium ion batteries are dissolved in a solution for extracting the useful elements Co (cobalt), Ni (nickel), Al (Aluminum) and Mn (manganese) to produce active cathode materials for new batteries. The solution includes compounds of desirable materials such as cobalt, nickel, aluminum and manganese dissolved as compounds from the exhausted cathode material of spent cells. Depending on a desired proportion, or ratio, of the desired materials, raw materials are added to the solution to achieve the desired ratio of the commingled compounds for the recycled cathode material for new cells. The desired materials precipitate out of solution without extensive heating or separation of the desired materials into individual compounds or elements. The resulting active cathode material has the predetermined ratio for use in new cells, and avoids high heat typically required to separate the useful elements because the desired materials remain commingled in solution.

Abstract: A nozzle apparatus for a 3D printer employs a center post or shape and extrudes a circumferential, tubular form having a central void. The nozzle includes a radial arrangement of prongs or supports around a center post, which provides space for molten print medium to flow in a 360° form around the center post. The nozzle extrudes a hollow tubular form around the post that can lay a tube shaped article on a perpendicular print bed, or can be used to deposit high resolution, hollow cylindrical segments for forming lightweight articles with less volume of print medium required due to the hollow extruded shape. A stream of air or gas may be emitted into the center of the extrusion for maintaining a tubular shape. Other suitable shapes may be employed by altering the contour of the center post and the bore.

Abstract: A method for detecting physical attacks on a computing device includes embedding a sensor or FPGA (Field Programmable Gate Array) on a circuit board for gathering a frequency response of a power distribution network providing power to the circuit board. During operation of the circuit board, the sensor identifies and gathers a frequency response suspected of resulting from a tamper effort, and compares the identified frequency response to a frequency response of tempering events. Based on the comparison, a determination of tampering is made.

Abstract: A recycling and synthesis of charge material for secondary batteries generates single-crystal charge materials for producing batteries with greater charge cycle longevity. Charge material particles undergo a heating for fusing or enhancing grain boundaries between polycrystalline particles. The resulting, more well-defined grain boundaries are easily etched by a relatively weak mineral acid solution. The acid solution removes material at the grain boundaries to separate secondary particles into primary particles along the grain boundaries. The resulting single crystal (monocrystalline) charge material particles are washed and filtered, and typically re-sintered to accommodate any needed lithium (lithium carbonate), and result in a charge material with larger surface area, higher lithium diffusivity and lower cation ordering.
