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.

Abstract: A steerable medical device includes a handle and an elongate shaft extending distally from the handle to a distal tip. A motor control assembly including a motor control housing is configured to detachably interface with the handle. The motor control assembly includes a first drive assembly and a second drive assembly disposed within the motor control housing. The motor control assembly includes an input device and a controller that is operably coupled with the first drive assembly, the second drive assembly and the input device. The controller is configured to control operation of the first drive assembly and/or the second drive assembly in order to move the distal tip, receive one or more user inputs from a user via the input device, and to modify operation of the first drive assembly and/or the second drive assembly in accordance with the received one or more inputs.

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 spectrum management database and server provides measurement and modeling of RF (Radio Frequency) cloud interference in near real-time results for efficient utilization of the precious spectrum. This shared spectrum defines a scarce resource shared among all wireless devices of the universe in frequency, time, and space. Near real-time forecasting of the RF cloud interference is beneficial in pursuit of a path to the optimal utilization of spectrum and a liberated spectrum management. A spectrum management server gathers interference information including bandwidth ranges and locations from a plurality of deployed devices, receives requests for bandwidth, and satisfies the request by allocating a non-interfering bandwidth at a requesting location based on the stored indications

Abstract: Materials and methods for a rapid and effective way to create a carbon negative self-healing construction material are described. The construction material uses sand aggregates, a trace amount of catalyst, a small dosage of scaffolding material with a crosslinking agent, and a calcium source. The curing is performed at a high temperature for a short period or at room temperature for a long period. The catalyst-driven method to bridge the sand particles results in a dense, stiff, strong, and tough structural material, which upon exposure to calcium source and CO2 heals itself repeatably.

Abstract: A Ring-Arrayed Forward-viewing (RAF) ultrasound imaging and administration device combines an ultrasonic (US) US imager including a plurality of single element transducers arranged in a circular frame to define a ring array, and an instrument posture tracking circuit coupled to the ring array for performing RF (radio frequency) data acquisition with the plurality of ring-arrayed transducers. A needle holster is concentrically disposed in the ring array and is adapted to receive and direct an insertion instrument such as a needle, probe or extraction tool along an axis defined by a center of the ring array directed by the concentric needle holster. The tracking circuit includes a processor having instructions for instrument posture tracking and US imaging.

Abstract: A force absorbing device for a footwear appliance includes a shoe upper and a shoe sole having a planar sole surface, such that forces between the shoe upper and planar sole surface in ground contact are absorbed by force mitigation assemblies disposed in the shoe sole. A force mitigation assembly adapted for an athletic shoe includes a linkage to a wearer interface responsive to movement based on activity of the wearer. An attachment to a sole surface receives ground forces transmitted from frictional contact between the sole surface and a surface against which the sole is disposed, such as for running, turning, etc. A force mitigation assembly absorbs these forces received from the sole surface for directing the received force in a controlled manner. An elastic field in the force mitigation assembly is defined by a resilient material adapted to deform in response to the received force.
