  • Patent number: 10878996
    Abstract: Power and/or data are transmitted through variable magnetic fields between a first transceiver coil on a transceiver apparatus and a second transceiver coil in an inductor integrated into a multilevel wiring structure on a semiconductor integrated circuit chip. The first transceiver apparatus generates magnetic fields and can transmit data by varying a characteristic of the magnetic fields. The second transceiver coil receives the power from and/or detects data in the magnetic fields from the first transceiver apparatus. The inductor can include a ferromagnetic core that concentrates magnetic flux to improve data or power transmission efficiency to miniaturize the second transceiver coil while maintaining adequate inductive coupling between the coils. The second transceiver coil can transmit data by varying the impedance of the inductor and/or the integrated circuit. The semiconductor integrated circuit chip can be coupled to an object and the second transceiver coil can transmit data relating to the object.

  • Publication number: 20200360179
    Abstract: A means can be used instead of or with conventional temperature control to achieve warming device temperature control at a lower cost, prevent or reduce deterioration of a warming device over time, and lower generated heat temperature due to storage at high temperatures. The warming device can be used for the same. A higher level temperature control means can be used for warming devices for medical applications. An improved warming device can be used for medical applications with a high level of safety and efficacy. A temperature control agent controls a maximum temperature of a warming device with a heat generating composition that generates heat by reaction with oxygen. Said agent includes an aliphatic compound that has a particle form that will not pass through a standard sieve with a #60 mesh, a melting point of 35-65° C., and an aqueous solubility (g/100 mL) at 20° C. of ?5.

  • Patent number: 10431371
    Abstract: A method of forming an inductor assembly includes depositing a magnetic core on a planar substrate lying in a core plane, forming an inductor coil that generates a magnetic field that passes through the magnetic core in a closed loop parallel to the core plane, and annealing the magnetic core while applying an external magnetic field that passes through the magnetic core in a radial direction to permanently fix the easy axis of magnetization parallel to the radial direction. As a result, the hard axis of magnetization of the magnetic core is permanently oriented in a generally circular closed path parallel to the closed loop of the inductor's magnetic field.

  • Patent number: 10326366
    Abstract: A switched-mode power converter includes timing control feedback loop circuits to minimize or eliminate the potential difference across a high-power switch and a low-power switch during their transitions times. A first feedback circuit compares the measured voltage across the high-power switch at the moment the high-power switch closes with the input voltage to the high-power switch to control a low-to-high delay time. A second feedback circuit compares the measured voltage across the low-power switch at the moment the low-power switch closes with the input voltage to the low-power switch to control a high-to-low delay time. A third feedback circuit compares the measured voltage across the low-power switch at the moment the low-power switch opens. The output of the third feedback circuit is provided as inputs to the first and second feedback circuits. The third feedback circuit also controls the frequency of the power converter.
