  • Patent number: 11489484
    Abstract: A solar energy harvesting assembly having a unique attachment that can be arranged, mounted, moved and attached to new or existing structures. Solar rings are mounted on any vertical structure that may benefit from solar power using an aesthetically pleasing design that is resistant to wind load. The assembly does not require the need for pitch, azimuth or bearing measurements. The assembly is also capable of energy harvesting from reflected light below with the use of bifacial photovoltaic panels. The mounting design allows the solar energy harvest device to be installed on any vertical structure, including light poles, power poles, parking structures and other minimal load bearing structures. Further, the assembly can be attached to water towers, existing radio towers (guyed, monopole, stealth, self-supporting towers) all used to create vast amounts of unshaded vertical space for solar energy harvesting.

    Abstract: Disclosed herein is a memory cell including a memory element and a selector device. Data may be stored in both the memory element and selector device. The memory cell may be programmed by applying write pulses having different polarities and magnitudes. Different polarities of the write pulses may program different logic states into the selector device. Different magnitudes of the write pulses may program different logic states into the memory element. The memory cell may be read by read pulses all having the same polarity. The logic state of the memory cell may be detected by observing different threshold voltages when the read pulses are applied. The different threshold voltages may be responsive to the different polarities and magnitudes of the write pulses.

    Abstract: To protect memory cards, such as SD type cards, and similar devices from Electrostatic Discharge (ESD), the input pads of the device include points along their edges that are aligned with correspond points on a conductive frame structure mounted adjacent the input pad to form a spark gap. The input pads are connected to a memory controller or other ASIC over signal lines that include a diode located between the input pad and the ASIC and a resistance located between the input pad and the diode. The resistance and diode are selected such that an ESD event at an input pad triggers a discharge across the spark gap before it is transmitted on to the ASIC, while also allowing a high data rate for signals along the signal line.

  • Patent number: 11476789
    Abstract: A system of driving and controlling a motor is provided. A main controller adjusts frequencies of all or some of pulse waves of an initial pulse width modulation signal to output a pulse width modulation signal according to instruction information. The adjusted frequency of each of the pulse waves is equal to a first preset frequency or a second preset frequency. When a motor driver drives the motor to stably rotate, the motor driver decodes each of the pulse waves having the first preset frequency into a first message and decodes each of the pulse waves having the second preset frequency into a second message. The motor driver arranges and combines all of the first messages and the second messages that are decoded from the pulse waves to obtain the instruction information. The motor driver executes an operation instructed by the instruction information.

  • Patent number: 11463036
    Abstract: The disclosure uses the Carter's coefficient to correct the equivalent electromagnetic air gap length. And the specific permeance on both sides of the primary core is obtained. Then, the permeance on both sides based on the structure of the primary core is calculated. An equation is established by using the continuity principle of flux, thereby obtaining the air gap magnetomotive force model of current-carrying conductor. The slot vector diagram of magnetomotive force in short primary linear machine is illustrated according to that in the rotating machine. Then, based on the winding arrangement and vector combination, the amplitude and phase of various spatial harmonic wave of the three-phase winding are obtained. Finally, the characteristics of average component distribution of the current-carrying conductor are adopted to obtain the pulsating magnetomotive force generated by the three-phase winding of the linear machine.
