  • Patent number: 10433614
    Abstract: Disclosed are improved designs for incorporating static dissipative qualities into footwear. A novel static dissipative shoe may be made by incorporating a conductive layer or element that spans the exposed side surface of the sole on the outside of the finished shoe, in at least one location along the perimeter of the sole. A unique advantage is that static dissipative qualities may be incorporated into many existing shoe designs with no tooling changes, by adding a step to the manufacturing process, such as a pad printing step, for instance. Another advantage is that static dissipative qualities may be included at a lower cost, because fewer conductive parts and less conductive material are required, as compared to prior art. Yet another advantage is that, unlike for prior art, most embodiments have a negligible effect upon basic shoe performance characteristics, such as shock absorption, support, or wear resistance.

  • Patent number: 10424907
    Abstract: An electrical junction box has a switch connected between a first connection terminal and a second connection terminal to which a fuse is mounted, and a control circuit configured to perform opening/closing control of the switch, has a storage unit for storing a standard resistance value in an initial state of the fuse and an amount of change in a resistance value of the fuse over time, and detects a first terminal voltage at the first connection terminal and a second terminal voltage at the second connection terminal. The control circuit opens the switch at a time of startup based on a control signal, calculates the resistance value of the fuse, calculates a reference resistance value, determines whether the fuse is correct by comparing the calculated resistance value of the fuse with the calculated reference resistance value, and outputs a first error signal if the fuse is incorrect.

  • Patent number: 10415896
    Abstract: Systems according to the present disclosure provide one or more surfaces that function as heat or power radiating surfaces for which at least a portion of the radiating surface includes or is composed of “fractal cells” placed sufficiently closed close together to one another so that a surface (plasmonic) wave causes near replication of current present in one fractal cell in an adjacent fractal cell. A fractal of such a fractal cell can be of any suitable fractal shape and may have two or more iterations. The fractal cells may lie on a flat or curved sheet or layer and be composed in layers for wide bandwidth or multibandwidth transmission. The area of a surface and its number of fractals determines the gain relative to a single fractal cell. The boundary edges of the surface may be terminated resistively so as to not degrade the cell performance at the edges.

  • Patent number: 10394575
    Abstract: An automatic hold switch is disclosed. The automatic hold switch provides a means for automatically switching a hold feature on and off. When the hold feature is on, one or more input devices of a portable electronic device are disabled or prevented from providing input signals. When the hold feature is off, one or more input devices of a portable electronic device are enabled or allowed to provide input signals. Because the user no longer has to manually control the hold feature, the number of actions that need to be taken by the user is reduced. In one example, the automatic hold switch is embodied with light sensors that detect when the device is in a dark environment and when the device is in a light environment. A dark environment indicates to the portable electronic device that the user wishes not to input and therefore the hold feature is turned on. A lighted environment indicates to the portable electronic device that the user wishes to input and therefore the hold feature is turned off.

  • Patent number: 10354994
    Abstract: Aspects disclosed herein include electrostatic discharge (ESD) protection in an electronic switching circuit. An electronic switching circuit includes switching circuitry configured to provide interconnectivity between a common port in at least one common branch and an input/output (I/O) port in at least one I/O branch. The common branch and the I/O branch each include a blocking capacitor element that is inherently incapable for ESD discharging. As such, an ESD clamp is disposed in parallel to the blocking capacitor element to provide a low-impedance ESD discharging path around the blocking capacitor element. By disposing the ESD clamp in parallel to the blocking capacitor element, it is possible to minimize detrimental parasitic effects of the ESD clamp, thus improving performance and reliability of the electronic switching circuit, especially for high power switching circuits such as a radio frequency (RF) switching circuits.
