  • Publication number: 20180188952
    Abstract: Provided are an apparatus, system and method for apparatus, system and method for throttling an acceptance rate for adding host Input/Output (I/O) commands to a buffer in a non-volatile memory storage device. Information is maintained on an input rate at which I/O commands are being added to the buffer and information is maintained on an output rate at which I/O commands are processed from the buffer to apply to execute against the non-volatile memory. A determination is made of a current level of available space in the buffer and an acceptance rate at which I/O commands are added to the buffer from the host system to process based on the input rate, the output rate, the current level of available space, and an available space threshold for the buffer to maintain the buffer at the available space threshold. I/O commands are added to the buffer to process based on the acceptance rate. The I/O commands are accessed from the buffer to process to execute against the non-volatile memory.

  • Patent number: 9998117
    Abstract: A resettable solid state fuse that automatically restores an interrupted circuit after an overcurrent event is cleared. The resettable solid state fuse can include one or more switching devices, such as, for example, a normally-on power semiconductor, and one or more positive temperature coefficient (PTC) resistive elements. The switching device is structured to extend the voltage rating of the resettable fuse, allowing the solid state resettable fuse to attain both a relatively elevated voltage rating and a relatively elevated electrical current rating while using a PTC resistive element. According to certain embodiments, the solid state resettable fuse can be tripped by a cascaded PTC resistive element, thereby providing a passive electronic device that can operate in the absence of electronic sensing, detection, and tripping, as well as without reliance on an auxiliary power supply.

  • Patent number: 9953233
    Abstract: A method of determining whether a biometric object is part of a live individual is described. In one such method, image information is acquired from the biometric object by using a sensor, such as an ultrasonic sensor. The image information may be analyzed in at least two analysis stages. One of the analysis stages may be a temporal analysis stage that analyzes changes in the image information obtained during a time period throughout which the biometric object was continuously available to the sensor. For example, a dead/alive stage may analyze differences between image information taken at two different times in order to identify changes from one time to the next. Other stages may focus on aspects of a particular image information set, rather than seeking to assess changes over time. These other stages seek to determine whether an image information set exhibits characteristics similar to those of a live biometric object.

  • Patent number: 9666977
    Abstract: Technologies for providing DC arc protection in a DC socket include an electromagnet positioned in the DC socket configured to produce a magnetic field. The electromagnet is positioned to be adjacent to a contact region between one or more supply terminals of a DC socket and one or more prongs of a DC plug. As the DC plug is disconnected from the DC socket, a DC arc might form between one or more of the supply terminals and one or more of the prongs. The magnetic field produced by the electromagnet reduces the energy of the DC arc and reduces the time duration of the DC arc.
