  • Patent number: 10812130
    Abstract: Examples of backscatter systems, device, and techniques are described herein. Example backscatter devices may utilize CSS modulation to provide backscatter signals including CSS signals (e.g., LoRa packets). Utilizing CSS modulation may advantageously allow for backscatter communication over wide areas. Examples of backscatter devices described herein may toggle the impedance of the backscatter device between multiple (e.g., eight) impedances to reduce and/or eliminate higher order harmonic components in the backscatter signal (e.g., third and fifth harmonic components).

  • Publication number: 20200316239
    Abstract: A system and methods for sterilizing and drying contaminated articles, particularly medical articles, and more particularly the hollow internal areas of medical instruments or lumens of medical endoscopes. The system includes a plasma generator having an electrode, a shield, and a dielectric gap between the electrode and the shield. A source of electrical power connected to the plasma generator applies an electrode energy density between the electrode and the shield. A source of a sterilizing gas precursor provides a flow of the sterilizing gas precursor through the plasma generator to generate a plasma, thereby forming a sterilizing gas including acidic and/or oxidizing species. The contaminated article is exposed to the sterilizing gas for a time sufficient to achieve a desired degree of sterilization. A turbulent flow of a drying gas is used to dry the contaminated article alternately with the exposure of the contaminated article to the sterilizing gas.

  • Patent number: 10725928
    Abstract: A system and method for efficiently performing maintenance on a cache. In various embodiments, control logic in a cache controller or elsewhere receives an indication for invalidating a range of virtual-to-physical mappings in a given translation lookaside buffer (TLB). The logic determines a first latency to invalidate entries of the TLB based on a number of addresses in the range and a number of supported page sizes simultaneously stored in the TLB. The logic determines a second latency based on a number of entries in the TLB. If the first latency is greater, then the logic traverses through each TLB entry and invalidates TLB entries storing a virtual address within the range. If the first latency is smaller, then the logic traverses through each address in the range and invalidates TLB entries storing a virtual address within the range.

The anvil is rotatable between a first position and a second position. The closure member is slideable along the outer surface to hold the anvil in the second position. The closure member comprises a clearance opening. The staple cartridge is positioned within the staple cartridge carrier. The staple cartridge comprises staples removably stored therein. The staple cartridge and the anvil define a tissue gap therebetween when the anvil is in the second position. The clearance opening is aligned with the tissue gap when the anvil is in the second position. The firing system is configured to eject the staples from the staple cartridge during a staple firing stroke. The firing system engages the staple cartridge carrier and the anvil during the staple firing stroke.

  • Publication number: 20200152173
    Abstract: A method improves a functionality of a conversational agent that is generated by an artificial intelligence (AI) system. A conversational agent receives a first utterance from a first entity. The AI system identifies an unverified response to the first utterance; sends the unverified response to the first entity; and receives a positive feedback indication about the unverified response from the first entity. The AI system searches a data store in order to identify an entry for a second utterance by a second entity, where the second entity has sent a positive feedback for the unverified response. The AI system sends the second utterance and the unverified response to the first entity, and receives a positive feedback for the unverified response to the second utterance from the first entity in order to mark the unverified response as a verified response, which responds to future receipts of the first utterance.

  • Patent number: 10606256
    Abstract: A method to prevent parasitic current drain of a vehicle battery includes shutting off the vehicle ignition to initiate a power down sequence of electronic control units, and detecting an excessive current draw condition from the vehicle battery after the vehicle ignition is shut off for a predetermined period of time. After verifying that an excessive current draw condition exists by analyzing data collected from the vehicle, the method continues with powering up the electronic control units on a vehicle communications network and broadcasting a system state equals run, and broadcasting a system state equals off on the vehicle communications network after the electronic control units have reached steady state operation.

  • Publication number: 20200091768
    Abstract: A wireless power transfer system includes a transmitter configured to transmit power to a receiver, for example, through coupled resonators. The transmitter receives feedback from the receiver, and uses the feedback to control the power transmission, to control a parameter at the receiver, for example, a rectified voltage output by the receiver. The feedback to the transmitter may be provided, for example, by an out-of-band radio system between the transmitter and receiver, by a reflection coefficient at the transmitter, and/or by an encoded modulation of power in the receiver, for example, in an impedance matching module. The transmitter may control the transmitted power, for example, by controlling a transmitter signal generator voltage (VSiG), a transmitter gate driver voltage (VGD), a transmitter amplifier voltage (VPA), and/or an impedance setting in a transmitter impedance matching module.

  • Patent number: 10587445
    Abstract: Apparatuses, systems, ambient RF backscatter transceivers, and methods for communicating using MIMO and spread spectrum coding of backscattered ambient RF signals are described. An example system may include an ambient RF backscatter transceiver that include an antenna configured to receive a backscattered ambient radio frequency (RF) signal, and a receiver coupled to the antenna. The receiver may be configured to demodulate the backscattered ambient RF signal using one of multiple input, multiple output multiplexing demodulation or spread spectrum code demodulation to retrieve the first data. The backscattered ambient RF signal may be generated by backscattering an ambient RF signal at a first frequency. The ambient RF signal may be configured to provide other data at a second frequency.
