  • Patent number: 10896613
    Abstract: A method for finding a distressed vehicle operated by a first user located in an urban area includes providing a first mobile device of a first user. The first mobile device is electronically connected to a wireless communication network, and the first user is in possession of a vehicle. An event is detected that has occurred to the vehicle and a severity level of the event. When the severity level of the event is above a threshold it is determine that the event was sufficient enough to warrant an emergency response. A current position is determined of the first mobile device of the first user. A second mobile device of a second user is searched for within a first distance of the current position of the first mobile device. A first notification is communicated to the second user via the second mobile device.

  • Patent number: 10895145
    Abstract: A boring tool that is moved by a drill string to form an underground bore. A transmitter transmits a time varying dipole field as a homing field from the boring tool. A pitch sensor detects a pitch orientation of the boring tool. A homing receiver is positionable at a target location for detecting the homing field to produce a set of flux measurements. A processing arrangement uses the pitch orientation and flux measurements with a determined length of the drill string to determine a vertical homing command for use in controlling depth in directing the boring tool to the target location such that the vertical homing command is generated with a particular accuracy at a given range between the transmitter and the homing receiver and which would otherwise be generated with the particular accuracy for a standard range, different from the particular range. An associated system and method are described.

  • Publication number: 20210010828
    Abstract: A device rotates at least one static magnetic field about an axis, producing a rotating magnetic dipole field, and is movable in relation to the surface of the ground. The field is periodically sensed using a receiver to produce a receiver output responsive to the field. A positional relationship between the receiver and the device is monitored using the output. In one aspect, changing the positional relationship, by moving the device nearer to a boring tool which supports the receiver, causes an increase in accuracy of depth determination. In another aspect, determination of an actual overhead position of the boring tool, and its application, are described. Use of a plurality of measurements over at least one-half revolution of each magnet is disclosed. Establishing a surface radial direction toward a boring tool and resolution of multi-valued parameters is described. Calibration techniques, as well as a three transmitter configuration are also described.

  • Patent number: 10879371
    Abstract: Embodiments described in this disclosure relate to formation of a gate structure of a device, such as in a replacement gate process, and the device formed thereby. In some examples, after an interfacial layer and a gate dielectric layer are deposited, a rapid anneal process, such as laser anneal or flash lamp anneal process, is performed in a controlled ambient nitrogen-containing environment to form a nitrided portion in the gate dielectric layer. The nitrided portion passivates the defects at the surface of the gate dielectric layer and can serve as a barrier to prevent etchant chemistry and defects/dopants from the subsequent gate stack layers from affecting or diffusing through the gate dielectric layer. Particularly, the rapid anneal process is performed on a millisecond scale to confine nitrogen atoms in the gate dielectric layer without diffusing into the underlying interfacial dielectric and/or any neighboring structure such as fin.

  • Patent number: 10875061
    Abstract: A fume extraction apparatus having an outer conduit with a first elongated open area extending at a first angle and an inner conduit configured for connection to a venting system and received within the outer conduit. The conduits are rotatable relative to one another. The inner conduit has a second elongated open area extending at a second angle different from the first angle. Overlapping portions of the open areas defines an extraction aperture providing a fluid communication between an environment of the outer conduit and an interior of the inner conduit. Different relative orientations of the conduits define different positions of the extraction aperture, so that the extraction aperture is movable upon relative rotation of the inner and outer conduits. A method of extracting fumes during operation of a laser head is also discussed.

  • Patent number: 10877511
    Abstract: A memory system in which a timing drift that would occur in distribution of a first timing signal for data transport in a memory device is determined by measuring the actual phase delays occurring in a second timing signal that has a frequency lower than that of the first timing signal and is distributed in one or more circuits mimicking the drift characteristics of at least a portion of distribution of the first timing signal. The actual phase delays are determined in the memory device and provided to a memory controller so that the phases of the timing signals used for data transport may be adjusted based on the determined timing drift.

  • Patent number: 10874146
    Abstract: A heat-not-burn tobacco-type device for heating a cigarette has a heater and a vaporizer. The heater heats the cigarette at a heating temperature not greater than 450° C. for discouraging formation of harmful substances, such as tar and carbon monoxide, during heating the cigarette. The vaporizer is used to vaporize a liquid for producing smoke and/or for enhancing a taste of the cigarette. The vaporizer and the heater are arranged to work simultaneously or independently to generate two bodies of aerosol, wherein these two bodies of aerosol pass through two independent gas channels and meet together for a smoker to inhale thereafter. Hence, the device not only meets visual needs of the smoker in the smoke and/or enhances the taste of the cigarette, but also discourages generation of the harmful substance.
