  • Patent number: 12345491
    Abstract: An apparatus and methods are provided for a front plate having a diverging central bore for firearm sound suppressors that improves noise and flash characteristics during firing a weapon. The central bore is disposed between a back surface and a front surface of the front plate. An untapered portion of the central bore extends from the back surface to a diverging portion that opens toward the front surface. The diverging portion includes a curvature profile configured to allow for more controlled expansion of high-pressure propellant gases exiting of the suppressor through the central bore. The curvature profile provides an included angle of the central bore that decreases secondary flash events accompanying the expulsion of propellant gases accompanying a fired bullet exiting the suppressor through the central bore. The curvature profile exhibits a cross-sectional area of the central bore that is proportional to a distance along the diverging portion.

  • Patent number: 12314162
    Abstract: Described are integrated circuits for equalizing parallel write-data and address signals from a memory controller. The integrated circuits each include a set of decision-feedback equalizers, one equalizer for each received signal. Each equalizer in a set has a main sampler and a monitor sampler, each of which samples the respective input signal on edges of a timing-reference signal (e.g. a clock or strobe) that is common to the set. The main sampler samples the input signal relative to a reference. The monitor sampler samples the input signal relative to an adjustable threshold calibrated to monitor one or more levels of the input signal. A feedback network adjusts the respective input signal responsive to one or more tap values that can be adjusted to equalize the signal. An adaptive tap-value generator for one or a collection of the equalizers adjusts the tap value or values as a function of least-mean squares of errors to one or more of the sampler input ports.

  • Publication number: 20250102251
    Abstract: An apparatus and methods are provided for a cam race for improving the longevity of an upper receiver of a direct gas operated firearm. The cam race provides a hardened slide face and a corner surface for a cam pin comprising a bolt carrier group of the firearm. The cam race is configured to be secured into a window disposed in the upper receiver. The window is surrounded by a counterbored area that receives a back plate of the cam race. The counterbored area and the thickness of the back plate cooperate such that the corner surface and the slide face are positioned to receive the cam pin during reciprocal movement of a bolt carrier group within the upper receiver. The cam race is retained in the upper receiver by fasteners that are tightened into threaded holes in the counterbored area.

  • Publication number: 20250102254
    Abstract: An apparatus and methods are provided for a cartridge extractor to improve the longevity and safety of direct gas operated firearms. The extractor comprises an elongate body having a first end and a second end. The first end comprises a claw portion that grips a rim of an ammunition cartridge. The extractor includes a lug and an elongated rib that reinforce the claw portion. The second end comprises a biased portion that ensures that the rim of the cartridge casing remains within a notch comprising the claw portion until the cartridge casing is ejected from the firearm. A pivot portion is disposed between the first end and the second end. The pivot portion couples the extractor with a bolt and presses the claw portion into a forward recess of the bolt due to spring forces acting on the biased portion.

  • Publication number: 20250036187
    Abstract: The disclosed embodiments relate to a system that supports dynamic bursts to facilitate frequency-agile communication between a memory controller and a memory device. During operation, the system monitors a reference clock signal received at an interface between the memory device and the memory controller. Upon detecting a frequency change in the reference clock signal from a fullrate to a subrate, the interface operates in a burst mode, wherein data is communicated through bursts separated by intervening low-power intervals during which portions of the interface are powered down.

  • Patent number: 11854366
    Abstract: The present disclosure provides a leak monitoring system and associated method which is being configured to detect plumes of volatile organic compounds (VOC) as an alternative solution to the EPA Method 21, which measures VOC concentrations at the surface of each component. The leak monitoring system is a multi-layered system that includes monitoring performed by sensors that are fixed in place and sensors that are mobile. Each monitoring method is a layer and it complements and augments other layers. All the sensors wirelessly communicate with a central control through a gateway. The control unit further includes a software platform, which analyzes the data provided by the sensors in combination with other informetrics such as meteorological conditions and plant info to both identify the presence of a gas leak and to pinpoint a general location of the gas leak.

  • Publication number: 20230349651
    Abstract: An apparatus and methods are provided for a gas regulator valve for adjusting cycle speeds of direct gas impingement operated firearms. The gas regulator valve comprises a gas inlet for receiving expanding gases from a fired cartridge and a gas tube for directing the expanding gases to a bolt carrier comprising a firearm. The gas inlet is disposed at the front of an upper receiver comprising the firearm. The gas tube directs the expanding gases into a carrier key of the bolt carrier. The gas regulator valve includes a plug for controlling gas flow through the gas tube. An actuator disposed on a side of the upper receiver enables operating the plug. The actuator enables a practitioner to adjust the flow of expanding gases without moving the firearm out of a shooting position. The actuator includes a key that may be turned by a rim of an ammunition cartridge.

  • Publication number: 20230021170
    Abstract: An apparatus and methods are provided for a suppressor to be coupled with a muzzle end of a barrel of a firearm to reduce muzzle blast and muzzle flash. The suppressor comprises a housing having a proximal end and a distal end. A front portion within the housing comprises a series of cylindrical gas expansion chambers for attenuating the temperature and energy of propellant gases accompanying a projectile fired from the firearm. An annular gas expansion chamber surrounds the cylindrical gas expansion chambers and directs a portion of the propellant gases from a rear portion of the suppressor to peripheral vents disposed at the distal end. Lateral chambers within the rear portion deflect and rebound a portion of the propellant gases before passing them into the annular gas expansion chamber. Ledges within the annular gas expansion chamber direct the propellant gases distally through suppressor toward the peripheral vents.

  • Patent number: 10840920
    Abstract: A low-power, high-performance source-synchronous chip interface which provides rapid turn-on and facilitates high signaling rates between a transmitter and a receiver located on different chips is described in various embodiments. Some embodiments of the chip interface include, among others: a segmented “fast turn-on” bias circuit to reduce power supply ringing during the rapid power-on process; current mode logic clock buffers in a clock path of the chip interface to further reduce the effect of power supply ringing; a multiplying injection-locked oscillator (MILO) clock generator to generate higher frequency clock signals from a reference clock; a digitally controlled delay line which can be inserted in the clock path to mitigate deterministic jitter caused by the MILO clock generator; and circuits for periodically re-evaluating whether it is safe to retime transmit data signals in the reference clock domain directly with the faster clock signals.
