  • Publication number: 20190293144
    Abstract: A damper system for a vehicle is provided that includes a pressure tube and a piston assembly separating the pressure tube into first and second working chambers. A frequency dependent damper assembly, coupled to a piston rod at a position below the piston assembly, includes a plunger sleeve that is longitudinally moveable to transmit an adaptive force to a first valve assembly mounted to the piston assembly. The frequency dependent damper assembly includes first and second accumulation chambers that are separated by a floating piston. A second valve assembly, carried on the floating piston, controls fluid flow between the second accumulation chamber and the second working chamber. A bleed channel in the floating piston allows fluid flow between the first and second accumulation chambers, which reduces the adaptive force the plunger sleeve applies to the first valve assembly during high frequency, low velocity rebound inputs.

A valve assembly, mounted to the piston assembly, controls fluid flow between the first and second working chambers. A frequency dependent damper assembly, coupled to the piston rod at a position below the piston assembly, includes a plunger sleeve that is longitudinally moveable to transmit an adaptive force to a valve assembly. A plunger travel limiter, positioned longitudinally between the frequency dependent damper assembly and the valve assembly, contacts the plunger sleeve and prevents the plunger sleeve from moving further towards the piston assembly to limit the magnitude of the adaptive force applied to the valve assembly.

  • Publication number: 20190260228
    Abstract: An apparatus and methods to reduce current transient during power mode transfer in uninterruptible power supply (UPS). The disclosure provides a zero-cross detection based phase width modulated (PWM) element (E3). The element (E3) is configured to delay activation of a PWM modulator, by delaying a PWM start command for a first delay time (Tdz), wherein the first delay time is the time between receiving a static switch command to the time when a positive sequence component of a phase load current crosses zero. The element (E3) is further configured to delay the activation of the PWM modulator for a second delay time (Tdi) after the end of the first delay time (Tdz), by delaying the PWM start command for the second delay time, wherein the second delay time is based on a power factor of load connected to the UPS.

  • Publication number: 20180299356
    Abstract: A sampler apparatus is disclosed. The sampler apparatus comprises an impactor assembly comprising a nozzle plate, an impaction plate, and a filter unit. The nozzle plate comprises a plurality of nozzles for channelling an air stream through the sampler apparatus. The impaction plate is adapted to collect particulate matter having size equal to or greater than a threshold size. The filter unit is adapted to collect particulate matter having size less than or equal to the threshold size. The sampler apparatus further comprises a control assembly coupled with the impactor assembly. The control assembly comprises one or more flow control devices to maintain a predetermined air-flow rate of the air stream within the sampler apparatus.

  • Patent number: 10082837
    Abstract: In one general aspect, a computing device includes a lid, and a base coupled to the lid by a hinge, the hinge including a bi-stable hinge part including a toggle pivot and a toggle link bar, and a barrel hinge part including a hollow shaft, at least one friction element surrounding a first portion of the hollow shaft, and a casing surrounding a second portion of the hollow shaft, the casing being connected to the toggle link bar. The computing device includes a first mounting tab connected to the toggle link bar and connected to the base, and a second mounting tab connected to the at least one friction element and connected to the lid. The barrel hinge part enables the at least one friction element to rotate about the hollow shaft causing the lid to rotate relative to the base.
