  • Publication number: 20240168528
    Abstract: An information handling system bay accepts plural communication carriers having storage communication support, such as in compliance with OCP3.0. The communication carrier has a support structure to support processing components, such as a network interface controller coupled to a printed circuit board, and coupled within the bay by a latch having a member extending from one end to engage the bay housing and latching an opposite chamfered end with a pin coupled to a spring loaded button. A press on the button away from the latch releases the chamfered end from the pin so support structure member is free from the housing bay to remove the communication carrier.

  • Patent number: 8448924
    Abstract: A secondary-fuel inductor for an engine including a carburetor with a primary fuel inlet having an outlet end. The inductor includes a gasket and a fuel conduit. The gasket defines an opening through which the fuel conduit extends. The fuel conduit has a bend defining a first segment and a second segment. The first segment includes a gasket-spanning segment that extends through the fuel-conduit opening and an inlet end that can have a connector for connection to a fuel line for a secondary fuel. And the second segment includes an outlet end positioned within a venturi area of the carburetor, for example, immediately adjacent the outlet end of the primary fuel inlet.

  • Patent number: 7983769
    Abstract: A system that enables controlling motion over a network comprises an interface that receives motion control data that includes a time stamp from the network. Additionally, the system includes a motion control component that utilizes the received motion control data to update properties associated with the motion control component based at least in part on the time stamp. The system can also include a clock that is synchronized with disparate clocks associated with disparate motion control components located on the network.

  • Patent number: 7719219
    Abstract: An electronic line shaft comprising a motor drive comprising a velocity noise filter coupled to receive a feedback position signal and operable to filter the feedback position signal to generate a feedback velocity signal where the noise filter has at least one controllable filter parameter that affects filter operating characteristics and a processing unit operable to execute a wizard for configuring the motor drive, the wizard being operable to receive mechanical characteristic data associated with the motor drive that is provided as input by a wizard user via a user interface and to determine a noise parameter based on the mechanical characteristic data, wherein the at least one controllable filter parameter is adjusted as a function of the noise parameter.

  • Patent number: 6502461
    Abstract: A method and system for remote monitoring of liquid level 21 within a container 12, such as the level of fuel within a propane cylinder. A magnetic float 20 disposed within the container 12 floats on the liquid 21, and lowers with the liquid level as fuel is consumed. Magnetic sensors 22 outside the container 12 sense the float 20 as it passes in the proximity of one of the sensors 22. A controller 26 receives output signals from the sensors 22 and transmits level indicating signals to a gauge 28 or other indicator for remote indication of the corresponding liquid level. The indicator 28 can be located proximal the user's direct line of sight, to remind the user to periodically monitor the fuel level to prevent running out of fuel.

  • Patent number: 6371074
    Abstract: A system and method for minimizing the likelihood of backfiring as a spark ignition, internal combustion engine is turned off. A fuel cut-off device stops the flow of fuel into the engine in response to an engine shut-off control signal, such as when the on-off keyswitch is moved from the “on” position to the “off” position. The ignition spark is maintained to the engine for a predetermined length of time after fuel shut-off. The delay time is selected to allow the fuel cut-off device to operate to stop the flow of fuel into the engine. In this way, for as long as the engine is turning over, the engine is provided with an electric spark for controlled ignition, thereby minimizing or eliminating backfiring.
