  • Publication number: 20220290646
    Abstract: Methods and systems are provided for restarting an engine following an engine idle-stop. In one example, a method may include, prior to an engine restart following an idle-stop, adjusting a spark ignition timing based on an estimation of a fuel-air equivalence ratio (phi) and an estimation of a cylinder turbulence. Optimal spark ignition timing based on estimated phi and cylinder turbulence during engine restart may result in stabilized combustion and a torque output sufficient to at least partially relieve demand on the starting device.

  • Publication number: 20220219670
    Abstract: Methods and systems are provided for engaging and disengaging an electromagnetic clutch of a two-speed accessory drive of an engine of a vehicle. In one example, a method comprises, responsive to an electrical demand being higher than a threshold electrical demand, operating an electric machine of the vehicle in a motor mode to reduce a speed of a grounding gear of a planetary gear set of a two-speed accessory drive (TSAD) of the vehicle; and engaging an electromagnetic clutch responsive to the speed of the grounding gear reaching a clutch engagement threshold speed.

  • Patent number: 10161349
    Abstract: Methods and systems are provided for increasing a lift pump voltage to a high threshold voltage responsive to a DI pump efficiency being below a threshold efficiency, and increasing a lift pump voltage to a first threshold voltage less than the high threshold voltage responsive to a main jet pump fuel reservoir level being less than a first threshold reservoir level. The approach increases fuel jet pump performance and thereby reducing engine stalls induced by fuel vaporization, while maintaining DI pump efficiency and fuel economy.

  • Patent number: 9683511
    Abstract: An engine system and method for adjusting pressure of fuel supplied to an engine responsive to compressibility of fuel supplied to the engine is disclosed. In one example, the engine is operated with a fuel pump in an off state to determine compressibility of fuel supplied to the engine. Fuel pressure supplied to the engine is adjusted responsive to the fuel compressibility.

  • Patent number: 8427315
    Abstract: RFID reader systems, software and methods precompute one or more reader commands, before a tag actually responds to an earlier transmitted command. This way a system can result at a high data rate, while meeting specification requirements of responding within a preset time.

  • Patent number: 8120494
    Abstract: RFID readers, reader systems, and methods are provided that utilize smart antenna switching. A first signal is transmitted from a first antenna estimating presence of tags within the antennas field of view. If fewer than a predefined number of tags are estimated, the system switches to a second antenna. Otherwise, the tags found in the field of view of the first antenna are inventoried before switching to the second antenna.

  • Patent number: 7830262
    Abstract: RFID reader systems, readers, components, software and methods are provided for inventorying RFID tags. In some embodiments, a population of RFID tags begins being inventoried using a first set of communication parameters, and then continues using a second set of communication parameters. This way, some RFID tags can be inventoried faster, without missing tags that require a longer time to read.

  • Publication number: 20080266098
    Abstract: Radio Frequency IDentification (RFID) reader system, software, and methods are provided, such that an operational processing block for the RFID reader to communicate with an RFID tag uses a RF spectrum portion subdivided into a set of channels. The communication takes place in the presence of a foreign device that uses a subset of first channels of the RF spectrum and does not use a subset of second channels of the spectrum. The methods cause a radiating power directed towards the tag to be reduced and a radiating dwell time to be changed. This is to assure that co-existing systems can operate without compromising their functionality and operational quality. In some embodiments, the radiating power is reduced to zero.
