Internal combustion engine control for improved fuel efficiency
A variety of methods and arrangements for improving the fuel efficiency of internal combustion engines are described. Generally, selected combustion events are skipped during operation of the internal combustion engine so that other working cycles can operate at a better thermodynamic efficiency. In one aspect of the invention, an engine is controlled to operate in a variable displacement mode. In the variable displacement mode, fuel is not delivered to the working chambers (e.g. cylinders) during selected “skipped” working cycles. During active (“non-skipped”) working cycles, a maximum (e.g., unthrottled) amount of air and an optimized amount of fuel is delivered to the relevant working chambers so that the fired working chambers can operate at efficiencies closer to their optimal efficiency. A controller is used to dynamically determine the chamber firings required to provide the engine torque based on the engine's current operational state and conditions. The chamber firings may be sequenced in real time or in near real time in a manner that helps reduce undesirable vibrations of the engine. |

Efficient visualization of cortical vascular territories and functional MRI by cycled arterial spin labeling MRI
Regional arterial spin labeling (regASL) speeds up acquisition without sacrificing the signal-to-noise ratio (SNR) of the resulting perfusion images by using the same control image (i.e. acquired without labeling of blood in a vessel) for two or more vascular territory measurements. This regional ASL is accomplished by creating prepared spin magnetization (e.g. inverted or saturated) in a specific blood vessel, instead of preparing spin magnetization in all feeding blood vessels. As in conventional ASL, two data sets are typically acquired in a downstream position: one with (label image) and one without preparation (control image) in one particular vessel. When regASL is extended to repetitive time series of ASL images to identify perfusion changes for functional MRI (fMRI), the speed of the time series of ASL also is increased because only a single C data set can be used redundantly for all time points of ASL measurement, to reduce the amount of data acquired by nearly one half, with no change in the signal to noise ratio in the ASL images. To account for possible movement of the person causing misregistrations in the time series, the C data can be obtained two or more times throughout the time series while still at lower frequency than in prior techniques with alternating L and C data sets. |

Nonlinear precoding method for a digital broadcast channel
Several subscriber signals are transmitted simultaneously and at the same frequency by a central transmitter to several decentralized receivers which do not cooperate with each other, by digital message transmission in a broadcast channel. A common transmission signal, which enables an error-free individual reception, should be generated with knowledge of all subscriber signals and of the current transmission conditions, by signal preprocessing methods on the transmission side. Known nonlinear precoding methods totally suppress the interference signals, so that the channel diversity cannot be used. In the claimed precoding method, the occurring interference signals are, on the contrary, taken into account. On the basis of a modulo arithmetic calculation, the transmission channel is not totally equalized, but virtually divided, so that the transmission of the subscriber signals is continued periodically; the signals are selected according to the minimal transmission power and pre-equalized, in a linear manner, and the residual interferences, still remaining between the subscriber signals, may assume special values from a preset set of values. The set of values is selected, so that the interference signals of the other subscribers are also merely reflected in the otherwise already existing periodic continuation and can be suppressed or used as required by a modulo decision, on the reception side. |

Downstream synchronous multichannels for a communications management system
Downstream synchronous multichannel (DSSM) communications are provided among a plurality of carriers, each being a completely DOCSIS™ 2.0-compliant downstream. The synchronous multichannels support communications with both DSSM-capable communications nodes and non-DSSM-capable communications nodes (e.g., legacy cable modems). Non-DSSM packets are transmitted on a single channel. DSSM packets are split into multiple pieces, which are transmitted simultaneously on all available channels.

Method for transferring data in a wireless network
The invention is directed to a process for transferring data packets through a protocol stack employed by the device for transmitting packets on a packet connection to a wireless network, said wireless network operating at least two, distinct wireless access technologies such as GSM/GPRS and UMTS. The packet transfer process generally comprises each layer of a protocol stack for a currently active packet connection path providing confirmation to a next, higher layer in the stack of successful reception of a data packet from that layer, thereby confirming successful transfer of the data packet through the stack. The first layer of the stack stores a copy of a transferred packet until such time as its receives confirmation from the next, lower layer of successful transfer of the packet of the stack. In the absence of such confirmation and on the occurrence of a switch (hand-off) of the packet connection to a new connection path, particularly one of a different wireless access technology, the stored packet is transferred to the protocol stack to be employed by the wireless device for the new packet connection path. Consequently, the packet transfer process avoids packets being lost on the occurrence of a switch between different technology wireless access packet connection paths. |

Simplex personal and asset tracker
Disclosed are systems, apparatus and methods for tracking or locating an asset along with providing emergency and non-emergency messaging services. An asset tracker is disposed on an asset. The asset tracker has a motion sensor, a GPS receiver and a simplex satellite transmitter for communicating with a remote location (back office processing center). The asset tracker also has a short-range transceiver for communicating with a fob device carried by a user. If an authorized fob device is not in range of the asset tracker device and the asset tracker device moves, as determined by the motion sensor and/or GPS location data, GPS data are transmitted via a satellite to the back office. The office sends the information to a desired recipient (asset owner, law enforcement, etc.). The fob device communicates with the asset tracker device when it is in proximity thereof. The fob device is programmed to have depressible buttons that transmit emergency and non-emergency messages to the asset tracker device which communicates the GPS location and message via a satellite to the back office. The back office sends the information to a desired recipient. Messages processed at the processing center are sent as email messages to one or more designated email addresses, as a short message service (SMS) messages to one or more designated cell phones, or as messages to an asset recovery service or 911 emergency center. |

Linear vibration generator
A linear vibration generator is disclosed. The linear vibration generator may include: a stator having a coil, which induces a magnetic field when an electric current is applied; an oscillator having a magnet, which has one side facing the coil; a spring member, which is joined to the stator, and which elastically supports the oscillator such that the oscillator moves linearly; a damper, which prevents the oscillator from contacting the stator according to the linear motion of the oscillator; and a guide portion, which guides the linear motion of the oscillator. This linear vibration generator makes it possible to generate stable linear vibration, prevent generation of touch noise when the oscillator impacts the stator, and prevent right/left vibration due to an external impact. |
