Abstract:
A power system for a vehicle may comprise an electric machine attached to an engine of the vehicle. The electric machine may comprise only one stator core; a stator main winding wound on the one stator core; a stator exciter winding wound on the one stator core. The stator main winding and the stator exciter winding may be magnetically independent from one another even though magnetic-field-isolation material is not interposed between the stator main winding and the stator exciter winding.
Abstract:
Disclosed are a retransmission method, a base station, and a user device in a multicast system. In order to reduce uplink signaling resource, a new MNI (Multiple NACK Indicator) message is added to an uplink common feedback channel in an existing E-MBMS system. The MNI message enables decision of an XOR retransmission group which satisfies the XOR retransmission condition. As compared to a conventional XOR retransmission, the number of uplink signalings does not depend on the number of receivers. That is, when a plenty of receptions are present, it is possible to significantly reduce uplink signalings.
Abstract:
In embodiments of a dynamic impedance circuit, a power circuit of a device charges and/or powers the device when the device is connected to a power source. A dynamic impedance circuit is coupled to the power circuit of the device and to the power source. The dynamic impedance circuit can operate with low impedance, and alternatively, can operate with high impedance responsive to an increased voltage across the dynamic impedance circuit, such as when a chassis of the device is coupled to ground.
Abstract:
Methods for processing substrates in twin chamber processing systems having first and second process chambers and shared processing resources are provided herein. In some embodiments, a method may include flowing a process gas from a shared gas panel to a processing volume of the first process chamber and to a processing volume of the second process chamber; forming a first plasma in the first processing volume to process the first substrate and a second plasma to process the second substrate; monitoring the first processing volume and the second processing volume to determine if a process endpoint is reached in either volume; and either terminating the first and second plasma simultaneously when a first endpoint is reached; or terminating the first plasma when a first endpoint is reached in the first processing volume while continuing to provide the second plasma in the second processing volume until a second endpoint is reached.
Abstract:
A high viscosity aqueous inkjet ink that is useful in ink jet printers. The ink comprises heat activated colorant solids that are not heat activated during the printing process, and are printed onto a substrate in the form of an image that can be transferred onto a subsequent or final substrate by applying heat and intimate contact between the two substrates. The ink can also be heat activated onto the substrate without further transfer by applying heat at the temperature that is suitable for the activation of the colorant.
Abstract:
A non-isolated inverter including a DC input-side, a capacitor connected in parallel with the DC input-side, an AC output-side connected in parallel with a load, and first and second bridge-arm units is provided. The first and second bridge-arm units are connected in parallel with the capacitor. The first bridge-arm unit includes a series forward-connection of upper and lower switch-elements, where a common-node of upper and lower switch-elements and a supplying terminal of the second bridge-arm unit are respectively connected to two terminals of the AC output-side. The upper and lower switch-elements are respectively turned on in positive and negative half cycles of an output current of the non-isolated inverter, and the generation of common-mode currents in the non-isolated inverter is suppressed under a clamping action between the upper and lower switch-elements due to there are no high-frequency voltages on the parasitic-capacitors from the non-isolated inverter to the ground.

There is provided a method and device for feeding back a pre-coding matrix index of a dual-polarized antenna which has a first antenna array and a second antenna array and is arranged at a base station to which the index of a first pre-coding matrix for the first antenna array, the index of a second pre-coding matrix for the second antenna array and the phase offset between the first pre-coding matrix and the second pre-coding matrix are fed back from a terminal, comprising: computing a distance between the first pre-coding matrix and the second pre-coding matrix; judging whether the distance is larger than a predetermined threshold or not; and assigning less bits to indicate the phase offset if the distance is larger than the predetermined threshold. The method and device according to the present disclosure can effectively advance the feedback accuracy of a system thus improving the bit error rate and throughput of the system.

The present disclosure provides an orthogonal codes based code division multiplexing method of performing the code division multiplexing of demodulation reference signals in multiple layers of resource blocks by using orthogonal matrices, the method comprising: changing the order of chips in particular rows of a first orthogonal matrix to obtain a second orthogonal matrix with the changed order of chips; and multiplying the chips in respective rows of the second orthogonal matrix by the demodulation reference signals in corresponding layers of resource blocks correspondingly in the time direction to obtain code division multiplexing signals. The technical scheme of the present disclosure can improve the power jitter situation of downlink signals on the time, thereby the usage efficiency of the power amplifier at the base station side can be improved.

The present disclosure provides a method of generating codebook in a wireless communication system with multiple antenna arrays, as well as a wireless communication system, base station and terminal using the codebook for communication. The method comprises steps of: providing a basic codebook which cotains multiple pre-coding matrices; and assigning phase offsets to certain pre-coding matrices in the basic codebook to form a codebook with phase offset. The feedback overhead from a client to a base station side is reduced and a good precision of feedback for multi-antenna array is kept by applying the method of generating codebook and using the generated codebook in the wireless communication system, base station and terminal.
