摘要： A method for controlling power consumed by a plurality of subsystems on a multi-car train having a plurality of power supplies connected in parallel for supplying power to the subsystems. The train has a train wide communication network which includes a vehicle bus in each car of the train communicating with the power supplies and subsystems on the car, a train bus extending through the entire train, and communication nodes in each car interconnecting the train bus with each one of the vehicle buses. One of the communication nodes in one of the cars constitutes a master node and the other communication nodes in the other cars constitutes slave nodes, each slave node communicating status information about power supplies and subsystems on its vehicle bus to the master node and communicating control information to the power supplies and subsystems on its vehicle bus. The method includes using the communications network to periodically determine the number of functional power supplies connected in parallel, determining from the number of functional power supplies available for supplying power at any given time a variable corresponding to the total power available for power consuming subsystems on the train and selectively reducing subsystems on the train by way of the communications network in accordance with the variable determined by the determining step.

摘要： Embodiments of the disclosure describe data transmission via a touchscreen display of a mobile computing device. The mobile computing device includes a peripheral component, integrated into a touchscreen display surface housing, and a plurality of photonic pulse transmitters and receivers disposed on edges of the touchscreen display surface. One or more receivers receive pulses from the photonic pulse transmitters for detecting user touch inputs on the touchscreen display surface. A photonic pulse modulator modulates a pulse to be transmitted from one of the photonic pulse transmitters based, at least in part, on peripheral component data. A photonic pulse demodulator demodulates the modulated pulse received by the pulse detector(s) to retrieve the peripheral component data. By utilizing these pulse transmitters/receivers, used for user touch input detection, to also exchange data via modulated light, the bezel area around the touchscreen display surface may be reduced.

摘要： Briefly, in accordance with one or more embodiments, a phased array antenna may utilize Multilateration in order to implement beam steering with a phased antenna array. During a training phase, Multilateration equations may be utilized to determine a coordinate location of an antenna of a target device. The time difference of arrival of the training signal may be determined at selected antenna elements of the antenna array. The location of the antenna of the target device may then be calculated from which the propagation time may be determined. The propagation time may then be converted to relative phase shift values for each antenna element in the array with respect to a reference antenna element. A beam may then be directed toward the antenna of the target device by setting the elements of the antenna array with the calculated phase shifts.

摘要： A method is provided for performing a clear channel assessment in a local device. The local device receives signal energy in a wireless channel and splits the received signal energy into a real portion and an imaginary portion. It determines a real portion of a squared signal energy by subtracting a squared imaginary portion of the signal energy from a squared real portion of the signal energy, and determines an imaginary portion of the squared signal energy by calculating twice the product of the real and imaginary portions of the signal energy. It can perform a signal detection function on the real and imaginary portions of the squared signal energy to produce a clear channel assessment signal that indicates whether a set signal type is present in the wireless channel. This clear channel assessment signal can be used to determine whether the local device should remain in a low-power mode.

摘要： A multiple step process is performed at a local wireless network to limit interference between the local wireless network and a remote wireless network. Initially, a set of code words is chosen for the local wireless network to encode data with that have good cross correlation properties. If these initial code words are not adequate to prevent interference, then the local wireless network will adjust its transmission parameters by either shifting the transmission phase of its signals or by changing the code words it uses. If altering the transmission parameters does not alleviate the interference problem, then the local wireless network attempts to locate the interfering remote network and merge with it. If the merger is not possible or is unsuccessful, then the interference limiting process fails.
摘要翻译：在本地无线网络上执行多步骤过程以限制本地无线网络与远程无线网络之间的干扰。最初，为本地无线网络选择一组代码字以对具有良好互相关性质的数据进行编码。如果这些初始码字不足以防止干扰，则本地无线网络将通过移动其信号的传输阶段或通过改变其使用的码字来调整其传输参数。如果改变传输参数不能缓解干扰问题，则本地无线网络会尝试定位干扰远程网络并与之并网。如果合并不可能或不成功，则干扰限制过程失败。
