    摘要: A loop-powered field device (32) includes a plurality of terminals (52, 54) coupleable to a process communication loop (36) and a loop control module (56) coupled to one of the plurality of terminals (52, 54) and configured to control an amount of current flowing through the loop control module (56) based on a control signal. A field device main processor (58) is operably coupled to the loop control module (56) to receive its operating current (I_Main) from the loop control module (68) and is configured to provide the control signal based on a process variable output. A low power wireless communication module (56) is operably coupled to the loop control module (56) to receive its operating current (I_BLE) from the loop control module (56). The low power wireless communication module (68) is communicatively coupled to the field device main processor (58). The low power wireless communication module (68) has an active mode and a sleep mode. The low power wireless communication module (68) is configured to obtain a measurement of operating current (I_BLE) available while the low power wireless communication module (68) is in the sleep mode and modify an active cycle of the low power wireless communication module (68) based on the measurement of operating current (I_BLE).

    摘要: Provided herein is an integrated circuit including, in some embodiments, a host processor, a digitally implemented neural network co-processor, and a communications interface between the host processor and the co-processor configured to transmit information therebetween. The special-purpose host processor can be operable as a stand-alone processor. The neural network co-processor may include a digitally implemented neural network. The co-processor is configured to enhance special-purpose processing of the host processor through an artificial neural network. In such embodiments, the host processor is wake keyword identifier processor configured to transmit one or more detected patterns to the co-processor over a communications interface. The co-processor is configured to transmit the recognized patterns to the host processor which can then identify and verify wake keywords spoken by a known user.

    摘要: A mobile device (400) is provided and includes a sensor (407) and a control module (402). The sensor is configured to detect movement of the mobile device. The control module is configured to: based on an output of the sensor, determine whether the mobile device is moving; when the mobile device is moving, transmit via a transceiver (408) at least one signal to a vehicle (200) indicating movement of the mobile device and an indication of presence of the mobile device; based on the at least one signal, receive an instruction signal or an information signal from the vehicle via the transceiver; based on the instruction signal or an information signal, at least one of reduce a polling rate of the mobile device, cease to indicate presence of the mobile device or transition to a sleep mode; and transition from the sleep mode to an awake mode in response to movement of the mobile device.

    摘要: 本发明提出了一种事件驱动型常开唤醒芯片。每级由上一级输出的事件驱动工作,也即每一级在其输入信号满足软件编程的阈值条件时才能输出并驱动下一级,反之则处于待机状态。此外,芯片具有对信号的多种基本处理模式,如幅度,时间,斜率等,并且,可通过软件编程的方式设置各个基本模式对信号事件判断的阈值条件,以及对各个基本模式进行复杂的组合,实现对信号多样的高级检测模式,使芯片在保持超低功耗的同时具有通用性,也即软件定义芯片。本发明各个模块都是无时钟全异步的工作模式,它们无静态电流偏置,功耗极低。本发明的编程功能可以拓宽唤醒芯片的通用性,让其随着需求的实时变化而呈现相应的功能。
