    • A recording device, such as a video camera, emits audio watermarks (e.g., audible tones, inaudible tones) and records audio watermarks emitted by other recording devices. The audio watermarks provide information (e.g., data) such as an identifier of the camera and the identity of the operate. Audio watermarks may further include time information such as a timestamp indicating the time that the audio watermark was emitted by the camera. Audio watermarks may be emitted and recorded at intervals while recording an incident. A processing system, such as a digital video and audio processing system, may receive video information and recorded watermarks from multiple recording devices. The processing system may use the audio watermarks recorded by each recording device to determine which recording devices were in the vicinity of an incident. The processing system may also use the audio watermarks to align (e.g., synchronize) the video recorded by the various recording devices. Alignment of recorded video may permit synchronized playback of the recorded video from the various recording devices. Alignment may further identify at what point during an incident a recording device began and terminated recording.
    • 诸如摄像机之类的记录设备发出音频水印(例如,可听音,听不见的音调)并记录由其他记录设备发出的音频水印。 音频水印提供信息(例如数据),例如相机的标识符和操作的标识。 音频水印还可以包括时间信息,例如指示音频水印由相机发射的时间的时间戳。 录制事件时,音频水印可能会间隔发射并记录。 诸如数字视频和音频处理系统的处理系统可以从多个记录设备接收视频信息和记录的水印。 处理系统可以使用由每个记录设备记录的音频水印来确定哪些记录设备处于事件附近。 处理系统还可以使用音频水印来对齐(例如,同步)由各种记录设备记录的视频。 录制的视频对齐可以允许从各种录制设备同步播放录制的视频。 对齐可以进一步确定记录设备在事件发生时的哪个点开始并终止记录。

    • Systems and methods for immobilizing a target such as a human or animal with a stimulus signal coupled to the target via electrodes provide the stimulus signal in accordance with a strike stage, a hold stage, and a rest stage. Systems include a launch device (102) and separate projectile (132), where the projectile includes a battery (134), a waveform generator (136), and electrodes. The strike stage and hold stage may include pulses at a pulse repetition rate, for example, from 10 to 20 pulses per second, each pulse delivering a predetermined amount of charge, for example, about 100 microcoulombs at less than about 500 volts peak. The hold stage may continue immobilization at a lesser expenditure of energy compared to the strike stage. Because the strike stage and hold stage may immobilize by interfering with skeletal muscle control by the target's nervous system, a rest stage may allow the target to take a breath.
    • 用于通过电极耦合到目标的刺激信号来固定诸如人或动物的靶的系统和方法根据击发阶段,保持阶段和休止阶段提供刺激信号。 系统包括发射装置(102)和单独的射弹(132),其中射弹包括电池(134),波形发生器(136)和电极。 触发阶段和保持阶段可以包括脉冲重复率的脉冲,例如每秒10至20个脉冲,每个脉冲在小于约500伏特峰值处递送预定量的电荷,例如约100微库仑。 与罢工阶段相比,持有阶段可能以较少的能源消耗继续固定。 因为通过干扰目标神经系统的骨骼肌肉控制,罢工阶段和暂停阶段可能会停止,休息阶段可能允许目标呼吸。

    • A signal generator provides an output signal having a series of pulses and a pulse repetition rate. The signal generator includes an energy storage circuit (224) and a switch control circuit (223). The energy storage circuit includes a switch operated by the switch control circuit. After delivery of a pulse of the output signal, the switch control circuit operates the switch in a first mode to provide the pulse repetition rate of the output signal. The switch control circuit also operates the switch in each of the first mode and a second mode at a switching rate, wherein relatively more energy from a battery (207) is stored as a consequence of the second mode than is stored as a consequence of the first mode. Energy from the battery is stored for delivery in a pulse of the output signal. The switching rate is compensated in accordance with a temperature of the battery and a voltage of the battery. Compensation maintains the battery voltage above a minimum value. Operation according to the value avoids current draw from the battery at a rate that may lead to an under-voltage condition of the battery. In one implementation, the power supply provides a high voltage for charging a capacitor for each cycle of an electric discharge weapon. Another value conveyed by the serial data provides a maximum pulse delivery rate for such a weapon.
    • 信号发生器提供具有一系列脉冲和脉冲重复率的输出信号。 信号发生器包括能量存储电路(224)和开关控制电路(223)。 能量存储电路包括由开关控制电路操作的开关。 在输出信号的脉冲之后,开关控制电路以第一模式操作开关以提供输出信号的脉冲重复率。 开关控制电路还以切换速率在第一模式和第二模式中的每个模式下操作开关,其中作为第二模式的结果来自电池(207)的相对较多的能量被存储为由于 第一模式 存储来自电池的能量以输出信号的脉冲。 根据电池的温度和电池的电压来补偿开关率。 补偿将电池电压维持在最小值以上。 根据该值的操作可以避免以可能导致电池欠压状态的速率从电池中抽出电流。 在一个实施方案中,电源为放电武器的每个周期提供用于对电容器充电的高电压。 由串行数据传达的另一个值为这种武器提供了最大的脉冲传送速率。
