  • Publication number: 20240138924
    Abstract: A first ultrasonic beacon transmission includes a first pilot signal and a first encoded information signal. An apparatus may detect the first pilot signal and decode, based on the first pilot signal, the first encoded information signal to identify a medical system associated with the first ultrasonic beacon transmission. Based on the first encoded information signal, the apparatus may enter into a first pairing state in which the apparatus is communicatively paired with the medical system. While the apparatus is operating in the first pairing state and within a threshold time of entering the first pairing state, the apparatus may detect a second pilot signal included in a second ultrasonic beacon transmission, which also includes a second encoded information signal. Based on the detection of the second pilot signal within the threshold time, the apparatus may continue operating in the first pairing state without decoding the second encoded information signal.

  • Patent number: 9488456
    Abstract: Detonation control modules and detonation control circuits are provided herein. A trigger input signal can cause a detonation control module to trigger a detonator. A detonation control module can include a timing circuit, a light-producing diode such as a laser diode, an optically triggered diode, and a high-voltage capacitor. The trigger input signal can activate the timing circuit. The timing circuit can control activation of the light-producing diode. Activation of the light-producing diode illuminates and activates the optically triggered diode. The optically triggered diode can be coupled between the high-voltage capacitor and the detonator. Activation of the optically triggered diode causes a power pulse to be released from the high-voltage capacitor that triggers the detonator.
