  • Publication number: 20240092267
    Abstract: A vehicular interior rearview mirror assembly includes a mirror head pivotally adjustable about a mirror support. The mirror head includes a video display device disposed rearward of a prismatic mirror reflective element having a transflective mirror reflector. A touch sensor is disposed at the prismatic mirror reflective element and is associated with circuitry at a flexible printed circuit of the video display device. The video display device is operable to display video images captured by a rearward viewing camera of the vehicle. Light emitted by the video display device passes through the transflective mirror reflector for viewing of displayed video images by the driver of the vehicle viewing the prismatic mirror reflective element. The reflective region of the transflective mirror reflector of the prismatic mirror reflective element reflects at least 40 percent of visible light incident at the front side of the prismatic mirror reflective element.

  • Publication number: 20230376069
    Abstract: Embodiment herein provides an Infrastructure article (101) and method thereof for synchronizing blinks of infrastructure articles in a mesh network. The method includes detecting an expiry of a sync timer counted by a real time clock (RTC) and determining whether a charge level of a battery (105) of the infrastructure article (101) meets a battery charge threshold. When the charge level of the battery (105) of the infrastructure article (101) meets the battery charge threshold, the method includes establishing a connection with other infrastructure article and/or an infrastructure article server (200) in the mesh network, and sending a time to synchronize blink of the at least one light source (106) to all other infrastructure articles in the mesh network. When the charge level of the battery (105) of the infrastructure article (101) does not meet the battery charge threshold, the method includes resetting the sync timer, and initiating a count of the sync timer.

  • Patent number: 11246644
    Abstract: A surface ablation system includes an electrosurgical generator, and elongated shaft, a plug, and a circuit assembly. The elongated shaft includes a proximal end portion and a distal end portion. The plug is supported on the distal end portion of the elongated shaft. The circuit assembly is supported on the plug and in electrical communication with the electrosurgical generator. The circuit assembly includes spaced-apart traces positioned in arrays about the plug. Each of the traces is configured to emit electrosurgical energy along the arrays to treat tissue positioned adjacent to the traces.

  • Patent number: 9655670
    Abstract: The electrosurgical systems and methods of the present disclosure include a tissue resistance measurement system that compensates for capacitive parasitics in a cable connecting an electrosurgical generator to and electrosurgical cable to estimate the real resistance of a tissue load. The electrosurgical generator includes an output stage coupled to an electrical energy source and generates electrosurgical energy. The electrosurgical generator includes a plurality of sensors sensing a voltage and current of the electrosurgical energy and a controller controlling the output stage. The controller includes a calculator that calculates a real part of an impedance based on the sensed voltage and current, an estimator that estimates a resistance of the tissue using a solution to a quadratic equation that is a function of the real part of the impedance, and a control signal generator configured to generate a control signal for the output stage based on the resistance of the tissue.
