  • Publication number: 20250331735
    Abstract: Embodiments herein relate to detection devices. In an embodiment, a method of detecting THC compounds, is included, the method includes receiving an exhaled breath sample; electrochemical processing of the exhaled breath sample using a fluorescent molecule to form a fluorescent-labeled THC adduct; purifying the fluorescent-labeled THC adduct; and determining an amount of THC in the exhaled breath sample based on a measured fluorescence of the purified fluorescent-labeled THC adduct; wherein the fluorescent-labeled THC adduct is formed without a highly-reactive handle. Other embodiments are also included herein.

  • Patent number: 11696807
    Abstract: Disclosed herein are methods to detect a free-falling or other non-surgical motions of the user interface device (UID) of a surgical robotic system so that the surgical robotic system may pause the robotic arm controlled by the UID to prevent the robotic arm from mimicking the unintentional movement of the UID. Contact sensors embedded in the UID may be used to detect conditions indicating that a user does not possess full control of the UID. After determining that the user does not have full control of the UID, the UID may detect if the UID is experiencing non-surgical motions using motion sensors such as inertial sensors. By conditioning analysis of the data from the motion sensors by the initial determination that the UID is not being held based on the contact sensors, the method increases the robustness of the detection of non-surgical motions and reduces the probability of false positives.

  • Patent number: 11504200
    Abstract: Wearable user interface devices are described. A wearable user interface device can include a wearable base connected to a trackable device component by a linkage. The linkage can connect to a pivoted support that the trackable device is mounted on, and which maintains poses when the user interface device is not manipulated by a user's hand. The pivoted support has several orthogonal axes intersecting at a center of rotation located inside a device body of the trackable device. Other embodiments are also described and claimed.
