  • Publication number: 20190038224
    Abstract: Wearable devices having pressure activated biometric monitoring systems and related methods are disclosed. An example wearable device includes a housing including a biometric sensor to detect physiological information of a user. The wearable device includes a circuit to electrically couple the biometric sensor and a power source of the wearable device. A spring contact is positioned adjacent the biometric sensor and is to be oriented toward a user. The spring contact is movably coupled relative to the housing. The spring contact is to close the circuit to activate the biometric sensor when the wearable device is strapped to the user and the spring contact engages the user. The spring contact is to open the circuit to deactivate the biometric sensor when the wearable device is removed from the user to reduce energy drain of the power source by the biometric sensor.

  • Patent number: 9974235
    Abstract: A device for harvesting mushrooms from a mushroom bed involves a robotic arm configured to interchangeably deploy one of a plurality of different suction grippers, each of the suction grippers having a suction cup having a size and shape profile appropriate for gripping a cap of a mushroom, the cap having a size and shape profile within a predetermined range. A vacuum source in fluid communication with the suction gripper supplies negative air pressure to the suction gripper for retaining a cap of the mushroom to be harvested in the suction cup. A control circuit in electronic communication with the suction gripper and the vacuum source is configured to automatically adjust the negative air pressure in the suction gripper in response to harvesting requirements during a mushroom harvesting process.
