Abstract: A method of authenticating a mobile device over Bluetooth advertisements according to one embodiment includes broadcasting, by an access control device, a first Bluetooth advertisement including a challenge message generated by the access control device, receiving, by the mobile device, the first Bluetooth advertisement including the challenge message, broadcasting, by the mobile device, a second Bluetooth advertisement including a challenge response message generated by the mobile device based on the challenge message, receiving, by the access control device, the second Bluetooth advertisement including the challenge response message, and determining, by the access control device, whether the mobile device is authorized to perform an action with respect to the access control device by verifying the challenge response message.

Abstract: A method including placing a first adhesive on a first surface of a strike plate, wherein the strike plate includes a pocket extending into a second surface of the strike plate opposite the first surface of the strike plate. The method further includes placing a second adhesive on a first surface of a lock module, wherein the lock module includes a bolt operable to extend beyond a second surface of the lock module. The method also includes aligning the pocket with the bolt such that the bolt is operable to extend into the pocket, and with the pocket and the bolt aligned with one another, releasably joining the strike plate and the lock module with a releasable coupler, thereby forming an aligned locking assembly.

Abstract: An exemplary system includes a wireless power transmitter in power communication with a power supply, and a wirelessly-powered electronic device powered by the wireless power transmitter. The wirelessly-powered electronic device includes a wireless power receiver and an electronic device in power communication with the wireless power receiver, and may further include an energy storage device. During operation, the transmitter transmits electromagnetic radiation to the receiver, which in turn converts the electromagnetic radiation to electricity that is utilized by the electronic device. In certain embodiments, the transmitter is provided as an infrared laser.

Abstract: A microtiter plate transport device is configured to grip a microtiter plate in a first location. The microtiter plate transport device is configured to make a vertical approach to the microtiter plate and grip the microtiter plate in either a portrait orientation or a landscape orientation along either the opposing longer sides or the opposing shorter sides of the microtiter plate. The device comprises a Cartesian coordinate robot including a first gripping member and a second gripping member opposed to the first gripping member. The first gripping member and the second gripping member are supported by an arm configured to move along a vertical axis which extends between the first gripping member and the second gripping member. The first gripping member and the second gripping member are configured to rotate about the vertical axis.
