Abstract: Systems, devices, and methods described herein indirectly monitor a state of fluid flow by monitoring a state of connection of a medication delivery device. The system includes an enclosure, a contact sensor, and a controller. The enclosure can attach around at least a portion of an outer surface of the medication delivery device to enclose at least a portion of the outer surface therein. The contact sensor and controller are enclosed within the enclosure. The contact sensor can monitor a state of electrical connection. The controller is in communication with the contact sensor and can relay the state of electrical connection. The state of connection of the contact sensor corresponds to the state of connection of the medication delivery device.

Abstract: The quantum relay and quantum signal source exploit quantum properties of photon streams. A pair of spatially separated and polarization-entangled photon streams is used. The pair collectively exist in a quantum superposition state by virtue of their mutual entanglement. In the relay, an encoder establishes a modulation control signal corresponding to the information to be conveyed. An optical quantum circuit is placed in the path of one of the pair of streams, so that the first stream passes through it. The optical quantum circuit alters the quantum polarization state of the photon passing through it based on the control signal. In this way information is encoded into quantum probability distributions of the superposition state through quantum parallelism and quantum interference, whereby information is conveyed in the photon streams.

Abstract: An offloading schedule for offloading image frames that are to be generated by an AR device in a subsequent time period is determined, the offloading schedule identifying certain image frames generated in the subsequent time period that are to be offloaded and certain image frames generated in the subsequent time period that are not to be offloaded, the offloading schedule being selected from a plurality of offloading schedules based on a tracking stride of the offloading schedule. The AR device sends to a computing device at least some of the image frames generated in the subsequent time period in accordance with the offloading schedule.

Abstract: A toner container for use with a developer unit of an image forming device includes a body having a reservoir for holding toner and an engagement arm that is movable relative to the body between a disengaged position and an engaged position. The engagement arm includes a first engagement surface for contacting a cam surface in the image forming device and receiving an actuation force from the cam surface to move the engagement arm from the disengaged position to the engaged position when the toner container is inserted into the image forming device. The engagement arm includes a second engagement surface for contacting and applying a hold-down force on a portion of the developer unit when the engagement member moves from the disengaged position to the engaged position when the toner container is inserted into the image forming device with the developer unit installed in the image forming device.

Abstract: A method for treating a heart valve involves introducing a delivery system holding a papillary muscle manipulation device into a ventricle of a heart. The papillary muscle manipulation device includes a spring coil, a first arm that emanates from a first end of the spring coil, and a second arm that emanates from a second end of the spring coil. The method further involves deploying the papillary muscle manipulation device from the delivery system between a first papillary muscle and a second papillary muscle within the ventricle, wrapping the first arm around first papillary muscle anatomy associated with the first papillary muscle, wrapping the second arm around second papillary muscle anatomy associated with the second papillary muscle, and using spring force of the spring coil to draw the first arm and the second arm together to thereby draw the papillary muscles together.

Abstract: A sash lock housing enable screwless installation with respect to an opening in a sash window meeting rail, and includes a front, rear, and top walls. The top wall has a flat bottom surface. The rear wall includes first and second cantilevered ends, and a lip with a flat top surface being separated a small distance from the top wall's flat bottom surface that is configured to cause respective engagement with a top surface and a bottom surface of a top wall of the meeting rail, when the sash lock is inserted into the meeting rail opening. Also, the first and second cantilevered portions respectively engage first and second inside surfaces of a side wall of the meeting rail, to maintain the engagement between the top wall of the meeting rail and each of: the lip and the flat bottom surface of the top wall of the housing.

Abstract: An environmental monitoring network has transportable, self-contained, environment sensing capsules, each capsule is water-proof, with first and second sections, the second section being hollow. Apertures in the capsule's housing enable fluid and gas entry wherein first sensor(s) disposed internal to the housing measure within the hollow, and second sensor(s) disposed external to the housing measure external to the housing. A controller and power system are connected to the first and second sensors and transmits measured data. An access entry way is on a side of the housing, enabling access to first sensors, controller system, power system, and the communication system. A central data server is configured to receive and analyze the measurement data sent from the capsules. There is a priority list of appropriate personnel for contact by the central data server in an event there is an emergency condition at a capsule location.
