Abstract: A system for heating a structure uses a cavitation engine connected to a water supply, and to a discharge pipe, a condensate storage tank connected to the discharge pipe, the storage tank collecting condensate from the discharge pipe, and a pump connected to the condensate storage tank via a transfer pipe and being configured to pump the condensate out of the storage tank, and ether directly back into the cavitation engine for reuse or into a mixing tank for mixing with water from the water supply, and then back to the cavitation engine. The system creates a closed loop so that no water is wasted, and the energy generation is as efficient as possible.

Abstract: A system for an automatic toilet cleaning solution dispenser. The toilet bowl cleaning apparatus sits in the tank of a toilet and attaches to the overflow pipe and the fill valve. A cleaning solution fluid is placed in a receptacle which attaches to the toilet bowl cleaning apparatus. When the toilet is flushed, water flows through the toilet bowl cleaning apparatus, and the Venturi effect causes the cleaning solution fluid to be pulled into the stream of water that is entering the toilet bowl via the overflow pipe.

Abstract: Systems and methods for seed germination and planting include: a germinator unit providing an environment for seeds to germinate in water, and means to deliver the germinated seeds in batch form, suspended in an aqueous hydrogel; and a planting unit to accept batches of suspended seeds and dispense the seeds, preferably in singulated manner, to selected locations in a planting environment. The planting unit may be man-portable, mounted on a trailer or autonomous vehicle, or substantially stationary for use in a greenhouse. The planting environment may be a field or it may be a planting tray, pot, or other container for use in a greenhouse.

Abstract: An electronic device displays an image during a communication between two people. The image represents one of the people to the communication. The electronic device determines a location where to place the image and displays the image such that the image appears to exist at the location.

Abstract: Disclosed are implementations of a lens cap assembly, each configured to shroud the lens of either a flashlight, an optical sight, or a night vision device. Each lens cap assembly comprises a sleeve, a removable lens or an anti-reflection element positioned within the sleeve, and a cap. The cap is attached to the sleeve by an elastic cord.

Abstract: The innovation relates to a pool covering system that is usable as a flooring surface. The pool covering system includes brackets and support beams spanning the pool opening. The beams provide structural support to cross members and flooring placed on top of the beams. The pool covering system does not require significant drainage of the pool and does not damage the pool structure during installation and use.

Abstract: A head-measuring device is disclosed and includes a support frame. The head-measuring device also includes a plurality of movable arms comprising a first set of movable arms and a second set of movable arms. The first set includes a first outermost arm, the second set includes a second outermost arm opposite the first outermost arm, and each movable arm is movable between a first position and a second position. The head-measuring device also includes a stationary arm coupled to the support frame such that the stationary arm is approximately equidistant between the outermost arms as the outermost arms are moved between the first and second positions. The plurality of movable arms are parallel to each other and to the stationary arm. The first and second sets of movable arms are mechanically linked such that the first set moves synchronously with the second set between the first and second positions.

Abstract: A reconfigurable three-dimensional lattice in and on which detergent solutions and other liquid films may be deposited and supported, wherein the lattice may be configured and reconfigured for use, cleaning, and storage.

Abstract: Disclosed is a shroud configured to convert an open emitter reflex sight into an enclosed emitter reflex sight. More specifically, the shroud includes a transparent window and is configured to be attached to the main body of the housing and thereby form an enclosure for the emitter of the reflex sight. In some implementations, the shroud is used in conjunction with a drainage plug assembly configured to seal drain openings in the main body of the open emitter reflex sight.

Abstract: A method of assessing Fallopian tubal patency includes introducing a distension medium into a patient's uterus, introducing a contrasting medium into the uterus, and observing the contrasting medium, for example, via a hysteroscope, to determine whether the contrasting medium flows into one or both Fallopian tubes. A device for assessing Fallopian tubal patency includes a chamber for receiving contrast media, a flow path through the chamber for delivering distension media to a patient's uterus, and a flow controller for regulating the flow of distension media to the patient's uterus. The flow path is configured to permit flow of contrast media from the chamber into the flow path.

Abstract: A modular, weight-shift controlled watercraft device is disclosed which includes a wireless handheld throttle controller comprising a body configured to avoid water intrusion, a throttle control interface configured to receive an input controlling a speed of the watercraft, a memory storing an operator profile setting, a wireless transmitter configured to communicate wirelessly with a microcontroller of the watercraft, a processor configured to communicate control information to the microcontroller of the watercraft via the wireless transmitter.

Abstract: An aerosol former for heat-not-burn and biodegradable e-cigarette includes a sectional member wrapped by a paper material. At least one section is a botanical section connected to more than one e-liquid section when used for heat-not-burn cigarettes, and without the botanical section when used for e-cigarettes. The e-liquid sections include a heated segment and a vapor permeable liquid-flow-inhibiting thermal barrier. Each of the heated segments may include a sandwich structure. The structure may include a porous sponge layer made from a cellulose fiber based non-woven material which is installed inside a base frame aluminum foil structure. Each of the vapor permeable liquid-flow-inhibiting thermal barriers may have a first layer made of a hard non-porous hydrophobic non-woven fiber, and a second outside, external layer made from a hydrophobic cellulose fiber. The second layer forms a limiting surface barrier for the first layer.

Abstract: The present disclosure relates to battery plates which are useful in optimizing the power and energy density of a batter assembly by having discrete active materials. The present disclosure relates to a battery plate having: a) a substrate having a first surface opposing a second surface; b) one or more active materials disposed on the first surface, second surface, or both the first surface and the second surface of the substrate; and wherein the one or more active materials include two or more discrete active material regions.
