Smartphone case having reconfigurable input control features for controlling smartphone apps

Publication number: US10848604B2

Application number: US16/721,566

A smartphone case for holding and protecting a smartphone, while also having various features for controlling an app, such as a video game running on the smartphone. The smartphone case includes a case body having a case back, and a case side wall that extends circumferentially around the case back, including four corners. The case side wall also extends above and below a smartphone held by the case, thereby forming a front rim and a back rim. The case side wall also includes corner connectors configured to connect with a swappable input control module. The case back also includes dedicated controls, and at least one recess for storing a swappable control module while not in use. A long side of the case side wall includes a left bumper and a right bumper. An app provides a GUI for assigning the dedicated and swappable controls for an app to be controlled.

Battery management system for battery banks with a small number of cells

Publication number: US10847835B2

Application number: US15/841,288

A battery management system monitors and controls the state of charge of a plurality of battery cells with a single data transceiver line. A sense board coupled to each cell monitors the battery cell voltage and temperature and reports the cell voltage in series, according to the location in series. A data request signal is sent by the control device of the battery management system through the single data transceiver line to initiate battery cell data transmission. The first battery cell in the series sends the first battery data upon receiving the data request signal and each subsequent battery cell in the series sends their respective battery data after a predetermined delay time set by two quaternary bits formed by a pair of voltage dividers. The state of charge may be displayed in real time on a graphical or numerical display.

Load sharing bone plate

Publication number: US20180064480A1

Application number: US15/807,585

A load sharing bone plate has a plurality of directional apertures configured to effectively support and share the load with a fractured bone to promote healing. A load sharing bone plate may have a body portion that is thinner and be configured to be secured with smaller fasteners than conventional bone plates. A load sharing bone plate has a plurality of directional apertures, configured to direct a fastener is a specific orientation, such as in an oblique angle to the length and/or in an oblique angle to the width of the bone plate. A load sharing bone plate may be configured with a load sharing extension on at least one end that is configured to reduce stress concentration at the end of the bone plate. A load sharing extension may have a tapered thickness and/or width from the body portion to the extended end.

Angle adjustable crutch handle

Publication number: US10835446B2

Application number: US16/551,077

A crutch handle is positionably adjustable to a crutch at an offset angle to provide an ergonomic position of a user’s hand. The crutch handle has a curved adjustment adapter on both a first and second end of a handle-grip portion of the crutch handle. A fastener slot extends through the first and second adjustment adapters to allow a fastener to extend though and secure the handle to the crutch at an offset angle. The handle-grip has a fastener opening on at least one of the first or second ends to allow the fastener to be positioned along the handle-grip portion of the handle. A conventional crutch may be adapted with this angle adjustable crutch handle with the fasteners being in apertures that are aligned across the crutch support.

Personal flotation device

Publication number: US10814943B1

Application number: US16/200,218

A horseshoe shaped personal flotation device is buoyant and can be used in a number or positions to float a person on the water and retain a beverage. The horseshoe shaped flotation device has a left and right armrest that extend out from an arced shaped closed end and dual cup holder, on the extended end of the armrest, has an cup cylinder to retain a beverage in the vertical orientation and an end cup holder to retain a beverage in an orthogonal orientation to the cup cylinder. The flotation device can be used in an underarm-floating configuration and a beverage can be retained in the cup cylinder, or used in a saddle, hammock or back floating configuration with a beverage retained in the end cup holder. The flotation device can be extended to spread the left and right armrest apart for some flotation methods.

Steam cooking apparatuses with invertible steaming insert baskets and controlled venting lids

Publication number: US10765250B1

Application number: US16/035,638

A steam cooking apparatus containing a water retaining cooking vessel with a vertically invertible insert basket and associated vertically adjustable lid which clamps the food stuffs in exact position when insert basket is inverted. Steam cooking apparatus includes an interior pedestal mount, removable insert basket handle, and lid fitting atop of the exterior cooking vessel having multiple specific venting apertures.

Valve-coupler actuating system

Publication number: US10760708B1

Application number: US16/256,922

A valve-coupler system has a lever that extends under a length axis of the valve body to enable one-handed operation. The valve-coupler body has an opening that is configured over a valve stem and a seal actuator having a lever that can be rotated about a pivot with a single hand to create a seal around the valve stem. Additionally, a valve-coupler may have a gas inlet valve that can be activated by the same single hand to open the valve and allow gas to flow into the valve stem. The inlet valve may be configured in line with the lever whereby the inlet valve is opened when the lever is rotated about the pivot to contact the inlet valve. The inlet valve may be configured on the valve body for manipulation by a user’s finger or thumb. The inlet valve may be on the top of the valve body.

Organic toothpaste

Publication number: US10758474B2

Application number: US16/345,242

An organic toothpaste is a Pickering emulsion having a particle stabilizer bound in the interface between the continuous, phase and dispersed phase of the emulsion. The particle stabilizer prevents the dispersed phase from coalescing and phase separating. The emulsion may include glycerin and water to form the emulsion and particles, such as erythritol and/or rice powder as the stabilizer. An organic toothpaste may be certified USDA organic and contain no more than 5% by weight of components list of allowed substances, found in the Electronic Code of Federal Regulations, Subpart G published on May 24, 2018. An organic toothpaste may include a foaming component such as saponin, soapbark, decyl glucoside or Quillaja saponaria. In addition, an organic toothpaste may include a natural sweetener such as agave, xylitol or erythritol.

Regenerative fuel cell

Publication number: US10749201B2

Application number: US16/056,116

A regenerative fuel cell produces hydrogen that is stored in a reservoir on the storage side of a membrane electrode assembly when operating in a hydrogen pumping mode and this stored hydrogen is reacted and moved back through the membrane electrode assembly to form water when operating in a fuel cell mode. A metal hydride forming alloy may be configured in the hydrogen storage reservoir and may be coupled to the membrane electrode assembly. An integral metal hydride electrode having a metal hydride forming alloy may be configured on the storage side of the membrane electrode assembly and may have a catalyst or an ion conductive media incorporated therewith.

Self-rightening post system

Publication number: US10745931B1

Application number: US16/791,961

A self-rightening post system is configured to secure a post in a casing in a desired or vertical orientation and to self-righten the post upon the removal of a deflecting force, such as from a car or lawnmower. A self-rightening post system utilizes a plurality of adjustable retainer assemblies that are configured around the post and coupled to a collar. Each of the adjustable retainer assemblies has an adjustment extension with a threaded portion in the collar to change the compression of a spring extending therefrom toward the post. A post flange may be coupled to the post end of the spring to provide a planar surface for exerting a retaining force on the post. The collar is configured over a casing and configured to rotated with respect to the casing. Retainer extensions extend from the collar down along the casing to secure the collar in position.
