Abstract: An air controlled off-loading device that provides the ability for a less mobile individual to adjust themselves in bed with or without the assistance of a caregiver as well as allowing a caregiver to boost this individual up in a bed or chair in the home setting. The device includes a rectangular pad having a plurality of attachment sites for removably attaching inflatable wedges. The attachment sites including a plurality of hook and loop fasteners mounted to the upperside of the pad. A plurality of inflatable wedges are removably secured to the plurality of hook and loop fasteners mounted to the upperside of the pad.

Abstract: Some embodiments of the present invention provide a method of cryptographically identifying and authenticating embedded devices through interaction with a distributed ledger. The device begins with a manufacturer root key and a globally unique identifier. It registers by signing a registration transaction that includes its identifier using its private root key with a digital signature algorithm and sending the resultant transaction to the distributed ledger. The ledger generates a registration root key and responds by sending this second root key back to the device. The device then uses the manufacturer root key and the registration root key to generate a child key that it uses to sign its response to the challenge proving that it possesses both the manufacturer key and the registration key. Thereafter, the device can non-interactively identify and authenticate itself to the distributed ledger by signing transactions with the derivative key.

Abstract: A machine includes a VGT and a controller. The controller monitors, based on causing the VGT to operate according to the non-dynamic control scheme, a plurality of hardware limit parameters associated with an engine of the machine. The controller determines that a hardware limit parameter, of the plurality of hardware limit parameters, satisfies a dynamic threshold for the hardware limit parameter and thereby causes the VGT to operate according to a dynamic control scheme. The controller then monitors the plurality of hardware limit parameters and thereby determines that each hardware limit parameter, of the plurality of hardware limit parameters, satisfies a non-dynamic threshold for the hardware limit parameter. The controller therefore causes the VGT to operate again according to the non-dynamic control scheme.

Abstract: Flow meters may include a body defining a fluid channel therein. At least one structure may be positioned within the fluid channel, and fixed relative to the body, that is shaped and positioned to produce a flow-induced vibration that varies according to a rate of fluid flow through the fluid channel. A method of measuring a fluid flow rate may include directing a fluid over a first structure located in a first channel, and producing a first flow-induced vibration that varies according to a rate of fluid flow in a first channel with the first structure. The method may further include measuring the vibration of a remote structure coupled to the first channel, and determining the rate of fluid flow in the first channel from the measured vibration.

Abstract: The present invention relates to a disinfecting glove device comprised of a glove body with at least one UV light. The UV light is positioned on the inside surface of the glove body. The UV light preferably emits UV light in the frequency of 150-230 nanometers during use. As a result, germs, bacteria, and viruses on surfaces touched by the inside surface of the device are killed via the UV light.

Abstract: Identity management in the present invention can include several operational steps such as identity verification by a third party, identity inquiries, and inquiry approval by the identity holder.

Abstract: A system and method for measuring concentration of oxidation ions in a solution includes a conduit that contains the solution at least temporarily, a pH sensor associated with the conduit and configured to provide a pH signal indicative of a pH of the solution, an oxidation reduction probe (ORP) associated with the conduit and configured to provide an ORP signal indicative of an oxidation reduction of the solution, and a controller configured to receive and process the pH signal and the ORP signal, wherein the controller calculates a concentration of oxidation ions in the solution based on the pH and ORP signals.

Abstract: A method of fabricating an object by additive manufacturing is provided. The method includes irradiating a portion of powder in a powder bed, the irradiation creating an ion channel extending to the powder. The method also includes applying electrical energy to the ion channel, wherein the electrical energy is transmitted through the ion channel to the powder in the powder bed, and energy from the irradiation and the electrical energy each contribute to melting or sintering the portion of the powder in the powder bed.

Abstract: An inventory tracking scaled locking canister has a housing, a closure, a commodity container positioned within the housing and releasably sealed within the housing by the closure through an electrically disengageable magnetic locking mechanism, at least one weight sensor, a processing unit, a biometric sensor, a digital display, a data storage unit, a wireless communication device, a power source, and a GPS module. The commodity container may have multiple nested frames with perforations that allow smaller byproducts of the contents of the central frame to be separated from the bulk of the contents. The weight of each frame is measured individually through one or more load cells. The biometric sensor prevents unauthorized access to the commodity container. The processing unit facilitates data collection, storage, and transmittal through the wireless communication device to a remote server. The GPS module tracks the location of the canister in case of theft.
