Application number: US15/448,747

A heating/cooling system for furnishing employs an electrochemical heat transfer device. An electrochemical heat transfer device may be an electrochemical hydrogen compressor that pumps hydrogen into and out of a tank having a metal hydride forming alloy therein. The absorption of hydrogen by the metal hydride forming alloy is exothermic, produces heat, and the desorption of the hydrogen from the metal hydride forming, alloy is endothermic and draws heat in. An electrochemical hydrogen compressor may be configured between the tanks and pump hydrogen back and forth to form a heat transfer device. A heat exchange device may be coupled with the tank or may comprise the outer surface of the tank to transfer heat to an object or to the surroundings. A closed loop may be configured having two tanks and one or two electrochemical hydrogen compressors to pump the hydrogen in a loop around the system.

Tremor suppression apparatus and method using same

Publication number: US10507155B1

Application number: US16/267,216

A neuromuscular plasticity apparatus is utilized to exercise a stretch reflex circuit which can reduce tremors and improve balance. The apparatus drives a user’s extremity at a frequency to emulate the tremor. An apparatus includes a user interface that may be driven in a rotational and/or linear motion by an electric motor. The user interface may rotate about a rotational axis by a coupler bit that is interchangeable to change the offset distance. The motion may be set to substantially the same as the tremor frequency. A user engages with the user interface to drive an extremity, such as an arm, leg or head to reduce the severity of the tremor and/or improve balance. Muscle tone is improved and tremor is suppressed for a protracted period. The apparatus may be used to exercise and improve balance reflex circuits, the principle difference being the sensory neurons that are stimulated.

Tracer insert and tracer shell incorporating same

Publication number: US10436559B1

Application number: US16/164,734

A tracer insert has an upper cavity for retaining shot and a lower cavity for retaining a tracer powder compound. The tracer insert is configured for placement within the shot-pocket of a wad within a shotgun shell. The shot is placed in and around the tracer insert within the shot pocket and some shot is retained within the upper cavity of the tracer insert. A bottom exhaust port in the lower cavity allows the release of the tracer powder compound upon firing of the tracer shell. A cavity separator separates the upper and lower cavities and a flow channel may extend down from the top of the tracer insert into the lower cavity to allow a flow of air to aid in the release of the tracer powder compound. Side exhaust ports may be configured around the lower cavity to provide additional release area for the tracer powder compound.

Ultra-quiet propeller system

Publication number: US10415581B1

Application number: US16/214,063

A propeller system combines innovative strategies to create a new methodology to reduce propeller or rotor noise. The propeller is specifically aimed for ultra-quiet electrically powered aircraft for use in high proximity aviation, but its low-noise advantages will extend to other purposes. The propeller blade includes geometries, along with size and operational limitations that minimize rotational and vortex noise, vibration and span-wise air flow on the blade. To further reduce noise, the propeller provides greater relative thrust on the inboard portions of the blade than do conventional propellers and provides less than conventional relative thrust including negative thrust at the outermost portions of the blade. The propeller blade includes stepped changes in shape at calculated intervals that can reduce resonant blade vibrations and their resultant noise. This ultra-quiet propeller design can also be used for quieting hovercraft, drones, surveillance aircraft, indoor fans, wind tunnels and other applications.

Risk stratification method for a patient having a polymorphism

Publication number: US10415094B2

Application number: US15/286,597

A risk stratification method for a patient in a disease state and specifically patients presenting a tumor, includes determining if the patient is a homozygote or heterozygote and further determining the allelic expression for the patient, CC, T/C, or C/T. For patients having the cytosine methylated, they have a TIC allelic expression and patients without a methylated cytosine have a C/T allelic expression. A patient with a TT allelic expression is classified as a highest risk patient, a patient with a TIC allelic expression is classified as a second highest risk patient, a patient with a C/T allelic expression is classified as a third highest risk patients and a patient with a CC allelic expression is classified as a lowest risk patient. The risk stratification method may further include identification of an abnormal expression or mutation/function of a gene product produced by CTCF binding site 6.
