Abstract: One aspect is a detent hinge device having a first cam component with at least one spline and an axial cam face, the first cam component having a root diameter and an outer diameter. A second cam component has at least one spline and an axial cam face, the second cam component having a root diameter and an outer diameter. Each of the first and second cam components are aligned on an axis, wherein the cam faces of the first inner and first outer cam components face each other. An axial spring acts on the first cam component forcing it against the second cam component. An axial retention element securing each of the first and second cam components and axial spring on the axis. A first mounting bracket has splines on an inner surface. The first mounting bracket contains the first cam component such that the splines of the first mounting bracket engage the splines of the first cam component thereby transferring torque from the first cam component to the first mounting bracket via the splines.

Abstract: One aspect is an inertial lock friction hinge, including a shaft assembly having a shaft assembly recess and a friction assembly having a friction assembly recess. The shaft assembly and the friction assembly are rotatably coupled for relative frictional rotation. The hinge includes a restraining component positioned within the hinge such that when the hinge is in an unlocked condition the restraining component is not engaged with both the friction assembly recess and the shaft assembly recess so that the shaft assembly and the friction assembly are allowed to rotate relative to each. The restraining component is positioned such that when the inertial lock friction hinge is in a locked condition the restraining component is at least partially engaged with both the friction assembly recess and the shaft assembly recess so that the shaft assembly and the friction assembly are locked and prevented from relative rotation by the restraining component.

Abstract: Instrument free “plasticware” is provided that enables multi-step molecular reactions in a diagnostics context. A hollow plunger that is movable within a surrounding tube defines a reaction chamber inside the plunger. By moving the plunger to different positions in the tube, a sample can be collected, then the sample can be washed, and finally the reaction chamber can be sealed to perform diagnostic reactions on the sample. The juxtaposition of large sample collection/washing volume with small reaction volume allows one to conduct a wide range of diagnostic assays including a LAMP (Loop mediated isothermal amplification) based saliva test in a small, portable self-contained device. Applications include Molecular diagnostics for health applications (including COVID19 test), Environmental Monitoring, Disease surveillance, and Veterinary health.

Abstract: One aspect is a wrap spring clutch with a rotatable input and a spring having a first and a second end and having an equilibrium state and a flexed state, the spring engaged with the input through one of the first and second ends such that the spring rotates with the input and with an input torque transmitted exclusively through one of the first and second ends when the input rotates. A damper mechanism is engaged with one of the first and second ends such that the damper mechanism causes the spring to change from its equilibrium to its flexed state when the input transitions from stationary to rotational, and such that the damper mechanism allows the spring to change from its flexed to its equilibrium state when the input transitions from rotational to stationary. A rotatable output is positioned relative to the spring such that the output synchronously rotates with the input when the spring is in its flexed state and rotates independently of the input when the spring is in its equilibrium state.

Abstract: One aspect is a detent device with a first hub having an axis and comprising a first feature having both a radial and an axial dimension relative to the hub axis, and having a first hub connection portion. A second hub is located co-axially outside the first hub and comprises a second feature having both a radial and an axial dimension relative to the hub axis, the second feature of the second hub touching the first feature of the first hub when the features are aligned. The second hub has a second hub connection portion. The first and second features have complementary mating geometries. The detent device is configured such that when relative movement is provided to the first and second hub connection portions, a circumferential strain energy of the second hub changes, providing a variable force between the two connection portions depending on their relative position.
