Abstract: A suspension arm assembly including at least two members relatively rotatable about each other at a joint, with at least one of the joints comprising an infinite rotation joint. The infinite rotation joint allows the members at the infinite rotation joint to have unlimited rotation relative to one another. The infinite rotation joint is configured to pass at least an optical signal therethrough. The infinite rotation joint includes a stator and a rotor. At least two portions of the infinite rotation joint are separable and can automatically form a unit when adjacent arms are connected together such that the infinite rotation joint can be separated into the at least two portions. The at least two portions are configured to be automatically connected to allow the optical signal to pass therethrough once the at least two portions are engaged.

Abstract: In a liquid level monitor for use with a liquid container of a liquid-consuming device, a light source transmits a light beam into the liquid container at a non-normal angle of incidence respective to a wall of the liquid container. A photodetector is positioned in the path of one of (i) the light beam after passing through the liquid container when the light beam is not refracted by liquid in the liquid container and (ii) the light beam after passing through the liquid container when the light beam is refracted by liquid in the liquid container. In another approach, the sensor for detecting empty includes a vibrator and a vibration sensor, and an electronic processor is programmed to determine whether the liquid container is empty of liquid based on the detected vibration of the liquid container.

A light source transmits a light beam into the fragrance container at a non-normal angle of incidence respective to a wall of the fragrance container, and a photodetector is positioned in the path of one of (i) the light beam after passing through the fragrance container when the light beam is not refracted by fragrance liquid in the fragrance container and (ii) the light beam after passing through the fragrance container when the light beam is refracted by fragrance liquid in the fragrance container. In another approach, the sensor for detecting empty includes a vibrator and a vibration sensor, and an electronic processor is programmed to determine whether the fragrance container is empty of fragrance liquid based on the detected vibration of the fragrance container.

Abstract: In a structural analysis using NMR techniques, a method for gathering k-value data from frequency encoded spin echoes generated from internal volumes selectively excited by intersecting 90° and 180° slice selective and refocusing RF pulses and subjected to a read gradient for the purpose of quantifying the spatial frequency content of the selected internal volume without contamination by a FID signal, comprising: acquiring spin echo data such that the FID signal generated by imperfections in the 180° slice selective refocusing RF pulse is attenuated by the read gradient such that any remaining FID signal is spatially encoded with higher k-values than the frequency encoded k-values being recorded for subsequent structural analysis while simultaneously providing for t2 t2* and t1 contrast. Other aspects of the invention are disclosed.

Abstract: In some embodiments, a method includes receiving, at a host device, a signal indicative of an authentication request for a client device to access a resource from a set of resources. A resource confidence value associated with the authentication request is calculated based at least in part on (1) a threat confidence vector associated with at least one risk mitigation score for each threat from a set of threats and (2) a set of resource vulnerability scores associated with the resource and each threat from the set of threats. The resource confidence value is compared to a resource confidence criterion associated with the resource from the set of resources. A signal indicative of a positive authentication is sent from the host device to the client device when the resource confidence value satisfies the resource confidence criterion such that the client device is granted access to the resource.

Abstract: In some embodiments, a method includes receiving, from a client compute device and at a server, a request to access a resource. The request can include an identifier associated with the client compute device. The method can further include accessing risk information associated with the client compute device from an instance of a distributed database at the server using the identifier. The risk information is provided to the distributed database by a set of compute devices. Each compute device from the set of compute devices implements a different instance of the distributed database. The risk information can be analyzed to identify an access decision and a level of access to the resource can be granted to the client compute device based on the access decision.

Abstract: The disclosed innovation is a method for acquiring spatial frequency spectra from specific locations in a 3D sample using modifications of the current MRI techniques for localized NMR spectroscopy. The innovation in its simplest abstraction is to add the use of a read out gradient to the current NMR spectroscopy pulse sequences and record the resultant echo. These techniques generate spectra from a selected region or generate an image of the results over a region of the sample. These methods can be applied to analyzing the structure of trabecular bone as well as for analyzing or diagnosing disease in cases where there is a difference in the spatial frequency power spectrum due to physiologic or disease processes. Various embodiments are disclosed.
