A suspension holder and a frame unit thereof are provided. The frame unit includes a main segment, a suspension segment, and a holding segment. The main segment is in an elongated shape defining a longitudinal direction. The main segment includes a selecting portion, two long lateral edges, a first mating portion, and a second mating portion, the latter two of which are spaced apart from the selecting portion along the longitudinal direction. The suspension segment and the holding segment extend from the two long lateral edges of the main segment, respectively. The selecting portion selectively geometrically corresponds with the first mating portion or the second mating portion.

The invention is an articulated funnel holder and a method, the articulated funnel holder comprising a magnetic tray supporting a J-shaped support arm that attaches at one end to the magnetic tray and at another end to a pivoting device, the pivoting device further connects to one mast end of telescopic mast to move the telescopic mast between raised and lowered positions relative to the magnetic tray, a remaining mast end removably supports a funnel ring that removably receives and supports a funnel, wherein the articulated funnel holder moves between an open operative position and compact storage position; wherein articulated funnel holder in the compact storage position places the telescopic mast and the one or more funnel rings within a storage area as defined by edges of the magnetic tray.

Various embodiments relate to a mounting bracket for supporting a light source on a magnetic wall structure, the magnetic mounting bracket comprising: (a) base having a first magnetic contact positioned on a bottom surface of the base; (b) an arm mount affixed to the base; (c) a light mount affixed to the base; (d) at least one arm pivotally fixed to the arm mount; and (e) a pad pivotally connected to an extending end of the at least one arm, each pad having a second magnetic contact positioned on a contact surface of each pad. Various embodiments further relate to a method of supporting a light source on a magnetic wall structure.

A display stand with an adjustable rear support that is movable along a base by way of a channel is provided. The rear support receives and sandwiches objects, each of different thicknesses, between and against a support lip. The rear support is orientated at an obtuse angle relative to the base. The channel is tapered, facilitating a tapered slide nut to move there along in concert with the rear support. A threaded fastener interconnects the rear support and the slide nut by way of the channel. The slide nut provides female threading engaging the threading of the threaded fastener. The rear support provides a slot that seats on a protrusion of the slide nut to provide anti-rotation functionality.

An adjustable mounting system enables a telepresence device to be easily mounted to a wall. Once the mounting system is emplaced, the area to which the telepresence device is or will be connected can be adjusted for distance with respect to the wall as well as to ensure the scaffold unit is level—without the need for cumbersome tools.

Method and system allowing more accurate detection and identification of unwanted arcing include novel processing of signal voltage representing recovered power-line current. In one implementation, arc-faults are detected based on numerical analysis where individual cycles of line voltage and current are observed and data collected during each cycle is processed to estimate likelihood of presence of arc-event within each individual cycle based on pre-defined number of arc-events occurring within pre-defined number of contiguous cycles. In another implementation, fast transient current spikes detection can be done by: computing difference values between consecutive line-current samples collected over a cycle, average of differences, and peak-to-peak value of line-current; comparing each difference value to average of difference; comparing each difference value to peak-to-peak value; and, based on calculation of composite of two comparisons, using thresholds to determine if arcing is present within processed cycle.

The present specification discloses systems, devices, and methods and uses provide a mounting system which includes rail and a bracket which is selectively secured to the rail. A bracket disclosed herein selectively and/or automatically secures or locks to a rail disclosed herein when positioned on the rail by actuating or triggering a locking mechanism disclosed herein to adopted a locked configuration. In addition, a bracket disclosed herein may be selectively removed from a rail by actuating or triggering a locking mechanism disclosed herein to adopted an unlocked configuration. The disclosed mounting systems, devices, and methods enable a device to be protected from impact and moisture exposure, enable a device to be securely mounted on a base, and/or enable a device to be quickly secured and removed from a base.

A device for wall mounting television or another display includes a wall mounting portion, a display mounting portion, and an extending/contracting portion. The extending/contracting portion includes a lower arm, an upper arm, a front bracket, a wall mounting bracket, one or more gas springs, and a linear actuator. The one or more gas springs and the linear actuator are arranged selectively to retract and extend the display mounting portion. The lower arm includes protrusions for automatically straightening a display attached to the display mounting portion. The display mounting portion and the extending/contracting portion together include a mechanism for automatically adjusting azimuth of the display mounting portion to a pre-set position when the display mounting portion is lowered into a viewing position. The mechanism for automatically adjusting azimuth may include a set screw and a biasing spring.

Provided is a display apparatus including an image forming device configured to form an image, an optical system configured to provide an output image by combining light containing an outside landscape with the image formed by the image forming device, and a driving device configured to adjust a distance between the image forming device and the optical system, wherein the driving device includes a fixed frame, a movable frame which faces the fixed frame and is movable, an actuator configured to change a distance between the fixed frame and the movable frame, and a fixing member configured to fix the distance between the fixed frame and the movable frame, wherein the image forming device is fixed to the movable frame.

A night vision goggle adapter including: a goggle mount assembly; a primary magnet generating a magnetic flux; a magnetic flux conducting unit having a first end and a second end; a first plurality of shunts; and a second plurality of shunts disposed about the goggle mount assembly; wherein the magnetic flux conducting unit may overlap the primary magnet and form a magnetic circuit for conducting the magnetic flux towards the second end of the magnetic flux conducting unit when none of the first plurality of shunts and none of the second plurality of shunts are overlapped by the magnetic flux conducting unit; and wherein the magnetic flux is shorted through one of the first plurality of shunts or the second plurality of shunts when the magnetic flux conducting unit is positioned to overlap one of the first plurality of shunts or one of the second plurality of shunts.
