An insulating cover for an L-shaped busbar includes first and second opposing longitudinal edge portions and a longitudinal groove between the first and second longitudinal edge portions. The cover is configured to wrap around the busbar in an installed position with the first and second longitudinal edge portions overlapping, with the second longitudinal edge portion adjacent and generally parallel to a leg of the busbar and with the first longitudinal edge portion in the longitudinal groove of the cover.

An adapter for changing LED light bulbs can have a threaded fitting for attachment to the pole of an existing light-bulb changer. The adapter has a body, preferably formed of a rigid material such as a rigid plastic. The body has multiple teeth to engage the spaces between the cooling fins of the LED light bulb. The light bulb can then be unscrewed from its socket and lowered using the pole and the adapter. A new light bulb can be placed on the teeth, raised, and screwed into the socket.

A twist-and-lock mounting bracket may secure a lighting fixture to a mounting surface. The twist-and-lock mounting bracket may define an aperture having features corresponding to the shape of a twist-and-lock element disposed on a housing of a lighting fixture. Accordingly, the twist-and-lock element may be configured to extend through the aperture while the corresponding features of the twist-and-lock element and the aperture are aligned. The housing may then be rotated such that the tabs do not align with the corresponding features of the aperture, and the twist-and-lock element is thereby prevented from sliding through the aperture. The mounting bracket may be secured to a junction box positioned within a mounting surface, or it may be secured to a biasing bracket having one or more second resilient members configured to engage the interior of a recessed can light, such that the lighting fixture may be secured to the recessed can light.

A gas sensor includes a metallic shell extending along a shell axis and defining a shell attaching surface that is substantially perpendicular to the shell axis; a metallic shield extending along a shield axis and defining a shield attaching surface that is substantially perpendicular to the shield axis; and a ceramic sensing element extending along a sensing element axis, the sensing element being rigidly fixed at a first axial location of the sensing element to the shell and the sensing element being laterally supported by the shield at a second axial location of the sensing element that is axially spaced apart from the first axial location. The shield is attached to the shell at an interface formed between the shield attaching surface and the shell attaching surface, thereby accommodating misalignment between the shield axis and the shell axis. A method of making the gas sensor is also provided.

The present disclosure discloses an integrated micro/nanogenerator and a method of fabricating the same The integrated micro/nanogenerator has a structure comprising a conducting layer, a PET layer, a PDMS layer, a micro-nano hierarchical PDMS array and a metal film layer, the conducting layer being manufactured on a surface of the PET layer, the PET layer being made of polyethylene terephthalate; the PDMS layer being made of polydimethylsiloxane, and the micro-nano hierarchical PDMS array being manufactured on a surface of the PDMS layer. The method comprises steps of: 1) fabricating a micro-scale structure on a substrate through a combination of lithography and chemical etching or physical etching; 2) fabricating a nano-scale structure with high density and high depth-to-width ratio directly on a surface of the micro-scale structure through a mask-free optimized deep reactive ion etching process; 3) using a PDMS casting film transfer process by adjusting and controlling process parameters, by means of using the mold of mirco-nano hierarchical array structure as a template; 4) fabricating a conducting layer on a surface of the PET layer by using an evaporation or sputtering or chemical vapor deposition process; 5) bonding the PDMS layer and the PET layer through high temperature bonding or normal temperature physical pressing; and 6) assembling in sequence and packaging the bonded structure obtained in step 5), the metal film layer, and another bonded structure obtained in step 5).

A support pin arrangement determination assisting apparatus including a display unit which displays an image including a board image, the board image indicating a shape and an arrangement of a component on the board, a position input unit through which an arrangement position of the support pin is input, a display processing unit which causes the display unit to display a figure to be superimposed on the board image, the figure corresponding to the support pin of which the arrangement position is input, a storage unit which stores three-dimensional shape data of an electronic component and three-dimensional shape data of the support pin, an interference judging unit which judges whether or not one or some of the support pins of which arrangement positions input interfere an already mounted component, and an alarm unit which announces occurrence of interference if the interference judging unit judges the occurrence of interference.

To couple light between an optical fiber and a grating coupler of a photonic integrated circuits, a mirror is provided to turn light to/from the optical fiber to allow the axis of the optical fiber to be oriented at small angles or parallel to the surface of the PIC, and lowered close to the surface of the PIC. The mirror is further configured to reshape light from a flat polished optical fiber to produce a mode field resembling the mode field of an angled polished optical fiber, to match the design angle of existing grating couplers that are designed to work with angled polished optical fibers. The mirror and optical fiber alignment structure in the optical connector are integrally/simultaneous formed by precision stamping.
