Disclosed is a zero Poisson's ratio structure including a central pillar; at least two branched connectors extending radially from a lower end of the central pillar, wherein each of the branched connectors includes: a first segmental portion extending inclinedly upwardly or downwardly from the central pillar; and a second segmental portion extending inclinedly downwardly or upwardly from a distal point of the first segmental portion, wherein the extension directions of the first and second segmental portions are opposite to each other; and each leg extending perpendicularly downwardly from a distal point of each of the second segmental portions, wherein due to a force pressing the central pillar, each of an angle between the central pillar and the first segmental portion, an angle between the first segmental portion and the second segmental portion, and an angle between the second segmental portion and the leg is variable.

In an example, the system has a mechanical isolator comprising an elastic material configured to separate the panel rail from the torque tube cause destructive interference with a natural resonant frequency of the system without the mechanical isolator to reduce a mechanical vibration of the system.

Provided are a bracket for an anti-vibration device, and a method for manufacturing the same, in which increase of weight and peeling of a reinforcing portion are suppressed. A bracket (1) has: a reinforcing portion (20) extending in a surrounding direction of the surrounding portion (10), having ends (21) in both directions of the surrounding direction, and being fixed to an outer surface of the portion (10); and ribs (30) formed on an outer circumference of the portion (10) so as to span the ends (21) of the reinforcing portion (20) in the surrounding direction of the portion (10). The portion (10) and the ribs (30) are made of synthetic resin. A method for manufacturing the bracket (1) includes a step of injecting synthetic resin serving as the portion (10) and the ribs (30) into a mold cavity where a reinforcing member serving as the portion (20) is set.

An isolation system for a light detection and ranging (LiDAR) optical core assembly is provided. The LiDAR optical core assembly comprises a polygon-motor rotating element, an oscillating reflective element, and transmitting and collection optics. The isolation system comprises a polygon-motor base element coupled to the polygon-motor rotating element and a plurality of isolators substantially fixed to the polygon-motor base element and disposed relative to each other around a spatial location determined based on a center of gravity of at least one of the optical core assembly and the polygon-motor rotating element. The plurality of isolators is adapted to mitigate acoustic noise caused by at least the polygon-motor rotating element during operation of the optical core assembly.

A bracket with an excellent reinforcing effect is provided. A bracket (1) with an opening (A) includes a body (10) and a reinforcement portion (20). The body (10) is made of resin. The body (10) includes a pair of column portions (11) and a pair of connecting portions (12, 13). The body (10) includes a plate portion (15) on at least one of the column portions (11). The plate portion (15) is provided with ribs (16 to 18) that extend from the side of the opening (A) to the bracket outer peripheral side and protrude in the opening penetration direction. The reinforcement portion (20) includes a reinforcement portion (21). The reinforcement portion (21) forms an outer peripheral face (f1) of the bracket (1). The reinforcement portion (21) is arranged so as to overlap the ribs (16 to 18) when viewed in the opening penetration direction.

A connection structure includes first and second members disposed facing each other and an elastically deformable damper, where the first and second members are connected via the damper. The damper is made of an elastically deformable material, and includes a cylindrical portion, a flange, a first vibration absorber, and a second vibration absorber. The first member includes a convex support portion and a first contact portion in contact with a first contact surface. The second member includes a concave support portion and a second contact portion in contact with a second contact surface opposite the first contact surface. Each of ribs protrudes radially outward of the cylindrical portion and extends in an axial direction. The ribs are provided alternately on an inner periphery and outer periphery of the cylindrical portion such that positions of the ribs differ from one another in a circumferential direction of the cylindrical portion.

A medication inhalation apparatus preferably formed of a single, unitary sheet of stock, includes an outer housing, movable between collapsed and expanded states, encompassing a first volume. An inner housing within the outer housing encompasses an inner or second volume. An inhaler opening to the first volume is within a wall of the outer housing at a first location. A mouth opening to the inner volume is within a wall of the outer housing and the inner housing at a second location. A one-way inhalation valve connecting the first volume and the inner volume is within a wall of the inner housing.
