A micromechanical mechanism (1), in particular for an horological movement (3), the mechanism including a micromechanical device including a mobile element (8) needing to be moved mechanically to trigger its operation. Included is a system for actuating the device, the actuation system including a mobile striker (16, 17, 18) configured to go from a release position (19) to a percussion position (21) in which it transmits to the mobile element (8) a momentum necessary for the release of the device, the actuation system further including a magnet (15) configured to attract the mobile striker (16, 17, 18) in a percussion position (21). Also a horological movement (3) including such a mechanism (1).

A percussive response unit, and percussion instruments with same, including a rod having a rod shaft and a first retaining element, such a first head, disposed at a first rod end and having a first head width. At least a first striker set of at least one striker is disposed along a first portion of the rod shaft and is positionable near the first head. Each striker defines an opening that is larger than the outer diameter of the rod shaft to enable at least one direction of movement. A second retaining element such as a second head is connected to the second rod end to secure the first striker set on the rod shaft. Other embodiments include percussion instruments with multiple internal resonance cavities, internal resonance members, and internal and/or external strikers.

The present invention is directed to a firefighting equipment inspection notification device that includes a main body for housing a processor that is conventionally connected to an internal memory, a timer, an input/output unit, a visual indication unit, a power source and a wireless communication unit.

A notification system utilizing a doorbell assembly in electrical communication with a sound generating mechanism (e.g., a windchime) is described to produce sound(s). In some embodiments, the system utilizes a modification of existing elements to produce the notification system. In some embodiments, the system utilizes assembled parts as part of a notification system or assembly.

A striking mechanism is for a watch or music box that includes a vibration plate with optimized actuation energy. The striking mechanism includes a plurality of cantilevered strips. These strips are each made of a material of Young's modulus E and of density ρ satisfying the inequality: $\sqrt{\frac{E}{{\rho }^3}}<0.25m\text{/}s.$
All of the strips (2) each satisfy the relation: ${\delta }_{f,b,20\mu W}\left(L\right)={\left(\frac{8U}{b}\right)}^{\frac{1}{2}}{{\left(\frac{3.515}{4\pi f}\right)}^{\frac{3}{2}}[\frac{E}{{(}^{}}}^{}$

A light-powered, electromechanical chime has a striker assembly (3) inside a bell (1). The striker assembly contains a clapper (6) and electronics, including a light collector (7) and a motor (10.) The striker assembly is suspended by a torsion element (2) attached to the shaft (11) of the motor. Light causes the motor to wind the torsion element, then the unwinding torsion element causes the striker assembly to rotate and the clapper to strike the bell.

The automated wind chime comprises a housing and a wobble arm. The housing may be suspended from a clapper of a wind chime. A motor within the housing may rotate the wobble arm when energized. The wobble arm may be unbalanced such that rotation of the wobble arm causes the housing to sway in an erratic pattern. Moving the housing in the erratic pattern may cause the clapper to strike a plurality of percussion targets within the wind chime thus producing chime music even in the absence of wind. The housing may have a novelty appearance. As non-limiting examples, the housing may be shaped like a duck, turkey, Easter bunny, Santa Claus, musical note, or flower.
