Abstract: Disclosed herein is a bridge abnormality sensing device including: a pair of vibration sensors installed in an upper structure of a railroad bridge supported with a plurality of bearings, the pair of vibration sensors being provided for two of the bearings arranged in a width direction; a detector circuit configured to output a damage detection signal based on a difference between output signals of the pair of vibration sensors; and an output circuit configured to receive the damage detection signal and notify an external device of any structural damage detected from the railroad bridge. The vibration sensors are vibration power generators that generate power in a frequency range of abnormal vibration resulting from the damage. Power to drive the detector circuit is supplied from the vibration power generators.

Abstract: An input device of the present disclosure has a stationary part, an operation input part that is provided above the stationary part, and is movable with respect to the stationary part, a detector configured to detect information regarding operation of the operation input part, and an attachment part provided in the stationary part so as to project downward from a second surface of the stationary part. The attachment part has a holder and a coupler configured to couple to the stationary part. A holding force maintaining a state where the holder is attached to an object is smaller than a coupling force between the coupler and the stationary part. When a force is applied to the holder from above, the holding force of the holder allows the holder to be fixed to the object.

Abstract: An input device includes a housing, an operation unit, a vibrating body, a piezoelectric element, a picker, and a signal processing unit. The operation unit is movable relative to the housing. The vibrating body has elasticity. The vibrating body includes a first end partially fixed to the housing, and a second end provided so as to be vibratable. The piezoelectric element is provided to the vibrating body. The piezoelectric element is configured to convert vibration energy of the vibrating body into electrical energy as the vibrating body vibrates. The picker flicks the vibrating body to allow the vibrating body to vibrate in conjunction with the operation unit. The signal processing unit is configured to receive power generated by the piezoelectric element to operate and transmit, through wireless communications, detection information to be generated as the operation unit moves.
