A touch-sensitive dimmer, configured to be electrically coupled to an illumination load to adjust an illuminance of the illumination load. It includes a hollow body, a power source printed circuit board assembly (PCBA) disposed inside the body, a control PCBA, and a touch-sensitive display panel, touch-sensing components and a display element disposed on the control PCBA. The display element displays changes of illumination load adjustment modes based on trigger signals generated by the touch-sensing components. The touch-sensitive display panel includes touch keys which correspond to the touch-sensing components and a display window which corresponds to the display element, and is assembled with the control printed circuit board assembly. The touch-sensitive dimmer combines touch-sensing functions and display screen functions to achieve intelligent control. By incorporating a wireless communication module, the dimmer can further achieve remote by a remote control device.

An operation device includes an operation knob that is operable by a pull-up operation and a push-down operation about a shaft and includes a front-end operation region on a front-end side far from the shaft and a rear-end operation region on a rear end side close to the shaft, a contact detection unit to detect contact of a user with the front-end operation region and the rear-end operation region, an operation detection unit to detect the pull-up operation and the push-down operation performed on the operation knob, and a determination unit that determines an operation performed by combining contact with the front-end operation region and the rear-end operation region detected by the contact detection unit and the pull-up operation and the push-down operation detected by the operation detection unit, and also determines that at least an operation performed on the rear-end operation region is invalid when the contact is detected.

A lighting device includes a light source, an auxiliary device, and a control device configured to detect toggles of a switch that controls availability of an input power to the lighting device including the light source. The control device is configured to change an operation mode of the auxiliary device based on the toggles of the switch.

A light sensing illumination device for bicycle includes a seat, a reflector, and an illumination device. The seat includes a housing space. The reflector is disposed in the seat and in the housing space, and the reflector includes a reflection curved face which is formed in a smooth arc shape with a concave face thereof facing an opening of the housing space. The illumination unit is disposed in the housing space and projects light beam toward the reflection curved face. With a smooth arc shaped reflection curved face, the light beam projected by the illumination unit is completely reflected, so as to improve the light condensing effect and efficiently enhance the overall brightness.

In a switching control device of a vehicle control device, when a vehicle is in a non-traveling condition, an operating method for a pressing operation, which is carried out with respect to a push switch in relation to a switching control for switching an operating state of a drive source of the vehicle or a power supply state to a vehicle mounted device of the vehicle, in a case that the operating state of the drive source of the vehicle or the power supply state to the vehicle mounted device of the vehicle is switched from off to on, differs from an operating method for a pressing operation in a case that the operating state or the power supply state is switched from on to off.

A system includes a relay system and a controller. The relay system includes a plurality of relays. The controller is configured to transmit a close signal to a first relay and a second relay of the plurality of relays. The close signal is configured to close the first contact and the second contact of each of the first relay and the second relay. The controller is also configured to measure a first close time between the transmission of the close signal to the first relay and a time when the first relay closes, and to measure a second close time between the transmission of the close signal to the second relay and a time when the second relay closes. The controller is further configured to determine whether an electrical weld exists in the first relay or the second relay, based on the first and second close times.
