A forward extending hollow glare reducing enclosure blocks glare on smartphone or wearable action camera viewing screens. The glare reducing enclosure totally blocks glare on the display screen in real-time, moment to moment. To protect the camera from weather elements, the camera is inserted in a holding clamp. Optionally, a user-worn headband holds a forward extending clamp and glare preventing enclosure, supporting a wearable action camera spaced apart from the viewer user. The user can record videos and stills during athletic or recreational activities, such as mountain climbing or skateboarding. The smartphone camera or the wearable action camera is activated by hand-controlled Bluetooth/Wi-Fi signals or via voice activation software. The action camera and glare reducing enclosure are positioned whereby the eyeball of the user, in combination with the wearable action camera, and the display screen jointly and simultaneously move, see, and record in any direction together.

A lubrication distribution assembly is provided. The lubrication distribution assembly includes a lubrication metering device, which includes a piston. The lubrication distribution assembly also includes a sensor and a controller. The sensor automatically detects a piston stroke length of the piston over at least two movement cycles of the piston. The controller receives the piston stroke length from the sensor, sets an operating point of the piston based on the piston stroke length, and controls the lubrication metering device by utilizing the set operating point.
