摘要： A power saving system for underwater vehicles includes a control system, a power unit and a battery. The control system controls the power unit to drive the underwater vehicle, and generates an output driving value. The control system includes a calculation unit, a three-axis accelerometer and gyro and an underwater vehicle weight value. The calculation unit creates a correspondent acceleration value by the output driving value and the underwater vehicle weight value. The three-axis accelerometer and gyro detects the acceleration of the underwater vehicle by every less than 0.5 second interval, and generates an acceleration value. The control system compares the correspondent acceleration value and the acceleration value to control the output driving value so as to save battery power and elongate the range of travelling of the underwater vehicles.

摘要： A lighting device includes a lighting unit with two arms formed on two ends thereof. The arms each include at least one reception portion. Multiple attachments each have a slide and a clip. The slide of each attachment is slidably engaged with the at least one reception portion of each arm. The clip is pivotably connected to the slide. Each clip includes a slot so as to clip a hat visor. The clip is adjustable by sliding the slide relative to the at least one reception portion. Also, the clip is pivotable relative to the slide to adjust a direction of the slot. The lighting device is able to clip to a hat visor of different shapes by sliding the slide relative to the at least one reception, and by pivoting the clip relative to the slide.
