Dive Xtras
Dive Xtras is a manufacturer of diver propulsion vehicles (DPVs) or dive scooters in Mukilteo, Washington, United States. History Established in 2003 by Ben McGeever and Andrew Georgitsis, Dive Xtras introduced their first DPV in 2005. This DPV was innovative in that it was the first to utilize a brushless motor and electronic speed control. The combination of these features with NiMh battery technology drastically reduced the weight of DPVs at the time. In 2017, Dive Xtras introduced the use of Li-ion power tool batteries (PTBs) for their Piranha line, which became standard for their later BlackTip and CudaX scooters. Models * Sierra Std - The Sierra standard body X-Scooter is the lightest scooter in the Dive Xtras family. * CUDA 400 - NiMh version of the CUDA Fury 1150 (aka mini CUDA). * CUDA 550 - The first "CUDA". Slightly shorter than the 650. Used a 550 watt hour battery pack. * CUDA 650 - The CUDA 650 is the front runner of the CUDA models. At 53 lbs, it is a l ...

Diver Propulsion Vehicle
A diver propulsion vehicle (DPV), also known as an underwater propulsion vehicle, sea scooter, underwater scooter, or swimmer delivery vehicle (SDV) by armed forces, is an item of diving equipment used by scuba divers to increase range underwater. Range is restricted by the amount of breathing gas that can be carried, the rate at which that breathing gas is consumed, and the battery power of the DPV. Time limits imposed on the diver by decompression requirements may also limit safe range in practice. DPVs have recreational, scientific and military applications. DPVs include a range of configurations from small, easily portable scooter units with a small range and low speed, to faired or enclosed units capable of carrying several divers longer distances at higher speeds. The earliest recorded DPVs were used for military purposes during World War II and were based on torpedo technology and components. Structure A DPV usually consists of a pressure-resistant watertight casing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mukilteo, Washington
Mukilteo ( ) is a city in Snohomish County, Washington, United States. It is located on the Puget Sound between Edmonds and Everett, approximately north of Seattle. The city had a population of 20,254 at the 2010 census and an estimated 2019 population of 21,441. The current site of Old Town Mukilteo was inhabited by the Snohomish people prior to the arrival of American settlers in the 19th century. The Treaty of Point Elliott was signed in Mukilteo in 1855, opening the region to settlement. A new town was founded at Mukilteo and became the provisional county seat of Snohomish County in early 1861. The area remained a trading post for loggers and was home to other industries, but was overshadowed by Everett and grew slowly. Mukilteo was used during World War II as an auxiliary fueling facility, due to its proximity to the newly built Snohomish County Airport (now Paine Field). Mukilteo was incorporated as a city in 1947 and saw new suburban development, which accelerated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brushless DC Electric Motor
A brushless DC electric motor (BLDC motor or BL motor), also known as an electronically commutated motor (ECM or EC motor) or synchronous DC motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields which effectively rotate in space and which the permanent magnet rotor follows. The controller adjusts the phase and amplitude of the DC current pulses to control the speed and torque of the motor. This control system is an alternative to the mechanical commutator (brushes) used in many conventional electric motors. The construction of a brushless motor system is typically similar to a permanent magnet synchronous motor (PMSM), but can also be a switched reluctance motor, or an induction (asynchronous) motor. They may also use neodymium magnets and be outrunners (the stator is surrounded by the rotor), inrunners (the rotor is surrounded by the stator ...

Electronic Speed Control
An electronic speed control (ESC) is an electronic circuit that controls and regulates the speed of an electric motor. It may also provide reversing of the motor and dynamic braking. Miniature electronic speed controls are used in electrically powered radio controlled models. Full-size electric vehicles also have systems to control the speed of their drive motors. Function An electronic speed control follows a speed reference signal (derived from a throttle lever, joystick, or other manual input) and varies the switching rate of a network of field effect transistors (FETs). By adjusting the duty cycle or switching frequency of the transistors, the speed of the motor is changed. The rapid switching of the current flowing through the motor is what causes the motor itself to emit its characteristic high-pitched whine, especially noticeable at lower speeds. Different types of speed controls are required for brushed DC motors and brushless DC motors. A brushed motor can have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithium-ion Battery
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles. It also sees significant use for grid-scale energy storage and military and aerospace applications. Compared to other rechargeable battery technologies, Li-ion batteries have high energy densities, low self-discharge, and no memory effect (although a small memory effect reported in LFP cells has been traced to poorly made cells). Chemistry, performance, cost and safety characteristics vary across types of lithium-ion batteries. Most commercial Li-ion cells use intercalation compounds as the active materials. The anode or negative electrode is usually graphite, although silicon-carbon is also being increasingly used. Cells can be manufactured to prioritize either energy or power density. Handheld electronics mostly use lithium polymer batte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mouse (computing)
A computer mouse (plural mice, sometimes mouses) is a hand-held pointing device that detects two-dimensional space, two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer (user interface), pointer on a computer monitor, display, which allows a smooth control of the graphical user interface of a computer. The first public demonstration of a mouse controlling a computer system was in 1968. Mice originally used two separate wheels to track movement across a surface: one in the X-dimension and one in the Y. Later, the standard design shifted to utilize a ball rolling on a surface to detect motion. Most modern mice use optical sensors that have no moving parts. Though originally all mice were connected to a computer by a cable, many modern mice are cordless, relying on short-range radio communication with the connected system. In addition to moving a cursor (user interface), cursor, computer mice have one or more mouse button ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Touch Screen
A touchscreen or touch screen is the assembly of both an input ('touch panel') and output ('display') device. The touch panel is normally layered on the top of an electronic visual display of an information processing system. The display is often an LCD, AMOLED or OLED display while the system is usually used in a laptop, tablet, or smartphone. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers. Some touchscreens use ordinary or specially coated gloves to work while others may only work using a special stylus or pen. The user can use the touchscreen to react to what is displayed and, if the software allows, to control how it is displayed; for example, zooming to increase the text size. The touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or other such devices (other than a stylus, which is optio ...
