Pride Health Care Legend Scooter 510(k) number -- K926295 Product Code -- 89INI

#### 4. Description of Device

The Jupiter 50F electric scooter is a mobility assistive device for physically challenged people and elderly people. It is motorized by a 24V DC motor. Two or four 12 volt batteries supply electrical power.

{1}------------------------------------------------

Jupiter 50F consists of seven major components: chassis, body covers, transaxle, seat, controller, batteries, and battery charger.

The chassis is divided into three parts: the tiller, the front and the rear chassis. The front and rear chassis are jointed by two pin shafts and secured by two U-shaped pins. They can be assembled or dismantled in less than a minute without using any tools. The tiller is articulated by its upper and lower parts to provide the maximum flexibility. There is a wind shield attached to the handle bar. A unique function of this is to provide a temporary table for holding coffee cup, books, and et. A Jupiter's user can write or work with convenience.

The scooter fairing are made of high-strength plastic - PBS. They cover the chassis and tiller. Their surfaces are painted by baked paint with high finishing. A headlight is installed in the front fairing and two turning lights are in the rear. Those lights enhance drive safety greatly by providing not only signals to other vehicle drivers and pedestrians, but also by lighting road surface and obstacles to avoid collision or other accidents.

A sealed drive train is used in Jupiter scooter. No moving part is exposed. A 24-volt permanent magnetic direct current motor delivers up to 400 Watts power to the system. Motor speed is reduced through gear pairs to its desired wheel shaft speed. The inbedded differential gives the right and the left wheel different speed when the scooter makes turn. All moving parts and bearings inside the gear box are well lubricated by low-viscosity grease. The design of every part is carefully calculated and tested. Such design reduces requirement in maintenance and greatly increases its reliability and ensure a long service life.

An electric dynamic brake is attached to the motor shaft. The braking function is applied when no electric current passes its inductive coils and vanishes when speed control throttle is activated. The Jupiter can stay firmly on a slope of 9 degrees without slipping. This is a very important safety feature every scooter must have in case of sudden electric circuit failure. There is a clutch handle to release the brake locking in order to free wheeling when needed.

Two 30 Ah 12-Volt sealed gel-cell batteries are secured at the top of chassis. A full charge can make a 25 miles travel. The Jupiter 50F also can accommodate four batteries. It increases ravel distance to more than 40 miles, and lowers the center of gravity of the man-vehicle system. therefore it improves its static and dynamic stability substantially.

The battery charger is built-in with a extension cord. A user can charge the batteries conveniently wherever a power outlet can be found. It takes 6 to 8 hours to charge an almost discharged battery pack back to full capacity. In an unexpected power-off event, a couple of hours charging may get enough battery energy to allow the user to drive home.

The speed of the Jupiter scooter is controlled by two potentiometers. One is used to set up its maximum speed, and the other used to vary speed from zero to its specified maximum. The maximum possible speed is 5.0 miles per hour. The Jupiter 50F uses a Curtis controller that is widely used in powered wheelchairs and scooters all over the world, including the Shopriders.

{2}------------------------------------------------

The Jupiter 50F is a derivative from its predecessor, Jupiter 50, which is a three-wheeled scooter. The Jupiter 50 has the same aforementioned driving power train, rear chassis, electronic control system, electrical wiring system, seating, tiller, rear fairing, and wheels, except the number of front wheels and its steering mechanism.

The four-wheeled design increases the supporting area on ground surface and the swign-arm design for the wheels reduces its maximum turning angle from 900 to 31º. The Jupiter 50F users may not be able to make a sharp turning so that tip-over accidents will be greatly lessened. Our 4-wheeled Jupiter 50F did not show tip-over during its performance test and is much more stable and safer than 3-wheelers.

The Jupiter 50F is intended to be used by the physically challenged and active elderly people as a mobility assistive device. It enhance user's mobility. People who can walk but not strong enough to endue even a short distance or simply use it for convenience will find that the Jupiter scooters are ideal for them.

### 5. Similarities and Differences to Predicate Device

Our study has demonstrated that the Jupiter is substantially equivalent to the Legend 4-wheeled scooters.

#### Similarities (1).

The similarities between the Jupiter and the Legend can be identified from their appearances and performances. In principle, both scooters cab be used either indoors and outdoors, and the intended users are the physically challenged people and elderly people. The features built in the Jupiter may be easily found in those Legend.

(a). Both the Jupiter and Legend are intended to be used by physically challenged people and elderly people.

(b). Both can be used indoors and outdoors.

(c). The Jupiter 50F and Legend scooters both use a 24 volt DC permanent magnetic motor with sealed transaxle drive unit.

(d). Both use a disk-type coil-activated electric brake.

(e). The motor control boards are the same with respect to the power FET design.

(f). True regenerative and dynamic braking provide complete downhill and deceleration speed control in both scooters.

(g). Each has an industrial-typical wig-wag potentiometer, forward/reverse speed control, along with a speed limit potentiometer.

{3}------------------------------------------------

(h). The maximum forward speeds in both scooters are in the limit of 6 miles per hour specified by ANSI/RESNA.

(i). The maximum reverse speeds in both scooters are designed to be 60% of the their maximum forward speeds, respectively.

(j). Speeds of both scooters can be controlled from zero to their maximum

(k). Both scooters feature upholstered seats with removable armrests and height adjustment capability. Seats on each swivel 360 degrees.

(1). All major dimensions are similar.

(m). Each uses two 12-volt U-1 type batteries as their power source, and each uses commercially available built-in battery charger.

(n). The console on each has a battery indicator, horn switch or button, power switch, and speed limit potentiometer.

(o). The range of each is almost the same.

### (2). Differences

There are some differences between the Jupiter and the Legend. Those differences neither are substantial, nor cause any safety concerns. As matter of fact, the Jupiter have been improved by introduced some features, such as head light and turning lights, four battery option, and bigger front wheels.

| | Jupiter 50F | Legend |
|------------------|----------------------------------------------------------------------|----------------|
| Wheels | all 10" tires | two 9"/two 10" |
| Battery | optional 4 batteries | no option |
| Lights | Front light<br>Rear signal lights | no<br>no |
| Windshield/table | yes | no |
| Seat Post | Gas-filled cylinder for auto height<br>adjustment and cushioned ride | no |

To summarize the similarities and differences, Table 1 tabulates some important structure and performance data.
