- the cart may be provided with means for attachment of the cart to external battery charging means, either via a cord and plug, or electrical contacts which will permit the battery to be charged when the cart is placed into a docking station or other receptacle, or the cart might simply use replaceable battery power sources.
- the UV light sources are LEDs
- one or more of the one or more power source(s) 530 may also incorporate an LED driver 540. Depending on the number of LEDs used, and whether the power source(s) are wired in series or parallel, more than one LED driver 540 may be required.
- the power source 530 may also include means for detecting when the cart is moving, such as an accelerometer or equivalent circuit, and a timer that will activate the UV light source(s) 550 for a predetermined length of time.
- the timer may activate the UV light source(s) 550 at a fixed amount of time after the power source 52 senses no motion from the wheels 520. Alternatively, the timing system will be activated once it senses initial motion from the wheels 520.
- the handle 510 includes LEDs at each end of the handle pointing towards each other. This particular embodiment also includes one additional LED at each end of the 90-degree turn in the handle each pointing towards the 90-degree turn.
- This configuration is merely exemplary; the skilled person will be able to position the UV light sources at different places within the handle, and also around the basket area to cover any surface subject to contamination, as desired and required.
