International Classification:

G02B 6/38

US Classification:

385 58, 385 53, 385 55, 385 60, 385 70

Abstract:

The present invention is directed to systems and methods that couple together optical devices in a manner that prevents damaging light from escaping the coupling except through the devices. In order to prevent damaging light from coming into contact with the user, the present invention obscures the source optical device by using at least one moveable gate to prevent damaging light from being transmitted outside of the coupling until such time as the target optical device is fully inserted into the coupling, thereby preventing light that could potentially damage a person from escaping the system except through the optical device.

International Classification:

H01R 33/00

US Classification:

439 34, 320109, 36167941

Abstract:

The present invention is directed to a system and method which establishes physically fixed charger stations that work in conjunction with a medical cart, such as an ultrasound cart. The medial cart contains a power supply, such as a large battery, with the capacity to keep the system going for a full day's use. Each docking station provides a fixed location for one or more carts and allows each cart to plug directly into a source of premises power. The docking stations allow the plugged-in cart to recharge while the cart is not in use. In one embodiment, a large Class C battery capable of powering not only the medical device but its associated peripherals as well. Thus, when the cart is removed from the docking station and taken to a patient's location, the equipment on the cart can be operated without the need for plugging the cart into a wall outlet thereby eliminating the need for a long power cord. The fixed locations of the docking station also eliminates the need for hunting “misplaced” carts.
