Filed:

Jul 1, 2002

Appl. No.:

10/187304

Inventors:

Eric Bobbitt - Brentwood TN
Robert V. Burke - Madison AL
Daoshen Chen - Sunnyvale TX
Robert McCoy - Sparta TN

Assignee:

Universal Lighting Technologies, Inc. - Madison AL

International Classification:

H02H 908

US Classification:

361 42, 361 43

Abstract:

A transformer assembly and method for powering a load with a secondary fault protected isolated secondary. The fault fault path is isolated from ground allowing voltage detection of faults and the return terminal is isolated from the midpoint for multiple load connection schemes using the midpoint as a ground connection. A power control system is connected between the primary winding and the input terminal with a ground fault detection circuit connected between the fault path and the ground terminal, where the ground fault detection circuit is operable to detect a fault and activate the power control system to disconnect the source of power from the primary winding in response to detecting the fault. Also disclosed is a high frequency filter adapted to reduce the effects of high frequency transients and a capacitive reactance connected between the input terminal means and the ground terminal. The capacitive reactance is adapted to provide a ground fault path for fault signals.

International Classification:

G09G 3/20

US Classification:

345 56, 345 39, 219506

Abstract:

A disappearing interface system for a device, such as an appliance (e. g. , a cooking range) having an interactive user interface, a light-emitting device (e. g. , a LED), a microprocessor based LED fader electronic control system that uses a PWM signal to drive an A/D circuit to control the intensity (e. g. , fade in/out) of the light-emitting device.

International Classification:

F25B 1300

US Classification:

219386

Abstract:

A rethermalization cart having top and bottom sides connected together by at least two side walls. Attached to the side walls at a plurality of vertically spaced positions are a plurality of tray supports. Attached adjacent and below the tray supports and in a cantilevered out position are a plurality of heating pads at each tray support location. Each of the pads is secured so that it can be individually disconnected, removed and replaced as needed. Switches within each individual heating pad are activated by covers that are positioned over the food. The use of the covers provides a positive indication whether the food is being heating since the switches are magnetic and the covers contain corresponding magnets. Thus, by leaving the cover off there is a positive assurance that the food will remain cold.

International Classification:

US Classification:

219386

Abstract:

A rethermalization system for rethermalizing food includes (a) a food service tray having a hot dish through-opening and the through-opening having a through-opening top edge, (b) a rethermalization cart including a cart frame, a plurality of heating pads supported within the cart frame, and a plurality of vertically spaced tray supports attached to the cart frame for supporting the food service tray at a plurality of alternative vertically spaced shelf locations, and in a tray support position such that the hot dish through-opening is disposed above one of the heating pads, and (c) a food service dish positionable in the hot dish through-opening of the food service tray. The food service dish has a bottom surface for allowing heat transfer to occur from the heating pad to food in the food service dish with the tray in the tray support position, The food service dish is positionable in a heating position when the tray is in the tray support position such that the bottom surface of the food service dish is supported by the heating pad and an upper lip of the food service dish is slightly raised and out of contact with hot dish through-opening edge. This prevents heat transfer between the food service dish and the food service tray during heating of the food. The food service dish is also positionable in a serving position when the tray is supported on a planar surface such that the food service dish is supported by the contact of the upper lip with the hot dish through-opening top edge.
