Abstract: A method and system for an embedded software update system, which helps manufactures or vendors avoid costly product recall activities in the event their digital products have field software errors (“bugs”) or hardware problems. One aspect of the present invention is directed to an error correction system, which remotely corrects these software errors and minimizes influences of hardware problems. Another aspect of the present invention is directed to a software updating system, which is capable of updating software modules in the digital products by use of software patches. The software patch system of the present invention facilitates manufactures' transmitting software patches to the “on-the-fly” digital products to fix software errors and minimize influences of hardware problems.

Abstract: A thermostat for a HVAC system with visual display of status and operating condition. The thermostat has a power switch to select one of Heater and Cooler for the HVAC system, a light sensor (200) to sense ambient lighting, a temperature sensor (210) to sense ambient temperature, a manual temperature switch (260) to set a desired temperature for the room, a control circuit (220) to select a preferred temperature based on selection of the power switch, an illuminating outer cover (110), which at least partially covers the outside of the thermostat, which displays one of Blue and Red colors according to selection of the power switch and the ambient lighting, and a plurality of LED displays (140) arranged on a display face of the thermostat, to display one arrangement of the LEDs based on a difference between the preferred temperature and the ambient lighting.
