A method and system of determining and displaying energy savings from an HVAC system operating in an energy saving mode. The HVAC system is operated to maintain a comfort mode temperature during a learning period. The energy consumed by the HVAC system at multiple outside ambient conditions during the learning period is determined. The correlation between a specific ambient condition and energy consumed by the HVAC system is determined. The HVAC system is run to maintain an energy saving setpoint temperature. The energy consumed by the HVAC system is determined at an ambient condition while maintaining the energy saving setpoint temperature. The energy savings are calculated as a function of the difference between the energy that would have been consumed by the HVAC system at the ambient condition based on the determined correlation and the energy consumed by the HVAC system while maintaining the energy saving setpoint temperature at the ambient condition

The invention describes a system and method for revitalizing aging skin using electromagnetic energy that is delivered using a plurality of needles that are capable of penetrating the skin to desired depths. A particular aspect of the invention is the capability to spare zones of tissue from thermal exposure. This sparing of tissue allows new tissue to be regenerated while the heat treatment can shrink the collagen and tighten the underlying structures. Additionally, the system is capable of delivering therapeutically beneficial substances either through the penetrating needles or through channels that have been created by the penetration of the needles.

The adjuvant substance can be, for example, a topical substance or a coolant. Systems are disclosed for using a topical substance to detect contact of a phototreatment device with a tissue, detect speed of a phototreatment device over the tissue, detect regions of tissue that have been treated by a phototreatment device and/or to provide other benefits to the tissue such as improved skin tone and texture, tanning, etc. Safety systems are also disclosed that ensure that a proper consumable substance and/or container is connected to a phototreatment device and/or directed to a proper target. Additionally, cooling systems and methods that utilize phase change materials for extracting heat from a light generating device are disclosed.

The invention is directed to a low-temperature cooler using dry ice as a cooling agent. The cooler has two compartments, one for the dry ice and one for chilled storage. The cooler self-regulates via an aqueous filled temperature-regulating valve to maintain a desired temperature in the storage compartment such that the products stored therein are stored at an optimum temperature. Upon achieving a predetermined temperature in the storage compartment, the valve closes, thereby maintaining the predetermined temperature in the storage compartment.

A shaver (10) includes a razor blade (20a, 20b) that cuts hairs coming into contact therewith. A heating element (26a, 26b) is bonded to the razor blade (20a, 20b). The heating element (26a, 26b) generates heat when an electric current is passed therethrough, the generated heat being directly supplied to the razor blade (20a, 20b). A battery (32) generates electric current, and electrical conductors (28, 30, 50, 52) route electric current generated by the battery (32) to the heating element (26a, 26b).

The invention relates to a method producing parts using laser sintering wherein a fusible powder is exposed to a plurality of laser scans at controlled energy levels and for time periods to melt and densify the powder and in the substantial absence of particle bonding outside the fusion boundary. Strength is improved up to 100% compared to previous methods. An example includes a relatively high energy initial scan to melt the powder followed by lower energy scans controlled to densify the melt and separated in time to dissipate heat to the surrounding part cake. The rate and extent to which the powder particles are fused together can be controlled so that each successive scan can be used to fuse the particles together in discreet incremental steps. As a result, the final dimensions of the part and its density and mechanical properties can be improved compared to conventional methods and part growth avoided.
