Abstract: A self-contained, universal portable beverage condition status indicator (10) has relatively large and easily visible top light dome (30) that is selectively lighted to provide an indication as to when a beverage dispenser (12) to which it is mounted is empty of beverage. Mounting is performed without any tools or alteration to the dispenser by simply inserting an elongate sensor probe assembly (50) through an inlet (22) in the top of the dispenser (12) and down to a location adjacent the bottom (16) of the hollow body (14) of the dispenser. Tooless removal is accomplished by simply slidably lifting the indicator (10) upwardly and outwardly from the dispenser (12) until it is clear. It may then be used with a newly filled different dispenser (12). The sensor probe assembly remains functional even though lower portion may be removed. Score lines (64, 70, 65, 59, etc.

Abstract: A superheat sensor (1) for sensing superheat of a fluid flowing in a flow channel (3) is disclosed. The sensor (1) comprises a flexible wall defining an interface between an inner cavity (5) having a charge fluid (6) arranged therein and the flow channel (3). The flexible wall is arranged in the flow channel (3) in thermal contact with the fluid flowing therein, and the flexible wall is adapted to conduct heat between the flow channel (3) and the inner cavity (5). Thereby the temperature of the charge fluid (6) adapts to the temperature of the fluid flowing in the flow channel (3), and the pressure in the inner cavity (5) is determined by this temperature. A first wall part (7, 14) and a second wall part (9, 16) are arranged at a variable distance from each other, said distance being defined by a differential pressure between the pressure of the charge fluid (6) and the pressure of the fluid flowing in the flow channel (3), i.e.

Abstract: The invention discloses a method to control the work of electronic thermometer by using the position of probe. The probe incased in a disposable sheath, wherein the pre-heating mechanism in the probe and the control switch is connected with the host of the electronic thermometer by wires; and by using the axial reciprocating motion of the probe to trigger the control switch to initiate the electronic thermometer. When using the invention, we use the movement for the assembling of the sheath to initiate the hearting process and measurement, to ensure that the disposable sheath is assembled on the probe, and then execute the measurement, so as to eliminate the possibility of cross infection completely. The invention also exempts the requirement for the users to the return back of the probe into the cavity after use, and brings convenience for the users: Meanwhile, the equipment structure is simple, and the machinery assembles are few by comparison, which effectively decrease the production cost.

Abstract: This adaptive environment control system provides an HVAC control system that adapts to the continually-changing thermal characteristics of the building in which it operates. The adaptive environment control system periodically estimates the thermal characteristics of the building and uses these estimates to control the operation of the HVAC system. The adaptive environment control system also periodically measures the performance characteristics of the HVAC system to obtain data with which to update these thermal characteristic estimates. These thermal characteristic estimates enable the adaptive environment control system to determine both the length of time it takes the building to heat up and cool down when the HVAC system idles, as well as the amount of time it takes the HVAC system to heat or cool the building.
