Abstract: A thermal cycling device consisting of a plate containing a plurality of wells to hold liquid and a lid that covers the plate and contains a number of “pins” that insert into the wells of the plate to control the temperature of the sample in the well. Biological, chemical or other samples are placed into the wells of the plate and the lid is placed on the plate with the pins inserted into or in the proximity of the sample. The lid, the outer surface of which may be copper clad and in direct contract with the pins, is heated or cooled, rapidly and uniformly heating or cooling the biological samples. The temperature of the sample can be rapidly and uniformly cycled and is particularly useful for the amplification of DNA via the polymerase chain reaction.

Abstract: The absence or shortage of a heat transfer medium can be detected without any time lag. While the medium is circulated through a water jacket and an exhaust gas heat exchanger 9 which receives heat from the exhaust gas, the heat generated by the engine 2 can be recovered. A first sensor TW1 is provided at a waste heat recovering location in a circulation path 12 of the medium. A second sensor TW2 is provided at the downstream of the sensor TW1. When the medium is absent, there is developed a difference in the temperature measurement between the sensor TW1 and the sensor TW2 which is greater than a reference level. A heat transfer medium shortage signal is outputted when a difference in the temperature measurement between the first sensor TW1 and the second sensor TW2 exceeds the reference level.

Abstract: A thermal treatment system for thermally treating a sterile medium is controlled via a foot actuated switch to thermally treat the sterile medium to a desired temperature and/or form (e.g., slush). The thermal treatment system includes a basin recessed in a system top surface, while a surgical sterile drape is placed over the system and within the basin to form a drape container for containing the sterile medium. The basin may be configured to cool the sterile medium and form sterile surgical slush, or heat the sterile medium to provide warm sterile liquid. A dislodgment mechanism may be employed within a cooling basin to manipulate the drape and dislodge frozen pieces of sterile medium adhered to the drape. Information pertaining to the sterile medium and system operation may be displayed on a system display that has dimensions sufficient to provide visibility of the information to users located within extended ranges from the system.

Abstract: A heating, ventilation and air conditioning (HVAC) device (104) which includes both heating and cooling operating modes provides an easy-to-use interface (110) for selecting the operating parameters of the device (104). The interface (110) allows the input of a setpoint temperature at which the HVAC device (104) conditions the ambient temperature of a space (102). A mode switch-over algorithm (200) uses the setpoint temperature, the sensed temperature from the conditioned space, and prestored threshold values that depend on the device's operating capacities, to determine when to change the device between heating and cooling modes. Also, within each of the respective modes, a heating (300) or cooling (400) algorithm controls the engaging and disengaging of the heating and cooling elements of the device (104) to maintain the temperature of the conditioned space (102) within a desired comfort zone.

Abstract: A method is provided for treating wafers on a low mass support. The method includes mounting a temperature sensor in proximity to the wafer, which is supported on the low mass support, such that the sensor is only loosely thermally coupled to the wafer. A temperature controller is programmed to critically tune the wafer temperature in a temperature ramp, though the controller directly controls the sensor temperature. A wafer treatment, such as epitaxial silicon deposition, is started before the sensor temperature has stabilized. Accordingly, significant time is saved for the treatment process, and wafer throughput improved.

Abstract: A thermostat for control of an AC-operated HVAC unit (or a unit providing only heating or only cooling) is provided with load activation detection sensing for increased reliability of latching relay activation. The thermostat includes a sensing transformer in series with the heating or cooling load (or both, if both are in the system), so that, when activation of the load is called for by the thermostat, current flows in a primary winding of the transformer, inducing a current in the secondary winding. A voltage derived from the current in the secondary winding is sensed by the thermostat controller and used to determine whether the heating or cooling load has been properly activated or deactivated. Sensing of the AC power source in the HVAC unit may also be provided, so that the controller can confirm that the absence of the voltage derived from the current in the secondary winding is actually due to the state of the latching relays rather than to a failure of the AC power source.

In a preferred embodiment the gradient block is integrated into a thermal cycler used for nucleic acid amplification reactions.

Abstract: A controller for an air conditioner is provided wherein an operation mode is not unnecessarily changed in accordance with variations in temperature. When room temperature t is in a range of T+3.0>t.gtoreq.T+1.5, and when a timer expires (steps 212, 214), it is determined whether the room temperature has a tendency to fall (step 218). When the room temperature has a tendency to fall, it is predicted that the room temperature will be in an observing region although the operation mode is not changed. For this reason, the current operation mode is kept. On the other hand, when the room temperature does not have a tendency to fall, a cooling mode is set (step 210). Further, when the room temperature t is in a range of T-3.0<t.ltoreq.T-1.5, and when the timer expires (steps 222, 224), it is determined whether the room temperature has a tendency to rise (step 228).
