A temperature control system includes a fluid chiller, an air dryer, and a plurality of test stations positioned at remote locations from the fluid chiller and the air dryer. The fluid chiller is configured to generate a chilled fluid stream. The air dryer is configured to generate a dry air stream. Each local test station includes a heat exchanger and thermal control unit. The heat exchanger is configured to selectively cool the dry air stream with the chilled fluid stream to generate an output stream. The thermal control unit is configured to control distribution of the output stream to a local test site.

System and method for controlling temperature at test sites

A device under test cooling system has a refrigerant line and a fluid line extending through a plurality of successively arranged heat exchangers. A digital scroll compressor has an intake for providing the refrigerant mixture to the compressor and a discharge connecting the compressor to the refrigerant line to provide the refrigerant mixture to the heat exchangers. The compressor includes a plurality of scroll elements between the intake and the discharge for compressing the refrigerant mixture. The compressor includes a valve configured to separate the scroll elements when in an open position to allow refrigerant to flow freely between the intake and the discharge. When the valve is in a closed position, the scroll elements compress the refrigerant. A controller is configured to switch the valve between an open and closed position based on a set duty cycle.

System and method for device under test cooling using digital scroll compressor

A temperature control system for controlling a temperature of a device under test includes a fluid source and a cooling device reducing a temperature of the fluid supplied by the fluid source and outputting the fluid having the reduced temperature to a device under test. A filter is positioned between the device under test and the cooling device to filter out ice particles that lead to significant charge generation in order to prevent the device under test from being subjected to high voltages as a result of static charge generation.

Temperature system having an impurity filter

An environmental chamber system and a method for testing a device under test (DUT) include an environmental chamber in which the DUT can be tested. A temperature sensor senses temperature of the DUT, the temperature sensor generating a signal indicative of temperature of the DUT. A controller receives at least one input signal related to at least one of temperature and humidity in the chamber and the signal indicative of temperature of the DUT and provides at least one control signal for adjusting at least one of temperature and humidity in the chamber, such that the temperature of the DUT is not below a dew point of an environment in the chamber in a region of the chamber near the DUT, such that condensation in the environment in the chamber in the region near the DUT does not occur.

Environmental test system and method with in-situ temperature sensing of device under test (DUT)

A system and method for manipulating image data is disclosed. Generally, the system and method identifies useful grey-levels within an input image. The image is then scaled based upon the identified useful grey-levels.

Signal intensity range transformation apparatus and method

A portable display unit includes a serial port to connect to a device such as a vacuum network controller, cryopump, turbomolecular pump, gauges or compressor. In particular, the display unit can be plugged and unplugged to devices of different types. The portable display unit includes a display and control keys for programming, controlling and monitoring the functions of a device. The device accessible to the display unit includes a display interface having software code and files to interface with the display unit. Accordingly, the portable display unit can be used with any device having software code to interface with the display unit. The software code generates, refreshes and communicates menus to the portable display unit to provide graphical interface of the device's functions. The portable display unit further includes inner and outer hand grips so that the display unit can be held by hands of different sizes. The hand grips allow user with different hand sizes to firmly hold and navigate the display using control keys with fingers.

Remote display module

A vacuum network control system includes a vacuum network controller hub communicating over a public high-speed network, where the hub has an address registered with respect to the non-local network and communicates over a first local high-speed network. Vacuum network controllers (VNCs) communicate with the hub over the first local network. Each VNC has a dynamically assigned local address and communicates with at least one component intrabus module over a second local high-speed network. Each module has a dynamically assigned local address and further communicates with one or more monitor and control end units over a local device network. Each monitor and control end unit has a dynamically assigned address. Monitor and control end units include taps, which provide at least one of analog, digital or serial I/O, and components, for example, vacuum pumps. Device addresses can be dynamically assigned based on unique identification information sent by the device upon the device's initialization, where the device's assigned local address is transmitted back to the device in response.
