Filed: 1997-01-27
Abstract: An improved optical rotation detector for detecting optically active molecular compounds in a sample solution using: a laser diode (12) with the beam passing through an optical fiber or lens (14) to improve its quality, a reference oscillator at frequency f (18), a first polarizes (16), a specifically constructed flow cell (20) to minimize mechanical birefringence and leaking in the cell's optical windows, a second polarizes (80), and an improved detection scheme (84). The detection scheme includes a first and second photodetector for sensing first and second signals, where the first signal is light passed through the second polarizes and the second signal is light reflected off the second polarizes. A compensator circuit low pass filters the signals, inverts one signal and sums it with the other, and then notch filters off the undesired components to produce a compensated signal.  The compensated signal then drives a lock-in amplifier which is driven by the reference oscillator to sense the amplitude modulated f frequency signal. This compensated signal indicates the optical activity of the sample, yet is immune to laser power fluctuations.

IPC: F24F11/75
Filed: 1998-10-02
Abstract: An airflow rate regulating device which is installed in a vacuum unit that collects contaminants from a processing station in a controlled space. This device enables a vacuum unit to maintain a continuous suction of contaminant particles from a processing station when there are pressure variations in the controlled space. The airflow rate regulating device is mounted in a suitable cabinet 88 and connected to a vacuum source, the airflow rate regulating device has a casing divided into two chambers separated by a wall having an passageway through which air flows from one chamber to the next. Each chamber features an airflow rate regulation valve comprising a movable member extending across the flow of air passing through the casing, that can be adjusted using counterweights. When a pressure disturbance occurs in the controlled room from a door opening, or when a hose leading the contaminant source is disconnected, the airflow rate regulation valves react to maintain sufficient vacuum pressure at the contaminants source. Since the airflow rate regulating device is mechanical, its response time to pressure is nearly instantaneous.

Title: Extended support for numerical controls
Inventor: BOUCHARD JEAN-CLAUDE
IPC: G06T19/20
Filed: 1999-03-30
Abstract: A user-interface (UI) device allows the assignment of multiple parameter values to a multiple-selection of objects through a familiar UI mechanism. A multiple selection of objects is made. A object inspector is opened such as would normally be used to eater single values to be applied to properties of all the selected objects. For example, a group of graphical objects is selected and a line-weight parameter is adjusted to make the lines of the objects heavier.  According to the invention, the same type of inspector device may be used to apply multiple values by providing far the indication of a function definition instead of an explicit value in a field normally used to enter a single value. The text boxes normally used for entry of values are provided with the ability to accept symbolic notation, e.g, a string, to indicate value ranges instead of just discrete values. The UI is programmed to parse the symbolic definition and generate values for each selected object so that each object receives a value of the selected parameter independently of the other objects. In an example, an indicator of a Gaussian probability function is entered as a string with a mean and variance to specify a range. The objects receive values pseudorandomly so that each may be assigned a different value for the parameter. This avoids the need to separately assign values to a large number of objects.
