The synchronism or tracking between two analog signals is compared by a cuit arrangement having two inputs to which these analog signals are applied. A comparator circuit compares the two signals and provides a trigger or energizing signal to a switch which in turn produces an error signal when the two compared signals deviate from each other to an extent larger than a predetermined limit. One input is connected to the comparator circuit through a heterodyning circuit wherein the respective analog signal is heterodyned by a heterodyning signal which varies in its polarity. The comparator circuit includes a polarity detector which provides a signal signifying a positive or a negative difference between the amplitudes of the two polarity signals. A discriminator circuit is operatively connected to the comparator to provide a switch energizing signal when the difference signal does not have any zero transitions or passages with the frequency of the heterodyning signal.

Evaluating a real estate transaction based on preliminary data about the transaction. An evaluation system employs a transaction evaluator software module that can receive input about a customer and a type of financial product. The transaction evaluator software module also has access to a variety of data sources defining parameters for the investing institution. When the transaction evaluator receives input for a customer, it retrieves the relevant parameters for investing and performs a series of calculations to determine the likelihood that the customer's transaction will be approved. The results of the calculations can be displayed to the user in a graphical format for a range of transaction values. The graphical presentation of the calculations assists the user in determining whether to proceed with the transaction.

A laser diode in the form of a chip with a heat sink connected to an electronic control circuit, is positioned in front of a light conductor for emitting light into the light conductor. The light conductor (103), such as a fiber (101) of a glass fiber cable (102), passes through a hole in the wall of a housing (100) for the electronic control circuit. The light conductor end is precisely adjusted in the Z-direction of an X-Y-Z-coordinate system, and rigidly held in the adjusted position in a bore or slot (17a) of a mounting block (17). The laser diode (10) with its chip (11) and its heat sink (12) are held in a roughly adjusted position in a milled recess (17c) of the mounting block (17) relative to the tip of the light conductor by a compression leaf spring (14) which permits an adjustment of the laser diode with its chip and heat sink in the X- and Y-direction for a precise adjustment. A displacement gripper tongue mechanism is then used for a precise position adjustment in the X- and Y-direction. After the precise adjustment the laser diode with its chip and heat sink are spot welded by a laser beam to the mounting block. Preferably, a cooling body in heat transfer contact with the heat sink forms a unitary, integral, one piece structure with the mounting block.
