Abstract: An apparatus and method for measuring cavitation energy of a device placed in a cleaning bath tank of ultrasonic and megasonic cleaning systems. Probe apparatus having an array of probes positioned within the bath detects formation of bubbles at various locations within the bath that are generated by ultrasonic and megasonic vibrations applied to the bath with each probe of the array generating an electrical waveform in response to the detection of the bubbles. Apparatus coupled to each probe of the probe array analyzes the probe-generated voltages and determines cavitation energy profiles occurring on surfaces of a device located in the bath.

Abstract: Apparatus and method for assembling circuit structures in an assembly line process. The apparatus responds to a set of program instructions by selecting components in a predefined sequence from a plurality of components and aligns each selected component to correspond with an orientation defined by the program instruction set required to mount the selected component at a specific location on a circuit board. The apparatus is controlled by the program instruction set to electrically configure and program each selected and aligned component in real-time in accordance with a configuring and programming subset of the program instruction set and to install each configured component at a predefined circuit board location.

Abstract: A voice response unit for transmitting voice prompt messages to customers and for receiving messages generated by customers in response to the voice prompt message. The unit has a speech recognizer for recognizing customer commands used to control operation of the voice response unit. Apparatus interconnects a voice decoder and voice recorder with a telephone line to transmit a generated voice prompt message and to recieve a customer message in response thereto from a calling customer coupled with the telephone line. The apparatus is also coupled with the speech recognizer and responds to receipt of a customer command combined with a portion of the transmitted voice prompt message reflected from the telephone line by cancelling the reflected voice prompt message with the transmitted voice prompt message thereby enabling the speech recognizer to respond to the customer command during transmission of the voice prompt message and interrupt the voice prompt message.

Abstract: A carton for use in shipping circuit boards. The carton has a pair of side members separated by top and bottom members configured to surround a circuit board with a closed end opposite an open end for receiving the circuit board. The closed end consists of three panels with one panel positioned perpendicular to the side members and a middle panel inserted into the carton cavity parallel to one side member with the remaining panel formed at an acute angle with respect to the middle panel inside the carton cavity to engage and position a circuit board within the carton to prevent movement thereof. A segment formed at the open end across the top member to extend partially down each side member is formed such that one side section rotates with respect to a side member so that a top section may be positioned parallel to the side member with the other side section positioned across the open end to retain the circuit board within the carton.

Abstract: Apparatus and method for testing video controller devices used with a monitor terminal to generate display configurations on the terminal monitor. The disclosed apparatus and method is embodied in test apparatus arranged to prerecord a count of pixel transitions in a test pattern display intended for use in testing video controller devices. Data representing the test pattern display is applied to video controller devices to generate control signals normally enabling the video controller devices to control a terminal monitor to display the test pattern. A count of the pixel transitions generated by a tested video controller device in response to the applied data is compared with the prerecorded count of pixel transitions to determine performance of the video controller device.

The adapter is formed with an annular section abutted the tubular section that supports the tubular section within the cylindrical member cavity in electrical engagement therewith and has a projecting member formed thereon for use with a cap to secure the adaptor within the cylindrical member cavity.

Abstract: A telephone line switch actuating mechanism includes two identical parts, each having a portion which makes up a plunger, while the remaining portion is pivotally mounted for enabling the two parts to be assembled in an opposing relationship to each other into a mechanism such that depression of either plunger activates the other plunger and the telephone line switch.

Abstract: Apparatus is disclosed for mounting a display monitor on a base and for permitting and limiting the extent of tilting and rotating of the monitor. The apparatus is made up of a spherical projection extending from the bottom of the monitor and a cavity formed in the base for accommodating the spherical projection. A collar surrounds the cavity and has an annular groove for slidably accommodating a swivel ring therein. The ring and the spherical projection have mating surfaces permitting tilting of the monitor. Projecting from the top of the swivel ring are lugs for engaging slots in the spherical projection such that when the monitor rotates, the lugs in the slots force the swivel ring to rotate with the spherical projection. A pair of swivel stops extending from a side of the groove engage a tooth extending from the swivel ring, limiting the extent of rotation of the swivel ring in the groove.
