Abstract: Group performance monitoring systems and methods are provided. A system for monitoring a plurality of individuals engaged in an activity may include a base station, a plurality of individual monitors to communicate wirelessly with the base station, a plurality of sensors, each sensor in communication with an individual monitor, each to be coupled to an individual, and each to sense a characteristic of the individual and to transmit, during the activity, data indicative of the characteristic to the individual monitor, and a group monitoring device to communicate wirelessly with the base station. Each individual monitor may transmit, during the activity, the data to the base station. The base station may receive the data and to transmit, during the activity, a metric based on the data to the group monitoring device. The group monitoring device may display a representation of the metric.

Abstract: The dielectric slit die is an instrument that is designed to measure electrical, rheological, ultrasonics, optical and other properties of a flowing liquid. In one application, it is connected to the exit of an extruder, pump or mixing machine that passes liquefied material such as molten plastic, solvents, slurries, colloidal suspensions, and foodstuffs into the sensing region of the slit shaped die. Dielectric sensing is the primary element of the slit die, but in addition to the dielectric sensor, the die contains other sensing devices such as pressure, optical fiber, and ultrasonic sensors that simultaneously yield an array of materials property data. The slit die has a flexible design that permits interchangeability among sensors and sensor positions. The design also allows for the placement of additional sensors and instrumentation ports that expand the potential data package obtained.

Abstract: A sensor which allows dielectric measurements to be made on a high temperature product such as a molten plastic flowing in a conduit. It comprises a ceramic cylinder with an interdigitated electrode capacitor patterned into the inside wall. Uses of the sensor include continuous determination of copolymer composition and polymer viscosity (molecular weight) in a completely non-obstructive manner.

Abstract: Apparatus is provided for monitoring the bond condition of a fine aluminum wire being ultrasonically bonded to an electrode pad. The apparatus comprises a counter for generating a start and stop signal indicative of a predetermined plurality of cycles from the ultrasonic generator of the ultrasonic bonder. A stable source of pulses is applied to a second counter which is started and stopped by the start and stop signal. The count stored in the second counter is read out to a microprocessor and is indicative of the frequency of the ultrasonic generator during the bonding operation. A plurality of frequency readings are taken and measured during the formation of an ultrasonic wedge bond and this information is employed to calculate a bond quality rating which accurately predicts whether a good bond has been made or some condition exists indicating that a good bond has not been made.
