Abstract: A remote adhesive monitoring system is used in connection with adhesive applied to workpieces moving along a production line. A reservoir, pump, and applicator apply the adhesive to the workpieces. A monitor control computer has an associated data processing program. A pump cycle sensor senses pump cycles. An applicator sensor senses when the adhesive is applied to the workpieces. A workpiece sensor senses the workpieces moving along the line. The monitor control uses input from the applicator sensing means and the workpiece sensor to determine an ON time per each workpiece at a predetermined speed. The monitor control uses input from the workpiece sensor and the pump cycle sensor to determine the number of workpieces per pump cycle. The monitor control calculates an ON time to TOTAL time ratio per each workpiece. The monitor control will then calculate an amount of adhesive used for the given ON time to TOTAL time ratio.

Abstract: An autofeeding low application temperature hot melt application system comprises a hot melt tank, a compact integrated auto feed, and operates at temperatures of not more than 260° F.

Abstract: A cellular telephone is provided for recovering hidden data that is embedded within an input acoustic signal. The telephone passes the acoustic signal through an audio coder of the telephone and then processes the compressed audio generated by the audio coder, to recover the hidden data. A similar telephone is also provided for identifying the audio signal from the compressed output of the audio coder. Various coding techniques are also described for hiding the data within the audio.

Abstract: A multi-location and multi-camera surveillance system includes cameras located at different locations. The cameras are selectively turned on and off by addressable control modules operatively connected to the cameras and a transceiver connected operatively to the modules, which turn off a previously on camera before turning another camera on, thereby to prevent more than one of the cameras from being on at any given time. The on-off actuation of the cameras may be achieved in a sequential fashion.

Abstract: A handheld remote control unit transmits binary coded rf address and control signals to an addressable transceiver where those signals are detected, decoded and processed to derive binary coded control signals that are coded in accordance with the brands or manufacturers of the audiovisual components that are to be controlled along with the function that is to be thus controlled for the addressed components.

Abstract: An rf PC interface transmits binary coded radio-frequency (rf) signals which are binary coded in accordance with software resident in a PC. The interface is plugged into a serial port of the PC and includes a pass-through port and an rf modulator. Also disclosed is an rf transceiver which receives and demodulates addressed coded rf signals, which are then combined with the appropriate audiovisual product remote control signals to drive an IR transmitter to produce remote control signals for the addressed audiovisual product.

Abstract: An automated appliance control system includes a unit which transmits binary coded address and function control signals along the a.c. power line to a plurality of appliance control modules connected to the power line at various locations in the home. The binary coded signals transmitted along the a.c. power line are in the form of binary rf bursts which occur before and after the a.c. power line zero crossing points.
