Abstract: The cable embedding device is used to install a cable, such as a copper cable, together with filler material within a void trenched into the surrounding land area. The cable embedding device has a hopper, and a chute extending from a lower end of the hopper. The chute includes a plowing edge attached to a leading edge of the chute. A tube is connected to the device inside the hopper and extending along a major axis of the chute. An arch is formed at a lower edge of the chute.

Abstract: A portable and programmable biofeedback system which senses a physiological variable, such as heart rate, and both displays the physiological variable in a visual display in real time and activates and deactivates a user prerecorded voice-message upon reaching a user-programmed threshold value for the physiological variable measured. The system is especially useful in the field of behavior modification which require that the patient have reliable access to his or her behavior modification techniques upon onset of the symptoms associated with a diseased behavior.
