Abstract: A wearable device monitoring body conditions is disclosed. The device consists of a single or plurality transducers, particularly, ultrasonic transducers, and electronic circuitry which are packaged in a low profile patch. The electronics controls a transducer or transducers for signal transmission and receiving, data processing and wire or wireless interfacing to external devices. Laying out the electronics on a flexible printed circuit which mounted along with the transducers to a bendable material, easily adaptable to the curvature of a surface enables attaching the device to curved bodies, such as a human body, for purpose of health conditions monitoring. Low profile of the devices makes it possible to be worn a round-the-clock without causing much inconvenience for a patient. Depending on the application, the transducers can be configured as fixed or movable, providing appropriate monitoring results.

Abstract: A method and apparatus are disclosed for the direct and safe teaching of a robot. The apparatus consists of a plurality of tactile sensors and electronic circuitry encapsulated in a compact enclosure, and a handle protruding from the enclosure. The handle provides an easy means for an operator to apply an external force and to act on the sensors that generate electronic signals to the robot controller. The signals, proportional to the applied force, carry information that sets boundaries for safe operations, thus protecting the operator from any harm and the robot from damage. While in the teaching mode the operator guides the robot with the apparatus to the predetermined work positions that are recorded in the controller memory. The work position recording can be handled by either activating a pushbutton or by a voice command. The recorded positions are played back when the robot operates in the work mode.
