Abstract: A system for tracking a location of a movable object can include a tracking device mounted to a collar. The tracking device can be configured to track its location using at least one of a global positioning system signal, a Bluetooth signal, and a Wi-Fi signal. The system can include a middle man charging mechanism. The middle man charging mechanism can be configured to receive electrical energy from a base station charging device. The middle man charging mechanism can be configured to store the received electrical energy. The middle man charging mechanism can be configured to couple to an external charging interface of the tracking device to recharge the battery included in the tracking device while the collar is worn by the movable object. The tracking device can also be configured to transmit information corresponding to the location of the tracking device to an external computing device.

Abstract: A wearable tactile display device is disclosed wherein vibrating stimulation pins are located close to each other by means of underlying vibratory actuation piezoelectric bending elements arranged in a cantilever configuration partially overlapping over each other. Optionally, the plane in which the tips of stimulation pins protrude may be a curved surface providing with the ability to comply with a curved human body part such as a finger. Vibratory stimulation can be achieved at close spatial resolution by advantageously reducing the space between adjacent stimulation pins through their ability to engage with different adjacent piezoelectric cantilever bending elements when they are placed at different planes and at additional closer spatial resolution when they are placed at an angle to each other. The programmable controller employed in order to program the pattern of stimulation pin vibrations can be used for generating different amplitudes and frequencies of vibration.

Abstract: A high precision positioning device includes an end effector and a platen spaced therebelow for receiving a workpiece. One of the end effector and the platen is moveable in the X-Y plane. One of the end effector and the platen is moveable in the Z direction. The device includes senors for sensing the position of the end effector in the X, Y and Z directions relative to the platen. The apparatus includes a control system for controlling the movement of the end effector relative to the platen and adjusting the position of the end effector relative to the X. Y and Z position as sensed by the sensors. Preferably the platen is generally parallel to the X-Y plane and the Z direction is normal to the platen. Preferably the control system uses a position, velocity and acceleration control system for controlling the movement in the X and Y direction and an impedance control system for controlling the movement in the Z direction.
