Abstract: A reversible positioning device contains a piezoelectric actuator (10) of a linear contact type urged against a rotary or a linear type movable element (20). The actuator is equipped with two sets of electrodes: (90), (110), (80) and (100), (120), (80) respectively. The control unit supplies electrical impulses to either one of the theses sets of electrodes to initiate periodic oscillations of the actuator (10) causing elastic compressions of the movable element (20) and subsequent movements in either one of the opposite directions. One particularly useful application is in the movable arm of the disk drive data storage system such as a CD-ROM or alike. Extreme accuracy of positioning of a readout head and a low inertia allow for fast response time approaching 2 msec. a novel control method is in supplying a higher voltage from a control unit for the longer forward motion of the positioning device followed by a shorter back movement due to lower voltage. That control method increases the positioning accuracy even further to as low as 0.2 microns.

Abstract: A piezoelectric motor (100) of a linear contact type contains one or more actuators (150 and 151) placed about a rotor (140). Each actuator (150) contains at least one piezoelectric vibrator (120) with a working end (133) urged against the rotor (140). Periodic oscillations of each vibrator (120 and 121) cause compressions of the rotor (140) not exceeding its natural elastic compression limit so after its compression the rotor (140) fully restores its initial cylindrical shape. Such elastic compressions ensure longer operational life of the motor. In another embodiment, each actuator (200) has a laminated design with at least two vibrators (221 and 222) separated by an isolator (223). The isolator extends beyond the vibrators and has appropriate hardness to engage with the rotor (240). A rotor of laminated design is also described to achieve the optimum hardness relative to the hardness of the actuators. The hardness of the vibrator edge is about 5x10 N/cm and is much higher than the hardness of the rotor being about 2x10 N/cm . A disk drive is described as one of the most advantageous applications of the motor of the invention to drive optical and magnetic disks such as in a CD-ROM drive etc.

Abstract: The disclosure relates to particle heaters for heating solid particles to store electrical energy as thermal energy. Thermal energy storage directly converts off-peak electricity into heat for thermal energy storage, which may be converted back to electricity, for example during peak-hour power generation. The particle heater is an integral part of an electro-thermal energy storage system, as it enables the conversion of electrical energy into thermal energy. As described herein, particle heater designs are described that provide efficient heating of solid particles in an efficient and compact configuration to achieve high energy density and low cost.

Abstract: Disclosed is a counterbalance system for moving a payload and a method for counterbalancing the payload. The system and method comprise a resilient member that is in communication with the payload to be moved and two resilient members that are in communication with either end of the first resilient member. An actuator is in communication with the first and third resilient members and a payload arm, attached to the payload, is in communication with the first and second resilient members. The resilient members may be compressed and relaxed during movement of the actuator and the payload arm so that energy may be transferred between the system and the payload to counterbalance the weight of the payload.
