Abstract: Method and systems for optimizing acoustic energy transmission in implantable devices are disclosed. Transducer elements transmit acoustic locator signals towards a receiver assembly, and the receiver responds with a location signal. The location signal can reveal information related to the location of the receiver and the efficiency of the transmitted acoustic beam received by the receiver. This information enables the transmitter to target the receiver and optimize the acoustic energy transfer between the transmitter and the receiver. The energy can be used for therapeutic purposes, for example, stimulating tissue or for diagnostic purposes.

Abstract: Handheld power tools may be manufactured for one type of use or may be multi-purpose in that different tools may be attached to them, each driven by the same motor. The point of connection between the handle and the tool is potentially weak. This connection is strengthened by providing a handheld power tool (10) comprising a handle (30), the handle including a motor (45), a drive shaft (100), and an attachment mechanism arranged for attaching various interchangeable tools (20) onto the handle for being driven by said motor, the drive shaft including, at one longitudinal end, a first rotational connection means (120) for engagement with a second rotational connection means (130) provided on each of the various tools, wherein the power tool is configured for the sliding, of the various tools onto the handle, in a direction substantially non-parallel to the rotational axis of the first connection means.

Abstract: A wireless cardiac stimulation device comprising an implantable transmitter module housing a transmitter and a separately implantable battery module housing a battery for powering the transmitter and other device electronics via a subcutaneously routable electrical cable connecting the module is disclosed. The transmitter module contains a transmitter enclosure which comprises one or more ultrasound transducers. Having separate transmitter and battery modules allows implantation of the transmitter module closer to the target receiver implanted in tissue. A discrete battery module also enables easy replacement of the battery without disturbing the transmitter, which is highly desirable.

Abstract: A process and a system for delivering a propellant combination to a rocket engine is described. The process comprises the steps of providing a flow of a hydrocarbon propellant fuel, raising the pressure of the hydrocarbon propellant fuel, cracking the hydrocarbon propellant fuel in a cracker, introducing the cracked hydrocarbon propellant fuel into a combustion chamber of the rocket engine and introducing an oxidizer into the combustion chamber. A system for performing the process is also described.

Abstract: A self-leveling linkage assembly for maintaining a bucket in a level condition and for preventing the bucket from being rolled rearwardly beyond a predetermined maximum rollback position as the lift arm for the bucket is moved to an extreme raised position. The self-leveling linkage assembly includes a control arm rotatably mounted to a tractor frame at a location forwardly of the lift arm pivot, a position link connected between the control arm and bucket, a control valve for actuating a bucket cylinder, and a linkage connected between the control valve and a manually operable control handle. If the bucket rolls back beyond a predetermined position, the position link causes the control arm to rotate which in turn actuates the control valve for the bucket cylinder thereby rolling the bucket to a level position.
