Abstract: Soluble and stable liquid compositions containing a plant growth regulator selected from the group consisting of cytokinin and a gibberellin, an acid solubilizer such as citric acid, tartaric acid or glycolic acid and a solvent; as well as methods for making and using the composition are disclosed. The compositions improve solubility, handling, stability, safety, as well as activity improvements such as improved plant growth, yield, fruit thinning or sizing and quality. The compositions are soluble and stable by adding an ethoxylated alkyl alcohol wherein the growth regulator is 6-benzyladenine (6-BA) or forchlorfenuron (CPPU) and the ethoxylated alcohol surfactant is C12-15 alkyl alcohol in propylene glycol. The compositions may also contain a cytokinin such as 6-benzyladenine (6-BA) or forchlorfenuron (CPPU) that is increased in solubility and activity and by synergistically combined with GA3 or GA4A7 as well as in storage stability by adding an antioxidant.

Abstract: A system and method for detecting and predicting neurological events with an implantable device uses a relatively low-power central processing unit in connection with signal processing circuitry to identify features (including half waves) and calculate window-based characteristics (including line lengths and areas under the curve of the waveform) in an electrographic signal received from a patient's brain. The features and window-based characteristics are combinable in various ways according to the invention to detect and predict neurological events in real time, enabling responsive action by the implantable device.

Abstract: The invention relates to a debarking machine for the debarking of logs and for the expulsion of at least some of the removed bark from a wood flow passing through the debarking machine. The debarking machine having a number of rotating debarking shafts extending parallel to an advancing direction (A) of the logs to be fed therethrough. The debarking shafts are provided with a number of teeth adapted to strip bark off the logs transversely to the lengthwise direction of the logs and at the same time to convey the logs transversely relative to said shafts. The shafts, together with the teeth thereof constitute at least a section of a support surface upon which the logs travel through the debarking machine. For feeding the logs into the debarking machine, its admission end is provided with a conveyor adapted to positively feed the logs through an opening in the admission end of the debarking machine. The feed rate and feed force of the conveyor are preferably regulated.

Abstract: The invention relates to a debarking shaft arrangement for a debarking machine (1). A number of rotatable debarking shafts (3) extending parallel to the advancing direction of the logs (2) are provided with a number of teeth (4) extending beyond the circumferential surface of the shaft (3) and adapted to strip bark off the logs transversely to the lengthwise direction of the logs. The teeth (4) are designed to be effective in both rotating directions of said rotatable debarking shafts (3), and the debarking shafts (3) are designed to be reversibly mounted in the debarking machine. Reversible debarking shafts equipped with bi-directionally effective teeth permit renewal of worn teeth on a debarking shaft by reversing the orientation of the shaft relative to the debarking machine.

Abstract: An implantable neurostimulator adapted to provide adaptive electrical brain stimulation includes a detection subsystem for isolating an electrographic signal characteristic and a stimulation system for applying an adaptive stimulation signal based at least in part upon the electrographic signal characteristic and correlated with the electrographic signal. Undesired learning of and acclimation to stimulation characteristics are avoided and stimulation efficacy is improved by adapting or otherwise varying the adaptive stimulation signal in relation to the electrographic signal.

Abstract: An implantable cardiac pacemaker having a housing containing pacing circuitry, a signal generator, and an electromagnetic transducer. The transducer has an electrical input line connected to the signal generator, and an electrical output line connected to the pacing circuitry. Consequently, a forcing motion on the transducer sends an electrical signal to the pacing circuitry, and operation of the signal generator causes the transducer to vibrate. The pacemaker may also include a disablement switch connected to the signal generator, with the signal generator operating in response to activation of the switch to cause the transducer to generate an audible warning tone while the pacemaker is disabled.
