Title: Adaptive load-clamping system
Inventor: JORDAN DEAN CLARK
IPC: B25J13/08
Filed: 1999-09-13
Granted: 2003-06-10
Abstract: A fluid power load-clamping system has a clamp actuated by fluid pressure regulated by at least one fluid valve. The valve may increase a maximum fluid pressure automatically in response to a weight of a load.      A controller causes the valve to permit a relatively high maximum fluid pressure as the clamp closes toward the load to enable high initial clamp closure speed.      Thereafter the valve automatically reduces the maximum pressure as clamping surfaces close into a pre-determined relationship with the load, and then increases the maximum pressure to regulate the gripping force.      Gripping pressure may be regulated continuously while the load is supported by the clamp. A weight measurement system may compensate for a position of the lifting mechanism.

Abstract: A locking assembly for preventing accidental let out of a slack adjuster is provided wherein the slack adjuster includes an elongated hollow housing member and an elongated rod member mounted for reciprocal movement within the hollow housing member. At least a portion of the rod member extends outwardly from a first end of the slack adjuster and is movable in a lateral direction with respect to a longitudinal centerline of the hollow housing member. A rod weldment washer is secured to the rod member at a predetermined location intermediate each end thereof. This rod weldment washer is positioned within the hollow housing member such that a side edge thereof is a predetermined distance from an inner surface of a sidewall of the hollow housing member during normal operation of the slack adjuster. A force applying means is disposed at the first end of the slack adjuster for applying a force to the rod member in a lateral direction with respect to the longitudinal centerline of the rod member thereby causing the rod member and the rod weldment washer to move in a lateral direction with respect to the longitudinal centerline of the hollow housing member to frictionally engage the side edge of the rod weldment washer with the inner surface of the hollow housing member. This frictional engagement prevents longitudinal movement of the rod member within the hollow housing member and consequently prevents the accidental let out of the slack adjuster.

Abstract: A duty cycle management system and method for use in a wireless device having a transmitter which transmits packets in the form of individual packets and/or packet bursts comprising a predetermined maximum number of contiguous packets. The transmitter has an associated predetermined duty cycle limit for transmission of packets and is operable over a duration measurable as a series of time windows each of which comprises a predetermined number of timeslots with each timeslot having a predetermined nominal duration. Transmission of one packet occupies one timeslot. A controller in combination with an instruction set limits the number of packets transmitted during each time period defined by one time window or adjacent time windows, on a sliding basis, so as to limit the duty cycle of transmissions during successive adjacent time windows to the predetermined duty cycle limit. To do so transmission of packets is delayed as needed to establish sufficient idle periods) during the one or adjacent time windows) to maintain the duty cycle within the duty cycle limit. An identification is made prior to the transmission of a packet whether an individual packet or a packet burst transmission mode is to be applied. A counter is used in the preferred embodiment for keeping a running count which correlates to the duty cycle over the period of a time window. The counter is incremented by an amount IC for each timeslot in which a packet is transmitted and is decremented by an amount DC for each idle timeslot, whereby the ratio of IC to DC: is the duty cycle limit. Where a maximum count amount, equal to the predetermined number of timeslots per time window, would be exceeded packet transmission is inhibited.

Abstract: The present invention relates to a method for the treatment of cerebral ischaemia and a drug for the treatment of cerebral ischaemia in particular in humans, as occurs for example in the case of stroke patients.   It was found surprisingly that peripheral administering of erythropoietin to the cerebral tissue affected by the ischaemia has a distinctly protective effect.  Erythropoietin has the effect thereby that the region of the cerebral tissue which is damaged permanently, in particular in the penumbra, is dramatically reduced relative to conventional measures in the case of cerebral ischaemia without erythropoietin administration.
