An isoinertial lift machine is described which can be used to evaluate and train patients in the static and dynamic lift modes. The machine consists of an arm which can be positioned on a vertical column. At the end of the arm, various size attachments and handles can be attached. The arm also carries a force sensor that measures the forces applied to the handles. In the static mode, the arm is positioned at a desired height and locked in place. The patient lifts on the handle, and the force sensor registers the lifting force. Since the handle does not move during the lift, the mode is called static. In the dynamic mode, the arm/handle moves in the vertical direction during the lift. A resistance mechanism is used to resist the lifting force applied by the user at the handle. The resisting force is always pulling the arm down, both in the lifting and the lowering motion. The resisting force remains constant throughout the range of motion during lifting. The isoinertial machine can also be used in the static mode. The machine also allows the user to test pushing and pulling loads in static mode only.

A device for measuring linear force which is converted to rotational force or torque. Initially, force is applied in a linear direction to a means for transmitting that force to a rotatable shaft where it is converted to rotational force which can be measured by a strain gauge. The device is mounted on a vertically adjustable column attached to a moveable base.

Devices and techniques for indicating packet processing hints are described herein. A device may receive a data packet. The device may extract a match-action attribute from the data packet that specifies an action to be applied to the data packet. The device may generate a hint field based on the match-action attribute. The hint field may include information to be used for handling the data packet. Other embodiments are also described.

A method of forming bare silicon substrates is described. A bare silicon substrate is measured, wherein measuring is performed by a non-contact capacitance measurement device to obtain a signal at a point on the substrate. The signal or a thickness indicated by the signal is communicated to a controller. An adjusted polishing parameter according to the signal or thickness indicated by the signal is determined. After determining an adjusted polishing parameter, the bare silicon substrate is polished on a polisher using the adjusted polishing parameter.

Method and apparatus to support efficient check-point and role-back operations for flow-controlled queues in network devices. The method and apparatus employ queue descriptors to manage transfer of data from corresponding queues in memory into a switch fabric. In one embodiment, each queue descriptor includes an enqueue pointer identifying a tail cell of a segment of data scheduled to be transferred from the queue, a schedule pointer identifying a head cell of the segment of data, and a commit pointer identifying a most recent cell in the segment of data to be successfully transmitted into the switch fabric. In another embodiment, the queue descriptor further includes a scheduler sequence number; and a committed sequence number that are employed in connection with transfers of data from queues containing multiple segments. The various pointers and sequence numbers are employed to facilitate efficient check-point and roll-back operations relating to unsuccessful transmissions into the switch fabric.

In general, in one aspect, a method is provided for of tracking a network statistic stored within a collection of bits. The method includes storing the collection of bits storing the network statistic as at least a first portion and a second portion. The first portion includes a set of least-significant bits and the second portion includes a set of more significant bits. The method also includes incrementing the first portion based on a packet and determining if the incrementing of the first portion caused a designated bit of the first portion to be set. If it is determined that the incrementing of the first portion caused the designated bit to be set, the method increments the value stored by the second portion and resets the designated bit within the first portion.

In general, in one aspect, the disclosure describes a processor that includes multiple multi-threaded programmable units integrated on a single die. The die also includes circuitry communicatively coupled to the programmable units that reorders and grants lock requests received from the threads based on an order in which the threads requested insertion into a sequence of lock grants.
