摘要:
A foot pad device and a method of obtaining weight data from a force sensor in a foot pad worn by a user engaging in a footstep, including placing the force sensor under the ball of the foot of the user and/or the heel of the foot of the user; receiving an entered patient weight value for the user; collecting force data from the force sensor; calculating a weight value based on the collected force data and a scaling and/or offset parameter; comparing the calculated weight value to the entered patient weight value; comparing the calculated weight value to zero; adjusting the scaling and/or offset parameter; and repeating the steps periodically. The method may include comparing the collected force data to a functionality indication range, flagging the force sensor if the collected force data is outside the functionality indication range, and disregarding force data from the flagged force sensor.

摘要:
An actuator system for extending and flexing a joint, including a multi-motor assembly for providing a rotational output, a rotary-to-linear mechanism for converting the rotational output from the multi-motor assembly into an extension and flexion of the joint, and a controller for operating the actuator system in several operational modes. The multi-motor assembly preferably combines power from two different sources, such that the multi-motor assembly can supply larger forces at slower speeds (“Low Gear”) and smaller forces at higher speeds (“High Gear”). The actuator has been specifically designed for extending and flexing a joint (such as an ankle, a knee, an elbow, or a shoulder) of a human. The actuator system may, however, be used to move any suitable object through any suitable movement (linear, rotational, or otherwise).

The invention relates to embodiments of methods for extending a subject-controllable range of joint motion, and for increasing subject control of joint movement within a range of motion. Embodiments include fastening a powered device around a joint so as to be able to control the joint, allowing the subject to move the joint within a range of volitional motion, and then engaging the powered device to support movement of the joint into an expanded, rehabilitative range. In some embodiments, the device supports joint movement by substantially providing the force to move the joint beyond the volitional boundary. In other embodiments, supporting movement includes the subject substantially providing the force, and the device allowing movement only in a desired direction. The invention further relates to a system for increasing the functional capability of a joint by implementing embodiments of the method. By such methods and system, rehabilitation is accomplished both by building strength, and training neural pathways.

摘要:
A system for issuing a family of instructions during a single clock includes a decoder for decoding the family of instructions and logic, responsive to the decode result, for determining whether resource conflicts would occur if the family were issued during one clock. If no resource conflicts occur, an execution unit executes the family regardless of whether dependencies among the instructions in the family exist.
摘要:
A mechanism for handling exceptions in a processor system that issues a family of more than one instruction during a single clock that utilizes the exception handling procedures developed for single instructions. The mechanism detects an exception associated with one of the instructions in the family, inhibits the data writes for the instructions in the family, flushes the pipeline, and reissues the instruction singly. The exception handling procedure for the single instruction may then be utilized.

In a data processing system, a multiplication operation is immediately followed by a redundant multiplication operation, using the same, albeit altered, operands, to check the initial result. The initial result is immediately available for use, but the check is not performed until some time later. The original operands are altered for the redundant multiplication operation by shifting one operand 1 bit, and swapping them before multiplication.
摘要:
A branch recovery mechanism completes the processing of a concurrently issued family of instructions depending on the location of the branch instruction in the family and on whether the branch was correctly predicted. If the branch was not correctly predicted, the writes and stores of instructions in the family the precede the branch instruction are completed and those instructions are retired. However, the writes and stores of the instructions in the family following the branch instruction are inhibited.
摘要:
A system and method for controlling network traffic flow in a multi-processor network is disclosed. The method employs a two-part algorithm to determine when it is appropriate for a client node to transmit data over a network to one or more server nodes. The first part of the algorithm calls for the client node to transmit data over the network after receiving an acknowledgement from one or more of the server nodes to which data transfer is outstanding. The second part of the algorithm provides for the client node transmitting data over the network after a predetermined time interval has elapsed since a data transmission. The time interval is based, in part, on the length of outstanding data packets and a statistical analysis of the number of nodes transmitting or receiving data packets. The transmission of data over the network is accomplished by a hybrid scheme, comprising a combination of PUSH and PULL transmission protocols.
