| 20110208323 | METATARSAL JOINT SHAPE FOR PROSTHETIC FOOT AND CONTROL MECHANISM AND SYSTEM FOR SAME - A prosthetic foot can include a plate-like foot member extending along a longitudinal axis between an anterior end generally corresponding to a toe portion of a foot to a posterior end, and a metatarsal hinge comprising an elongate groove extending between medial and lateral edges of the foot member. The elongate groove can intersect the longitudinal axis of the foot member, and can be positioned along the length of the foot member at a location generally corresponding to a metatarsal region of the foot. The metatarsal hinge can also comprise a plurality of elongate apertures that extend completely through the foot member, or a plurality of recessed channels that extend only partially through the foot member, or a combination thereof. | 08-25-2011 |

| 20100004757 | SMOOTH ROLLOVER INSOLE FOR PROSTHETIC FOOT - A prosthetic foot includes a foot member, a heel member operatively coupled to the foot member. At least one of the heel member and foot member define an arch portion that faces a support surface that the prosthetic foot contacts during use. An insole member contacts said arch portion, the insole member configured to facilitate a rollover of the prosthetic foot in at least one of a lateral-medial and a medial-lateral direction during ambulation. | 01-07-2010 |

| 20100152865 | NOISE REDUCTION DEVICE FOR ARTICULATING JOINT, AND A LIMB SUPPORT DEVICE HAVING THE SAME - An articulating connection or joint for a limb support device having a first support member and a second support member pivotably couples together the first support member and the second support member. The articulating connection can include one or more first articulating connection member, or load-bearing pin, and one or more second articulating connection member, or bushing, disposed about the first and second support members. The load-bearing pin is coupled to one of the support members and the bushing is coupled to another of the support members. The bushing is configured to rotatingly receive the load-bearing pin and interacts with an actuation member configured to apply a force on the load-bearing pin to eccentrically align the load-bearing pin relative to the bushing so that the load-bearing pin continuously follows and contacts a bearing surface of the bushing during use of the limb support device, thereby inhibiting noise generation from the interaction of the bushing and load-bearing pin. | 06-17-2010 |

| 20090293641 | METHOD OF MEASURING THE PERFORMANCE OF A PROSTHETIC FOOT - A method of measuring the performance of a prosthetic foot includes obtaining a pressure distribution of the prosthetic foot during a motion of the prosthetic foot and determining whether the pressure distribution falls within a preselected range of performance values for the prosthetic foot. The pressure distribution comprises a trajectory illustrating the progression of a center of pressure of the prosthetic foot during motion. A prosthetic foot can also be designed to approximate a pressure distribution corresponding to a preselected range of performance values. | 12-03-2009 |
| 20100286796 | CONTROL SYSTEMS AND METHODS FOR PROSTHETIC OR ORTHOTIC DEVICES - Geomagnetic methods and systems are used for monitoring the directionality of a prosthetic or orthotic device. Certain methods may include measuring multiple data points over a particular time interval to identify orientation information with respect to a prosthetic or orthotic device and/or used in the real-time control of the prosthetic or orthotic device. In certain examples, multiple points may be further compared with stored orientation data associated with predefined unsafe gait patterns. Control instructions and/or alerts based on the geomagnetic measurements can then be generated for the prosthetic or orthotic device, such as if the orientation data information matches one of the predefined unsafe gait patterns. | 11-11-2010 |
| 20100324698 | FEEDBACK CONTROL SYSTEMS AND METHODS FOR PROSTHETIC OR ORTHOTIC DEVICES - Methods and systems are used for monitoring a global position or location of a prosthetic or orthotic device and to provide feedback control of the device. Certain methods may employ remote transmitting devices and receivers to recognize when a prosthetic or orthotic device user is in a moving vehicle and, therefore, initiate automatic shut-off, driving mode, or relaxed mode. Other methods may employ remote transmitting devices and receivers to identify the global position of the prosthetic or orthotic device, compare the global position to a stored terrain mapped database and output feedback control instructions and/or alerts to the prosthetic or orthotic device based at least in part on the stored terrain mapping information. | 12-23-2010 |
| 20110098606 | SENSING SYSTEMS AND METHODS FOR MONITORING GAIT DYNAMICS - Systems and method for monitoring gait dynamics are disclosed. The performance of an orthotic or prosthetic device or other device associated with a limb may be measured based on the resistance of a bending sensor. Data from the sensors is gathered or processed, particularly for purposes of alignment, safety, failure, usage, selection, and artificial proprioception. Information relating to the device may be outputted visually or auditorily to an individual. | 04-28-2011 |
| 20110106274 | SYSTEM AND METHOD FOR MOTION-CONTROLLED FOOT UNIT - A system and method associated with the movement of a limb. In one example, the system, such as a prosthetic or orthotic system, includes an actuator that actively controls, or adjusts, the angle between a foot unit and a lower limb member. A processing module may control movement of the actuator based on data obtained from a sensor module. For instance, sensing module data may include information relating to the gait of a user and may be used to adjust the foot unit to substantially mimic the movement of a natural, healthy ankle. The system may further accommodate, for example, level ground walking, traveling up/down stairs, traveling up/down sloped surfaces, and various other user movements. In addition, the processing module may receive user input or display output signals through an external interface. For example, the processing module may receive a heel height input from the user. | 05-05-2011 |

| 20100324456 | SYSTEMS AND METHODS FOR PROCESSING LIMB MOTION - Control systems and methods are disclosed for processing a time series of signals associated with the movement of a device associated with a limb. The time series of motion signals is filtered, such as thorough an autoregressive filter, and compared to stored data sets representing a limb-motion event and/or phase. In certain examples, a plurality of accelerometers generate the time series of motion signals based at least on acceleration measurements in three orthogonal directions and/or planes. The acceleration measurements may relate to the movement of an artificial limb, such as a prosthetic or orthotic device. Upon determining an event and/or phase of limb motion, the control system may trigger an actuator to appropriately adjust one or more prosthetic or orthotic joints. | 12-23-2010 |

| 20090222105 | TRANSFEMORAL PROSTHETIC SYSTEMS AND METHODS FOR OPERATING THE SAME - Certain embodiments of the invention relate to increasing the functionality of a transfemoral prosthetic device. In one embodiment, the transfemoral prosthetic device is configured such that the prosthetic knee maintains a load consistent with a healthy knee walking on level ground, while the prosthetic ankle adjusts for the incline or decline. In certain embodiments, adjustments, such as a toe lift function, are automatically performed after about three strides of the transfemoral prosthetic device user and/or when each of the strides has a stride speed of at least about 0.55 meters/second. | 09-03-2009 |
