Abstract: Technology is described to provide a foot/ankle prosthesis for individuals with transfemoral limb loss. This technology is able to store and release energy and thus individuals or patients who are using the foot/ankle prosthesis are able to expend less energy when walking or running. The device or system can include a prosthetic foot/ankle system with a linear or rotary hydraulic damper such that the hydraulic damper is attached to dynamic energy storing spring elements. The axis of rotation of the system can be near to that of an intact human ankle. The system can utilize spring elements based on the vertical displacement of the center of pressure of an intact normal foot. The system can also provide user adjustable heel height.

Abstract: Technology is described to provide a locking device to control movement of a prosthetic limb. The technology may include a hydraulic damper having a movable damper wall in a hydraulic housing of the hydraulic damper, and the movable damper wall may form a first chamber and second chamber in the hydraulic damper. A first fluid channel may be coupled to the first chamber. In addition, a latch may be in fluid communication with the first fluid channel. A poppet valve can be configured to set the latch in an open position when pressure is reduced in the first chamber and to stop fluid movement when pressure is increased in the first chamber. A second fluid channel between the second chamber and the latch may enable fluid to flow between the second chamber and the latch.

Abstract: Technology is described to provide a foot and ankle prosthesis for individuals with lower limb loss. This technology is able to store and release energy and individuals or patients who are using the foot/ankle prosthesis may be able to expend less energy when walking. The system includes a hydraulic damper attached to dynamic energy storing spring elements. The axis of rotation of the system can be near to that of an intact human ankle, providing biomimetic function. The system can utilize spring elements based on the vertical displacement of the center of pressure of an intact normal foot. A hydraulic system can provide user adjustable heel height and adaptation to inclines. The dorsiflexion and plantar flexion resistances can be independently adjusted manually or electrically. In addition, the system can be automatically locked in dorsiflexion when loaded and unlock when unloaded.

Abstract: A mechanism is provided in a data processing system to implement a medical concept searching engine for improving searches of medical concepts based on an index model. The mechanism generates a concept index model data structure that records medical concepts and corresponding numbers of instances of the medical concepts in the corpus of documents. Responsive to receiving a search request from a user, the medical concept searching engine identifies at least one medical concept in the search request and one or more related medical concepts that are related to the at least one medical concept based on an ontology data structure. The medical concept searching engine generates a bubble graph user interface comprising a plurality of bubbles corresponding to the at least one medical concept and the one or more related medical concepts.

Abstract: Technology is described which can provide a quick disconnect and overload protection mechanism for a prosthetic limb that is used with an osseointegrated percutaneous post. The technology can provide a way to easily don and doff a prosthetic limb. This quick disconnect may also provide a resettable torsional overload protection mechanism and/or a fusible link that may act to protect the osseointegrated percutaneous post from both axial and bending over-loads.

Abstract: Technology is described for easy and safe attachment of a prosthetic limb to a percutaneous post that has been osseointegrated into the remnant limb of an individual with limb loss. A quick-disconnect device for a prosthetic limb can comprise a percutaneous post support assembly comprising a post locking assembly attached to a percutaneous post. A roller support can be coupled to the percutaneous post support assembly and can support torsional breakaway rollers. A release housing assembly can be coupled to the percutaneous post support assembly, and can comprise a limb support housing supporting a limb attachment structure to support a prosthetic limb. The release housing assembly comprises a torsional breakaway spring. The plurality of torsional breakaway rollers are each biased to the torsional breakaway spring to generate a spring force to restrict or limit rotation of the percutaneous post support assembly. Other breakaway springs and rollers are provided for bending release and axial release.

Abstract: An automated concept-based autosuggest mechanism is provided for automatically tailoring autosuggestions in a search engine to particular medical concepts being searched. The mechanism identifies a concept-based text pattern dictionary data structure associated with text being dynamically entered by a user based on a previously identified item. The mechanism dynamically matches a set of text patterns in the concept-based text pattern dictionary data structure with a portion of text being dynamically entered by the user into a field of the user interface. The mechanism generates a user selectable output in the user interface specifying the matching set of text patterns from the concept-based text pattern dictionary data structure. The mechanism automatically populates the field of the user interface with a selected text pattern from the set of matching text patterns in response to user selection of the selectable text patter in the user selectable output in the user interface.

Abstract: Systems and methods for providing targeted content to a patient who has received a prescription for medication. The systems and methods generally provide the content prior to the Point of Sale (POS) of the actual prescription allow patients to review the content and possibly act on it prior to actually obtaining the medication. Depending on embodiment, the content may be provided by a pharmacy at or around the time of dispensing or by a physician at or around the time of prescribing.

Abstract: Techniques are described for load balancing between DHCP servers at a DHCP client. Embodiments include receiving, at the DHCP client, a respective DHCPOFFER message from each of two or more DHCP servers, wherein each of the DHCPOFFER messages includes an IP address offer and load information describing a current workload of the respective DHCP server. One of DHCP servers is selected, at the DHCP client, to accept an offer for an IP address from, based on the received load information and a subnet on which the selected DHCP server is located. Embodiments transmit a DHCPREQUEST message, from the DHCP client, to the selected DHCP server, to accept the IP address offer from the selected DHCP server.

Abstract: Techniques are described for detecting duplicate IP addresses at a DHCP relay agent. Embodiments identify a list of DHCP clients that have valid IP address leases from one or more DHCP servers. Additionally, network traffic from a first node passing through the DHCP relay agent is monitored. Embodiments then determine whether the first node is using a duplicate IP address, based on the monitored network traffic and the identified list of DHCP clients.

Abstract: Systems and methods to analyze layer-2 data frame switch forwarding are provided. A first switch may be coupled to a second switch. The first switch may maintain state information mirroring the state of the second switch. A sequence number may be appended to a data frame that is received at the first switch. Forwarding compliance of the second switch may be determined by analyzing a runtime attribute of the first switch.
