Abstract: A removable wedge for high tibial osteotomy surgery, comprising: a truncated wedge configured to provide a patient specific correction to the weight bearing axis based on 3D data for that patient’s tibia, femur and/or fibula; and an anterior flange configured to locate the partial wedge in a predetermined location on the tibia of that patient. Also a method for pre-operative planning, a method of designing a wedge, a method of printing a wedge a reusable wedge and a prosthetic implant.

Abstract: A support plate, for supporting the two parts of a tibia after a tibial osteotomy, is generally in the shape of a T with a stem having top and bottom ends and a cross piece extending across the top end of the stem. The support plate has a rear surface arranged to contact the tibia. The rear surface of the stem is convex in its central longitudinal plane over a first region of the plate, and the rear surface of the cross piece is concave in its transverse plane.

Abstract: A femoral component (101) for a knee prosthesis, the femoral component (101) comprising: a body portion (103) having: a lateral portion (109) and a medial portion (111) when in an implanted configuration, wherein a parasagittal plane is located at the intersection between the lateral portion (109) and the medial portion (111); and a patella track (105) extending anterior-posteriorly around the body portion (103), wherein the patella track (105) comprises a first patella track portion (105a) that is directed laterally away from the parasagittal plane as it extends towards a posterior end of the patella track (105).

Abstract: Disclosed are various embodiments for computer-aided tracking and motion analysis with ultrasound. A computing device is employed to access an ultrasound video generated by at least one ultrasonic imaging device and/or at least one motion sensing camera. A target patch embodied is tracked throughout frames of the ultrasound video by compressing target patches of individual ones of the frames of the ultrasound video into vectors; generating a space partitioning data structure for each of the frames of the ultrasound video; and identifying an image intensity feature for each frame utilizing a corresponding one of the space partitioning data structures generated for each frame of the ultrasound video. Optimized tracking locations may be determined for a sequence of the ultrasound video using the image intensity feature identified for each frame.

Abstract: A communication is received from a fare media which includes a token associated with a transit account and a risk score based on a usage history of the account which is indicative of a likelihood of default associated with the account. One or more positive or negative lists are received from a server. Positive lists include first account identifiers associated with accounts in good standing. Negative lists include account identifiers associated with accounts in poor standing. A determination whether the token is associated with an account represented by one of the first or one of the second account identifiers is made. A determination, based on the risk score or the determination of the association of the token is made whether to grant access to the transit system. Information related to the determination of whether to grant access is communicated to the server. Access is granted to the transit system.

Abstract: Among other things, an augmented reality device that is configured and/or arranged to present particular device operational health information as a function of the distance between the augmented reality device and the particular device.

Abstract: Systems and techniques are presented for processing a user through a paid entry gate using a mobile device. The mobile device receives a beacon packet from a first wireless beacon and wakes up an application. The application wakes up by transitioning to an active or background execution state. The application transmits validation data to a computer server system and the computer server system validates an account of the user. The mobile device receives a beacon packet including a gate identifier that is a unique identification of the paid entry gate from a second wireless beacon and transmits the gate identifier to the computer server system. The computer server system receives the gate identifier, debits the account of the user, and transmits a signal to a gate entry device associated with the gate identifier to grant the user passage through the paid entry gate.

Abstract: A handheld transit fare device is provided. The transit fare device includes an NFC interface configured to send and receive data, a memory, and a processor. The processor is configured to receive, via the interface, a list of transactions from a host device using standard smart card protocol commands and reply structures. The list of transactions includes identifiers of fare access media used to gain access to a transit vehicle. The processor is configured to store the list of transactions on the memory and to provide a first indication that the list of transactions has been received. The processor is configured to receive, via the interface, an identifier from a fare access media on the transit vehicle, determine whether the identifier from the fare access media matches one of the identifiers from the list of transactions, and provide a second indication that provides a result of the determination.
