  • Publication number: 20250057658
    Abstract: The present disclosure includes examples of an implant system configured for targeted joint resurfacing in which only an area including the osteochondral defect is resected, wherein the area resected occupies an area smaller than an entire joint surface. The implant system can include a monolithic first implant with 3D printed metal and a second implant including a plastic portion overmolded onto a metal portion. The metal portion of the second implant also includes 3D printed metal. The first and/or second implants include solid metal portion(s) and porous metal portion(s). In an example, the first implant can be a femoral implant and the second implant can be a tibial implant. The first and second implants can be used on their own or in tandem.

  • Publication number: 20240351592
    Abstract: Performance of a substitute upstream processing component is tested, in order to determine whether that performance is sufficient to support a downstream processing component, within an autonomous driving system, in place of an existing upstream processing component. The existing upstream processing component and the substitute upstream processing component are mutually interchangeable in so far as they provide the same form of outputs interpretable by the downstream processing component, such that either upstream processing component may be used without modification to the downstream processing component. A direct or indirect metric-based comparison is formulated in terms of the resulting performance of the downstream processing component.

  • Publication number: 20220297707
    Abstract: Herein, a “perception statistical performance model” (PSPM) for modelling a perception slice of a runtime stack for an autonomous vehicle or other robotic system may be used e.g. for safety/performance testing. A PSPM is configured to: receive a computed perception ground truth; determine from the perception ground truth, based on a set of learned parameters, a probabilistic perception uncertainty distribution, the parameters learned from a set of actual perception outputs generated using the perception slice to be modelled. The PSPM comprises a time-dependent model such that the perception output sampled at the current time instant depends on at least one of: an earlier one of the perception outputs sampled at a previous time instant, and an earlier one of the perception ground truths computed for a previous time instant.

  • Publication number: 20220297709
    Abstract: Herein, a “perception statistical performance model” (PSPM) for modeling a perception slice of a runtime stack for an autonomous vehicle or other robotic system may be used e.g. for safety/performance testing. A PSPM is configured to: receive a computed perception ground truth t; determine from the perception ground truth t, based on a set of learned parameters, a probabilistic perception uncertainty distribution of the form p(e|t), p(e|t,c), in which p(e|t,c) denotes the probability of the perception slice computing a particular perception output e given the computed perception ground truth t and the one or more confounders c, and the probabilistic perception uncertainty distribution is defined over a range of possible perception outputs, the parameters learned from a set of actual perception outputs generated using the perception slice to be modeled, wherein each confounder is a variable of the PSPM whose value characterized a physical condition on which p(e|t,c) depends.

  • Publication number: 20130164828
    Abstract: An integrated fibre based device for transfecting material into a cell comprising an optical fiber that has a lens formed at its end for directing light to a surface of the cell, and a channel for delivery of the material for transfection into the cell.

  • Publication number: 20050147433
    Abstract: A variable torque device for maintaining constant tension in a web of material as the web is unwound from a supply roll. The variable torque device includes a lead screw attached to the shaft of the supply roll via an appropriate gear ratio. A coil spring is located between a hub on the lead screw and a set of rings and friction pads. As the lead screw rotates, the hub translates, thus changing the displacement of the coil spring, which in turn changes the loading of the rings and friction pads. With a full supply roll the coil spring is compressed so as to create an amount of torque to create the desired web tension. As the supply roll unwinds, the rotation of the lead screw translates the hub to expand the coil spring, reducing the torque and maintaining the web tension constant.

  • Patent number: 6106320
    Abstract: An electrical receptacle includes a receptacle housing, a movable element, an interlock mechanism, a release mechanism, and a blocking element. The receptacle housing has a receptacle opening having a longitudinal axis. The movable element is located within the receptacle opening and is designed to move along the longitudinal axis between an extended position and an inserted position. The interlock mechanism is connected to interlock with the movable element when the movable element is in the inserted position. The interlock mechanism also maintains the movable element in the inserted position. The release mechanism is coupled to the interlock mechanism, accessible from outside the receptacle housing, and operable to disengage the interlock mechanism from the movable element to permit the movable element to move to the extended position.
