  • Publication number: 20200008957
    Abstract: A trial medical instrument for aligning an acetabular component, comprising: a first portion configured to fit within a patient's acetabulum; and a second portion extending from the first portion; wherein the second portion extends from the first portion in a direction that mimics a shape formed by a femoral implant component coupled with an acetabular implant component when a femur to which the femoral implant component is coupled is in a position relative to an acetabulum to which the acetabular implant component is coupled that is near an extent of a typical range of motion of the femur. As used herein, the phrase “extent of a typical range of motion” describes typical angular displacements of a femur as usually limited by patient anatomy.

  • Publication number: 20190339468
    Abstract: Consistent with the present disclosure, one or more spare Widely Tunable Lasers (WTLs) are integrated on a PIC. In the event that a channel, including, for example, a laser, a modulator and a semiconductor optical amplifier in a transmitter or Tx PIC, or a laser, optical hybrid, and photodiodes, for example, in a receiver PIC (Rx PIC), includes one or more defective devices, a spare channel is selected that includes a widely tunable laser (WTL) which may be tuned to the wavelength associated with any of the channels on the PIC. Accordingly, the spare channel replaces the defective channel or the lowest performing channel and outputs modulated optical signals at the wavelength associated with the defective channel. Thus, even though a defective channel may be present, a die consistent with the present disclosure may still output or receive the desired channels because the spare channel replaces the defective channel.

  • Patent number: 10353353
    Abstract: Tools and methods are provided for supplementing an optimization solution for an objective function based on a model of one or more hydrocarbon refining and/or conversion and/or chemical production processes with supporting analysis. The supporting analysis can illustrate for a user how the nature of the feed(s) and/or the selected processing conditions and/or the quality of the product(s) contributes to the optimized solution. A user interface is also provided to facilitate viewing of the information by a user. The supporting analysis can allow a user to understand the factors in the optimized solution that contribute in a significant way.

  • Patent number: 10116411
    Abstract: A method for sending messages through the atmosphere. The method includes sending the messages to an intended recipient, such as an aircraft, on a data link over an operating frequency at or near an atmospheric absorption band, where the operating frequency is selected to be closer to or farther from the absorption band to control the attenuation of the messages in the atmosphere so that the intended recipient is able to receive the messages, but unintended recipients are unable to receive the messages or jamming signals are unable to jam the messages.

  • Patent number: 10073454
    Abstract: A system and method for controlling a swarm of UAVs that are stored on and released from an airborne platform, fly to and destroy a target, where the UAVs download target information from the airborne platform before being released therefrom, do not communicate with each other or the airborne platform while in flight, and do not depend of the presence of GPS. Each UAV includes a vision sensor that provides image data, a navigation module that receives the image data and causes the UAV to navigate and fly towards the target, and a target destruction module that receives the image data and causes the UAV to destroy the target.

  • Patent number: 10018569
    Abstract: A method for detecting defects in a composite structure, such as in an aircraft structure, that includes sending an optical signal down an optical fiber embedded in the composite structure and analyzing the optical signal at a detector. If it is determined that the optical signal is turning on and off or an increase in the bit error rate is occurring at the detector, the composite structure may be delaminating or the composite structure may be somehow damaged. If it is determined that the composite structure is damaged, the optical signal can be sent down a different optical fiber that may not be at a location where the composite structure is damaged, and a continuous beam of light can be sent down the optical fiber that is at the damaged part of the composite structure to determine whether the damage is increasing.

  • Publication number: 20170254622
    Abstract: A manned aircraft and unmanned aerial vehicles (UAVs) fly on a mission as a team. The UAVs carry additional weapons and/or munitions that can be controlled by the manned aircraft. The pilot of the manned aircraft selects weapons or munitions carried by either the manned aircraft or one of the UAVs. A display in the manned aircraft illustrates weapons available on both the manned aircraft and UAVs. The pilot of the manned aircraft picks a weapon from the display and then targets and fires the weapon. The targeting and guidance of the weapon can be carried out using computers on the manned aircraft and/or computers on the UAV.
