Abstract: A detonator includes a substrate, a controller mounted to the substrate, and a sensor coupled to the controller to measure a temperature, pressure, acceleration or other environmental info and/or electrical status of the internal electronics of the detonator. The controller is configured to store the measured environmental parameter and/or electrical status in a memory of the detonator, transmit the stored data from the detonator to a remote master controller, execute an action in response to a value of the measured environmental parameter, and/or prevent or modify at least one detonator function in response to the data obtained.

Abstract: A device for spinal surgery that may be used for tightening a locking cap onto at least a portion of a pedicle screw. The device may include a torque-generating body having a proximal end and an opposing distal end and a drive shaft rotatably driven by the torque-generating body. A proximal end of the drive shaft may be operatively engaged to the distal end of the torque-generating body and an opposing distal end of the drive shaft may engage at least a portion of one of the locking cap and the pedicle screw. An anti-torque device is provided that has an elongated and generally hollow member defining a longitudinal axis. The member has a proximal end and an opposing distal end, where the proximal end of the anti-torque device may be fixed from rotating relative to at least a portion of the torque-generating body and the distal end may be fixed from rotating relative to a spine rod or a pedicle screw.

Abstract: Apparatus and methods for controlling unmanned systems (UMSs), such as unmanned aircraft, are provided. A UMS can include core systems, auxiliary systems, a payload, a physical computer, a network, and a power system. The network can enable the physical computer to communicate with the auxiliary systems using a second communications tier and with the payload using a third communications tier. The network and the physical computer can logically separate the second and third communications tiers. The power system can provide a first, second, and third power domains respectively for the core systems, the auxiliary systems, and for the payload. The power system can include circuitry that inhibits an overcurrent fault in the third power domain from causing an electrical fault in the first and second power domains and that inhibits an overcurrent fault in the second power domain from causing an electrical fault in the first power domain.

Abstract: Apparatus and methods for controlling unmanned systems (UMSs), such as unmanned aircraft, are provided. A UMS can be provided that includes a network, auxiliary systems, and a payload, where the network can connect the auxiliary systems and the payload. A network switch of the network can logically separate the network into at least a second tier of communications and a third tier of communications. The network can be used to control the UMS by at least: controlling the auxiliary systems using messages communicated by the second tier of communications, and communicating with the payload using messages communicated by the third tier of communications.

Abstract: Apparatus and methods for controlling unmanned systems (UMSs), such as unmanned aircraft, are provided. A UMS can be provided that includes core systems, auxiliary systems, a payload, and a power system. The power system can provide uninterruptible power for a first power domain that includes the core systems. The power system can provide interruptible power for each of a second power domain and a third power domain. The second power domain can include the auxiliary systems, and the third power domain can include the payload. First circuitry of the power system can prevent a single overcurrent fault in the third power domain from causing an electrical fault in either the first power domain or the second power domain. Second circuitry of the power system can prevent a single overcurrent fault in the second power domain from causing an electrical fault in the first power domain.

Abstract: An implant may include a housing and a blade having a retracted position in the housing and an extended position where the blade extends outwardly from the housing. The implant also includes a blade actuating component, the blade actuating component comprising a driven shaft portion. The blade actuating component is configured to move the blade between the retracted position and the extended position. The housing may include a chamber portion receiving a portion of the driven shaft portion of the blade actuating component. The driven shaft portion may include an opening and a blocking pin received within the opening. In a first position, the blocking pin limits insertion of the blade actuating component. In a second position, the blade actuating component is unrestricted by the blocking pin.

Abstract: A cage for implanting in bone includes a main body having a fastener mounting receiver. The main body includes a first surface that contacts a first bone surface, a second surface that contacts a second bone surface, a side wall extending between the first and second surfaces, and a front wall comprising a connection surface, wherein the fastener mounting receiver extends from the connection surface. A fastener is placed within the fastener mounting received and configured to engage and fix a plating device on the connection surface of the main body.
