Abstract: An orthopaedic surgical instrument includes a patella trial and drill guide that may be used to both perform a surgical trial of the patellofemoral joint and guide the surgeon in drilling a number of anchor holes in the patella of the patient.

Abstract: A system and a method for configuring one or more fire extinguishers within a compartment include a configuration control unit configured to determine one or more fluid flow paths within the compartment from a fluid dynamics model. The configuration control unit is further configured to determine a configuration for one or more nozzles of the one or more fire extinguishers based on the one or more fluid paths.

Abstract: A fire extinguishing system includes a storage vessel and a fluidic oscillator. The storage vessel is configured to contain a fire extinguishing agent. The fluidic oscillator is configured to receive the fire extinguishing agent from the storage vessel, and discharge a continuous jet of the fire extinguishing agent while oscillating the jet back and forth through a sweep angle.

Abstract: Examples herein disclose determining whether a computing device should implement a zero watt state according to an engagement of a button. The examples disconnect a power source to the computing device based upon the determination the computing device should implement the zero watt state.

Abstract: Examples disclose a computing system comprising a host device with a connection socket to support multiple types of cables by detecting a first key position and a second key position for determination of the type of cable. Further, the computing system comprises a switching circuit to determine a logic state of each of the key positions. Additionally, the switching circuit is to deliver power associated with the type of cable based on the logic states of the key positions.

Abstract: Systems and methods are provided for aircraft fire extinguishing with heated tubing. One example is a fire extinguishing system that includes a container configured to store a fire extinguishing agent, a tube configured to transport the fire extinguishing agent from the container to a compartment of the aircraft, and a valve configured to initiate a discharge of the fire extinguishing agent from the container and through the tube. The fire extinguishing system also includes a heating element thermally coupled with the tube, and a control member in a cockpit of the aircraft configured to direct the heating element to heat the tube prior to initiating the discharge of the fire extinguishing agent via the valve.

Abstract: A system for protecting the structural integrity of an engine strut may include a first monitor, a second monitor, and a controller communicatively coupled to the first monitor and the second monitor. The first monitor may be mounted proximate an engine strut coupling a turbine engine to an airframe of an aircraft. The second monitor may be mounted proximate the first monitor. The first monitor and the second monitor may each be configured to fail upon reaching a triggering temperature indicative of a burn-through in an engine case during operation of the turbine engine. The controller may be configured to automatically reduce an operating parameter of the turbine engine upon a failure of both the first monitor and the second monitor.

Abstract: Disclosed herein is an example method for expelling a fire suppressant from a container into a distribution manifold. The method includes generating a propellant gas that flows into the container via a first port of the container, thereby causing a pressure within the container to increase. The container includes the fire suppressant prior to the generation of the propellant gas. The method further includes, in response to the pressure within the container exceeding a threshold pressure, expelling the fire suppressant from a second port of the container into the distribution manifold. The generated propellant gas continues to flow into the container via the first port at least until substantially all of the fire suppressant included within the container prior to the generation of the propellant gas is expelled from the container via the second port. Example fire suppression systems are also disclosed herein.

Abstract: One of a first voltage and a second voltage may be selected based on input from a basic input/output system (BIOS). One of the selected voltage and no voltage may be output to a carrier detect (CD) pin and a ring Indicator (RI) pin of a serial communication port, based on the input from the BIOS.

Abstract: Processes for bonding lignocellulosic substrates without an added adhesive are described. The processes of the invention may include exposing the surfaces of the lignocellulosic substrate to a rapid heating source to cause one or more physical, chemical, or other modifications on the surface of the substrate. As a result of the modifications, the surfaces may form a bond with another substrate under elevated temperatures and pressures, for example, produced by a means for pressing such as a conventional hot press used in the woodworking arts. The processes allow a variety of composites such as wood materials for use in the furniture making or construction industries to be manufactured. As the processes forgo the need for petroleum-based adhesives, they are more environmentally sound and occupationally safe than prior art wood product manufacturing methods. Additionally, composite materials made by the processes of the invention are described.

A digital pulse width modulated (PWM) voltage signal may be applied to a gate of a FET switch. The pulse width of the PWM voltage signal may be set to a first value. The pulse width of the digital PWM voltage signal may be digitally incremented to a second value. The digital PWM voltage signal having the pulse width of the second value may be applied to the gate of the FET switch.
