An improved method of reducing and stabilizing the sternum after a sternotomy includes fixing a staple at the anterior surface of the sternum adjacent to each outlet for trans-sternal wire sutures. The staples are applied to the sternal halves to reinforce the bone adjacent to the suture outlets so as to prevent the suture from cutting into the bone. As each suture loop is tightened to adapt the sternum, the suture loop abuts the staples adjacent the suture outlets. The staples are deformed under force applied by the suture loop to indicate that the loop has been tightened to an optimum degree. A sterile surgical staple gun is employed to install the staples in the sternal halves. A kit for performing the improved sternal reduction procedure includes a pre-sterilized staple gun loaded with surgical staples, as well as suture / needle assemblies.

A system drives one or plurality of LEDs regulating their brightness by controlling LEDs average current or voltage. The system includes a switching power converter and an integrated digital regulator with at least one of electrical, thermal and optical feedbacks. The regulator is constructed as a hysteretic peak current mode controller for continuous mode of operation of the power converter. For discontinuous mode of operation of the power converter a pulse averaging sliding mode control is being used. Average LED current is measured by integrating LED pulse current at off time and hysteretically adjusting on time of the power switch. Input battery is protected from discharging at abnormally low impedance of the output.

A plasma generation method is provided to generate and maintain plasma by supplying a predetermined power that is lower than a normal power to a plasma generator. Plasma of an ignition gas is generated by supplying the normal power to the plasma generator. A power input to the plasma generator is decreased by a first power that is smaller than a difference between the normal power and the predetermined power. The power input to the plasma generator is decreased by a second power that is smaller than the first power. Decreasing the power input to the plasma generator by the second power is performed after decreasing the power input to the plasma generator by the first power and is repeated a plurality of times.

Smart Active Tyre Pressure Optimising System [TPOS]102 is a highly time sensitive design and technique that acts instantaneously in sensing and controlling the tire pressure particularly in imminent and inevitable critical driving situations to reduce emergency & high speed breaking distance, mitigate—loss of traction, hydroplaning, roll over, loss of stability, over & under steering, break failure, loss of control due to puncture by smartly sensing, perform context aware computing and directing the Tyre Pressure Control Units [TPCU]104 to instantaneously control the tyre pressure in right time with right pressure on right tyres thereby actively controlling the footprint and sidewall deformation rate to enhance traction & stability simultaneously sustaining drivability or steerability ultimately to avoid or reduce the impact of collusion and overcome or mitigate critical situations for protecting the vehicles, occupants, pedestrians and other objects around or on the way; also according to design, configurations and scenarios the system instantaneously optimises the tyre pressure on all tyres for further safe driving till next restoration else restores the pressure to optimum preset value utilising inbuilt reservoir or other external restoration systems immediately after the vehicle overcomes the critical situation to continue with safe and comfortable driving. In critical situations TPOS performs sensing, pre computing, current computing for controlling the tire pressure during critical situation, post computing to optimise tire pressure after overcoming accordingly. TPOS 102 utilise smart and adaptive closed loop processing algorithm with predetermined and tested lookup table to instantaneously check and compare the effects between predetermined and tested real world scenarios to the actual real world scenarios for actively sensing, computing and controlling the tire pressure accordingly to mitigate the critical situations. The controlling of tyre pressure is computed mainly based on parameters comprising of sensor system, vehicle safety and stability systems, nature of breaking & break force distribution, tires upper & lower cut-off pressure values, sensing reservoirs and tires internal & external pressure, temperature, moisture, humidity, wheel & tire specifications, vehicle & wheel speed, acceleration & deceleration, vehicle orientation & axial rotation, transverse motion & lateral acceleration, tires position or angle of attack, load & torque distribution, tire traction, steering position, cornering effects, change in Centre of gravity, over & under steering, hydroplaning, sensing road conditions, etc and to further enhance the efficiency, the system interoperates with vehicles existing safety and stability systems like ABS, EBD, ESC, TCS, Rollover mitigation systems, ECU, BA, Precrash systems, suspension & vertical dynamics, radar assisted auto breaking, cruise control system, aerodynamics & airbrakes etc. Other aspects of present invention are controlling the tire temperature according to environmental temperature, moisture and humidity thereby to enhance traction and vary tire pressure according to change in centre of gravity & load, driving modes—comfort, standard and sports modes.

The occurrence of a slippage of a robot in operation, following a desired gait, is determined, and the permissible range of a restriction object amount, such as a floor reaction force horizontal component or a floor reaction force moment vertical component to be applied to the robot, is variably set according to a slippage determination result. A provisional motion of a desired gait is determined using a dynamic model, and if the restriction object amount defined by the provisional motion deviates from the permissible range, then the motion of a desired gait is determined by correcting the provisional motion by changing the changing rate of the angular momentum of the robot from the provisional motion so as to limit the restriction object amount to the permissible range, while satisfying a dynamic balance condition.

The invention provides a control algorithm of multi-unmanned aerial vehicle cooperation formation and obstacle avoidance. The control algorithm comprises steps of (1) when an unmanned aerial vehicle formation executes a flight task, detecting positions and speed information of the unmanned aerial vehicles and airspace obstacles through an airborne sensor, and abstracting obstacles in a flight space into ball bodies; (2) according to position information of each unmanned aerial vehicle, constructing an unmanned aerial vehicle formation communication topology, and using a distributed transmission method, achieving information interaction between neighborhood unmanned aerial vehicles in the formation; (3) constructing an unmanned aerial vehicle dynamics model; and (4) when detecting an obstacle, determining a safe distance of obstacle avoidance of the unmanned aerial vehicles, judging whether the distance between any unmanned aerial vehicle and the obstacle in the unmanned aerial vehicleformation meets requirements of the safe distance, and if not, adjusting the formation pattern and carrying out obstacle avoidance through a virtual force strategy. The control algorithm is operable and simple; cooperation formation of multiple unmanned aerial vehicles can be achieved; obstacles can be avoided quite flexibly; and the control algorithm is very important for multi-cooperative combats.
