Abstract: A laser assembly is provided that includes a laser resonator that emits a first light having a first pulse width, and a trigger assembly electrically coupled to the laser resonator to actuate the laser resonator. The laser assembly also includes a sensor configured to detect the first light as the light emits from the laser resonator, and one or more processors coupled to the trigger assembly. The one or more processors are configured to obtain a first time delay interval from when the trigger assembly is actuated to when the sensor detects the first light, and actuate the laser resonator to emit a second light having a second pulse width based on the time delay interval determined.

Abstract: A method for forming a phantom for an optoacoustic probe is provided that may include forming a scattering material. The method may also include forming an absorbing material, and mixing the scattering material with the absorbing material to form a tissue material. The method can also include mixing the tissue material with a urethane solution to form a phantom material, and curing the phantom material to form the phantom.

Abstract: The invention relates to a low pressure extruder (3) for manufacturing a low density plastic composite material, characterized in that, the volume between the cylinder and the screw per unit length is not decreased along the direction from the hopper to the die in order that the mixture is extruded at low pressure in the melted state out of the cylinder of the extruder; the die is heated by the heater to maintain the melted state of the material in order not to create resistance to the flow in the process of pushing the material mixture out of the cylinder of the extruder. Furthermore, the present invention provides a method and equipment for manufacturing this material.

Abstract: The present invention relates to moving apparatus based on bearing points created by ends of lever arms with changeable length. The lever arm comprises two main components: body and end of lever arm. Lever arm body moves spirally or pendulously around the axis which is different from its axis, end of lever arm moves in and out along the lever arm body. The combination of movement of body and end of the lever arm creates bearing points of the apparatus on the terrain, thus creating capability to overcome barricades of the apparatus. Moreover, the combination of these two movements, when following appropriate principles, creates equilibrium for the frame of the apparatus on various terrains.

Abstract: The invention relates to a multiple-layer composite board of discrete materials and plastic. The multiple-layer composite board of discrete materials and plastic is formed by providing independently stratified plastic layers and discrete material layers, which are pressed in melting state of the alternate plastic layers and discrete material layers and cooled. Due to this stratification, centralized plastic layers constitute high load capacity and discrete material layers pressed with pressure lower than normal extrusion process constitute low density for the multiple-layer composite board of discrete materials and plastic.
