  • Publication number: 20230305147
    Abstract: A system having an illumination source configured to illuminate a target object using broadband laser light. A dispersive element is configured to spectrally separate light received from the target object into different colors A focal plane array (FPA) is configured to: (1) receive the light from the dispersive element; (2) acquire spatial information regarding the target object in one dimension in the plane of the FPA; acquire spectral information in a second dimension in the plane of the FPA, wherein the second dimension is perpendicular to the first dimension; (4) obtain information regarding a distance from the FPA to the target object by obtaining different times of flight of at least two wavelengths; and (5) detect a single photon of light, thereby hyperspectrally imaging the target object in three dimensions.

  • Publication number: 20090018545
    Abstract: An automatic bone traction device for correction bone deformities is disclosed. The automatic bone traction device can include a main body, a step motor, a series of transmission gears, and connectors. In one implementation, the step motor operates at a speed of eight steps per second, and the series of transmission gears can step down the motion of the step motor to two revolutions per day. The generated driving torque is then transmitted to a bone distractor, such as a commercially available intermittent distractor. The automatic bone traction device is capable of activating the bone distractor continuously at a rate of two revolutions per day. Advantageously, a flexible shaft is used to connect between the transmission gear assembly and the bone distractor. The flexible shaft allows the main body of the bone traction device to be mounted away from the bone distractor at a convenient location for the user.
