    Abstract: A multi-axis gimbal assembly includes a spherical armature, a first coil, a second coil, a third coil, a bracket, a stator, and a motor. The spherical armature has first, second, and third perpendicularly disposed axes of symmetry. The first coil is wound about the first axis of symmetry, the second coil is wound about the second axis of symmetry, and the third coil is wound about the third axis of symmetry. The bracket is rotationally coupled to the spherical armature to allow relative rotation between the spherical armature and bracket around only the first axis of symmetry. The stator is rotationally coupled to the bracket to allow relative rotation between the stator and bracket around only the second axis of symmetry. The motor is coupled to the stator and is configured to simultaneously rotate the stator, the bracket, and the spherical armature around the third axis of symmetry.

  • Patent number: 9742382
    Abstract: A flip-flop circuit may include a first latch and a second latch. The first latch, which may operate as a “master” latch, includes a first input terminal to receive a data signal, a second input terminal to receive a clock signal, and an output terminal. The second latch, which may operate as a “slave” latch, includes a first input terminal connected directly to the output terminal of the first latch, a second input terminal to receive the clock signal, and an output terminal to provide an output signal. The first latch and the second latch are to be clocked on the same phase of the clock signal, thereby eliminating the need to include clock inversion circuits that generate complementary clock signals.

  • Patent number: 9350325
    Abstract: A CMOS D-type flip flop (D-FF) exhibits reduced power consumption by selectively disabling certain charging/discharging operations at specific circuit elements to minimize the capacitance of the circuit's internal nodes using a partial signaling technique. A clock inverter module may be used to provide a partial inverse clock signal that is the complement of a clock signal when a non-clock dependent input to the clock inverter module has a first value and to provide a fixed signal when the non-clock dependent signal has a second value. One or more MOSFETs controlled by the partial inverse clock signal do not charge or discharge when the non-clock dependent signal has the second value.

  • Publication number: 20120272302
    Abstract: Techniques for generating a human user test for online applications or services may include splitting the visual objects in an image into multiple partial images, and forming one or more alignment positions. At each of the alignment positions, some of the visual objects appear recognizable while some bogus visual objects also appear to prevent robots from recognizing the alignment positions. A user is requested to find the multiple alignment positions to return recognizable visual objects. A system determines that the user is a human user if the recognizable visual objects input by the user match the visual objects in the image.

  • Publication number: 20060172958
    Abstract: Phospholipid scramblase 3 (PLS3) is a newly recognized member of a family of proteins responsible for phospholipid translocation between two lipid compartments. A novel isoform of PLS3 is identified and characterized herein. The function of PLS3 in mitochondria was disrupted, yielding an inactive mutant PLS3(F258V). Cells transfected with PLS3(F258V) exhibited reduced proliferative capacity that was unaffected by the presence of Na3N. PLS3(F258V)-expressing cells exhibit abnormal mitochondrial metabolism and structure and were associated with decreased sensitivity to UV- and tBid-induced apoptosis, and diminished translocation of cardiolipin to the outer mitochondrial membrane. Cells transfected with wild-type PLS3 displayed increased sensitivity to apoptosis and enhanced cardiolipin translocation. These studies identify PLS3 as a regulator of mitochondrial structure and respiration, and cardiolipin transport in apoptosis.
