Abstract: A tissue engineering scaffold for growing cells can include a plurality of biocompatible microspheres linked together to form a three-dimensional matrix. The matrix can include a plurality of pores for growing cells. The biocompatible microspheres can include first and second sets of microspheres. The first set of microspheres can have a first characteristic, and a first predetermined spatial distribution with respect to the three-dimensional matrix. The second set of microspheres can have a second characteristic that is different from the first characteristic, and a second predetermined spatial distribution that is different from the first predetermined spatial distribution with respect to the three-dimensional matrix.

Abstract: Apparatus and methods for driving a transmitter to generate DNPSK signals is disclosed including generating N data streams comprising data symbols and for each of a plurality of sets of N simultaneous data symbols of the N data streams, imposing signals are on L of a plurality of signal lines, with the value of L corresponding to values of the N simultaneous data symbols. Signals on the plurality of signal lines are ANDed with a clock signal synchronized with the N data streams to produce RZ signals. The RZ signals are summed and the summed signal is input to a laser that produces an output having frequency modulation corresponding to the magnitude of the summed signal. The output of the laser is passed through an optical discriminator.

Abstract: A pivotable folding utility table includes a table top having a pair of support pedestals pivotally attached thereto. A first pivotal support brace, which includes a proximal end and a distal end, is attached at its proximal end to the first support pedestal. A second pivotal support brace, which includes a proximal end and a distal end, is attached at its proximal end to the second support pedestal. The distal ends of the first and second pivotal support braces are adapted to be pivotally attached to a retaining assembly, mounted in relation to the table top. The distal ends of each pivotal support brace are disposed contiguously in relation to each other when engaging the retaining assembly. Specifically, the retaining assembly includes a cross-brace member operably disposed through openings formed in the distal ends of the first and second pivotal support braces, thus providing a pivotal engagement in relation to the table top.

Abstract: A scope may include an adjustment dial, which may be moved among a plurality of positions to configure the scope to compensate for projectile drops. The adjustment dial may be labeled with dial-calibration data, which may include one or more distance indicators and/or one or more windage hold-off indicators. The scope may be attached to a gun and the dial-calibration data may be at least partially generated using ballistics performance data based on shots fired by the gun. The dial-calibration data may be at least partially generated using shooting conditions. An electronic device may include a derived distance calculation module, which may be configured to use a distance to a target and actual shooting conditions to calculate a derived distance. The derived distance may be used in connection with an adjustment dial labeled with dial-calibration data at least partially generated using shooting conditions different from the actual shooting conditions.

Abstract: An ejection inspecting device which inspects an ejection state of an ejection head, including nozzles ejecting fluid, includes fluid receiving areas corresponding to the ejection head so as to receive the fluid ejected from the nozzles. A potential difference generating unit generates predetermined potential differences between the ejection head and the fluid receiving areas. Electrical variation detecting units detect electrical variations of the fluid receiving areas. A control unit drives the ejection head to eject the fluid to the fluid receiving areas from the nozzles in a state in which the predetermined potential differences are generated between the ejection head and the fluid receiving areas by the potential difference generating unit. The ejection inspecting device also inspects the nozzles to determine whether the fluid is ejected from the nozzles on the basis of the detection results of the electrical variation detecting units in the fluid receiving areas.
