摘要： A statistical method is used to separate periodic from non-periodic vibration peaks in machine vibration spectra. Generally, a machine vibration spectrum is not normally distributed because the amplitudes of periodic peaks are significantly large and random relative to the generally Gaussian noise. In a normally distributed signal, the statistical parameter Kurtosis has a value of 3. The method sequentially removes each largest amplitude peak from the peaks in a frequency region of interest in the spectrum until the Kurtosis has a value of three or less. The removed peaks, which are all considered to be periodic, are placed into a candidate peak list. As the process of building the candidate peak list proceeds, if the kurtosis of the remaining peaks in the frequency region of interest falls to three or less, the process stops and the candidate peak list is defined.

摘要： A locomotive consist including a pair of fuel-electric locomotives, each having a prime mover engine and a power transmission system including a main generator and traction motors coupled to driving wheels, a high voltage electrical connection operable in an on state or an off state, and a computer controller. The pair of fuel-electric locomotives is configured to selectively cooperate to operate in three different operating modes as controlled by the computer controller: (1) a prime mover mode, (2) a mother/slug mode, and a mother/inoperative mode.

摘要： A scarecrow includes a scarecrow body corresponding generally in shape to a body of a live animal; and an assembled and balanced hollow head of molded plastic construction corresponding in shape to a head of the live animal. The assembled and balanced head includes a front face portion and a rear head portion fixed together to form the head. The front face portion has a first thickness and the rear head portion has a second thickness, the front face portion and the rear head portion being unequal in weight, with the rear head portion having selected areas on an interior surface thereof that are thicker than the first thickness and define an offset weight so that the assembled head is substantially balanced as assembled. An unstable mount is disposed between the body and the head onto which the head is rotatably mounted for 360-degree movement of the head to the body without interfering with free movement of the head, the head being balanced on the unstable mount.

摘要： A pipette-fillable fluid reservoir body. The fluid reservoir body includes two or more discrete fluid chambers therein. At least one of the fluid chambers contains a pressure compensation device and at least another one of the fluid chambers is devoid of a pressure compensation device. Each of the fluid chambers is in fluid flow communication with a fluid supply via, and each of the fluid chambers have sidewalls and a bottom wall attached to the side walls, wherein the bottom wall slopes toward the fluid supply via. The fluid reservoir body also includes an ejection head support face in fluid flow communication with the fluid chambers for attachment of a fluid ejection device to the ejection head support face for ejecting fluid from the fluid chambers.

摘要： A unitary, molded fluid reservoir body to which a fluid ejection head substrate is attached. The unitary, molded fluid reservoir body includes one or more discrete fluid chambers therein. Each of the one or more fluid chambers have an open top, side walls, and sloped bottom walls attached to the side walls, wherein each of the one or more fluid chambers terminates in a fluid supply via, and wherein the sloped bottom walls have an angle ranging from about 6 to about 12 degrees relative to a plane orthogonal to the sidewalls. An ejection head support face is disposed opposite the open top for attachment of a single fluid ejection device to the ejection head support face for ejecting fluid provided from the one or more chambers through the one or more fluid supply vias.

摘要： A vibration analyzer for use in determining a rotational speed. The vibration analyzer includes an input for sensing vibration data, a memory for storing the vibrational data, and a processor. The processor produces a spectral plot of the vibrational data, locates peaks in the spectral plot, receives an input rotational speed, and scans the spectral plot in predetermined rotational speed increments to provide a candidate rotational speeds. For each candidate rotational speed, a number of associated harmonics is identified, closest peaks in the spectral plot to the candidate rotational speed and its harmonics are located, gaps between the closest peaks and the candidate rotational speed and its harmonics are measured and summed, and a sum of the gaps is recorded. The candidate rotational speed that is associated with a minimum sum is selected as the nominal rotational speed.

摘要： A liquid crystal display (LCD) device and an organic light-emitting diode (OLED) display device are disclosed. The LCD device includes a base substrate, a display module, and a liquid crystal lens layer. The display module includes a fingerprint recognition sensor. The OLED display device includes a base substrate, a fingerprint recognition sensor, a two-layered liquid crystal lens layer, and an OLED display. The liquid crystal lens layer is configured to be switchable between a non-lens state and a lens state. By adopting liquid crystal lenses with holes, utilization of reflected light reflected by a fingerprint can be improved and imaging quality can be optimized.
