Abstract:
The present invention discloses a transflective mode color liquid crystal display, whose white backlight source is composed of several narrowband monochromatic light sources. A color filter for displaying colors is designed to match the wavelength of each of the monochromatic light sources so that the color filter can let a monochromatic light source of one color be transmitted, while selectively absorb the wavelengths of the monochromatic light sources of other colors. The present invention can achieve high color saturation at the backlight mode while maintaining high reflectance.
Abstract:
A power-augmenting gear structure for an electric car includes a low-speed and power-augmenting transmitting route additionally installed in a gear case, with an output shaft of an electric motor extending in the gear case. The gear case has transmission gears forming conventional normal speed transmitting routes with normal speed reducing ratio for running on common flat roads, and a low-speed and power-augmenting transmitting route to be used in case of moving up an upward slope or coping with a condition needing a large torque. Then the electric motor may be reduced in its size, weight and cost, without necessity of enlarging it to have a large power.
Abstract:
A portable memory device having a flexible polymeric display panel which comprises a memory controller configured to determine memory information from a memory coupled to the memory controller, generate memory information signals in dependence on the determined memory information and output the memory information signals to a display driver. The display driver is configured to convert the memory information signals into visual representation signals. The visual representation signals are then outputted on the flexible polymeric display panel. In one embodiment, a secure digital (SD) flash memory card has an electrophoretic display on the card housing and the display indicates information such as the amount of storage available in the card.
Abstract:
Disclosed are methods, systems and apparatuses for harvesting vibrational energy from vehicles, as well as methods for locating vibrational energy on a vehicle. One harvesting apparatus comprises a vibrational energy harvester coupled to a substantially maximal vibrational displacement node of the structural element of a vehicle, and tuned to a frequency of vibration of the maximal vibrational displacement node. The harvester may be one of a variety of harvesting devices, such as piezoelectric devices. Methods are also provided to locate structural elements which are appropriate for vibrational energy harvesting.

Abstract:
A controlled stepping motor is electrically connected to a controller and a loading device. A method of controlling the stepper motor includes utilizing the controller to output a control signal to the stepping motor according to a target displacement and a first index parameter, utilizing the stepping motor to move the loading device according to the control signal, utilizing the controller to calculate a difference between the target displacement and an actual displacement of the loading device, and utilizing the controller to generate a second index parameter for updating the first index parameter according to the first index parameter, the difference, and the actual displacement.
Abstract:
A pet housing includes a top portion having a continuous edge and a bottom portion having a continuous edge. A middle portion is disposed between the top and bottom portions. The middle portion includes a continuous top edge and a continuous bottom edge. A first zipper is operable between an open and closed position to selectively interconnect the top portion continuous edge to the middle portion continuous top edge. A second zipper is operable between an open and closed position to selectively interconnect the bottom portion continuous edge to the middle portion continuous bottom edge. When the zippers are in the closed position, the top, bottom and middle portions form an enclosed area. When the zippers are in the open position, the top and bottom portions are completely detachable from the middle portion to allow the portions to nest.
Abstract:
A network switch includes a first queue that receives a first packet. A second queue receives a second packet. A queue control module determines a desired output time slot of the first packet based on an arrival time and an output rate associated with the first packet, determines a length and a scheduled output time slot of the second packet, and selectively outputs the first packet before the second packet based on the desired output time slot, the length, and the scheduled output time slot.
