摘要:
Electrophoretic display units (1) can get a shorter total image update time by generating and supplying at least some of the data independent signals (Sh1, Sh2, S4, Sh5) during the processing of image information (Del). The processing is done to calculate the data-dependent signals (R,Dr). Data-independent signals (Sh1, Sh2, Sh3, Sh4, Sh5) do not depend on this processing, so these signals may be supplied during the processing. The total image update time is formed by the sum of the time required for image processing (Del) and of the subsequent time required to supply the data-dependent signals (R,Dr) to the pixels (11).

A light apparatus includes one or more light pipes and/or diffusers to transfer and/or diffuse light from a few point light sources to a broader area and to other points. A hollow light pipe includes a light transmissive sidewall that encompasses an interior space, which receives and hides control circuitry for the light sources therein. A bottom end surface of the hollow light pipe is disposed adjacent to one or more light sources and transmits the light therefrom over a relatively large, uniform area. A solid core light pipe has a light receiving end and a light dispersion end having a reflective facet therein. The reflective facet includes a depression forming a reflective surface angularly displaced from a longitudinal axis of the solid core light pipe. A light diffuser surrounding a point source of light is adapted to cause the point source to look like a flame. A light apparatus including the hollow light pipe and the solid core light pipe and/or the light diffuser is adapted to provide a plurality of different light effects, including a multi-color light show through the hollow light pipe and a flame flicker effect through the solid core light pipe.

A system, apparatus, and methods for conducting secure online monetary transactions are disclosed. In one embodiment, a networked purchasing system includes a media broker, a physical medium producer for manufacturing branded media, one or more merchants, one or more distributors, a consumer networked computer, a financial institution. A media broker further includes a transaction server and a consumer account database. Branded media is, for example, a prepaid compact disk (CD) gift card activated at the point of sale for conducting online monetary transactions. The branded media provides a secure and anonymous alternative to credit cards for conducting online monetary transactions.
摘要:
A display device (101) has groups of display elements (118), which are changed from one optical state to another optical state by applying a waveform sequence of potential differences. The waveform enables particles (108, 109) to occupy a position corresponding to the other optical state and includes standard reset, over-reset and grayscale drive. The standard reset part of the waveform applies a potential difference, which is proportional to a distance the particles (108, 109) must move to reach one of the extreme optical states and the over-reset is independent of the distance. Grayscale or color scale accuracy is improved and direct charge on a pixel may be balanced over time with consequent grayscale drift compensated by tuning the grayscale driving pulse.

An apparatus, system, and method are disclosed for multistage water separation. A first separation layer separates water droplets from a fuel flow by repelling the first water droplets. A coalescing layer may coalesce fine water droplets in the fuel flow. In one embodiment, a centrifugal separator directs the fuel flow tangentially to a filter wall and the centrifugal force of the fuel flow directed tangentially along the filter wall biases water droplets from the fuel flow. A second separation layer separates second water droplets from the fuel flow.
摘要:
In a transceiver system a first interface receives data from a first channel using a first clock signal and transmits data to the first channel using a second clock signal. A second interface receives data from a second channel using a third clock signal and transmits data to the second channel using a fourth clock signal. A re-timer re-times data received from the first channel using the first clock signal and retransmits the data to the second channel using the fourth clock signal.
摘要:
Methods and apparatus are provided to monitor and analyze activity occurring on a networked computer system. In some embodiments, a method is provided for capturing, in a data structure, at least a portion of a notification describing a network event provided by a node on a computer network, identifying a data element (e.g., an IP address of the node) within the notification, and updating an index and/or summary based on the data element. The data structure may be stored in a file system maintained on a site, and sites may exchange information related to the notification data stored on each. In some embodiments, a query which is issued to a site may be processed using data transferred from other sites, and/or may be split into one or more additional queries which may be transmitted for processing to other sites.
摘要:
Electrophoretic display units (100) comprising pixels (11) situated between a common electrode (6) and pixel electrodes (5) need, for shortening the total image update times, increased driving voltages across the pixels (11) which make disturbances more visible. To camouflage such disturbances, instead of one common electrode (6), different counter electrodes (16,17) coupled to different portions (66,67) of the electrophoretic display panel (60) are introduced. First and second counter electrodes (16,17) receive first and second voltage signals (V16, V17) lik˜ alternating voltage signals having opposite phases. First shaking data pulses (V16-VE1, V16-VE3) are supplied to the first portion (66) and second shaking data pulses (V17-VE2, V17-VE4) are supplied to the second portion (67), which first and second shaking data pulses have opposite amplitudes. Setting signals (S1,S2,S3,S4) supplied during setting frame period (FS) reduce voltage swings at pixel electrodes (5).

An electrophoretic display comprises a matrix of pixels (18) which comprise electrophoretic material (8, 9) being sandwiched between a top electrode (6) and a bottom electrode (5, 5′). An addressing circuit (16, 10) addresses the pixels (18) during an image update period (IUP) by applying drive voltages (VD) between the top electrode (6) and the second electrodes (5, 5′). The drive voltages (VD) having levels in accordance with an image to be displayed on the electrophoretic display. A controller (15) controls the addressing circuit (16, 10) to supply a series of AC-pulses (ACP) between the bottom electrodes (5, 5′) of neighboring pixels (18) to obtain an electric field (LF) being substantially directed in a plane parallel to the bottom electrodes (5, 5′).
