20110284334Suitcase Having A Shock Absorbing Function - A suitcase includes a case body having a housing and a protective cover covering the housing of the case body. The protective cover has a plurality of air cushions abutting the housing. Thus, the protective cover entirely covers the housing to protect the housing so as to prevent the housing from being scratched, worn or broken due to hit or collision by a foreign object. In addition, the air cushions are located between the protective cover and the housing so that when the protective cover is subjected to an external force, the air cushions of the protective cover provide an elastic buffering effect to the housing of the case body so as to protect the housing of the case body.11-24-2011

20100320289STRUCTURE OF SPRAYING DEVICE - A spraying device includes a control handle, a first hollow barrel, a second hollow barrel, a driving unit, a spraying tube, and a liquid ejection tube. With the driving unit that is driven by high pressure air to rotate received inside the second hollow barrel, when the control handle is operated to supply high pressure air to drive the driving unit to rotate in high speed, the spraying tube is caused to rotate with a high speed, making high pressure rotating air ejected from the spraying tube inducing repeated and rotating impacts on a surface to be cleaned to thereby improve the effect of dust removal. Further, the liquid ejection tube is located within the spraying tube and ejects a stream of water (or cleaning agent), which is mixed with the high pressure air to generate a high speed rotating impact to also realize surface rinsing of an object.12-23-2010

20090220219Delta-Sigma Modulator for a Fan Driver - A fan driver circuit for powering a fan with a linear voltage may be designed using digital design techniques, resulting in a testable, accurate circuit on a smaller die size. The fan driver circuit may be configured to receive a digital control signal, which may be a sequence of numeric values, e.g. multiple-bit binary numbers, each indicative of a desired present rotational speed of the fan. The fan driver circuit may be implemented using a digital modulator, e.g. a delta-sigma modulator, with a simple low-pass filter, e.g. an RC-filter at the output, and may use oversampling based on a system clock, to shift in-band noise to out-of-band frequencies, and digital interpolation to filter out unwanted images from the upsampled digital control signal. The delta-sigma modulator may be constructed as a first-order delta-sigma modulator using an error-feedback structure to reduce die size.09-03-2009
20100215510RPM Controller Using Drive Profiles - A control circuit for controlling the rotational speed of a fan may include a memory element to store operating data corresponding to an operational profile of the fan defined by RPM (revolutions per minute) versus temperature, with the operating data comprising a respective temperature value and a respective RPM value for each respective operating point representing a change in slope of a function that corresponds to the operational profile of the fan. A processing unit may operate to receive a present temperature value, retrieve the operating data from the storage unit, and identify a pair of consecutive operating points such that the present temperature value is greater than a lower respective temperature value of the pair of consecutive operating points, and lower than a higher respective temperature value of the pair of consecutive operating points. The processing unit may calculate a desired RPM value corresponding to the present temperature value by performing linear interpolation between the pair of consecutive operating points, and output the desired RPM value to a closed-loop fan controller configured to control a rotational speed of the fan according at least to the desired RPM value.08-26-2010
