摘要:
A positioning method for a touch display panel is provided. The touch display panel includes a touch panel and a display panel. The display panel is disposed on the touch panel, and sensing points and reference positions are set on the touch panel. In the method, pressures with different values are repeatedly applied to each reference position; under the pressures with the different values, average capacitance values of the reference positions corresponding to the sensing points are established. When an object touches the display panel, the sensing points of the touch panel correspondingly generate second capacitance values. Under a touch pressure value, the average capacitance values of the reference positions corresponding to the sensing points are selected. The second capacitance values and the average capacitance values of the reference positions corresponding to the sensing points under the touch pressure value are calculated to obtain a touch position of the object.

The present invention provides a network unit replacing method for an embedded system device having an internal network unit and a related embedded system device. The network unit replacing method comprises: detecting a network unit type of the embedded system device, to generate a detecting result; and when the detecting result indicates that the embedded system device has at least an external network unit currently, initializing the external network unit to make the embedded system device access network via the external network unit instead of the internal network unit.

A power regulator, power control system and the method thereof are provided. A detecting device receives a feedback signal from a resistive load device, and outputs a control signal, which could be a voltage or a current. While receiving the control signal, the power regulator outputs a drive voltage in a proportional way. In the proportional way, full power drive voltage is outputted in a continuous output time period and is stopped outputting in a continuous non-output time period. The resistive load device receives the drive voltage and then outputs the feedback signal to the detecting device. Similarly, in the proportional way, the full power drive voltage is outputted in the continuous output time period and is stopped outputting in the continuous non-output time period. Thus, it is able to decrease the amount of harmonic waves.

A webcasting system and the audio data regulating methods to be used in the webcasting system are presented. The webcasting system includes a host and an audio playing apparatus. The host, which is loaded with an operating system and drivers, determines the audio data output according to an expected data received by the operating system. The drivers provide the expected data according to the audio data received and transform the audio data for network transmission. The audio playing apparatus receives the network data and processes the network data for audio playing.

A maintenance apparatus and a maintenance method for a probe card are provided. The maintenance apparatus includes a first supporting member, a second supporting member, a first clamping member, a second clamping member, and a plurality of locking units. In the maintenance method, the first supporting member and the second supporting member are initially positioned underneath below the two sides of a positioning slice, respectively, and then the first clamping member and the second clamping member are each disposed on the first supporting member and the second supporting member, respectively. First clamping member and first supporting member, and second clamping member and second supporting member are secured together respectively by locking units. Thus two sides of positioning slice are secured tightly and the positioning slice is well fastened. A probe card is also provided. The probe card includes a guide slot having a size corresponding to that of maintenance apparatus.

An uniformly self-luminous keyboard device comprises a housing and a keyboard unit. The housing includes an upper casing and a lower casing, which can be assembled together. After the upper casing and the lower casing are assembled together, an accommodation space is formed therebetween. The upper casing has an opening interconnecting the accommodation space. The keyboard unit is arranged in the accommodation space and includes a plurality of press members passing through the opening and moved by a force to have a displacement, and a baseplate supporting the press members. A light conduction space is formed between the baseplate and the lower casing. A light emitting unit is arranged inside the light conduction space. The height of the light conduction space decreases with the distance to the light emitting unit, whereby light is uniformly distributed over the bottom of the keyboard unit. Thus is achieved the uniformly self-luminous keyboard device.

A luminous keyboard comprises a housing, a keyboard and a light emitting portion. The keyboard and light emitting portion are held in the housing. The light emitting portion includes at least one housing trough and a lighting element held in the housing trough. The housing trough has at least one first recess portion and at least one second recess portion on the periphery. The first recess portion and second recess portion have respectively an inner wall formed a first curved surface and a second curved surface. The lighting element generates light projected to the first and second recess portions, and the light piercing through the first and second curved surfaces is transmitted towards the concave directions of the first and second recess portions. Thus the light advancing direction in the light emitting portion can be effectively controlled.

A roof ventilation assembly has a ridge framework corresponding to a vent on a roof, a top cover, front and rear panels and two baffler assemblies. The two baffler assemblies are respectively mounted on two sides of the ridge framework leaving two gaps between the baffler assemblies and the top cover. When heated air under the roof rises, the heated air goes through the vent and out of the slots. Therefore, the heated air can be expelled by the roof ventilation assembly cheaply and easily, without requiring maintenance and external power source.
