Abstract:
An electronic device includes a storage unit, a sound signal receiving unit, a remote signal generating unit, a processing unit, and a transmitting unit. The control table records RC devices, sound parameters, and control commands. Each RC device is associated with at least one sound parameter. Each sound parameter corresponds to one control command. The sound signal receiving unit receives sound signals. The processing unit determines a sound parameter according to the received sound signals, searches in the control table to determine the control command the sound parameter corresponding to according to a selected RC device, and controls the remote signal generating unit to generate a remote signal corresponding to the determined control command. The transmitting unit transmits the remote signal to the selected RC device.
Abstract:
A projection device with a brightness adjustment function includes a polarization beam splitter (PBS), a light source, a reflective display, a lens module, a power supply unit, a light detection unit and a power controller. The light source emits light to the PBS. The PBS reflects a portion of the light to the reflective display, and transmits a remaining portion of the light. The lens module projects the images. The light detection unit acquires a digital value of a portion of the light reflected by the PBS that is not received by the reflective display, and compares the digital value with a predetermined digital value to generate a control signal. The power controller for adjusts power from the power supply unit to the light source according to the control signal until the digital value matches the predetermined digital value of the light from the light source.
Abstract:
A handwriting input device includes a housing and a nib selectively exposed from a bottom side of the housing or hidden in the housing. The device further includes a pressure sensor, a motion sensor, and a microcontroller. The pressure sensor generates pressure signals when the nib is depressed. The motion sensor senses movement of the device. The microcontroller records the sensed movement upon receiving the pressure signals, and processes the recorded movement to obtain track signals of handwritten information when the duration of not receiving the pressure signals exceeds a predetermined time interval. The track signals of handwritten information are then transmitted to an external electronic device communicating with the device to become handwriting shown on a display of the external electronic device.
Abstract:
A system for modulating audio effects of speakers is provided. The system includes a selecting module, a playing module, a recording module, a time delay computing module and a modulating module. Based on these modules, the system is capable of determining a time difference and a pitch for each of the speakers, and modulating the time difference and the pitch for each of the speakers to a desired time difference and a desired pitch, so as to ensure that simultaneous sounds from each speaker arrive at a microphone at about the same time and with the same audio pitch. A related method is also provided.
Abstract:
A heat dissipation structure includes an electronic device, and a cooling device mounted to the electronic device. The electronic device includes a housing, and a heat generating element mounted in the housing. The housing defines an opening. The cooling device comprises a shell abutting against the heat generating element through the opening, a number of fins extending from the shell, a fan mounted to the shell, an air intake, and an air outlet. The air intake and the air outlet are located outside the housing.
Abstract:
A memory card module includes a first circuit board, and a second circuit board. On one surface of the first circuit board, there are flash memories and a controller. The second circuit board is installed at one end of the first circuit board and is electrically connected with the first circuit board so as to form a transmitting interface port. On a first surface of the second circuit board, there are a plurality of interface connecting points. On a second surface of the second circuit board, part of the second surface is hollowed out. A space formed between the hollowed out area and the corresponding first circuit board increases the area for circuit layouts and the mounting components for the first circuit board. Therefore, quantity of accommodated memory components may be increased so as to increase the total storage capacity of the memory card under limitation of small dimensions.
Abstract:
A slim card reader is disclosed. One end of a shell body has a plugging slot plugged with a memory card, and there are metal connection pins that contact the memory card. The characteristic is the second end of the shell body corresponds to a female plugging slot of the USB port, and on the surface of the end of the shell body corresponding to the female plugging slot, there are a plurality of metal flakes that contact the conducting flakes in the female plugging slot. The key point, which makes a breakthrough in the dimensions of the card reader, is that the present invention doesn't use a conventional USB plugging head design. The metal external mask of the USB plugging head is removed. The limitation caused by the large dimensions of the USB plugging head produced by the format of the metal external mask is overcome.

Abstract:
An electronic cosmetic case includes a stereo image display unit, and a pair of image capturing units. The pair of image capturing units is for simultaneously capturing facial image of a user from two different directions, and providing the captured images to the stereo image display unit. The stereo image display unit receives the two captured images and simultaneously displays one captured image to the left eye and displays the other captured image to the right eye, thus allowing the user to perceive a stereo image.
