Abstract: A lamp includes a rotary adjustment mechanism, an inclination adjustment mechanism and a light source. The light source is rotatable along a first direction in a first plane by the rotary adjustment mechanism and/or rotatable relative along a second direction in a second plane by the inclination adjustment mechanism, wherein the second plane is different from the first plane.

Abstract: A lighting device includes a rotating unit, a clutching unit releasably engaging the rotating unit, and a lighting unit connected to the rotating unit. The clutching unit is operable to move between a first position, where the clutching unit engages the rotating unit to limit rotation thereof, and a second position, where the clutching unit disengages the rotating unit to permit free rotation thereof. The lighting unit is adjustable to a desired illumination angle when the clutching unit is in the second position. The clutching unit is moved from the second position to the first position to position the lighting unit at the desired illumination angle.

Abstract: A optical sensing module based on signals having pulse width modulation and a method thereof are disclosed for sensing a light source and providing an output signal having pulse width modulation. The optical sensing module comprises an optical sensor, a signal processing unit, and a duty cycle modulation unit. The signal processing unit provides a modulation control signal based on a sensing signal generated by sensing the light source from the optical sensor in conjunction with a gain control signal. The duty cycle modulation unit modulates the duty cycle of the pulse width modulation input signal to generate the pulse width modulation output signal based on the modulation control signal. The duty cycle difference between the duty cycle of the input signal and the duty cycle of the output signal is proportional to the intensity difference between the light source and a reference light source.

Abstract: A bus system having a transmission interface and a transmission control module built in a processor is provided. The transmission interface receives instruction signals output from the transmission control module and executes a corresponding data transmission process such that fast data transmission between storage unit of the processor and a host port interface (HPI) of a peripheral device may be fulfilled without an action of the processor, so as to avoid a waste of processor resources and an increase of production cost.

Abstract: A selectively-switchable bus connecting device is proposed, which is designed for use in conjunction with a chip device for connecting the multiple signal lines of the chip device's internal bus in a user-specified mapping manner to the multiple signal lines of a socket on an external circuit board. This feature allows chip devices of the same type to be usable for mounting on different types of circuit boards having different socket signal line arrangements, with the benefits of flexible arrangements and cost-effective design and manufacture of circuit boards with chip devices.

Abstract: A bus integrating system is applied to a data processing system. A bus controlling module is coupled to at least one peripheral device for enabling a corresponding device to access data according to a data access request signal sent from the peripheral device. A bus integrating processor includes at least one first bus data access signal pin and at least one second bus data access signal pin, so as to allow the bus controlling module to control peripheral devices connected to buses of a first data transmission standard and a second data transmission standard to perform data access with another peripheral device of the same and different data transmission standard via the single bus integrating processor. Thereby, the bus integrating system allows buses with different data transmission standards to transmit data via a single bus and the integrating bus controlling module.
