Abstract: A computer accessory device—USB sharer includes a multiplexer, which is connected to a computer host, a human interface device (HID) chip, which is connected to one output end of the multiplexer, a device output end, which is connected to another output end of the multiplexer; and a busyness detection module, which is connected to the middle of the HID chip and the device output end. The USB sharer may reach a sharing function of “N to 1” by applying N?1 sets of “2 to 1” sharer, in which, at least one “2 to 1” sharer's output end is connected to the device output end and, for other N?2 sets of “2 to 1” sharer, of which at least one output end is connected to the input end of another “2 to 1” sharers.

Abstract: A USB hub structure comprises a main body, a plurality of downlink ports disposed directly on the main body, a uplink port connected to the main body with a cable and a downlink port extended outside of the main body and connected to the main body with another cable. Whereby, the uplink port and the downlink port extended outside of the main body can be engaged with each other and integrated at one side on which the downlink ports are disposed so that the structure is convenient to be carried and the downlink ports disposed on the main body can be protected.

Abstract: The invention is a portable device utilizing a vehicle audio system for playing music of specific format.

The USB sharer may reach a sharing function of “N to 1” by applying N-1 sets of “2 to 1” sharer. Wherein, at least one “2 to 1” sharer's output end is connected to the device output end and, for other N-2 sets of “2 to 1” sharer, of which at least one output end is connected to the input end of another “2 to 1” sharers.

Abstract: The present invention is related to a device for USB interface identification, wherein a universal serial bus (USB) connection interface is installed on one side of computer exterior as a connection for external electronic apparatus, and more specifically, the present invention installs a decision circuit connecting to a display device between the USB connection interface and the electronic apparatus. Thus, messages illustrated on the display device are employed by user to determine whether the transmission speed between the computer and the electronic apparatus is in the low speed, full speed, or hi-speed.

Abstract: The present invention discloses a PS2 simulator installed at a PS2 interface of a computer so as to simulate signals from a keyboard and a mouse such that the computer using an earlier OS version is booted after one of the signals is detected. Therefore, a KVM switching device based on other interface specifications such as USB and IEEE 1394 can be used.

Abstract: The invention, a connecting device of PC camera and illuminating lamp, includes an illuminating lamp, which generates a light source; a light-sensing element, which receives an outside image and converts it into electronic signal, and a detector is arranged therein to sense the outside light source and digitize it; a controlling calculation unit, which receives the light source's signal data transferred from the light-sensing element and processes it and, by making a data comparison between the light source's illumination sensed by the detector and a software storage unit, a switch of the illuminating lamp may be automatically controlled thereby; and a connecting interface, which is connected in electricity and signal to a specific interface of a computer.

Abstract: The invention that discloses a switching device for common keyboard, screen, and mouse can make several sets of computer hosts (CPUs) alternatively use a keyboard, a screen, and a mouse, etc., and through the invention, any set of computer may be chosen to be connected to those keyboard, screen, and mouse. The invention includes a human interface device processing unit, a compiler, a multiplexer, and a hub. The human interface device processing unit may process the signal of a human interface device (HID). The compiler has a firmware to receive the signal output from the human interface device processing unit. The multiplexer is controlled by the signal output from the compiler to decide in choosing which computer host to be connected. The hub is controlled by the human interface device processing unit to be acted as a signal assembly-and-transmission.
