摘要:
The present invention provides a system for recording an image onto a label layer of an optical disc. The optical disc also includes a data layer on which a plurality of predetermined address codes is marked. The system essentially includes a multi-focal lens module for dividing a laser beam emitted by an optical pick-up unit into a first beam portion and a second beam portion. The first beam portion is focused on the data layer to locate a first position by retrieving the predetermined address codes. The second beam portion is focused on the label layer to record the image at a second position opposite to the first position.

A telephone ring detector detects a ring signal voltage from a diverse set of signals transmitted on a telephone line before a complete alternating current ring signal cycle is received. In an exemplary embodiment, the ring detector includes a voltage threshold setting device for establishing a voltage threshold and comparing the ring signal voltage to the voltage threshold to provide an output signal when the ring signal voltage is above the voltage threshold. A pair of zener diodes having a selected voltage value can provide the threshold setting and comparison functions. A microprocessor, including a timer for measuring a time duration of the output signal, outputs a ring detection signal when the time duration exceeds a predetermined time interval value, which is substantially less than a full ring cycle. A line switch responsive to the ring detector is provided to direct communication signals to a telecommunications device.

An intraocular pressure detecting device includes an image capturing unit, a processor, and a pressure detection unit. The image capturing unit, coupled to the image capturing unit, is capable of acquiring an eye image. According to the eye image, the processor can determine an intraocular pressure detection area. After the pressure detection unit detects the intraocular pressure detection area, the intraocular pressure is calculated by the processor of the intraocular pressure detecting device.

A data inputting apparatus includes a plurality of keyswitches, an optical module, a sensing module and a processing module. The keyswitches are disposed on the data inputting apparatus. The optical module is disposed on a first side of the data inputting apparatus and is used for emitting a plurality of lights along a first direction, and the lights are corresponding to the keyswitches respectively. The sensing module is disposed on a second side opposite to the first side and is used for receiving the lights and generating a sensing result. The processing module is coupled to the sensing module. When one of the keyswitches is pressed, one of the lights is blocked by the pressed keyswitch resulting in the sensing module adjusting the sensing result, and the position of the pressed keyswitch is determined by the processing module based on the sensing result.

An optical touch apparatus is disclosed. The optical touch apparatus comprises a light emitting module, a noise suppressing module, a light sensing module, and a processing module. The light emitting module emits at least one sensing beam, and the at least one sensing beam comprises a plurality of sensing rays. If an emitting angle of a specific sensing ray among the plurality of sensing rays toward a light sensor of the light sensing module is larger than a default value, the noise suppressing module will block the specific sensing ray from emitting into the light sensor. After the light sensing module generates a sensing result according to the condition of the light sensing module receiving the at least one sensing beam, the processing module will determine the position of a touch point according to the sensing result.
