摘要： Disclosure is to a mobile apparatus having an optical indexer, and a method for performing indexing. The mobile apparatus includes an optical indexing module for sensing a movement. A control interface is generated in simulation and displayed on the mobile apparatus as it apparatus operates as a computer mouse. In the method, the simulated control interface is initiated in the beginning. The optical indexing module is activated to perform a tracing process, in which the optical indexing module emits a light and receives, especially by the multiple sensing cells arranged in an array, the reflected light. The photo energy received by the every sensing cell within a time slot can be computed. The energy difference in the time slot is used to determine a moving direction. An indexing signal is generated by converting movement signal made by optical indexing module and control signal from the simulated control interface.

摘要： Disclosure is related to an optical sensor array apparatus. According to one embodiment of the invention, multiple sensor pixels are arranged as an array and forming a sensor array. Every comparator circuit is connected to one sensor pixel so as to calculate its energy state. A light source such as laser is installed in the apparatus. A control circuit is provided to recognize the sensor pixels' energy states for determining the spatial interference difference made by the reflected ray. The sensor array apparatus may be adapted to various surfaces since the light intensity and exposure time is able to be modulated as a compensation mechanism.

摘要： An active mixer with self-adaptive bias feedback is described and resolves a poor linearity, inconvenient design of a bias circuit, and other defects of a conventional mixer. The dual self-feedback bias structure according to this invention is used. The active mixer with self-adaptive bias feedback has a power supply, an RF input match/drive unit, a local oscillator input match/drive unit, a mixer core unit, a self-adaptive twin bias circuit and an IF output match/buffer unit. This invention improves the linearity of a conventional mixer and does not affect other characteristics. There are fewer components in this invention; an area of the mixer is thus smaller. Further, this invention may improve temperature response, increase yield factor, and lower unit cost. The dual self-feedback bias structure is designed for further application to other semiconductor manufacturing processes, components, and microwave products.

摘要： A linearized bias circuit with adaptation resolves the problem happening to the power amplifier with conventional bias circuit that the DC and AC characteristics of the power amplifier shift or even deteriorate due to a temperature variation. The linearized bias circuit with adaptation has a reference voltage source, a first voltage source, a first resistor, a second resistor, a first NPN transistor, a second NPN transistor, and a third NPN transistor. The present invention has the characteristics of bias current temperature compensation, gain and phase compensations to achieve high linearity for the conventional power amplifier and reducing the DC consumption power. At the same time, the quantity of the required elements and layout area in the present invention are small so that the design complexity can be reduced for improving yield, reducing IC layout area, and reducing cost.

摘要： An SCR provides for increased holding voltage by decoupling the pnp and npn parasitic bipolar transistors of the SCR. In one embodiment, a N+ region is placed between the n+ region and the p+ region normally associated with conventional SCR devices, to formulate a new resistance. The new resistance is manifested to allow more current to flow through the new resistance rather than through the SCR parasitic pnp bipolar transistor. Since the parasitic pnp bipolar transistor no longer turns on as strongly as it would otherwise without the low resistance path through the new resistor, the holding voltage of the SCR is raised.

摘要： A constant power control device of an active vaporization suction apparatus includes a power unit, a first load matching unit, a matching control unit, a second load matching unit, and a constant current generation unit. To replace a medication box along with a liquefied medication within, a new medication box is mounted on the constant power control device, and the first load matching unit is electrically connected to a load unit of the replaced medication box. The first load matching unit determines a load value of the load unit. The second load matching unit and the constant current generation unit generate a constant current signal according to the load value, and transmit the constant current signal to the load unit, thus allowing the load unit to vaporize the liquefied medication with a constant power. The present invention prevents the constant power from changing due to medication box replacements.

摘要： Disclosure is related to a cursor control apparatus and a method for controlling the cursor. The cursor control apparatus essentially includes a light-emitting unit for emitting lights, a housing having a light passage thereon, a light-sensing unit and a control unit. The lights are emitted to outside the apparatus via the light passage. The light-sensing unit then receives the reflected lights from a surface via the passage, especially the lights reach a plurality of sensing cells arranged in an array. The control unit is used to control the energy of the emitting lights, and control the light-sensing unit to receive the lights. After that, the energy received by every sensing cell in an interval can be computed and find the spatial interference difference of energy. The difference is made to determine a moving direction, for example the cursor's movement with the movement of user's finger around the light passage.
