An illumination assembly includes a substrate, a wiring structure, a reflecting layer and a plurality of light-emitting diodes. The wiring structure is formed on a part of the substrate, and includes a catalyst layer covering the part of the substrate, and a conducting layer formed on the catalyst layer. The reflecting layer is formed on another part of the substrate that is exposed from the wiring structure. The light-emitting diodes are disposed on the wiring structure and are electrically connected to the wiring structure.

A light emitting device includes a heat sinking substrate, an electrically insulating layer partially formed on the heat sinking substrate, a circuit pattern layer formed on the electrically insulating layer, a light emitting diode (LED) chip, and an electrically insulating and thermally conductive interlayer. The LED chip is indirectly and non-electrically mounted to the heat sinking substrate. The electrically insulating and thermally conductive interlayer is interposed between the bottom portion of the LED chip and a portion of the heat sinking substrate exposed from the electrically insulating layer. A bottom portion of the LED chip bridges the electrically insulating and thermally conductive interlayer and the circuit pattern layer.

Method and device for light signal reception. This device can selectively execute a comparison mode or a gain mode. In the device, a transmitter transmits a light beam to a target. A receiver receives the light beam reflected from the target and outputs a corresponding received signal. In the comparison mode, it is determined whether a pulse in the received signal is higher than a reference voltage level. When the pulse is higher the reference voltage level, the pulse is outputted. The gain mode is executed and the received signal is amplified and output when no pulse is higher than the reference voltage level in the received signal. The method and device of the present invention can be applied to range finders, the comparison mode is executed during short-distance measurement and the gain mode is executed during long-distance measurement thereby measuring the target distance from several meters to a thousand meters.

A Rangefinder capable of long and short distance measurement in company with compass measurement. The rangefinder includes distance measurement unit, a compass sensing unit and a processor. The rangefinder can selectively execute a comparison mode or a gain mode. The comparison mode is executed during short-distance measurement and the gain mode is executed during long-distance measurement. The compass measurement unit senses a terrestrial magnetism to obtain first and second magnetic sensing signals. The processor estimates a distance between the target and the rangefinder according to the measurement signal from the distance measurement unit and determines a compass orientation of the target according to the first and second magnetic sensing signals.

Rangefinder and measuring method

A method of measuring the azimuth and resetting to zero azimuth automatically is disclosed. Multiple azimuths in longitudinal and latitudinal orientations are sampled by two orthogonal magnetic sensors installed in an azimuth meter, and then are output by corresponding first and second sine wave signals. These two sine wave signals are normalized by adjusting them to be of equal amplitude. The maximum and minimum values of the normalized sine wave signals are used to compute the average values of the respective normalized sine wave signals being of equal amplitude on the positive and negative sides. The resultant sine wave signals serve as the zero reference values for comparison with subsequently taken measuring signals to yield the actual azimuth. The numerical computation for the azimuth can be performed by a microprocessor with accuracy and high speed.
