    The present invention provides an assistant apparatus for surmounting a barrier, which comprises a carrier body, an assistant mechanism, and a sensing/driving apparatus. The assistant mechanism, disposed at a side of the carrier body, having an assistant block disposed at the end thereof, functions to place the assistant block on the ground between the carrier body and the barrier so that the carrier body is capable of surmounting the barrier through the assistance of the assistant block. The sensing/driving apparatus, coupled to the assistant mechanism, functions to drive the assistant mechanism to generate the adjusting movement according to whether the barrier is detected or not. By means of the design of the present invention, the assistant block is adopted to reduce the height surmounted by the carrier each time so that the carrier is capable of surmounting the barrier section by section.

    This invention provides a method for power-efficient transmission supporting integrated service over WLAN. The said invention combines the polling-based and the contention-based mechanisms, named on-demand polling (ODP). In the ODP scheme, a voice station is in the polling list when it is in the active mode. During the idle mode, it is configured to operate in the sleep mode for saving power. Also, it adopts the contention-based mechanism to join the list again while returning from the idle mode. On the other hand, the data station adopts the contention-based mechanism to transmit its packets over WLAN. In addition, to achieve service differentiation, the said invention also employs a prioritized access probability for voice over data services. Simulation results show that the said invention can reduce the power consumption for voice stations and enhance the throughput for data stations.

    In this invention, a closed-form integral model for on-chip suspended rectangular spiral inductor is presented. The model of this invention bases on the Kramers-Kronig relations, field theory, and solid state physics to characterize a spiral inductor which RFIC designers could easily have the optimal design utilizing this analytical method. Meanwhile, this model can provide satisfactory prediction to the inductance and self-resonant frequency of the spiral inductor without complicated geometry analysis. Furthermore, unlike conventional formulations only based on circuit parameters, this model could safely predict the inductance and the self-resonant frequency when altering the material (excluding ferromagnetic materials) of a spiral inductor.

    The present invention discloses a sensing device, wherein a hemispherical container containing a liquid dielectric, and the hemispherical container has more than two pairs of electrodes, and the liquid dielectric can trigger the conduction states of the electrodes. A corrosion-resistant material envelops the container. A precision valve is arranged in the container and used to adjust the level of the liquid dielectric and the sensitivity of the sensing device. A buffer necking part is also arranged in the container and used to prevent from non-expected vibration-induced contact between the electrodes and the liquid dielectric. A leakage-proof detection device envelops the hemispherical container, the liquid dielectric, the precision valve, and the buffer necking part and functions to prevent from the leakage of the liquid dielectric. Thus, the present invention can provide an adjustable multi-directional tilt-sensing device for level control.
