An assembly design for an oscillating resonator-based sensor where an oscillating crystal resonator such as a quartz crystal resonator is rigidly affixed or ‘mounted’ onto a solid substrate in such a fashion that the resonator can either rest flush against the substrate surface or upon a rigid mounting adhesive. Once cured, the mounting adhesive forms a liquid tight seal between the mounted resonator and the substrate such that only the sensing electrode surface will be exposed to fluids applied to the front side of the substrate. The mounted resonator assembly is designed in such a way that it can be interfaced with a fluid delivery system to form a liquid tight chamber or flow cell around the mounted resonator without incurring additional physical impact upon the mounted resonator. The assembled flow cell can in turn be used to direct multiple fluid streams to flow in a laminar manner over the sensing surface of the mounted resonator and by varying the rates of flow for the different laminar flowing fluid streams the total hydraulic pressure exerted on the surface of the mounted resonator can be held constant.

A travel control method for a self-propelled carriage having a travel control section for controlling steering-driving wheels. In the method, the steering-driving wheels are steered by a predetermined angle based on a direction change command, and in this state, the carriage is moved forward and backward for a predetermined distance to make the carriage depart from a base line. Then, the carriage is steered toward the base line to return to the base line. After that, the carriage is made to be able to travel along the base line.
