An electronic cigarette has two tubes that resemble a cigarette: an electronic inhaler and an electronic atomizer. The two tubes are connected through one or more electric connectors to form an electronic cigarette. Inside the inhaler is a rechargeable or non-rechargeable power source such as a battery, which supplies electric power to the electronic inhaler and atomizer and ensures that both work together like a cigarette. In addition to the power source, the inhaler also includes other major components: an electric airflow sensor to detect air movement generated by a user's inhaling or puffing act and a Single Chip Micyoco which controls the atomization process. The sensor's role is to collect an airflow signal that triggers the Single Chip Micyoco, which in turn instructs the electronic cigarette to supply electric power to the inhaler and atomizer connected through an electric connector. Inside the electronic atomizer are an electric connector, electric heating wire, liquid container, and atomizer cap with an air-puffing hole. The user inhales through the air-puffing hole at an end of the electronic cigarette to create an air inflow, which triggers the atomization process. The Single Chip Micyoco driven by a software program controls the electronic cigarette in an on / off manner according to the signal detected by the electric sensor on the airflow and completes a cycle of atomization, which converts a solution of a liquid form inside the liquid container to a gas form. This entire process achieves the emulated smoking process of a user, who is satisfied with scent taste that mimics cigarette smoking.

An interior rearview mirror assembly for a vehicle includes a prismatic mirror element and a display element. The prismatic mirror element includes a wedge-shaped prism element having a front surface and a rear surface and a second element having a transflective reflector on a first surface thereof.

The transflective reflector coated first surface of the second element is attached to the rear surface of the prism element via an optically matching medium. The display element is positioned to the rear of the prismatic mirror element and operates to display information through the prismatic mirror element so as to be viewable by a driver of the vehicle when the display element is operated to emit visible light.

An autonomous vacuum cleaner comprises: obstacle detection sensors; moving means; a cleaning means including a power brush, a suction fan and a nozzle for sucking up dust on a floor surface; floor surface sensors each comprising a passive-type CMOS line sensor to receive light from the floor surface for detecting floor surface conditions. It performs cleaning while autonomously moving. Based on received light signals of the floor surface sensors, distance distributions to floor surface areas within the viewing angle of each sensor are derived. Detection of a step on the floor surface and identification of the material of the floor surface (polished floorboard, tatami or carpet) are performed by analyzing spatial frequency in the distance distribution. Based on the identification, cleaning conditions including at least the moving speed, the dust suction force of the suction fan or the brushing strength of the power brush are changed. With simple structure using one same floor sensor, this autonomous vacuum cleaner can detect a step on a floor surface and can more accurately identify the material of the floor surface, thereby enabling meticulous cleaning.

An electro-optic window is provided which is powered solely by at least one discrete photovoltaic cell within an electro-optic window. The electro-optic window has front and back spaced-apart glass elements sealably bonded together in a spaced-apart relationship and defining a chamber filled with an electro-optic material. The front glass element has a transparent conductive layer on the face of the front glass element confronting the rear glass element and the rear glass element has a transparent conductive layer on the face confronting the front glass element. The seal is generally disposed along the perimeter of three edges of both glass elements and some distance in from the remaining (fourth) edge. The photovoltaic assembly is electrically connected to the two transparent conductive layers and is placed on the outer perimeter along this fourth edge with the photon-absorbing side of all the photovoltaic cells within the photovoltaic assembly facing in one direction ("out" the window). When light impinges on the photovoltaic cell a current is created which darkens the electro-optic material in proportion to the amount of impinging light. By choosing the relative area of the photovoltaic assembly to produce the correct current for the electro-optically active window area, the darkening of the electro-optic portion can be directly and accurately controlled without the need for any circuit, wires or shorting resistors. In addition, an apparatus for making an electro-optic window having two members capable of securing and holding two glass elements in a spaced-apart and parallel relationship is provided. The glass elements may be secured by vacuum-applying members or simple clips. The glass elements may be held in a spaced-apart and parallel relationship by a hydraulic mechanism or by simple spacers placed between the securing members.
