New surface acoustic wave gas sensor of the mass-sensitive type sensitive to the thermal properties of gases
Tập 1 - Trang 372-375 vol.1
The basic principles of a new surface acoustic wave (SAW) gas sensor are described. Being essentially a sensor of the mass-sensitive type, the proposed device possesses certain features of the thermometric SAW sensors and is not only sensitive to the vapors of volatile substances, but capable of detecting gases by their thermal properties as well. This principles consists of making a certain delay...... hiện toàn bộ

Cảm biến nhiệt độ siêu tiết kiệm năng lượng với cấu trúc silicon trên cách điện (SOI) cho các ứng dụng nhiệt độ cao Dịch bởi AI
Tập 2 - Trang 1419-1422 vol.2
Trong nghiên cứu này, các điện trở nhiệt dựa trên cấu trúc hình chữ nhật đơn giản được chế tạo trên ba loại nền phim mỏng (0,1 /spl mu/m) silicon trên cách điện (SOI), phim dày (10 /spl mu/m) SOI và silicon khối, và các đặc tính của chúng được điều tra. Các phép đo xác nhận rằng SOI thực sự có thể cung cấp thêm tự do để tăng nhiệt độ tối đa hoạt động (T/sub max/). Quan trọng hơn, điện trở nhiệt SO...... hiện toàn bộ

A low-cost Internet-enabled smart sensor
Tập 2 - Trang 1549-1554 vol.2
This paper deals with Web sensors with particular attention to data structures and interfacing features described by IEEE1451 standard. A network architecture is proposed to reduce Web-sensor structural complexity. Transducer and electronic datasheets (TEDS) are directly interfaced to Internet through an HTTP-based protocol, that has been inspired by IEEE1451.2 Transducer Independent Interface (TI...... hiện toàn bộ

Magnetic sensors with polysilicon TFTs
Tập 2 - Trang 804-809 vol.2
This paper deals with magnetic position sensors compatible with large area electronics using polycrystalline silicon deposited by a low-pressure chemical vapour deposition (LPCVD) technique. The principle of this large area position sensor is a matrix of thin film field effect transistors (TFT) with two additional Hall probes. The performances of the TFT based cells are linked to the crystalline q...... hiện toàn bộ

Comparison of different control loop concepts for direct distance measurement using photonic mixing devices (PMD)
Tập 1 - Trang 151-155 vol.1
This paper presents two different control loop approaches for distance measurement with photonic mixing devices (PMD). Possible all-analog implementations are pointed out, and measurements with two different loop types using our laboratory PMD system are provided. It is shown that the PI control loop implementation reaches distance accuracy comparable to previous modulation methods, but on the oth...... hiện toàn bộ

A gazing point distance detection system for accommodation assisting glasses
Tập 2 - Trang 905-910 vol.2
Proposes a gazing point distance detection system which is one of the important key issues in order to realize accommodation assisting glasses, automatic focusing glasses which can assist eye focusing for aged persons who suffer from presbyopia. The new system has a tunnel type light path device which consists of very narrow tunnels with the opening of a vertically long rectangle. The tunnels are ...... hiện toàn bộ

Micro-electromechanical systems and test results of SiC MEMS for high-g launch applications
Tập 2 - Trang 1134-1138 vol.2
Micro-electromechanical systems or MEMS are typically used for the measurement of physical phenomena associated with gun launched projectiles and other smart munitions. These devices generally experience not only the harsh environment encountered during initial shock and vibration at gun launch, but also the extremes of high temperature, high pressure and in some cases large electromagnetic fields...... hiện toàn bộ

Miniaturized inductive sensors for industrial applications
Tập 2 - Trang 771-778 vol.2
Measuring distances, position and travel using the inductive proximity sensors (IPS) based on contactless target-approach detection is a widely used technique. In comparison to optical and capacitive technologies the biggest advantage of inductive sensors in industrial applications is the immunity against oil, water and dirt. In addition, current developments and trends in the industrial fields, e...... hiện toàn bộ
