Recent Patents on Engineering - Volume 10, Issue 3, 2016

Background: Unmanned Aerial Vehicle (UAV) technology has exploded in recent years. Presently UAVs are beginning to be major in roads into geographical mapping, site inspection, agriculture, and search and rescue. Methods: This paper reviewed patents and papers worldwide related to both hardware and software for the construction and deployment of UAVs and is intended to provide a snapshot of currently available U Read More

Background: Intelligent, adaptive, wireless, and GPS-enabled heating, ventilation and air conditioning (HVAC) control devices have significant potential with regards to energy efficiency and cost savings through reduction of utility bills when implemented into the mechanical controls of a home. Objective: The aim of this paper is to conduct a patent search in order to evaluate the recent advances on smart HVAC control d Read More

Background: The review of patents reveals that with the high incidence of breast cancer, the therapeutic methods are further becoming increasingly important. In traditional breast interventional procedures, particle was manually injected into the body of cancer patients by a doctor according to the image. However, the operation could not be performed with image navigation in real-time, and the manual implantatio Read More

Background: A significant effort has been underway to put renewable energy sources at the heart of the current energy model. Hydrogen produced via water electrolysis has been identified as one of the most promising means to help achieve this goal, especially by enabling energy storage in a sustainable and non-polluting way. In recent years, this situation has triggered novel developments in water electrolysis technologies an Read More

Background: The review of patents reveals that the Microstrip patch antennas are frequently used in UWB technologies, due to its advantages such as lightweight, ease of integration, small size and compactness. A novel printed monopole antenna based on quadratic Bézier curves for ultra-wideband applications, has been introduced. Methods: The goal of this research focuses mainly on antenna’s miniaturization with high ef Read More

Background: When fire occurs, smoke spreads from the bottom of the building to the top through the stairwell, and spreads over the stairwell. This horizontal movement of high temperature smoke is dangerous because people can only reach the subway exit by stairs during the fire. Methods: To control horizontal movement of the smoke, a novel fire smoke-free double-jet air curtain system (DJACS), which has been granted the C Read More

Background: Poisson’s ratio is one of the basic concepts of mechanics. The review of patents reveals that the radial deformation of a cylindrical specimen is one of the main parameters for the determination of Poisson’s ratio. However, the widely used chain-type circumferential extensometer needs to be fixed onto such samples and will result in damage when the tested specimens are weak. Methods: To provide Read More
