Operating a laptop on your lap is not comfortable in summer, an old slow laptop drives you crazy. Cooling down will increase speed significantly. Two key factors impact the performance: endless software updating and limited air circulation space. A tiny space resist air flow and heat dispel, increasing space under laptop is more efficient than added a fan.
Summary
As times are changing, so are the way that doctors perform their duties. A new trend in nursing has arisen with the coming of the Registered Nurse Practitioner. This is a Registered Nurse that has obtained a doctorate level degree. This allows for doctor to not be present during the time when the nurse is practicing;
The 3-terminal converter is built with HV IGBT transistors with 6,5kV blocking voltage. Transistors are controlled by fiber optic from DSP and FPGA based controller. Entire device consists of three subcircuits, which create configurable bidirectional multilevel converter, based on "DIODE CLAMPED" structure. The first converter is composed of three active rectifiers connected in series, supplied by isolation transformer.
3,000 MILE CAPACITOR POWERED ELECTRICAL VEHICLE
Crystalline Energy Research Corporation (CER) has designed a revolutionary new Capacitor Energy Pack (CEP) for Electrical Vehicles (EVs) using Multi-Layer Ceramic Capacitors (MLCCs). The MLCCs utilize CER’s novel and developmental capacitor dielectric materials that have K (Dielectric Constant) factors in excess of 300 hundred million. The CEP would contain 12,000 MLCCs;
Most of the 3D phones in the market are basically displaying pseudo-3D images on 2D planes by utilizing the human binocular disparity. With reducing feature size of transistors, and increasing much more sophisticated and powerful processors, sensors, lasers and software tools, it is time to have a real 3D phone.
This design is to use a standard powder feeder that is available from sources such as Praxair or Thermach. It uses a pulsed laser to melt powder and feedback to determine the state of the melt puddle. The feedback is from an optical pyrometer that has a mechanical shutter to protect it from the laser,
Custom, compact, high performance air-cooled heat sinks, designed to meet the most demanding electronics cooling requirements in both commercial and military applications. This product is the result of the DARPA Research & Development program, entitled Micro- technologies for Air-Cooled Exchangers (MACE), to advance the air side heat transfer performance over current State-of-the-Art heat sinks.
Coronary Artery Diseases (CAD) are a major cause of heart attack events which may lead to disabilities and death. Recent advances in CAD diagnosis include computed aided and physical 3D printed models. Both methods are computer coronary reconstruction dependent.
This work enlists a comprehensive method for computer coronary reconstruction and physical model 3D printed,
To reduce the cost of patient care, a novel type of microprobe that measures the levels of drugs, hormones, or proteins in 1 drop sample of a biologic fluid has been designed. With this device physicians can diagnose various diseases, monitor progress of a therapy,
Future engines must meet tough fuel economy and emissions standards without sacrificing power. Variable valve actuation (VVA) can help, but current engines with VVA all have camshafts, so they are not fully variable. LIM Technology has invented a pneumatically actuated, digitally managed valve which is fully variable and requires no camshaft.
