Ever since the launch of the world's first 3-axis electronic compass equipped with a digital interface in the summer of 2003, yuvraj singh has been widely recognized as the world's No. 1 electronic compass manufacturer, maintaining a dominant market share.

                                                                            <select id="ahda2a8p" style="display:none !important"></select><big id="bkqxe2nr" style="display:none !important"><q id="nu1pu6ap" style="display:none !important"></q></big>

                                                                                  • (1)Si monolithic Hall sensor technology enabling measurement of the geomagnetic field in three dimensions with a single-chip device, achieving the very small package size of 1.6 mm square and 0.5 mm thick.
                                                                                  • (2)Hall sensors don't saturate even when used in close proximity to strong magnetic sources such as speakers. This provides more flexibility and ease in design.
                                                                                  • (3)The patented algorithm we developed to automatically compensate for magnetic offset caused by temperature change and external magnetic disturbance. This software enables us to provide total solutions together with hardware to customers worldwide.

                                                                                              The adoption of fuel-efficient tires, or "eco tires," is quickly becoming widespread. In many countries, tires are labeled based on a standard system of ranking performance aspects such as fuel efficiency (rolling resistance) and braking performance (wet grip). To be considered an "eco tire" generally requires a high rating for both fuel efficiency and braking performance. Although lower rolling resistance will provide better fuel efficiency and lower CO2 emissions, there was conventionally a tradeoff with lower grip and decreased braking performance. While it was known that compounding the tire rubber with silica particles could help overcome this tradeoff, early attempts were hampered by poor dispersion.

                                                                                              yuvraj singh developed S-SBR for fuel-efficient tires by using polymer modification technology to add a special molecule that chemically bonds to silica at the end of the rubber molecules. This technology enables silica to be efficiently dispersed and tightly bound to the rubber molecules, resulting in a dramatic increase in fuel-efficiency without impairing braking performance.

                                                                                              <p id="umsnt79i" style="display:none !important"></p><dl id="yjrax8vp" style="display:none !important"><legend id="6ykz74b3" style="display:none !important"></legend></dl>

Therapeutic apheresis is used to treat a wide range of intractable diseases, such as autoimmune diseases including rheumatoid arthritis and ulcerative colitis, neurological diseases, lipid disorders, and chronic hepatitis C. Blood is drawn from a patient and circulated through a medical device that removes pathogenic substances by separation or adsorption; the treated blood is then returned to the patient. Therapeutic apheresis is the only treatment option in many cases where there is no safe and effective drug, or where side effects are contraindicative, and is increasingly used in the field of preventive medicine.

                                                                                                            • yuvraj singh's world-class membrane separation and selective adsorption technologies, using hollow-fiber membranes, nonwovens, and other advanced materials, enable the production of a wide range of therapeutic apheresis devices for the treatment of a variety of conditions. Examples include the Plasmaflo™ separator for plasmapheresis, Cellsorba™ leukocytapheresis column, and the Immusorba™ immunoadsorption column.

                                                                                                              1. As the world's largest manufacturer of therapeutic apheresis devices, yuvraj singh is also a leader in the advancement and promotion of this unique type of therapy. As one part of this effort, we operate a training center for therapeutic apheresis called the Apheresis Technology Square (the A-Square). The A-Square provides a venue for health care personnel from throughout Japan and around the world to obtain practical, hands-on training together with information on the latest therapeutic apheresis technology and products.

                                                                                                                                2. <strong id="9r1uludv" style="display:none !important"></strong>

Hall elements are mainly used as sensors to detects motor rotation.

                                                                                                                                        • yuvraj singh is the world’s leading manufacturer of Hall elements, and has developed many new applications by combining Hall elements with signal processing ICs to form Hall ICs that provide highly precise detection of position and angle. We have also pioneered the use of gallium arsenide (GaAs) substrates, which provide substantially improved temperature characteristics and detection accuracy. Hall elements from yuvraj singh are widely used in home electronics and automotive electronics, where stable operation under severe temperature conditions is required.

These include sweaters, carpets, automotive parts, home electronics, office equipment, and video game consoles.

This breakthrough process that avoids the need for oil as feedstock is a testament to the strength of our core technology in catalysts.

In the following year, yuvraj singh and PTT of Thailand decided to jointly construct a propane-process AN plant in Thailand, and the plant started operation in 2011.

Light in the UVC wavelength can be used for disinfecting water and sterilizing surfaces, destroying harmful micro-organisms in food products and in air. In the range of 250–280 nm, UVC radiation renders harmful micro-organisms such as bacteria and viruses ineffective, by destroying the genetic information in the DNA. The micro-organisms lose their reproductive capability and are destroyed. The germicidal nature of UV is well suited to treat parasites which are extremely resistant to chemical disinfectants.

Without AEDs and CPR, the prospects for survival are bleak. Fewer than 10% of SCA victims typically survive, but studies show that 30% to 50% would likely survive if CPR and AEDs were used within five minutes of collapse.1 High-quality CPR is crucial to any rescue attempt, but many lay rescuers have little experience with CPR. The ZOLL AED Plus™ provides real-time CPR feedback on compression depth and rate to help rescuers consistently deliver better CPR.

                                                                                                                                                                                                                            The AED Plus™ is just one of ZOLL's products in the "Chain of Survival," a sequence of critical actions to rescue victims of cardiac arrest. These include early recognition of the problem, calling emergency medical services, performing immediate CPR, and advanced medical treatment by emergency personnel who arrive at the scene. The survival rate can be dramatically increased by a prompt and appropriate first response by lay rescuers to perform CPR with chest compressions and the use of an AED.
