Disclosed are a system and method for providing certifiable shielded cabinets and rooms, or pods, to protect devices, equipment and people from electromagnetic interference such as electromagnetic pulse, and directed energy attack. The method simulates the separate electric and magnetic shield requirements and capabilities of each type of materials, simulating them separately and together to form a combined set of materials layered for an enhanced electromagnetic shield that is lighter weight and less expensive. Further disclosed is a system and method for SCADA, RFID, and OID monitoring and controls to enable initial and ongoing testing and control.

In a heat-pump water heater, a control unit has a heat-radiation determining means for determining a heat radiation from refrigerant to outside air in an air heat exchanger based on a water temperature flowing into a water heat exchanger, and the control unit selectively performs a general cycle operation and a bypass operation in accordance with a determination result of the heat-radiation determining means. That is, when the water temperature flowing into the water heat exchanger is lower than 60° C., the general cycle operation is performed. On the other hand, when the water temperature is equal to or higher than 60° C., the bypass operation is performed.

A catheter and catheter system can use energy tailored for remodeling and / or removal of target material proximate to a body lumen, often of stenotic material or tissue in the luminal wall of a blood vessel of a patient. An elongate flexible catheter body with a radially expandable structure may have a plurality of electrodes or other electrosurgical energy delivery surfaces to radially engage the luminal wall when the structure expands. Feedback using one or parameters of voltage, current, power, temperature, impedance magnitude, impedance phase angle, and frequency may be used to selectively control the delivery of energy.

A brushless counter-rotating electric apparatus, motor, wheel hub motor, and associated vehicle includes a brushless counter-rotating electric motor that has oppositely rotating armature and stator components, oppositely rotating armature and stator output drives and, when associated with a vehicle, a control assembly for speed-on / off control of the motor and a portable electric power supply.

A high-frequency heating apparatus comprises a heating chamber, a high-frequency generator, a waveguide, an antenna, a motor for rotating the antenna, and a stage (6) provided above and near the antenna to partition the heating chamber and made of dielectric. A rotary base on which an object to be heated is mounted is provided on the stage. A first magnet is provided to the antenna. A second magnet is provided on the rotary base at a place corresponding to the first magnet on the rotary base. By utilizing the magnetic coupling between the first and second magnets, the rotary base is rotated in synchronism with the rotation of the antenna. While maintaining the advantages of conventional antenna high-frequency heating apparatuses, the heating efficiency by grill heating or oven heating is enhanced, and minute heating uniformness is achieved.

The invention relates to the calculation of 2D images from a 3D model, wherein the 2D images may be generated on a computer device and stored on a server for subsequent display on a client device.

The invention belongs to the field of metal material molding and processing, in particular relates to a mill array for producing an ultra-fine crystal bar and a milling method thereof. The milling method comprises the following steps: a coarse milling section, a middle milling section and a finish milling section with a water penetration cooling section at the rear are continuously milled without twist, mills are horizontally and alternately arranged, wherein a post finish milling section is arranged in front of the finish milling section, and water penetration cooling sections are respectively arranged at the rear of the middle milling section and / or the finish milling section. The mill array has strong temperature control capability and effectively solves the problem that the temperature control capability of the prior bar milling lines is insufficient; an ultra-fine crystal bar is milled at low temperature, can be controlled to be cooled after being milled in the middle middling section and the preliminary finish milling section and can be controlled above a transformation point in the finish milling section; heavy draught cumulation deformation is adopted to induce the phase change of ferrite, after being milled, the ultra-fine crystal bar mill can be controlled to be cooled to keep fine crystal left, and organizations which are fined into 3 mu m and use the ferrite as a base body are obtained, thus the strength of the steel can be increased by at least one level through the effects of fine crystal reinforcement and phase change reinforcement without the necessity of adding an alloying element.

Apparatus and methods for regulating gate delays of synchronous and asynchronous digital circuits. Thermally-sensitive circuits include, generally, temperature sensitive voltage sources outputting a voltage signal indicative of the temperature of the digital circuit, where the voltage signal reflects non-linear temperature sensitivity above a predetermined threshold temperature, and delay mechanisms receiving said temperature sensitive voltage signal(s) as input and being configured to automatically continuously modulate the speed of signal propagation through the circuit in response to said voltage signal, thereby causing circuit elements within the circuits to switch less frequently and consequently causing the circuit elements to generate less heat with increasing circuit temperature.

An electric power tool, which uses a DC brushless motor as a drive source and controls the DC brushless motor by a switching element, can include a tubular housing main body portion accommodating the DC brushless motor, and a grip portion protruding from a side portion of the housing main body portion. The switching element is arranged inside the grip portion, and is spaced apart from an electronic circuit board for an electronic component for operating the switching element.

A thermal retention hood for reducing heat loss from a patient's head during and following surgery includes an enclosure configured to cover the face and head of the patient, and configured to retain heat within the enclosure. The enclosure is at least partially transparent, to give a practitioner visual access to a patient's face. The hood further includes a scored line in the enclosure in a position corresponding to the patient's nose and mouth, a second scored line surrounding a region of the enclosure corresponding to the location of the patient's face, and a strap configured to secure an open end of the enclosure around the patient's neck.
