A linear lamp (lighting bar) comprises: a linear array of LEDs and an elongate lens disposed over the array of LEDs. The lens comprises a generally concave central portion (divergent) and generally convex edge portions (convergent) and is configured such that in operation a variation in illuminance is less than 10% over an angular range of at least 90°. In one arrangement the concave central portion comprises an inner generally concave surface that faces the LEDs and an outer substantially planar and/or generally concave surface overlying the LEDs. The convex edge portions can comprise an outer generally convex surface. The lamp is suited for use in a light box for light emitting signage, under-cabinet/under-shelf lighting, cove lighting, retail display lighting, advertisement display lighting, wall sconce lighting and outdoor or indoor area lighting

A virtual thermostat to control an air condition of any target zone in an HVAC controlled space. The thermostat comprising of a 3D scanner to provide a 3D point cloud of the controlled space; a CAD-application algorithm to modify the point cloud into a 3D model of the space; a control panel for a user to input a set of boundary and initial conditions and a desired air condition at the target zone inside the controlled space; a fluid flow software having means to read said 3D model and to determine a spatial velocity and temperature distributions throughout the controlled space, and to calculate an average temperature for the target zone in the controlled space; a control system to manage the air inlet flow to control the temperature at the target zone in the controlled space by comparing the calculated average temperature of the target zone with a user defined temperature and to turn the HVAC system ON and OFF.

In a hybrid vehicle including an engine; a generator for generating electrical power from the engine; a battery charged with electrical power generated by the generator; and a motor driven by electrical power generated by the generator or by electrical power output by the battery, and with a view to reducing energy consumption from the battery without using complicated control operations while preventing overcharging of the battery, the hybrid vehicle further includes a motoring control unit for starting motoring, i.e., mechanical driving of the engine, in addition to regenerative power generation when a state of charge of the battery reaches a first set value and stopping the motoring of the engine when the state of charge of the battery reaches a second set value. A battery management unit is also provided for starting power generation from the engine when a state of charge of the battery becomes higher than a third set value and stopping the engine when the state of charge of the battery reaches a fourth set value. Engine motoring control during regeneration and control of power generation by the engine can be separately performed.

The invention discloses an energy-saving coach and a coach body covering method. The energy-saving coach comprises a coach body framework and panels, wherein the panels include the first layer of panel and the second layer of panel. The first layer of panel is adhered on the coach body framework through four-proofing adhesives and rivets, and the second layer of panel is adhered with heat-insulation materials through four-proofing adhesives and is further fixed on the first layer of panel through pressing strips. The coach body covering method includes the following steps of A, primarily covering; B, secondarily covering and heat insulating; and C, adhering the heat-insulation materials to a covered layer subjected to the primary covering and fixing by the pressing strips. The energy-saving coach and the coach body covering method have the following advantages that the panels are adhered on the coach body framework, resonance noise of the coach body at the four-proofing adhesive position of the coach body framework is reduced greatly, noise pollution of the coach is effectively reduced and physical and mental health of drivers and passengers are benefited. Besides, the coach body is coated by the heat-insulation materials, cool air in the coach body can be kept for a long time, the air conditioning system can be saved and energy consumption is reduced accordingly.

The invention discloses an annular piece combined forging method, and belongs to the technical field of forging. The problems that two components need to be produced according to the two components, the forging cost is increased, forging energy waste is large, and raw material consumption is large are solved. According to the annular piece combined forging method, a combined production manner is used for combining the two components the same in material for forging, the method comprises the following steps that round steel is arranged in a forging die of a forging press, a first forge piece and second forge piece combined forging force piece ring blank is formed, an annular piece of a combined forging force piece is placed in a punch press to conduct recess punching, the ring blank of thecombined forging force piece is cut off, and a first forge piece blank and a second force piece blank are obtained. By means of the annular piece combined forging method, one punching waste is omitted, raw material consumption is reduced, energy consumption is reduced, the forging manual operation is reduced, the forging efficiency is improved, and output per shift is increased. In addition, the combined force piece is divided into the two components, the method for punching, cutting-off and hobbing through a lathe can be adopted for proceeding, and materials are saved to the maximum degree without procedure increasing.

A wet and a wet and dry dust removal apparatus, the latter for drilling applications including a housing, adapted to contain powered air induction means to induct air contaminated with particulate matter, water spraying means adapted to spray a mist of water into the induced air stream to capture the particulate matter, water removal means adapted to remove water droplets containing the particulate matter, the water removal means positioned in the housing parallel angle to the direction of the air flow, wherein the paralleled position by presenting a minimal drag profile in the air flow reduces the air pressure and velocity required to remove dust for a given volume of air, so that the energy consumption of the air induction means is correspondingly reduced.
