In accordance with an embodiment, a method for producing an aggregate is disclosed comprising mixing incinerator bottom ash (“IBA”) from a municipal solid waste incinerator and pulverized fuel ash (“PFA”) from coal combustion. The method further comprises agglomerating the mixture, such as by pelletizing, and pyroprocessing the agglomerates, such as by sintering or vitrification, to form the aggregate. The addition of PFA to IBA has been found to facilitate production of lightweight and normal weight aggregates. Preferably, the IBA or the mixture of IBA and PFA is wet milled prior to agglomerating. A preferred proportion of IBA to PFA is 40% / 60%. The agglomerates may be coated with an inorganic material to create a surface layer on the aggregate. Organic material may be included in the mixture to increase the porosity of the aggregate. A lightweight sintered aggregate comprising IBA and PFA and an aggregate comprising IBA and PFA are also disclosed.

A vehicle seat assembly 12 is mounted to a vehicle base member 24 such as a riser or a vehicle floor. Weight sensor assemblies 32 for measuring weight on the vehicle seat are mounted to a seat structural component. The weight sensor assemblies 32 each include plate 44 having a bendable center body portion 46 for supporting a strain gage 48. The strain gage 48 measures bending in the center body portion 46 caused by normal weight force applications on the vehicle seat 12. A secondary resilient beam member 34 is mounted between each weight sensor 32 and the vehicle base member 24. The beam member 34 and the weight sensors 32 deflect to prevent failure of the weight sensors 32 in response to an overload force applied in an opposite direction to the direction of a normal weight force application. The beam member 34 prevents permanent deformation of the plate 44 and strain gage failure by allowing the weight sensor 32 to deflect upwardly away from the vehicle floor. An overload stop 68 reacts between the seat structural component and the vehicle floor to prevent seat separation under overload conditions.

Apparatus and methods for treating obesity using chronic cervical vagal nerve stimulation (cVNS) of the left vagus trunk are disclosed. Four men and ten women, average age 46 years (SD±10) were treated with output current typically 0.75 mA, pulse frequency 30 Hz and width 250 or 500 μs, and duty cycle of 30 s power per five minutes. Mean intake weight was 91 kg (SD±27, range 46 to 137 kg) with body mass index (BMI) 43 kg / m2 (SD±5, range 18 to 49 kg / mn2). After 6-12 months, obese patients had marked weight loss while normal weights were maintained. Decrease in BMI was consistently proportional to initial BMI. Average weight loss at one year was 7 kg (SD±3, range −6 to +24) with mean drop in BMI of 2 kg / m2 (SD±3, range −2 to +8)k. All patients denied any major dieting or exercise.

A seismic isolation bearing comprises a lower plate, an upper plate, and a cylindrical roller in rolling contact with an upwardly facing bearing surface of the lower plate and a downwardly facing surface of the upper plate. The lower plate is fixable to a base, while the upper plate is fixable to a superstructure, for example a bridge deck. One or both bearing surfaces are sloped to form a central trough at which the cylindrical roller resides under normal weight of the superstructure, and toward which the roller is biased when relative displacement between the lower and upper plates occurs to provide a constant restoring force. A pair of sidewall members are fixed to the lower plate to withstand strong forces directed laterally with respect to the isolation axis along which rolling displacement occurs, and a pair of sliding guides carried one at each end of the roller provide dry frictional damping as they engage an inner wall surface of a corresponding sidewall member. The isolation bearing preferably comprises a locking mechanism that prevents relative displacement under normal non-seismic horizontal loading, but allows the bearing to function as intended under seismic loading. Visco-elastic or viscous dampers, linear springs, and nonlinear springs such as hardening springs are preferably mounted between the lower and upper plates to reduce bearing displacement, dissipate energy, and otherwise adjust periodic motion characteristics of the bearing. Further embodiments providing isolation along orthogonal X and Y axes are also disclosed.

The invention discloses a field counting and weighing method and a system for chicken. A platform composed of a frame, a support rod and a mesh material is built; a CCD camera is fixed above a weighing platform; pressure sensors for measuring the body-weight of chicken are respectively fixed at four corners of the lower part of the ground weighing platform in a farm; when 1-n chicken naturally stand on the weighing platform, and the total change of the measured body-weight of the chicken is smaller than a set threshold, the CCD camera is triggered to obtain an image of a region of the weighing platform; the quantity of the chicken on the weighing platform can be obtained by image treatment; the mean body-weight of the chicken is calculated according to the total body-weight and the quantity of the chicken on the platform. According to the field counting and weighing method and system, the interference caused by human factors in the weighing process is reduced; the effect on the body-weight of the chicken caused by chicken manure is reduced by a weighing platform design grid; the accuracy of the mean body-weight is improved; the poultry weight at different growth stages is obtained by a fixed time interval starting system; whether a problem exists in chicken house management such as feed supply is judged by comparing with a normal weight gain curve; the feeding time can be reflected.
