    摘要： A bolt locking structure for a waterproof LED lamp contains: a first casing and a second casing. The first casing includes multiple first protrusions and multiple first recesses which are arranged on each of four peripheral walls thereof respectively. The second casing includes multiple second protrusions and multiple second recesses which are arranged on each of four peripheral walls thereof respectively. The multiple first protrusions retain with the multiple second recesses, and the multiple first recesses retain with the multiple second protrusions. Multiple through holes are coaxial and form on each peripheral wall of each of the first casing and the second casing respectively, wherein each of the multiple through holes passes through each of the multiple first protrusions and the multiple second protrusions, such that each of multiple connection bolts inserts into the multiple through holes, thus locking the first casing and the second casing together.

    摘要： A packaging structure for an LED lamp contains: a casing, a substrate, a printed circuit board (PCB), and at least one locking element. The casing, the PCB, and the substrate are stacked and adhered together. The at least one locking element respectively inserts into and retains with two connection gaps between the casing and the substrate so as to fix the casing and the substrate together. The substrate includes a stepped groove defined on a central portion thereof and facing the casing, and the stepped groove of the substrate has a first accommodation part and a second accommodation part. A size, a profile, and a depth of the first accommodation part correspond to a size, a profile, and a thickness of the casing. A size, a profile, and a depth of the second accommodation part correspond to a size, a profile, and a thickness of the PCB.

    摘要： An axial flow impeller includes a hub, at least three base blades, and a cover blade detachably mounted to each base blade. When the impeller is applied in a medium environment having a high density and viscosity, the impeller will meet the requirement only by virtue of the base blade with the cover blade being removed. When the impeller is applied in a medium environment having low density and viscosity, the cover blade can be mounted in the front and/or rear of the base blade in order to improve the efficiency of the impeller. In this case, the consumption of electrical power can be reduced significantly while producing an equivalent propulsive force, thereby being advantageous for energy conservation. Therefore, the impeller can be adaptable to different medium environments and efficiency requirements, and thus can have good adaptability, need minimal investment cost and can be convenient to use.

    摘要： A document scanner comprises a first image sensor unit (32) and a second image sensor unit (30) and a scanning mechanism (70, 72, 76, 80) for causing relative movement between a document and the units so that the units scan the document in a scanning direction. The first unit (32) is situated ahead of the second unit (30) in the scanning direction and partially overlaps the second unit. Each sensor unit has a respective linear array (44) of electromagnetic radiation detectors and one or more light guides (48, 49) for directing light from a respective one of two imaging lines (63) on to the detectors, wherein, in use, the imaging lines scan the document to capture data representative of two respective sets of scan line portions for combination to obtain a succession of scan lines for the document, the one or more light guides of the first unit (32) are angled rearwardly with respect to the scanning direction, whilst the one or more light guides of the second unit (30) are angled forwardly with respect to the scanning direction, so as to reduce the distance with respect to the scanning direction, between the imaging lines (63).

    摘要： Various technologies described herein pertain to evaluating service provider compliance with terms of a performance service level agreement (SLA) for a tenant in a multi-tenant database system. The terms of the performance SLA can set a performance criterion as though a level of a resource of hardware of the multi-tenant database system is dedicated to the tenant. An actual performance metric of the resource can be tracked for a workload of the tenant. Further, a baseline performance metric of the resource can be determined for the workload of the tenant. The baseline performance metric can be based on a simulation as though the level of the resource as set in the performance SLA is dedicated to the workload of the tenant. Moreover, the actual performance metric can be compared with the baseline performance metric to evaluate compliance with the performance SLA.
