The cover plate covers on the bottom plate. The cover plate defines a cutout. The dust collection box is placed on the bottom plate via the cutout. The dust cleaning apparatus is slidably mounted on the bottom plate. The dust cleaning apparatus moves relative to the heat sink to sweep dust of the heat sink into the dust collection box.

Abstract: A heat sink mounting device includes a touching plate and a mounting member. The touching plate defines a locking hole. The mounting member includes a locking post. The locking post includes a body and two protrusions protruding from the body. An inner surface of the locking hole defines two cutouts. The touching plate includes two blocking blocks extending from an edge of the locking hole on a bottom surface of the touching plate. The two protrusions extend out of the two cutouts and abut the bottom surface of the touching plate. One of the two protrusions is located between the two blocking blocks, to prevent the body from rotating freely in the locking hole.

Abstract: An apparatus, system and method are provided for testing a battery-powered electronic device-under-test in a transport frame engaged with a test fixture. A transport frame power supply is arranged to provide power to the DUT in a pre-testing stage. A switching circuit is arranged to switch from the transport frame power supply to a test fixture power supply in response to receiving a power switching signal indicating satisfaction of a pre-testing condition. Power from the test fixture power supply can then be switched back to the first transport frame, or to a second transport frame, to begin testing a second DUT. The ability to start a DUT test without having to wait for the DUT to boot-up in the test fixture reduces test time and increases efficiency of use of test equipment.

Abstract: Systems (100, 200) and methods for providing TDMA communication. The methods involve determining a channel quality of an uplink channel. A communication delay is set equal to an integer value “K”. “K” is selected based on the channel quality. “K”?“N”. “N” is a total number of frames of a time slot of a TDMA signal (400). Thereafter, First Message Data (FMD) is communicated over the uplink channel in a first time slot (A1) of an uplink signal (1000, 1100, 1200, 1400, 1500, 1600). An Error Control Process (ECP) is performed using FMD to at least identify First Error Free Message Data (FEFMD). Filler data and/or at least a portion of FEFMD is communicated over a downlink channel in a last “N?K” frames of a time slot (A1) of a downlink signal (1050, 1150, 1250, 1450, 1550, 1650), when “K”<“N”.

Abstract: Methods, computer readable media, and apparatuses for automatically recalibrating risk models are presented. An identifier of a modeling function may be received. The modeling function may have at least one input variable and a first set of one or more coefficients. Updated performance data that includes at least one input value corresponding to the at least one input variable may be received from a data source. Then, a second set of one or more coefficients may be calculated for the modeling function based on the updated performance data. If it is subsequently determined that the modeling function more accurately models the updated performance data when the second set of one or more coefficients is used in computing a result of the modeling function, then the first set of one or more coefficients may be replaced with the second set of one or more coefficients to recalibrate the modeling function.

Abstract: A high resolution, compact size and low cost multi-degree-of-freedom geometric error measurement system for simultaneously measuring four geometric errors, horizontal straightness, vertical straightness, pitch and yaw. The pitch and yaw error measurements are based on a new method of angle measurement in turn based on the internal reflection effect at an air/glass boundary. The method uses a differential detection scheme to largely reduce the inherent non-linearity of the reflectance versus the angle of incidence in internal reflection. With non-linearity reduced, the displacement of the angle of incidence can be determined accurately by measuring the reflectance. The resolution and measurement range are determined by the initial angle of incidence, the polarization state of light, and the number of reflections. Compared with interferometers and autocollimators, this method has the advantage of a simple sensor design for applications ranging from very wide measurement range to extremely high resolution.
