摘要： A power system including an uninterruptible power system (UPS) and a maintenance bypass panel (MBP) The UPS has an input to receive input power and an output to provide output power. The MBP has an input to receive the output power provided by the UPS and an output to provide the input power to the input of the UPS. A busbar is configured to couple one of the input of the UPS to the output of the MBP and the output of the UPS to the input of the MBP. The busbar has a first region to couple to one of the input and the output of the UPS, a second region to couple to one of the input and the output of the MBP, and a measurement region. A cover shields the busbar from inadvertent contact and includes a small diameter aperture to permit access to the measurement region of the busbar.

摘要： In one aspect, the invention provides a method for overcurrent sensing including; generating an analog output signal representative of a sensed AC current, generating a digital representation of the analog output signal using a plurality of discrete samples, determining those of the plurality of discrete samples having a substantially identical magnitude and estimating an amount of overcurrent in the sensed AC current by evaluating those of the plurality of discrete samples that have the substantially identical magnitude. In some embodiments, the substantially identical magnitude is a maximum magnitude represented by the digital representation.

摘要： A cooling unit (10) includes a housing (12) having a front (14) and a back (16), one or more fans (28) provided at either the front (14) or the back (16) of the housing (12), and a V-shaped evaporator (30) positioned within the housing (12) and coupled to a source of liquid refrigerant. The V-shaped evaporator (30) has two panels extending from adjacent to the bottom (22) of the housing to adjacent to the top (24) of the housing (12) when positioning the evaporator (30) in the housing (12). The arrangement is such that an inside of the panels of the evaporator (30) faces air being drawn through the housing (12) of the cooling unit (10) by the fan (28).

摘要： Systems and methods of re-enumerating peripheral devices operatively connected to a computer system are provided. In one example, a system is configured to disable an existing connection between an operating system and a peripheral device established through a device driver by re-describing the peripheral device to the OS. In another example, the system can be further configured to execute operation(s) on the peripheral device without new driver installation using communication channels native to the OS. Once the operation(s) are complete, the system can be configured to restore the existing connection.

摘要： Systems, methods, and computer-readable mediums are provided for improving the efficiency of a filter-type oil separator in a cooling system including a compressor that pumps a mixture of lubricating oil and refrigerant through the filter-type oil separator. The filter type oil separator is configured to receive a first portion of the mixture from the compressor, and a bypass line is configured to bypass a second portion of the mixture around the filter-type oil separator. The bypass line ensures a sufficient amount of oil is present in the compressor.
