摘要： An information handing system includes a transmitter, a receiver, and a differential signal channel. The transmitter provides a differential signal on a pair of differential outputs. The receiver receives the differential signal on a pair of differential inputs. The differential signal channel carries the differential signal from the differential outputs to the differential inputs. The differential signal is provided on the differential signal channel as a voltage swing between a first positive voltage and a first negative voltage with reference to a ground plane of the information handling system.

摘要： A dual axial cable includes first and second signal conductors and a shield. The first and second signal conductors transmit a differential signal. The shield includes a foil wrap spirally wrapped around the first and second conductors to form a plurality of foil wrap sections. Each of the foil wrap sections overlaps an adjacent foil wrap section. The periodicity of a pitch of each of the overlaps varies along a length of the dual axial cable.

摘要： An apparatus includes a transmitter circuit configured to provide a transmitted waveform at a transmitter output, and a first microstrip differential trace extending from a first microstrip differential trace first end to a first microstrip differential trace second end. A first resistor has a first resistor first end coupled to the transmitter output and a first resistor second end coupled to the first microstrip differential trace first end. A second microstrip differential trace extends from a second microstrip differential trace first end to a second microstrip differential trace second end. A second resistor has a second resistor first end coupled to the transmitter output and a second resistor second end coupled to the second microstrip differential trace first end. A first receiver circuit has a first receiver circuit input coupled to the first microstrip differential trace second end, the first receiver configured to provide a first received signal. A second receiver circuit has a second receiver circuit input coupled to the second microstrip differential trace second end, the second receiver configured to provide a second received signal. A processor may receive the first received signal and the second received signal and perform digital signal processing on the first received signal and the second received signal, detect a coolant leak, and provide an alert upon detection of the coolant leak.

摘要： An electrical break is created in a via that would ordinarily electrically connect different layers of a printed circuit board. The electrical break severs the via into two or more separate and electrically disconnected vias. The electrical break may be placed at any depth along the via, thus demarking different purposes associated with different layers.

摘要： An information handling system includes an information handling subsystem, a power supply unit operably connected to the information handling subsystem, and a battery power subsystem operably connected to the information handling subsystem and having a controller. The controller configured to enter a learning mode of the battery power subsystem when the information handling subsystem is in a normal power state, enable a regulator output of a regulator of the battery power subsystem to provide power from a battery of the battery power subsystem at a learning mode current limit and at a learning mode voltage level to the information handling subsystem, provide, via the regulator output, power from the battery at a constant learning mode current level and at the learning mode voltage level to the information handling subsystem, and determine that the battery has been discharged to an acceptable discharge level.
