Abstract: An exoskeletal gas turbine engine having a rotatable outer shaft and an inner stationary case enclosed in a casing. The engine comprises a compressor section at an inlet end, a combustor section, and a turbine section at an outlet end. Rotating compressor blades and turbine blades are attached to, and extend radially inward from, an inner surface of the outer shaft. Stationary vanes are attached, and extend radially outward from, an outer surface of the inner stationary case. The outer shaft rotates around a front bearing and a rear bearing. An inlet compressor blade arrangement is attached to the outer race of the front bearing. An outlet turbine blade arrangement is attached to the outer race of the rear bearing. The inner race of the front and rear bearings attach to the inner stationary case.

Abstract: A gas turbine engine may include a combustor having an inner wall and an outer wall defining a combustion chamber there between. The inner wall and the outer wall may each have at least one opening into the combustion chamber. The gas turbine engine may also include at least one mobile conduit through which a cooling fluid may flow. The mobile conduit may pass through the combustion chamber from the at least one opening in the outer wall to the at least one opening in the inner wall. The gas turbine engine may further include a first joint and a second joint fluidly connecting the mobile conduit to the at least one opening in the inner wall and the at least one opening in the outer wall, respectively. The first joint and the second joint may enable multiple degrees of freedom of the mobile conduit within the combustion chamber.

Abstract: An information handling system can receive power from a wireless or wired power source. In response to determining the information handling system is coupled to the wired power source, the system decouples the wireless power source from providing power. In response to the system being decoupled from the wired power source, the information handling system couples the wireless power source to the system.

Abstract: A system comprises an AC/DC adapter having a connector. The system also comprises a portable computer that receives said connector. The portable computer comprising a delay circuit coupled to a power transistor that is coupled in parallel with a resistor. The delay circuit causes the power transistor to activate following a time delay after current from the adapter begins to flow through the resistor. As a result of a user beginning to remove the connector from the portable computer, a control transistor is activated to reset the delay circuit.

Abstract: Power is supplied to an information handling system chipset with a single voltage regulator having dual phases. A first phase of the voltage regulator provides power to a low power state power rail in an independent mode to support a low power state, such as a suspend or hibernate state. A second phase of the voltage regulator provides power to a run power state power rail in combination with the first phase by activation of a switch, such as a MOSFET load switch, that connects the low power state power rail and the run power state power rail. Voltage sensed from both power rails is applied to control voltage output so that the run power state power rail is maintained within more precise constraints than the low power state power rail.

Abstract: A voltage regulation steering circuit reads a voltage input code from a device and detects a set of predetermined conditions for gradually counting an output voltage code. Depending upon the set of predetermined conditions, the steering circuit either gradually counts the output voltage code from a predetermined initial voltage code to the voltage input code or gradually counts the output voltage code from the voltage input code to a predetermined low voltage code. As the steering circuit gradually counts from the predetermined initial voltage code, the steering circuit compares the output voltage code to voltage input code until the output voltage code matches the voltage input code. As the steering circuit gradually counts from the voltage input code, the steering circuit compares the output voltage code to the predetermined low voltage code until the voltage output code matches the predetermined low voltage code. The output voltage code is provided from the steering circuit to a voltage controller.
