Abstract: An embodiment of a device includes at least one sensor, a determiner, and a notifier. The at least one sensor is configured to be located on a body portion of a subject and to sense an object. The determiner is configured to determine, in response to the sensor, whether the body portion may contact the object. The notifier is configured to notify the subject in response to the determiner determining that the body portion may contact the object. Such a device (e.g., attached to, or part of, a shoe) may be useful to warn a subject of a potential collision between an object (e.g., stairs, furniture, door jamb, curb, toy) and a body part (e.g., foot, toes) in which the subject has lost feeling, the ability to feel pain, or proprioception. And such a warning may help the subject to avoid inadvertently and repeatedly injuring the body part.

Abstract: Systems and methods are provided for data center cooling by vaporizing fuel using data center waste heat. The systems include, for instance, an electricity-generating assembly, a liquid fuel storage, and a heat transfer system. The electricity-generating assembly generates electricity from a fuel vapor for supply to the data center. The liquid fuel storage is coupled to supply the fuel vapor, and the heat transfer system is associated with the data center and the liquid fuel storage. In an operational mode, the heat transfer system transfers the data center waste heat to the liquid fuel storage to facilitate vaporization of liquid fuel to produce the fuel vapor for supply to the electricity-generating assembly. The system may be implemented with the liquid fuel storage and heat transfer system being the primary fuel vapor source, or a back-up fuel vapor source.

Abstract: A device is provided that converts random movement of extrinsic oscillation from an ocean wave into purposeful movement, such as torque or other motion that can be used to generate electricity. This device may include but is not limited to two major components: 1) a collection unit and 2) a transmission unit. The collection unit represents the interactive part of the device that interfaces with an extrinsic force which provides the randomized kinetic motion that is translated by an actuating arm connected with the transmission unit into pivoting bidirectional movement along at least two directional axes, and may include a series of connected pivoting arms of different lengths. The transmission unit is the portion of the device that converts the pivoting directional movement of the actuating arm or arms into rotation of a drive shaft that is then converted into purposeful torque, and thus, electricity.

Abstract: A gas turbine drives a power generator by rotating a turbine using combustion gas generated in a combustor as a result of supplying the combustor with fuel and compressed air from a compressor, which is provided with an inlet guide vane at a front stage. An operation control device of the gas turbine enables an IGV priority open flag when the inlet guide vane is not fully open and when the system frequency is lower than or equal to a predetermined threshold value ? or there is a request for increasing the output of the gas turbine. When the IGV priority open flag is enabled, the operation control device sets the degree of opening of the inlet guide vane to be larger than before. Accordingly, the output can be increased without having to increase the turbine inlet temperature, regardless of the operational state of the gas turbine.
