Abstract: Examples of techniques for pedestrian accident avoidance are disclosed. Aspects include receiving, by a processor from a first sensor, an indication that a user is moving and activating, by the processor, a second sensor responsive to receiving the indication. Aspects also include detecting, via the second sensor, an obstacle in a path of the user and providing an alert to the user of the obstacle.

Abstract: Embodiments of the present invention generally provide for a system that removes excess thermal energy from a datacenter. In one embodiment, the system includes a holding container with highly thermally conductive surfaces installed in the warmest area(s) of the datacenter. Two substances are released into the holding container and are mixed creating a liquid solution and causing an endothermic reaction. The resulting reaction transfers thermal energy from the datacenter air to the new solution. The liquid solution is then pumped out of the datacenter, where it can be passed through a dialyzing membrane or an evaporation chamber, which separates the liquid solution into its two original substances.

Abstract: A card connector having a housing with a receiving slot and connector pins are provided. An expansion card having docking well regions, contact pads, and backup contact pads is inserted in the receiving slot. The connector pins are connected to the docking well regions on the expansion card. The expansion card is coupled to a servomechanical device that can slide the expansion card to connect the connector pins with the contact pads. Connector pins and contact pads are coated with an interface material that is subject to wearing. Worn interface material can cause weak electrical connections between connector pins and contact pads. Thus, a card connector with a servomechanical device is provided to slide an expansion card within a receiving slot of the card connector for an improved electrical connection between connector pins and contact pads.

Abstract: A method, system and computer program product are provided for implementing dynamic noise elimination. A system frame includes a plurality of acoustical sensory devices monitoring the system for problem frequencies. The system frame includes a plurality of tubes. When the tube is open, airflow is allowed. When identified tubes are closed, quarter-wavelength attenuation is provided for a frequency in a range of frequencies, based upon a length of the tube when closed. Each of the plurality of tubes is selectively controlled to be operable open or closed at a particular length, responsive to identified problem frequencies.

Abstract: An Uninterruptible Power Supply (UPS) for providing power to a computer system. The UPS converts kinetic energy of cooling fluid already being pumped through the computer system to operate a reaction turbine. The turbine drives a flywheel, which in turn can drive a generator in the case of a power failure. A gravity feed may continue to supply cooling fluid to the system, at least for a time, after the power is lost. The turbine can continue to store this energy in the flywheel after power failure thereby extending the ride-through time available.

Abstract: An apparatus, method and computing device including a card edge contact system is provided. A card edge connector housing for receiving a card is provided. A substrate is provided and spaced a distance away from a housing base portion of the card edge connector housing to form a space therebetween. Contact pins collectively defining an upper contact section, a lower contact section and a compliant section connecting the upper and lower contact sections are disposed within the card edge connector housing and the substrate. The upper contact section has an open end with a restricted contact portion for contacting the card. The resilient, compliant section is disposed within the space and is configured to compress to absorb a force from the substrate that would otherwise be transmitted to the upper contact section via the lower contact section.

Abstract: Embodiments of the present invention generally provide for a system that removes excess thermal energy from a datacenter. In one embodiment, the system includes a modular holding container with highly thermally conductive surfaces capable of installation in any of multiple receiving points of the datacenter. Two substances are released into the holding container and are mixed creating a liquid solution and causing an endothermic reaction. The resulting reaction transfers thermal energy from the datacenter air to the new solution. The liquid solution is then pumped out of the datacenter, where it can be passed through a dialyzing membrane or an evaporation chamber, which separates the liquid solution into its two original substances.

Abstract: A thermoelectric generation device is configured for mounting on cooling tubes of a heat exchanger of a computer room air conditioning unit in a data center. A first type of Seebeck material and a second type of Seebeck material are arranged in a matrix and connected in series. An electrically insulating, but thermally conducting plate is located on either side of the device. The device is mounted physically on cooling tubes of the heat exchanger and exposed on the other side to the warm air environment. As a result of the temperature difference a voltage is generated that may be used to power an electrical load connected thereto.
