Abstract: An apparatus, system, and method are disclosed for providing power balancing for power supplies. A power module measures an amount of input power for each of a plurality of switching power supplies. A conversion module converts the measured amount of input power of each power supply to a digital power measurement signal. An averaging module determines an average amount of input power per power supply based on a summation of the digital power measurement signal of each power supply. A comparison module compares the digital power measurement signal of a power supply to the determined average amount of input power per power supply. An input power adjustment module adjusts the input power of the power supply to cause the amount of input power of the power supply to be substantially equal to the determined average amount of input power per power supply.

Abstract: An apparatus and system are disclosed for protecting a power distribution unit from an electrical fault. A fuse interrupts a flow of electrical current in response to the electrical current rising above a current rating of the fuse. A current sensor measures the amplitude of the electrical current and outputs a current amplitude signal. A relay interrupts the flow of electrical current in response to an OFF signal. A fault module receives the current amplitude signal and sends the OFF signal to the relay in response to the amplitude of the electrical current exceeding a threshold value. The relay, the fuse, and the threshold value are selected so that a switching time of the relay is less than an opening time of the fuse for an amplitude of the electrical current between the threshold value and a maximum fault current value, so that the relay prevents the fuse from opening.

Abstract: From a third-party process within a social network having a platform policy, a graph of a social network member is queried. The results of the query are passed to a matching process, without violating the platform policy. Content is requested from the process. In response to passing the results, a description of content is received. The content is caused to be made available to the social network member.

Abstract: From outside a social network having a platform policy, causing a third-party program within the social network to query a social graph of a social network member. The results of the query are accessed without violating the platform policy. Based on the results, content is identified to serve to the social network member. The third-party program within the social network is caused to make the content available to the social network member.

Abstract: An apparatus, system, and method are disclosed for providing alternating current (“AC”) power redundancy in power supplies. A first input module is configured to receive a first AC power input waveform. A second input module is configured to receive a second AC power input waveform. A first switch and second switch are controlled by a switching logic module to select one of the AC power input waveforms for use by a power supply. If the first AC power input waveform is present, then it is selected for use. If both the first and second AC power input waveforms are present, then the first AC power input waveform is selected for use. If only the second AC power input waveform is present then it is selected for use.

Abstract: A shield for wheel assemblies formed of a metal band that is inserted into wheels so as to cover and protect the inner surface of the wheels. The shields can be made from stainless steel and used to protect the inner surfaces of aluminum from damage caused by debris that contact a vehicle braking assembly. The shields are secured in the wheels by a mechanical locking arrangement in which the outer ends of the shields snap-fit along outboard rim flanges of the wheels. Adhesives or sealants can be used to secure the shields to the wheels and to prevent moisture and debris from becoming trapped between the shields and inner surfaces of the wheels.
