A power supply system for supplying a grid power to a building includes a power generator, a power storing device, and a power controller. The power generator generates off-grid power from a predetermined energy. The power storing device stores the grid power and the off-grid power and supplies the stored power to the building. The power controller controls consumptions of the grid power and the off-grid power. The power controller calculates predicted consumption data related to power consumed in the building and predicted generation data related to power generated by the power generator. The power controller calculates a charging-discharging schedule for the power storing device based on the predicted consumption data and the predicted generation data by formulating the charging-discharging schedule as a mixed integer programming problem.

A method is provided for device detection by a base station comprising receiving a plurality of signals over a preamble subframe from an endpoint. The plurality of signals are attempting to access an access group of the preamble subframe. Additionally, the plurality of signals are received on a random access channel using a wireless network. Further, the plurality of signals have a plurality of last gasp messages (LGMs). The method additionally comprises determining an allowable rate of collisions for the plurality of signals and determining an actual rate of collisions for the plurality of signals. The method includes increasing the size of the access group allocated to the plurality of signals having the plurality of LGMs, based on whether the actual rate of collisions exceeds the allowable rate of collisions.

A system and method utilize a redistribution layer in a flip-chip or wirebond package, which is also used to route signals to bumps, as a layer for the construction of an on-chip inductor or a layer of a multiple-layer on-chip inductor. In one example, the redistribution layer is surrounded by dual-layer passivation to protect it, and the inductor formed thereby, from the environment and isolate it, and the inductor formed thereby, from the metal layer beneath it.

In this lubricant distribution acquisition device (1), neutron beams that have been transmitted through a bearing (X) are converted into electromagnetic waves, and, by using the received electromagnetic waves to form images based on rotation angle signals that are output from an encoder (5) and show a rotation angle of the bearing, lubrication distribution data that shows the distribution of a lubricant inside the bearing is acquired. As a result, it is possible to make the pitch of the rotation angle uniform in each set of imaging data, and to thereby accurately ascertain the behavior of the lubricant inside the bearing.
