Abstract: Various implementations described herein are related to determining climate settings of a climate controlled area during a duration of insufficient supply of power. Each of one or more power units may be configured to provide power to the climate controlled area. The climate setting of a survival operating mode of a climate control system of at least part of the climate controlled area may be determined, for example, based on the duration of insufficient supply of power, the total available power, and/or one or more weather condition parameters.

Abstract: A method of optimizing a heat pump energy supply, comprising: sensing the ambient temperature; and responsive to the sensed ambient temperature, selecting one of a first energy source and a second energy source to provide energy for processing a working fluid of the heat pump, the second energy source different than the first energy source.

Abstract: The present disclosure provides for a method and apparatus of providing air conditioning from a waste heat source. A vapor state expander is provided producing mechanical work, and a compressing unit is at least partially operative responsive to the mechanical work output of the vapor state expander. In another exemplary embodiment a second liquid state expander producing mechanical work is further provided, the compressing unit operative further responsive to the mechanical work of the liquid state expander. The apparatus disclosed is further capable of providing backup heating and cooling from an additional power source when the waste heat source is insufficient.

Abstract: A redundant powering system for a powered device receiving power over communication cabling, the redundant powering system comprising: a redundant power supply comprising a first power sourcing equipment and a second power sourcing equipment; a powered device; communication cabling connecting the redundant power supply to the powered device, the communication cabling comprising a first path connecting the first power sourcing equipment to the powered device and a second path connecting the second power sourcing equipment to the powered device, the first and second paths at least partially being constituted of a single structured cable, the at least one powered device comprising at least one signature impedance, the redundant power supply being operable so that power is operably supplied to the powered device from only one of the first and second power sourcing equipment.

Abstract: Apparatus for supplying power to communication devices operating within a Local Area Network (LAN) over LAN cabling, the communication devices including one or more powered devices adapted to receive power over the LAN cabling, the apparatus including a power supply which is adapted to receive power from an unregulated source and to provide therefrom regulated power. The apparatus further includes power distribution and control circuitry, which is adapted to identify the powered devices on the LAN, to receive the regulated power and to generate therefrom respective output voltages for supply to the powered devices. The apparatus is housed in a chassis which retains the power supply and the power distribution and control circuitry as a single module.

Abstract: Power distribution apparatus, for controlling supply of a current from an electrical power source to at least one load, includes a current sensor, which is coupled to provide an indication of a magnitude of the current flowing to the at least one load. A current limiter is adapted, responsive to the indication, to apply a pulse width modulation to the current drawn from the source so as to maintain the magnitude of the current flowing to the at least one load within a predetermined limit.
